Water Filtration
•Filtration system should consist of pre-filter to removed large
sediment, followed by carbon filters to remove taste and odor.
•DO NOT USE IMF / DESCALER –These filters remove too many
minerals from the water and will prevent carbonation.
•Hardness = ~50-100ppm Total Mineral Solid = ~350ppm

IMF/Descaler –for coffee and cuber
icemakers.
Filtered water supply to IDC Pro

IDC Pro Key Install Points
•The IDC Pro utilizes cold carbonation (internal carbonator) and an external pump deck.
The pump deck needs to be located within 6 feet of the unit and receives power from
the level control board located in the IDC Pro E-box. The power cord will be behind the
splash panel on top of the cold plate.
•The IDC Pro requires a ½” ambient water line regulated to 65 psi before pump deck.
The WPR should be located 12”-18” before the inlet of pump deck.
–65Psi WPR PN: 620055952
•The IDC Pro requires a 3/8” CO2 line supplied at 90-110 psi to pump deck. The pump
deck contains a secondary Co2 regulator that is preset to 75 psi and the outlet of the
regulator must be connected to carbonator tank inlet.
–Note: Use bulk Co2 pressure to supply Co2 to the pump deck
•Note: The secondary Co2 regulator for the flavor shots is not supplied.

IDC Pro Ice Dispense Features
•No ice maker adapter needed, the hopper cover has perforated
cutouts for the most popular ice maker drop zones. Manual fill door
in the front to be used as needed.
–Ice support bars are sent with the IDC Pro and must be used to support
the ice maker. The Hopper lid / ice maker adapter will not support the
ice maker without the ice maker support bars.
•Interlock safety switch on touch screen door and activation magnet
on lid to prevent agitation with door open
•Mechanical ice chute mechanism, with encapsulated magnet on the
upper / outer ice chute and proximity switch / sensor on the unit.
•Two piece motor and gear box, ease of replacement

7
Ice Hopper Lid / Icemaker Adapter
•Identify and measure the drop
zone of the ice maker that will be
mounted on the IDC Pro.
Carefully cut along the
perforated lines to remove the
proper drop zone.
•NOTE: You can cut outside the
lines if needed but be sure to
only cut within the drop zone of
the ice maker to avoid leaving
openings along the sides of the
ice maker. Remember that the
ice hopper is a food zone.
•Manual fill lid if needed

8
Ice Hopper Lid / Icemaker Adapter and
Support Bars
•You will receive 3 ice maker support bars; 1
long and 2 short.
•The long bar will span side to side and will be
placed in the center or front of the hopper
depending on the ice maker.
•The short bars will only be used if the long bar
is used in the front position.

9
Hopper lid magnet
•The hopper lid must be on the
hopper and in the proper orientation
for agitation to take place.
•Agitation will not take place if the
hoper lid is not installed properly.

10
Safety Interlock Switch
•The safety interlock switch is a safety
device that is located on the top
center back of the touch screen. (12
o’clock position)
•This switch prevents agitation when
the touch screen door is open or if
the hopper lid is not in place.
•The activation magnet is attached to
the hopper lid (shown in previous
slide).
•Bypassing the safety interlock switch
is for TROUBLESHOOTING ONLY and
SHOULD NOT BE LEFT BYPASSED.
•The agitator should agitate every
time the touch screen is closed
properly.

11
Ice Chute Agitation Safety
•There is a magnet located at the top of the ice chute that must come within certain
proximity of a sensor located above the ice chute assembly to initiate agitation. This is
achieved when a customer actuates the ice dispense lever.
•The ice chute sensor is located directly above the ice chute. *May be difficult to see*
•The ice gate pin must be inserted into the ice chute properly to help guide the magnet
into place while at the same time opening the ice gate to allow ice to dispense.
•If the ice gate is not installed properly the magnet will fall forward not allowing
agitation.

12
Ice chute removal
•Optional: Open the door and remove thumb screw and upper nozzle cover
–NOTE: The outer ice chute can also be removed without removing the upper nozzle
cover
•Carefully spread both tabs at bottom of outer ice chute. Remove outer
chute mechanism by pulling upwards and forward sliding barrel magnet
off of ice gate
Tabs at bottom of outer chute

13
Ice chute re-installation
•Slide encapsulated magnet over ice gate pin
•Before snapping outer ice chute back into place make sure tab on outer
chute is placed below top of inner chute
•Push bottom of chute to snap locking tabs in place
•Note: Improperly installed ice chute will prevent ice agitation / dispense
•If ice dispense rate is too fast or slow, restrictor plate can be adjusted up or
down or removed by loosening inner chute screws

• Dispenser control allows “process of
elimination” troubleshooting of most
electrical components.
•Utilizing a multi-meter to verify e-board
output voltages to suspect component
eliminates guess work.
•Control is common to both models
•Error LED indicator
•Common board for all IDC platform units
•Most common Error on IDC is a solid LED
indicator. Carbonator pump run time error,
•Requires soft shut down of Touch screen
and Power to be cycled on dispenser to
reset

Agitation Timing
•Automatic ice agitation timing is factory set for cubed ice and will agitate 4 sec / 1 hour
•You MUST adjust agitation timing when you are dispensing soft ice to .5sec / 3 hours.
•ON Timing–Rotate all the way to the left (min). OFF Timing –Rotate all the way to right
(max)
•Cornelius does not provide a bin stat for ice makers not manufactured by Cornelius. You MUST
install a bin tat to control proper ice level to 4-6” below the top of the hopper
