• Shut-off valves and drain valves must be installed at both the condenser water supply inlet 
and condenser return outlet.
• Minimum water flow to the condenser is 4 GPM. 
• The pressure differential between the condenser water supply inlet and condenser return 
outlet must be no less than 10 PSIG.
• When using a glycol blend, the solution mixture should be less than 30% glycol.
• In order to maintain the proper high side pressure, the condenser water supply inlet 
temperature should not drop below 45°F (7°C) and the condenser return outlet 
temperature must be in the 104°F to 115°F (40°C to 46°C) range. Once the icemaker 
installation is complete, confirm the condenser return outlet temperature 5 minutes after a 
freeze cycle starts. If the condenser return outlet temperature is not in the proper range, 
use a flat blade screwdriver to rotate the adjustment screw on the water-regulating valve 
until the temperature is in the proper range (rotate counterclockwise to raise temperature 
or clockwise to lower temperature).

Separate piping to approved 
drain. Leave a 2-inch (5-cm) 
vertical air gap between the 
end of each pipe and the 
drain.
Be sure there is sufficient 
extra water supply line and 
drain line for the appliance 
to be pulled out for service.
