Important Safety Information

WARNING Indicates a hazardous situation which could result in death or serious injury.
NOTICE
Indicates a situation which could result in damage to the appliance or property.
IMPORTANT
Indicates important information about the installation, use, and care of the appliance.

The appliance should be destined only to the use for which it has been expressly conceived. Any other use should be considered improper and therefore dangerous.
The manufacturer cannot be held responsible for injury or damage resulting from improper, incorrect, and unreasonable use. Failure to install, operate, and maintain the appliance in accordance with this manual will adversely affect safety, performance, component life, and warranty coverage and may result in costly water damage. To reduce the risk of death, electric shock, serious injury, or fire, follow basic precautions including the following:

• Only qualified service technicians should install and service the appliance.
• The appliance must be installed in accordance with applicable national, state, and local codes and regulations.
• The appliance 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 APPLIANCE MUST BE GROUNDED: The appliance is equipped with a NEMA 5-15 three-prong grounding plug to reduce the risk of potential shock hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualified electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not remove the ground prong from the plug and do not use an adapter plug. Failure to properly ground the appliance could result in death or serious injury.
• Do not use an extension cord.
• To reduce the risk of electric shock, do not touch the control switch or plug with damp hands. Make sure the control switch is in the “OFF” position before plugging in or unplugging the appliance.
• Do not use an appliance with a damaged power cord. The power cord should not be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result in electric shock or fire. To unplug the appliance, be sure to pull the plug, not the cord, and do not jerk the cord.
• Do not make any alterations to the appliance. Alterations could result in electric shock, injury, fire, or damage to the appliance.

WARNING, continued

• The appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
• Children should be properly supervised around the appliance.
• Do not climb, stand, or hang on the appliance or appliance door or allow children or animals to do so. Serious injury could occur or the appliance could be damaged.
• Be careful not to pinch fingers when opening and closing the door. Be careful when Opening and closing the door when children are in the area.
• Do not use combustible spray or place volatile or flammable substances near the appliance. They might catch fire.
• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance could cause harm to individuals or damage to the appliance.

NOTICE

• Protect the floor when moving the appliance to prevent damage to the floor.
• Follow the water supply, drain connection, and maintenance instructions carefully to reduce the risk of costly water damage.
• In areas where water damage is a concern, install in a contained area with a floor drain.
• Install the appliance in a location that stays above freezing. Normal operating ambient temperature must be within 45°F to 100°F (7°C to 38°C).
• If water collects in the bin and will not drain, turn off the appliance and close the water supply line shut-off valve. Call for service.
• Do not leave the appliance on during extended periods of non-use, extended absences, or in sub-freezing temperatures. To properly prepare the appliance for these occasions, follow the instructions in “IV. Preparing the Appliance for Periods of Non-Use.”
• Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction.
• Do not place more than 33 Ib. (15 kg) on the top panel.
• The ice storage bin is for ice use only. Do not store anything else in the ice storage bin.

F. Water Supply and Drain Connections – See Figs. 4 through 6
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.
  lf 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.

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

• The icemaker drain line and water-cooled condenser drain line (if applicable) must 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 water-cooled condenser (if applicable) and the floor drain.
