Installation instructions for qualified personnel

Important points prior to
installation
Locate the unit in original
■
packaging as close as possible
to the installation point to avoid
transport damage.
Check the contents of the
■
packaging for completeness
and check the unit for visible
transport damage. Report
any damage immediately to
your contracting party and the
shipping company.
Lift the unit at the corners
■
and not on the refrigerant or
condensation connections
The refrigerant pipes
■
(injection and suction pipe),
valves and connections must be
insulated impervious to vapour
diffusion. If necessary, insulate
the condensation pipe also
Select an installation location
■
which allows air to freely
flow through the inlet and
outlet. (See section "Minimum
clearances").
16
Do not install the unit in
■
the immediate vicinity of
devices with intensive thermal
radiation. Installation near
sources of thermal radiation
reduces the unit output.
Open the blocking valves of the
■
refrigerant pipes only after the
installation is complete.
Seal off open refrigerant pipes
■
with suitable caps or adhesive
strips to avoid infiltration of
moisture and never kink or
compress the refrigerant pipes.
Avoid unnecessary bends
■
. This minimises the pressure
loss in the refrigerant pipes and
ensures that the compressor
oil can flow back without
obstruction.
Make special preparations
■
regarding the oil return if the
outdoor unit is located above
the indoor unit. (See section
"Oil return flow measures").
Add refrigerant if the basic
■
length of the refrigerant pipe
exceeds 5 metres.

For the quantity of additional
refrigerant, refer to chapter
"Add refrigerant".
Only use the union nuts for
■
the refrigerant pipes provided
in the delivery scope, and
remove them just shortly before
connecting them with the
refrigerant pipes.
Make all electrical connections
■
according to valid DIN and DE
regulations.
See electrical connection

diagram. Always attach
electrical cables properly in
electrical clamps. Otherwise a
fire could result.
