Initial Start Up
1. Remove front panel. Check machine for any
packing or wires rubbing moving parts. Note
location of control board in upper left corner of the
machine’s front.
2. Switch on the electrical power to the machine.
Observe that some of the control’s indicator lights
glow and its display shows O.
3. Open the water supply valve.
4. Push and release the ON button. The indicator
light will begin to blink F.
The purge valve will open and the water pump will
start. The inlet water valve will open to add water to
the reservoir. After a few seconds the purge valve will
close and the water pump will stop. Water will flow
into the machine until the reservoir is full. The hot gas
valves and harvest assist devices will activate then
the compressor and water pump will start. If its an air
cooled model the fan(s) motors will begin to turn. The
display will show a continuous F. Five seconds later
the hot gas valves will close and the harvest assist
device will return to its standby position. Warm air will
be discharged from air cooled models.
5. Observe the Ready for Harvest indicator light. It
may blink early in the cycle, that is normal. The
control will ignore that signal for the first 6 minutes
of freeze.
6. During the Freeze cycle open and close the
curtains. The SW1 and SW2 lights on the control
board will blink ON when each curtain is opened
and OFF when closed.
7. Note: Moving a curtain during the Freeze cycle
has no affect on the control, but will cause water
to flow into the cube chute.
8. When the ice has frozen enough, the Ready for
Harvest indicator light will be on steady. After it’s
been on steady for a few seconds Harvest will
begin.
9. The display shows an H.
The hot gas valves open, the air cooled fan motors
shut off and the harvest assist mechanisms are
activated. The purge valve opens to drain some water,
when it does the inlet water valve opens to refill the
reservoir. After a few seconds the purge valve closes
but the inlet water valve continues to fill the reservoir.
Harvest continues until the ice is released as a unit
and forces the curtain to open. When both curtains re-
close the controller returns the unit to a freeze cycle.
10. Check the ice harvested for proper bridge
thickness. The ice bridge is factory set at 3/16
inch. If needed, adjust bridge thickness. Do NOT
make it too thin.
11. Determine the water purge setting from the
table below. If desired, change the setting to
accommodate the local water conditions.
12. Return the front panel to its normal position and
secure it to the machine.
13. Instruct the user in the operation of the machine
and its maintenance requirements.
14. Fill out and mail warranty registration form or
register on line at www.scotsman-ice.com.
Typical Ice Making Cycle Times (minutes).
Listed times are for clean machines in proper
installations. Cycle length at start up will be longer
until the system stabilizes.
