6) Open the high-side valve on the gauge manifold, and accurately measure in the
liquid charge. Close the valve on the charging cylinder before closing the high-side
manifold valve. Any remaining liquid in the line can be charged into the low side.
Note: Always charge in the liquid stage, as many refrigerants are blends and vapour
charging will affect the blend consistency.
7) Turn on the ice dispenser. 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.
3. COMPRESSOR
1) Unplug the ice dispenser or disconnect the power source.
2) Remove the front panel (lower) and rear access panel.
3) Recover the refrigerant and store it in a proper container, if required by an applicable
law (See “2. [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.
