|
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 overtight belt will result in
noise and premature failure of magnetic clutch of the
compressor. |
