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.
