II. Installation Instructions
A. 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.
• Remove the protective plastic film from the panels. If the icemaker is exposed to the sun
or to heat, remove the film after the icemaker cools.
• See the nameplate on the left side panel, and check that your voltage supplied
corresponds with the voltage specified on the nameplate.
B. Location
1. General
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.

2. Built-In Installation Site
IMPORTANT
1. Do not let the weight of the counter rest on the icemaker.
2. 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.

c) Fabrication of Overlay Panel
1) Manufacture the overlay panel to the width, height and thickness per your model's
specification (AM-50BAE-DS or AM-50BAE-ADDS). See the previous two pages for
specifications.
2) Rout a channel at the bottom of the overlay panel to the proper dimensions. See "(C)
Routed Area" in the specification drawing.
3) Drill six 1/4" diameter (hardwood may require slightly larger diameter) holes 3/8" deep
in the locations designated in the specification drawing. See "(A) Threaded Inserts" and
"(B) Threaded Inserts".
CAUTION
Use care when drilling holes for mounting hardware. All drilled holes must be
straight and drilled to the correct diameter and depth.
4) Screw the six (6) threaded wood inserts into the predrilled 1/4" holes in the back of the
overlay panel. Make sure that the inserts are threaded straight and that the tops of the
inserts are flush to the overlay panel surface. Otherwise, the overlay panel cannot be
properly fastened to the door.
5) Mount the door handle hardware. Hoshizaki recommends that the door handle
hardware be mounted on the edge opposite of the door hinge side. Countersunk screw
heads are required to ensure that the hardware fasteners do not interfere with the
overlay panel fitting flush with the door.
6) Remove the hinge stop pin from hinge (B), then remove the door from hinge (A). If you
are leaving the door right-hinged, go to step 8. Otherwise proceed to step 7.

c) Remove hinge (B) and reattach on the left side. Move the two screws from the left
side and reattach on the right side.
d) Turn the top panel 180° from its previous position. This brings the notch that was
previously in the right rear to the left front. Hook the rear part of the panel on the
body, and secure the front with the two screws removed in step 7a.
