5 Installation Instructions
for qualified personnel
Important notes prior to installation
Observe the operating manuals for the indoor unit
and the outdoor unit when installing the entire
system.
n Observe the operating manuals for the indoor
unit and the chiller or heating system when
installing the entire system.
n The indoor units and chillers work independ-
ently. A connecting line between the two is not
necessary.
n Transport the unit in its original packaging as
close as possible to the installation location.
You avoid transport damage by doing so.
n Check the contents of the packaging for com-
pleteness and check the unit for visible trans-
port damage. Report any damage immediately
to your contractual partner and the shipping
company.
n Select an installation location which allows air
to freely flow through the air inlet and outlet
(see section "Minimum clearances").
n Do not install the unit in the immediate vicinity
of devices which generate intensive thermal
radiation. Installation in the vicinity of thermal
radiation reduces the unit output.
n Lift the unit at the corners and not by the
medium or condensate drainage connections.
n The medium connection lines, valves and con-
nections must have vapour density insulation.
If necessary, also insulate the condensate
drainage line. In dual systems with cooling and
heating modes, the requirements of the current
Energy Savings Ordinance (EnEV) are to be
complied with.
n Seal off open refrigerant piping with suitable
caps or adhesive strips to prevent the infiltra-
tion of moisture and never kink or compress
the refrigerant piping.
Avoid unnecessary bends. This minimises the
n
pressure loss in the lines.
n Install all electrical wiring in accordance with
applicable DIN and VDE standards.
n Ensure the electrical cables are properly con-
nected to the terminals. Otherwise there is a
risk of fire.
n Service openings should be provided in the
suspended ceiling to allow maintenance
access to the control box or the valve
assembly.
Installation materials
The unit is attached to the wall bracket by 4 screws
to be provided by the customer.
Selecting the installation location
The indoor unit is designed for horizontal wall
installation above doors. However, it can also be
used in the upper wall area (min. 1.75 m above the
floor).
Minimum clearances
Observe the minimum clearances to allow access
for maintenance and repair work and facilitate
optimum air distribution.
