INITIAL START UP
Adjust for the correct size if needed: Locate
cube size control knob in the front of the control
box. Rotate this knob one eighth of a turn
Counter clockwise to produce SMALLER sized
ice cubes or
Clockwise to produce LARGER ice cubes
Observe size of the ice cubes in the next ice cube
harvest and adjust again if needed, until the
correct ice cube is achieved.
14. Check Harvest Time.
The harvest time is determined by the gap in the
timer cam. That gap may be adjusted if needed.
The correct harvest time is when there are about
15 seconds of time left in the harvest cycle after
the last cube has fallen from the evaporators. See
the next page for detailed adjustment instructions.
Do not adjust harvest time TOO SHORT or the
machine will not harvest all the ice.
15. Check ICE BIN LEVEL CONTROL
The amount of ice maintained in the bin is
adjustable. The normal setting is "full". If the
operator desires, the level of ice in the bin may be
adjusted lower to shut off the machine when the
bin is only partially full. The ice bin level control is
designed for the MDB550 ice storage bin, use of
other bins may result in ice levels that are more or
less than the settings on the control indicate.
To Test The Ice Level Setting:
1. Open the bin door and locate on the bottom of
the ice machine, the ice level sensor. It's in a
socket about 2" in diameter and located left of the
evaporator plates.
2. When the machine is running, wait untIl near the
end of a "harvest" cycle.
3. Hold a flat object about the size of this service
manual over the ice level sensor socket.
4. The ice machine should turn off at the end of the
harvest cycle.
5. Slowly lower the flat object straight down.
6. The ice machine will start again at the point
where it will maintain the ice level.
Adjust Bin Ice Level
1. Locate ice level control switch.
2. Move switch to the desired position.

3. To test, wait until the ice machine is near the
end of a "harvest" cycle, if there is ice in the bin
higher than the position the ice level control is set
for, the ice machine will turn OFF at the end of the
harvest cycle. If no ice in the bin, test again as
described under, "To Test The Ice Level Setting".
16. Replace all panels & covers.
17. Fill out and mail in the Customer Evaluation
and Warranty Registration form. Inform the user
how to call for service and the maintinance
requirements of the machine.
