Setup
Ice Storage Bin and Icemaker Setup
WARNING
The installer must ensure the ice storage bin is compatible with the icemaker, and the dispenser unit/ice storage bin and icemaker are properly attached and secured.

1. Unpack the ice storage bin and attach the 4 adjustable legs provided (bin accessory) to the bottom of the ice storage bin.
2. Position the ice storage bin in its permanent location.
3. Place the icemaker on top of the storage bin.
4. Secure the icemaker to the storage bin using the 2 mounting brackets and the bolts provided.
5. Level the icemaker and storage bin in both the left-to-right and front-to-rear directions. Adjust the storage bin legs to make the icemaker level.
6. Icemaker: Replace the panels in their correct positions.

Bin Control Installation
NOTICE
Before operating the icemaker, the bin control must be installed. Failure to properly install the bin control could result in ice backup icemaker damage

1. If not already removed, remove the front Panel top panel, and right side panel.

2. Remove the bin control from the compressor compartment.

3. Remove the bin control extension bracket from the upper taper collar and lower it into the access hole and secure it on the lower taper collar.
   Note: Be sure to secure the Bin control extension bracket onto the lower taper collar.
   

4. Remove the switch mount and thumbscrews from the accessory bag. Open the ice storage bin door and install the switch mount to the bin control extension bracket.

5. Route the bin control cable up through the switch mount and the capillary ring in the bin control extension bracket, then using the thumbscrews from the accessory bag, install the bin control to the switch mount.

6. Route the bin control cable through the wire saddles across the bottom of the compressor base, then up to the control box and through the control box wire grommet and into the control box. Connect the bin control cable to the K4 bin control connector (red).
   Note: Be sure the bin control cable is clear of the fan motor, fan blade, discharge line, crankcase heater, and compressor.

7. Using nylon ties provided in the accessory bag, secure the bin control cable to the wire bundle leading into the control box.

Electrical Connection

WARNING
For All Models

• Electrical connection must be hard-wired and must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or damage.

• The icemaker requires an independent power supply of proper capacity. See
  the nameplate for electrical specifications. Failure to use an independent power supply of proper capacity can result in a tripped breaker, blown fuse, damage to existing wiring, or component failure. This could lead to heat generation or fire.

• THE ICEMAKER MUST BE GROUNDED. Failure to properly ground the icemaker could result in death or serious injury.

• Electrical connection must be made in accordance with the instructions on the “WARNING” tag, provided with the pig tail leads in the junction box

• Usually an electrical permit and services of a licensed electrician are required.

• The maximum allowable voltage variation is ±10 percent of the nameplate rating.

• NOTICE! The main transformer’s voltage tap switch must be positioned to match incoming voltage at startup.

• The opening for the power supply connection is 7/8″ DIA to fit a 1/2″ trade size conduit.

Water Supply and Drain Connections

WARNING
Water supply and drain connections must be installed in accordance with applicable national, state, and local regulations.
NOTICE

• Normal operating water temperature should be within 45°F to 90°F (7°C to 32°C). Operation of the appliance, for extended periods, outside of this normal temperature range may affect appliance performance.

• Water supply pressure must be a minimum of 10 PSIG and a maximum of
  113 PSIG. If the pressure exceeds 113 PSIG, the use of a pressure reducing valve is required.

• To prevent damage to the appliance, do not operate the appliance when the water supply is off, or if the pressure is below 10 PSIG. Do not run the appliance until the proper water pressure is reached.

• External filters, strainers, or softeners may be required depending on water quality. Contact your local Hoshizaki Certified Service Representative or local Hoshizaki distributor for recommendations.

• A plumbing permit and services of a licensed plumber may be required in some areas.

• The icemaker drain line, ice storage bin drain line, and water-cooled condenser drain line must be run separately. The condensation drain line can be connected to the icemaker drain line or can be run separately.

• Drain lines must have 1/4″ fall per foot (2 cm per 1 m) on horizontal runs to get a good flow. A vented tee connection is also required for proper flow.

• Drain lines should not be piped directly to the sewer system. An air gap of a minimum of 2 vertical inches (5 cm) should be between the end of the drain pipes from the icemaker and condensation drain, ice storage bin, and water-cooled condenser and the floor drain.
