Installation instructions for qualified personnel
Important notes prior to
installation
devices with intensive thermal
radiation. Installation near
sources of thermal radiation
reduces the output of the unit.
■
Only open the shut-off valves
of the refrigerant lines after
the installation is complete.
■
Before connecting the injection
line, remove the valve core
in the indoor unit connection
ports.
■
Seal off open refrigerant lines
with suitable caps or adhesive
strips to avoid infiltration of
moisture and never kink or
compress the refrigerant lines.
■
Avoid unnecessary bends.
In doing so, you minimise loss
of pressure in the refrigerant
lines and ensure clear return
flow of the compressor oil.
■
Take special precautions with
regard to the oil return if the
exterior component is located
above the indoor unit. (See
section "Oil return flow
measures").
■
If the basic length of the
refrigerant line exceeds
5 metres, add refrigerant.
The quantity of additional
refrigerant is provided in
the chapter "Add refrigerant".
■
Only use the union nuts for the
refrigerant pipes included in the
delivery, and remove them only
shortly before connecting the
refrigerant lines.
■
Make electrical connections
in accordance with the effective
DIN and VDE standards.
■
Always fasten electric cables
properly to the electrical
terminals. Otherwise a fire
could result.
The assembly and installation
of the units and components
may only be carried out by
especially trained technicians.
NOTE
■
Transport the unit in its original
packaging as close as possible
to the installation location.
You avoid transport damages
by doing so.
■
Check the contents of the
packaging for completeness
and check the unit for visible
transport damage. Report any
damage immediately to your
contractual partner and the
shipping company.
■
Lift the unit at the corners
and not by the refrigerant or
condensation connections.
■
The refrigerant pipes
(injection and suction line),
valves and connections must
be insulated 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 in
the immediate vicinity of
