SCN60
Installation and Use
Introduction
This manual includes information for the installation, operation and maintenance of the SCN60 residential ice machine.
The SCN60 was developed to offer fans of Scotsman’s Nugget Ice form the ability to have that ice in their homes. Previously Nugget Ice was only available in commercial establishments, where it developed a strong following because of the chewable nature of the ice. This machine makes authentic Nugget ice, using the same process as the larger commercial machines.

Outdoor Use Notice:
Keep from freezing. Severe damage will occur to the unit if left in or operated in temperatures beyond the limits listed in this manual. That damage is NOT covered by warranty.
Keep dry. Do not locate in low lying areas where puddles will accumulate.
Provide Shade: Heat gain from the sun will reduce the unit's ability to make and store ice, and ultraviolet radiation from the sun can potentially damage the unit's plastic components.
Water Supply: Avoid a long run of hose or tubing exposed to the sun. Plastic water supply tubing should be rated for potable water and include UV protection. Copper tubing is recommended.
Back Flow Prevention: The unit includes back flow prevention, no additional check valve is required.
Drainage: Do Not drain into swimming pool or onto grounds.

SCN60
Installation and Use
Product Description:
This ice machine is designed to be used indoors, in a controlled environment or outdoors within certain limits.
The SCN60 is made up of two major systems: the ice making system and the ice storage system. The ice making system is a continuous flow type ice machine, it makes ice when the ice level becomes low and stops when it is full.
The ice storage system is an insulated chest with a drain at the bottom for melting ice. It is not refrigerated, insuring that the bin contains fresh ice.
Installation Information
Dimensions:
The cabinet is fourteen and seven eighths inches wide by thirty three and three eighths to thirty four and three eighths inches high.
Utility and Operational Requirements
•The SCN60 must be connected to a potable water supply.
•The water supply must have a conductivity of at least 10 microSiemens/cm.
•Minimum water pressure: 20 psi
•Maximum water pressure: 80 psi
•Minimum water temperature: 40 degrees F.
•Maximum water temperature: 90 degrees F.
It is designed to operate in wide range of air temperatures:
•Minimum air temperature: 50 degrees F.
•Maximum air temperature: 100 degrees F.
Although the machine will function within the listed ranges, it works best at water temperatures between 50 and 60 and air temperatures between 60 and 80.
Note: Ice making capacity goes down as the environmental temperatures go up, and will be severely reduced at temperatures over 90oF.
Operating a unit outside of the limits can cause problems that are not covered by the warranty and, if extreme, cause damage to the unit.
Water Quality
The water to the machine must be potable, or fit for human consumption. Beyond that, water supplies vary in the degree of mineral content. As this ice machine makes ice, all the water that flows into the machine is changed into ice. That includes any minerals that might be in the water. However, during ice making some minerals will stick to the ice making components. The higher the mineral content, the more mineral build up will occur. Water filters are a partial help, as they will remove the suspended solids, but water treatment is needed for the dissolved solids, which are part of the water and cannot be filtered out.
RO Water
This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no less than 10 microSiemens/cm. A reverse osmosis system should include post treatment or blending to satisfy the R.O. water’s potential aggressiveness.
Deionized water is not recommended and could damage the machine.
Because water softeners exchange one mineral for another, softened water may not improve water conditions when used with ice machines
Electrical power
The unit must be on its own 115 volt, 60 Hz, 15 amp circuit. It is equipped with a power cord and can be plugged into a nearby outlet. Extension cords are not allowed by most codes. Follow all applicable codes.
Warranty Information
Warranty information is supplied separately from this manual. Refer to it for coverage. In general, the warranty covers defects in materials or workmanship and does not cover corrections of installation errors or maintenance.

Installation and Use
Location Recommendations:
The machine can be built into a cabinet. It is an air cooled refrigeration system and so air flows in and out of it through the grill at the bottom front. The grill must not be blocked by any covering door or other obstruction.
Drain Conversion: A gravity drain model can be converted to a drain pump model by installing a drain pump kit. The drain pump kit consists of a drain pump, wiring harness and associated tubing. The part number is A39462-021.
Installation Notes
Air Intake
Warm Air Out
There are two models, one is a gravity drain type and it must have a building drain connection below the level of the drain tube at the back of the cabinet; the other is a pump drain model which can force drain water up a maximum of 10 feet, allowing it to be located where a gravity drain isn’t available.
Kickplate Extension: In some situations the leg levelers will be extended enough to become visible. A kit to extend the kickplate over the legs is KKPF.
Cabinet Stability: In some free standing installations it may be prudent to add a bracket that secures the back of the cabinet to a wall. That kit number is KATB.
Built In Situations: If a finished floor is to be installed in the area after the ice machine has been built in, shims the expected thickness of the floor should be installed under the unit to keep the machine level with the planned floor level.
Note: The water connection is at the back and adds a few inches to the cabinet depth. Minimum clearance is 0 in. at the top, 2 in. at the rear and 1/8 in. at each side.
Installations on a slab: Use a pump model and pump the water to the point of drainage. Pump models will pump 1 story (10 feet) high.
Installations over a crawl space or basement:
Either gravity drain or pump model units may be used, if there is not enough room behind the machine for a drain/waste receptacle, the drain will have to be below the floor.
Note: When installed in a corner, the door swing may be limited due to handle contact with the wall or cabinet face.
All models require a water supply. Water supplies vary in the degree of mineral content. High mineral content water will require more frequent maintenance. Water filtration may improve the taste of the ice as well as cut down on some of the mineral build up.

1.Locate the coil of 3/8” ID plastic drain tubing secured to the back of the unit.
2.Route the plastic drain tube from the back of the unit to the drain connection point.
The recommended water supply tubing is ¼ inch OD copper. Stainless steel flex or reinforced PCV tube may also be used. Install an easily accessible shut-off valve between the supply and the unit. This shut-off valve should not be installed behind the unit.
The water connection is at the back of the cabinet. Connect using a compression fitting, one is supplied tied to the water inlet tube. When built in: Coil enough tubing behind the machine so it can be pushed into the cavity without kinking the tubing.
The drain connection point can be as high as 10 feet above the ice machine. The drain pump includes a check valve to prevent re-pumping water in the drain hose.
IMPORTANT NOTE: Often an air gap is required by local codes between the ice maker drain tube and the drain receptacle.

Installation and Use
Electrical and Start Up
The ice machine is supplied with a power cord. Do not remove the grounding pin from the cord’s plug. Do not use extension cords. Follow all codes.
Connect the machine to its own 115 volt, 15 amp circuit.
1.If the electrical outlet for the ice maker is behind the unit, plug in the unit.
2.Position the unit in the installation opening.
3.Turn on the water supply. Make sure that the ice maker is plugged in and the power is on.
4.Slide unit into installation opening, paying careful attention to water supply and drain connections. Do not kink!
5.Pour a couple of quarts of water into the ice storage bin; on drain pump equipped machines the drain pump should start and water should pump out. Check for leaks.
6.Replace the service access panel.
7.Level the unit as needed.
Installation check list:
1.Has the unit been connected to the proper water supply?
2.Has the water supply been checked for leaks?
3.Has the unit been connected to a drain?
4.Has the drain been tested for flow and leaks?
5.Has the unit been connected to the proper electrical supply?
6.Has the unit been leveled?
7.Have all packing materials been removed from the machine?
8.Has the door covering been installed?
Initial Start Up
1.Turn on the water supply and check for leaks.
2.Switch on the electrical power.
3.Push and release the On/Off switch to start the machine. The Ice Making light next to the On/Off switch will glow Green.
Warm air will flow out of the left front grill.
It will take about 10 minutes for the ice machine to begin dropping nugget ice into the storage bin. It is normal for that ice to melt and ice will continue to melt, but at a slower rate. It will take about 6 - 7 hours to fill up the ice storage bin. The bin holds about 20 lb of ice when full.
Ice level control
The ice level control for the SCN60 is an ultrasonic sensor, located above the ice storage area. It is automatic and there is no adjustment to make. When ice melts or is used, and the ice level drops below a preset distance the control turns the ice making system back on. It makes ice until the preset level is reached. Placing your hand in the unit to remove ice does not affect the ice level.
