Scotsman Notes

I have dozens of manuals on hand. So ask and receive my lovelys.

DO THE BASICS:

Change the water filter

Add ice machine cleaner and go by the directions.

What should be kept clean?

There are 5 things to keep clean:

1. The outside cabinet & door.

2. The ice storage bin.

3. The condenser.

4. The ice making system.

5. The ice scoop.

The ice storage bin should be sanitized

occasionally. It is usually convenient to sanitize the

bin after the ice making system has been cleaned,

and the storage bin is empty.

A sanitizing solution can be made of 1 ounce of

household bleach and two gallons of hot (950F. -

1150F.) water. Use a clean cloth and wipe the

interior of the ice storage bin with the sanitizing

solution, pour some of the solution down the drain.

Allow to air dry.

How to clean the condenser.

The condenser is like the radiator on a car, it has

fins and tubes that can become clogged. To clean:

1. Remove the kickplate.

2. Locate the condenser surface.

3. Vacuum the surface, removing all dust and lint.

Caution: Do not dent the fins.

4. Replace the kickplate.

Winterizing

1. Clean the machine as explained on the next

page.

2. Turn off the water supply.

3. Drain the water reservoir. See page 24, Spray

Pump Repair and follow the instructions to remove

the pump hose (step 2, bottom hose only).

4. Disconnect the incoming water line at the inlet

water valve.

5Remove control box cover and turn the timer

into the harvest cycle.

6. With the machine operating, blow air through

the inlet water valve; a tire pump could do the job.

7. Drain pump models should have about 1¤2 gallon

of RV antifreeze (propylene glycol) poured into the

ice storage bin drain.

Note: Automotive antifreeze must NOT be used.

8. Replace control box cover. Switch off and

unplug the machine.

CUBE ADJUSTMENTS

There are three items that may be adjusted: Cube

Size, Harvest Time, and Bin Level. Note: Cube

Size and Harvest Time adjustments should only be

done by a qualified service person.

Cube size control.

The cube size control should only be adjusted to

bring the cubes to the correct shape, the overall

size cannot be adjusted. Try to adjust the cube

size control when the ice machine is in the harvest

cycle, or in the first 10 minutes of the freeze cycle.

1. Open the door and remove the control box

cover.

2. Locate the cube size adjustment screw, and to

make fuller cubes, turn the screw clockwise about

1/4 turn. This will make the freezing cycle longer.

3. To shorten the freezing cycle and make cubes

that are not as full, turn the adjustment screw 1/4

turn counterclockwise.

4. After the next freezing cycle, the cubes should

have responded to the adjustment, if another

adjustment is required, do it early in the freeze

cycle.
