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").
■ 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.
