Icemaking Water System - Hoshizaki IM-21 Service Manual

4. ICEMAKING WATER SYSTEM

To keep the icemaker hygienic, clean and sanitize the icemaking water system at least once
every six months. More frequent cleaning and sanitizing may be required depending on the
water quality.
1. Do not touch the Washing Switch with damp hands.
2. Always wear rubber gloves, eye protectors, apron, etc. for safe handling of
the cleaner and sanitizer.
3. Use the cleaners and sanitizers recommended by Hoshizaki. Contact your
local Hoshizaki office for further details. (The instructions below give an
example of those recommended cleaners and sanitizers.)
4. Never mix cleaning and sanitizing solutions in an attempt to shorten cleaning
time.
5. Wipe off any splashed or spilt cleaner/sanitizer immediately.
6. Do not use any ammonia type cleaners on any part of the icemaker.
7. When the ambient and water temperatures are 10°C or below, the Water Pan
may remain open. Warm the icemaking compartment up to 20°C around the
Thermistor.
8. Be sure to follow the cleaning and sanitizing instructions below.
1) Use a suitable container to dilute the cleaner ("Nickel-Safe Ice Machine Cleaner" by The
Rectorseal Corporation) into the following concentration:
IM-21 - 65
Mix 79 ml of the cleaner with 3.8 litres of water.
IM-100/130/160
Mix 157 ml of the cleaner with 7.6 litres of water.
IM-240
Mix 236 ml of the cleaner with 11.4 litres of water.
2) Open the Storage Bin Door, and remove all the ice to avoid contaminating by the cleaner.
3) Remove the Front and Top Panels.
4) If the icemaker is in a defrost cycle, wait until a freeze cycle starts.
5) Remove the screw, and move the Tank Drain Pipe to the drain position. See Fig. 10. (IM-
