Installations containing antifreeze
or covered by
specific legislation must be fitted with hydraulic discon-
nectors.
The manufacturer is not liable for obstruction,
breakage or noise resulting from the failure to install
filters or vibration dampers.
Particular types of water used for filling
or top-
ping up must be treated with appropriate treatment
systems. For reference values, see the table.

SIZE AND POSITION OF CONNECTIONS
FILLING THE INSTALLATION
- Remove the inspection panel.
- Before filling, check that the installation drain valve is
closed.
- Open all installation, appliance and terminal air vents.
- Open the gate valves.
- Begin filling, slowly opening the water filling cock inside
the unit.
- When water begins to leak out of the terminal air vent
valves, close them and continue filling until the pressure
gauge indicates a pressure of 1.5 bar.
- Replace the inspection panel
The installation must be filled t
o a pressure of
between 1 and 2 bar.
It is recommended
that this operation be repeat-
ed after the unit has been operating for a number
of hours. The pressure of the installation should be
checked regularly and if it drops below 1 bar, the
water content should be topped-up.
Check
the hydraulic tightness of joints.
EMPTYING THE INSTALLATION
- Remove the inspection panel.
- Before emptying, place the mains switch in the “off” posi-
tion.
- Make sure the installation fill/top-up water cock is
closed.
- Open all the installation air vent valves, the drain cock and
the terminals.
- Replace the inspection panel
If the fluid in the circuit contains antifreeze,
it
should not be allowed to drain freely as it is pollutant. It
should be collected for possible reuse. When draining
after heat pump operation, take care as the water may be
hot (up to 50°).
