6.2 Opening indoor unit

The cover must be removed to allow access to the inside of the

NOTE
When removing the unit cover, it must be taken into account
that the length of the connecting cable between the control
panel in the unit cover and the controller on the contact plate
is only 1.5 m. If the device cover can only be placed further
away than this when it has been removed, the plug
connection on the controller or on the control panel must first
be disconnected.
After removing the cover, the electronics area is freely accessi-
ble.
The contact plate contains the power supply connection termi-
nals, heating contactors and the heat pump manager.
CAUTION!
Before switching the electric circuits back on, ensure that the
device has been sealed and live parts cannot be touched.

6.3 Connection on heating side

The heating system connections on the indoor unit have a
1 1/4" flat sealing external thread. A spanner must be used to
firmly grip the transitions when making the connections.
There is a hose sleeve on the safety valve for on-site connection
of a plastic hose. This should be fed into a siphon or outflow.
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc.
CAUTION!
Any accumulation of deposits in the liquefier may cause the
heat pump to completely break down.
Once the heat pump has been connected to the heating sys-
tem, it must be filled, purged and pressure-tested.
