Installation instructions for qualified personnel
Important points prior to
installation
■ Transport the unit in its original
packaging as close as possible
to the installation location 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 by the refrigerant or
condensation connections.
■ The refrigerant pipes (injection
and suction pipe), valves and
connections must be insulated
impervious to 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.
■ 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 component 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.
The quantity of additional
refrigerant is given in chapter
"Add refrigerant".
■ Only use the union nuts for the
refrigerant pipes included in
the delivery, and remove them
shortly before connecting the
refrigerant pipes.
■ Establish all electrical
connections in accordance with
the relevant DIN- and VDE
standards.
■ See electrical connection
diagram always properly
insert electrical cables into the
electrical terminals. Otherwise a
fire could result.
