Push the motor on the sleeve.
Make sure not to rotate the sleeve during this action, so as to
maintain the valve position as set during step
4
.
7
Put the turn knob on the valve motor cover as shown below.
Make sure that the turn knob is completely pushed in to allow
the turn knob being operated automatically by the unit. If the
turn knob is lifted slightly, manual operation is possible.

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.
6
Connect the flexible hoses as indicated in
figure 4
,
figure 5
,
figure 6
and
figure 7
.
■
The 2 flexible hoses with quick coupling connections on both
sides must be connected to the foreseen coil connection (for
EKHBRD units see
figure 4
, for EKHVH/X units see
figure 5
,
for EKHVMRD units see
figure 6
, for EKHVMYD units see
figure 7
).
■
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 as
indicated in
figure 4
,
figure 5
,
figure 6
,
figure 7
). 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 hoses.
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 (for EKHBRD units see
figure 4
, for
EKHVH/X units see
figure 5
, for EKHVMRD units see
figure 6
, for EKHVMYD units see
figure 7
).
