Moisture Entered in the Cycle
1. Symptoms seen in refrigerating cycle
- The air conditioner operates normally at the beginning, but over
time, LO pressure side (1) pressure is vacuum and HI
pressure side (2) is low pressure.
LO pressure side (1) : Vacuum
HI pressure side (2) : 0.69 to 0.98 MPa
(7 to 10 kgf/cm
2
, 99.6 to 142.2 psi)
2. Probable cause
- The moisture in the refrigerating cycle freezes in the expansion
valve orifice and causes temporary blocking. After a time, the
ice melts and condition returns to normal.
3. Solution
- Replace receiver.
- Remove moisture in cycle by means of repeated evacuation.
(See page 10-S17.)
- Recharge new refrigerant to the proper level. (See page 10-
S21.)

Refrigerant Fails to Circulate
1. Symptoms seen in refrigerating cycle
- LO pressure side (1) pressure is vacuum and, HI pressure side
(2) is low pressure.
LO pressure side (1) : Vacuum
HI pressure side (2) : 0.49 to 0.59 MPa
(5 to 6 kgf/cm
2
, 71.2 to 85.3 psi)
- Frost or dew formed on piping at front and rear sides of
expansion valve or receiver.
2. Probable cause
- Refrigerant flow obstructed by moisture or dirt in the
refrigerating cycle freezing or sticking on the expansion valve
orifice.
3. Solution
Allow to stand for same time and then resume operation to
decide whether the plugging is due to moisture or dirt.
- If caused by moisture, correct by referring to instructions in
previous.
- If caused by dirt, remove the expansion valve and blow out the
dirt with compressed air.
- If unable to remove the dirt, replace the expansion valve.
Replace the receiver. Evacuate and charge in proper amount
of new refrigerant. (See page 10-S18 to S20.)
- If caused by gas leakage in heat sensitizing tube, replace the
expansion valve.
