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
theicemaker,forextendedperiods,outsideofthesenormaltemperatureranges
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
supplyline, drainthe icemaker when air temperature is belowzero.
* 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.
*TheAM-150BAFicemakerrequires2” (approx.5cm)clearanceateitherside. Allowenough
space atrear for water supplyand drain connections,atleast 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 theTop Panel.
1) Unpack the icemaker, and removeall 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-
rear directions (when installed with or without legs). See Fig.
2.
4) When installing the unitwithout legs, the perimeter where the
machine touches the counter should be sealed with silicone
to prevent water from leaking under the icemaker.
5) When installing the unit withlegs on the bottom, use the four
accessory legs adjustable from 6” (15.2 cm) to 7” (17.8 cm).
Screw thelegstightly 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
thisicemaker. Removetheplugfromthemainssocketbeforeanymaintenance,
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 supplyis OFF, or if the pressure is below10 PSIG (0.7bar), the
recommended water pressure. Stop the icemakeruntilproper water pressure
is resumed.
CAUTION
1. A brass fitting for the water supply line connectionis 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 stillto prevent overtightening and damage to the plastic threads.
* Water supply inlet for the icemaker is 1/2” female pipe thread (FPT).
Note: On water-cooledmodel,twowatersupplyinletsareprovided. Oneisfortheicemaker
(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 onlyto a potable watersupply.
* 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
icemakerdrainandthecondenserdrainpipingconnectionsmustbemadeseparately.
* 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 odorfrom flowing back into the Storage Bin.

[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 usinga neutral cleaner. Rinse
thoroughlyaftercleaning.
5. The Storage Bin is for ice use only. Do not store anything else in the Bin.

2. MAINTENANCE
IMPORTANT
Thisicemakermustbemaintainedindividually,referringtotheinstructionmanual
and labels provided with the icemaker.
1) Exterior
To keep the exterior clean, wipe occasionallywitha clean and soft cloth. Use a damp
cloth containinga neutral cleaner to wipe off all oilor dirt build-up.
2) Air Filter
Aplastic 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.
