Basic Device
The basic device consists of a ready-to-use heat pump for indoor
installation in a compact design. In addition to the control panel
with integral controller, the device is already equipped with all of
the most important components of the heating circuit and the
brine circuit:
Expansion vessel
Circulating pumps
Pressure relief valves
Manometer
Overflow valve (heating circuit)
The refrigerating cycle contains the refrigerant R407C. R407C
refrigerant is CFC-free, non-ozone depleting and non-combusti-
ble.
All components required for the operation of the heat pump are
located on the control panel. The power feed for the load current
and the control current must be installed by the customer.
The customer must provide both the collector and the brine cir-
cuit manifold.

Accessories
4.1 Brine circuit manifold
The brine circuit manifold merges the individual collector loops of
the heat source system into a single main pipe which is con-
nected to the heat pump. Integrated ball valves allow the individ-
ual brine circuits to be shut off for de-aeration purposes.
4.2 Brine controller
If required by the authorities, a low-pressure brine controller can
be installed in the device. In this case, the connection located up-
stream from the brine expansion vessel provided for this purpose
is to be used.

Transport
A lift truck is suited for transporting the unit on a level surface.
Carrying straps may be used if the heat pump needs to be trans-
ported on an uneven surface or carried up or down stairs. These
straps can be passed directly underneath the wooden pallet.
ATTENTION!
The heat pump is not secured to the wooden pallet.
ATTENTION!
The heat pump must not be tilted more than 45° (in any direction).
Use the holes provided in the sides of the frame to lift the unit
without the pallet. The side panel assemblies must be removed
for this purpose. Any commercially available length of pipe can
be used as a carrying aid.
ATTENTION!
Do not use the holes in the panel assemblies for lifting the device!
