9 Perform the wiring in the indoor unit switch box in accordance
with the following figure: (make sure power supply is
switched off)
Make sure to follow the appropriate wiring routing inside of
the unit (this wiring routing can be found in the installation
manual of the indoor unit).
Refer also to the wiring diagram delivered with the indoor
unit.
5 Mount the tank module on top of the indoor unit using the lifting
holes.
6 Connect the flexible hoses as indicated in figure 4 .
■
The 2 flexible hoses with quick coupling connections on both
sides must be connected to the foreseen coil connection (see
figure 4 ).
■
The 2 flexible hoses with quick coupling connection on one
side and threaded connection coupling on the other side
must be connected to the hot water outlet and cold water
inlet (they have to be routed out from the rear plate (see
figure 4 ). Depending on the installation location (left or right
side installation), punch the required right or left knockout
holes out of the rear plate. Apply the grommet to the edges of
the knocked out holes to protect the flexible piping.
If the recirculation connection is used, connect a tube with
threaded connection to this hole and guide it through a hole
in the rear plate too (see
figure 4 ).
7 Fix the side bottom decoration panels of the domestic hot water
tank to the indoor unit.
8 Connect the pressure relief valve (field supply, opening pressure
maximum 10 bar) and drain.
9 Connect the thermistor wire to the indoor unit switch box. Make
sure power supply is switched off. Refer to the wiring diagram
delivered with the indoor unit.
The distance between the thermistor cable and power supply
cable must always be at least 50 mm to prevent electromagnetic
interference on the thermistor cable.
1 Plug the thermistor cable connector in the socket X11A on
the PCB.
2 Fix the cables to the cable tie mountings with cable ties to
ensure strain relief.
