  • Page 36: Bin Control Check

    D. Bin Control Check 1. Thermostatic Bin Control Check BC shuts down the icemaker within 10 sec. when ice contacts the thermostatic bulb, regardless of the cycle at activation. NOTICE When the ambient temperature is below 45°F (7°C), BC opens and shuts down the appliance even if the ice storage bin is empty.

  • Page 37: Mechanical Bin Control Check

    2. Mechanical Bin Control Check a) Mechanical Bin Control Check This appliance uses a lever-actuated proximity switch to control the ice level in the storage bin. No adjustment is required. To check MBC, follow the steps below. 1) Turn off the power supply. 2) Remove the front panel, then move the control switch to the "OFF"...
  • Page 38 5) Remove the actuator paddle from the switch mount. See Fig. 2. 6) Wipe down MBC with a mixture of 1 part of Hoshizaki "Scale Away" and 25 parts of warm water. Rinse the parts thoroughly with clean water.

  • Page 39: Float Switch Check And Cleaning

    E. Float Switch Check and Cleaning FS is used to determine that there is sufficient water in the water tank after the 1-min. fill cycle and after each harvest cycle. FS is also used to determine that the appropriate volume of water has been converted into ice before switching out of the freeze cycle. No adjustment is required.

  • Page 40: Float Switch Cleaning

    Be careful not to bend the retainer rod excessively when removing it. 7) Wipe down FS housing, shaft, float, and retainer rod with a mixture of 1 part Hoshizaki "Scale Away" and 25 parts warm water. Clean the inside of the rubber boot and hose with cleaning solution.

    3. Pump-Out Timer (S4 dip switch 3 & 4) NOTICE On models with harvest pump timer, do not adjust 3 off and 4 on. Pump does not run in pump-out rotation in this setting. When a pump-out is called for, the pump motor stops for 2 sec., then energizes in the reverse direction, taking water from the bottom of the water tank and forcing pressure against the check valve seat allowing water to go through the check valve and down the drain.

  • Page 54: Pump-Out Frequency Control (S4 Dip Switch 5 & 6)

    4. Pump-Out Frequency Control (S4 dip switch 5 & 6) The pump-out frequency control is factory set. Generally no adjustment is required. However, where water quality is bad and the icemaker needs a pump-out more often, the pump-out frequency can be adjusted. The pump-out frequency control can be set to have a pump-out occur every cycle, or every 2, 5, or 10 cycles.

  • Page 55: B) Harvest Pump Timer: "G" Control Board

    In this case, see "II.G.3. Low Ice Production" for possible solutions. The freeze timer is factory set and no adjustment is required. Before changing this setting, contact Hoshizaki Technical Support at 1-800-233-1940 for recommendations.

  • Page 58 2. Brazing WARNING • R-404A itself is not flammable at atmospheric pressure and temperatures up to 176°F (80°C). • R-404A itself is not explosive or poisonous. However, when exposed to high temperatures (open flames), R-404A can be decomposed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous.
  • Page 59 Remember to loosen the connection and purge the air from the hose. For the required refrigerant charge, see the rating label inside the icemaker. Hoshizaki recommends only virgin refrigerant or reclaimed refrigerant which meets ARI Standard 700 (latest edition) be used.

  • Page 60: Component Service Information

    • The thermistor should be at the 12 o'clock position on the tube. • Smoothly fill the recessed area of the thermistor holder with high thermal conductive type sealant. Hoshizaki America part number 4A0683-01 (Silicone Heat Sink Compound 10-8108 manufactured by GC Electronics), KE-4560 RTV (manufactured by ShinEtsu Silicones), or equivalent are recommended.
