CHARGING M1552001200362
1. With the handles turned back all the way (valve
closed), install the adaptor valve to the
low-pressure side of the gauge manifold.
2. Connect the charging hose (blue) to the adaptor
valve.
3. Connect the quick joint (for low-pressure) to the
charging hose (blue).
CAUTION
•Use tools that are suited to R134a.
•To install the quick joint, press section 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.
NOTE: The low-pressure service valve should be
connected to the flexible suction hose.5. Close the high and low-pressure valves of the
gauge manifold.
CAUTION
Be sure to connect the power plug of the vacuum
pump to the vacuum pump adapter, and then
connect the power plug of the adapter to a 100-V
outlet.
6. Install the vacuum pump adaptor to the vacuum
pump.
7. Connect the charging hose (yellow) to the R-134a
connection port of the vacuum pump adaptor.
8. Tighten the adaptor valve handle (valve open).
9. Open the low-pressure valve of the gauge
manifold.
10.Turn the power switch of the vacuum pump to the
ON position.
NOTE: Even if the vacuum pump power switch is
turned ON, the vacuum pump will not operate
because of the power supply connection in step
(6).
CAUTION
Do not operate the compressor for evacuation.
11.Turn the vacuum pump adaptor switch to the
R134a side to start the vacuum pump.
12.Evacuate to a vacuum reading of 100 kPa or
higher (takes approx. 10 minutes).

25.After charging with refrigerant, turn the handle of
the adaptor valve back all the way (valve closed).
26.Tighten the charging valve handle (valve closed).
Remove the quick joint (for low-pressure) from the
low-pressure service valve.
27.Remove the service can.
NOTE: If the service can is not emptied
completely, keep the handles of the charging
valve and adaptor valve closed for the next
charging.

LEVEL IN CASE THE SERVICE CAN IN
USED
M1552014600100
1. Install the charge valve with the handle turned all
the way back (valve open) to the service can.
2. Install the adaptor valve with the handle turned all
the way back (valve close) to the charging valve.
3. Connect the charging hose (blue) to the adaptor
valve.
4. Connect the charging hose (blue) to the quick
joint (for low-pressure).
5. Tighten the handle of the charge valve (valve
close), and pierce the service can.
6. Turn the handle of the adaptor valve to bleed the
air.7. Install the quick joint (for low-pressure) to the
low-pressure service valve.
NOTE: The low-pressure service valve should be
connected to the suction hose.
8. Start the engine.
9. Operate the air conditioner and set at the lowest
temperature (MAX. COOL).
10.Fix the engine speed at 1,500 r/min.
11.Tighten the handle of the adaptor valve (valve
open), and replenish refrigerant while checking
the quantity through the sight glass.
12.After replenishing is completed, turn the handle of
the adaptor valve all the way back (valve close),
and remove the quick joint.
NOTE: When there is remainder of refrigerant in
the service can, keep it for next use with the
charge value and the valve of the adaptor valve
being closed.
DISCHARGING SYSTEMM1552013000105
Use the refrigerant recovery unit to discharge
refrigerant gas from the system.
NOTE: Refer to the Refrigerant Recovery and
Recycling Unit instruction Manual for operation of the
unit.
REFILLING OF OIL IN THE A/C SYSTEMM1552020000033
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 140mL <1300, 1600> or 120 mL <2000> of
compressor 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 mL
Condenser: 15 mL
Flexible suction hose: 10 mL
Receiver: 10 mL

PERFORMANCE TEST M1552001400355
1. The vehicles to be tested should be in a place that
is not in direct sunlight.
2. Close the high and low-pressure valve of the
gauge manifold.
3. 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.
CAUTION
•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. 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).NOTE: The high-pressure service valve is on the
A/C pipe and the low-pressure service valve is on
the suction hose.
5. 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.
6. Start the engine.
7. 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: "4" (Fast) position
8. Keep engine speed to idling speed with A/C clutch
engaged.
9. Engine should be warmed up with doors and all
windows opened.
10.Insert a thermometer in the centre air outlet and
operate the engine for 20 minutes.
NOTE: If the clutch cycles, take the reading before
the clutch disengages.
11.Note the discharge air temperature.
