Vacuum Pump

Vacuum Pump:

VACUUM PUMP
The vacuum pump is used to purge air and moisture from the inside of the refrigeration system by evacuation, thereby ensuring proper functioning of the air conditioner system.
Check the vacuum pump to see that the vacuum pump capacity is greater than -100.0 kPa (-750 mmHg, -29.53 in HG).

Vacuum Pump Procedure:

PERFORMANCE CHECK
1. Connect the vacuum gauge to the system.
2. Run the vacuum pump, and check to see that the needle pointers of the gauge manifold and vacuum gauge move smoothly, indicating a similar value.
3. After running the vacuum pump for two or three minutes, read the vacuum gauge. The measured value indicates the capacity of the vacuum pump.
