Assembling the Indoor Unit
Mounting plate:
The mounting plate for the indoor unit must be
positioned horizontally
Minimum clearances must be observed. Please
use the screws provided.
Wall opening:
One opening in the wall with a minimum
diameter of 70 mm is necessary for the passage
of the condensation pipe and the refrigerant and
electrical leads from the indoor unit to the outdoor
unit (for adapted refrigerant connection pipes for
the indoor unit or for KSS split pipes) A smaller
opening, approx. diam. 55 mm, may be sufficient
for non-adapted devices [without refrigerant
couplings]. A sleeve should be placed in the wall
opening in order to prevent damage to the pipes
(in particular to the insulation of the split pipes)! It
is better to pass the refrigerant connection pipes
of the indoor unit through the wall than the split
pipes themselves as some of these have a larger
diameter and are thus difficult to lay in a small
space (at the rear of the indoor unit).
1 Insulated suction pipe
2 Pressure pipe
3 Control line
4 Condensation pipe
5 Electric connecting cables (not in diagram)
Important: The opening must slope downward at
an angle of about 5° so that the condensation
formed during de-humidification and cooling can
run away. (The end of the condensation pipe may
not be standing in water or be below the water
line!)
Position for wall opening
The diagram below shows the recommended
position for the wall opening in relation to the
mounting plate if the pipes are not to be visible in
the room after installation.
and attached firmly.
In combination with KMSL split pipes only the
position shown on the right, where dimensions are
given, is suitable for the rear!
If you use your own split leads you may be able to use
the position shown on the left (of the mounting plate) in
relation to the wall opening.
Hanging slots
KSS 2504A / 3204A
KSS 4504C / 6004C
Please note that the bends in the refrigerant
pipes may not be positioned immediately in front of
or after the refrigerant couplings or the screw
fastenings for the leads!
If it does not matter whether the pipes are visible
in the room, they can all be led out of the side of
the indoor unit to the left (in the direction of the
pipe connections of the indoor unit; the perforated
areas in the casing of the indoor unit should be
cut out for this) and led through the wall in some
other suitable place.
Indoor unit:
Slot the indoor unit into the mounting plate and
close the clips provided in the lower part of the
casing.
Sealing the wall opening:
This is not done until the outdoor unit has been
installed and all necessary connections between
the indoor and the outdoor unit have been made.
The wall opening, or the remaining openings in
the wall opening sleeve, can be sealed using the
sealant provided, using mortar or a mineral fibre
plug with a silicone coating. In the case of fire
protection walls, the provisions of DIN 4102 must
be observed.
