Attaching the seal for the cab roof

A
NOTICE!
Ensure that the adhesive surface for the seal between the unit and the cab roof
is clean (free of dust, oil, etc.).
➤ Stick the insulating tape to the cab roof (fig. 8):
– 10 x 20 mm for the most common installation environments
– 35 x 20 mm (optional for RT780), if more space is required between the
unit and the cab roof
➤ Provide the abutting edge and the top edge of the insulating tape with an
unhardened plastic butyl sealing compound (e.g. SikaLastomer-710).
7.5

Preparing the unit (RT780 only)

A
NOTICE!
• During preparatory work on the surfaces, secure the unit from falling down.
• Make sure that the work surface is clean and level to ensure that the unit is
not damaged.
• Do not exceed the specified torque under any circumstances. This is the
only way to ensure that the thread inserts are not torn out.
Proceed as follows (fig. 9):
➤ Place the air conditioning roof unit on a work surface with the housing facing
down.
➤ Screw in the self-threading thread inserts in the corresponding blind holes.
7.6

Installing the unit in the sunroof

➤ Set the unit down centrally aligned and in the direction of travel (fig. 0) on
the sunroof opening.
I
NOTE
Make sure the air conditioning roof unit is centred perfectly. The seal must be
applied continuously around the air conditioning roof unit after being placed
on the roof of the vehicle. This is the only way to ensure a tight seal.
A
NOTICE!
Do not exceed the specified torque under any circumstances. This is the only
way to ensure that the thread inserts are not torn out.
