Initial Start Up

1. Remove left front louver. Check machine for
any packing or wires rubbing moving parts.
Note location of control board at the left.
2. Switch the on off
switch to On.
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 code display will
begin to blink F. Be sure front On/Off switch is
in the ON position.
The purge valve opens and the water pump starts.
In a few seconds the purge valve closes and the
water pump stops. Water will flow into the machine
until the reservoir is full. The hot gas valve and
harvest assist device will activate, then the
compressor and water pump will start. If it's an air
cooled model the fan(s) motors will begin to turn a
few moments after the compressor starts. The
display will show a continuous F. Five seconds later
the hot gas valve 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 move the curtain and
observe that the SW1 or SW2 light on the
control board blinks On when the curtain
moves away from the evaporator and Off when
returned to its normal position.
Note: Moving the curtain during the Freeze cycle
has no affect on control function, but will cause
water to flow into the bin.
8. When enough ice has frozen, the Ready for
Harvest indicator light will be on steady. After

it's been on steady for a few seconds Harvest
will begin.
The display shows an H. The hot gas valve opens,
the air cooled fan motor(s) shut off and the harvest
assist mechanism is activated. The purge valve
opens to drain some water, when it does the float
valve opens to refill the reservoir. After a few
seconds the purge valve closes but the float valve
continues to fill the reservoir. Harvest continues
until the ice is released as a unit and forces the
curtain to open. When the curtain opens it signals
the controller which returns the unit to a freeze
cycle.
9. Check the ice harvested for proper bridge
thickness. The ice bridge is factory set at 1/8
inch. If needed, adjust bridge thickness. Do
NOT make it too thin.
10. Return the louver to its normal position and
secure it to the machine.
11. Instruct the user in the operation of the
machine and its maintenance requirements.
12. Fill out and mail the warranty registration form.
