ing roof unit. You can use fig. 1, page 3 and fig. 2, page 3 to check
the dimensions of the installed unit. The dotted line indicates the mid-
dle of the sunroof opening.
Before installation, find out (by consulting the manufacturer of the
vehicle) whether the construction is designed for the static weight and
the loads of the parking cooler when the vehicle is in motion. The
manufacturer of the air conditioning roof unit assumes no liability
whatsoever.
The roof inclination of the mounting surface may not exceed 8° in the
direction of travel.
The supplied assembly parts must not be modified during installation.
The ventilation slots (grill) may not be covered (minimum distance
from other attachment parts: 10 cm).

7.2 Removing the sunroof
➤Remove all screws and fixtures of the existing sunroof.
➤Take out the sunroof.
➤Remove the sealant around the opening, so that the surface is clean
and free of grease.
I
7.3 Preparing the unit fastening
➤Enlarge the existing ∅6.5 mm drill holes for fastening the sunroof to
a diameter of 8.5 mm (fig. 55, page 5).
7.4 Preparing the unit
A
➤Place the air conditioning roof unit on a work surface with the housing
facing down.
A
➤Screw in the 8 self-threading M8 thread inserts in the blind holes
marked with “1” (fig. 31, page 4).
Use the supplied 1/4" bit for this.
NOTE
Dispose of all waste material, glue, silicone and seals separately.
Observe the local disposal guidelines.
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.
NOTICE!
Screw in the thread insert vertically.
Do not exceed the screw torque of 10 Nm.

CoolAir RT780 Installation
7.5 Attaching the seal for the cab roof
A
➤Stick the 2.5 m insulating tape (10 x 20 mm) to the cab roof, following
the outline of the sunroof opening (fig. 4, page 4).
➤Provide the abutting edge and the top edge of the insulating tape with
an unhardened plastic butyl sealing compound (e.g.
SikaLastomer-710).
7.6 Installing the unit in the sunroof
➤Set the unit down centrally aligned and in the direction of travel
(fig. 1, page 3) on the sunroof opening.
I
➤Place the spacer sleeve L = 18 mm (fig. 51, page 5) on the
fastening drill holes as shown in fig. 5, page 5.
➤Screw one hex screw M8 x 40 mm (fig. 54, page 5) with a washer
(fig. 52, page 5) and spring washer (fig. 53, page 5) in the
8 thread inserts on the bottom of the unit.
A
➤Tighten the screws with a torque of 8 Nm.
NOTICE!
Ensure that the adhesive surface for the seal between the unit and the
cab roof is clean (free of dust, oil, etc.).
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.
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.

7.7 Installing the electrical supply lines
!
A
I
You can connect the unit to the battery via the lorry's terminal block or
directly. The terminal block is to be preferred for the connection. Ask your
vehicle manufacturer for the specifications of the terminal block.
➤Lay the supply line and connect it to the vehicle (red line to plus, black
line to minus).
➤Plug in the supply line plug into the socket of the air conditioning roof
unit supply line.
➤To relieve strain on the supply line, secure it with a cable tie, e.g. to
the cab roof.
7.8 Fastening the cover frame
A
fig. 6, page 6
➤Fasten the cover frame (5) to the cab roof (original fastening points)
with the six self-tapping screws (7) and washers (6).
WARNING!
The electrical power supply may only be performed by qualified
personnel with specialist knowledge.
Make sure there is no voltage present on electrically operated
components before carrying out work on them!
NOTICE!
Fit a fuse of 25 amps to the connection to the vehicle's power supply.
The battery must be able to supply the required current and voltage
(chapter “Technical data” on page 24).
NOTE
The unit is equipped as standard with a 4 m long cable with a cross-
section of 6 mm2. If longer cable lengths are required, then the cable
cross-section must be increased by an authorised specialist workshop:
In this case cut off the cable as closely as possible to the unit
(max. 0.5 m) and then establish a suitable connection with a larger
cable cross-section.
When the cable is extended by 4 m to 6 m in length, the manufacturer
recommends using a cross-section of at least 8 mm2.
NOTICE!
Screw the screws in carefully order not to damage the cover frame.
