This document serves as an instruction manual for the Hoshizaki Modular Crescent Cuber, specifically covering models KMD-201AB, KMD-201AWB, KMD-270AB, and KMD-270AWB. It provides essential information for the proper installation, safe use, and maintenance of the commercial icemaker.

Function Description

The Hoshizaki Modular Crescent Cuber is a commercial icemaker designed to produce edible crescent-shaped ice. It operates automatically once properly installed and commissioned. The unit is available in both air-cooled (AB models) and water-cooled (AWB models) configurations, catering to different environmental and operational needs. The core function involves a controlled freezing process to form ice, which is then harvested and stored in an accompanying storage bin or dispensed. The icemaker includes a bin control system to manage ice production based on the fill level of the storage bin, ensuring a continuous supply without overfilling.

Usage Features

Installation: The installation process is critical for the safe and efficient operation of the icemaker. Upon unpacking, it's important to remove all shipping materials and protective films. The unit must be placed on a firm, level foundation and positioned to allow adequate air circulation, with specific clearance requirements for the rear, left, top, and right sides. The appliance is not suitable for outdoor use and has specific ambient and water temperature ranges for optimal performance. Electrical connections must adhere to local codes and regulations, requiring a dedicated 240VAC supply protected by a circuit breaker and Residual Current Device. The icemaker must be earthed to prevent electrical shock. Water supply connections require potable water and must comply with plumbing codes, including the installation of a dual check valve for backflow prevention. Drain lines should be gravity-fed into an open trap, maintaining a vertical air gap to prevent backflow into the storage bin.

Operation: Once installed, the icemaker is designed for automatic operation. Users must ensure the water supply tap is on, the unit is plugged into the power supply, and the control switch is in the "ICE" position. The icemaker will then begin the automatic icemaking process. It is crucial to note that the unit will not work at subfreezing temperatures, and the water supply line should be drained if air temperature drops below zero to prevent damage. If the unit is turned off, a waiting period of at least 3 minutes is required before restarting to prevent damage to the compressor. The storage bin is exclusively for ice; no other items should be stored inside. When removing ice, users should wash their hands and use the provided plastic scoop to maintain hygiene. The door should be kept closed to prevent dirt, dust, or insects from entering.

Long Storage Preparation: For periods of long storage, the icemaker needs to be properly prepared. This involves moving the control switch to the "OFF" position, unplugging the unit or disconnecting the power supply, and closing the water supply tap before removing the inlet hose. All ice should be removed from the storage bin/dispenser, and both should be cleaned. Professional qualified personnel should be consulted for draining the icemaker.

Maintenance Features

Cleaning: Regular cleaning is essential for hygiene and optimal performance. Before any cleaning or maintenance, the icemaker must be unplugged from the electrical supply.

Machine and Bin Exterior: The exterior should be wiped at least once a week with a clean, soft, damp cloth and a neutral cleaner to remove grease or dirt.
Scoop: The ice scoop should be cleaned by soaking it in a solution of water and sodium hypochlorite (or recommended Hoshizaki sanitiser) for over 3 minutes, then thoroughly rinsed and air-dried. Using a cloth to dry it may lead to re-contamination.
Storage Bin Interior (Weekly): The storage bin door should be opened, and all ice removed. The bin liner and door inner surface should be washed with a neutral non-abrasive cleaner, rinsed thoroughly, and then wiped with a solution of water and sodium hypochlorite (or recommended Hoshizaki sanitiser). After wiping, it should be thoroughly rinsed with fresh water and a clean cloth. Care must be taken to rinse sanitiser unless otherwise directed by Hoshizaki guidelines, as some solutions can damage bin liner surfaces or cause corrosion.
Air Filter (Bi-monthly): The plastic mesh air filters remove dirt and dust, preventing the condenser from clogging. They should be removed and cleaned at least twice a month. Cleaning can be done with a vacuum cleaner; for severely clogged filters, warm water and a neutral cleaner can be used. After washing, the filter must be thoroughly rinsed and dried before being placed back in position. Users should not put their hand inside the machine compartment.
Icemaking Water System: Periodic cleaning of the icemaking water system is recommended to maintain hygiene. This task should be performed by a trained service person at least twice a year. The washing switch on the control box is for service personnel use only and should remain in the "ICE" position during normal operation.

Troubleshooting (Before Calling Service): If the icemaker is not working properly, users should check a few basic things before calling for service:

Ensure power is supplied to the unit.
Verify the control switch is in the "ICE" position.
Confirm the water supply is turned on.
Check that the air filter is clean. If these checks do not resolve the issue, the manual provides a table of alarm codes (number of beeps) and their corresponding problem types (e.g., High Evaporator Temp., Harvest Backup Timer, Freeze Timer, Low/High Voltage) along with reset instructions. For further assistance, the local Hoshizaki service agent should be contacted.

Warranty: Hoshizaki provides a two-year warranty from the date of installation, covering defects in material and/or workmanship. This warranty excludes routine servicing, cleaning, essential maintenance, and repairs due to misuse or installations not conforming to Hoshizaki guidelines. Warranty repairs must be completed by an approved Hoshizaki dealer or service agency using genuine Hoshizaki components. Full warranty details can be obtained from the dealer/supplier or the nearest Hoshizaki Service office.

Disposal: When disposing of the appliance, local regulations for appliance and refrigerant gas disposal must be followed. The door should be removed to prevent children from being trapped. The product contains a hermetically sealed refrigeration system with fluorinated greenhouse gases and uses flammable gas cyclopentane as an insulation foaming agent. It should be recycled responsibly to promote sustainable reuse of materials and prevent harm to the environment or human health.
