GENERAL INSTRUCTIONS
UNIT SPECIFICATIONS
The IDC175-HD tower is a high capacity ice drink dispenser with two different drink dispensing sides. One side is for
the drive through and the other one is for the store. Both sides are crew operated. The IDC 175-HD tower dispenser
has 8 SFV1/LVV portion control valves and a Progate ice chute on each side. The machine has built-in cup and lid
dispensers for easy usage.
START-UP AND OPERATING INSTRUCTIONS
IDC175-HD Tower Ice Drink Dispenser
The IDC175-HD Tower ice drink dispenser shall be installed by qualified personnel following instruction given in the
Installation manual part number 621058513INS. Start up the beverage system and adjust faucets to the proper BRIX.
Contact your local syrup distributor for complete information on the beverage system.
The ice drink dispenser is designed to operate in ambient temperatures ranging from 65 to 95° F (18 to 35°C). Do not
allow the unit to be stored or operated in conditions below 32° F (0° C). This could cause damage to the unit.
CAUTION:
!
Dispenser cannot be used with crushed or flaked ice. Use of bagged ice which has frozen into large chunks can
void warranty. The dispenser agitator is not designed to be an ice crusher. Use of large chunks of ice which “jam
up” inside the hopper will cause failure of the agitator motor and damage to the hopper. If bagged ice is used, it
must be carefully and completely broken into small, cube-sized pieces and left to “temper” or warm up for a
minimum of 20 minutes at room temperature before loading into the dispenser hopper
In normal operation, pushing the ice dispenser mechanism will cause ice to flow from the ice chute. Ice flow will
continue until the dispenser mechanism is released. Dispensing of any faucet will provide beverage of the appropriate
flavor.
!
WARNING:
Use caution to avoid spilling ice when filling dispenser. Clean up immediately any spilled ice from filling or operating
the unit. To prevent contamination of ice, the lid must be installed on the unit at all times.Failure to clean up
spills could result in serious injury or death

MONTHLY CLEANING: (INADDITION TO DAILY CLEANING PROCEDURES)
Product Tubing cleaning:
IMPORTANT: Only trained and qualified persons should perform these cleaning and sanitizing
procedures.
Sanitize Pre-Mix And Post–Mix Tank System
1. Remove all of the quick disconnects from all of the tanks. Fill a suitable pail or bucket with the soap
solution.
2. Submerge all of the disconnects (gas and liquid) in the soap solution, and then clean them using a nylon
bristle brush (Do not use a wire brush). Rinse with clean water.
3. Prepare the sanitizing solution, and spray the disconnects using a mechanical spray bottle. Allow to air dry.
4. Using a clean, empty tank, prepare five (5) gallons of the sanitizing solution. Rinse the tank disconnects
with approximately 9 oz. of the sanitizing solution. Close the tank.
5. Prepare the cleaning tank by filling the clean five (5) gallon tank with a mixture of mild detergent and
potable water (120°F/49°C).
6. Connect a gas disconnect to the tank, and apply one of the product tubes to the cleaning tank. Operate the
appropriate valve until the liquid dispensed is free of any syrup.
7. Disconnect the cleaning tank and hook up the sanitizing tank to the syrup line and CO2 system.
8. Energize the beverage faucet until the sanitizing solution is dispensed through the faucet. Flush at least
two (2) cups of the liquid to ensure that the sanitizing solution has filled the entire length of the syrup
tubing.
9. Allow the sanitizer to remain in the line for fifteen (15) minutes.
10. Repeat the step above, applying a different product tube each time until all the tubes are filled with the
sanitizing solution.
