Faulty wiring
Faulty groundChecksActionCheck for short and replace fuse.
Check battery voltage.
Check connectors’ connection.
Do not apply grease. This can cause voltage down.

DIAGNOSIS USING THE MANIFOLD GAUGE
On normal operation during the cooling cycle, the
manifold gauge must indicate approximately 1.5 - 2.0
kg/cm
2 at low pressure side and 14.5 - 15 kg/cm2 at
high pressure side, on condition that the temperature
at the cooler inlet, 30 ºC - 35 ºC, 2,000 rpm of the
engine rpm , full cold and maximum blower speed.
Cause Symptom
Action
1. High and low pressure are abnormally low.
2. Air at cooler outlet is not cold.
1. High and low pressure are abnormally high.
1. High and low pressure are abnormally high.
2. Connection at the low pressure is not cold.
There is a gas leak in the
cooling system.
Insufficient cooling and
faulty condenser cooling
by excessive
refrigerant.
Belt is slipped
There is an air in the
cooling system
Check the oil leak,
repair
Add the refrigerant
Keep the specified
amount of the
refrigerant, Clean the
condenser
Repair the belt
Clean and repair the
receiver-drier
Check the oil
contamination etc.

Operation Check
Notice: Operation Check is recommended before
removing the manifold gauge.
1. Install the manifold gauge set.
2. Run the engine at 2,000 rpm and set the blower
switch at ‘HI’ and A/C switch ‘ON’. Set the
temperature control lever at ‘COOL’.
3. Keep opening all of the window and door.
4. Place a dry bulb thermometer to the front duct.
5. Place a psychrometer close to the inlet of the
cooling unit.
6. Check the high pressure gauge reading within
14 - 16 kg/cm
2
If the reading indicates high excessively, spray
the water to the condenser.
If the reading indicates low excessively, cover the
condenser with the towel.
7. Check the temperature of air inlet within 25 - 35 °C.
8. Calculate the relative humidity from the
psychrometic graph comparing the wet/dry
temperature at the air inlet.
9. Measure the wet/dry temperature at the cold air
outlet and calculate the temperature difference of
the dry bulb between the inlet and the outlet.
10. Check the cross point of the relative humidity and
check the temperature difference between the
black line. If the cross point is located between
the black line, the cooling performance is normal.
4. The discharging pressure increases when the
charging valve charges excessively, so charge
the charging valve to the specified amount with
measuring the weight of the refrigerant before
closing the high pressure valve.
5. Charge the specified amount of the refrigerant and
then close the valve of the manifold gauge. Check
the system for any leak.
