The icemaker unit is provided with two Refrigerant Access Valves on the low-side and
high-side lines.  Recover the refrigerant from the Access Valves and store it in an ap-
proved container.  Do not discharge the refrigerant into the atmosphere.

1) Attach Charging Hoses, a Service Manifold and a Vacuum Pump to the system.  For

models with the Line Valve, be sure to connect Charging Hoses to both high-side
and low-side lines, or the high-side line cannot be evacuated because of the Line
Valve.

2) Turn on the Vacuum Pump.

3)  Allow the Vacuum Pump to pull down to a 29.9" Hg vacuum.  Evacuating period

depends on pump capacity.

4) Close the Low-side Valve and High-side Valve on the Service Manifold.

5) Disconnect the Vacuum Pump, and attach a Refrigerant Service Cylinder to the Low-

side line.  Remember to loosen the connection, and purge the air from the Hose.
See the Nameplate for the required refrigerant charge.  Hoshizaki recommends only
virgin refrigerant or reclaimed refrigerant which meets ARI Standard No. 700-88 be
used.

6) Open the Low-side Valve.  Do not invert the Service Cylinder.  A liquid charge will

damage the Compressor.

7) Turn on the icemaker when charging speed gets slow.  Turn off the icemaker when

the Low-side Gauge shows approximately 0 PSIG.  Do not run the icemaker at
negative pressures.  Close the Low-side Valve when the Service Cylinder gets
empty.

8) Repeat the above steps 4) through 7), if necessary, until the required amount of

refrigerant has entered the system.

9) Close the two Refrigerant Access Valves, and disconnect the Hoses and Service

Manifold.

10) Cap the Access Valves to prevent a possible leak.
