Initial Start Up
After the final check list has been gone through,
the ice machine may be started up.
1. Open the water shut off valve.
2. Switch on the electrical power.
2. Remove the front panel.
4. Remove the control box cover.
5. Locate the timer and
rotate the cam clockwise
until the timer is in the
Harvest Position.
6. Switch the compressor
switch to OFF.
3. Locate the ON/OFF
switch, switch it to ON.
4. The inlet water valve will
open, and water will flow
into the reservoir. The
water pump will begin to
pump water over the
evaporators.
5. Allow the reservoir to fill.
6. Switch the compressor
switch to ON.
7. On air cooled models the fan motor will begin to
turn, and warm air will be discharged from the left
side of the ice machine. On water cooled models
warm water will begin to flow from the condenser
drain.
Note: To optimize the balance between ice
production and water use, the water cooled
discharge pressure must be 245 P.S.I.G. Check
discharge pressure and adjust water regulating
valve to obtain 245 P.S.I.G. discharge pressure.
8. The water temperature in the reservoir will soon
be 32
0
F., and ice should begin to form on the
evaporators. Note: In some cases some slush will
form in the reservoir. This is temporary and normal.
9. Allow the ice machine to operate for about 20
minutes. The ice should be fully formed and should
be harvested within a few minutes.
10. After harvest, check the ice cube size. If
needed, adjust the cube size by rotating the
adjustment knob of the cube size control. Rotate it
1/8 turn clockwise to make the cubes thicker, and
rotate it 1/8 turn counterclockwise to make the
cubes thinner.
The machine is designed to only harvest
cubes that are the correct thickness.
