Installation and Service instructionsfor heating engineers Vitosolic 200 Electronic temperature differential control unit for solar heating systems See "Applicability" on the last page. VITOSOLIC 200 5862 491 GB 9/2003 Please keep safe General information Safety instructions Please follow these safety instructions closely to prevent accidents and material losses. Safety regulations Installation, commissioning, inspection, maintenance and repairs must only be carried out by a competent person (heating engineer/refrigeration specialist/installation contractor). Observe all current safety regulations as defined by DIN, DIN EN, DVGW and VDE (or local regulations). See also the safety instructions sheet in the Vitotec Technical Guide folder. Before working on the equipment/ heating system/solar heating system, isolate its mains electrical supply (e.g. by removing a separate mains fuse or by means of a mains electrical isolator) and safeguard against unauthorised reconnection. Earthing/lightning protection of the solar heating system Install an electrical conductor on the pipework system of the solar circuit in the lower part of the building, to comply with VDE or local regulations. Connection of the collector system to a new or existing lightning protection facility or the provision of local earthing should only be carried out by authorised personnel, who must take into account the conditions applicable on site. Repair work It is not permitted to carry out repairs on parts that fulfil a safety function. Use only original Viessmann spare parts, or equivalent parts that have been approved by Viessmann. Commissioning The initial start-up must be carried out by the system installer or a designated commissioning engineer. All actual values should be recorded in a commissioning/service report. Instructing the system user The system installer must hand the operating instructions to the system user and instruct him/her in the operation of the system. ¨ Safety instruction In this instruction manual, this heading denotes information which must be observed to prevent accidents and material losses. ¨ This symbol denotes information which must be observed to prevent material losses. 2 5862 491 GB Index Index System designs General notes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
