Installation instructions for qualified personnel
■
Transport the unit in its original
packaging as close as possible
to the installation location.This
avoids transportation damage.
■
Check that the packaged
contents are complete and
inspect the unit for any visible
signs of transportation damage.
Immediately notify any
deficiencies to the contractual
partner and forwarding agent.
■
Lift the unit by its corners
and not the refrigerant or
condensation connections.
■
Insulate the refrigerant pipes
(injection and suction pipe),
valves and connections to make
them tight against vapour
diffusion.If necessary also
insulate the condensation pipe.
■
Select an installation location
which allows air to freely
flow through the inlet and
outlet.(see section "Minimum
clearances").
■
Do not install the unit
adjacent to any hotspots.Unit
performance will be impaired if
installed next to hotspots.
■
Only open the stop valves
for the refrigerant pipes after
installation has been fully
completed.
■
Use caps or adhesive tape to
seal off the open refrigerant
pipes and prevent the ingress of
humidity.
Never kink or push in the
refrigerant.
■
Avoid unnecessary bending.
This minimises the pressure
loss in the refrigerant pipes and
ensures that the compressor
oil can flow back without
obstruction.
■
Special measures concerning
the oil return pipe must be
taken if the outdoor component
is mounted above the indoor
unit.
(See section "Oil return
measures").
■
Add refrigerant if the basic
length of the refrigerant pipe
exceeds 5 metres.
The amount of additional
refrigerant is given in the
chapter "Adding refrigerant".
■
Only use the union nuts
supplied with the refrigerant
pipes. These should only
be removed shortly before
connecting the refrigerant
pipes.
■
Establish all electrical
connections in accordance with
the relevant DIN- and VDE
standards.
■
Connect the electrical cables
properly to the terminals.
Otherwise there is a risk of fire.
■
Service openings should be
provided in the suspended
ceiling to allow maintenance
access to the control box.
■
Any ventilation ducts or pipes
and connection fittings, which
are used to connect a second
room or supply fresh air, should
be insulated with
diffusion-tight
material.
Wall breakthroughs
■
The wall breakthrough must
have a diameter of min. 70 mm
and a fall of 10 mm from inside
to outside for each indoor unit.
■
We recommend that the
inside of the hole is padded or
lined, e.g. using a PVC tube,
to prevent the pipes being
damaged.
■
After installation has been
completed, use a suitable
sealing compound to close
off the wall breakthrough
(responsibility of customer).
Do not use cement- or lime-
based materials!
