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.
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
pipes.
■ 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
components 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.
■ Ensure the electrical cables
are properly connected to the
terminals, otherwise there is a
risk of fire.

Important points
prior to installation
It is essential that you verify
the correct assignment
of electrical cables and
refrigerant pipes!
Do no mix up the connections
between circuits.
Such a mistake could be fatal!
CAUTION
Use letters to mark the
refrigerant pipes
(injection and suction pipes)
and associated electrical
control cables on each indoor
unit. Ensure the pipes and
cables are joined to the
corresponding connections.
NOTE
Different refrigerant pipes
may be required for the RM
326 depending on the cooling
output of the indoor unit.
