CLEANING INSTRUCTIONS OF WATER SYSTEM
1. Switch OFF the power supply to the MDT2.
2. Remove the top panel and the top cover of the
storage bin with the dispensing drive motor.
3. Remove all ice stored in the bin to prevent it
from getting contaminated with the cleaning
solution.
4. Close the water shutoff valve on water line.
5. Remove the left side panel to gain access to the
water reservoir.
6. Remove the float reservoir cover and jump the
two water level sensors with a piece of copper
wire.
7. Remove the right service panel and loosen the
drain plug from the water purge tube to drain all of
water our of the freezer. Then re-plug the purge
tube.
CLEANING
8. Prepare the cleaning solution by diluting it in a
plastic container with 2.1 quarts (2 liters) of warm
water (113°-122°F) with 7 ounces (0.2 liters) of
SCOTSMAN Ice Machine Cleaner.
WARNING: SCOTSMAN Ice Machine Cleaner
contains Phosphoric and Hydroxyacetic acids.
These compounds are corrosive and may cause
burns if swallowed, DO NOT induce vomiting. Give
large amounts of water or milk and call a Physician
immediately. In case of external contact, flush with
water. KEEP OUT OF THE REACH OF CHILDREN
9. Pour the cleaning solution into the water
reservoir until it reaches the proper level.
10. After 15 minutes switch ON the Master switch
to start the unit.
11. Wait till the machine starts to discharge ice,
then continue to slowly pour the cleaning solution
into the water reservoir taking care to maintain the
level just below the overflow.
NOTE: The ice made with the cleaning solution is
slushy and colored. It may also loose fluidity
creating some resistance in being elevated and
extruded; this situation can be heard by the
creaking noise made by the ice.
If this should occur it is recommended that you
stop the ice machine for few minutes in order to
allow the ice in the freezer to partially melt.
12. When all of the cleaning solution has been
used up, open the water shutoff valve to allow new
fresh water to flow into the reservoir. Let the unit
continue to run until the ice resumes the normal
color and hardness.
13. Stop the ice machine and pour warm water on
the ice deposited into the storage bin to melt it.
NOTE: DO NOT use ice produced with the
cleaning solution. Be sure none remains in the bin.
SANITATION
14. Pour into the water reservoir locally approved
sanitizer mixed according to the directions for that
sanitizer. A possible saniziter can be obtained by
mixing 1 ounce of liquid household bleach with 2
gallons of warm water.
15. Leave the unit running for approx 10 minutes
then remove the copper wire used to jump the two
sensors for the water level and place the cover
back on the float reservoir.
NOTE: DO NOT use ice produced with the
sanitizing solution.
16. With a sponge moistened with a sanitizing
solution, wipe clean all bin interior surfaces.
REMEMBER: To prevent the accumulation of
undesirable bacteria it is necessary to sanitize the
interior of the storage bin with an anti-algae
disinfectant solution every week.
