6. MAINTENANCE
6.1 Safety
Information
Observe the safety information and regulations in chapter 1.4.
6.2 General
a)
Only trained personnel in authorized repair depots may perform any work on the
coolant system.
b)
As with all parts of a vehicle, the air conditioner is also subjected to constant
stress. To ensure perfect operation of the system and to prevent damages to the
parts, the prescribed service work must be performed regularly.
c)
The correct handling of the system with records of all prescribed service work is
required for the any warranty claims for damages to parts subject to service.
6.3
Care and Maintenance
a)
Independent of the following time plan, shortly after the first use of the vehicle,
check all device mountings and coolant lines for tightness.
b)
Even when the air conditioner is not in operation, wear to or loosening of
individual components may occur from normal aging or from driving. Therefore,
the corresponding checks are to be performed independent of the system
operating time.
c)
Independent of the operating time for the system, there may be a loss of coolant
even if the line connections are perfectly sealed. Due to the material structure of
the coolant hose lines, these have a diffusion rate that can vary according to the
ambient temperatures. If there is a relatively large loss of coolant in a short
interval, then it can be assumed that there is a leak in the system.
d)
If the condenser or vaporizer blades are only slightly soiled, clean them by
applying compressed air against the normal air flow.
If these are highly soiled or greasy, first use soapy water or a suitable cleaning
solution (not aggressive to copper or aluminium) to clean them and then use
compressed air or water.
e)
The filter dryer must be changed at least once per year. When working on the
coolant system, change the accumulator dryer as a rule.
