Location:

The unit can be built into a cabinet as the air flow is in and out the front. The front of the machine must not be blocked. Certain maintenance or repair procedures will require removal of the top, back and side panels, so plan ahead for service and maintenance needs.

Spacing:

No additional spacing is required at the top or sides. However, suggested minimum side clearance for installation is 1/8 inch or 3 mm and suggested minimum top clearance is 1/4 inch or 7 mm.

Allow 4 inches (100 mm) minimum space at the back for the utility connections. Do not block louvers at the front of the cabinet.

Unpacking and Setup

Remove all shipping and packing materials that may be in the ice storage bin.

The unit can be installed with or without legs. The cabinet is equipped with small bumpers on the base to allow placement without legs.

An optional floor mounting kit is also available to fill the gap between the machine and floor if not using legs.

If using legs, carefully tip the machine and install the legs by screwing them into the leg sockets in the bottom of the machine. For reference, the thread size is 5/8 - 11.

If the machine has been tipped onto its side or back allow 1 hour before starting the unit for the oil in the refrigeration system to return to the compressor.

Place the machine in its intended location and level it front to back and left to right. If using legs, adjust their feet in and out to level the cabinet.

If legs are not used the bottom edges of the cabinet must be sealed to the floor to pass most codes.

If built into a cabinet, the adjacent cabinet walls will provide the means for containment. There are no means for attachment to the cabinet.

Be sure to remove the plastic covering the exterior panels, if left on it will be much harder to remove later.

Connect the Water Supply

Plumbing information:

• The water supply connection is at the back panel. It is a 5' (1.5 meter) 1/4 inch (6.35 mm) OD plastic tube.
• A hand actuated valve within site of the machine is required to isolate the unit when it's being serviced.
• The machine has a built-in back flow preventer (an air gap between the water's entry point and the top of the reservoir water), no additional back flow preventer is needed.
  • Water flow rate into machine is .125 gal/min
  Units that are built into a cabinet:

Include a loop or coil of tubing between the water supply and the connection on the ice machine. When the machine is pushed back into the cabinet the tubing will coil and not kink.

Connection Information:

Important: connect to potable water supply only. Open the hand water valve to flush water through the connection point before connecting to the ice machine.

1. Cut cable ties securing hose and power cord to unit.
2. Connect to cold, potable water using the necessary adapters for the 1/4 inch OD plastic tube.
3. If using compression fittings they require a ferrule or sleeve and insert.
4. A female 3/8 compression adapter x 1/4 OD compression allows connection to a typical 3/8 OD compression angle valve.
5. Another connection method is by quick connect fittings.

Note: Do not use a piercing-type saddle valve to connect to the building's water supply. Valves of that type restrict water flow and clog easily.

Connect the drain

The drain connection is at the back panel. The fitting size is 34 FPT. And it is plastic. Do not overheat.

• Drain tube material must be rigid and meet local code.
• Traps in the bin drain line without vents ahead of them will cause poor draining

• The drain must be vented if there is a long horizontal run 5 feet or more. All drains are gravity and must have a minimum fall of 1/4'' per foot of horizontal run.

• Connect rigid tubing to this fitting and vent it at the machine, use an 8 inch or 200 mm vertical tube for the vent.

• Slope drain tubing down from the ice machine to the building drain and the slope must be at least 14 inch per foot or 20 mm per meter.
• Insulate the drain tubing to reduce condensation and is recommended for environments that have high humidity.

Due to the potential for leaks, condensate pumps are not recommended.

Connect the Power

This is a cord-connected unit, and must be connected to its own dedicated power supply. Check the dataplate on the back of the machine to confirm the voltage and per the dataplate use fuses or HACR circuit breakers.

Power Cord:

This 115 volt model is equipped with a cord and 5-15P plug.

Follow All Local Codes

- This Unit Must Be

Grounded. Do not use extension cords and do not disable or by-pass ground prong on electrical plug.

Plug the power cord into the proper power supply.

Note: Electrical outlets can become worn and the power supply can then be erratic. Have it replaced if the connection is loose.

After utility connections

1. Level the cabinet, use the leg levelers on the end of the legs to adjust to cabinet height. Legs should have been installed when the unit was unpacked.
2. Wash the bin and door. If desired, the interior of the bin could be sanitized.
3. Locate the scoop, wash it and have it available for use when needed.

Installation check list

• Has the machine been installed indoors in an environment suitable for it?
• Have all of the shipping items and packaging been removed?
• Has the plastic covering the exterior panels been removed?
• Has the water supply been connected and confirmed to not leak?
• Has a properly sized and sloped drain tube been attached?
• Has the correct voltage power supply been connected?

UF0915, 1415, 2020 and UN0815, 1215, 1520 User Manual

Initial Start Up

1. Remove the front panel by removing the two screws holding it to the cabinet and pulling the panel down and off the machine.
2. Turn on the water supply, correct any leaks.
3. Locate the On push button.

1. Confirm that the Power indicator light is on and that the Water indicator light is off.

If the Water indicator light is blinking red, the unit will not start as there is no water sensed and ice cannot be made. Correct any condition keeping water from filling the reservoir.

1. Push and release the On button.
2. The Status indicator light will be on. Warm air will begin to blow out the left front of the machine and the auger drive motor will switch on. Within a minute or so the ice will fall down and slide into the ice storage bin. It is normal for a small amount of water to also drip from the ice making area.
3. Check for any unusual noises, such as fan motor vibration and correct as needed.
4. Return the front panel to its normal position.

Use and Operational Notes

To use, simply lift the door by its bottom edge and slide it up and into the top of the machine. Use the scoop to remove ice and close the door.

The machine will make the most ice if it has plenty of room to breathe. This is an air cooled product and it must be able to take in room air and discharge air heated by the ice making process.

Blockage of vents or exposure to excessive heat will reduce the ice making and storage capacity.

The storage bin is insulated but not refrigerated, so ice will melt during use. That is normal and assures that fresh ice is available in the bin.

The fan will make some noise during operation, however rattles and other vibrations are not normal and should be attended to.

If the machine is in a space colder than the minimums listed it can become damaged.

Caution: The cabinet is not designed to support anything placed on it. Do NOT step or stand on it.

On and Off

The On and Off buttons are located behind the louvered front panel. Remove that panel to access those buttons.

To Shut Off: Push and release the Off button and the unit will begin a shut down. Push and hold the Off button for an immediate shut off.

Status Indicator Light

Glows green when either making ice or when the bin is full of ice (optical sensors blocked by ice).

Clean Indicator Light

Serves as a reminder that it is time to have the unit cleaned. Normally off. This light glows after 6 months of power up time between cleanings. It will go out after the unit has been cleaned using the process in this manual and / or the one on the ice machine's cleaning label.

Water Indicator Light

Normally off. It glows when there is power to the unit but no water sensed in the reservoir. A lack of water will trigger a unit shut down. The unit will automatically restart after water has been restored.
