Recommendations
Important
The thermodynamic water heater is intended to
be permanently connected to the domestic water
mains network.
Important
Respect the minimum and maximum water inlet
pressure to ensure correct operation of the
domestic hot water tank: refer to the chapter
Technical Specifications.
Caution
The pressure limiter device must be regularly
operated in order to remove limescale deposits
and ensure that it is not blocked.
A pressure reducer (not provided) is necessary
when the supply pressure exceeds 80% of the
calibration of the safety valve or safety unit and
it must be located upstream of the appliance.
As water may flow out of the discharge pipe on
the pressure limiter device, this latter must be
kept clear and open to the air.
Connect the pressure limiter device to a drain
pipe, kept open to the air, in a frost-free
environment, and at a continuous downward
gradient.
Caution
Draining the domestic hot water tank:
1. Shut off the domestic cold water inlet.
2. Open a hot water tap in the installation.
3. Open a valve on the safety unit.
4. When the water stops flowing, the domestic
hot water tank has been drained.
Caution
Install the thermodynamic water heater in a frost-
free environment.
