Installation instructions for qualified personnel
Important notes prior to
installation
■ 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
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.
■ 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.
You thereby minimize 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.
