The heat pumps
must be fitted with a filling/top-up sys-
tem connected to the return line and a drain valve in the
lowest part of the system.
Systems containing antifreeze
or covered by specific

The manufacturer is not liable for obstruction, breakage
or noise resulting from the f
ailure to install filters
or
vibration dampers.
Particular types of

For reference values, see the table.
CONDENSATE DRAIN
The unit is fitted with condensate pan; this must be connect-
ed to a drain system to take away the water that forms, see

If the outside air temperature is less than 0°C, the conden-
sate may gradually freeze.
The unit must be supported on a suitable structure or brack-
ets to keep it off the ground, with a frost protection heater fit-
ted on the drain line.
