V. PURPOSE OF MANUAL
This instruction manual is intended to familiarize owners with the servicing
and safety procedures associated with your Cretors machine.
This manual should be kept available to maintenance personnel.
VI. INSTALLATION INSTRUCTIONS
A. Location
Choose a location for your Cretors machine that maximizes the ease of operation and
maintenance procedures. Be sure to check your local building and fire codes for location
restrictions.
B. Power Supply
1. The 7900 Oil Pump is provided with either 120 volt components, which requires a 120
volt circuit for proper operation or 230V components. Check the nameplate to
determine the required power supply.
Connect your popcorn machine and oil pump only to the correct power source. Failure
to do so may result in personal injury or death and may damage your popper.
2. C. Cretors and Company recommends dedicated circuits for the 7900 Model Cretors Oil
Pump. The 7900 Model Cretors Oil Pump requires a dedicated circuit to avoid a voltage
drop in the supply wiring. Check your local electrical codes regarding fuse or circuit
breaker requirements.
Make certain your machine is properly grounded. Failure to do so may result in
damage to your equipment or present a shock hazard.
C. Connecting Oil Pump to the Power Supply
1. Make certain that the power supply circuit breakers are in the off position.
Perform work only on de-energized circuits. Failure to do so may result in damage to
your equipment or present a shock hazard.
2. Make certain all switches on the popcorn machine are in the off position before
plugging in your 7900 Model Cretors Oil Pump.
3. Plug your popcorn 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 wall may have been improperly wired. Contact an electrician.
D. Pump Installation

7900MANUAL REV-A
7 | P a g e
1. Make certain the pump switch on the control panel is in the off position.
2. Receiving a 7900 pump as a replacement for 7700 or earlier models.
a. The units equipped with wood bases, remove the (2) screws on back flange of oil pail
tray (P/N 1349) and remove tray. This tray is not needed for 7900 model.
b. Replace existing plastic hose (#1223) (7” on Diplomat, 19” on President) with 20” or
24” plastic hose respectively. The existing hose clamps (#1609) and socket (#5216)
are still used. If existing hose length was shortened so the socket (#5216) does not
have sufficient length to connect to the plug (#5217) on the pump, replace the entire
length –110” (for Merchant and Profiteer).
Use proper lifting techniques when removing the pump assembly to avoid injury to
back.
3. The 7900 model weighs approximately 30 lbs., so use proper lifting techniques and slide
pump into cabinet. Allow at least 3” from the front edge of pump to the back side of
door. This will ensure that the door, when closed, will not interfere with the properly
connected bag connector.
4. Connect hose (#1223) simply by pushing socket (#5216) into plug (#5217) and make
sure that it has snapped into place. Test engagement by pulling up on the hose near
connection, fittings will not disengage.
5. Connect pump cord and plug to pump receptacle located on the top or on the back of
the model 7900 pump.
6. While using proper lifting techniques, load one box into bottom tray and one on top.
Following the instructions on the box itself, connect the bag connector to the Bag-N-Box
nozzle. You are now ready to adjust the pump as outlined in Pump Adjustment.
Make sure that the popper heat switch is in the off position during all pump
adjustments. Failure to do so may result in serious burns.
WARNING! If either shelf is not occupied by the Bag-N-Box oil, use caution around
these surfaces as they will be hot! Failure to do so may result in serious burns.
E. Pump Adjustment
1. Make sure that the pump power switch and the auxiliary switch located on the popper are
on.
2. Check the output of the pump by placing the kettle in the dumped position and hold the
oil measuring cup under the oil delivery tube. With the pedestal mounted units (i.e.
Giant/President), disconnect the oil tube from the kettle and dispense the oil into the
measuring cup.

7900MANUAL REV-A
8 | P a g e
WARNING! Never hold the oil measuring cup under the oil delivery tube if the kettle
is in the up position. The kettle maybe hot! Failure to do so may result in serious
burns.
3. Press the delivery button or One Pop button and wait for the pump to cycle. Dispose of
the oil, and cycle the pump again.
4. After three cycles, the amount of oil delivered will be consistent. Check this amount with
the measuring cup.
5. If the amount of oil is not correct, it may be adjusted. For a Salt/Sugar machine, the timer is
located in the popper. To adjust the pump:
a. Turn off the pump switch.
b. To set the amount of oil being delivered:
i) Remove the snap out plug on the front side of the bottom cover to expose the timer.
ii) Check to make sure the timer has good contact by pushing down lightly onto the
timer base, making certain not to push any of the switches.
iii) Switches 1 through 10 are each assigned a certain amount of seconds of run time.
Each successive switch doubles the run time for the switch before it. The amount of
run time is written at the top, along the Open/Off line (i.e. 1,2,4,8, etc.)
iv) The switch must be in the Up position along the Open/Off line for the run time to
apply. For example, to make the pump run for three seconds, the timer would have
the switch corresponding to 1 on the Open/Off line up along with the switch
corresponding to 2 on the Open/Off line.
To turn the dip switches ON the dip switch needs to be pressed down to the
number side opposite of the open side. Open is off.
Switch #1
= 1 seconds
#2
= 2 seconds
#3
= 4 seconds
#4
= 8 seconds
#5
= 16 seconds
Example: If you turn #3 and #4 on, the time delay will be 12 seconds.

EG60 20 oz. 16 seconds
c. Turn on the pump switch and re-check the oil output using steps 1-5 in the Pump
Adjustment Section.
d. Install snap out plug.
F. Bag-N-Box Connector
1. Prepare the box for use by breaking the perforated opening on the box and bending back
the corrugated tab. Reach inside and grasp the bag spout. Place the ring of the spout into
the box slot and lock it into place with the corrugated tab.
a. Place the Bag-N-Box in the appropriate shelves. Next remove the travel cap from the
spout. The travel cap prevents the dirt and dust from coming in contact with the
internal slider for sanitary hook-up.
b. Snap the locking plate over the bag spout. The tapered probe on the connector is then
pushed into the bag spout and it locks into place. This bi-directional locking action does
two things. One, it eliminates any possibility of accidental disconnect, giving the user a
“fool proof” positive connection and two, it opens the channel allowing product to
follow.
c. When the Bag-N-Box container is empty, disengage the connector by snapping the
connector probe into the out position and remove it from the bag spout. This
disconnects and reseals the bag. All product contact surfaces are protected ensuring a
sanitary situation.
d. Repeat steps a-c to properly re-connect Bag-N-Box to the pump.
NOTE: Prior to each attachment of the Bag-N-Box connector, ensure that the probe has not
been contaminated. If this has occurred, clean the connector as described in the Sanitation
Instructions.
VIII. OPERATING INSTRUCTIONS
Do not attempt to operate your Cretors popcorn machine or oil pump until you have
read and understood this manual. Failure to do so may result in serious injury or
death.

cause oil to stain the kettle, possibly resulting in an unsanitary condition. It may also
cause a “flash” fire if oil is added to a kettle left unattended with the heat on, resulting
in serious burns or death.
A. Operate only after “Installation Instructions” in the Service Manual have been followed.
B. To operate your Cretors 7900 oil pump:
1. Turn on the pump switch, located on the popper, to the on position.
2. Pre-heat the popping oil until liquid, if necessary.
3. Push the oil pump or the One-Pop button to dispense oil. If too much or too little oil is
being dispensed, see “Pump Adjustment” in the Service Manual.
4. Exchange boxes by disconnecting bag connector from bottom and connecting to top.
5. Follow the recommended sanitation procedures.
IX. SANITATION INSTRUCTIONS
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.

7900MANUAL REV-A

The 7900 pump is designed as a closed system and should remain aseptic.
If you believe your pump system is contaminated, then you will need to clean the system.
The pump is cleaned using the following steps:
1. Remove the Bag-N-Box connector.
2. Place the end of the oil tube into hot soapy water in a pail.
3. Cycle pump sufficiently to flush system. Be sure to have a container to catch the water at
the discharge tube near the kettle.
4. Move the oil tube to clean hot water and cycle pump to flush hot soapy water from the
system.
5. IMPORTANT: When system is clean, you must then cycle the system with oil to prevent
any damage to the pump. Never leave the pump wet with water only. Mineral oil may
be used.
To Clean Bag-N-Box Connector:
1. Remove from tubing.
2. Remove probe body from clamp by spreading clamp body tabs and sliding probe body out.
3. Remove probe spout adapter from probe body by unscrewing stem from probe body.
4. Remove seal body and spring from stem and nut assembly by unsnapping seal body from
stem.
5. Clean all parts in accordance to NSF and local requirements (hot, soapy water, and rinse).
Do not use petroleum base cleaning agents or abrasive cleaners. Damage to sealing surfaces
may occur and jeopardize the sanitary integrity of the connector.
6. Inspect the three “O” rings for damage or imbedded particles. Replace as required.
7. Reassemble by reversing steps 1-4.
Sanitation of your popcorn machine and oil pump is imperative for production of an appetizing
product. Failure to follow proper sanitation procedures for food contact surfaces or usage of
contaminated ingredients (salt, oil, seasonings) could result in poor product quality and may cause
illness to your customers.
Your Cretors oil pump is National Sanitation Foundation (NSF) listed, and can be easily
cleaned to assure a high quality product. Use pure ingredients, always emphasize machine
sanitation, and follow the sanitation procedures outlined in this manual to protect the
welfare of your customers.
