See 11 3 Tools Specifically for R410A 11 5 1 Procedure for Replacing Compressor 1 Recovering refrigerant e Anyremaining refrigerant inside the unit should not be released to the atmosphere but recovered using the refrigerant recovery unit for R410A e Do notreuse the recovered refrigerant since it will contain impurities 2 Replacing Compressor e Soon after removing seals of both discharge and suction tubes of the new compressor replace it quickly 3 Checking for sealing e Use nitrogen gas for the pressurized gas and never use a refrigerant other than R410A Also do not use oxygen or any flammable gas 4 Evacuation e Use a solenoid valve installed vacuum pump so that even if power is cut off in the middle of evacuation of air due to a power interruption the valve will prevent the pump oil from flowing back e The equipment may be damaged if moisture remains in the tubing thus carry out the evacuation thoroughly e When using a vacuum pump with exhaust air volume more than 0 883 cu ft min and ultimate vacuum pressure rate of 50 micron Hg Standard time for evacuation 1 Recover refrigerant OK 2 Replace compressor OK 3 Check for sealing OK 4 Evacuation OK b Recharge Length of tubing Less than 33 ft 10 m More than 33 ft 10 m More than 10 minutes More than 15 minutes 64 5 Recharging Be sure to charge the specified amount of refrigerant in l
