return back within 10 min, it indicates that
the system is normal and the refrigerant can
be charged into the system.

(6) Restart the vacuum pump, and turn on the

low-pressure

valve

of the

manifold

pressure gauge to continuously vacuumize
15 min. Then, turn off the low-pressure
valve to stop vacuumizing, and prepare for
charging the refrigerant.

7. Refrigerant Recycling Equipment Operation Guide
Recycle

the

refrigerant

from

the

refrigeration device
When the refrigerant is removed from the
refrigeration device under the following
conditions, a recycling receiver shall be
applied to recycle the refrigerant.
Before the components on the refrigerant pipe
are replaced.
When moisture or air enters into the
refrigerant pipe.
When excessive refrigerants are charged into
the system.

WARNING:

(1)

When the recycling receiver is required, take care to operate it according to the

requirements of device manufacturer's instructions.

(2) After the completion of recycling work, measure the level of compressor oil recycled so

that the same quantity of oils are added to the refrigeration device in the future.

Operation guide for refrigerant recycling receiver

1. Install the manifold pressure gauge kit on the service valve.

2. Recycle the refrigerant from the refrigeration device.

(a) Connect the intermediate hose to the recycling receiver.

(b) Operate the recycling receiver.

(c) Open the manual high- and low-pressure valves on the refrigeration pressure gauge kit.

1. After the completion of recycling work, turn off the recycling receiver.
2. Remove the manifold pressure gauge kit from the service valve.

The compressor is driven by engine crankshaft pulley via the M belt. When the shift lever
on the A/C control mechanism is shifted to the refrigeration position, the electromagnetic
clutch of A/C compressor engages, and the compressor pulley make the main shaft and
swash plate rotate and then pull the rocking plate to swing. The swinging of the rocking
plate pushes the piston to move, which creates the air pumping effect to compress the
low-temperature and low-pressure air-state coolant into the high-temperature and
high-pressure air-state coolant.

The motion parts of compressor are lubricated using the sputtered refrigerant oil and the oil
in coolant. During the operation of compressor, due to the rotation and swing of the swash
plate, the refrigerant oil will be sputtered to anywhere. In addition, due to the intersolubility
of coolant and oil, when the coolant flows into the compressor, it also carries a part of
refrigerant oil which is available to lubricate the motion parts inside the compressor.

ADJUSTMENT OF ELECTROMAGNETIC CLUTCH

1. Use a thickness gauge to measure the clearance between the platen and A/C compressor

pulley.

2. Check whether the clearance is in the range specified by the technical specification.

• If it is found that the result doesn’t conform to the requirement of technical specification,

remove the platen, and use one or several shims to adjust the clearance.

Clearance:

0.6mm±0.2mm

3. Removal/Inspection of condenser

(1). Drain off the coolant from the system (see the

coolant recycling procedure)

(2). Remove the front bumper and headlamp crossbeam

assy.

(3). Remove the fluid reservoir and the refrigeration

pipes connecting to the condenser.

Check the condenser:

(1) Check the crack, damage or oily fluid leakage.

·Replace the condenser if any failure above occurs.

(2) Check whether the fender position is blocked by dust
or not.

·Clean it if blocked.

(3) Check the bent condition of fender position.

·Use a flat headed screwdriver to straighten the fender
