Assembly Instructions for
Service Personnel
Important instructions prior to installation
Prior to actual assembly, the following items have to be
checked and complied with:
à
Ensure that the contents of the package are com-
plete and that the units have no visible damage re-
sulting from transport.
Any problems must be communicated directly to
your contract partner and the shipping company.
à
Place the unit in its original packaging as close as
possible to the location where it will be assembled to
prevent damage from transport.
à
Select a location to set up the unit where air can flow
freely in and out of the device, where the unit is not
in direct sunlight and is not close to other sources of
heat.
à
Air should be distributed optimally throughout all ar-
eas of the room to be cooled and no drafts should be
created.
à
Prior to installation, check that the electrical connec-
tion values and the data on the type plate are consis-
tent.
à
Make sure that all electrical connections meet the
DIN-VDE requirements.
à
Lift the cassette on the corners and not with the re-
frigerant or condensation connections.
à
Prior to unit assembly, the connection adaptors for
the adjacent room connection and the fresh air con-
nection must be attached.
à
Carefully plan where the condensation line will be
laid.
à
Make sure that, if laid horizontally, there is an ade-
quate incline.
At least
2 %.
à
The integrated pump can bridge a maximum height
difference of 250 mm on top of the unit.
But only if the condensation line flows immediately in
a vertical direction after leaving the unit and then
continues at an incline.
à
Remove the protective caps of the unit connections
just before connecting the refrigerant lines.
à
The power supply is only connected to the outdoor
part. The control lines to the indoor unit should be
placed together with the refrigerant lines.
Common installation mistakes
When performing the installation, make sure to observe
the following to ensure smooth operation:
à
Do not install the unit in the direct vicinity of objects
that emit intense heat (e.g. lights). Install it in the
middle of the room instead.
Wall lead-throughs
Wall lead-throughs are necessary to establish the con-
nection between the indoor unit and the outdoor part.
Please observe the following:
à
For the connection line to the outdoor part, a lead-
through of at least 70 mm in diameter must be cre-
ated.
à
The lead-through must be placed at an incline of at
least 2% from the inside to the outside.
à
Make sure that there are no supply lines located in
the vicinity of the wall lead-through.
à
The air intake and outlet openings may not be
blocked by furniture, curtains, etc.
à
Prevent unnecessary bends in the refrigeration lines
to minimise the pressure loss and ensure that the
compressor oil can recirculate properly.
à
If the outdoor part is mounted above the indoor unit,
take steps to recirculate the oil.
à
If this line is connected to the drainage line, an odour
seal must be installed the upper edge of which may
not extend beyond the lower edge of the indoor unit.
à
The refrigerant lines may not be bent or pressed.
à
Protect open refrigerant lines from moisture with
suitable caps or adhesive.
à
Make sure that all refrigerant lines including all con-
nectors and valves are adequately insulated against
heat.
à
Mount the outdoor part in such a way that the differ-
ence height to the indoor unit is not more than 10 m.
à
Make sure that the maximum length of 15 m for the
basic length of the refrigerant line is not exceeded.
à
Use a balance to position the unit precisely which will
prevent condensation from leaking out.
à
Equip the ventilation lines for adjacent room cooling
and/or the fresh air connection including the connec-
tor piece with diffusion-sealed heat insulation.
à
Make sure that the electrical connections have been
properly attached to the terminals.

à
We recommend cushioning the inside of the hole or
lining it to prevent the lines from being damaged.
Suitable materials are, for example, PVC pipes with
an inner diameter of 70 mm.
à
After assembly is complete, the wall lead-through
must be sealed with a suitable sealing compound.
Do not use any materials containing cement or lime!
