Volkswagen Polo Service & Repair Manual: A/C without Magnetic Clutch with Torsion-Elastic Clutch
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 A/C compressor is driven directly by the power steering
vane pump. |
| On the A/C compressor driveshaft, there is an overload
protection that shears off when the compressor is blocked so
that the power steering vane pump remains functional. |
| The A/C compressor extracts the refrigerant gas from the
evaporator, compresses it and relays it to the condenser. |
 Note
| The A/C compressor contains refrigerant oil, which can be
mixed with refrigerant R134a under any temperature. |
| The type plate lists the type of refrigerant required for
the A/C compressor. A regulator valve regulates pressure within
the specified range (control characteristics) on the low
pressure side. |
| On this A/C compressor, the control valve is activated from
outside. |
| The engine should only be started if the refrigerant circuit
is completely assembled. Refer to
→ Chapter „Refrigerant Circuit, General Precautions“. |
| The A/C compressor is equipped with a protected oil supply,
this prevents A/C compressor damage in the event that the system
is empty. This means that approximately 40 to 50 cm3
of refrigerant oil remains in the A/C compressor. |
