A/C System3A-17

Maintenance Warning and
Instruction

Treatment of the refrigerant

1. Please avoid inhaling the air containing the

refrigerant or lubricant vapor, for these gases
may cause irritation to eyes, nose and throat.
For environmental concerns, we strongly
recommend that the recovery/recycling/filling
equipment be adopted for R134a emission
from the A/C system. If an accidental leak in
the system may occur, please ensure the work
area is well ventilated before continuing the
maintenance.

2. Do not use the compressed air method to

perform the pressure or leak test for the
R134a maintenance equipment and/or the
vehicle A/C system. The mixture of R134a
and air at certain proportion is flammable
when the pressure is increased; if ignited, it
shall cause personal injury or property
damage. For other health and safety
information, please obtain from the
refrigerant supplier.

3. Do not let the refrigerant leak near an open

flame or other sources of heat. The refrigerant
will produce toxic gases when it is exposed to
the heat sources such as cigarettes or heaters.
If the operation may cause leakage, be sure to
avoid the above-mentioned heat sources and
maintain good ventilation.

4. Handling refrigerant is dangerous. Dripping a

drop of refrigerant on the skin will cause
localized frostbite; therefore, be sure to wear
gloves and goggles. If the refrigerant is
splashed into eyes, rinse with water
immediately and then go to the doctor.

Storage of the refrigerant

There is high pressure inside the refrigerant
reservoir. It may explode when being exposed to
the heat source, making metal fragments and
refrigerant splashing in all directions, which would
cause personal injury. The refrigerant should be
stored in the places with the temperature below 40
℃

{1040F).

Treatment of the compressor oil

1. Only the PAG 105# compressor oil can be

adopted for this vehicle and other kinds of oil
may cause damage to the A/C compressor.

2. Don’t let the PAG 105# compressor oil drop

on the vehicle body, or else the paint may
come off. If it drops on the vehicle body

accidentally, wiper it off immediately.

3. The PAG 105 # compressor oil is of higher

moisture absorption capacity than the
previously used mineral oil. The moisture
mixed into the compressor oil may cause
damage to the refrigeration system; therefore,
after the refrigeration system components are
removed, you should close the lid
immediately to prevent any moisture from
entering.

Maintenance Procedures for
Refrigeration System

Installing the manifold gauge

1. Close the valve on the SST(49C061001)

completely.

2. Connect the SST(49C061002, 49C061003)

and the SST(49C061001) respectively with
the low pressure port and the high pressure
port.

3. Connect the ends of the SST(49C061006A,

49C061007) and the SST(49C061002,
49C061003).

4. Connect the SST(49C061006A, 49C061007)

Warning:

1. Please avoid inhaling the air containing the

Connect the R134Ra
recovery/recycling/filling equipment with the
vehicle and operate it as per the
manufacturer’s instruction book.

Refrigerant filling

Warning:

Please avoid inhaling the air containing the
refrigerant or lubricant vapor, for these gases may
cause irritation to eyes, nose and throat. For
environmental concerns, we strongly recommend
that the recovery/recycling/filling equipment be
adopted for R134a emission from the A/C system.
If an accidental leak in the system may occur,
please ensure the work area is well ventilated
before continuing the maintenance.

Caution:

Please fill the system with proper amount of
refrigerant, for the excessive refrigerant will
reduce the operating efficiency of the A/C and
damage the refrigeration cycle system.

Recovering the used R134a refrigerant

Connect the R134Ra

recovery/recycling/filling equipment with the
vehicle and operate it as per the manufacturer’s
instruction book.

Adding fresh R134a refrigerant

1. Install the SST(manifold gauge) (Refer to

Installing the Manifold Gauge).

2. Connect the pin plug of the SST(49C061004)

with the bleeder valve of the
SST(49C061001).

3. Connect the SST(49C061005) with the central

port of the SST(49C061001).

4. Connect the SST(49C061005) with the

vacuum pump.

5. Connect the SST(49C061004) with the

refrigerant reservoir.

6. Put the refrigerant reservoir on the scale.

Specified refrigerant capacity:

600g{21. 20z)

675g{23. 80z): in extremely hot areas

7. Open all the valves of the ST(49C061001).

Caution:

Close the SST valves immediately after turning off
the vacuum pump; otherwise, the oil in the vacuum
pump will return to the refrigeration cycle system,
resulting in the decreased efficiency of the A/C
system.

8. Operate the vacuum pump for 15min.

9. Confirm the reading of the high and low

pressure ends of the SST(49C061001) is －
101kPa{ － 760mmHg, － 29.9inHg). Close
each valve of the SST(49C061001).

10. Turn off the vacuum pump and wait for 5min.

11. Check the reading of the high and low

pressure ends of the SST(49C061001). If the
value changes, check for any leak and start
from the step 7. If there is no change, go to
the step 12.

12. Open the valves of the refrigerant reservoir.

13. Weigh the reservoir.

Warning:

1) If the refrigeration system is filled with

excessive refrigerant or when there is any
leakage, the refrigerant would dissipate into
the atmosphere. In order to prevent the
damage to the ozone layer caused by the
accidental leakage, please perform the
correct steps for checking the leakage and
only add proper amount of refrigerant.

2) It is dangerous to operate the engine when

filling the system with refrigerant with the
high pressure valve of the reservoir open.
The pressure in the reservoir would increase
resulting in explosion, making metal
fragments and refrigerant splashing in all
directions, which would cause personal
injury; therefore, don’t open the high
pressure valve when the engine is operating.

14. Open the high pressure valve of the

SST(49C061001).

15. When the reading of the low pressure end

increases to 0.098MPa{1.0kgf/ cm2,14psi},
close the high pressure valve of the
SST(49c061001).

16. Use the SST(refrigerant leak detector) to

check the cooling pipe/hose for any leak. If
there is no leak, go to the step 17; if there is
leak due to the insecurely connected
connector, tighten the connector and recheck
for any leak. If the leak still exists, drain off
the refrigerant and repair the connector. Refill
the refrigerant from the step 7. If there is no

leak after the connector is tightened, go to the
step 17.

Warning:

It is dangerous to operate the engine when filling
the system with refrigerant with the high pressure
valve of the reservoir open. The pressure in the
reservoir would increase resulting in explosion,
making metal fragments and refrigerant splashing
in all directions, which would cause personal
injury; therefore, don’t open the high pressure
valve when the engine is operating.

17. Open the high pressure valve of the

SST(49C061001) and start to fill until the
weight of the reservoir is reduced by 300g110.
60zl compared to the weight obtained in the
step 13.

18. Close the high pressure valve of the

SST(49C061001).

Warning:

It is dangerous to operate the engine when filling
the system with refrigerant with the high
pressure valve of the reservoir open. The
pressure in the reservoir would increase resulting
in explosion, making metal fragments and
refrigerant splashing in all directions, which
would cause personal injury; therefore, don’t
open the high pressure valve when the engine is
operating.

19. Start the engine and turn on the A/C

compressor.

20. Open the low pressure valve of the

SST(49C061001) and start to fill until the
weight of the reservoir is reduced to the
specified amount compared to the weight
obtained in the step 13.

21. Close the low pressure valve of the

SST(49C061001) and the valve of the
refrigerant reservoir.

22. Turn off the engine and the A/C compressor.

23. Use the SST(air leak detector) to check for

any leak. If there is no leak, go to the step 24;
if there is leak due to the insecurely connected
connector, tighten the connector and recheck
for any leak. If the leak still exists, drain off
the refrigerant and repair the connector. Refill
the refrigerant from the step 7. If there is no
leak after the connector is tightened, go to the
step 24.

24. Separate the SST(49C061006A, 49C061007)

from the filler port.

25. Close the filler port cover tightly.

Adding the refrigerant

Warning:

Caution:

Please fill the system with proper amount of
refrigerant, for the excessive refrigerant will
reduce the operating efficiency of the A/C and
damage the refrigeration cycle system.
