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.

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.

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.

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.
