➤ Stick the 2.5 m insulating tape (10 x 20 mm) to the cab roof, following the
outline of the sunroof opening (fig. 5, page 5).
➤ Provide the abutting edge and the top edge of the insulating tape with an
unhardened plastic butyl sealing compound (e.g. SikaLastomer-710).

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.
➤ Place the spacer sleeve L = 18 mm (fig. 6 1, page 5) on the fastening drill
holes as shown in fig. 6, page 5.
➤ Screw one hex screw M8 x 40 mm (fig. 6 4, page 5) with a washer
(fig. 6 2, page 5) and spring washer (fig. 6 3, page 5) in the 8 thread
inserts on the bottom of the unit.
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.
➤ Tighten the screws with a torque of 8 Nm.
