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.

Installation

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
„
Control line to on-site release contact (floating)

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. When plastic pipes are con-
nected, suitable temperature measuring points should be pro-
vided directly on the flow and return flow connections of the
swimming pool heat pump (e.g. immersion sleeves).
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.
ATTENTION!
Never operate the heat pump without water flow!

Antifreeze (frost protection)
Manual drainage (see "Hydraulic Plumbing Diagram" in the Ap-
pendix) has to be provided for heat pumps exposed to frost. To
ensure frost protection, continuous operation of the filter pump at
air temperatures below 5°C must be ensured on site (e.g. by
using a frost protection thermostat) (see the information in
Chapter 9.4 "Winter Shutdown / Lay-Up").

6.3 Electrical Connection

Depending on device type, the heat pump is connected to the
power supply via a standard 3-core cable (1-phase devices) or
standard 5-core cable (3-phase devices).
The cable(s) is(are) to be provided by the customer. The con-
ductor cross section is selected in accordance with the power
consumption of the heat pump (see Appendix Device Informa-
tion) and the applicable VDE (EN) and VNB regulations.
Both an all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility blocking contactor or power contactor), as
well as a 3-pole and/or 1-pole circuit breaker with common trip-
ping for all external conductors (tripping current in compliance
with the Device Information) must be installed.
Ensure that the incoming supply has a clockwise rotating field
when connecting multiphase devices.
Phase sequence: L1, L2, L3.
ATTENTION!
Ensure that there is a clockwise rotating field (for multiphase devices):
Operating the compressor in the wrong rotational direction could cause
damage to the compressor. Incorrect phase sequence causes wrong
rotational direction of the ventilator and, thus, a significantly reduced
performance.
The device supplies the control voltage to the remote control.
The connecting cable (control line) from the remote control to the
heat pump (not included in the scope of supply) must be suitable
for a 230 V supply voltage. The cable must be 5-core (at least)
and have a single-core cross section of at least 0.5 mm².
The connection line from the heat pump to an on-site release
contact must be suitable for a network voltage of 230 V.
The heat pump does not have an integrated circulating pump.
The required water flow must be provided by an external filter
pump and signalled back to the heat pump via the respective in-
put. Terminals 2 and 3 of terminal strip X2 should be used for this
purpose. Release is made via a floating on-site contact (K29).
ATTENTION!
The flow monitor must be designed for the required volume flow and
ensure permanent interconnection.
The heat pump power supply is in accordance with the technical
data of the device: 1/N/PE ~ 230 V, 50 Hz or 3/N/PE ~ 400 V,
50 Hz.
The heat pump is connected via the terminal strips in the switch
box. For detailed information see Circuit Diagrams in the Appen-
dix.
