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

legislation must be fitted with low-loss headers.

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 topping up

must be treated with appropriate treatment systems.

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

the drawing.

If the outside air temperature is less than 0°C, the conden-

sate drained from the collection pan may 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.
