Connecting the product

Check that components which have been removed for transport, separately sup-
plied components and components provided by the client are firmly attached.
Check that all locating screws are tight.

7.4.1.1 Connecting the pipes

The protective gas filling of the heat pump must be purged by opening the vent
valves on the suction side before the connection of the pipes.
Establish all pipe connections so that the transmission of thermal expansion and
vibration to the heat pump is limited as far as possible.
Bellows-type expansion joints made of steel, or flexible metal hoses can be used
for refrigerant and oil lines, bellows-type expansion joints made from rubber can
be used for water connections.
All pipe connections are to be fitted with fixed points directly on the heat pump.

Caution!
Take special care with heat pumps that have been subjected to a factory
acceptance test (FAT).
► There are always small residual amounts of NH
► Heat pumps posing a corresponding hazard are identified with a yellow
sign indicating: Warning inert gas filling on refrigerant side: N
with remnants of ammonia (factory test run).
► These heat pumps are filled after the functional run with the operating
amount of oil (labelling on the oil filter with appropriate oil type).
