Work on gas equipment must only be carried out by a qualified gas fitter. Work on electrical equipment must only be carried out by a qualified electrician. The system must be commissioned by the system installer or a qualified person authorised by the installer. Regulations Observe the following when working on this system all legal instructions regarding the prevention of accidents, all legal instructions regarding environmental protection, the Code of Practice of relevant trade associations. all current safety regulations as defined by DIN, EN, DVGW, TRGI, TRF, VDE and all locally applicable standards. If you smell gas Danger Escaping gas can lead to explosions which may lead to serious injury. Do not smoke. Prevent naked flames and sparks. Never switch lights or electrical appliances ON or OFF. Close the gas shut-off valve. Open windows and doors. Remove all people from the danger zone. Notify your gas or electricity supplier from outside the building. Shut off the electricity supply to the building from a safe place (outside the building). If you smell flue gas Danger Flue gas can lead to life-threatening poisoning. Shut down the heating system. Ventilate the boiler room. Close all doors in the living space. 2

3 Safety instructions Safety instructions (cont.) Working on the system When using gas as fuel, also close the main gas shut-off valve and safeguard against unauthorised reopening. Isolate the system from the power supply 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 unauthorised reconnection. Please note! Electronic modules can be damaged by electrostatic discharges. Touch earthed objects, such as heating or water pipes, to discharge static loads. Ancillary components, spare and wearing parts Please note! Spare and wearing parts that have not been tested together with the heating system can compromise its function. Installing non-authorised components and non-approved modifications or conversions can compromise safety and may invalidate our warranty. For replacements, use only original spare parts supplied or approved by Viessmann. 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. 3

18 Installation sequence Connecting the DHW side For connecting on the DHW side, observe DIN 1988 and DIN Connect all pipework with detachable fittings. Seal connections that are not required with red brass caps. Equip the DHW circulation pipe with a DHW circulation pump, check valve and time switch. Connect the DHW circulation pump either to the control unit or the separate time switch Permiss. temperature: 95 C Permiss. operating pressure: 10 bar Test pressure: 16 bar WW ZP KW Z SIV AV MA EV EV DMV RV2 MAG-W DFR RV1 AV AV TF AV KW EV A Spring-loaded check valve B Visible discharge pipe outlet AV Shut-off valve DFR Flow regulating valve DMV Pressure reducer EV Drain KW Cold water MA Pressure gauge connection MAG-W Diaphragm expansion vessel (suitable for DHW) RV1 RV2 SIV TF WW Z ZP Non-return valve Non-return valve/pipe separator Safety valve Drinking water filter DHW DHW circulation pipe DHW circulation pump 18

19 Installation sequence Connecting the DHW side (cont.) Information regarding the safety valve The system must be equipped with a type-tested diaphragm safety valve as protection against overpressure. Permiss. operating pressure: 10 bar. The connection diameter of the safety valve must be R ¾ (DN 20). Consequently, the max. permissible heat input would be 150 kw. If the heat input of the Vitocell exceeds 150 kw, select a larger safety valve that is able to cope with the respective heat input (see DIN , issue 3/88, section 6.3.1). Install the safety valve in the cold water pipe. It must not be able to be isolated from the DHW cylinder. The pipework between the safety valve and the DHW cylinder must not be restricted in any way. The safety valve discharge pipe must not be able to be closed. Expelled water should be safely and visibly drained into a sewer. Place a sign close to the safety valve discharge pipe or on the safety valve itself with the following inscription: "For safety reasons, water may be discharged from the discharge pipe during heating. Never seal off!" Install the safety valve above the top edge of the DHW cylinder. Installation Connecting the heating water side Adjust the thermostat and high limit safety cut-out so that the DHW temperature in the cylinder never exceeds 95 ºC. Connect all pipework with detachable fittings. Permissible temperatures on the solar side: 140 C on the heating water side: 110 C Permissible operating pressure on the solar side: 10 bar on the heating water side: 3 bar 1. Install the flow pipes with an incline and fit an air vent valve at the highest point. 2. Install control equipment that ensures the permissible temperatures on the heating side are maintained. 3. Install an additional type-tested high limit safety cut-out, if none has been installed so far in the system. For this, use a twin thermostat (temperature limiter and high limit safety cut-out). Test pressure on the solar side: on the heating water side: 16 bar 4.8 bar 4. Seal all unused connections with plugs or caps. 19

22 Commissioning, inspection, maintenance Steps - commissioning, inspection and maintenance For further information regarding the individual steps, see the page indicated Commissioning steps Inspection steps Maintenance steps Page 1. Filling the DHW cylinder Inspection and maintenance Shutting down the system 4. Cleaning the inside of the DHW cylinder Checking connections on the water side for leaks 6. Instructing the system user

23 Further details regarding the individual steps Filling the DHW cylinder Commissioning, inspection, maintenance 1. Fill the DHW cylinder from the DHW side. Note Initially fill the cylinder on the DHW side, then on the heating water side. If the DHW side of your cylinder cannot be filled yet, but you want to commission your heating system, then you can operate your cylinder with a pressure of 2.5 bar on the heating water side. 2. Check the fittings on the heating water and DHW side for leaks and retighten if required. 3. Check the function of the safety valves according to manufacturer's instructions. Operation without DHW heating: Operating instructions for the heating system Note The solar coils are vented via the solar flow. Collect excess solar heat transfer medium with a flexible hose above the air vent plug and restart the system. Alternatively: Service instructions for the solar thermal system Inspection and maintenance DIN 1988 requires a visual inspection and (if required) cleaning no later than two years after commissioning of the cylinder and thereafter according to requirements. Service 23

24 Commissioning, inspection, maintenance Further details regarding the individual steps (cont.) Cleaning the inside of the DHW cylinder 1. Drain the cylinder from the DHW side. 2. Disconnect the cylinder on the DHW side from the pipework to prevent cleaning agents and contaminants entering the pipework. 3. You can also carry out cleaning on the DHW side with chemical cleaning agents.! Please note Never use cleaning agents containing hydrochloric acid, to prevent material losses. 4. Fully drain any cleaning agent. 5. Thoroughly flush the indirect coil on the DHW side after cleaning. 6. Reconnect the cylinder to the pipework. 7. Fill the cylinder from the DHW side. Danger Cleaning agent residues can lead to poisoning. Always observe the details provided by the manufacturer of the cleaning agent. Instructing the system user The installer must instruct the user in the operation of the system. 24
