Receiver Dryer: Service and Repair

Removing and installing the fluid tank

Removal
1. Remove the cover above the heating/air-conditioning system and fluid tank.
2. Remove refrigerant by suction using the service unit.






3. Undo the hose clamp on the fluid tank. Undo both hexagon-head bolts on the fluid tank and remove the fluid tank upwards. Immediately close lines with plugs so that they are air-tight.

Installation
1. Do not remove the plug until shortly before installation. Replace the O-ring on the branch piece and on the refrigerant line, and wet the new O-rings with refrigerant oil.
2. Tighten both hexagon-head bolts on fluid tank with 6 Nm (4.4 ft lb).
3. Determine the quantity of the refrigerant oil and fill up again with refrigerant oil (volume removed by suction + 30 cubic cm).

NOTE: The fluid tank must be replaced if the system suffers from operational faults (e.g. accident damage or air-conditioning system depressurized).

Refrigerant oil removed from a previously run air-conditioning system may no longer be used (special category waste).
