NOTE

When only charging refrigerant without replacing any

component, replenish the same amount of measured

oil when recovering refrigerant, if not measured,

replenish 30cc oil.

PRESSURE TEST USINGMANIFOLDGAUGES

This is a method where trouble is detected and

repaired by using manifold gauge. The manifold

gauge indicates the refrigeration cycle high and low

pressure side pressures on the respective gauge.

NOTE

Make sure following conditions are fulfilled before

getting the correct gauge readings (after engine has

warmed –up

)

Engine speed

1500 rpm

A/C inlet temperature

(Ambient Temperature)

30° - 35° C (86° - 95°

Blower speed

High

Temperature Control

Full cold

Reference value be-

fore AC operation at

both high and low

pressure sides

5-8 kg/ cm

(0.5 - 0.8

MPa)
