V PRINCIPLES OF POPCORN MACHINE OPERATION

Theory and Observations of Popcorn Machine Operation

1. The efficient production of popcorn requires the presence of popcorn kernels, heat,
and oil. The purpose of the oil is to distribute the heat throughout kernels evenly
and quickly. If the heat is not distributed evenly and quickly, the kernels may burn
instead of pop.

2. In order to pop corn in oil, the kettle, oil and parts near the heating elements are
necessarily and unavoidably heated to temperatures high enough to pop popcorn.
The temperature is controlled using a thermostat located inside the kettle to
maintain the kettle at an operating temperature of approximately:

7700-SC/E/SC-E

For 120/208-240V and 100/200
For 230V and 400V

Contact with these surfaces will burn and scald you. Do not touch the kettle, oil or
parts in the direct vicinity of the heating elements.

3. The kettle is provided with an agitator to assist in the quick and even distribution of

heat throughout the kernels.

4. The oil is heated to high temperatures in a kettle provided with electric heating
elements to reach proper popping temperature. An operator is required in the
vicinity of the kettle only when handling corn or dumping popped corn from the
kettle. Neither of these operations requires direct contact with the kettle. Direct
contact with the hot oil, kettle, or heating elements could result in serious burns or
scalds. Keep away from the kettle whenever possible. Use the handle when
dumping the kettle, and use the provided cups when necessary to measure corn,
oil and salt.

5. As the popcorn pops, it will push the lid open and discharge into the cabinet. When
the corn finishes popping, the corn remaining in the kettle can be removed by
holding the kettle handle in your right hand and rotating down in a clockwise
direction to dump the kettle.

420°F (215°C) for salt and 385°F (196°C) for sugar

6. Your 7700 model Cretors oil pump, which when properly adjusted, automatically
delivers the proper amount of oil to the popping kettle.

7. A Cretors Hot rod is available to assist in the melting of solidified oil.

VII INSTALLATION INSTRUCTIONS

A. Location

Choose a location for your Cretors oil pump to maximize the ease of operation and
maintenance procedures. Check your local building and fire codes for location restrictions.

contained unit

B. Power Supply

Determine the required power supply.

Connect your dispenser only to the correct power source. Failure to do so may result
in personal injury or death and may damage your machine.

C. Cretors & Co. recommends dedicated circuits for popcorn machines. The 7700-SC
model pump requires a 15 amp circuit. Check your local electrical codes regarding
cut-off requirements.

Make certain your popcorn machine and oil pump is properly grounded. Failure to do
so may result in damage to your equipment or present a shock hazard.

C. Connecting oil pump to power source

Make certain that power supply circuit breakers are in the off position. Make certain
all switches on the machine are in the off position before plugging in your 7700 model
Cretors oil pumps.

Perform work only on de-energized circuits. Failure to do so may lead to electrical
shock resulting in personal injury or death.

7700-SC/E/SC-E

D.

Plug your machine and oil pump into the correct type of outlet, turn on the circuit breaker

and then turn on the machine switches. If the motor groans, the receptacle in the 8 108 485
115 been improperly wired. Contact an Electrician.

Make certain all switches are in the off position before plugging in your Cretors popcorn machine
and oil pump.

E. Pump Installation

Cretors oil pump and Hot Rod are intended for use in standard steel pails only. The
following instructions assume the presence of a Deluxe or Economy base.

1. Make certain the pump switch on the control panel is in the OFF position.

2. Inserting the pump into the pail
a. Place the pump on top of the oil and center in the pail. If the oil is solid, the pump

can be rotated clockwise/counterclockwise 90°, and the metal “blade” on the bottom
of the pump will cut into the hard oil. Connect the power supply cord to the pump.
The special connector will only plug in one way and it may be necessary to rotate it
in order to insert it completely.

Turn on the auxiliary and pump switches and set the time heat switch to 20 or 30

minutes and allow the pump to melt itself into the oil. Proceed to step 3.

Do not overheat the oil in the pail. Once the oil is liquefied, it is not necessary to
continue heating the oil. If the heat timer is continually restarted, the oil will become
too hot and damage the oil tubing, becoming a source of leaks, and the hot pail a
source of burns.

If any oil should spill or leak, be sure to promptly and thoroughly clean the exposed
area. Failure to do so may result in a slipping hazard resulting in serious injury or
death.

3. Connect the pump to the oil delivery tube by pushing the quick connect socket at the
end of the delivery hose, onto the quick disconnect plug mounted on the support cover.
When the plug is fully inserted, the spring will snap into place and hold the connector
securely.

4. Make certain the oil delivery hose contains no low spots. Oil may solidify in such low
spots and clog the hose.

F. Pump Adjustment

Make sure that the popper heat switch is off during pump adjustments. This is to
avoid touching a hot kettle, which may result in serious burns.

1. To check the output adjustment, place the kettle in the dump position and hold the oil
measure cup under the oil delivery tube.

7700-SC/E/SC-E

Never hold the oil measure cup under the oil delivery tube if the kettle is hot. This
may result in serious burns or injuries.

2. Press the delivery button and wait for the pump to cycle. Dispose of the oil, and cycle
the pump again. To obtain accurate readings, let the oil drain back to the pail as it
would between popping. Observe the oil in the tube to confirm that the oil has drained
back to the pail.

3. After three cycles, the amount of delivered will be consistent. Check this amount with
the measuring cup.

*Recommended pump timer settings. Machines may differ slightly.

4. If the amount of oil is not correct, it may be adjusted. To adjust the pump:

a. Turn off the pump switch
b. Put the pail step in place
c. Disconnect oil hose
d. Move pail out of cabinet onto pail step. (Use a slight lifting and pulling motion)

Make sure you brace the pail step against the cabinet to avoid sliding it off the base of
the cabinet when pulling the pail across it. Use proper moving techniques to avoid
injury to back.

e. To set the oil quantity delivery:

• Remove the snap out plug on top of the switch box, which is on the top of the
pump, to expose the timer.

• Check to make sure the timer has good contact by pushing down lightly on
timer, making certain not to push any of the switches.

• Switches 1 through 10 are each assigned a certain amount of seconds of delay
time. Each successive switch is double the amount of delay time for the switch
before it. The amounts of delay time are written at the top, along the
“OPEN”/”OFF” line (i.e. 1,2,4,8, etc).

• The switch must be in the UP position along the “OPEN”/”OFF” line for the
delay time to apply. An example of this for three seconds would have the switch
corresponding to the 1 on the “OPEN”/”OFF” line up along with the switch
corresponding to the 2 on the “OPEN”/”OFF” line.

f. Install snap out plug (which was removed in first step in section e).

Move pail back into cabinet. Use proper moving techniques to avoid injury to back.

g. Connect oil hose by snapping in place.
h. Remove pail step and place in bottom of cabinet for easy access in future.
i. Turn on the pump switch and re-check the oil output using steps 1thru 4 in the

Pump Adjustment section.

3. Measuring instruments have been provided to accurately measure the proper amounts
of popcorn, salt and oil. The correct amount for each popping is stated in the machine
manual. As a general rule: use three (3) parts corn to one (1) part oil for correct
popping.

Close the lid on the kettle. Avoid contact with the kettle. Contact with a hot popping
kettle may result in serious burns or scalds.

4. Push the oil pump button which will provide the correct amount of oil based on
previously setting and testing the timer.

5. As the corn pops, it will push the lid open, allowing the corn to discharge from the
kettle. When the corn finishes popping, dump the popper pan.

Avoid contact with kettle when dumping popped corn. Failure to do so may result in
serious burns or scalds.

6. When the oil bucket is empty, insert the oil pump into a new bucket as described in the
Installation Section.

X SANITATION INSTRUCTIONS

7700-SC/E/SC-E

Be certain the machine is turned ‘OFF’ and power is unplugged before sanitizing this
machine unless a specific cleaning procedure requires power to the machine. Failure
to do so could result in injury or death.

Do not clean heated surfaces until they have been given sufficient time to cool. Failure
to do so may result in serious burns or scalds.

The pump is most easily cleaned by using two empty popping oil pails or buckets that
have been thoroughly cleaned of oil. The cleaning procedure is:

1. Fill one pail ½ full of hot water and mix in ½ package of CKC (Cretors Kettle

Cleaner).

2. Put the pump on the pail and turn on the heat timer to 20 minutes and leave until

the water is hot.

3. Unplug the pump and hold the pump over the pail. Clean the outside of the pump

and heating element. Do not immerse the pump motor or get the top plate and
motor wet. Put the pump on the pail again, and reconnect the electrical power
supply and oil line.

4. Put the kettle in the dump position, and place a container under the oil discharge

tube to catch the cleaning water.

5. Cycle the pump several times catching the cleaning water in the empty container.

6. Disconnect the pump. Take the pump to a sink and thoroughly rinse the pump and

heat element.
