Different cut-out sizes

The installation is possible for different cut-out sizes:
a) Install instead of a 400x400 mm roof hatch:
Dismount the roof hatch and use the remaining cut-
out. Remove sealant residue and unevenness. Fill in
screw holes with flexible non-hardening butyl body
sealant.
The adapter frame for 400x400 mm cut-outs is part of
the scope of delivery.
b) Install instead of a 360x360 mm roof hatch:
Dismount the roof hatch and use the remaining cut-
out. You need to buy the optional adaptor frame for
such cut-outs. It can be used instead of the
400x400 mm adaptor frame.

Remove sealant residue and unevenness. Fill in screw
holes with flexible non-hardening butyl body sealant.
c) Create a new cut-out:
Since the adaptor frame for 400x400 mm cut-outs is
part of the standard scope of supply this size may be
used.
If a smaller cut-out is preferred it is possible to buy as
accessory the 360x360 mm adaptor frame and use
this one.
Consult the vehicle manufacturer for the most suitable
way and position to create a new cut-out.
Before the installation, consider the installation
position:
■ Make sure that intended location does not interfere
with existing structures and cables.
■ The air conditioner shall be installed as close as
possible to the centre of the roof.
■ The installation position of the outdoor unit shall
be consistent with the traveling direction (F) of the
vehicle.
■ Make sure that there is sufficient room on the in-
side of the vehicle to install air distributor.
■ Consider the installation position of the air distribu-
tor and ensure that outlets of the air distributor are
at least 400 mm away from cupboards, walls and
bulkheads that can redirect conditioned air back
to the return air intake. If an outlet is closer than
400 mm from an obstruction, then it should be
sealed closed. Failure to do this will result in a unit
that frequently cycles on and off.
■ The cut-out shall avoid roof cladding joints where
ever possible.
■ Chose an installation position between two longitu-
dinal supports or sections, if existing.
■ There shall be a free space of 150 mm minimum to
the sides of the unit and 200 mm minimum to the
front and the back. the This to ensure suitable air
flow and access for maintenance.
WARNING
When a hatch with safety ventilation func-
tion is replaced by the air conditioner it
must be ensured that the safety ventilation
is restored in another location.
NOTE
Angle of inclination of the air conditioner
shall not be greater than 5° (=8,8%) and
the rear of the air conditioner shall not be
higher than the front.
