Insufficient Refrigerant

1. Symptoms seen in refrigerating cycle

• Both 

LO

 and 

HI

 pressure side (1), (2) pressures too low.

LO

 pressure side (1)

0.05 to 0.10 MPa (0.5 to 1.0 kgf/cm

2

, 7.1 to 14.2 psi)

HI

 pressure side (2)

0.69 to 0.98 MPa (7 to 10 kgf/cm

2

, 99.6 to 142.2 psi)

• Bubbles seen in sight glass.

• Air discharged from air conditioner sightly cold.

2. Probable cause

• Gas leaking from some place in refrigerant cycle.

3. Solution

• Check for leakage with electric gas leak tester (see page

G-70) and repair.

• Recharge  refrigerant  to  the  proper  level.  (See  page

10-S21.)

Excessive Refrigerant or Insufficient Condenser Cooling

1. Symptoms seen in refrigerating cycle

• Both 

LO

 and 

HI

 pressure side (1), (2) pressures too high.

LO

 pressure side (1)

0.20 to 0.35 MPa (2.0 to 3.5 kgf/cm

2

, 28.4 to 49.8 psi)

HI

 pressure side (2)

1.96 to 2.45 MPa (20 to 25 kgf/cm

2

, 284.5 to 355.6 psi)

2. Probable cause

• Overcharging refrigerant into cycle.

• Condenser cooling faulty.

3. Solution

• Clean condenser. (See page G-30.)

• Adjust  air  conditioner  belt  to  proper  tension.  (See  page

G-29.)

• If  the  above  two  items  are  in  normal  condition,  check

refrigerant quantity. (See page 10-S21.)

NOTE

• If excessive refrigerant is to be discharged, loosen

manifold gauge LO pressure side valve and vent out
slowly.
