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. C a l c u l a t e t h e r e l a t i v e h u m i d i t y f r o m t h e
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.

COMPRESSOR OIL
REPLACEMENT
Before Oil Replacement
When any part is replaced or there are a lot of gas
leaks in the A/C system, you should add the specified
amount of the oil to keep the approval oil capacity
because the oil for lubricating the compressor
circulates through the A/C system during operating
the compressor.
Handling Oil
•
Be careful that moistures, dusts etc. must not flow
into the oil.
•
Do not mix with any other material.
•
If the oil leaves outside for long time, it’s possible
to mix it with the moistures and so keep the oil
sealed with a container.
Circulating Oil
For checking or adjusting the oil level, set the control
unit to full cold and max blower speed with keeping
the engine run at idle for 20 - 30 minutes in order to
circulate the oil through the compressor.
