Scotsman DCE33 Series User manual

What shouldn’t be done?
Never keep anything in the ice storage bin that is
not ice; objects like wine or beer bottles are not
only unsanitary, but the labels may slip off and plug
up the drain.
Never allow the machine to operate without regular
cleaning. The machine will last longer if it is kept
clean. Regular cleaning should happen at least
once per year, and preferably twice. Some water
conditions will dictate even more frequent cleaning
of the ice making section, and some carpets or
pets will dictate more frequent cleaning of the
condenser.
What should be kept clean?
There are 5 things to keep clean:
1. The outside cabinet & door.
2. The ice storage bin.
3. The condenser.
4. The ice making system.
5. The ice scoop.
How to clean the cabinet.
Wipe off any spills on the surface of the door and
handle as they occur. If anything spilled on the
door or gasket dries onto the surface, wash with
soap and warm water to remove.
How to clean the ice storage bin.
The ice storage bin should be sanitized
occasionally. It is usually convenient to sanitize the
bin after the ice making system has been cleaned,
and the storage bin is empty.
A sanitizing solution can be made of 1 ounce of
household bleach and two gallons of hot (950F. -
1150F.) water. Use a clean cloth and wipe the
interior of the ice storage bin with the sanitizing
solution, pour some of the solution down the drain.
Allow to air dry.
How to clean the condenser.
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged. To clean:
1. Remove the kickplate.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
4. Replace the kickplate.
Winterizing
1. Clean the machine as explained on the next
page.
2. Turn off the water supply.
3. Drain the water reservoir. See page 24, Spray
Pump Repair and follow the instructions to remove
the pump hose (step 2, bottom hose only).
4. Disconnect the incoming water line at the inlet
water valve.
5. Remove control box cover and turn the timer
into the harvest cycle.
6. With the machine operating, blow air through the
inlet water valve; a tire pump could do the job.
7. Drain pump models should have about 12gallon
of RV antifreeze (propylene glycol) poured into the
ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
8. Replace control box cover. Switch off and
unplug the machine.

CLEANING
How to clean the ice making system.
1. Open the door and
turn the ice machine
control knob to off.
2. Scoop out all of the ice, either discard it or save
it in a ice chest or cooler.
3. Pour 4 ounces of Scotsman Clear 1 Ice Machine
Cleaner (available from a local Scotsman
Distributor or Dealer), into the ice machine
reservoir.
4. Turn the ice machine control to ON.
5. Allow the machine to operate for about 2 hours.
6. Pour hot (950F. - 1150 F.) water into the bin to
melt the ice that has formed. That ice will likely be
white and frosty looking.
7. Clean the bin liner of mineral scale by mixing
some ice machine cleaner and hot water, and
using that solution to scrub the scale off of the
liner.
8. Rinse the liner with hot water.
9. Sanitize the bin interior.
10. Replace the ice removed in step 2.
The ice scoop should be washed regularly, wash it
just like any other food container.
Note: Over time biofilm can grow inside the drain
system which can affect the ability for the drain
system to evacuate the drain water. On the pump
models this can also drive a erratic pump
operation. Including the pump cycling rapidly or
running all the time. Biofilm and pump cycling
issues will eventually lead to low production and
standing water in the bin. To ensure that this does
not become an issue frequent bin sanitizing may
be required.
