This icemaker is not intended for outdoor use. Normal operating ambient
temperatureshouldbewithin+45°F to+100°F; Normaloperatingwatertem-
perature should be within +45°F to +90°F. Operation of the icemaker, for
extended periods, outside of these normal temperature ranges may affect
productioncapacity.
For best operating results:
•Icemaker should not be located next to ovens, grills or other high heat producing equip-
ment.
•Location should provide a firm and level foundation for the equipment.
•Allow 6" clearance at rear, sides and top for proper air circulation and ease of mainte-
nance and/or service should they be required.

Before operating the icemaker, the Bin Control Thermostat Bulb must be set
correctly.
5) Set the Bin Control Thermostat Bulb as follows. See Fig. 3.
(a) Take off the shipping tape securing the Thermostat Bulb Holder. Remove the Ther-
mostat Bulb Holder from the Shipping Hook by lifting it up and shifting to the right.
(b) Slide the Thermostat Bulb Holder down through the hole located in the bottom of the
icemaker until it is placed in the Bracket.
(c) Insert the Plug into the Receptacle on the Holder. Check to see that the Plug is
locked into the Receptacle.
6) Level the icemaker/Storage Bin in both the left-to-right and front-to-rear directions.
Adjust the Ice Bin Legs to make the icemaker level.
7) Replace the panels in their correct positions.

The condenser unit must be positioned in a permanent site under the following guidelines.
•Afirmandflatsite.
•Adry and well ventilated area with 24" clearance on both frontand rear for ease of main-
tenance 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.
•Themaximum line length for the standard refrigerant charge is 66 feet. Should an instal-
lation require a longer line length, please call 1-800-233-1940 for recommendations
concerning the correct additional refrigerant charge to be added.
Note: If the recommended guidelines of the installation are exceeded,
the icemaker performance may be reduced.

Nuts as shown in the illustration. See Fig. 6.
Note:LocatetheLegssymmetrically.
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
theicemakerandthecondenserunit. Thetwocoppertubingsshouldbe insulatedsepa-
rately. SeeFig.7.
•Prechargedtubingkits,availableas optionalequipmentfromHOSHIZAKIAMERICA,
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)Remove the plastic caps protectingthe couplings. Attach the tworefrigerant 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: Make the connections at the remote condenser first and then at the icemaker.

Note: On water-cooled model, a 3/8" FPT is provided for the condenser drain outlet.
•The drains must have 1/4" fall per foot 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
