DO’s AND DON’T’s
SR.
NO.
DO’s
REASON
1.
Clean condenser During Regular Service
of the Vehicle
Dirty and Clogged Condenser Results in AC tripping
and less cooling
2.
Maintain proper Refrigerant level
Less Refrigerant Results in less cooling. Excessive
Refrigerant Results in AC tripping and less cooling
3.
Add Recommended oil and Quantity in the
compressor during refrigerant charging.
Adequate Quantity of Compressor oil prevents poor
pumping and premature wearing of internal
components.
4.
Clean evaporator periodically to remove
dust and foreign particles.
Clogged evaporator results in less air flow and
reduced cooling.
5.
Educate Customer on proper usage of AC
controls (Refer owner’s manual)
Proper usage of AC control will give optimum cooling
6.
Adjust proper engine rpm.
Less rpm will result in stalling of engine and less
cooling.
7.
Check coolant level and ensure proper
engine tuning
This will prevent overheating of engine.
8.
Check proper belt tension. (For details
refer Engine group).
Loose belt will slip and over tight belt will result in
noise and premature failure of magnetic clutch of the
compressor.
SR.
NO.
DON’TS
REASON
1.
Do not operate AC without refrigerant in
the system of compressor.
This will result in premature failure
2.
Do not leak check the AC system with
more than 20 kg / cm2 pressure.
Higher pressure may result in damage To AC
components.
3.
Do not Leave AC joints open.
Moisture tends to enter the AC system if the joints
remain open for long time.
4.
Do not charge refrigerant in the AC system
without carrying out proper vacuum.
Improper or No vacuuming of the AC system results in
less cooling conditions.
