1 Installation instructions for heating engineers Vitosol 200 Type D10, D20 and D30 Direct flow vacuum tube collector VITOSOL 200 4/2004

2 Safety instructions Please follow these safety instructions closely to prevent accidents and material losses. Safety regulations Installation, initial start up, inspection, maintenance and repairs must only be carried out by a competent person (heating engineer/installation contractor). Observe all current safety regulations as defined by DIN, EN, DVGW and VDE or locally applicable standards. See also the safety instructions sheet in the Vitotec technical documentation 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. Safety instruction Denotes information which must be observed to prevent accidents and material losses. Observe maximum load and distance from roof edge for the substructure installed on the roof to DIN

Push the union nut and the locking ring onto the pipe and lightly lubricate the threads with oil. Push the pipe into the compression fitting as far as it will go. Initially turn the union nut by hand, then tighten with an open ended spanner by a further ¾ turn. Do not use annealed copper pipes with compression fittings. 1. Insert the plug or plug with air vent valve until they bottom out. Please note Use the plug with air vent valve, if the water connections from the collector array are routed downwards. 2. Insert the connecting pipes until they bottom out. 3. Fit the profile clips onto the flared coupling, plugs and pipes to secure the assembly. 4. Thread the locking ring fittings onto the connecting pipe. 5. Insert into the support sleeves of the solar circuit pipes.

49 Water connections (cont.) Safety instruction Only rotate the vacuum tubes with locking ring released. Otherwise there is a risk of breakage. 1. Open the connection housing and remove the thermal insulation mat. 2. Remove the protective cap from the vacuum tubes. 3. Click the vacuum tubes into the tube holders on the mounting rails until they bottom out inside the coupling. Ensure no part of the thermal insulation is pinched in the process. 4. For roofs with deviations from due south: Adjust the angle of inclination of the vacuum tube absorber using the template supplied by turning the tubes around their own axis (coated side of the absorber oriented towards the sun). 6. Secure the vacuum tubes with the retaining rubber. 7. Fit the collector temperature sensor in the connection housing position that is furthest west. Insert the sensor into the holder until it bottoms out. Route the sensor lead in the recess of the thermal insulation and secure with adhesive tape. 8. Secure the sensor with PG thread onto the casing. 9. Carefully position the thermal insulation mat and close the connection housing. 5. Initially tighten the locking ring fitting by hand. For this, hold the soldered hexagon nut with an open ended spanner SW 17. Then tighten the locking ring fitting by 1½ turns. 49

50 Installation Safety instruction Use only gunmetal and brass fittings and copper pipes for the installation. Never use galvanized pipes, galvanized fittings or graphitised gaskets. Use hemp only in conjunction with pressure and temperature resistant sealants (e.g. Viscotex Solarpaste, Locher, CH 9450 Altstätten). Never step onto solar panels. Never solder near or on the collector.

51 Installation (cont.) 1. Route pipes so that they can be completely vented. Install at least one air vent valve at the highest point of the system. Install an air separator at an accessible point in the pipework (see fig. on page 50). 2. Equip the system to EN with expansion vessel, safety valve and circulation pump. 3. The expansion vessel must be approved to DIN 4807, and must be arranged with a heat insulating loop. The diaphragms and seals of the expansion vessel and the safety valve must be suitable for the process medium. 4. When operating without Solar Divicon, use only safety valves designed for a max. of 120 ºC and 6 bar bearing the marking "S" (solar) as part of the component identification. 5. Make all unions pressure and temperature resistant (observe the max. standby temperature of the solar panel). For commissioning of the solar heating system, see service instructions. For the calculation of the inlet pressure, see the service instructions. 51
