hand side of the rear panel.
Since this Nameplate is located on the rear panel of the
icemaker, it cannot be read when the back of the
icemaker is against a wall or against another piece of
kitchen equipment. Therefore, the necessary electrical
and refrigeration information is also on the rating label,
which can be easily seen by removing only the front
panel of the icemaker.
We reserve the right to make changes in specifications and design without prior notice.

This icemaker is not intended for outdoor use. Normal operating ambient
temperatureshould bewithin +45°F (7°C)to +100°F(38°C); Normal operat-
ingwatertemperatureshouldbewithin+45°F(7°C)to+90°F (32°C). Opera-
tion of the icemaker, for extended periods, outside of these normal tempera-
ture ranges may affect production capacity.
For best operating results:
• 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. Location
should provide a firm and level foundation for the equipment.
•Allow6"(15cm.)clearanceatrear andtopforeaseofmaintenanceand/orserviceshould

to a screw on the rear panel. If it becomes necessary to remove or
replace the power cord, be sure to attach the ground wire of the power cord
to this screw on the rear panel.
• This icemaker must have a separate power supply or receptacle of proper capacity. See
the Nameplate.
• Usually an electrical permit and services of a licensed electrician are required.

To prevent damage to the equipment, do not operate the icemaker when the
watersupplyisOFF,orifthepressureisbelow10PSIG(0.7bar). Donotrun
the icemaker until the proper water pressure is reached.
• Water supply inlet is 1/2" FPT.
Note:Onwater-cooledmodel,twowatersupplyinletsareprovided. Oneistheicemaking
water inlet, and the other (1/2" FPT) is the cooling water inlet.
• A water supply line shut-off valve and drain valve should be installed. A minimum of 3/8"
OD copper tubing is recommended for the water supply lines.
• Water supply pressure should be a minimum of 10 PSIG (0.7 bar) and a maximum of 113
PSIG(7.5bar). Ifthepressureexceeds113PSIG(7.5bar),theuseofapressurereducing
valve is required.
•Drainoutletforicemakerdumpis3/4"FPT. Thebindrainis3/4"FPT. Theicemakerdrain
andthe condenserdrain pipingconnections must bemade separatelyfrom thebin drain.
Note: On water-cooled model, a 1/2" FPT is provided for the condenser drain outlet.
• The drains must have 1/4" fall per foot (2 cm. per meter) on horizontal runs to get a good
flow.
• The drains should not be piped directly to the sewer system. An air gap of a minimum of
2 vertical inches ( 5 cm.) should be between the end of the drain pipe from the icemaker
or the ice bin and the floor drain.
• This icemaker should be installed in accordance with applicable national, state and local
regulations.
• A plumbing permit and services of a licensed plumber may be required in some areas.
• In some areas, a back flow preventer may be required in the cooling water circuit.
