Compact Cooler 4E / 5 / 5 Lite / 8
CAUTION
If the heating option is installed (Compact
Cooler 8): Coolant level can only be
checked when the Webasto heating / air-
conditioning system Compact Cooler 8 is
switched off. I.e. the 2/3-position switch
must be in the neutral position.
1. The system must be installed in
accordance with the installation
instructions.
2. Installing the air-conditioning system
increases the height of the vehicle. Please
note the heights specified in the vehicle
papers and ensure registration if necessary.
3. If faults develop in the refrigerant circuit,
the system must be tested and repaired by
an authorised service centre. Under no
circumstances may refrigerant be vented
into the open air (see § 8 CFC-Halon
Prohibition Directive dated 06.05.1991).

4. Installation, maintenance, repair and all
work on the refrigerant circuit may only be
carried out by specialist personnel in an
authorised service centre. This work may
only be carried out with the engine at a
standstill and the power supply switched
off. The battery must be disconnected
before starting any work on the electrical
wiring.
5. Wear protective clothing and safety
goggles when handling refrigerant.
6. Regardless of how long the system is in
use, it is also possible to experience
refrigerant loss despite the line connections
being absolutely sealed. However, if
relatively large quantities of refrigerant are
lost over short periods of time, you may
assume that there is a leak in the system.
7. Only the materials, special tools and
accessories listed in the installation
instructions may be used for maintenance
work on the air-conditioning circuit.
8. As is the case with all parts of a vehicle,
the air-conditioning system is continuously
subjected to loading. To guarantee that the
system operates correctly and to prevent
any damage to the parts, the maintenance
work must be carried out at regular
intervals.
9. The proper treatment of the system and
a record of all maintenance work are
necessary for the acceptance of any
warranty claims involving damage to parts
that require regular maintenance.
10. Irrespective of the schedule in the
installation instructions, all the device
fasteners and the connections on the
refrigerant lines must be checked for firm
seating within the first four weeks of using
the roof-top system for the first time.
