DISCHARGING SYSTEM Use the refrigerant recovery unit to discharge refrigerant gas from the system. REFILLING OF OIL IN THE A/C SYSTEM Too little oil will provide inadequate compressor lubrication and cause a
compressor failure. Too much oil will increase discharge air temperature.
When a compressor is installed at the factory, it contains 140 cm
3 (4.7 fl.oz) of
refrigerant oil. While the A/C system is in operation, the oil is carried through the
entire system by the refrigerant. Some of this oil will be trapped and retained in
various parts of the system.
When the following system components are changed, it is necessary to add oil to
the system to replace the oil being removed with the component.
Compressor oil: SUN PAG 56

Quantity:

Evaporator: 60
cm
3 (2.0 fl.oz)

Condenser:
15 cm
3 (0.5 fl.oz)
Suction hose: 10 cm3 (0.3 fl.oz)

PERFORMANCE TEST The vehicles to be tested should be parked out of direct sunlight.
1. Close the high and low-pressure valve of the gauge manifold.
2. Connect the charging hose (blue) to the low-pressure valve and connect the

REFRIGERANT LEAK REPAIR PROCEDURE LOST CHARGE If the system has lost all charge due to a leak:
1. Evacuate the system. (Refer to
CHARGING
and
DISCHARGING
).
2. Charge the system with approximately 0.453 kg (1 pound) of refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
6. Replace receiver drier.
7. Evacuate and charge system.
LOW CHARGE If the system has not lost all of its refrigerant charge; locate and repair all leaks. If it
is necessary to increase the system pressure to find the leak (because of an
especially low charge) add refrigerant. If it is possible to repair the leak without
discharging the refrigerant system, use the procedure for correcting low refrigerant
level. COMPRESSOR NOISE CHECK You must first know the conditions when the noise occurs. These conditions are:
CAUTION: Replacement filter-drier units must be sealed
while in storage. The drier used in these units
will saturate water quickly upon exposure to the
atmosphere. When installing a drier, have all
tools and supplies ready for quick assembly to
avoid keeping the system open any longer than
necessary.

ADJUSTMENT 1. Select a quiet area for testing. Duplicate conditions as much as possible.
Switch the compressor on and off several times to clearly identify compressor
noise. To duplicate high ambient conditions (high head pressure), restrict air
flow through the condenser. Install a manifold gauge set to make sure
discharge pressure doesn't exceed 2,070 kPa (300.2 psi).
2. Tighten all compressor mounting bolts, clutch mounting bolt, and compressor
drive belt. Check to assure clutch coil is tight (no rotation or wobble).
3. Check refrigerant hoses for rubbing or interference that can cause unusual
noises.
4. Check refrigerant charge. (Refer to
CHARGING
and
DISCHARGING
).
5. Recheck compressor noise as in Step 1 .
6. If noise still exists, loosen compressor mounting bolts and retighten. Repeat
Step 1 .
7. If noise continues, replace compressor and repeat from Step 1 .
