Installation Notes for Split Air Conditioners
Before choosing a room air conditioner, we recommend carrying out a cooling load calculation according to
the standard, or on the basis of a relevant standard. Forms for cooling load calculation complete with
instructions can be obtained from the manufacturer or wholesaler or in the Internet at www.dimplex.de.
Note: Indoor or outdoor units which are not installed according to instructions may cause a reduction or loss
of warranty in the case of repair.
Choosing the installation location
It is very important to install split devices in suitable locations, as it is difficult, and thus expensive, to move
them after installation. If possible, decide on the installation location in agreement with the final customer.
The installation must be suitable for bearing the weight and the operational vibration of the indoor or outdoor
unit on a permanent basis.
Notes on the installation of the indoor unit
- The circulating air should flow through the whole of the room to be cooled.
- The flow of cold air should not be directed at persons or their place of work.
- The condensation formed during cooling must be drained off without impairing functioning. If
condensation can only be led off upwards or without a downward slope, then the installation of a
condensation pump is necessary.
- The unit may not be installed in rooms subject to high humidity in which the device is in contact with
moisture or water.
- The device may not be installed in rooms in which oil vapour is emitted or could be emitted.
Notes on the installation of the outdoor unit
- The outdoor unit should be installed in a place where it will not become soiled.
- When there is a danger of condensation freezing (heating operation when outside temperatures are low),
the condensate drain stubs should be removed and additional insulation be provided for the drainage
area. Freezing condensation (e.g. the formation of ice on the heat exchanger) can impede the fan
function of the outdoor unit.
- The outdoor unit must be installed in compliance with the regulations regarding the assessment of
operational noise in the neighbourhood. In particular, a suitable distance from bedrooms and similar
rooms should be maintained.
- The device may not be installed in areas of aggressive air!
Scope of supply
Please check that the delivery is complete and that the devices are undamaged.
The scope of supply includes:
1. Split air conditioner consisting of an indoor and an outdoor unit (two VPE - for a complete order)
2. Mounting plate for wall mounting of the indoor unit, slotted into it (incl. screws)
3. Remote control (incl. 2 batteries)
4. Condensation drain plug for draining condensation in the outdoor unit
5. Assembly and operating instructions
6. Length of insulating tube (approx. 250 mm x diam. i20 mm)
7. Control line with connection plug and a connection cable to the power supply (see Technical Data)
8. Sealant (in box – for sealing the wall around the pipes)

8
Assembling the Indoor Unit
Mounting plate:
The mounting plate for the indoor unit must be
positioned horizontally and attached firmly.
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.
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.
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.

Minimum Clearances
Indoor unit
The following minimum clearances (A and B) from walls are essential for the trouble-free operation of the
room air conditioner and for servicing and repairs.
The clearance between the ceiling and the lower edge of the room air conditioner must be at least 2.30 m.
For device dimensions see Technical Data.
For all devices: A ≧100 mm B ≧180 mm

Assembling the Outdoor Unit
The outdoor unit should be attached firmly to a
suitable surface or a suitable wall of sufficient
strength (see also “Wall bracket accessory”).
It should be installed in a place where there is
unimpeded air inflow and outflow An air short
circuit must be avoided. Please observe minimum
clearances and the sound power levels given in
the technical data (distances from bedrooms or
third-party rooms etc.).
Condensation drainage in the outdoor unit
When the heat pump is in operation, condensation
is formed in the outdoor unit, which must be
drained off in a manner appropriate to the
location.
There is a hole (diam. 25) for condensation
drainage in the base plate of the outdoor unit into
which the condensation drainage plug supplied is
inserted. If the installation location allows it, the
condensation formed can simply drip away,
otherwise it must be led off through a pipe
attached to the drainage plug.
Caution:
During heating operation at temperatures below
+4 °C the condensation outlet can freeze up
under unfavourable conditions and this can block
the condensation fan. If temperatures below +4 °C
are to be expected at the condensation outlet
during heating operation, appropriate measures,
e.g. insulation (insulation of the base of the casing
and the condensation drainage area) should be
taken, or, if possible, the drainage plug should not
be installed. If a condensation pipe is used, it
must always slope downwards.

Connecting the cooling system for
devices with pre-filled refrigerant
pipes KMSL… .
The refrigerant pipes of the indoor and outdoor
units are pre-filled with refrigerant R407C or
R410A.
Please observe the safety regulations for
handling CFC (HCFC) in the section “Pre-filled
refrigerant pipes KMSL…” when installing the
air conditioners and the split pipes.
(see page 12f.)
Split pipes of the KMSL series
Care must be taken to connect the refrigerant
pipes correctly. It is particularly important to
observe the torques specified (see page 14).
Incorrect connection of the split pipes, which can
be ordered as accessories, is impossible,
because each half of the coupling fits only to its
other half in the indoor or outdoor unit.
Ready-to-use refrigerant pipes in various lengths
are available (see Essential Accessories in
“Technical Data”). Excessively long pipes should
be avoided when selecting split pipes (loss of
cooling capacity). Reductions or extensions to
length may be made by the authorised after-sales
service only.
Please observe the assembly steps and the
notes in the section “Pre-filled refrigerant
pipes KMSL” on page 12ff. for installation and
the connection of the cooling system.
