STARTUP AND OPERATION

1. Before starting up the ice maker, please check and confirm the following:
   • All packing materials have been removed.
   • All accessories have been removed from the ice bin.
   • The unit is properly leveled.
   • The water pipe is securely connected and the valve is open.
   • The plug is properly connected to the power supply outlet and the unit’s power switch is in the ‘Off’ position.
   • The ambient temperature, water temperature, and water pressure meet the requirements.
2. Turn the power switch to the ‘On’ position to start the ice maker. Once turned on, the unit will automatically begin making ice.
3. For normal operation of the unit, confirm the following:
   • There is water in the water trough and no overflow is occuring.
   • The pump is working properly and water is flowing evenly on the evaporator.
   • The compressor is running normally, the temperature of the evaporator and the ice making water is gradually decreasing.
   • For air cooled machines, verify the fan is running normally, and there is stable air flow in the inlet and outlet of the ice machine.
   • There are no abnormal noises or vibrations.

It takes about 10 to 20 minutes to make one batch ice, depending on the ambient temperature and the temperature of the water. The higher the temperature is, the longer the ice making will take. When you turn the power switch ‘On’, the unit will run a self check and pump any water out of the system. The inlet valve will then open and the water trough will fill up with water and the unit will pre-cool the evaporator for about 30 seconds. Water then flows over the evaporator to be frozen into ice cubes, which are then dropped in the Harvest cycle when the defrost valve turns on allowing hot gas to flow into the evaporator, freeing the ice to drop.
WARNING : DO NOT put your hand into the ice bin while the ice is dropping.
When the ice bin is filled to the point where the ice sliding board cannot return to its normal position, the ice making process will stop until the ice has either melted enough to let the board fall into position, or ice is removed from the bin. Once the bin is clear, the ice making process will resume.

CARE AND MAINTENANCE

NOTE : Maintenance must be done by a qualified service technician.
WARNING : Before maintenance or cleaning can be performed, the water supply should be shut off and the unit should be disconnected to the power supply.

EXTERIOR CLEANING

ALWAYS make sure to keep the area around the ice maker clean, and that nothing is blocking the vents. Clean the exterior of the unit with a mild
detergent and wipe clean. If necessary, use a commercial stainless steel cleaner or polish.
NOTE: Stainless steel may rust without proper care and maintenance.

INTERIOR CLEANING

Clean the inside of the ice bin with clean, potable water and wipe as needed. For the air-cooled ice maker, the condenser should be cleaned every three weeks. 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. The condenser filter should be removed and carefully cleaned every 2 weeks.
NOTE : Be careful when doing the condenser cleaning as the edges of the fins are sharp.

INLET WATER FILTER
The filter should be inspected regularly and replaced every 1-3 months based on usage and water quality.

WATER PIPE
To ensure food safety, the water pipe should be cleaned regularly.

WINTERING:

If the unit is not going to be used for a long period or stored away, turn off the water and disconnect from the power supply. Clean the interior and exterior of the unit, and be sure to drain all water from the water trough, inlet pipe, and drain pipe.

CLEAN FUNCTION

NOTE : ALWAYS empty the ice bin and make sure there is no ice on the evaporator before running the cleaning function.
NOTE : ALWAYS clean and sterilize the ice bin, ice sliding board, water distribution pipe, water supply pipe, and water pump, then rinse completely.

• Turn on the ice maker and push the “Clean” button for 3 seconds. Put the proper amount of commercial ice maker cleaning or descaling solution into the water trough manually per the products instructions, let it sit there for about 1 minute, then push the ‘Clean’ button again. The ice maker will enter the cleaning process and will run an auto clean cycle for about 15 minutes. Spray the evaporator with some solution while this is running to ensure complete cleaning. When finished, the “Clean” LED will flash slowly.
• Manually put sterilization solution into the water trough per the product instructions and press the “Clean” button again. The process will run about 15 minutes. Be sure to spray some of the solution onto the evaporator while this is running to ensure complete sterilization.
• When sterilization is complete, the unit will enter a rinsing cycle that lasts about 5 minutes. This will repeat 5 times.
• When the entire cleaning cycle is complete, the unit will go back into the ice making mode. Allow it to make 5 batches of ice, and be sure to dispose of these first 5 batches after cleaning. It is recommended that the ice maker be cleaned and maintained at least every 4 weeks. Failure to do so may result in the unit malfunctioning. The maintenance of the ice machine or malfunctions due to improper maintenance are not covered by the manufacturer’s warranty.
