AVANTCO 194MC35022FA Modular Ice Machine

Safety Instructions

1. Connect the ice maker to a dedicated electrical circuit to prevent power fluctuations and potential circuit breaker trips.
2. Use a grounded outlet with the correct voltage. Do not use an extension cord.
3. Do not immerse cords, plugs, or the equipment in water or other liquids. Keep cords away
   from wet areas and avoid hanging over counters to prevent tripping hazards. Replace cords only with the manufacturer’s cord set.
4. Instruct and train users in safe and correct Ice maker operation.
5. Do not modify the Ice maker’s settings or components outside of the manufacturer’s specifications.
6. Ensure all operational or safety labels are visible and legible. Do not remove any labels.
7. Do not store volatile or flammable substances in the Nugget Ice maker to prevent explosions or fire.
8. Regularly inspect the Ice maker for signs of wear, damage, or malfunction, and address any issues promptly.

Modular Ice Machine

Installation Steps

• Check to see if the ice machine is in good condition and the accessories are all present; check the machine model and the machine nameplate.
• Clean the ice storage bin and the food area inside with a sponge soaked in warm water and soap. Then rinse with potable water and dry.
• It requires good ventilation, so the ice maker must have e ventilation space of more than 8” in the rear, 6” on the sides, and 12” in the front.
• Connect the machine to the water supply using the 3/4” inlet fitting supplied with the machine.
• Connect the drain line to the drain connector.
• Any joint in the drain line must not be higher than the machine drainage port; any joint in the drain line cannot be higher than the previous joint.
• Confirm the power requirements stated in the machine’s nameplate; ensure that the power supply meets the requirements.
• Turn off the switch on the power line and connect the machine to the power source.

Getting Started

• Before you start up the machine, please check and confirm:
• The ambient temperature, water temperature, and pressure of the water supply meet the above requirements.
• Start up: turn on the power switch. After powering on, the machine begins to make ice automatically.
• For normal operation, please confirm:
• There is water in the water trough, and no overflow occurs.
• The pump is working properly, and water is flowing evenly in the evaporator.
• The compressor is running normally, and the temperature of the evaporator and the ice-making water is gradually decreasing.
• For air-cooled machines, make sure the fan is running normally, and there is a stable air flow in
  the inlet and outlet of the ice machine;
• The ice machine has no abnormal noise.
• The ice machine has no abnormal vibration.
• It takes about 10 to 20 minutes to make one batch of ice, depending on the ambient temperature and the temperature of the water. The higher the temperature is, the longer the ice-making will take.
• Ice cubes can be properly harvested from the machine.

Operation Instructions

Startup

• After proper installation, connect the water source and turn on the power supply to turn on the machine. Please confirm that the machine is operating normally when you turn it on for the first time.

Self-check

• With power on for the first time, the ice maker will do a self-check and pump out any remaining water.

Preparing

• After the ice machine has finished the self-check, the inlet valve opens, and the inlet water will flow in until it reaches the set level; then the ice maker will defrost once.

Ice making

• After pre-cooling for 30 seconds, the water pump starts, the water flows through the evaporator smoothly and evenly, and the ice cubes are gradually formed in the ice cube tray.

Ice Harvest

• After the ice-making process finishes and the water pump is turned off, the defrosting valve is turned on. After the hot gas enters the evaporator for about 1-2 minutes, the ice cubes slide from the evaporator into the storage bin.

Shutdown

• The ice maker will stop working when you push the “on/off” button on the control panel during the running process.

Bin full stop

• When the ice machine is running and the storage bin gets filled to the machine’s sensor, the machine will take 40 seconds and then stop producing ice.

Repeat ice-making

• When the ice cubes that are triggering the sensor are spread out or moved, the ice maker will go back to the ice-making process in a few seconds.

Control Panel

LED Display

• Self-check: Display “ini” code.
• Preparing: Counts (in seconds) forward.
• Ice making: Counts (in seconds) forward before the water reaches 32 degrees F. Counts seconds backwards to 0 seconds afterwards.
• Ice Harvest: Counts (in seconds) forwards.
• Clean: Display “CLE” during cleaning and descaling; Display “STL” during sanitizing; Display “RIN” during rinsing.
• LED Lamps: Turns lights on/off
• Ice cube thickness adjustment: During the ice-making process, if you are not satisfied with the ice thickness, press the Ice cube–” button for 3 seconds, then click the button “+” or “-” on the panel to adjust the thickness of the ice cube.
• Cleaning: During normal operation, hold the cleaning button for 3 seconds to enter the cleaning process. During the entire cleaning process, cleaning agents and disinfectants need to be put into the water trough. When the cleaning process is finished, the ice maker will go into the ice-making process.
• ON/OFF: Press this button to switch the machine ON/OFF.
• Please open and close the storage bin door gently. Do not slam the door. Keep the door closed when not removing ice.
• If the ice maker is not in use for a long time, it should be energized and run for 2 to 4 hours every 2 months.

Special Protection

• If the ice machine has not detected ice harvest in three cycles, it will shut down for safety and protection. The ice maker needs to be checked.
• If the ice machine detects that the ambient temperature is too high, it will stop for safety and protection.
• The fault code and its comments are displayed as follows:

Maintenance

Exterior Cleaning

• Frequently clean the environment around the ice machine to keep it clean.

Do not block the vents.

• The outer enclosure should be cleaned with a mild detergent and then wiped clean. If necessary, use commercial stainless steel cleaners and polishes.

Inlet Water Filter

• Rinse thoroughly with water. Repeat this process with a water and sanitizer solution.
• Note: Check and confirm that the water pressure is lower than the maximum allowed pressure.
• Do not flush the part above the water pump or the evaporator directly for water protection.

Condenser

• Use a soft brush or a vacuum cleaner with a brush to brush it up and down along the fin direction, to avoid damage to the fins and further affecting the cooling effect.

Water Line

• In order to ensure food safety, the water line of the ice machine should be cleaned regularly.

Winterizing

• Turn off the water and power supply, drain the residual water from the water trough inlet pipe and drain pipe.

Clean Function

• Turn on the ice maker; push the “clean” button for 3 seconds, and the ice maker will begin the cleaning process.
• Put in the proper amount of cleaning solution manually into the water trough, followed by the cleaning and sanitizing process instructions.
• Push the “clean” button. The ice maker will do auto auto-clean for about 15 minutes.
• Please spray the evaporator with the cleaning solution in the meantime to ensure a complete clean.
• When finished, the LED display will flash “Clean” slowly again.
• Put in the proper amount of sanitizing solution manually into the water trough, followed by the cleaning and sanitizing process instructions.
• Push the “clean” button again, and the ice maker will do auto-sanitizing for about 15 minutes.
• This process will take about 5 minutes, and do 5 rinsing cycles. Refer to your cleaner and sanitizer for proper mixing & coding instructions.
• The ice maker will go back to making ice as soon as the cleaning process ends.
• Please throw away the next batch of ice in case of residual cleaner.
