WARNING
• Only qualied service technicians should install this kit to reduce the risk of death, electric shock, serious injury,
or re.
• Icemaker is heavy. Use care when lifting or positioning. Work in pairs when needed to prevent injury or damage.
• No installation or service should be undertaken until the technician has thoroughly read these instructions. Failure
to follow these instructions will adversely affect safety, performance, component life, and warranty coverage.
• Before Servicing: Move the control switch to the "OFF" position and turn off the power supply. Place the
disconnect in the "OFF" position. Lockout/Tagout to prevent the power supply from being turned back on
inadvertently. Control switch in "OFF" position does not de-energize all loads.
• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after the
icemaker is serviced. Make sure that none have fallen into the dispenser unit/ice storage bin.
• Make sure all food zones in the icemaker and dispenser unit/ice storage bin are clean after service.
• Protect the oor when moving the icemaker to prevent damage to the oor.
• Wear proper PPE (personal protection equipment) when executing these procedures.
• To reduce the risk of electric shock, do not touch the control switch with damp hands.
• The manufacturer cannot be held responsible for injury or damage resulting from improper, incorrect, and
unreasonable use or installation.
NOTICE
• Do not use the frame to lift the icemaker. Lift the icemaker at the base or use a duct jack to lift the upper icemaker
on top of the lower icemaker
• Up to three icemakers total (including the bottom icemaker) can be stacked.
Double Stacked: IM-500SAB × 2, Stacking Kit HS-5530 × 1
Triple Stacked: IM-500SAB × 3, Stacking Kit HS-5530 × 2
• The bin control switch on the lowest icemaker controls all icemakers. The bin control switch and switch mount
must be removed from the upper icemakers. Misconnection or no connection may cause damage to the
icemakers, resulting in icemaker failure or damage.
• Allow 6" (15 cm) clearance at rear, left side, and top (upper icemaker), and 12" (30 cm) clearance at right side for
proper air circulation and ease of maintenance and/or service should they be required.
New Lower Icemaker Installation Instructions
1) Follow the Instruction Manual's installation instructions through "II.D. Setup."
When complete, continue to step 2.
Note: If installing an upper icemaker on an existing lower icemaker,
skip to step 2.

Ice Chute
15) Place the new ice chute provided in this kit in position as shown in Fig. 8. Secure the rear of the ice chute to the
upper icemaker rear rail frame (bin control mounting bracket holes) with the new thumbscrews provided in this kit.
Secure front of the ice chute to the upper icemaker front rail frame (cube guide mounting hole) with the cube guide
thumbscrew removed in step 13. Conrm that the front of the ice chute clips over the front rail frame of the upper
icemaker and that the drain pan is not sitting on top of the ice chute. NOTICE! Conrm the drain pan is not sitting
on top of the new ice chute.
16) Stack the upper icemaker on top of the lower icemaker. Use of a duct jack may be required. See Fig. 9.
WARNING! Icemaker is heavy. Use care when lifting or positioning. Work in pairs when needed and use a duct
jack if available to prevent injury or damage.
17) Once in place, make the front, rear, and side panels ush to the lower icemaker. See Fig. 9.
18) At the rear of the icemakers, locate the upper and lower icemakers rear mounting holes. See Fig. 9. To prevent plastic
shavings from entering the ice storage bin area during drilling, place a large pan or cloth under the icemakers rear
mounting holes. Using the icemakers upper or lower mounting hole as a guide, drill a 3/8" (10 mm) hole down or up
through the top plastic spacer between the upper and lower icemaker. See Fig. 10.
19) Secure the upper icemaker to the lower icemaker using one of the hex bolts w/washer and nuts provided in this kit.
