How the ICE Machine Works
A general description of how the ICE-O-Matic Flaker works is given below:
Whenever the ON/OFF switch is in the ON position (and the bin control and safety controls are closed) the machine
will continuously make ice and deliver it into the storage bin.
Water enters a reservoir through the float valve and is gravity fed into the evaporator barrel through an opening in the
bottom of the barrel. Water fills the evaporator to the same level as the water in the reservoir. This level is maintained
by a float valve which stops the flow of water into the reservoir when the reservoir becomes full.
When the ON/OFF switch is turned to the ON position, the auger motor energizes. On larger machines the
compressor is delayed for 2 to 4 minutes. After the compressor delay period, the compressor and condenser fan
motor (air cooled machines only) starts causing the temperature of the evaporator to drop.
The water in the evaporator freezes to the inner wall of the evaporator barrel. A belt driven gear reducer continuously
turns the auger inside the evaporator. As the auger turns, it pushes the ice off of the barrel wall. The auger also
drives the flakes of ice upward and forces them out of the window in the barrel, through the delivery chute and into the
storage bin. As ice is pushed out through the evaporator, make-up water enters the bottom of the evaporator.
As the level of ice in the bin rises,
the ice will contact the
thermostatic bin control thermal
well. The bin control then opens,
shutting the machine off until ice
is removed, allowing the bin
control to once again close,
starting the machine.

Start-Up Procedure
Please Follow These Instructions Carefully
● Check the auger assembly to insure that it turns freely. Turning the
large pulley of the gear reducer should require only slight finger
pressure.
●Check that the condenser fan turns freely.
●Remove tape and packing from the float valve and reservoir
●Before turning the water supply on, check the low temperature safety
control for proper operation:
Turn the machine ON. There may be a compressor delay of 2
to 4 minutes. Allow the machine to operate for 3 to 7 minutes
after the compressor energizes. The safety control should
open and shut down the ice machine within this time period.
If the control does not open, rotate the adjustment screw
counter-clockwise until the control opens.
The safety control is located in the electrical control box and
the capillary tube is in the thermal well at the bottom of the
evaporator.
The Safety Control turns the machine off if the
evaporator temperature reaches approximately
30ْ F (-1C). The Safety Control can be adjusted by
turning the adjusting screw clockwise to lower the
cut-out temperature (colder) or counterclockwise to
raise the cut-out temperature (warmer).
● Check the water level in the water reservoir.
Turn the water to the ice machine on. If this is a water cooled
unit, insure that the water cooled condenser has an adequate
water supply.
Turn the ON/Off switch ON, with the machine running and
making ice, the water level in the reservoir should be even
with the top of the insulation around the evaporator barrel.
Water
Level
If the water level is too low or too high, the water level may be
adjusted lower or higher by adjusting the float mounting
bracket.
Loosen or remove the two (2) screws securing the float
bracket to the frame.
Raise or lower the float bracket so that the water level is even
with the top of the insulation surrounding the evaporator.
Resecure the float bracket by tightening the screws.

EF and EMF Series
Start-Up Procedure
●Check bin control for proper operation
The bin control is used to shut the machine off when the bin fills with ice. The bin control must be checked upon
installation or initial start-up and when performing maintenance. Adjustments are not covered under warranty.
With the machine running and making ice, hold ice against the brass thermal well that houses the bin control capillary
tube. The brass thermal well is located on the inside of the down chute on the EMF models and in the storage bin on
the EF models. The machine should shut off in approximately 2 minutes. Remove the ice from the thermal well and
the machine should come back on within 2 minutes. The bin control adjusting screw can be accessed through a hole
in the control box. Note: On some models there will be a compressor delay of 2 to 4 minutes after turning the machine
on.
If ice is touching the bin control thermal well for more
than 3 minutes and the machine has not shut off, turn
the adjusting screw counter-clockwise approximately
1/8 turn and recheck.
●Check secondary bin control for proper operation
EF Series Flakers: With the machine off, reach inside the bin and push up on the white diaphragm located at the top of
the bin. The switch contacts should change before the diaphragm is lifted ½ inch. Contacts should change again
when the diaphragm is
released. To adjust switch,
remove cabinet top and
move switch to proper
position.
EMF Series Flakers: With the machine off, lift up slightly on the
white diaphragm located on top of the down chute. The switch
contacts should change before the actuator is lifted more than ½
inch. Contacts should change again when the diaphragm is
released. To adjust switch, remove cabinet top and move
switch to proper position.
●Check for water leaks and excessive noise.

Cabinet Care
Cleaning stainless steel
Commercial grades of stainless steel are susceptible to rusting if not properly maintained. It is important that you
properly care for the stainless steel surfaces of your ice machine and bin to avoid the possibility of rust or corrosion.
Use the following recommended guidelines for keeping your stainless steel looking like new:
1. Clean the stainless steel thoroughly once a week. Clean frequently to avoid build-up of hard, stubborn stains.
Also, hard water stains left to sit can weaken the steel's corrosion resistance and lead to rust. Use a nonabrasive
cloth or sponge, working with, not across, the grain.
2. Don't use abrasive tools to clean the steel surface. Do not use steel wool, abrasive sponge pads, wire brushes
or scrapers to clean the steel. Such tools can break through the "passivation" layer - the thin layer on the surface
of stainless steel that protects it from corrosion.
3. Don't use cleaners that use chlorine or chlorides. Don't use chlorine bleach or products like Comet to clean the
steel. Chlorides break down the passivation layer and can cause rusting.
4. Rinse with clean water. If chlorinated cleansers are used, you must thoroughly rinse the surface with clean water
and wipe dry immediately.
5. Use the right cleaning agent. The table below lists the recommended cleaning agents for common stainless steel
cleaning problems:
Cleaning Activity
Cleaning Agent
Method of Application
Routine cleaning
Soap, Ammonia, Windex, or
detergent with water.
Fantastik, 409 Spic’nSpan
Liquid are also approve for
Stainless Steel.
Apply with a clean cloth
or sponge. Rinse with
clean water and wipe dry.
Removing grease or
fatty acids
Easy-Off or similar oven
cleaners.
Apply generously, allow
to stand for 15-20 minutes.
Rinse with clean water.
Repeat as required.
