Startup and Operation
1. Pre-Installation Checks:
• Verify the nugget ice maker's condition before installation.
• Confirm the model and nameplate of the machine.
2. Cleaning:
• Clean the ice bin and interior of the machine with a sponge soaked in warm water and baking soda.
Rinse and dry thoroughly.
3. Placement and Ventilation:
• Place the air-cooled nugget ice maker in a well-ventilated area, maintaining a ventilation space of
2” on both sides.
• Adjust the legs at the bottom of the machine for leveling and ease of floor cleaning.
4. Water Connection:
• Connect the water filtration system (if applicable) in accordance with all applicable state and local
laws and regulations.
• Note: The water inlet and outlet directions are typically marked on the manifold head or cartridge.
Install the filter in the correct direction.
• Note: To continuously filter impurities, the filter cartridge must be replaced in accordance with your
water filtration system's instructions.
• Connect the machine to the water supply pipe using the 1/2’’ joint provided. It is recommended to install a
water valve (not provided) on the water supply pipe.
• Connect the supplied drainpipe to the drain port, ensuring the drainpipe has a drop greater than 1” to
facilitate drainage. Ensure the drainpipe is not blocked and no section of it is higher than the drain port or
any previous section.
5. Before Startup:
• Ensure all accessories or items have been removed from the nugget ice maker.
• Ensure the nugget ice maker has been standing upright for 24 hours.
• Ensure the water pipe is connected and the water valve is open.
• Ensure the plug is connected to the power supply and the power switch is turned o.
• Confirm the ambient temperature, water temperature, and water supply pressure are within the specified
ranges.
6. Startup:
• Turn on the power switch on the power supply line.
• When the machine is powered on, press the “Power” button on the display panel. The machine will enter
automatic ice-making mode.
7. Operation and Inspection:
• During normal operation, ensure that ice falls o normally, the fan works properly, and there is no abnormal
noise or vibration.
• Note: If exposed to thunderstorms or not in use for a long time, disconnect the power supply and
water source.

8. Ice Making Process:
• After powering on, press the “Power” button on the display panel. Following a 10-second countdown, the
balance valve, reducer, fan, and compressor will start in sequence.
• The continuous water flow is stored in the inner wall of the evaporator, where it freezes. The ice is then cut
by the auger driven through the reducer and taken out through the spiral ice blade.
• Water Shortage Restart: If water is insucient, the “low water level” indicator will be ON. When normal
water supply resumes, the indicator will turn OFF. After some time, the machine will restart and the “water
shortage restart” indicator will be ON, turning OFF automatically after 10 hours of normal operation.
9. Shutdown:
• To shut down, press the “Power” button on the panel. The compressor will stop immediately and after a
60-second countdown, the auger and fan will shut down, turning the machine OFF.
• Automatic Shutdown with Full Ice: When the ice bin is full, the machine will detect the blockage between
the infrared transmitter and receiver of the full ice switch and automatically stop running after 60 seconds.
• Ice Making Recovery After Ice Removal: As ice is removed from the ice bin, the machine will detect the
decreased ice height and resume normal ice making after two minutes.

Professional Servicing
Before making a service call due to any abnormalities, ensure the following checks are performed:
1. Check the Water Source:
• Verify that the LED "low water level" indicator on the display panel is always ON.
• Ensure the water pressure in the nugget ice maker is between 18.75 PSI to 80 PSI, and the water
temperature is between 40-90°F (5-33°C).
• Confirm that the water valve is open.
• Check for any water leakage.
2. Check the Power Supply:
• Ensure that the indicator on the display panel is ON.
• Confirm that the display panel does not show an OFF status.
• If the LED indicator on the display panel is ON, check the condition of the power plug and socket, and
ensure that the switch on the power supply line and the circuit breaker on the back are ON.
3. Check the Nameplate and Machine Number:
• Examine the nameplate on the side face of the nugget ice maker and record the model and number.
NOTE: On-site services requested for reasons such as no water, no electricity, or environmental factors, rather than
faults with the machine, will be chargeable.

General Information
Ice dispenser 194HBN12022 is 22" wide and designed for use with Avantco ice cube machines
194MCF322A/194MCH322A/194MN522A or 194MCF422A/194MCH422A for ice production.
Ice from the nugget ice machine 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.

Product Description
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 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 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 that spills during vending. 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. The side and front exterior panels are stainless steel. The vending area and top panel
are made of plastic.

Unpacking
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 pallet, place part of the carton behind the unit and tip the unit on its back. Remove the bolts holding
the pallet to the base of the HBN dispenser and separate the pallet from the unit.
Install the legs into the base of the unit, using the holes where the pallet bolts were. Turn the leg levelers 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 drain lines
and electrical connections will be made.
Front Panel Removal

panels by strikes and latches. The top panel keeps the front panel from moving forward.
To remove:
1.
Disconnect electrical power.
2.
Remove the two screws holding the top panel to the dispenser. Lift the top panel up and over the dispenser.
3.
Pull the top edge of the front panel forward until the two snaps disengage.

Installation - Plumbing
DRAIN
All models of the dispenser have a ¾" FPT drain fitting at the bottom of the back panel. Connect ¾" 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 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 recommended for the tubing.
