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 6-core (at least)
and have a single-core cross section of at least 0.5 mm².
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.

Start-Up

7.1 General Information

To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorized by the
manufacturer. Only then can an extended warranty period of 3
years in total be granted (see Warranty Service).
7.2 Start-Up
The following items need to be checked prior to start-up:
The heat pump must be fully connected, as described in
Chapter 6.
Any valves that might impair proper water flow in the water
circuit must be opened.
The air intake and air outlet paths must be clear.
The ventilator must turn in the direction indicated by the ar-
row.
The remote control must be operational.
Ensure the condensate outflow functions.
After connecting the operating voltage and switching on the
swimming pool heat pump, there will be a pre-programmed
5-minute compressor pause time before the heat pump
starts up.
The bypass and regulator valves must be set so that the
minimum water flow is in accordance with the Device Infor-
mation. The following maximum temperature spreads be-
tween water inlet and water outlet are set for the operating
point.
