Fig. 7.2:
The hydraulic 4-way reversing valve (6) preassembled with the
actuator is fixed on a transport plate (7) inside the unit with its th-
readed flanges (see Fig. 7.2 on page 7). After dismantling the hy-
draulic 4-way reversing valve from the device compartment, the
transport plate (7) must be removed. The threaded flanges of the
4-way reversing valve must be loosened. The connections ele-
ments and the flange gaskets are placed, together with the pro-
tective filter in the accessory box (8), on the plate heat ex-
changer. Two preassembled pipe assemblies (9) are placed on
the baseplate of the heat pump. These pipe assemblies must be
connected with the threaded flanges as shown in Fig. 7.3 on
page 7.

Fig. 7.3:
The clearances shown in Fig. 7.3 on page 7 must be achieved
with the sealing process between the double nipple and threaded
flange on the heat pump on the one hand, and between 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. 7.4 on page 8 to Fig. 7.7 on page 8. 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).
