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 min.)

3) When the low pressure gauge indicates 30 inHg

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

and close the high pressure valves of the gauge

manifold.
