CHARGING M1552001200403
Use the refrigerant recovery station to charge the refrigerant.
METHOD BY USING REFRIGERANT RECOVERY
AND RECYCLING UNIT
Using the refrigerant recovery and recycling unit, refill the
refrigerant.
NOTE: Refer to the Refrigerant Recovery and Recycling Unit’s
Instruction Manual for operation of the unit.
DISCHARGING SYSTEM
Use the refrigerant recovery unit to discharge refrigerant gas
from the system.
NOTE: Refer to the Refrigerant Recovery and Recycling Unit’s
Instruction Manual for operation of the unit.
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 dis-
charge air temperature.
When a compressor is installed at the factory, it contains 140
ml 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 sys-
tem.
When the following system components are changed, it is nec-
essary to add oil to the system to replace the oil being removed
with the component.
Compressor oil: ND Oil 8
Quantity:
Evaporator: 40 ml
Condenser: 40 ml

PERFORMANCE TEST M1552001400526
The vehicles to be tested should be parked out of direct sun-
light.
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 charging hose (red) to the high-pressure
valve of the gauge manifold.
3. Install the quick joint (for low-pressure) to the charging hose
(blue), and connect the quick joint (for high-pressure) to the
charging hose (red).
To connect the quick joint, press section A firmly
against the service valve until a click is heard.
When connecting, run your hand along the hose while
pressing to ensure that there are no bends in the hose.
4. Connect the quick joint (for low-pressure) to the
low-pressure service valve and connect the quick joint (for
high-pressure) to the high-pressure service valve.
NOTE: The high-pressure service valve is on the A/C pipe
and the low-pressure service valve is on the suction hose.
5. Start the engine.
6. Set the A/C controls as follows:
A/C switch: A/C ON position
Mode selection: FACE position
Temperature control: MAXIMUM COOLING position
Air selection: RECIRCULATION position
Blower switch: Maximum air volume
7. Adjust engine speed to 1,500 r/min with A/C clutch engaged.
8. Engine should be warmed up with doors and windows
closed.
9. Insert a thermometer in the center air outlet and operate the
engine for 20 minutes.
NOTE: If the A/C clutch cycles, take the reading before the
clutch disengages.
10.Note the discharge air temperature.

LOST CHARGE
If the system has lost all of its refrigerant charge due to a leak:
1. Evacuate the system. (Refer to P.55-142).
2. Charge the system with approximately 0.453 kg (1 pound) of
refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
Replacement filter-dryer units must be sealed while in
storage. The dryer used in these units will saturate water
quickly upon exposure to the atmosphere. When installing
a dryer, have all tools and supplies ready for quick assem-
bly to avoid keeping the system open any longer than nec-
essary.
6. Replace receiver dryer. (Refer toP.55-168).
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 pres-
sure 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.
HANDLING TUBING AND FITTINGS
Kinks in the refrigerant tubing or sharp bends in the refrigerant
hose lines will greatly reduce the capacity of the entire system.
High pressures are produced in the system when it is operat-
ing. Extreme care must be exercised to make sure that all con-
nections 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 fit-
ting 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 pres-
sure 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.
