6. Electrical Connection WARNING • Electrical connection must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or damage. • To reduce the risk of electric shock, make all remote condenser unit connections before connecting the icemaker power supply. • THE REMOTE CONDENSER UNIT MUST BE GROUNDED.
3) Install line, neutral, and ground wires from the icemaker fan motor junction box to the remote condenser unit junction box and make connections. Use wire of an appropriate gage and outdoor rating. 4) Replace the junction box covers and the louver panel in their correct positions. 7. Stacking Remote Condenser Unit 1) Install the lower remote condenser unit as described earlier in this section. 2) Place the upper remote condenser unit on top of the lower remote condenser unit. See Fig. 14.
H. Final Checklist WARNING CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after installation. Make sure that none have fallen into the dispenser unit/ice storage bin.
I. Startup WARNING All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. NOTICE • If the appliance is turned off, wait for at least 3 minutes before restarting the appliance to prevent damage to the compressor. • At startup, confirm that all internal and external connections are free of leaks. • On remote models, the appliance must have power for a minimum of 4 hours prior to startup to prevent compressor damage.
J. Bin Control An infrared sensor bin control controls the level of ice in the dispenser unit/ice storage bin. IMPORTANT • Make sure the icemaker has been installed as outlined in this manual and that the water supply is on. • Confirm S1 dip switch 7 is in the "ON" position. This allows the control board to monitor the infrared sensor. 1. Bin Control Check 1) Turn off the power supply. 2) Remove the front panel and control box cover. Move the power switch to the "OFF" position.
7) "GM" LED and "COMP" LED are on. Use an object to cover the infrared sensor lens at the bottom of the icemaker. If the bottom of the icemaker is not accessible in your application, remove the thumbscrew securing the infrared sensor housing, remove the housing from the base, then cover the infrared sensor lens. See Fig. 16. The yellow LED on the infrared sensor turns on. The yellow LED flashes when ice is at the outer limit of its range and turns steady as ice nears.
2. Bin Control Shutdown Delay This is the delay between the infrared sensor detecting ice and the start of the shutdown sequence. The infrared sensor shutdown delay is factory-adjusted to 100 seconds and no adjustment is required for most dispenser unit/ice storage bin applications. a) Standard Ice Storage Bin When installed on a standard ice storage bin, any shutdown delay setting is acceptable. b) Dispenser Unit For typical dispenser unit applications, a 100-second shutdown delay is recommended.
III. Maintenance The appliance must be maintained in accordance with the instruction manual and labels provided. Consult with your local Hoshizaki Certified Service Representative about maintenance service. WARNING • Only qualified service technicians should service the appliance. • To reduce the risk of electric shock, do not touch the icemaker power switch or control switch with damp hands. • Move the power switch to the "OFF" position and turn off the power supply before servicing.
A. Maintenance Schedule The maintenance schedule below is a guideline. More frequent maintenance may be required depending on water quality, the appliance's environment, and local sanitation regulations. Maintenance Schedule Frequency Area Task Daily Scoop Bi-Weekly Monthly Air Filters External Water Filters Icemaker Exterior Clean the ice scoop using a neutral cleaner. Rinse thoroughly after cleaning. Inspect. Wash with warm water and neutral cleaner if dirty.
B. Cleaning and Sanitizing Instructions The icemaker must be cleaned and sanitized at least twice a year. More frequent cleaning and sanitizing may be required in some conditions. WARNING • To prevent injury to individuals and damage to the icemaker, do not use ammonia type cleaners. • Carefully follow any instructions provided with the cleaning and sanitizing solutions.
10) In bad or severe water conditions, clean the float switch as described below. Otherwise, continue to step 11. a. Remove the float switch from the reservoir cover. b. Wipe down the float switch with the cleaning solution. c. Rinse the float switch thoroughly with clean water. d. Replace the float switch in its correct position. 11) Wipe down the infrared sensor lens, (located on the bottom of the icemaker) with the cleaning solution.
4) Remove the chute assembly from the icemaker. 5) Remove the packing at the bottom of the chute. Remove the 3 ties and the chute insulation. 6) Soak the spout, rubber O-ring, nylon ring, packings, chute bracket, and chute in the sanitizing solution for 10 minutes then wipe them down. 7) Rinse the parts thoroughly with clean water. 8) Replace all parts in their correct positions. 9) Move the control switch to the "ICE" position, then move the power switch to the "ON" position.
14) Turn off the power supply, then remove the front panel. Move the control switch to the "ICE" position, then replace the front panel in its correct position. 15) Turn on the power supply to start the automatic icemaking process. Allow the icemaker to run for 30 minutes, then turn off the power supply. 16) Pour warm water into the dispenser unit/ice storage bin and melt any remaining ice. Clean the dispenser unit/ice storage bin liner using a neutral cleaner. Rinse thoroughly after cleaning.
IV. Preparing the Icemaker for Periods of Non-Use NOTICE When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage. When the icemaker is not used for two or three days under normal conditions, it is sufficient to only move the power switch to the "OFF" position. When storing the appliance for extended time or in sub-freezing temperatures, follow the instructions below. 1.
3. On water-cooled models, remove the water from the water-cooled condenser: 1) Make sure the power supply is off, then remove the front, top, and right side panels. 2) Close the condenser water supply line shut-off valve. If connected to a closed loop system, also close the condenser return line shut-off valve. 3) Open the condenser water supply line drain valve. If connected to a closed loop system, also open the condenser return line drain valve.
V. Disposal The appliance contains refrigerant and must be disposed of in accordance with applicable national, state, and local codes and regulations. Refrigerant must be recovered by properly certified service personnel.
