Initial Start Up

1. Remove the front panel by removing the two
screws holding it to the cabinet and pulling the
panel down and off the machine.
2. Turn on the water supply, correct any leaks.
Note: Water supply MUST be turned on first to
allow water to enter the machine properly.
3. Locate the On/Off/Wash master switch.
4. Move the switch to the On position.
5. Ice bridge thickness and harvest time indicator
lights will switch on. They will not change unless
the cube size or harvest times are manually
adjusted. The timer light will also be on.
6. The unit begins to fill the reservoir with water.
Two streams of water can be seen behind the
curtain. The compressor and hot gas valve will be
energized, but the fan motor and pump will be off.
After a time the water will have filled the reservoir
but will continue to fill and excess water will drain
from the machine. This is normal and helps the
machine from forming excessive mineral scale.
7. After 2 minutes the water and hot gas valves will
close and the pump and fan motors will start. A
blue light in the control panel will glow indicating
the beginning of the freeze cycle.
8. Warm air will begin to blow out the left front of the
machine and water will spray up at the inverted
ice making mold. It is normal for a small amount of
water to drip from the ice making area.
When the water temperature reaches a pre-set point
the water pump will stop for about 30 seconds then
resume.
Freezing then continues for many minutes until the
temperature of the refrigeration system drops to a
set point, indicated by a yellow light glowing on the
control panel. In colder rooms the fan motor may
turn on and off. After the yellow light switches on the
freeze cycle continues for seven more minutes. At that
time the unit changes to the ice release or harvest
cycle. During the ice harvest the hot gas valve and
inlet water valve are open, while the pump and fan
motors will stop. The blue and yellow lights will go out.
Water will refill the reservoir.

9. Within a minute or so the ice formed in the mold
will fall down and slide into the ice storage bin.
The ice will release as a group so all of the ice
formed will fall at once and the next freeze cycle
will begin in a few seconds. The timer light may
switch on at the end of the harvest cycle.
10. Check the thickness of the ice connecting the
cubes to each other, that connection is known as
a bridge and it should be about 1/8 inch or 3 to 4
mm thick. It is preset from the factory and should
be satisfactory.
Adjustments:
If the ice bridge is too big or too small, the thickness
may be adjusted.
Note: The bridge thickness adjustment is used
to obtain the CORRECT size, not to adjust to
individual preferences. Do NOT make the ice
bridge too thick or too thin, as either will reduce
ice making capacity. Do NOT attempt to adjust the
machine to release individual cubes. There is only
ONE correct size.
11. Ice making will continue until the ice level reaches
the metal tube in the storage bin, when ice
contacts that tube the machine will stop making
ice. This can occur in any part of any cycle.
12. Removing ice from the ice storage bin will restart
the ice making process.
13. Check for and correct any water leaks from the
unit or drain system.
14. Return the front panel to its normal position and
secure it to the cabinet with the original screws.
