Volkswagen Polo Service & Repair Manual: Reservoir
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 reservoir collects the vaporized and gaseous mixture
coming from the evaporator to ensure the compressor only
receives gaseous refrigerant. Gaseous refrigerant is formed from
the vapor. |
| The refrigerant oil flowing in the circuit is not retained
in the reservoir as it has an oil drilling. |
| Moisture which has entered the refrigerant circuit during
repairs will be collected by a filter (desiccant bag) in the
reservoir. |
| Gaseous refrigerant is extracted with oil by the A/C
compressor. |
 Note
| Replace the reservoir 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 sealing plugs -A- and
-B- only immediately prior to
installing. |
| A desiccant bag in an unsealed reservoir is saturated with
moisture after a short period of time and unusable. |
| When installing, note arrow for direction of flow if
necessary. |
