Initial Start Up
1. Remove front and left side panels. 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. Wait 4 hours for the compressor’s crankcase
heater to warm up the oil in the compressor.
Start Up
1. Open the water supply valve.
2. Turn the receiver’s outlet valve to the full open
position.
3. 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 valve
and harvest assist device will activate and the liquid
line solenoid valve will open, then the compressor
and water pump will start. 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 the
condenser coil.
4. 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 cube chute.
5. Observe the Ready for Harvest indicator light. It
may blink early in the freeze cycle, that is normal.
The control will ignore that signal for the first 6
minutes of freeze.
6. 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.
7. The display shows an H.
The hot gas valve opens and the harvest assist
mechanism is 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 the curtain opens it signals the controller which
returns the unit to a freeze cycle.
8. 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.
9. Return the panels to their normal positions and
secure them to the machine.
10. Instruct the user in the operation of the machine
and its maintenance requirements.
11. Fill out and mail the warranty registration form.
Typical Cycle Times (minutes)
Listed times are for clean machines. Cycle times at
startup will be longer until the system stabilizes.
