A minimum of 1/4" nominal ID copper water tubing or equivalent is required for the condenser water supply line. • A condenser water supply line shut-off valve and drain valve should be installed. • Condenser drain outlet is 3/8" FPT. A minimum of 1/4" nominal ID hard pipe or equivalent is required for the condenser drain line.
b) Connection to a Closed Loop System • Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of 1/4" nominal ID copper water tubing or equivalent is required for the condenser water supply line. • Condenser return outlet is 3/8" FPT. A minimum of 1/4" nominal ID copper water tubing or equivalent is required for the condenser return line. • Shut-off valves and drain valves should be installed at both the condenser water supply inlet and condenser return outlet.
G. 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 ice storage bin.
H. Startup WARNING • All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. • If the icemaker is turned off, wait for at least 3 minutes before restarting the icemaker to prevent damage to the compressor. • At startup, confirm that all internal and external connections are free of leaks. 1) Open the water supply line shut-off valve(s). 2) Move the control switch to the "OFF" position. See Fig. 7.
10) Confirm bin control operation: Remove the control box cover and ice storage bin cover, move the control switch to the "ICE" position, then engage the safety switch on the front frame. See Fig. 7. After the "GM" LED on the control board turns on (5 sec.), the 5-min. ice purge timer starts. Bypass the 5-min. ice purge timer by pressing the "SERVICE" button on the control board. See Fig. 8. WARNING! Risk of electric shock. Care should be taken not to touch live terminals. Otherwise, wait for the 5-min.
I. Dispense Mode Switch The dispense mode switch has "CONTINUOUS" and "PORTION" positions. When the dispense mode switch is in the "CONTINUOUS" position, ice dispenses continuously for a maximum of 60 seconds per activation. When the dispense mode switch is in the "PORTION" position, ice dispenses for the amount of time determined by the ice dispense time setting. The ice dispense time control is located on the control board. The dial indicates dispense time in seconds and is adjustable between 0.
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 power switch or control switch with damp hands. • Before Servicing: Move the power switch to the "OFF" position. Turn off the power supply.
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 Bi-Weekly Monthly Air Filters Inspect. Wash with warm water and neutral cleaner if dirty. External Water Check for proper pressure and change if necessary. Filters Icemaker Exterior Wipe down with a clean, soft cloth.
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.
7) Replace spout A, spout B, and the ice storage bin cover in their correct positions. 8) Allow the icemaker to sit for 10 minutes before operation. If you placed a clamp on the reservoir hose in step 6, remove it before operation. 9) In bad or severe water conditions, clean the float switch assembly as described below. Otherwise, continue to step 10. a. Remove the float switch assembly from the reservoir cover. b. Wipe down the float switch assembly with the cleaning solution. c.
c) Sanitizing Solution Dilute 0.82 fl. oz. (25 ml) of a 5.25% sodium hypochlorite solution (chlorine bleach) with 1.6 gal. (6.0 l) of warm water. This is a minimum amount. Make more solution if necessary. IMPORTANT! For safety and maximum effectiveness, use the solution immediately after dilution. d) Sanitizing Procedure - Following Cleaning Procedure 1) Make sure the control switch is in the "OFF" position, the power supply is off, and the icemaker water supply line shut‑off valve is closed.
3) Remove the ice storage bin cover. 4) Remove the motor bracket thumbscrews, first from the vertical plane and then from the horizontal plane. While holding on to the corresponding agitator or auger, move the agitating motor or the dispensing motor towards you. Remove the agitator(s) and the dispensing auger from the ice storage bin. See Fig. 9. Note: DCM-300 and DCM-500 models have 1 agitator and DCM-751 and DCM-752 models have 2 agitators. 5) Remove the bin control assembly. See Fig. 10.
IV. Preparing the Appliance for Periods of Non-Use NOTICE When storing the appliance for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage. When the appliance is not used for two or three days under normal conditions, it is sufficient to move the power switch to the "OFF" position. When storing the appliance for an extended time or in sub-freezing temperatures, follow the instructions below. 1.
2. On water-cooled model only, remove the water from the water-cooled condenser: 1) Make sure the control switch and the power switch are in the "OFF" position and that the power supply is off. Remove the top, apron, and left 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.
