See the nameplate for electrical and refrigeration specications. This nameplate is located
on 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 lower front panel of the icemaker.

We reserve the right to make changes in specifications and design without prior notice.

II. Installation and Operating Instructions

A. Checks Before Installation

IMPORTANT

1. Install in accordance with all applicable national, state, and local regulations.

2. Ensure all components, fasteners, and thumbscrews are securely in place
after installation.

3. Remove the shipping carton, tape, and packing material. If any are left in the
icemaker, it will not work properly.

1) Remove the panels to prevent damage when installing the icemaker. See "II.B. How to
Remove Panels."

2) Remove the package containing the accessories.

3) Remove the protective plastic lm from the panels. If the icemaker is exposed to the
sun or to heat, remove the lm after the icemaker cools.

4) Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the
fan blade turns freely.

5) Check that the compressor is snug on all mounting pads.

6) See the nameplate on the rear panel, and check that your voltage supplied corresponds
with the voltage specied on the nameplate.

C. Location

1. This icemaker is not intended for outdoor use. Normal operating ambient
temperature should be within +45°F to +100°F (+7°C to +38°C); Normal
operating water temperature should be within +45°F to +90°F (+7°C to
+32°C). Operation of the icemaker, for extended periods, outside of these
normal temperature ranges may affect icemaker performance.

2. This icemaker will not work at sub-freezing temperatures. To prevent
damage to the water supply line, drain the icemaker if the air temperature is
going to go below 32°F (0°C). See "III.D. Preparing the Icemaker for Long
Storage."

DT-400BAH-OS: Sunlight, direct and indirect, can have an effect on the
operation of the dispense sensors. If a problem is noticed, the machine should
be moved out of direct sunlight and/or farther away from any outside windows.

For best operating results:

CAUTION

IMPORTANT

• Icemaker should not be located next to ovens, grills, or other high heat producing
equipment.

• Avoid choosing a site where dripping is not allowed.

• Allow 6" (15 cm) clearance at rear, and top for proper air circulation and ease of
maintenance and/or service should they be required.

• Location should provide a rm and level foundation for the equipment.

D. Setup

1) Attach the four adjustable legs provided to the bottom of the icemaker.

2) Position the icemaker in the selected permanent location.

3) Level the icemaker in both the left-to-right and front-to-rear directions.
