inspectionofevaporator
1. Check the radiating ribs of evaporator to see whether there is
block.
If the radiating rib is blocked, clean it with the compressed air.
Notice: do not wash the evaporator with water.
2. Check the joint to see whether there is crack or scrape.
Make reparation as requirement.
Mount the evaporator parts:
(a) Connect the expansion valve to the entrance joint of evaporator
and screw up the nuts.
Remark: Carefulness should be put on the O-ring seal.
(b) Mount the bracket on the suction pipe with thermal sensor;
(c) Connect the liquid pipe to the entrance joint of expansion
valve and screw up nuts.
(d) Mount the lower cluster housing on evaporator.
(e) Mount the upper cluster housing;
(f) Mount the four screws;
(g) Mount the two clipes;
(h) Mount the HP/LP pressure rubber washer; and
(i) Connect the plugging elements;
1. Mount the refrigeration device.
Mount the refrigeration device with three nuts.
2. Connect the plugging elements;
3. Mount the right glove box (SY rear air-conditioner: mount the
interior trim panel at left rear side).
4. Mount the insulation ring on the inlet and outlet joints;
5. Connect the liquid pipe to the outlet joint of refrigeration device;
Tightening moment(see page AC-8)
6. Connect the suction pipe to the outlet joint of refrigeration pipe;
Tightening moment(see page AC-8)
7. Connect the cathode lead to the storage cell.
8. Vacuumize the air-conditioning system:
Vacuumizing time:
Dr SL SK SF SJvacuumize for 20min and maintain the
pressure for 30min
SY: vacuumize for 30min and maintain the pressure for
another 30min.
9. Inflate the refrigerant in the air-conditioning system and
check to see whether there is air leakage;

On-vehicle inspection
1. Check the pipelines of each part to see whether there is
leakage:
Make the inspection with the gas leakage detector and, if
necessary, change them.
2. Check the clamping parts of the pipelines to see whether
there is looseness;
Make a new fastening or change as requirement.
Change of refrigerant pipeline
1. Exhaust the refrigerant;
2. Change the damaged pipe or hose
Remark: the opened joint should be sealed right away with
cork so as to prevent the humid from entering into the system.
3. Screw up the O-ring seal joint and threaded joint according
to the Tightening moment;
4. Vacuumize the air-conditioning system:
Vacuumizing time:
Dr SL SK SF SJVacuumize for 20min and main-
tain the pressure for 30min;
SYVacuumize for 30min and maintain the pres-
sure for another 30min.
5. Inflate the refrigerant in the air-conditioning system and
check the system to see whether there is air leakage;
