INITIAL START UP
12. After an ice harvest check Cube Size. There
is just enough water in the reservoir to make one
full sized batch of cubes. The water pump may
pick up some air at the end of the freezing cycle
and then bubbles in the pump discharge hose are
normal. If the water pump quits pumping water, the
cube size control may be set too cold, or the water
system may be leaking water.
Compare cube size to the "Cube Size Diagram".
To adjust cube size, locate the cube size control in
the front of the control box, and rotate the
adjustment screw one eighth of a turn
COUNTER Clockwise to produce SMALLER sized
ice cubes
Clockwise to produce LARGER ice cubes
Check the size of ice cubes in the next cube
harvest and repeat the adjustment until the correct
ice cube size is achieved.
13. Check Harvest Time. There must be enough
time in harvest to defrost all the cubes, but not an
excessive amount that will waste capacity. The
length of the harvest cycle is determined by the
timer cam positions.
If needed, adjust the harvest time so that there are
about 15 seconds of harvest time left after the last
cube has fallen off the evaporators.
Because harvest time varies with the water and air
temperatures at the ice machine, colder air and
water will result in faster ice making, but longer
harvest cycles. Do not adjust harvest time too
short or the unit will not harvest all the ice.
The harvest time is set by: loosening the set screw
on the cam, rotating the shaft so that the opening
between the cams increases or decreases,
retightening the set screw when the cams are in
the desired position. More of an opening between
the cams = more harvest time.
An adjustment of the cube size control may be
needed after the harvest time has be changed.
Check cube size again.
14. Check Bin Ice Level Control: With the
icemaker in a harvest cycle, place something flat &
solid directly below the sensor socket (located
near the center back of the base). The machine
will then switch OFF at the end of the harvest
cycle. Within seconds after removal of the
obstruction the icemaker will restart.
The control has two postions, FULL and PARTIAL.
Full shuts the machine off when ice is 8" from the
bottom of the sensor socket. The control will not
work on bins taller than 8’.
15. Replace all covers, panels and screws.
16. Fill out and mail in the Warranty Registration
and Customer Response form. Explain to the
owner/user the operation and maintenance
requirements of the ice machine. Inform the owner
of the name and telephone number of the local
SCOTSMAN Distributor or service agency.
JUST RIGHT
TOO SMALL
When the cubes are the correct size, they will be
connected together vertically, and drop off in strips.
The batch weight will be about 13.5 to 14.5 lb.
CUBE SIZE DIAGRAM
Note: If the cubes at the bottom rows of some evaporators
are smaller than others. the size difference does not affect
capacity or performance. However, there should be some
ice in all cells. If not, contact the Factory.
