Fitting
Fitting
Installation is carried out in the reverse order of removing, when doing this note the following.
Before fitting reservoir → Air conditioner with refrigerant R134a
–  Check type of seal at connections and refrigerant pipes (must be designed for same type of seal) → Chapter and → Spare parts catalogue
  Note
t  Connections at reservoir may be marked “IN” (from evaporator) and “Out” (to compressor).
t  The reservoir removed contains refrigerant oil which must be returned to the refrigerant circuit (together with the new reservoir) → Air conditioner with refrigerant R134a.
t  Adjustment of the oil quantity depends on the nature of the complaint. For example, when the reservoir is damaged as a result of an accident (refrigerant does not escape, dirt and moisture has not penetrated the refrigerant circuit), the air conditioner can be repaired without extensive work by weighing the old and new reservoirs. Fill the new reservoir with refrigerant until it has the same weight as the reservoir removed. → Air conditioning with refrigerant R134a
t  If an indeterminate quantity of refrigerant oil has escaped or dirt and moisture has penetrated the refrigerant circuit, clean the refrigerant circuit with compressed air and nitrogen. → Air conditioning with refrigerant R134a
   
–  Insert reservoir in holder -D-.
–  Engage holder -D- with lug -B-.
–  Insert bolts -A- and tighten to 8 Nm.
  A87-0410
–  Replace the O-rings -D-; for version refer to → Spare parts catalogue
–  Turn the reservoir such that the two refrigerant pipes -B- and -C- can be inserted without strain in the reservoir. In doing so, pay attention to correct assignment of connections.
–  Attach the refrigerant pipe with the bolt -A- to the reservoir (tightening torque 10 Nm for bolts with M6 thread and 25 Nm for bolts with M8 thread). Use strap wrench, for example, to prevent reservoir turning.
  A87-0409
–  Tighten bolt -C- (tightening torque 8 Nm).
  A87-0410
–  Check the distance from the refrigerant pipe -B- to the bolt -D- and to the holder. If necessary, fit a scuff guard -C- (e.g. a star-shaped piece of rubber as spacer → Spare parts catalogue).
  Note
If the reservoir -A- with part number “8E0 820 193” up to index “F” has been replaced by a reservoir with the same part number as of index “P” → Parts catalogue, a scuff guard -C- (e.g. a piece of star-shaped rubber as spacer → Spare parts catalogue) is always to be fitted.
–  Check the routing of the refrigerant pipes. They must not make contact with other components and the clearance must be sufficient to prevent scoring. Fit a scuff guard if necessary.
–  Re-install remaining components removed before.
–  Evacuate and refill the refrigerant circuit → Air conditioning with refrigerant R134a
