Repair Section

(1) Connection of gauge manifold

1) Properly remove the crushed end of the pinch-off

tube at the high-pressure side and the low

pressure side of the refrigerant cycle with a pipe

cutter.

2) Fit the process tube fitting to the pinch-off tube on

both sides.

3) Connect the charging hoses (red high-pressure

side) for the gauge manifold to the process tube

fitting.

< NOTE >

Connect the hoses using care not to mistake

the high-pressure side for the low-pressure

side and vice versa.

4) Connect the charging hose (green) at the center

of the gauge manifold to the vacuum pump.

(2) Evacuation

1) Open the high-pressure valve (Hl) of the gauge

manifold.

2) Turn on the vacuum pump to start evacuation.

(Evacuate the system for approximately 15

minutes.)

3) When the high-pressure gauge indicates 30 inHg

(100 kPa) or higher, turn off the vacuum pump

and close the high-pressure valve of the gauge

manifold.
