Noise problem
○
Compressor noise
1>. The working of motor and piston motion will cause noise when compressor working. So if noise is steady
and not exceeds 42 dB, it
’
s normal. If noise is not steady or very high, it
’
s compressor fault and it should
be maintained or replaced.
2>. If compressor
’
s shock absorption rubber is hardening or damaged, or fixing screw of compressor is too
tight or loose, it will cause noise. The settlement is to change new shock absorption rubber or adjust
fixing screws.

1>. The running of the fan motor will cause noise because the vane circumvolve in high speed and the airflow.
Normal fan motor and airflow should not exceed 32 dB.
2 >. If the noise is extremely big , there maybe the fan
