INSTALLATION OF THE HYDRAULIC CONNECTIONS
ATTENTION
The heat source system must be constructed
according to the specifications of the planning
manual.
Planning manual and “Hydraulic connection”
instructions.
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.
Overview “Technical data / scope of delivery”,
“Heat source” and “Heating circuit” sections.
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.
ATTENTION
During connection of components, secure con-
nections 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.
CONNECTIONS ON THE MODULE BOX
1 Heat source inlet
2 Heat source outlet
3 Electric/sensor lines
4 Heating circuit outlet (forward flow)
5 Heating circuit inlet (return flow)
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.
Proceed as follows:
