4.4.1 Cooling
operation
For cooling operation, all system components
(pipework, fittings) must be insulated against
condensate forming by means od suitable insu-
lating materials. This holds especially for the
flow pipework from the heat pump to the buffer
tank/distributor.

Heat source connection
4.5.1 Wall
conduit
Conduits through external walls are to be exe-
cuted with lined pipework. These are to be laid
with a slight slope from inside to out!
This is the only way to guarantee that conden-
sate/rain water gathering can be properly dis-
posed of through the house drainage system,
and no dampness can get into the brickwork. It
is also very important that the feed pipe on the
outside of the building is surrounded by gravel
and is bevelled from the top to the bottom

This hinders the water from entering the build-
ing in the event of heavy rainfall. After place-
ment, the pipe should be sealed with foam or if
necessary a special sealing compound.
4.5.2 Refrigerant
pipework
The refrigerant pipework should always be po-
sitioned to the side of the heat pump (left or
right). Connections to rear should only be car-
ried out in exceptional cases, as the connection
is made considerably more difficult!
4.5.3
Leak check
The leak check is to be performed and docu-
mented by OCHSNER Customer Service dur-
ing the commissioning process.
4.5.4 Insulation
All exposed refrigeration lines are to be well
insulated to prevent build-up of condensation
and thermal losses.
Insulation installed underground
must be a closed-pore material. The
insulation properties of the insulation
will otherwise be negatively influ-
enced
