Initial Start Up - Scotsman C1448R Manuel D'installation

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. 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. Wait 4 hours for the compressor's crankcase
heater to warm up the oil in the compressor.
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 valves and harvest assist devices will activate
and the liquid line solenoid valve will open, then the
compressor, remote fan motor and water pump will
start. The display will show a continuous F. Five
seconds later the hot gas valves will close and the
harvest assist devices will return to their standby
positions. 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 unit operation.
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
Remote Condenser Models - Installation Manual
it's been on steady for a few seconds Harvest
will begin.
7. The display shows an H.
The hot gas valves open 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 from
each evaporator and forces each curtain to open.
When both curtains have opened and re-closed the
controller returns the unit to a freeze cycle.
8. 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.
9. Determine the water purge setting from the
table on the next page. If desired, change the
setting to accommodate the local water
conditions.
10. Return the panels to their normal positions and
secure them 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.
Typical Ice Making Cycle Times (minutes)
Listed times are for clean machines. Cycle times at
startup will be longer until the system stabilizes.
