Compressor - Hoshizaki IM-240DNE Service Manual

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.
