III. INSTALLATION AND OPERATING INSTRUCTIONS
1. CHECKS BEFORE INSTALLATION
* Visually inspect the exterior of the shipping container , and any severe damage noted should
be reported to the carrier.
W ARNING
1. Remove shipping tape(s) and packing as follows. If any left in the icemaker ,
it will not work properly .
2. Do not lift or carry the unpacked icemaker by using the brass fitting for water
supply at the rear of the unit. The plastic threads may be damaged.
IMPORTANT
1. Remove the shipping tapes holding the Door and Separator .
2. Ensure all components, fasteners and thumbscrews are securely in place.
* Remove the package containing accessories.
* Check that refrigerant lines do not rub or touch lines or other surfaces.
* Check that the Compressor is snug on all mounting pads.
* See the Nameplate on the upper right part of the Left Side Panel, and check that your
voltage supplied corresponds with the voltage specified on the Nameplate.

2. LOCATION
W ARNING
This icemaker is not intended for outdoor use. Normal operating ambient
temperature should be within 50°F (10°C) to 100°F (38°C); Normal operating
water temperature should be within 41°F (5°C) to 90°F (32°C). Operation of
the icemaker, for extended periods, out side of these normal temperature ranges
may affect production capacity.
For best operating results:
* The icemaker should not be located next to ovens, grills or other high heat producing
equipment.
* The location should provide a firm foundation for the equipment. Level the icemaker from
side to side and front to rear.
* A void a site where dripping is not allowed.
* This icemaker will not work at subfreezing temperatures. To prevent damage to the water
supply line, drain the icemaker when air temperature is below zero.
* The AM-100BAE icemaker requires no clearance at either side. But allow enough space at
rear for water supply and drain connections and at least 12” (approx. 30 cm) clearance at
front.
* The AM-150BAF icemaker requires 2” (approx. 5 cm) clearance at either side. Allow enough
space at rear for water supply and drain connections and at least 12” (approx. 30 cm)
clearance at front.
12
3. SET UP IMPORTANT
Do not place heavy objects exceeding 33 lbs (15 kg) on the Top Panel.
1) Unpack the icemaker , and remove all shipping cartons, tapes
and packing BEFORE operating the unit.
2) Position the icemaker in a selected site. Clean the interior
with soap and water and rinse thoroughly .
3) Level the icemaker in both the left-to-right and the front-torear directions (when installed with or without legs). See Fig.
2.
4) When installing the unit without legs, the perimeter where the
machine touches the counter should be sealed with silicone
to prevent water from leaking under the icemaker .
Max. 0.4” (1 cm)
Fig. 2
T apped Hole
(Leg Mounting)
5) When installing the unit with legs on the bottom, use the four
accessory legs adjustable from 6” (15.2 cm) to 7” (17.8 cm).
Screw the legs tightly into the tapped holes in the base (see
Fig. 3). Handle the icemaker carefully not to damage the
exterior.

4. ELECTRICAL CONNECTIONS
W ARNING
THIS APPLIANCE MUST BE GROUNDED.
This icemaker requires a ground that meets the national and local electrical
code requirements. To prevent possible severe electrical shock injury to
individuals or extensive damage to equipment, install a proper ground wire to
this icemaker. Remove the plug from the mains socket before any maintenance,
repairs or cleaning is undertaken.
* This icemaker must be plugged into the separated power receptacle which has enough
capacity . The maximum allowable voltage variation should not exceed ± 10 percent of the
nameplate rating. See the Nameplate.
* Usually an electrical permit and services of a licensed electrician are required.
13
5. WATER SUPPLY AND DRAIN CONNECTIONS
W ARNING
To prevent damage to the freezer mechanism, do not operate this icemaker
when the water supply is OFF , or if the pressure is below 10 PSIG (0.7 bar), the
recommended water pressure. Stop the icemaker until proper water pressure
is resumed.
CAUTION
1. A brass fitting for the water supply line connection is attached to the 3/4” BSP
plastic threads to avoid cross-threading of the Water V alve possibly resulting
in leaks. The brass fitting allows connection of a 1/2” FPT that should be
connected to the potable water supply line.
2. While making the water supply line connection, use a wrench to hold the
brass fitting still to prevent overtightening and damage to the plastic threads.
* Water supply inlet for the icemaker is 1/2” female pipe thread (FPT).
Note: On water-cooled model, two water supply inlets are provided. One is for the icemaker
(1/2” FPT), and the other is for the water-cooled condenser (1/2” FPT).
* The brass fitting is attached as shown in Fig. 4. The fitting size is a 1/2” FPT and must be
connected only to a potable water supply .
* A water supply line shut-off valve and drain valve must be installed.
* Water supply pressure should be a minimum of 10 PSIG (0.7 bar) and a maximum of 1 13
PSIG (7.5 bar). If the pressure exceeds 1 13 PSIG (7.5 bar), use a pressure reducing valve.
* Drain outlet for icemaker dump is 3/4” FPT .
Note: On water-cooled model, a 3/8” FPT is provided for the condenser drain outlet. The
icemaker drain and the condenser drain piping connections must be made separately .
* Drain must be 1/4” fall per foot (2 cm fall per meter) on horizontal runs to get good flow.
* Keep a more than 2 vertical inch (5 vertical cm) air gap between the drain pipe end and the
sink.
* The drain pipe must be so laid as to prevent a backflow into the S torage Bin. Provide a trap
in the bin drain line to prevent odor from flowing back into the Storage Bin.
14
* A plumbing permit and services of a licensed plumber may be required in some areas.
* This icemaker should be installed in accordance with applicable national, state and local
regulations.
