Installation instructions, domestic hot water storage
1. Provid, where necessary, a pressure reducer for the entering water.
2. Be provided with a safety valve set according to what is reported on the “technical dates” label applied to the boiler.
3. Be provided with an expansion tank proportioned to the boiler’s dimensions (you are advise to let the circulation be made by a thermo
technician).
4. Before starting it you are invited to check the clamping of all the screws of the flange.
5. Each year an internal cleaning must be executed.
6. In order to avoid corrosion the anodes must be inspected after each 12 months; however, where the water is particularly aggressive the
inspections must be reduced to each 6 months. If the anode is consumed it must be substituted.
The used materials can be subdued to deformations caused by temperature oscillations; we recommend you to store them in covered rooms
and mild temperatures (15-20°C).

2/4kW Electric heater
The resistance R can operate simultaneously to the compressor.
For example:
•
antilegionella scheduling
•
BT7 < (setpoint ACS - 19°C)
Immersion heater
Regulating thermostat 30-70°C
Safety thermostat 90°C
The heater should only be used to heat drinking water with a hardness between 7° f to 25° f in according to legislation.
In the case of higher water hardness it is advisable to install a water softener in the system.
The heater must not operate in open air but always completely submerged.
The manufacturer declines all responsibility for damages caused by the heater dry operating.
