2OAO464DISCHARGING SYSTEM
Since the air conditioning refrigerant system is pressurized, it
will be necessary to completely discharge the system (in a wellventilated area) before replacing any refrigerant component.
The procedure is as follows:
(1) Install manifold gauge set. Make sure the gauge set valves
are closed before attaching the hoses to the refrigerant
system.(2) Install a long hose to the manifold gauge set connector.
Run this hose to the oil collector can near a shop exhaust
system.A good oil collector can may be made from a large empty
coffee can with a plastic top. Slit the plastic top in the formof a
Y to make an entrance for the refrigerant hose and an
exit for the gas.
(3) Open the compressor discharge and suction line pressure
valves and blow the refrigerant into the oil collector can.
Watch to make sure the hose does not blow out of the
collector can.
(4) When the system has been completely discharged, mea-
sure the amount of oil collected in the can. The amount of
oil measured should be added to the refrigerant system
before it is re-charged. Add new oil-discard the used oil.
CautionIt is important to have the correct amount of oil in the
refrigerant system.
Too little oil will provide inadequate compressor lubrication
and cause a compressor failure. Too much oil will increasedischarge air temperature.
When a IOPAI 7 compressor is installed at the factory, it
contains 80 cc (4.8
cu.in.) of refrigerant oil. While the air
conditioning 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 partsof 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:30 cc (1.8 cu.in.1
Condenser:20 cc (1.2 cu.in.1
Evaporator:30 cc (1.8 cu.in.)

24-22 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures(9) Charge through the suction side of the system by slowly
opening the suction manifold valve. Adjust the valve as
necessary so charging pressure does not exceed 345
kPa 6(50 psi). Maintain the temperature of the water in the pan w’
by adding warm water as necessary.
Note the weight of water added, to ensure accuracy when

refrigerant hose lines will greatly reduce the capac-
ity of the entire system. High pressures are pro-
duced in the system when it is operating. Extreme
care must be exercised to make sure that all
connections are pressure tight. Dirt and moisture
can enter the system when it is opened for repair or
replacement of lines or components. The following
precautions must be observed.
The system must be completely discharged before
opening any fitting of connection in the refrigeration
system. Open fittings with caution even after the
system has been discharged. If any pressure is
noticed as a fitting is loosened, allow trapped
pressure to bleed off very slowly.Never attempt to rebend formed lines to fit. Use the
correct line for the installation you are servicing.
A good rule for the flexible hose lines is keep the
radius of all bends at least 10 times the diameter of
the hose.
Sharper bends will reduce the flow of refrigerant.
The flexible hose lines should be routed so that they
are at least 80 mm (3 in.) from the exhaust manifold.
It is good practice to inspect all flexible hose lines atleast once a year to make sure they are in good
condition and properly routed.

first know the conditions when the noise occurs.

24-24 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures
COMPRESSOR NOISENUFIABWhen investigating an air conditioning related noise, you must
first know the conditions when the noise occurs. These
conditions are: weather, vehicle speed, in gear or neutral,
engine temperature or any other special conditions.
Noises that develop during air conditioning operation can oftenbe misleading. For example: what sounds like a failed front
bearing or connecting rod, may be caused by loose bolts, nuts,mounting brackets, or a loose clutch assembly. Verify acces-
sory drive belt tension (power steering, or alternator).
Improper accessory drive belt tension can cause a misleading
noise when the compressor is engaged and little or no noise
when the compressor is disengaged.
Drive belts are speed sensitive. That is, at different engine
speeds, and depending upon belt tension, belts can develop
unusual noises that are often mistaken for mechanical prob-
lems within the compressor.
Adjustment Procedures
(1) Select a quiet area for testing. Duplicate conditions as
much as possible. Switch compressor on and off several
times to clearly identify compressor noise.
To duplicate high ambient conditions (high head pressure),restrict air flow through condenser. Install manifold gauge
set to make sure discharge pressure doesn’t exceed 2,070
kPa (300 psi).
(2) Tighten all compressor mounting bolts, clutch mounting
bolt, and compressor drive belt. Check to assure clutch coilis tight (no rotation or wobble).
(3) Check refrigerant hoses for rubbing or interference that cancause unusual noises.
(4) Check refrigerant charge (See “Charging the System”).
(5) Recheck compressor noise as in Step 1.
(6) If noise still exists, loosen compressor mounting bolts and
retorque. Repeat Step 1.
(7) If noise continues, replace compressor and repeat Step 1.
