Scotsman Ice SCN60 User Manual

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.

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.

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

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 90

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.

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.

SCN60 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

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.

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.

Air Intake

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.

Plumbing - Pump Model

Drains

There are two types of ice machine models, one that drains by gravity and one that has an internal drain pump.

Drain Pump Model drain installation

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 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.

Water Supply

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.

Plumbing: Gravity Drain Model

Caution: Restrictions in the drain system to the machine will cause water to back up into the ice storage bin and melt the ice. Gravity drain tubing must be vented, have no kinks and slope to the building drain. Air gaps are typically required by local code.

1. Place the ice machine in front of the installation opening. Adjust leveling legs to the approximate height.

2. Remove the upper back panel if needed for access to the drain fitting.

Note: If you are connecting a gravity drain model and the drain opening has been located in the floor under the base pan according to the pre install specifications, follow steps 3 through 5 to drain the unit through the base. If not, proceed to step 6b.

3. Remove the clamp and barbed elbow and take off the plastic cover in the base pan below the drain hose.

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 about6-7 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.

SCN60 Installation and Use

Use

No special instructions are needed for use. Just take as much ice as you need, the machine will replace it. A scoop is provided, and it can be stored in the machine using the loop of tubing on the right side as a holder.

The machine can be shut off anytime by just pushing and releasing the On/Off button.

What shouldn’t be done?

Never keep anything in the ice storage bin that is not ice. Objects like wine or beer bottles are not only unsanitary, but the labels can slip off and plug up the drain.

Never allow the machine to operate without regular cleaning. The machine will last longer if it is kept clean. Regular cleaning should happen at least once per year, and preferably twice. Some water conditions will dictate even more frequent cleaning of the ice making section, and some carpets or pets will dictate more frequent cleaning of the condenser.

Noise:

The ice machine is designed for quiet operation, but will make some noise during the ice making cycle.

Ice Making

During ice making, nugget ice will drop into the bin at an irregular rate; sometimes there will be little ice falling while at other times a group of nuggets will fall. Some water drops may also come out with the ice. Both conditions are normal.

Note: The Time to Clean light will switch ON after 6 months of use. It will remain ON until the ice making system is cleaned using the process on page 14.
