Safety instructions This hazard symbol precedes all important notes on safety. Please follow these safety instructions closely to prevent possible risk of injury to persons and damage to property. Safety regulations Please observe all relevant safety requirements (GB: British Standards code of practice) (see also the enclosed red sheet headed Important safety information ). In certain countries, solar collectors must be registered or issued with a permit in accordance with national regulations. The entire solar heating system should be installed in accordance with the accepted rules of technology (GB: British Standards codes of practice), observing all relevant accident prevention regulations. Please note: Please read these instructions carefully before commencing with installation and start-up. Failure to observe the installation, operating and service instructions could invalidate the guarantee. The installation instructions for Viessmann accessories (where included in the scope of supply) must be followed when installing the complete system (comprising Viessmann modular system components). We organise regular training courses for installers. Use suitable safety measures to prevent falls, falling objects and roof damage due to insufficient load bearing capacity, e.g. by means of scaffolding, ladders, cable ties etc. Observe the maximum load for the understructure of the building and the distance from the roof edge as required by DIN 1055. Work on the solar heating system Installation, maintenance and repairs must be carried out by a competent person (heating engineer/service contractor). Before work is undertaken on the equipment/heating system/solar heating system, the mains voltage must be switched off (e.g. at the separate fuse or mains electrical isolator switch) and measures taken to prevent it from being switched on again. Potential equalization/lightning protection of the solar heating system An electrically conductive connection of the pipework system of the solar circuit should be implemented in the lower part of the building in accordance with I.E.E. regulations. Connection of the collector system to a new or existing lightning protection facility or the provision of local potential equalization should only be carried out by competent personnel, taking into account the conditions applicable on site. 2

Installation Mounting the collectors Important: Install the collector panel so that the nameplate side of the first and last collector is on the outside (note sticker). If only one collector is to be installed, connect the piping opposite the nameplate side. The connecting pipes must not be damaged or dirty. All plug-in connections (O ring seal) on the collectors may only be lubricated with the special lubricating grease supplied in the connection kit. The connections must not come into contact with conventional oils, greases or other lubricants. Collector connection Spacer fold Sticker Fig. 5 Mounting the collectors 1. Place the first collector on the collector support frames and push up against the spacer fold. 2. Screw the collector to the mounting plates / with clamping bolts, washer and hexagon nut. 3. Insert the connecting pipes as far as they will go into the collector connections.. Position the next collector and carefully push it up against the first collector so that the connecting pipes can be inserted fully into the collector connections (collector must butt up against the spacer fold). 5. Screw on collector as described under point 2. 6. Mount the rest of the collectors as described under points 3 to 5. 7. Remove the sticker from the glass cover. 11

Hydraulic connections Mounting the connection kit (continued) Important: The procedure for installing the clamping ring connection is as follows: Ensure that all pipe ends are rectangular and free from burring. Push the union nut and the clamping ring onto the pipes and moisten thread with a little oil. Push the pipe as far as it will go into the clamping ring connection. First tighten the union nut by hand, then tighten by a 3 / turn with an open-end wrench. Do not use annealed copper pipes on clamping ring connections. 1. Fully insert the connection pipes on the side of the collector panel on which the hydraulic connections are to be installed. 2. Fully insert the stopper on the other side of the collector panel. 3. Screw the profile clips onto the flared couplings, stopper and pipes to secure the stopper and connection pipes.. Mount the clamping ring connection or on the return connection. 6. Screw the sensor well into the tee ; apply countergrip on tee. 7. Screw the strain relief connection into the sensor well. 8. Fully insert the collector temperature sensor into the sensor well and secure with the strain relief connection. 9. Make the connection between the collector panel and the piping of the solar circuit. 5. Mount the clamping ring connection (tee) on the flow connection. 13
Appendix Installation Please refer to the technical guide Solar heating systems for supplementary notes on installation examples and system types. Important! For installation purposes, use red bronze fittings, brass fittings and copper piping. Do not use galvanized pipes, galvanized fittings or graphitized gaskets. Hemp should be used only in conjunction with pressure and temperature-resistant sealants *1. The components used must be resistant to the heat transfer medium (see Service Instructions for composition). The insulation *2 of external piping must be resistant to temperature, UV radiation and to destruction by birds (e.g. through the use of metal sheathing). Caution! Do not stand on the collectors! Do not carry out soldering work at or near the collector! At least one air vent valve should be installed at the highest point of the system. Install an air separator at an accessible point in the piping (e.g. in the flow of the solar circuit, upstream of the inlet to the indirect coil of the domestic hot water cylinder). The system should be equipped with an expansion vessel, safety valve and circulation pump. Use only a diaphragm expansion vessel that is suitable for the application as an expansion vessel. The expansion vessel must be approved to DIN 807 and must be connected via a heat insulating loop. The diaphragms and seals of the expansion vessel and safety valve must be suitable for the heat transfer medium. Please refer to the Service Instructions in order to calculate the inlet pressure of the diaphragm expansion vessel. Fill the solar heating system with Viessmann heat transfer medium Tyfocor-HTL. The blow-off and discharge pipes must be run to an open container capable of accommodating the total capacity of the collectors. The Solar-Divicon is equipped with a safety valve designed for 0 ºC and max. 6 bar. For operation without the Solar-Divicon, use only safety valves rated for 0 ºC and max. 6 bar with a part designation containing the code letters D/G/H, F or H. On smaller solar heating systems with a collector surface area up to 5m 2, Vitocell 300 cylinders with a peripheral heating system and a capacity of 200 litres may also be used as solar storage cylinders for preheating purposes. In this case, the Solar-Divicon must be equipped with a 3 bar safety valve (accessory). The static head should be 7 metres max., the overpressure in the collectors approx. 1 bar and the inlet pressure of the diaphragm expansion vessel approx. 1.5 bar. In such cases, we recommend an expansion vessel with a capacity of 33 litres. To guarantee the satisfactory operation of the solar heating system, install the pipes so that complete venting is assured. The connecting lines must be pressure and temperature-resistant (observe the max. shutdown temperature of the collector). *1 E.g. Viscotex solar paste supplied by Locher, CH-950 Altstätten. *2 E.g. HT/Armaflex (temperature resistant up to 175 ºC) supplied by Armstrong Insulation Products GmbH, Robert-Bosch-Str. 10, *2 D-8153 Münster. 1
