Control Panel

Installation

1. When handling, keep the cabinet upright with the inclination not exceeding 45 degrees. Do not invert the machine or lay it horizontally.
2. There are rotating components in this ice machine. Do not insert slim objects into ventilation or exhaust ports, or serious mechanical damage and injury may occur.
3. Do not store volatile or flammable substances in this ice machine, as it may result in an explosion or fire.
4. Do not store any sundries or freeze any food in the storage bin. Keep the ice scoop clean.
5. The ice machine must be placed on a floor sufficient to support its weight. An insufficient base may cause the equipment to fall over and cause injury.
6. There should be sufficient ventilation space around the ice machine.

Installation Steps

1. 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
2. Connect the machine to the water supply using the 3/4″ inlet fitting supplied with the machine. It is
   recommended to install a water ball valve (not supplied with this machine) on the water supply line.
3. Connect the drain line to the drain connector.
4. Confirm the power requirements stated in the machine’s nameplate; ensure that the power supply meets the requirements.
5. A circuit breaker or switch with a leakage protector and reliable grounding is required.
6. Turn off the switch on the power line and connect the machine to the power source.

Modular Ice Machine

The ice machine should be installed in a proper location meeting the following conditions.

• Indoors, ambient temperature: 40-90°F.
• Power supply: The rated voltage indicated on the machine nameplate is ±6%.
• Water source: Potable water, with water pressure from 18.75 PSI to 80 PSI; water temperature: 40 90°F.
• The ice machine should be kept away from heat sources, an extremely high or low temperature environment, and direct sunlight.
• There should be sufficient ventilation space around the ice machine; the distance from the ice maker to the wall should be no less than 12” for the front, 6” for the sides, and 8” for the rear.
• The ice machine must be placed on a floor sufficient to support its weight.
• The socket for the ice maker must be reliably grounded and include leakage protection.
• Proper floor drainage must be provided near the installation location of the ice machine.e

Schematic Diagram

Start-Up

1. Before you start the machine, please check and confirm.
   • The ambient temperature, water temperature, and pressure of the water supply meet the above requirements.
2. Start up: Turn on the power switch. After powering on, the machine begins to make ice automatically.
3. For normal operation, please confirm:
   • Look behind the finger curtain at the back of the ice storage area to check that water is spraying on the evaporator nubs after 30 seconds in MAKE mode.
   • 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 stable airflow 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.

194UCB77A – Adjusting Ice Thickness

• This unit does not have a digital adjustment for thickness. It uses the water level to determine how much water is used to make ice, which controls the thickness.
• To change the thickness of the ice:

1. Pull up on the adjuster nut to loosen it from the stem and allow it to turn.
2. Turn the adjuster nut so that the stem gets longer to make thinner ice. Internally, the float moves up in the trough. This turns HARVEST mode on sooner.
3. Turn the adjuster nut so that the stem gets shorter to make thicker ice. Internally, the float moves down in the trough. This turns HARVEST mode on later.
4. Once set, push the adjuster nut back down to lock it in place.
5. Do not set the thickness based on the first run of the unit after initial setup or after being on standby. The first cycle is typically not the same as the successive cycles.

Operating Instructions

1. The unit starts counting down from 135 to 0 in PREP mode.
   • The INLET valve allows water to overflow through and drains water to clear the system.
2. The unit starts a count-up from 0 to 200.
   • It goes through a HARVEST cycle. The INLET indicator will light for the first part of the cycle to feed water into the system. Some water may drain during this cycle.
3. The unit enters MAKE mode.
   • It counts up from 0.
     1. From 0-30, the system starts to cool the evaporator.
     2. At 30, the circulating pump turns on and stays on for the duration of the MAKE cycle.
   • The MAKE ending point is based on when the water level sensor reaches its bottom position.
     1. The water does not refill during MAKE mode.
     2. The water pump runs to spray water onto the evaporator nubs where ice forms.
     3. The height of the water level sensor determines ice thickness.
4. When the unit hits 200, it starts back at 0 with another MAKE cycle and continues to go from MAKE to HARVEST cycles in this manner.
5. If the digital display reads “FUL”, the ice bin is full. Ice is lying against the full switch on the left side of the bin. The user will need to remove existing ice or redistribute ice away from the switch to allow the unit to continue to make ice.

LED Display

• • Self-check: Display “ini” code.
  • Preparing: Counts (in seconds) forward.
  • Ice making: Counts (in seconds) forward prior to the water reaching 32°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.

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 OFF/ON.
• 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.

Maintenance

Exterior Cleaning

• Frequently clean the environment around the ice machine to keep it clean. Do not block the vents.
• If necessary, use commercial stainless steel cleaners and polishes.

Inlet Water Filter

• The water filter should be inspected regularly.
• It is recommended to replace the filter cartridge every
  3 to 6 months.

Interior Cleaning

• The inside of the ice storage bin can be washed with water and a cleaner solution.
• Rinse thoroughly with water. Repeat this process with a water and sanitizer solution.

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 affect 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, and drain the residual water from the water trough inlet pipe and drain pipe.

4-6 Month Cleaning Process

1. Turn off and unplug the machine from the power source.
