5.  CHECKING AND CHARGING REFRIGERANT 

CYCLE

[1]  CHECKING WITH MANIFOLD GAUGE

IMPORTANT

• The gauge indications described in the following testing are those taken under the same condition, so it

should be noted that the gauge readings will differs somewhat with the ambient conditions.

Condition

• Ambient temperature: 30 to 35 °C (86 to 95 °F)

• Engine speed: Approx. 1500 min

-1

 (rpm)

• Temperature control lever: Maximum cooling position

• Air-Conditioner switch: 

ON

• Blower switch: 

HI

 position

Manifold Gauge Connecting and Test Preparation

1. Close the manifold gauge 

HI

 and 

LO

 pressure side valve (4), (5)

tightly.

2. Connect  the  charging  hose  (7)  (red)  to  the 

HI

  pressure  side

charging valve (2) and connect the charging hose (1) (blue) to

the 

LO

 pressure side charging valve (6).

NOTE

• Be sure to drive out the air in the charging hoses at the

manifold gauge connection end by using the refrigerant
pressure in the refrigerating cycle.

3. Start the engine and set at approx. 1500 min

-1

 (rpm).

4. Turn on the A/C switch and set the temperature control lever to

maximum cooling

 position.

5. Set the blower switch to 

HI

 position.

Normal Operating

If the refrigerating cycle is operating normally, the reading at the

LO

 pressure side (1) should be generally by around 0.15 to 0.2 MPa

(1.5 to 2.0 kgf/cm

2

, 21 to 28 psi) and that at the 

HI

 pressure side (2)

around 1.27 to 1.66 MPa (13 to 17 kgf/cm

2

, 185 to 242 psi).
