Caution
| Non-approved tools or materials such as leak sealing
additives can cause damage or malfunctions in the
system. |
| Only use tools and materials approved by the
manufacturer. |
| The warranty is voided if non-approved tools or
materials are used. |
|
| All components of the refrigerant circuit submitted for
quality observation are always to be sealed (use original
sealing caps of original part). |
| Replace damaged or leaking components of refrigerant
circuit. Refer to
→ Chapter „Components, Replacing“. |
| To date, the original parts (compressor, reservoir,
receiver/dryer, evaporator and condenser) have been filled with
nitrogen gas. This charge is being gradually discontinued. There
is little or no pressure equalization when removing the sealing
plugs from the original part. |
|
|
|
| These o-rings seal off the connection points between
individual components of the refrigerant circuit. |
| Only O-rings that are resistant to refrigerant r134a and
refrigerant oil must be installed. Make sure they are original
replacement parts. |
| Refer to the Parts Catalog. |
| Make sure diameters -a- and
-b- are correct. |
| Coat with refrigerant oil before installing |
 Note
| The color coding of refrigerant circuit o-rings with R134a
