Assembly of the Hydraulic
Connections
DANGER!
Danger of fatal injury due to electric
current!
Before opening the unit, disconnect the
system from the power supply and secure
it from being switched back on!
CAUTION.
The heat source system must be designed
corresponding to the specications of the
planning manual.
Heat pump guide and “Hydraulic connection” in-
structions.
NOTICE:
Check to make sure that the diameters
and lengths of the pipes for the heating
circuit and for the heat source are suf-
ciently dimensioned.
NOTICE:
Circulating pumps must be multi-stage.
They must be able to deliver at least the
minimum ow rate required for your mod-
el.
Overview “Technical data/scope of delivery”,
“Heat source “ and “Heat circuit” section.
CAUTION.
The hydraulic system must be equipped
with a buffer tank, the required volume of
which depends on the model of your unit.
CAUTION.
When installing the connections, always
secure the connections on the unit from
twisting, in order to prevent damage to
the copper pipes in the interior of the
unit.
Proceed as follows:
Mount shutoff devices on the heating circuit…
Mount shutoff devices on the heat source…
NOTE.
The evaporator and liqueer of the heat
pump can be rinsed, if necessary, when
mounting the shutoff devices.
CAUTION!
Only have the condenser rinsed by cus-
tomer service personnel authorised by the
manufacturer
.
Position a ventilator at the highest point of the heat
source in the heat source outlet…
You need to make the connection to the xed pipe-
work via the compensators (accessories)…
The compensators serve for vibration isolation…
We recommend mounting a dirt lter (screen size
0.9 mm) at the heat source inlet connection (re-
turn)…
The hot water and heat source connections are
marked correspondingly on the device.
For the positioning of the connections, see di-
mensional diagram for the relevant device type.
Screw the compensators onto the connections on
the unit until they bear against the rubber gasket…
