(1) When the refrigerant volume is proper:
Gauge reading:
Low pressure side:
0.28 ± 0.4 MPa (2.8 ± 4.0 kgf/cm
2)
High pressure side:
1.3 ± 1.6 MPa (13 ± 16 kgf/cm
2)
(2) When there is moisture in the refrigeration system:
SymptomProbable causeDiagnosisRemedy
During operation, pressure on low
pressure side cycles between nor-
mal and vacuum
Moisture in refrigeration system
freezes at refrigerant filter orifice,
causing a temporary stop of cycle.
However, when it melts, normal
state is restored
Drier is overly saturated

Moisture in refrigeration system
freezes at refrigerant filter orifice
and blocks circulation of refriger-
ant(1) Replace cooler drier
(2) Remove moisture in cycle by
repeatedly vacuuming
(3) Supply proper amount of new
refrigerant

(5) When the refrigerant does not circulate:
SymptomProbable causeDiagnosisCorrective Actions

Vacuum is indicated on low pres-
sure side, and extreamly low pres-
sure is indicated on high pressure
side

Frost or dew is seen on piping on
both sides of condenser or refrig-
erant filter

Refrigerant flow is obstructed by
moisture or dirt in refrigeration sys-
tem

Refrigerant filter is clogged
Refrigerant does not circulate
(1) Check the refrigerant filter
(2) Clean out dirt on refrigerant fil-
ter by blowing air
(3) Replace condenser
(4) Vacuum air and supply proper
amount of new refrigerant
(5) If refrigerant filter is damaged,
replace it
(6) When the refrigerant is overcharged or cooling of
condenser is insufficient:
SymptomProbable causeDiagnosisRemedy

Pressure is extreamly high on
both low and high pressure sides
Excessive refrigerant

Cooling performance of con-
denser is insufficient
Excessive refrigerant

Cooling performance of con-
denser is insufficient

Magnet valve assy is defective
(1) Clean condenser fins
(2) Check condenser fan motor
operation
(3) If (1) and (2) are in normal
state, vacuum and supply proper
amount of refrigerant
(4) If pressure is still high even af-
ter supplying refrigerant, replace
the magnet valve assy

tions occur when the refrigera-
tion system opens and the re-
