Volkswagen Polo Service & Repair Manual: Receiver/Dryer
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. |
|
|
|
| The receiver/dryer collects the fluid drops and then directs
them in an uninterrupted stream to the expansion valve. Moisture
which has entered the refrigerant circuit during repairs will be
collected by the dryer bag in the receiver/dryer. |
 Note
| Replace the receiver/dryer if refrigerant circuit has been
open for a long time (beyond the normal repair time) and
moisture has penetrated inside, or if required due to a specific
complaint. Refer to
→ Chapter „Components, Replacing“. |
| Only remove sealing plugs shortly before installation. |
| A dryer bag in an unsealed receiver/dryer is saturated with
moisture after a short period of time and unusable. |
| When installing, note arrow for direction of flow if
necessary. |
|
|
|
| The new generation of receivers/dryers are installed
directly on the condenser and contain a dryer cartridge. |
Note
| Replace the dryer cartridge if refrigerant circuit has been
open for a long time (beyond the normal repair time) and
moisture has penetrated inside, or if required due to a specific
complaint. Refer to
→ Chapter „Components, Replacing“. |
| Remove dryer cartridge from packaging shortly before
installation. |
| The dryer cartridge becomes saturated with moisture and
unusable after a short time in an unsealed package. |
