3. LOCATION WARNING This icemaker is not intended for outdoor use. Normal operating ambient temperature should be within +45°F to +100°F; Normal operating water temperature should be within +45°F to +90°F. Operation of the icemaker, for extended periods, outside of these normal temperature ranges may affect production capacity. For best operating results: Icemaker should not be located next to ovens, grills or other high heat producing equipment. Location should provide a firm and level

7. WATER SUPPLY AND DRAIN CONNECTIONS - See Fig. 10 WARNING To prevent damage to the pump assembly, do not operate the icemaker when the water supply is OFF, or if the pressure is below 10 PSIG. Do not run the icemaker until the proper water pressure is reached. Water supply inlet is 1/2" female pipe thread (FPT). A water supply line shut-off valve and drain valve should be installed. A ball valve is recommended for the shut-off valve. A type of valve other than a ball valve can have a ma
