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 Remove tape securing each curtain to its
evaporator.
3 Switch on the electrical power to the machine.
Observe that some of the control’s indicator
lights glow and its display shows O.
4 Open the water supply valve.
5 Push and release the ON button. The indicator
light will begin to blink F.
The flush 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 flush 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.
6 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.
7 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.
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 flush valve opens to drain some
water, when it does the inlet water valve opens to
refill the reservoir. After a few seconds the flush
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 flush 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.
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.
