1)Open the door and turn the ice maker control knob to OFF. Refer to the illustration on page 19 for location of the control knob.

2)Scoop out all of the ice; either discard it or save it in a ice chest or cooler.

3)Pour four ounces of Sub-Zero ice maker cleaner into the ice maker reservoir (see side note).

4)Turn the ice maker control to ON.

5)Allow the ice maker to operate for about two hours.

6)Pour hot water 95˚F–115˚F (35˚C–45˚C) into the ice storage bin to melt the ice that has formed. That ice will likely be white and frosty looking.

7)Clean the ice storage bin liner of mineral scale by mixing some ice maker cleaner and hot water, using that solution to scrub the scale off of the liner.

8)Rinse the liner with hot water.

9)Sanitize the ice storage bin interior.

10)Replace the ice removed in step 2. The ice scoop should be washed regularly; wash it just like any other food container.

W I N T E R I Z I N G

1)Clean the ice making system.

2)Turn off the water supply.

3)Drain the water reservoir. Remove the pump hose.

4)Disconnect the incoming water line at the inlet water valve.

5)Remove control box cover and turn the timer into the harvest cycle.

6)With the ice maker operating, blow air through the inlet water valve; a tire pump could do the job.

7)Drain pump models should have about one-half gallon of RV antifreeze (propylene glycol) poured into the ice storage bin drain.

IMPORTANT NOTE: DO NOT use automotive

antifreeze.

8)Replace control box cover. Turn the ice maker OFF and unplug the unit.

To use the ice maker after winterizing, recon- nect the pump hose and water line. Repeat the initial start-up steps outlined on page 15.

Sub-Zero ice maker cleaner contains acids. These compounds may cause burns.

If swallowed, DO NOT induce vomiting. Give large amounts of water or milk. Call a physician immediately. In case of skin contact, flush with water. Keep out of the reach of children.

I C E M A K E R ADJUSTMENTS

There are three items that may be adjusted: cube size, storage bin ice level and harvest time.

IMPORTANT NOTE: Cube size and harvest time adjustments should only be done by a Sub-Zero authorized service center technician.

C U B E S I Z E A D J U S T M E N T

The cube size control should only be adjusted to bring the ice cubes to the correct shape; the overall size cannot be adjusted. Try to adjust the cube size control when the ice maker is in the harvest cycle, or in the first ten minutes of the freeze cycle.
