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.

it’s been on steady for a few seconds Harvest will begin.

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.

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

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

	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.
