Adding Refrigerant / System Charging:
To charge the system with cycling fans, observe sight
glass during the ice making cycle. When the fans cycle off, the sight glass should clear in 8 to 10 seconds.
 If it takes longer than 10 seconds to clear the glass, the unit is undercharge. Add refrigerant to
system at compressor suction port or the ¼” access fitting on suction line. (See Figure 4-6)
 If the glass clears in less than 8 seconds, the unit is overcharged. Remove refrigerant from system
following EPA standards.
Note: Do not charge to a full sightglass. Do not charge in a harvest cycle.
If packaged unit is totally out of refrigerant, add amount specified on machines nameplate.
