Sub-Zero 315 Ice Maker User Manual


 
ADJUSTMENTS
There are three items that may be adjusted: cube size, bin
ice level and harvest time.
IMPORTANT NOTE: Cube size and harvest time adjust-
ments should only be done by a qualified service person.
Cube Size Adjustment
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
maker 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 coun-
terclockwise.
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.

Winterizing
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 1/2 gallon of
RV antifreeze (propylene glycol) poured into the ice
storage bin drain.
IMPORTANT NOTE: Automotive antifreeze must NOT be
used.
8) Replace control box cover. Switch off and unplug the
ice maker.
NOTE: To use after winterizing, reconnect pump hose and
water line. Repeat the initial start up on page 14.
