| Clean condenser during normal
service of the car Dirty and clogged condenser results
in A/C tripping and less cooling. |
Do not use A/C with fresh mode open.
This will lead to mixing of outside air with cool air
inside thereby reducing cooling effect. |
| Maintain
proper refrigerant level. Less refrigerant results in
less cooling. Excessive refrigerant results in less
cooling. |
Do not operate with A/C on. This will result
in mixing of hot air with cool air. |
| Add at
least 20 CC of DENSO-6 oil to the compressor during
refrigerant charging. Adequate quality of compressor oil
prevents poor pumping and premature wearing of internal
components. |
Do not operate A/C without refrigerant in the
system. This will result in premature failure of
compressor. |
| Clean
evaporator properly to remove dust and foreign
particles. Clogged evaporator results in less air flow
and reduced cooling. |
Do not leak check the A/C system with more
than 20KG/CM2 pressure. Higher pressure may result in
damage to A/C components. |
| Adjust
fresh air and heater cable properly to close damper’s
firmly. Unadjusted cable will result in mixing of hot
air with cool air. |
Do not leave A/C joints open. Moisture tends
to enter the A/C system if the joints remain for a long
time. |
| Refer to
the owner’s manual on proper usage of A/C controls.
Proper usage of A/C control will give optimum
cooling. |
Do not charge refrigerant in the A/C system
without carrying out proper vacuum. Improper or no
vacuuming of the A/C system results in less cooling
conditions. |
| Adjust
proper engine RPM. Less rpm will result in stalling of
engine and less cooling. |
|
| Check
coolant level and ensure proper engine tuning. This will
prevent overheating of the engine. |
|
| Check
position of accelerator cut off switch in 1000cc cars.
Improper position of accelerator cut off switch will
result in tripping. |
|
| Check
proper belt tension. Loose belt will slip and over tight
belt will result in noise and premature failure of
magnetic clutch of the compressor. |
