50TJ016-032S Side DischargeSingle-Package Rooftop Units 50/60 Hz 15 to 30 Nominal Tons Product Data The 50TJ-S series is a special side discharge version packaged unit with capacities of 15-30 Tons. This unit can be placed on the side of a building with direct ducts to and from conditioned space, or can be placed on the roof, without a roof curb, and simple Ductwork. High Efficiency Rooftop Units with: • Dual, electrically and mechanically independent refrigerant circuits • Scroll compressors on each circuit • TXV refrigerant metering devices • Non-corrosive, sloped condensate drain pans meet ASHRAE 62-99 (IAQ) • One-inch return air filters • Electric heat (FIOP) Special Standard Features • Double skin construction. • Pre-coated fin condenser coil, for extra corrosion protection. • High Efficiency, High Static Blower. Features/Benefits Every compact one-piece unit arrives fully assembled, charged, tested, and ready to run. Durable, dependable construction Designed for durability in any climate, the weather-resistant cabinets are constructed of galvanized steel, bonderized, and all exterior panels are coated with a pre-painted baked enamel finish. The paint finish is nonchalking, and is capable of withstanding ASTM (American Society for Testing and Materials) B117 500hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for the entire unit. Totally enclosed condenser-fan motor and permanently lubricated bearings provide additional unit dependability. 50TJSD-05 PD C 2008 Easy installation 50TJ All units feature base rail design with forklift slots and rigging holes for easier manoeuvring. Durable packaging protects all units during shipment and storage. Convenient side by side openings permit installation very close to the face of buildings, or on roof top. The non-corrosive sloped condensate pan minimizes residual condensate in off cycle. An external, field-supplied P-trap is required. Field-installed electric heaters are available in two convenient capacities 30 kW or 40 kW. Indoor-air quality begins with Carrier rooftops ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) Standard 62. One-in. filters provide for grater partical reductionin the return air. Simple electrical connections Terminal boards, located in the base unit control box, facilitate connections to room thermostat, outdoor thermostat(s) and electric heat. Service panels are quickly removed, permitting easy servicing. Both power and control connections are made on the same side of the unit to simplify installation. In addition, colour-coded wires permit easy tracing and diagnostics.
