LA 60P-TUR
The relevant components in the heat pump contain an internal
overload protection.
When connecting, ensure that the incoming supply has a clock-
wise rotating field.
Phase sequence: L1, L2, L3.
CAUTION!
Ensure that there is a clockwise rotating field: With incorrect
wiring, starting of the heat pump is prevented. A
corresponding warning is indicated on the display of the heat
pump manager (adjust wiring).
 The control voltage is supplied via the heat pump manager
(controller -N1).
A 3-pole line must be laid for this in accordance with the
electrical documentation. Further information on the wir-
ing of the heat pump manager is available in the heat pump
manager operating instructions.
 A shielded communication line (J-Y(ST)Y ..LG) (not in-
cluded in the scope of supply) connects the heat pump
manager (controller -N1) with the controller -N0 installed in
the heat pump. More detailed instructions can be found in
the heat pump manager operating instructions and in the
electrical documentation (included with the switch box).
NOTE
The communication cable is necessary for the function of
air-to-water heat pumps in outdoor installation. It must be
shielded and laid separately from the mains cable.
7.5.3 Demand sensor connection
The demand sensor R2.2 (NTC 10) is included with the heat
pump manager (controller -N1). It must be installed depending
on the hydraulics used (see cap. 3 on page VII).
If a demand sensor is not connected, the second heat genera-
tor cannot be controlled with the heat pump manager in the
event of an interruption in communication either.
NOTE
The return sensor R2 installed in the heat pump is active when
the compressor is running and must not be disconnected.

Commissioning

8.1 General

Commissioning must be carried out by trained personnel. Spe-
cialist tools must be used. To ensure that commissioning is per-
formed correctly, it should only be carried out by an after-sales
service technician authorised by the manufacturer (Fig. 1.1 on
page 2). Under certain conditions, this may be associated with
an additional warranty service.
CAUTION!
Commissioning, maintenance and repair only by personnel
who have verifiably been trained in dealing with the
refrigerant propane.

8.2 Preparation

The following items must be checked prior to commissioning:
The casing covers of the heat pump must be mounted on

all sides.
 There must be no ignition sources in the safety zone.
Personal protective equipment (protective goggles, safety

shoes and gloves where necessary) must be used when
working on the device.
All of the heat pump connections must be installed as de-

scribed in chapter 7.
 The heating circuit must have been filled and checked.
The leakage tightness of the refrigerant circuit must be

tested after all assembly work is complete and the external
power supply (load and control voltage) has been con-
nected. The leakage tightness test is described in the
maintenance instructions.
All valves which could impair the proper flow in the heating

circuit must be open.
 The air intake and air outlet paths must be clear.
The fan must turn in the direction indicated by the arrow.

The settings of the heat pump manager (controller

-N1) must be adapted to the heating system in accordance
with the operating instructions.
 Ensure that the condensate drain functions properly.
