"Denso's latest technology is used for manufacturing AC systems at Subros. Our strong infrastructure and focus on quality helps in making the best air conditioning systems in India."

Mr. D M Reddy
Chief Executive Officer



	Clean Condensor during normal service of the car.
	Dirty & Clogged Condensor results in A/C tripping and less cooling
	Maintain proper refrigerant level.
	Less refrigerant results in less cooling. Excessive refrigerant results in tripping and less cooling.
	Add atleast 20cc of DENSO-6 oil to the compressor during refrigerant changing.
	Adequate quantity of compressor oil prevents poor pumping and premature wearing of internal components.
	Clean evaporator periodically to remove dust and foreign particles.
	Clogged evaporator results in less air flow and reduced cooling.
	Adjust fresh air and heater cable properly to close damper's firmly.
	Unadjusted cable will result in mixing of hot air and cool air.
	Educate customer on proper usage of A/C controls (refer owners manual).
	Proper usage of A/C control will give optimum cooling.
	Adjust proper engine RPM.
	Less RPM will result in stalling of engine and less cooling.
	Check coolant level and ensure proper engine tuning.
	This prevent overheating of engine.
	Check position of accelerator or cut off switch in 1000cc and 1300cc 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.




	Do not open A/C with fresh mode open.
	This will lead to mixing of outside air with cool air inside thereby reducing cooling effect.
	Do not operate A/C with heater on.
	This will result in mixing of the hot air with cool air.
	Do not operate A/C without refrigerant in the system.
	This will result in premature failure of compressor.
	Do not leak check the A/C system with more than 20KG/CM2 pressure.
	Higher pressure may result in damage to A/C components.
	Do not leave A/C joint open.
	Moisture tends to enter the A/C system if the joints remain open for a long time.
	Do not charge refrigerant in the A/C system without carrying out proper vacuum.
	Improper or no vacuuming of the A/C systems results in less cooling conditions.
