NOTE
The noise emissions of the heat pumps
must be taken into account in the respective
installation plans for air/water heat pumps.
The respective regional regulations must be
observed.
Unpacking
1.
Remove plastic films. Ensure that you do not dam
-
age the unit.
2. Dispose of the transport and packaging material
in an environmentally friendly way and in accord-
ance with local regulations.
Set up the unit
“Installation plans“, from page 24
1. Set up the unit so that the operating side is acces-
sible at all times.
2. Align the unit horizontally, remove the collision
protection (wooden strips on the base) and screw
on the four base panels with countersunk screws
(supplied).

7 Installation of hydraulic system
►
Flush the heating circuit thoroughly before con-
necting it to the heating system.
IMPORTANT
Damage to the copper pipes due to unacceptable
loading!
►
Secure all connections against twisting.
Connect the unit to the heating circuit according
to the hydraulic diagram for the respective model.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned.
The free pressing of the recirculating pump pro-
duces at least the minimum throughput required
for the unit type (
“Technical data / scope of
supply“, page 20).
The hydraulic system must be equipped with a
buffer tank, the required volume of which depends
on your unit model.
“Technical data / scope of supply”, page 20
The pipes for the heating are fixed to the wall or
ceiling via a fixed point
.
1.
Install shut-off devices for the hot water outflow
(forward flow) and hot water inflow (return flow) on
the heat pump side.
NOTE
During installation of the shut-off devices, the
liquefier of the heat pump can be rinsed, if
necessary.
Positioining of the hydraulic connections:
“Dimensional drawings“, from page 22
2. Connect the unit to the pipes of the heating circuit
via vibration decouplers. They must be installed
in order to prevent damage from vibrations to the
pipes.
NOTE
If an existing system is being replaced, the
old vibration decoupling may not be reused.
Vibration decouplers are available as acces-
sories.
3. Insert a vent at the highest point of the heating cir-
cuit.
4. Ensure that the working overpressures (
“Tech-
nical data / scope of supply”, page 20) are not
exceeded.
