Assembly

7.1 General

The following connections need to be established on the heat
pump:
 Flow and return of the brine (heat source system)
 Assembly of the hydraulic 4-way reversing valve Y12
 with the double nipples (2
the heat pump can also be used as external thread seal-
ing
 Flow/return heating to the hydraulic 4-way reversing valve
 Power supply
 Temperature sensor

Fig. 7.1:
The hydraulic 4-way reversing valve (1) preassembled with the
actuator is secured on the baseplate with 3 mounting brackets.
The mounting brackets must be removed and the flange gasket
placed under the 4-way reversing valve must be used (see
Fig. 7.1 on page 6.). Additional flange gaskets are located to-
gether with the threaded flanges in the accessories kit (2). The
connections elements are placed, together with the protective
filter in the accessory box (3), on the plate heat exchanger. A
preassembled pipe assembly (4) is placed on the baseplate and
an additional pipe assembly (5) is secured in the upper section
on the sheet metal part. These pipe assemblies must be con-
nected with the threaded flanges as shown in Fig. 7.2 on
page 6.

7.2.2 Assembly
Fig. 7.2:
The clearances shown in Fig. 7.2 on page 6 must be achieved
with the sealing process between the double nipple and
threaded flange on the heat pump on the one hand, and be-
tween the "heating water flow" pipe assembly and threaded
flange on the other. When the required installation position is
achieved, the flanges with the accompanying seals must be
connected with the hydraulic 4-way reversing valve using
screws, washers and spring washers.
The hydraulic 4-way reversing valve can be mounted in the four
positions shown Fig. 7.3 on page 7 to Fig. 7.6 on page 7. The
correct position of the motor control lever is pointed out again
in detail according to its installation position and depending on
the operating mode (heating or cooling).
