Service manual

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; the inlet water
valve will open, and water will flow into the
reservoir..
2. Switch on the electrical power.
3. Remove the front panel.
3. Locate the ICE/OFF/WASH switch,
switch it to WASH.
4. The water pump will begin to pump
water over the evaporators.
5. Allow the reservoir to refill. Normal water level is
1/8" below the high point of the lower curve of the
siphon u-tube.
6. Switch the ICE/OFF/WASH switch to OFF.
7. Check the action of the siphon. The water level
in the reservoir should drop to the bottom curve of
the U-bend (normal water level) in about 2
minutes. If not, check for proper drain tube
connections.
8. Switch the ICE/OFF/WASH switch to ON.
9. On air cooled models the fan motor will begin to
turn, and warm air will be discharged from the
back of the ice machine.
On water cooled models warm water will begin to
flow from the condenser drain.
10. The water temperature in the reservoir will
soon be 32
0
F., and ice should begin to form on the
evaporators.
11. Allow the ice machine to operate for about
15-20 minutes. The ice should be fully formed and
should be harvested within a few minutes.
12. After harvest, check the ice cube size.
Compare a fresh cube to the diagram on the
back of the front panel. If needed, adjust the
cube size by loosening the set screws and moving
the ice thickness probe adjustment plate.
Move the adjustment plate down for smaller
cubes and up down for larger.
For proper operation, the ice thickness should be
set to the 1
11
⁄
16
" diameter.
The machine is designed to harvest cubes of
only the correct thickness.
