7.4 Electrical Connection

The following electrical connections must be established on the
heat pump:
Connection of the control wire to terminals X2: L/N/PE in the
control box of the heat pump.
Connection of the load wire to terminals X1: L1/L2/L3/PE in
the control box of the heat pump.
Connection of the brine pump (to be supplied by the cus-
tomer) to terminal PE and pump contactor K5: 2/4/6 on the
control panel of the HP.
All electrical components required for the operation of the heat
pump are located in the control box.
For more detailed instructions concerning the connection and
functioning of the heat pump controller (e.g. the supplied external
wall sensor) please refer to the enclosed operating manual of the
controller.
An automatic circuit-breaker with simultaneous tripping of all ex-
ternal conductors is to be provided in the load power supply. The
circuit-breaker must be an all-pole disconnect device with a con-
tact gap of at least 3 mm. The same applies to any additional dis-
able contactors that may be required, e.g. during shut-off periods
imposed by the utility company. The required cross-sectional
area of the conductors is to be selected according to the power
consumption of the heat pump, the technical connection require-
ments of the relevant utility company and all applicable regula-
tions. Power consumption data of the heat pump is provided in
the product literature and on the nameplate. The connection ter-
minals are designed for the appropriate currents.
ATTENTION!
The clockwise phase sequence must be observed when connecting the
load lines (the heat pump will deliver no output and will be very noisy
when the phase sequence is incorrect).
The power cable must be run through the guide tubes, inserted
into the side of the control box and secured by means of the
strain relief.

Start-Up

8.1 General

To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorised by the
manufacturer. This may be a condition for extending the guaran-
tee. (see warranty service)

8.2 Preparation

Prior to commissioning, the following items need to be checked:
All connections of the heat pump must have been made as
described in Chapter 7.
The heat source system and the heating circuit must have
been filled and checked.
The strainer must have been fitted in the sole inlet of the
heat pump.
In the brine and heating circuits all valves that might impair
the proper flow must be open.
The settings of the heat pump controller must be adapted to
the heating installation in accordance with the instructions
contained in the controller's operating manual.

8.3 Procedure

The start-up of the heat pump is effected via the heat pump con-
troller.
ATTENTION!
Commissioning is to be effected in accordance with the installation and
operating manual of the heat pump controller.
Any malfunctions occurring during operation are displayed on the
heat pump controller and can be corrected as described in the
operating manual of the heat pump controller.
