Drain Connections -Follow all applicable codes.
As ice melts in the dispenser, the water must be drained away. It is critical that a proper drain be
connected to the dispenser. Remember that this is a gravity drain system, the drain tubing must
slope down a minimum of ¼ inch per foot of horizontal run. Usually an air gap must be established
between the end of the drain tube and the building’s drain receptacle. The dispenser’s vented
drain must be separate from the drain used by the ice machine.
Electrical Connections - Follow all applicable codes.
There is a junction box on the back of the dispenser, connect the power supply to the wires inside
the junction box. Be certain that the ice machine and dispenser are grounded.

Sanitation / Maintenance
CD300
Schedule
An ice system represents a sizable investment of time and money in any company’s business. In
order to receive the best return on that investment, periodic maintenance is required. It is the user
responsibility to see that the machine is properly maintained. Maintenance and cleaning should be
done a minimum of twice per year, and more if the ice machine is operating is a dusty area.
Monthly:
Unlock the sink and remove it. Then pull out the removable upper drain chute. Clean out any
debris that may have accumulated in it.
Check the lower drain pan for debris, remove any and pour one quart of an approved sanitizing
solution into the drain pan. Flush with warm water.
Return the upper drain pan and sink to their original positions.
Ice Machine: Follow the instructions in the ice machine service manual.
Dispenser: The only maintenance required is the periodic cleaning of the drain pans, screens and
sanitizing the bin.
Sanitizing
1. Vend all ice out of the dispenser
2. Remove the ice machine front panel and switch it to OFF.

9. Mix a cleaning solution of 8 ounces of approved ice machine cleaner and 3 quarts of warm
(95ºF-115ºF) potable water.
10. Scrub the interior of the dispenser’s hopper and rotor with the cleaning solution.
11. Scrub the metal parts removed in step 7 with the cleaning solution.
12. Scrub the inside of the ice with a clean cloth and the cleaning solution.
13. Mix two gallons of approved sanitizing solution; one possible solution is 1 ounce of household
bleach to 2 gallons of warm (95ºF-115ºF) potable water.
14. Thoroughly wash the inside of the dispenser’s hopper, including the shaft and all side of the
rotor with the sanitizing solution.
15. Thoroughly wash the inside of the ice chute with the sanitizing solution.
16. Thoroughly wash the metal parts and the nut removed in step 6 with the sanitizing solution.
17. Reassemble rotor to shaft, return metal parts to rotor and secure with nut.
