Hydraulics installation
b
Caution!
Risk of damage caused by residue in the
heating flow and return.
Residue from the pipelines, such as welding
beads, scale, hemp, putty, rust and coarse
dirt, may be deposited in the heat pump
and cause malfunctions.
>
Flush the heating system thoroughly
before connecting the heat pump in
order to remove any possible residue.
b
Caution!
Risk of damage caused by leaks.
Mechanical stress on the supply lines may
cause leaks and, as a result, will cause dam-
age to the heat pump.
>
Avoid mechanical stress on supply lines.
>
Observe the minimum radius of
r = 300 mm for the supplied flexible con-
necting hoses.

Handling flexible connecting hoses
The installation must only be carried out by a qualified
heating engineer.
>
When installing the pipes, pay attention to the measure-
ment and connecting drawings (
¬
Fig. 4.1
and
¬
Fig. 4.2
).
>
During the installation, observe the applicable regula-
tions.
>
Observe the following note about avoiding sound trans-
mission:
To reduce the level of noise to a minimum, thread the
pipes through ceilings and walls with insulation against
structure-borne sound.
Position the pipe brackets to secure the heating circuit and
brine/well water piping so that it is not too close to the heat
pump in order to prevent the connection from being too
rigid.
In each case, install the supplied flexible connecting pipes
to the vibration isolation on the heat pump.
We do not recommend that you use stainless steel corru-
gated pipes because the corrugated shape of the hoses
would result in too great a loss of pressure in the heating
water.
b
Caution!
The unit may not work properly if there
is air in the heating installation.
Air in the heating system leads to impaired
operation and reduces the heating output.
>
Install bleeding valves at suitable loca-
tions in the heating installation.
