Installation instructions for qualified personnel
Important points prior to
installation
■ Observe the manuals for
the indoor unit and outdoor
component when installing the
entire system.
■ 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.
■ Seal off open refrigerant pipes
with suitable caps or adhesive
strips to avoid infiltration of
moisture and never kink or
compress the refrigerant pipes.
■ 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.
