Be careful not to mix moisture and

contamination into the pipe

Moisture

 and 

contamination

in the pipe is a cause of
trouble.

Air purge

Always use a 

vacuum pump

 to purge air.

Refrigerant charge

Do it always from the 

liquid

 phase

side. 

Don't charge from the 

gas

 phase side.

Compressor oil is changed

Be careful to handle synthetic oil, since it

resolves easily by moisture and contamination.

Don't mix new synthetic oil and mineral oil.

It may cause trouble.

We developed new synthetic oil, since HFC

refrigerant doesn't dissolve in mineral (for R22)oil.
