For unit selection at other fouling factors. biological growth (algae. The water flow switch should be calibrated accordingly. Using unclean and untreated water may result in scale and deposit formation causing reduced cooler efficiency or heat transfer and corrosion or pitting leading to possible equipment damage. At altitudes substantially above sea level. the pH value of the water flowing through the cooler must be kept between 7 and 8. Over sizing adversely affects the operating efficiency due to erratic system operation and excessive compressor cycling which also results in reduced compressor life.

Over sizing chillers beyond a maximum limit of 5 – 10 % in order to assure adequate capacity or considering future expansions is not recommended.000018 m2-0C/W). clays. stratification and poor control and flow rates beyond the maximum limits cause excessive pressure drop and severe tube erosion. As fouling factor is increased. Design flow rates below the minimum limits will result in laminar flow causing freeze-up problems. dirt. an oversized unit is usually more costly to purchase. In such applications. Zamil recommends that a water treatment specialist is consulted to provide and maintain water treatment. units operate more efficiently when fully loaded rather than larger equipment operating at partial capacities. When any application varies from these guidelines. The Zamil electronic selection program may also be utilized for this purpose. this is particularly critical with glycol systems.5.00010 hr-ft2-0F/Btu (0. water flow rate must not vary more than ± 5% from the design flow rate. consult Zamil Air Conditioners for specific recommendations.

WATER FLOW RATES AND COOLER PRESSURE DROP The maximum and minimum water flow rates for all unit models and the pressure drop chart are provided in this catalog. During unit operation. In order to prevent corrosion and pitting. These chillers are suitable for operation with well maintained water systems. performance and reliability of units is often dependent upon proper compliance with these recommendations. EFFECT OF ALTITUDE ON UNIT CAPACITY The tabulated performance data provided in this catalog are for use at or near sea level altitude applications.APPLICATION GUIDELINES INTRODUCTION These guidelines should be considered when designing systems and their installation utilizing Zamil ARY series liquid chillers. Operation of two chillers at higher loading is preferred to operating a single chiller at or near its minimum possible capacity. In addition. It should be noted that. The design water flow rate must be within this range. flow rate and pressure drop are higher than with water. For unit selection at these higher altitudes. the decreased air density will reduce condenser capacity and therefore unit capacity. install a single chiller for the present load requirement and install a second chiller for the foreseen additional load demand due to expansion. The tabulated performance data provided in this catalog is based on a chilled water temperature drop of 100F. 45°F 340 GPM 120 TR Chiller 45°F 82. A standard chiller can be used for this application as shown in the following basic schematic layout (single mixing arrangement). Our chillers can be utilized for these applications by selecting the chiller based on the specific process load and making a suitable piping and mixing arrangement in order to bring the flow rates and/or water temperatures relevant to the chiller within acceptable limits.6°F 500 GPM 65°F 240 GPM Example 2: An application requires 192 GPM of water at 650F and the return water temperature is 800F. Units may be operated at any desired temperature drop within the range of 5 to 150F as long as the temperature and flow limits are not violated and appropriate correction factors are applied on the capacity and power input. A standard chiller can be used for this application as shown in the following basic schematic layout (dual mixing arrangement).2 GPM 45°F 257.COOLER FLUID (WATER OR GLYCOL) TEMPERATURES RANGE Unit can start and pull down from 950F (350C) entering fluid temperature. It should be noted that temperature drop outside the aforesaid range is not permitted as it is beyond the optimum range of control and could adversely affect the functioning of microprocessor controller and may also prove to be detrimental for the equipment. FLOW RATES AND/OR WATER TEMPERATURES OUT OF RANGE Certain applications (particularly process cooling jobs) call for flow rates and/or water temperatures that are outside the above mentioned limits/range.4°F 80°F 340 GPM 82. The design entering chilled fluid temperature range is 50 to 600F.8 GPM 53.4°F 340 GPM 53.8 GPM 65°F 192 GPM Load 120 TR 80°F 109. Example 1: An application requires 240 GPM of water at 450F and the return water temperature is 650F. 45°F 240 GPM 45°F 500 GPM 200 TR Chiller Load 200 TR 45°F 260 GPM 54. The Zamil electronic selection program can be very handy in selecting equipment at different temperature drops.2 GPM 36 80°F 192 GPM . The design leaving chilled fluid temperature (LCWT) range as mentioned earlier in the tabulated performance data is 40 to 500F. The design cooler temperature drop (ΔT) range is 5 to 150F. energy economics. installation requirements and others to determine the best arrangement for his project. the multiple chilled streams are combined again in a common line after chilling. liquid to be chilled is divided among the liquid chillers. flexibility. nature of load and configuration of building. flow rate and pressure drop. Parallel arrangements permit adding chillers in the future for plant expansion with the appropriate considerations beforehand. As mentioned above. Zamil recommends the parallel arrangement for design temperature drops (ΔT) up to 150F and the series arrangement beyond that i. the chilled liquid pressure drop may be higher unless coolers with fewer liquid-side passes or baffles are used. Series chiller arrangements can be controlled in several ways based on the water temperatures depending on cooling demand. Multiple chiller arrangements offer the advantage of operational flexibility. No over chilling by either unit is required. two basic multiple chiller systems are used: parallel and series chilled water flow. units of same size should be preferred over different sizes to facilitate balanced water flow. and compressor power consumption is lower than it is for the parallel arrangement at partial loads. Water temperatures (EWT or LWT) can be used to cycle units On and Off based on the cooling demand. 16 to 200F.. In the parallel arrangement. standby capability is desired. therefore appropriate correction factors from the aforementioned table in this catalog should be applied. Some suggested arrangements with basic schematic layouts are as follows: 37 . A valved piping bypass is suggested around each chiller to facilitate future servicing as it gives the personnel an option for service without a complete shutdown.e. standby capacity and less disruptive maintenance. lower design flow and resulting installation and operational cost savings. The designer must weigh the pros and cons of cost. The system piping circuit (load distribution circuit) should be basically parallel piping either Direct Return or Reverse Return system with a good pumping arrangement. Complete design details on these parallel and series chilled water flow arrangements can be found in the ASHRAE handbooks and other design literature which should be referred by the designer in preparing his detailed designs. A multiple chiller arrangement should be provided if the system load is greater than a single chiller capacity. Also. Starting in-rush current is reduced. It is also possible to achieve higher overall entering to leaving temperature drops.COOLER FREEZE PROTECTION If the unit is located in an area where ambient temperatures fall below 320F (00C). In the series arrangement.30C) below minimum operating ambient temperature. The method of circuiting and pumping is a judgment decision by the designer. This glycol solution must be added to the water system loop to bring down the freezing point of water to a difference of 150F (8. as well as power costs at partial-load conditions. which may in turn provide the opportunity for lower chilled water design temperature. In all cases. they offer some standby capacity if repair work must be done on a chiller from a set of duty chillers. MULTIPLE CHILLER ARRANGEMENT OR PLANT CONFIGURATION A multiple chiller system has two or more chillers connected by parallel or series piping to a common distribution system. PIPING ARRANGEMENTS AND PLANT LAYOUT Our chillers are suitable for incorporating in ‘Two Pipe’ single temperature systems or ‘Four Pipe’ independent load systems. It is mandatory that cooler flow rates must be balanced to ensure proper flow to each chiller based on its respective capacity. it must be ensured that the design water flow is constantly maintained through the chillers at all stages of operation. large temperature drop (greater than 150F) is desired or application calls for splitting the total capacity for better part load operation. In designing a multiple chiller plant. Using this glycol solution causes a variation in unit performance. cooler protection in the form of Ethylene Glycol Solution is required to protect the cooler and fluid piping from low ambient freeze-up. the various load devices are controlled first. then the source (chillers) system capacity is controlled to follow the capacity requirement of the loads. Single or multiple chillers with constant water flow through chillers and load system: CHWS Load Chiller 3-Way Valve Load 3-Way Valve CHWR Constant Speed Pump In this type of arrangement. With a two-way valve. These valves control the capacity of each load by varying the amount of water flow through the load device.A. In terms of load control. Before proceeding further. a two-way valve and a three-way valve perform identical functions—they both vary the flow through the load as the load changes. the quantity of water flowing through the load gradually decreases from design flow to no flow. The fundamental difference between the two-way valve and the three-way valve is that as the source or distribution system sees the load. Control valves are commonly used to control loads. the two-way valve provides a variable flow load response and the three-way valve provides a constant flow load response. the quantity of water flowing through the load decreases in proportion to the load and the difference amount is directed through a bypass. Control valves for these applications are two-way (straight-through) and three-way valves. Where multiple zones of control are required.as the load reduces. 38 . On multiple chiller installations. The three-way mixing valve has the same effect on the load as the two way valve . constant water flow through the chillers and load distribution piping circuit is maintained. pumps are required to operate continuously and the sequencing of chillers is dependent on water temperatures. Referring to the foregoing schematic layout. a brief explanation on the operation of a typical chilled water system / valves which is fundamental to the design or analysis of a system. as the valve strokes from full-open to fullclosed. The effect of either valve is to vary the amount of water flowing through the load device. this is a conventional system and is not as energy efficient as the two-way valve systems especially on the pumping side due to constant water circulation in the system. 39 .B. Also. The speed of the chiller pumps is controlled by the differential pressure sensor/transmitter. since they are forced to operate with high radial thrusts. Brief sequence of operation is as follows: The bypass with its control valve and flow meter provides the design flow required through the chillers. Instead of using water temperature as an indicator of demand. the sequencing of chillers is dependent on water flow. Flow meter FM1 measures the actual flow to the chilled water system. the problem with this system is improper control of the bypass valve which does not guarantee proper flow through the chillers and high differential pressures in the control valves on the cooling coils when the system friction subsides at low loads which can cause lifting of the valve stems or wire cutting of the valve seats. maintaining the desired differential pressure (ΔP) across the cooling coils. Further. The system flow is compared with the required flow for the chillers. an almost constant volume system results and the pumping energy remains substantially that required at full system flow and head. This method is not recommended as it’s a wasteful practice because a considerable amount of energy is lost. Single or multiple chillers with constant water flow through chillers and variable water flow through load system: FM-1 CHWS Bypass Line Load Bypass Control Valve Chiller Load P FM-2 2-Way Valve 2-Way Valve Variable Speed Pump CHWR System Controller In this type of arrangement. however the quantity of water flowing through the load distribution piping system decreases in proportion to the load and the difference amount is directed through a bypass pipe that connects the supply and return headers. the actual flow to the system determines the number of chillers that should be in operation. Note: Some designers may consider installing constant speed pumps and utilize pressure relief bypass control valves controlled by a differential pressure sensor/controller to maintain a fixed differential pressure between the supply and return mains of the chilled water system in order to accommodate for the required chiller flow and to achieve some form of variable volume system. which increases the overpressure on the system and also increases the wear on the pumps. This flow meter controls the bypass valve to maintain the desired flow in the bypass based on the set points in the system controller (the valve is positioned by sum of flow meters FM1 and FM2). as all the water must be pumped at a head equal to or greater than the design head. The difference is made up through the bypass and is monitored by flow meter FM2. The chillers are rated in gallons per minute. The pump speed is modulated within a certain range in order to reduce the pumping head and not to alter the water flow rate (the duty flow rate of the pumps remains constant). constant water flow through the chillers is maintained. Each chiller-pump combination operates independently from the remaining chillers and each pump is shutdown when the respective chiller is stopped. Energy is saved because the system head is reduced appreciably when there are light cooling loads on the system and due to cycling of pumps. the pump or pumps are forced to run up the pump head capacity curve. their control valves and the branch piping. performance and trouble-free service. Further. into the return header indicates overcapacity and the chiller-pumps are turned off. maintaining the desired differential pressure (ΔP) across the cooling coils. the generation zone is separated from the transportation or distribution zone. their control valves and the branch piping. Where these requirements are not complied.C. UNIT LOCATION AND INSTALLATION These chillers are designed for outdoor installation and can be installed at ground level or on a suitable rooftop location. Each chiller-pump combination operates independently from the remaining chillers and each pump is shutdown when the respective chiller is stopped. it is essential that the proposed installation location and subsequent installing procedures meet the following requirements: • The most important consideration while deciding upon the location of air cooled chillers is the provision for supply of adequate ambient air to the condenser and removal of heated discharge air from the condenser. higher power consumption and possible eventual failure of equipment. the supply or discharge airflow restrictions or warm air recirculation will cause higher condensing temperatures resulting in poor unit operation. return water is forced through the bypass into the supply header. If greater flow is demanded than that supplied by the chiller-pumps. constant water flow through the chillers is maintained. This pump speed is modulated within a broad range in order to reduce the pumping head and alter the water flow rate based on the changing load conditions. This flow indicates a need for additional chiller capacity and another chiller-pump starts. The sequencing of chillers is dependent on water flow.e. 40 . Single or multiple chillers with constant water flow through chillers and variable water flow through load system (primary/secondary pumping arrangement): CHWS A Variable Speed Secondary Pump Load Load Chiller Flow Sensor P 2-Way Valve 2-Way Valve Constant Speed Primary Pump B CHWR System Controller This system is called a Primary – Secondary System and in this arrangement. the condenser fans are propeller type and are not recommended for use with ductwork or other hindrances in the condenser air stream. In this type of arrangement also. The sequence of operation is similar as the foregoing system with the following explanation: The speed of the secondary chiller pump is controlled by the differential pressure sensor/transmitter. This bypass pipe forms a ‘Hydraulic Coupling’ between the points A – B and is also called as Common Bridge or Decoupling Line. This is accomplished by maintaining sufficient clearances which have been specified in this Catalog around the units and avoiding obstructions in the condenser air discharge area to prevent the possibility of warm air circulation. The primary pumps are constant speed pumps and the design flow rate through the chillers remains constant. however the quantity of water flowing through the load distribution pump/piping system decreases in proportion to the load and the difference amount is directed through a bypass pipe that connects the supply and return headers. In order to achieve good operation.. Excess bypass flow with reference to the set points in the system controller in the opposite direction i. Energy is saved because the system head and water flow rate are reduced on the Secondary Pump when there are partial cooling loads on the system and due to cycling of Primary Pumps. The two types of vibration isolators generally utilized for mounting these units are Neoprene Pads and Spring Isolators. steps must be taken to prevent access to the unit by means of a protective fence. which may cause recirculation or uneven unit airflow. COOLER PIPING CONNECTIONS The following pertinent guidelines are served to ensure satisfactory operation of the units. choose the type of vibration isolators best suited for the application. The roof must be reinforced for supporting the individual point loads at the mounting isolator locations. exhaust vents and sources of airborne chemicals that could attack the condenser coils and steel parts of the unit. It must be checked and ensured that the concrete base is perfectly horizontal and levelled. it is also necessary to consider access requirements based on practical considerations for servicing. This will help to prevent the possibility of vandalism.but an interlock must be wired to the unit control panel (as shown in the wiring diagram) so that the unit can start only upon proof of pump operation. accidental damage or possible harm caused by unauthorized removal of panels or protective guards exposing rotating or high voltage components. The unit shall be mounted on a concrete slab similar to ground installations.• The unit’s longitudinal axis should be parallel to the prevailing wind direction in order to ensure a balanced air flow through the condenser coils. • If the location is an area which is accessible to unauthorized persons. Carefully select the vibration isolators’ models / configuration based on the respective point loads and place each mount in its correct position following the Load Distribution Data and Mounting Drawings provided in this Catalog. Avoid locations where the sound output and air discharge from the units may be objectionable. There should be a straight run of piping of at least five pipe diameters on either side of the flow switch. water must enter from the inlet connection on the cooler and leave from the outlet connection. damage to the unit and difficulty in servicing and maintenance: • Water piping must be connected correctly to the unit i. it must be ensured that the concrete base is stable and does not settle or dislocate upon installation of the unit which can strain the refrigerant lines resulting in leaks and may also cause compressor oil return problems.e. cleaning and replacing large components. follow the recommendations of structural and acoustical consultants. Spring Isolators are recommended for ground level installations which are noisesensitive areas or exposed to wind loads and all roof top installations. • Vibration isolators are necessary for installing these chillers in order to minimize the transmission of vibrations. • Based on the specific project requirements. steam. For locations where significant cross winds are expected.. Refer to the Schematic Mounting Layout drawings provided in the IOM manual of these chillers for further details in this regard. Paddle type flow switches can be obtained from Zamil which are supplied as optional items. When units are installed in an enclosure. For critical installations (extremely noise and vibration sensitive areas). Failure to follow these recommendations may cause improper operation and loss of performance. • The location should be selected for minimum sun exposure and away from hot air sources. FLAT and LEVELLED {within 1/2'' (13 mm) over its length and width} / CONCRETE BASE that extends fully to support the unit. • For ground level installations. Neoprene Pads are recommended for ground level normal installations jobs where vibration isolation is not critical and job costs must be kept to a minimum. It is recommended that the concrete slab is provided with appropriate footings. the enclosure height should not exceed the height of the unit. The carrying or supporting structure should be capable of handling complete operating weight of the unit as given in the Physical Data tables in this Catalog. • The chilled water pump(s) installed in the piping system should discharge directly into the unit cooler. • For rooftop installations. • The clearance requirements prescribed above are necessary to maintain good airflow and provide access for unit operation and maintenance. especially if the roof has been pitched to aid in water removal. • The unit must be installed on a ONE-PIECE. The pump(s) may be controlled external to the unit . The slab should not be connected to the main building foundation to avoid noise and vibration transmission. choose a place with adequate structural strength to safely support the entire operating weight of the unit. • A flow switch must be installed in the field piping at the outlet of the cooler (in horizontal piping) and wired back to the unit control panel using shielded cable. 41 . Consideration should also be given to the possibility of down-drafts caused by adjacent buildings. However. It should be determined prior to installation if any special treatment is required to assure a levelled installation else it could lead to the above mentioned problems. an enclosure of solid or louver type is recommended to prevent wind turbulence interfering with the unit airflow. fitted as close as possible to the liquid inlet connection. preferably of 20 mesh.• Flexible connections suitably selected for the fluid and pressure involved should be provided as mandatory in order to minimize transmission of vibrations to the piping / building as some movement of the unit can be expected during normal operation. Pressure gauges are recommended to check the water pressure before and after the cooler and to determine if any variations occur in the cooler and system.) but as near to the cooler as possible. The bypass can be used during maintenance to isolate the cooler without disrupting flow to other units. The piping and fittings must be separately supported to prevent any loading on the cooler. the taps should be located in the water piping a minimum of 24 inches downstream from any connection (flange etc. each unit should be piped as shown: OUT IN Isolating Valve . • Thermometer and pressure gauge connections should be provided on the inlet and outlet connections of each cooler. 42 . • The cooler must be protected by a strainer. When installing pressure taps to measure the amount of pressure drop across the water side of the cooler. The cooler must not be exposed to flushing velocities or debris released during flushing. It is recommended that a suitably sized bypass and valve arrangement is installed to allow flushing of the piping system.Normally Closed Flow Switch Balancing Valve Connection (flanged / Victaulic) Flow meter Pipe work Strainer Flexible connection Note: For chillers with two coolers. • The following is a suggested piping arrangement at the chiller for single unit installations. Hand shut-off valves are recommended for use in all lines to facilitate servicing. • The system water piping must be flushed thoroughly before connecting to the unit cooler. • Drain and air vent connections should be provided at all low and high points in the piping system to permit complete drainage of the cooler and piping as well as to vent any air in the pipes. For multiple chiller installations. and provided with a means of local isolation. the connecting pipes for entering and leaving water on one cooler must be joined to the corresponding pipes on the other cooler before connecting to the main headers in the system piping.Normally Open Pressure tapping Isolating Valve . chiller model ARY100 operating with a design water flow rate of 205 GPM for a standard air conditioning application would require 100 (Nom. Cap. reduce the rate of change of return water temperature. therefore. d) Laminar flow on the water side due to lower velocities at low loads on a coil is always a concern of the water system designer.) x 3 = 300 Gallons of water in the piping system loop. A number of conditions must be recognized before making the final selection of temperature differential: a) An increase in temperature differential decreases water flow and therefore saves pumping energy. the temperature control can be lost resulting in erratic system operation and excessive compressor cycling. To achieve the aforementioned water volume requirements. There is no one temperature difference for all chilled water systems. Therefore. This tank should be provided on the return water side to the chiller and the tank should be baffled to ensure that there is no stratification and the entering stream thoroughly mixes with the tank water. A careful balance between energy savings and first cost should be made by the designer. The possibility of laminar flow is greater with higher temperature differences. For example. These are the decisions that must be made by the designer for each application and only experienced designers should entertain water temperature differences in excess of 120F on chilled water systems. Laminar flow reduces the heat-transfer rate and should not occur in a coil at any point in its load range. to prevent this effect of a ‘Short Water Loop’ ensure that total volume of water in the piping system loop equals or exceeds 3 Gallons per Nominal Ton of cooling capacity for standard air conditioning applications and 6 Gallons per Nominal Ton of cooling capacity for process cooling jobs where accuracy is vital and applications requiring operation at very low ambient temperatures and low loading conditions. 43 . Temperature differential is the difference between the supply water and the return water temperatures. c) Higher temperature differentials increase the possibilities of loss of temperature difference in coils due to dirt on the air side and chemical deposits on the water side of them. at reduced loads and flows. it may be necessary to install a tank in the piping system loop to increase the volume of water in the system and therefore. they operate with laminar flow. See recommended tank design schematics below: TANK SCHEMATIC SUGGESTIONS ON SYSTEM DESIGN AND PIPING PRACTICES The prospective chilled water system should be designed to the specific requirements of the owner and to achieve the most efficient system possible. Many systems operate inefficiently because of coils that were selected at too low a friction loss through them at design load.CHILLED FLUID VOLUME REQUIREMENT The volume of water in a piping system loop is critical to the smooth and proper operation of a chilled water system. The actual temperature difference that is selected for a specific installation is determined by the cost of the cooling coils for various temperature differences and the effect that higher differences may have on the operating cost of the chillers. Following are some recommendations: • The first decision a designer of a chilled water system must make is the selection of the temperature differential. b) An increase in temperature differential may increase the cost of cooling coils that must operate with a higher mean temperature difference. If sufficient volume of water is not there in the system. Expansion tanks are generally connected to the suction side of the pump . spring loaded. • Distribution pumps should be selected for maximum efficiency at the design condition and within the economic constraints of the project. • Expansion tank should be provided to so that water volume changes can be accommodated. There may be some exceptional cases where parallel pumps are operated at different speeds. Pump discharge check valves should be center guided. b) Arrange the piping so that all chillers receive the same return water temperature.g.. These devices are listed here: a) Three-way temperature control valves b) Balancing valves. • Differential pressure control (bypass) valves should never be installed at the pump discharges. • Coil control valves and their actuators should be sized to ensure that they can operate at all loads on the system without lifting the valve head off the valve seat. c) Ensure that the required design water flow through the coolers is always maintained. The second step in this process is to ensure that the differential is maintained after the system is commissioned. It tells the operator just how good a job the control system and coils are doing in converting energy from the chillers to the air or water systems that are cooling the building. Pump sequencing should achieve maximum possible system efficiency. disc type check valves and should be sized so that the check valve is full open at design flow rate. • Circuiting Chilled water to Multiple Chillers : There are fundamentals for the circuiting of chillers that should not be violated in order to achieve maximum efficiency. This is such a basic criterion that it should be addressed early in the design of a chilled water system. Variable speed pumps should be controlled so that pumps operating in parallel never have more than one percent difference in actual operating speed.• Control of Return Water Temperature: Return water temperature is one of the most important operating values for a chilled water system. 44 . • Check valves should be provided in pump discharges when pumps are operating in parallel. Some of these are: a) Design the piping arrangement so that energy consumption of chillers is not increased. fittings and valves. Mixing of constant and variable speed pumps in parallel operation is wrong and leads to disastrous results. • Pumps in parallel must always operate at the same speed. manual or automatic c) Pressure-reducing or pressure-regulating valves • The piping should be designed without a) Reducing flanges or threaded reducing couplings b) Bullhead connections (e. it is better to use pumps of the same size when operating them in parallel. but only experienced designers should make evaluations for such a proposed operation. • The water system should be configured to distribute the water efficiently with a minimum use of energy-wasting devices. Generally this will require the check valve to be one pipe size smaller than the connecting piping. Distribution pumps should be added and subtracted to avoid operation of pumps at points of high thrust and poor efficiency. The proper method of controlling return temperature is through the correct selection of control valves and cooling coils. Also.lowest pressure point. In conclusion. one of the designer’s most important tasks is the selection of a sound temperature differential that will provide maximum possible system efficiency. two streams connected to the run connections of a tee with the discharge on the branch of the tee) • The friction for the piping should be calculated for all pipe runs. • Cooling coils should be selected with a high enough water velocity in the tubes to avoid laminar flow throughout the normal load range imposed on the coils. Care must be taken to avoid damage to the coils during handling.RIGGING INSTRUCTIONS ATTENTION TO RIGGERS Hook rigging sling thru holes in base rail.
