General
Indirectly heated stainless steel tank with up to three fixed welded tube heat exchangers. Complete with thermal insulation and cleaning opening or inspection flange (from 750 l). Can be combined with all modern heating systems. Inspection flange can also be used to connect additional heat sources (electric heater, etc.). Made from very high quality molybdenum stainless steel 1.4521 with excellent resistance to corrosion. Installation-friendly construction, equipped with connection for thermometer and temperature sensor/thermostat. (type-dependent).

Safety requirements
Read these instructions carefully before commencing installation. For any additional questions, please consult our customer service department (see contact details).
WARNING: Do not expose the insulation to open fire!
Installation, commissioning and maintenance must be carried out by specialists according to the applicable regulations (including EN 1717, DIN 1988, EN 12828 and VDI 2035, the relevant regulations for local distributors, national legislation and other regulations). The chloride content of the drinking water must be less than 250 ppm. Suitable measures must be taken to protect the tank from damage caused by pressure. Damage that is caused by underpressure (vacuum) is not covered by the warranty. Protective gloves must be worn when cleaning inside the unit. The flange seal must be replaced after cleaning. Furthermore, facilities for the secure collection and drainage of water from the boiler must be provided to avoid water damage.
WARNING
- Hot water may escape from the safety valves or when draining the boiler. Danger – risk of scalding.
- Failure to comply with this instruction may result in damage to the mains water boiler or the stainless steel heat exchanger.

Flow and return connections according to individual system configuration.
Commissioning
-
The entire system must be thoroughly flushed before commissioning. The system may only be set up in frost-free rooms and a surface that is sufficiently able to bear the load of the
completely filled tank. -
Any unused connections must be professionally sealed.
-
A drainage device is to be provided at the cold water inlet. We recommend installing an Airfix membrane expansion vessel to the cold water supply line. Water hammer in the system must be avoided.
-
However, if water hammer is imminent in conjunction with the potable water tank appropriate precautions are to be taken.
-
The Prescor B safety valve must be installed in an easily accessible place as it is subject to regular inspection. The valve must also be equipped with a drain connection (see schematic for the cold water connection).
WARNING: For safety reasons, it may be necessary for water to escape from the blow-off pipe while the system is heating up. Do not shut off or obstruct the blow-off pipe.
- The seal tightness of the system as a whole must be checked under normal operating conditions and during maintenance and, if necessary, the flange couplings must be tightened. Check the safety valve at regular intervals.
- The boiler must be included in the potential equalisation.
Temperature control/gauge
The temperature sensor in the heating control unit and, if applicable, the solar-power controller and/or thermostat sensor must be fitted in the appropriate plunge pipe. The height of the plunge pipe determines the switching point for reheating. The temperature can be read from the thermometer supplied. It is to be fitted on the front of the unit in the G ½” fitting.
Inspection & maintenance
- No liability shall be accepted for damage that is caused by failure to follow the installation and operating instructions.
- The boiler must be installed to allow easy access for maintenance, operation, repairs or replacement. Site preparation and suitability for installation of the vessel are not the responsibility of the manufacturer or the responsible distributor. Furthermore, facilities for the secure drainage of the boiler in the event of any water leakage must be provided to avoid water damage.
- If the local water is highly calciferous, a commercial de-calcifier can be fitted before the potable water part of the system. Natural calcification is not the boiler manufacturer’s responsibility.
- If in doubt please consult the manufacturer.
- Dirt traps are recommended for both mains water and hot water systems. They must be serviced regularly depending on the system conditions.
- Sources of electro-chemical corrosion, such as mixing systems, must be avoided.
Removal
Once cooled, depressurize the system and remove the product from the system. Local legislation must be adhered to when disposing of the various components.
