This icemaker is not intended for outdoor use. Normal operating ambient
temperature should be within +45°F to +100°F; Normal operating water
temperatureshouldbewithin+45°Fto+90°F. Operationoftheicemaker,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 foundation for the equipment.
•Allow6"clearanceatrear,sidesandtopforproperaircirculationandeaseofmaintenance

2.Thisicemakerrequiresagroundthatmeetsthenationalandlocalelectrical
code requirements. To prevent possible electrical shock to individuals or
extensive damage to the equipment, install a proper ground wire to the
icemaker.
• Onthreephase models,theVoltageTapSwitch intheunitshouldbe positionedtomatch
incoming voltage at start-up. See Fig. 6a
• On single phase models only, the white lead must be connected to the neutral conductor
of the power source. Miswiring results in severe damage to the icemaker. See Fig. 6b.
• This icemaker must have a separate power supply or receptacle of proper capacity. See
the Nameplate.
• The opening for the power supply connection is 7/8" DIA to fit a 1/2" trade size conduit.
• Usually an electrical permit and services of a licensed electrician are required.

The condenser unit must be positioned in a permanent site under the following guidelines.
• A firm and flat site.
• A dry and well ventilated area with 24" clearance on both front and rear for ease of
maintenance and service should they be required.
• Normal condenser ambient temperature: -20°F to +122°F. Temperatures not within this
operating range may affect the production capacity of the icemaker.
• The maximum line length for the standard refrigerant charge is 66 feet. Should an
installationrequirealongerlinelength,pleasecall1-800-233-1940forrecommendations
concerning the correct additional refrigerant charge to be added.

as shown in the illustration. See Fig. 8.
Note: Locate the Legs symmetrically.
2) The Legs have eight mounting holes. Secure the Legs with eight bolts (not included).
3) Install enough length of two copper tubings provided with Aeroquip couplings between
the icemaker and the condenser unit. The two copper tubings should be insulated
separately. See Fig. 9.
• A connector kit “OS-QUICK” is available for field-fabricated lines from HOSHIZAKI
AMERICA.
•R-404Aprechargedtubingkits,availableasoptionalequipmentalsofromHOSHIZAKI
AMERICA, are recommended.
4) Line sets fabricated in the field should be evacuated through the charging ports on the
Aeroquip couplings and charged with R-404A refrigerant vapor to a pressure of
15-30 PSIG.
Note: Factory fabricated tubing kits are precharged and do not need to be evacuated.
5)Removethe plastic caps protecting thecouplings. Attachthetwo refrigerant lines to the
male couplings on the icemaker and the remote condenser unit. Each refrigerant line
must be connected as follows:
Icemaker discharge refrigerant line - 1/2" OD tubing to “DIS” of condenser unit
Icemaker liquid refrigerant line - 3/8" OD tubing to “LIQ” of condenser unit
Note: Care should be taken that the unit, line set and Condenser contain the same type
refrigerant prior to making connections. Mixing of refrigerants will result in
improper operation and possible damage to the refrigeration system. Make the
connections at the remote condenser first and then at the icemaker.
