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 foundation for the equipment.
• Allow 6" clearance at rear and sides for proper air circulation and ease of maintenance
and /or service should they be required. Allow 24" clearance at top to allow for
removal of the Auger.

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) The flake size is adjustable to small (fine flakes), medium, and large (coarse flakes)
size. The adjustment is made by rotating the Cutter Head on the Auger Pin. The unit

WARNING
1. Electrical connection must be made in accordance with the instructions on a
“WARNING” tag provided with the pig tail leads in the Junction Box.
2. This icemaker requires a ground that meets the national and local electrical
code requirements. To prevent possible electrical shock to individuals or
extensive damage to the equipment, install a proper ground wire to the
icemaker.
• The white lead must be connected to the neutral conductor of the power source.
Miswiring results in severe damage to the icemaker. See Fig. 3.
• 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.

• External filters, strainers or softeners may be required depending on the water quality.
•
Water supply inlet is 1/2" female pipe thread (FPT).
Note: On water-cooled model, two water supply inlets are provided. One is
for ice making water, and the other is for cooling water.
•
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 and a maximum of 113 PSIG. If
the pressure exceeds 113 PSIG, the use of a pressure reducing valve is required.
• Drain outlet for icemaking is 3/4" FPT. The icemaker drain and the condenser drain
piping connections must be made separately from the bin drain.
Note: On water-cooled model, a 3/8" FPT is provided for the cooling water 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
2 vertical inches should be between the end of the drain pipe from the icemaker or the ice
bin and the floor drain.
• 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.

“LIME-A-WAY” (Economics Laboratory, Inc.) with 0.8 gal. of water.
This is a minimum amount. Make more solution, if necessary.
Sanitizingsolution: 2.5 fl. oz. of a 5.25% sodium hypochlorite solution (chlorine bleach)
with 5 gal. of water.
IMPORTANTIMPORTANT
IMPORTANTIMPORTANT

15) Remove the Front Panel.
16) Move the Flush Switch to the “FLUSH” position to drain the cleaning solution.
17) Move the Flush Switch to the “ICE” position.
18) Replace the Front Panel in its correct position.
19) Open the Water Supply Line Shut-off Valve, and supply water to the Reservoir.

19
20) Turn off the power supply when the Gear Motor starts.
21) Drain out all water from the water line. See 4) through 7).
<STEP3>
Use 3/4 gal. of the sanitizing solution to sanitize the icemaker.
1) Close the Water Supply Line Shut-off Valve.
2) Remove the Control Water Valve by releasing the Fitting Nut.
3) Remove the Cover of the Reservoir.
4) Fill the Reservoir with the sanitizing solution.
5) Replace the Cover of the Reservoir and the Control Water Valve in their correct

<STEP4>
Use the sanitizing solution to sanitize removed parts.
1) Remove the Thumbscrew securing the Bin Control Switch on the Chute Assembly.
2) Remove the Band connecting the Spout with the Chute Assembly, and take out the
Chute Assembly from the icemaker.
3) Remove the Gasket at the bottom of the Ice Chute and another at the Spout.
