Installation! Please note Incorrect installation can lead to collector damage. Use only gunmetal and brass fittings and copper pipes for the installation. Use hemp only in conjunction with pressure and temperature-resistant sealants (e.g. Viscotex Solarpaste from Locher, CH-9450 Altstätten). Never step onto solar panels. Never solder near or on the collector. 51

52 Installation (cont.) A Collector B Solar-Divicon C Collecting tank D Expansion vessel E Pre-cooling vessel (if required) F Shut-off valve G Fill set H Manual solar fill pump K Fill valve (F, G, H) L Drain M Air separator N DHW cylinder O Solar control unit P Air vent valve 52

53 Installation (cont.) 1. Route pipes so that they can be completely vented. Install at least oneairventvalvewithshut-off facility at the highest point of the system. Install an air separator at an accessible point in the pipework (see illustration on page 52). 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. For the calculation of the inlet pressure, see the "Vitosol" service instructions. 4. When operating without Solar-Divicon, only use safety valves designed for 120 C and a maximum of 6 bar which carry the "S" (Solar) designation. 5. Make connections pressure and temperature-resistant (observe the max. idle temperature of the collector). Commissioning and adjustment For commissioning of the solar heating system, see "Vitosol" service instructions. 53
