  1. This icemaker is not intended for outdoor use. Normal operating ambient temperature should be within 7°C to 43°C. Normal operating water temperature should be within 7°C to 35°C. Operation of the icemaker, for extended periods, outside of these normal temperature ranges may affect production capacity.
  2. The ice maker should not be located next to ovens, grills, or other high heat-producing equipment.
  3. The location should provide a firm and level foundation for the equipment.
  4. Allow at least 5 cm clearance at the right side for proper air circulation and at least 15 mm clearance at the top for ease of maintenance and/or service should they be required.
  5. This appliance is not suitable for installation in an area where a water jet could be used and where dripping is not allowed.
  6. Do not place anything on the top, front, and right sides of the icemaker. Especially, do not block the air inlet on the right side.
  7. This ice maker will not work at subfreezing temperatures. To prevent damage to the water supply line, drain the icemaker when the air temperature is below zero (see “II. 2. PREPARING THE ICEMAKER FOR LONG STORAGE”).


  • Incorrect installation can cause harm to people, animals, or things, for which the manufacturer cannot be held responsible.
  • Place the icemaker in the selected permanent site.
  • The appliance must be positioned so that the plug is accessible.


This icemaker requires earth that meets the national and local electrical code requirements. To prevent possible severe electrical shock to individuals or extensive damage to equipment, install a proper earth wire to the icemaker. Remove the plug from the mains socket before any maintenance, repairs or cleaning is undertaken.

  • This appliance requires a separate 220 – 240VAC, 10A supply. The electrical supply must be protected by a suitable circuit breaker.
  • The main control box fuse is rated at 5A, 250V, and should only be replaced by a qualified service engineer.
  • Usually, an electrical permit and the services of a licensed electrician are required.

For the U.K. and the Republic of Ireland only

  • The wires in the mains lead are colored in accordance with the following code:
    Green & Yellow = Earth
    Blue = Neutral
    Brown = Live
    As the colors of the wire in the mains lead of this appliance may not correspond with the colored markings identifying the terminals in your plug, proceed as follows:
    The wire which is colored Green-and-Yellow must be connected to the terminal in the plug which is marked with the letter E or by the symbol or colored Green or Green-and-Yellow. The wire which is colored blue must be connected to the terminal which is marked with the letter N or colored Black. The wire which is colored brown must be connected to the terminal which is marked with the letter L or colored Red.
  • Should the socket outlets in the installation site not be suitable for the plug supplied with your product, the plug must be removed (cut off if
    it is molded on the plug) and an appropriate plug fitted. If the non-rewirable plug has been cut from the power supply cord, it must be disposed of. There should be no attempt to reuse it. Inserting such a plug into a socket elsewhere presents a serious risk of electrical shock.
  • The non-rewirable plug must never be used without a fuse cover being fitted.
    The correct replacement for the detachable fuse cover is identifiable from the manufacturer’s reference number stamped on the plug.
    Supply of replacement fuse covers can be obtained from Hoshizaki Parts/Service Centres.
    Fuses should be rated at 10A and approved to BS 1362.


Connect to potable water supply only.

  • The connections to the mains water supply must be made in accordance with the countries’ current requirements of the Water Supply or Water Fittings Regulations.
  • Icemaking water must be potable water. Where scaling can be caused by water quality, installation of an external filter or softener is recommended. Contact your local water treatment professional or Hoshizaki service agent.
  • Water supply pressure should be a minimum of 0.07 MPa (0.7 bar) and a maximum of 0.8 MPa (8 bar). If the pressure exceeds 0.8 MPa (8 bar), use a pressure-reducing valve. Do NOT throttle back the supply tap.
  • Be sure to use the new hose sets supplied with the appliance. Do not reuse any old hose sets.
  • A plumbing permit and the services of a licensed plumber may be required in some areas.
  • Water should drain into an open trap.
  • The icemaker drain is gravity flow, so ensure the drain pipe has an adequate pitch or fall.
  • To prevent backflow into the storage bin, the outlet hose must be laid as shown in Fig. 2.

  1.  Attach the free end of the inlet hose to the stop valve (Fig. 4), noting the washer is correctly positioned. Hand tightens sufficiently to provide leak-free joint. It is a wise precaution to have the stop valve within easy reach.
  2. Wrap P.T.F.E. tape around the hose adapter fitting, and screw the hose adapter into the drain outlet of the icemaker. Hand tightens grey flexible outlet hose (accessory) onto the hose adapter as indicated(Fig. 3). The pipe can be cut to length as necessary to suit the position of the main drain. To prevent water leaks, secure the outlet hose to the drain outlet by using a hose band.

Note: Jointing compounds should be approved and suitable for potable water use.



  1.  This icemaker is designed to produce and store edible ice. To keep the icemaker hygienic:
    * Wash your hands before removing ice. Use the plastic scoop provided (accessory).
    * The storage bin is for ice use only. Do not store anything else in the bin.
    * Clean the storage bin before use (see “III. 1. CLEANING”).
    * Keep the scoop clean. Clean it by using a neutral cleaner and rinse thoroughly.
    * Close the door after removing ice to prevent the entrance of dirt, dust, or insects into the storage bin.
  2. All parts are factory-adjusted. Improper adjustments may result in failure.
  3. If the unit is turned off, wait for at least 3 minutes before restarting the icemaker to prevent damage to the compressor.


The installer will normally commission the icemaker to start the automatic icemaking process. To ensure continuous operation, make sure that:

Scoop and Bin Door Grip Cleaning/Sanitisation (Daily)

  1. Either mix 3 liters of water with 11 ml of 5.25% sodium hypochlorite solution in a suitable container, or the recommended Hoshizaki sanitizer as directed.
  2. Soak the scoop in the solution for more than 3 minutes. Rinse thoroughly, and shake to remove surplus liquid.
    Note: Using a cloth to dry may re-contaminate.
  3. Use a neutral cleaner to wash the bin door grip. Rinse thoroughly.
  4. Soak a clean cloth with the sanitizing solution, and wipe the grip. Use fresh water and a clean cloth to rinse/dry.

Storage Bin Interior Cleaning/Sanitisation (Weekly)

  1. Open the storage bin door, and remove all ice.
  2.  Wash the bin liner with a neutral non-abrasive cleaner. Rinse thoroughly.
  3.  Soak a clean cloth with the neutral cleaner, and wipe the door’s inner surface. Wipe off the cleaner with a clean damp cloth.
  4. Either mix 3 liters of water with 11 ml of 5.25% sodium hypochlorite solution in a suitable container or the recommended Hoshizaki sanitizer as directed.
  5. Soak a clean sponge or cloth with the solution, and wipe the bin liner and bin door.
  6. Rinse thoroughly with fresh water and a clean cloth to wipe off the solution. Close the bin door.

Note: Some solutions may cause damage to the bin liner surfaces or corrosion on the metal parts. Always rinse the sanitizer unless directed otherwise by Hoshizaki guidelines.
Air Filter

Plastic mesh air filters remove dirt or dust from the air and keep the condenser from getting clogged. If the filters get clogged, the icemaker’s performance will be reduced. Remove and clean the air filters at least twice per month:

  1. Tilt the louver forward, and remove the air filter.
  2. Clean the air filter by using a vacuum cleaner. When severely clogged, use warm water and a neutral cleaner to wash the air filter.
  3. Rinse and dry the air filter thoroughly, and place it in position.
