Installation instructions for qualified personnel
Important points prior to in-
stallation
■ 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 ship-
ping company.
■ Lift the unit at the corners and
not by the refrigerant or con-
densation connections.
■ The refrigerant pipes
(injection and suction pipe),
valves and connections must be
insulated impervious to vapour
diffusion. If necessary, also insu-
late the condensation pipe.
■ Select an installation location
which allows air to freely flow
through the inlet and outlet.
(See section "Minimum clear-
ances").
■ Do not install the unit in the
immediate vicinity of devices
with intensive thermal radia-
tion. 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 pres-
sure loss in the refrigerant pipes
and ensures that the compres-
sor oil can flow back without
obstruction.
