Installation

5.1 General Information

The device should always be installed on a permanently smooth,
even and horizontal surface. To counteract development of any
solid-borne sound, the entire frame (and its supporting surface)
should be in contact with the floor. If this is not possible, addi-
tional constructional measures to improve sound insulation may
need to be provided by the customer. It must be possible to carry
out maintenance work without hindrance. This can be ensured by
maintaining a clearance of 1.2 m around the device.
ATTENTION!
Do not restrict or block the area around the air intake or outlet.

5.2 Condensed Water Pipe

Condensed water that forms during operation must be drained
off frost-free. The heat pump must be mounted on a level plane
to guarantee proper drainage. The condensed water pipe must
have a minimum diameter of 50 mm and must be fed frost-free
into a sewer or a suitably dimensioned, deep gravel drainage pit.
The condensate pipe should be centrically placed under the
drain stubs of the condensate tray (see also the dimension draw-
ing in the Appendix). Alternative means of condensate drainage
are to be agreed upon with the manufacturer.
Condensate should not be drained directly into clearing tanks
and cesspits because any rising, aggressive vapours could de-
stroy the evaporator.

6.1 General Information
The following connections need to be established on the swim-
ming pool heat pump:
Flow and return flow of the swimming pool system
Condensate outflow
Control line to remote control
Power supply

6.2 Swimming Pool Connections

The water pipe connections on the heat pump have 1" and/or
1 1/2" external threads. A pipe wrench must be used to firmly grip
the transitions when connecting the heat pump.
The water pipes are connected via a bypass on the filter circuit of
the swimming pool located downstream of the filter and upstream
of the water preparation system.
Before the water pipes are connected to the heat pump, the
swimming pool water system must be flushed to remove any im-
purities, sealant residue, etc. We strongly recommend installing
a filter system in the water circuit. Any accumulation of deposits
(leaves, grass or other organic contaminants) in the liquifier may
cause total breakdown of the heat pump. Suitable hydraulic in-
stallation, adjustment and dimensioning of the filter/circulating
pump ensures the minimum water flow rate through the heat
pump for trouble-free operation.
Once the water pipes have been installed, the system must be
filled, de-aerated and pressure-tested.
Minimum water flow rate
The swimming pool heat pump does not have an integrated cir-
culation pump. The required water flow rate must be provided by
an external filter pump and signalled back to the heat pump via
the respective input.
Antifreeze (frost protection)
Manual drainage (see "Hydraulic Plumbing Diagram" in the Ap-
pendix) should be provided for heat pumps exposed to frost. To
ensure frost protection, a method of allowing the heat pump to
activate the filter pump must be installed (see the information in
Chapter 9.4 on winter shutdown/lay-up measures).
