C. Location  
WARNING  
This icemaker is not intended for outdoor use. Normal operating ambient  
temperature should be within +45°F to +100°F (+7°C to +38°C); Normal  
operating water temperature should be within +45°F to +90°F (+7°C to +32°  
C). Operation of the icemaker, for extended periods, outside of these normal  
temperature ranges may affect production capacity.  
For best operating results:  
* The icemaker should not be located next to ovens, grills or other high heat producing  
equipment.  
* Level the icemaker from side to side and front to rear by adjusting the legs. The location  
should provide a firm and level foundation for the equipment.  
* Avoid a site where dripping is not allowed.  
* This icemaker will not work at subfreezing temperatures. To prevent damage to the water  
supply line, drain the icemaker when air temperature is below zero.  
7
 
* The icemaker requires no clearance at either side. But allow enough space at rear for  
water supply and drain connections, at least 12” (approx. 30 cm) clearance at front, and  
at least 0.6” (approx. 15 mm) clearance at top for maintenance.  
D. Electrical Connection  
WARNING  
THIS APPLIANCE MUST BE GROUNDED.  
This icemaker requires a ground that meets the national and local electrical  
code requirements. To prevent possible severe electrical shock injury to  
individuals or extensive damage to equipment, install a proper ground wire  
to this icemaker. Remove the plug from the electrical outlet before any  
maintenance, repairs or cleaning is undertaken.  
CAUTION  
The GREEN ground wire in the factory-installed power cord is connected to  
a screw on the bracket where the cord enters the machine. If it becomes  
necessary to remove or replace the power cord, be sure to connect the power  
cord’s ground wire to this screw upon reattachment.  
* This icemaker must be plugged into an independent power receptacle which has enough  
capacity. The maximum allowable voltage variation should not exceed 10 percent of the  
nameplate rating. See the Nameplate.  
* Usually an electrical permit and services of a licensed electrician are required.  
E. Set Up
