Volkswagen Polo Service & Repair Manual: Pressure Relief Valve
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 pressure relief valve is installed on the A/C compressor
or receiver/dryer. |
| At a pressure of approximately 38 bar (551 psi) positive
pressure, valve opens and closes again once pressure has
dissipated (approximately 30 bar (435 psi)). |
| Refrigerant does not escape completely. |
| Depending on the version, a transparent plastic disc may be
installed which breaks off as soon as the valve is activated. |
