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 / air­conditioning 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.
