Installation instructions
for qualified personnel
Important notes prior to installation
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.
n
Avoid unnecessary bends. This minimises the
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
Only install the valve assembly or other attach-
ments once the indoor unit has been installed.
Installation materials
The indoor unit is attached using 4 bolts to be pro-
vided by the customer.
Selecting the installation location
Wall / ceiling unit
The indoor unit is designed for vertical wall installa-
tion, for instance underneath windows. However, it
can also be used in the upper wall area (max. 1.25
m above floor level).
The unit is also designed for horizontal ceiling
installation. In this case particular attention must
be paid to the condensate drainage (see the
Chapter "Condensate drainage connection").
Connection variants
The following connection variants can be used for
the medium and condensate pipes and the control
lines.
