REFRIGERANT LEVEL CHECK,
DRAINING AND CHARGING

M1559200100334

Remove the refrigerant by the flon reclaim machine
and replenish the specified quantity of refrigerant.

NOTE: Refer to the Refrigerant Recovery and Recy-
cling Unit instruction Manual for operation of the unit.

REFILLING OF OIL IN THE A/C SYSTEM

M1552020000356

Too little oil will provide inadequate compressor lubri-
cation and cause a compressor failure. Too much oil
will increase discharge air temperature.

When a compressor is installed at the factory, it con-
tains 70 mL 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 or S10X
Quantity

Evaporator: 25 mL
Condenser: 15 mL
Each piping: 5 mL

TEST CONDITION SETTING

Check that the temperature/humidity of measure-
ment location satisfies the test conditions, and then
set the vehicle body conditions to the designated sta-
tus according to the test conditions. If the tempera-
ture/humidity is not within the test conditions, an
accurate judgment cannot be made. Therefore, post-
pone the performance test.

COOLING PERFORMANCE CHECK

ACB05874AB

Wet and dry bulb
thermometer

Thermometer

1. Insert a thermometer into the air outlet located at

the centre of instrument panel.

NOTE: Set a thermometer so that cool air from
the air outlet blows directly against the sensing
part.

2. Set a wet and dry bulb thermometer in the air

intake of the front passenger's foot area (below
the glove box).

NOTE: Set a wet and dry bulb thermometer so
that cool air does not blow against it.

3. Start the engine to warm up. Confirm that the

engine speed of the test condition is satisfied.

4. Set the A/C control panel to the mode instructed

in the test conditions.

5. Wait until the air outlet temperature is stable

(approximately 10 minutes after the A/C starts),
and measure dry-bulb/wet-bulb temperatures at
the air outlet and the air intake.

6. If the air outlet temperature is in the range

specified by the table below, it is judged normal. If
the temperature is outside the permissible range
in the table below, refer to the refrigerant gas
pressure inspection result, and check each
section according to the diagnosis chart of
refrigerant system.
