VI. Cleaning and Maintenance Instructions  
IMPORTANT  
Ensure all components, fasteners and thumbscrews are securely in place after  
any maintenance or cleaning is done to the equipment.  
A. Preparing the Ice Dispensing Bin for Long Storage  
IMPORTANT  
Drain the icemaker and remove all ice from the ice dispensing bin when  
shutting off the icemaker/ice dispensing bin for storage. The ice dispensing bin  
should be cleaned and wiped dry.  
1) Shut off the icemaker. See the "Preparing the Icemaker for Long Storage" instructions on  
the icemaker.  
2) Turn off the power supply switches for both the icemaker and the ice dispensing bin after  
removing all ice.  
3) Clean the ice dispensing bin and wipe it dry.  
B. Cleaning Instructions  
WARNING  
1. HOSHIZAKI recommends cleaning this unit at least once a year. (See the  
"Cleaning Instructions" on the icemaker.) More frequent cleaning, however,  
may be required in some existing water conditions.  
2. To prevent injury to individuals and damage to the icemaker/ice dispensing  
bin, do not use ammonia type cleaners.  
3. Always wear liquid-proof gloves to prevent the cleaning and sanitizing  
solutions from coming into contact with skin.  
1. Cleaning Procedure  
1) Clean and sanitize the ice dispensing bin/icemaker (see the cleaning instructions on the  
icemaker) as conditions require.  
2) Remove all ice from the bin.  
3) Disconnect electrical power to the ice dispensing bin/icemaker.  
4) Remove the drain gate and simply lift out the chute for cleaning.  
5) Remove or reposition the icemaker to allow access to the inside. Be sure that the  
icemaker is secured and cannot fall.

6) Scrub the inside of the bin, the agitator, the spout of the bin, the spout of the front panel  
and chute using a nylon scouring pad, brushes and cleaning solution, such as 5 oz.  
Hoshizaki “Scale Away” or “Lime-A-Way” (Economics Laboratories Inc.), in one gallon of  
water.  
7) Remove the shutter assembly and spout and scrub them using the cleaning solution  
made in step 6. See the illustration on the previous page.  
a) Remove the snap pin fitted to the shutter shaft and shift the shaft to  
the right. Then the shutter assembly can be removed from the bin.  
b) Pull out on the sides of the hook to release the spout. Lift the spout up and out from  
the bin.  
c) Remove the thumbscrews holding the hook and take it off the spout. Take off the  
snap pin and the axle from Shutter (B). Open out Shutter (B) and remove the balance  
weight.  
8) Rinse all parts thoroughly with clean water.  
2. Sanitizing Procedure – Following Cleaning Procedure  
1) Wash all parts in steps 6) and 7) using the following sanitizing solution: 1/2 fl. oz. of a  
5.25% sodium hypochlorite solution (chlorine bleach) diluted in 1 gallon of water.  
2) Rinse all parts thoroughly with clean water.  
3) Reassemble in the reverse order of the removal procedure.  
4) Turn on the icemaker/ice dispensing bin.  
5) Check for proper operation.  
C. Maintenance  
1) Exterior Panels  
To prevent corrosion, wipe occasionally with a clean, soft cloth. Use a damp cloth  
containing a neutral cleaner to wipe off oil or dirt build up.  
2) In view of the simple design of this ice dispensing bin, and the limited operating time,  
very little maintenance is required.  
Inspect and oil the chain (2 or 3 drops) annually. Adjust as necessary for 3/8” to 1/2” free  
play.
