Volkswagen Golf Service & Repair Manual: Reservoir
| The reservoir collects the vaporised and gaseous mixture
coming from the evaporator to ensure the air conditioner
compressor receives only gaseous refrigerant. Gaseous
refrigerant is formed from the vapour. |
| Refrigerant oil flowing in the circuit does not remain in
the reservoir, as an oil extraction hole has been provided. |
| Moisture which has entered the refrigerant circuit during
repairs will be collected by a filter (dessicant bag) in the
reservoir. |
| Gaseous refrigerant with oil is drawn in by the air
conditioner compressor. |
 Note
| Renew the reservoir if the refrigerant circuit has stood
open for any length of time (more than the normal repair time)
and moisture has entered the system, or if it is required
because of a specific complaint
→ Chapter. |
| Do not remove sealing plugs -A-
and -B- until just before
installation. |
| The dessicant bag in an unsealed reservoir will become
saturated with moisture within a short time and is then
unusable. |
| When installing, observe arrow indicating direction of flow,
if applicable. |
