Product overview

The Hoshizaki KM-660MAJ-E is a 50 Hz air-cooled modular crescent ice maker with a stainless steel double-sided evaporator, CycleSaver design and EverCheck alert system. It produces up to 280 kg per 24 hours at 21°C air / 10°C water, with 262 kg per 24 hours at 32°C air / 21°C water. A factory-installed ultrasonic bin control can be adjusted on site. The ice-making head requires a compatible storage bin or dispenser, sold separately.

Removable air filters and snap-fit components provide access for routine cleaning. Maintain the required clearances so the condenser can move air freely.

Bin selection and installation

Select a compatible bin or dispenser and the required top kit for the exact ice-machine model. Cabinet width alone does not establish compatibility. The bin or dispenser is a separate purchase; include its capacity, finished height, door access and utility needs in the installation plan.

Have qualified personnel install the head on a level, securely supported bin or dispenser, indoors and away from heat-producing equipment. Leave at least 15 cm at the rear, sides and top for ventilation and service. Keep the bin opening and ice-drop path clear, and follow the mounting and sealing instructions for the complete assembly. Ice output depends on incoming-water temperature, ambient conditions and installation.

Electrical connection

This 50 Hz model requires an independent, properly earthed 220–240V supply and a matching outlet for its Type G fused plug. The factory cord is 3,000 mm long. Do not remove the earth connection, use an adapter or extension cord, or connect it to a 115V / 60Hz supply. Complete all connections in accordance with local requirements and the model’s instruction manual.

Water supply and drainage

Connect potable water to the ½-inch FPT ice-making inlet and provide a ¾-inch FPT ice-maker drain. Have the installer size the supply and drain lines using the exact model’s installation documents and local requirements. Provide shut-off and drain valves and enough access for service.

Route the ice-maker drain and the separate bin or dispenser drain independently. Use a vented tee and at least ¼ inch of fall per horizontal foot, with a minimum 2-inch vertical air gap above the floor drain. The condensation drain may join the ice-maker drain or run separately. Select external water treatment for local water quality with a qualified installer; do not run the machine without the required water supply.

Cleaning and maintenance

Clean and rinse the ice scoop daily, and wipe the exterior monthly with a soft cloth and neutral cleaner. Inspect air filters every two weeks and wash them when dirty. Clean and sanitize the ice maker and the separate bin or dispenser at least yearly, with more frequent service when water quality, operating conditions or sanitation rules require it. Have the condenser and water-inlet screen inspected and cleaned on the maintenance schedule.

Follow the complete cleaning and sanitizing sequence, including power isolation and rinse cycles. Do not use ammonia cleaners, leave cleaning solution on ice-contact parts or serve ice made with cleaning or sanitizing solution. Wear the protective equipment specified for the chemicals. For extended non-use or freezing conditions, follow the shutdown and drainage procedure for the head and its related equipment.

Warranty

Contact Hoshizaki for warranty terms applicable to this 50 Hz model and its installation country. Confirm coverage before purchase; coverage for a 115V / 60Hz model should not be assumed to apply.
