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
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
Lift the unit on the corners and not on the
refrigerant or condensate drainage connec-
tions.
n
The refrigerant piping (liquid and suction pipe),
valves and connections must be insulated to
make them vapour diffusion proof. If necessary
also insulate the condensate drainage line.
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
Install the refrigerant piping from the indoor unit
to the outdoor unit.
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.
n
Only use the union nuts supplied with the
refrigerant piping and remove these shortly
before connecting the refrigerant piping.
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 for maintenance
access.
Installation materials
The indoor unit is suspended from the corners of
the units by means of hangers. Wall plugs, trape-
zoidal sheet metal supports, steel profiles, fixing
clamps for refrigerant and condensate drainage
lines (as well as laying ducts) and connection fit-
tings for condensate drainage lines must be pro-
vided by the customer.
Selecting the installation location
The indoor unit is specifically designed for hori-
zontal mounting in suspended ceilings with Euro-
raster dimensions. However, it can also be
installed in suspended ceilings with different
dimensions. Take into account the installation
height of the equipment.
Minimum clearances
Observe the minimum clearances to allow access
for maintenance and repair work and facilitate
optimum air distribution.
