Scotsman HID Service manual

HID Ice Maker-Dispenser PM
Planned Maintenance:
Ice Machines require periodic maintenance to be able to deliver like-new reliable performance. That
maintenance will be in ve areas:
• Drip tray and drain system
• Air cooled condenser lter and condenser
• Ice dispense bin and rotor
• Photo eye ice level control
• Ice making water system
The maintenance includes:
• Scale removal
• Sanitization
• Filter cleaning or change
Schedule:
Typically twice per year for scale removal and sanitizing. At some sites the water supply to the ice machine
will contain signicant quantities of minerals, and that will result in a water system becoming coated with these
minerals, requiring more frequent maintenance than twice per year.
Drip Tray and Drain:
• Weekly ush out recommended
Air Filter Cleaning:
• Monthly and every 6 months with the ice machine scale removal
Ice Dispense Bin and Rotor Cleaning and Sanitizing:
• At the same time of scale removal and ice machine sanitization, more frequently if needed
Photo Eye Ice Level Control
• At the same time of scale removal
Ice Machine Water System, including water lters:
• Remove scale from water system and change lters a minimum of every 6 months
• Sanitize the water system whenever the scale has been removed
For the Owner or Operator - several items can be “do it yourself” procedures:
• Water lter change - estimated time 5 minutes
• Air lter cleaning or change - estimated time 10 minutes

Ice Dispense Bin and Rotor Cleaning and Sanitizing
Necessary Materials
Hand tools, cleaning supplies including scale remover and sanitizer, plus hand protection are recommended.
Frequency and Background:
Recommended minimum time between cleanings is 6 months. To aid in determining if the machine has not
been cleaned in 6 months, a Time To Clean light will glow after 6 months of power up time. Cleaning the
machine with the following process will reset that light and the timer that controls it. More frequent cleanings
may be required based on the mineral content of the water, run time and potential airborne contamination.
Basic Process - See User Manual for Complete Details
1. Remove both front panels.
2. Push On/Off button to shut ice making off.
3. Shut water supply off, either by lifting the oat
with the lever on the size of the reservoir or by

reservoir drain hose from plug at drain basin
and return to plug when drained.
Note: Drain into drain basin in base of unit. Sink
must be attached to unit throughout this process.

5. Remove reservoir cover and ll with hot (110-
120 degree F.) water, wait 2 minutes and
drain water from ice making system by pulling
reservoir drain hose from plug and return
hose to plug when drained.
6. Mix a solution of 12 ounces of Scotsman
Clear 1 ice machine scale remover and 12
ounces of clean, potable water.
7. Loosen thumb screw holding water reservoir
to post.

18. Drain the water from the water system by
pulling the reservoir drain hose from its plug
and return it to the plug when drained.
19. Mix a solution of 4 ounces of ice machine
scale remover and 16 ounces of potable
water. Use this scale remover solution
to washout the water reservoir cover, ice
discharge chute, ice chute cover, ice delivery
chute, storage bin cover and inside of the ice
storage bin. Also wash the sink /drip tray and
grill with this solution. Pour half down the bin
drain and the rest into the sink / drip tray to
ush out their drains.

Sanitize now.
20. Mix a 2 gallon solution of sanitizer. A
recommended sanitizer solution is one 2 oz.
packet of Stera Sheen Green Label and 2

or an equivalent sanitizer at a concentration of
100 ppm.
21. Pour the sanitizer solution into the reservoir
until it is full (level with the molded line on the
side).
22.Reconnect electrical power.
23.Push the On/Off button to make ice for 10
minutes. Add more sanitizer to the reservoir to
keep it full while making ice.
24.Push the On/off button to stop making ice.

25. Disconnect electrical power.
26.Remove the ice outlet cover, dispense rotor
and ice dispenser agitator from the bin. Wash
them with the sanitizer solution.
27.Wash all inside surfaces of the ice storage
bin and ice discharge chute with the sanitizer
solution.

28.Wash the ice discharge chute cover, ice
sweep, metal area below the ice sweep and
ice dispense chute with the sanitizer solution.
29.Wash the sink / drip tray and grill with the
sanitizer solution. Pour remaining sanitizer
into the bin and sink. Do not overll bin.
30. Drain sanitizer from ice making system by
pulling reservoir drain hose from plug and
return hose to plug when drained. Repeat with
clean water.

31. Loosen thumb screw holding water reservoir
to post and lower the water reservoir to the
