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.
■
The indoor units and
chillers work independently.
A connecting line between
the two is not necessary.
■
Transport the unit in its original
packaging as close as possible
to the installation location.
You avoid transport damages
by doing so.
■
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.
■
Select an installation location
which allows air to flow freely
through the inlet and outlet.
(See section "Minimum
clearances").
■
Do not install the unit in the
immediate vicinity of devices
which generate intensive
thermal radiation.
Installation near thermal
radiation reduces the unit
output.
■
Lift the unit at the corners
and not by the medium or
condensate connections.
■
The medium connection lines,
valves and connections must be
insulated against vapour density
insulation. If necessary, also
insulate the condensate line.
In dual systems with
cooling and heating modes,
the requirements of the current
Energy Savings Ordinance
(German EnEV rule ) are to be
complied with.
■
Seal off open lines against
dirt and never kink or crimp
the lines.
■
Avoid unnecessary bends.
This minimises the pressure loss
in the lines.
■
Make all electrical connections
in accordance with applicable
DIN and VDE standards.
■
Always attach electrical lines
properly in electrical clamps
(otherwise a fire could result).
Installation materials
The indoor unit is attached to
the wall by a wall bracket and
4 screws (to be provided by
the customer).
Selection of 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
repair work and for
optimum air distribution.
