I personally tested with fluorescent flashlight. According to the chief words really shine, no fake this process. 4 words, where, where bright 

Note refrigerant note: learn to watch

Blue is low voltage meter, red is high voltage meter

Blue low pressure meter index:

Idle speed: low voltage should not exceed 30PSI, that is, we often say 2KG

Red high pressure meter index:

Idle speed: high pressure must not exceed 220PSI, that is, we often say 15KG

Problems of poor cooling after common refrigerant filling

1 the index of the high voltage meter is too high and the index of the low pressure meter is normal

This situation is definitely not good refrigeration, serious compressor abnormal sound pressure will be too high, compressor overload operation system with air conditioning

The method eliminates the excess refrigerant and reduces the pressure to 220PSI (15KG)

2 low pressure meter index is high, high pressure meter index is normal

In this case, the cooling effect will certainly not be good. If the components are normal, the air will cause low voltage.

The solution is evacuated again, evacuated and refilled refrigerant

The normal pressure range is:

Idle speed: less than 1.2-2KG in high voltage 12-15KG

Speed up: high pressure goes up, low goes down
