III. Installation and Operating Instructions
1. Checks Before Installation
* Visually inspect the exterior of the shipping container and report any severe damage to
the carrier.
WARNING
Remove shipping tape(s) and packing as follows. If any are left in the
icemaker, it will not work properly.
IMPORTANT
1. Remove shipping tape holding the door.
2. Ensure all components, fasteners and thumbscrews are securely in place.
* Remove the package containing accessories. Remove shipping tape holding the separator.
* 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
Normal operating ambient temperature should be within 45°F (7°C) to 100°F
(38°C); Normal operating water temperature should be within 45°F (7°C) to
95°F (35°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 freezing.
* This icemaker requires no clearance on either side. But allow enough space at rear for
water supply and drain connections and at least 15" (approx. 38 cm) clearance at front.

3. Setup
1) Unpack the icemaker, and remove all shipping cartons, tapes and packing BEFORE
operating the unit. Be careful not to damage the exterior panels when handling the
icemaker.
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.
4) The perimeter where the machine touches the floor should be sealed with silicone for
sanitation.
Built-In Installation
[a] Checking the Installation Site
Ensure a 15" (381 mm) wide space for building in the icemaker.
1) To build in between two units:
Min. 34"
15"
AM-50BAE
2) To build in between a unit and a wall or a
tall unit:
Secure
Fig. 2
Secure the counter to the wall with a bracket
or the like. Ensure a 15" (381 mm) wide, min.
34" (864 mm) high space for the icemaker.
Min. 32"
15"
AM-50BAE-AD
Fig. 1
For the AM-50BAE-AD ensure a min. 32"
(814 mm) high space for the icemaker.
IMPORTANT
Do not let the weight of the counter rest

3) To build in between a unit and an open
space:
Cabinet
4) To build into a corner:

Oven
Icemaker
Fig. 4
Do not build in the icemaker in a corner where
the door will hit other equipment such as an
oven handle or where the icemaker cannot
be pulled out for service.
U1VA6060209
[b] Building in the Icemaker
1) Make water supply and drain connections.
2) Plug in the icemaker.
3) Build in the icemaker:
Slowly push the lower part of the icemaker into place. Beware of adjacent equipment.
IMPORTANT
While building in the icemaker, do not damage the water supply and drain
connections or the power cord.

4. Electrical Connections
THIS APPLIANCE MUST BE GROUNDED.
This icemaker requires a ground that meets 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.
WARNING
* This icemaker must be plugged into a 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.
