CHD22/CHD30 General Description
Page 2
The CHD22 is a 22 inch wide hotel/motel cubed ice dispenser. It is designed to use a
CorneliusCcM0322 or CCM522 cube ice machine as the source for ice.
TheCHD30* is a 30 inch wide version of the CHD22 and is designed to use Cornelius
CCM0330 through CCM0530 cubers as its source of ice. Note: 22 inch wide ice machines
are not for use on the 30 inch wide dispensers.
*Higher capacity cubers, CCM0630, CCM0830 and CCM1030 may also be used, but they
require 230-volt power.
Basic Operation:
Ice from the cuber falls into the insulated hopper, where it is stored until needed. When a
user pushes the dispense chute a rotating wheel scoops the ice up to the top front of the
hopper where there is an outlet to the ice chute. Ice is directed into the users container.
Flaked or nugget ice should not be used in these dispensers.
Do not double stack cubers on these dispensers.
Condensate drain pumps are not recommended for drainage.
This is not a waterglass style dispenser.
Basic Specifications:
Basic models dispense ice when their chute is pushed and will continue to dispense ice until
the chute is released or the bin is emptied. Coin/Token models require a coin or token first.
Tokens are available from Cornelius, the part number for 500 tokens is 620204708. Water
Dispenser models are basic models with a factory installed separate water dispenser.

Models:
CHD22
The Basic version is constructed to deliver ice when the ice chute is pushed in, and it
continues to vend ice as long as the ice chute is held in or until the bin is empty.
CHD30
There are two versions of the CHD30 dispensers: Basic and Coin/token. The Basic version
is constructed to deliver ice when the ice chute is pushed in, and it continues to vend ice as
long as the ice chute is held in or until the bin is empty.
The Coin/token version is designed to deliver ice after a coin or token is inserted into the coin
slot AND then the ice chute is pushed in. Ice vending is limited to a preset time per coin or
token use. Coins or tokens are collected in a coin box at the bottom of the dispenser. A keyed
door allows access to the coin box without removing the front panel.
The Basic models of the CHD22 and CHD30 are available in 230 volt 50 Hz electrical for
those countries with that type of electrical service.
Kits: Bin tops and bin thermostats are not required. No other kits are available.

CHD22/CHD30 Product Description
Page
All models consist of a plastic lined, insulated hopper mounted to a metal base. The hopper
contains a 15 blade plastic dispense wheel and a stainless steel sweep arm. The top front of
the hopper has a removable door to facilitate maintenance and cleaning of the hopper without
removal of the ice machine.
The dispense wheel and sweep arm rotate when the ¼ HP dispense drive motor is actuated.
The drive motor’s actuation is controlled by the agitation timer or the vend switch. When the
ice dispense chute is pushed back it moves the actuation lever up. The actuation lever
releases the chute door and pushes the vend switch arm up. When the vend switch arm has
moved a preset distance the vend switch contacts close, providing power to the dispense
drive motor. Ice is delivered to the top end of the ice chute by the dispense wheel and it
slides down the chute to the container below. The container rests on a grill, the grill’s
openings are over the ice catch pan, and any spilled ice goes there. The grill has a flange at
the front to help contain the ice if it spills during vending.
6
After the ice dispense chute is released, the ice chute door closes to stop ice flow. Ice in the
chute will eventually melt. Melted ice water is routed to the drain through a hose
attached to the bottom of the chute. Spilled ice is contained in an
insulated ice catch pan. Melted ice water from the ice catch pan is
routed to the drain. User debris is kept away from the drain in the
catch pan by a slotted shield.
Bin
The side and front exterior panels are stainless steel.
The vending area and top panel are made of
plastic.
Coin / Token Model
The coin op model’s operation is identical to the
basic operation described above with the exception
that no power is provided to the vend switch until the
coin mechanism has activated the vend timer. The
vend timer then allows the vend switch to be
activated for a set time, during that time the user
must dispense the ice. A green “ready” light over
the vending area will glow when the vend timer is
armed and ready for dispensing.

Page 7
After removing the carton, check for the loose-shipped parts packed in the storage bin. The
parts will include a carton with four legs. Remove the leg carton and any other loose-shipped
items.
To remove the skid, place part of the carton behind the unit and tip the unit on its back.
Remove the bolts holding the skid to the base of the CHD dispenser and separate the skid
from the unit.
Install the legs into the base of the unit, using the holes where the skid bolts were. Turn the
leg leveler part of the legs in all the way, adjust them later after the unit is in its final installed
position.
Move the dispenser to an upright position and set it in the location where it will be installed.
Note where the drain lines and electrical connections will be made.
Front Panel Removal
The front panel rests on the base and is located with pins that stick up from the base. It is
retained to the side panels by strikes and latches. The top panel keeps the front panel from
moving forward.

CHD22/CHD30 Installation - Plumbing
Page 8
Drain:
All models of the dispenser have a 3/4" FPT drain fitting at the bottom of the back panel.
Connect 3/4" rigid tubing to this connection, a vent is recommended for most installations.
Route the drain tubing to the building drain.
Note: Drain fitting material is plastic. If using copper, sweat the copper tube to copper
fitting together before installing on the dispenser.
Note: Keep PVC solvent away from all plastic parts of the dispenser.
Follow all applicable plumbing codes.
Because the drain tubing will be very cold, insulation is recommenced for the tubing.

Electrical Sequence
Pushing the ice chute closes a contact to the
gear motor.
The gearmotor will have power and the dispenser will
continue to operate as long as the ice chute is pushed
in. This model also has an agitation cycle of 3
seconds every 6 hours. Since the ice chute is not
pushed in during agitation no ice is dispensed.

CHD22/CHD30 Dispenser Use
Page 11
Basic Model
After the ice machine has operated for a few hours, the CHD dispenser can be used. Pushing
the ice chute back will activate the dispense mechanism and ice will drop out of the chute into
the user’s container.
Coin/Token Model Operation
Without activation the dispenser
will not dispense ice when the ice
chute is depressed.
To activate the dispense system,
the user must insert a quarter or a
token in the coin mechanism. If the
quarter or token is accepted, the
Ready Light above the ice chute
glows green, indicating that ice can
now be dispensed. The dispense
system will allow ice vending for a
pre-set time. Once activated,
pushing the chute in (like the basic
model) causes the ice to vend. At
the end of the pre-set time, vending
stops.
Free Vend: There is a free vend
switch inside the unit, switch it to
ON to bypass the coin mechanism
and vend ice anytime the chute is
pushed back.
When switched to Free Vend the
Ready light will be ON.
When switching from Free Vend to
Coin / Token operation the Ready
light will be ON for a few seconds.
