II. 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.  
WARNING  
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  
WARNING  
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, outside 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.  
* Avoid 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, at least 12” (approx. 30 cm) clearance at  
front, and at least 0.6” (approx. 15 mm) clearance at top for maintenance.  
* The AM-150BAF icemaker requires 2” (approx. 5 cm) clearance at either side. Allow enough  
space at rear for water supply and drain connections, at least 12” (approx. 30 cm) clearance  
at front, and at least 0.6” (approx. 15 mm) clearance at top for maintenance.

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-to-  
Max. 0.4” (1 cm)  
rear directions (when installed with or without legs). See Fig.  
2.  
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.  
Tapped 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  
WARNING  
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.

5. WATER SUPPLY AND DRAIN CONNECTIONS  
WARNING  
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 Valve 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 113  
PSIG (7.5 bar). If the pressure exceeds 113 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 condenserdrain pipingconnections 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 Storage Bin. Provide a trap  
in the bin drain line to prevent odor from flowing back into the Storage Bin.  
7
 
* 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.

[b] STORAGE BIN, SLOPE, SCOOP, ETC.  
IMPORTANT  
1. Wash your hands before removing ice. Use the Plastic Scoop provided to  
remove ice.  
2. Keep the Scoop clean. Clean it by using a neutral cleaner at least once a  
day, and rinse thoroughly.  
3. Close the Bin Door after removing ice to prevent entrance of dirt, dust or  
insects into the Bin.  
4. Clean the Bin Liner at least once a month by using a neutral cleaner. Rinse  
thoroughly after cleaning.  
5. The Storage Bin is for ice use only. Do not store anything else in the Bin.  
6. Keep the area around the icemaker clean. Dirt, dust or insects in the icemaker  
could cause electrical damage to the equipment or harm to individuals.  
1) Remove the Front Panel (Lower), and move the Control Switch on the Control Box to the  
“OFF” position.  
2) Unplug the icemaker.  
3) Open the Bin Door, and remove ice from the Storage Bin.  
4) Remove the Slope by bending its center carefully and releasing it from the two Slope  
Shafts. Take out the Slope from the Storage Bin.  
5) Thoroughly clean and sanitize the Storage Bin, Slope, Scoop and any parts normally  
accessible from the Storage Bin.  
Separator  
6) Remove each Separator by lifting it to the  
horizontal position and pushing it hard inward.  
Remove all the Separators in the same way,  
and clean and sanitize them.  
7) Disconnect the Suction Tube from the Water  
Tank to drain the Tank.

2. MAINTENANCE  
IMPORTANT  
This icemaker must be maintained individually, referringto the instruction manual  
and labels provided with the icemaker.  
1) Exterior  
To keep the exterior clean, wipe occasionally with a clean and soft cloth. Use a damp  
cloth containing a neutral cleaner to wipe off all oil or dirt build-up.  
2) Air Filter  
A plastic mesh air filter removes dirt or dust from the air, and keeps the Condenser  
from getting clogged. As the filter gets clogged, the icemaker’s performance will be  
reduced. Check the filter at least twice a month. When clogged, use warm water and  
a neutral cleaner to wash the filter.  
3) Condenser  
Check the Condenser once a year, and clean if required by using a brush or vacuum  
cleaner. More frequent cleaning may be required depending on the location of the  
icemaker.
