Note Details identified by the word "Note" con- tain additional information. Target group These instructions are exclusively designed for qualified personnel. ■Work on electrical equipment must only be carried out by a qualified elec- trician. ■The system must be commissioned by the system installer or a qualified per- son authorised by the installer. Regulations Observe the following when working on this system ■all legal instructions regarding the pre- vention of accidents, ■all legal instructions regarding envi- ronmental protection, ■the Code of Practice of relevant trade associations. ■all current safety regulations as defined by DIN, EN, DVGW, VDE and all locally applicable standards Working on the system ■Isolate the system from the power sup- ply and check that it is no longer 'live', e.g. by removing a separate fuse or by means of a main isolator. ■Safeguard the system against unau- thorised reconnection. ! Please note Electronic modules can be dam- aged by electrostatic dis- charges. Touch earthed objects, such as heating or water pipes, to dis- charge static loads. Repair work ! Please note Repairing components that fulfil a safety function can compromise the safe operation of your heating system. Replace faulty components only with original Viessmann spare parts.

wearing parts ! Please note Spare and wearing parts that have not been tested together with the heating system can com- promise its function. Installing non-authorised components and non-approved modifications or conversions can compromise safety and may invalidate our warranty. For replacements, use only orig- inal spare parts supplied or approved by Viessmann. Safety instructions Safety instructions (cont.) 5692 808 GB

■Never drain the system with a vacuum pump. ■Check the system for leaks: The collector in its cold state must be subject to a positive pressure of at least 1.0 bar. At a static head of 10 m, this would result in a system pressure of 2.0 bar. 1. Leave collectors covered or cover if necessary. Open any installed shut-off gates or valves by hand. Open the non-return valves when using a Solar-Divicon: Flow/return: Turn the thermometer clockwise through 45°. 2. Close the shut-off valve of the fill valve and open the drain valve. 3. Flush the system via the return con- nections. Fill and flush the system with heat transfer medium via the fill valve. Flush using a high speed pump over an open container and continue until no air remains in the collector system. Correct commissioning can only be guaranteed with a system that is completely free of air. Now close the drain valves on the fill valve, open the shut-off valve and check the system for leaks. Observe the permissible operating pressure. Pressure must not drop for at least 30 minutes. Notes ■A heat transfer medium containing gly- col can deteriorate if it is exposed to temperatures above 170 °C for pro- longed periods (stagnation). Temperatures in excess of 200 °C result in a slow thermal breakdown of the 1,2-propylene glycol that can be recognised by a darkening of the heat transfer medium. Furthermore, it can result in the solar circuit suffering from sludge and hard deposits, particularly in conjunction with other contaminants (cinder, swarf) and air. ■Ensure that the system is correctly flushed, filled and ventilated after installation. ■After filling the system with the heat transfer medium, ensure that the sys- tem is fully vented and that heat is transferred inside the system. ■Blow-off and drain lines must termi- nate in an open container, that is capa- ble of collecting the full collector con- tent.

1. Drain the system. For this, close the cap valve on the expansion vessel (if installed) and reduce the pressure. 2. If the pre-charge pressure of the expansion vessel is lower than the set value, top up with nitrogen until the pre-charge pressure equals the set value. Static head (top edge of collector to expansion vessel): ........... m Set pre-charge pressure of the expansion vessel: 0.7 bar + 0.1 x static head in m 0.7 bar + 0.1 x ......... m = ........ bar 3. Top-up heat transfer medium until the system pressure is 0.3 to 0.5 bar higher than the set pre-charge pres- sure of the expansion vessel (create a safety water seal in the expansion vessel). The safety water seal should be 0.005 x liquid content of the complete system, but no less than 3 litres. Liquid content of the system = con- tent of pipes + content of collectors + content of the indirect coil of the DHW cylinder and safety water seal for the expansion vessel. Checking the electrical connections Check the tightness of the electrical plug-in connectors and cable grommets; check cables for damage. Starting the system Observe operating instructions of instal- led components. Commissioning, inspection, maintenance Further details regarding the individual steps (cont.) 5692 808 GB

1. Open the air vent valve. Vent the circulation pumps. For this, adjust the circulation pumps to their maximum speed, switching the pump ON and OFF several times (a venti- lated pump runs almost silently) through a relay test (manual opera- tion). Repeat the ventilation process until the float in the flow meter of the Solar-Divicon holds a constant posi- tion when the pump is running (high- est pump rate). Note Air can be recognised in the flow rate indicator (float moves). 2. Set the required flow rate via the pump rate of the circulation pump (see following tables for approximate set values). Check the value underneath the float. 3. Repeat the venting process after the system has been operational for sev- eral days. Note If the system pressure drops, top-up the heat transfer medium in the cold state and vent again. 4. Always shut off the air vent valve after venting.

Please note To prevent equipment damage, cover the collectors before com- mencing any work on the compo- nents of the solar thermal sys- tem. Mixing the heat transfer medium with water reduces the frost and corrosion protection. Only flush the system with the specified heat transfer medium. Never mix "Tyfocor LS" with other heat transfer media. Electrically isolate the system (e.g. at a separate MCB/fuse or the main isolator) and safeguard against unauthorised reconnection.

the heat transfer medium Check the frost protection temperature of the "Tyfocor LS" heat transfer medium with a Viessmann antifreeze tester or the manual refractometer in the solar service case (accessory). Check the pH value using the pH strip in the solar service case (accessory). Solar service case operating instructions Checking the thermal insulation of the pipes Check the thermal insulation of the pipes for positioning and damage and adjust if required. Replace any damaged parts. Note The thermal insulation of external pipes must be resistant to temperature and UV rays. The insulation must be protected against attack from small animals and birds (e.g. metal sheath).
