SUB-ZERO MODELS 315I AND 315IP OPERATION
ICE CUBES
T
he ice cubes are tapered cylinders about 1
1
/4"
(32) in diameter at the widest end; taper down
to 1" (25) wide at the top; and are 1
1
/8" (29)
h
igh. When the ice maker is adjusted properly,
there should be a
1
/4" (6) indent in the base of
the cube. The ice will appear wet when fresh
and may also develop frost on the outside and
look cloudy. This is normal. The frost will
disappear when liquid is poured over the ice.
ICE STORAGE BIN
All restaurant-type ice makers, such as the
Model 315I(P), operate on this principal: The
ice storage bin is not refrigerated; instead it’s
heavily insulated, much like a picnic cooler or
ice chest. If the ice storage bin were to be
refrigerated, the ice would freeze together into
one very large cluster of ice and would begin
to evaporate. This would yield ice that is very
poor in quality and difficult to remove from the
ice maker.
The Model 315I(P) will continue to operate
until ice builds up high enough to contact ther-
mostat sensor tube in the ice storage bin; then
it will shut off. Models with a drain pump will
occasionally pump out melt water when the ice
maker is off. The pump will only be on for a
few seconds.
RUN TIME
The amount of time the Model 315I(P) will run
to replace melted ice is about two hours per
day. The amount of time the ice maker will run
to replace ice removed is dependent upon how
much ice is removed, how clean the ice maker
is, the surrounding air temperature and the
temperature of the water supplied to the ice
maker. An empty ice maker will usually take
about 24–36 hours to refill.
ICE MAKER OPERATION
INITIAL START-UP
1
)
R
emove the control box cover.
2)
Rotate timer shaft clockwise until the cam is
in the harvest position (switch button out).
3)
Turn on the water supply.
4)
With unit plugged in, rotate the ice maker
control knob to the ON position.
5)
Allow the ice maker to operate for one hour,
and check the size of the cubes; if they are
not correct, adjust as recommended on
page 18.
6)
After the cubes are confirmed to be the
correct size, replace all panels.
USING YOUR ICE MAKER
The ice maker is extremely simple to use; by
turning the ice maker control knob to the ON
position. The Model 315I(P) will automatically
begin to produce ice and will continue to do so
until the ice storage bin is full.
Use the scoop to remove ice and place the ice
scoop in the holder provided (do not leave the
scoop on the ice, as it will gradually disappear
into the ice).
The Model 315I(P) will release a batch of eight
ice cubes about every 30 minutes. At the same
time the cubes fall into the ice storage bin,
water will be entering the ice maker and
draining out.
IMPORTANT NOTE:
Do not store anything in
the ice storage bin other than ice; items like
wine or beer bottles are not only unsanitary,
but labels may also slip off and plug the drain.
