note.
Check to make sure that the diameters
and lengths of the pipes for the heating
circuit and the heat source are sufficiently
dimensioned. the free compression of the
circulating pumps must be able to deliver
at least the minimum flow rate required
for your model.

Danger!
risk of fatal injury due to electric shock!
Before opening the unit, disconnect the
system from the power supply and secure
it from being switched back on!
proceed as follows:
Install shut-off devices at the heating circuit.
Install shut-off devices at the heat source.
note.
During installation of the shut-off devices,
the evaporator and liquefier of the heat
pump can be flushed, if necessary.
CautIon!
the condenser may be flushed only by
customer service personnel authorised by
the manufacture.
CautIon!
During connection of components, secure
connections on the module box and on the
compact unit against twisting in order to
prevent damage to the copper pipes in the
inside of the module box and the compact
unit.
place a bleeder at the highest point of the heat
source in the heat source outlet…
If necessary, place a bleeder at the highest point of
the heat source in the heat source inlet…
place a bleeder at the highest point of the heating
circuit in the heating circuit outlet (forward flow)…
If necessary, place a bleeder at the highest point of
the heating circuit in the heating circuit inlet (return
flow)…
We recommend installing a contamination filter
(screen size 0.9 mm) on the heat source inlet
connection.

ConneCting the module box to the heating
CirCuit
The vibration decouplers for the connection of the
heating circuit to the module box are pre-mounted in
the unit. They are located to the right of the module box
after it has been inserted.
