Note: Always charge in the liquid stage, as many refrigerants are blends and vapour
charging will affect the blend consistency (e.g. R404A).
7) Turn on the icemaker. Release the high-side access connector, and allow pressure
in the charging line to slowly enter the low side of the system. Cap off the high-
side access valve. When pressure reduces on the low side, disconnect the low side
charging line and cap off the access valve.
8) Always cap the access valves to prevent a refrigerant leak.
9) Always thoroughly leak test all joints and valve caps.
10) Avoid charging large quantities of liquid into the low side in case of damage to the
compressor.
2. COMPRESSOR
1) Unplug the icemaker or disconnect the power source.
2) Remove the top, front and right side panels.
3) Recover the refrigerant and store it in a proper container, if required by an applicable
law (See “1. [b] REFRIGERANT RECOVERY”).
4) Remove the terminal cover on the compressor, and disconnect solderless terminals.
5) Disconnect the discharge and suction pipes using brazing equipment.
6) Remove the hold-down bolts, washers and rubber grommets.
7) Slide and remove the compressor. Unpack the new compressor package.
8) Attach the rubber grommets of the previous compressor.
9) Clean the suction and discharge pipes with an abrasive cloth/paper.
