OPERATING INSTRUCTIONS(Pg. 4-5)
NOTE: When connecting the bag-in-box system,
and (2) two bag connectors, (Daisy-chained) you
must be sure to connect the bag connectors as
shown in the picture to the left.
OPERATION
Turn the Oil System Master switch, located on the popcorn machine, to the ON position. This will start
the heater/blower that will maintain cabinet temperature and provide power for the pump.
Pressing the red Oil Dispense button located on the popcorn machine will dispense the oil into the kettle.
If this is the first time the unit has been used, it may take a minute to completely fill the tube and dispense
oil.
BEFORE SETTING THE OIL DISPENSE TIME
First be sure the lines have been primed with oil up to the point of discharge, removing all air from the
lines. This insures an accurate oil measure with each batch.
E-Z SET TIMER OPERATION
This machine is equipped with a programmable timer for setting the amount of oil needed for popping
popcorn. Holding the red Oil Dispense push button down while turning on the Oil System Master switch;
while continuing to hold the red oil dispense button for five seconds puts the unit in the program mode.
The oil system master switch light will start to blink off and on indicating that the timer is in the program
mode. Hold a cup under the oil line and then use the manual mode of operation to prime the oil line. After
priming the oil line, use a measuring cup and the automatic mode of operation to set the correct oil
amount.
The Dead-leg connector
(With only one hose
connected to it) must be
installed on the top box.
The Pass-thru connector
(With two hoses
connected to it) must be
installed on the bottom
box.

OPERATING INSTRUCTIONS(Continued)
AUTOMATIC OPERATION
When in the program mode press and release the oil Dispense switch to start the oil flowing. When the
correct amount of oil has been dispensed into the measuring cup (P.N. 62807) push the oil Dispense
switch to stop the oil flow. The oil amount can be “topped off” by pushing the oil Dispense switch on/off
as many times as needed to finalize the oil amount. Turning the Oil System Master switch off and then
back on puts the unit in the regular mode. The unit will now dispense the “programmed” amount of oil
when the oil Dispense switch is pushed. The oil light will light only when the oil pump is on.
MANUAL OPERATION
When in the program mode, immediately turn off the Oil System Master switch; turning the Oil System
Master back on puts the timer in the manual mode of operation. The unit will now dispense oil only while
the oil Dispense switch is pushed.
NOTES:
Model 2257D has the capability of “remembering” two different settings for poppers with the
“Salt/Sweet” option or “Flexi-Pop option.
For Salt/Sweet models, just put the switch in the “salt” position, and set the oil amount as described
above. Then put the switch in the “sweet” position and repeat the setting procedure. The pump will
remember both settings.
For Flexi-Pop models, just put the “Load” switch in one position, 32oz. for example, and then set the oil
amount. Then put the load switch in the other position, 18oz. for example. And repeat the setting
procedure.
Model 2457S is the heated line option for the 2257 pump.

Preventing and Troubleshooting Oil Delivery Issues
It may occur at times that the Bag-In-Box oil pumping system does not deliver oil to the kettle, or delivers
it in incorrect amounts. This section is intended to list the most common causes of these problems, and
the procedures necessary to prevent and, if necessary, correct them.
Oil Temperature
Coconut oil becomes a solid at temperatures above the average room temperature.
For this reason, it is necessary to ensure that the oil has been permitted to come to working temperature
before attempting to pump it through the system. If the machine has not been used for several days, the
oil master switch should be turned on the night before it is expected that the machine will be used. For
machines which are in daily use, even if not round the clock, leave the oil master switch on at all times
and keep the base cabinet doors closed to prevent the oil from becoming solid.
Bag-In-Box Mounting
Because the bag’s dispensing connector is offset toward the bottom of the box, to permit free oil flow and
complete emptying of the oil from the bag, the box should never be mounted upside down. Most boxes
supplied will be clearly marked as to which side should be up during dispensing. (Note that in some cases
the box is intended to be stored with one side up, but to be turned and used in dispensing with the other
side up.) Be sure to double check to ensure that the box is mounted in the correct dispensing orientation.
You may encounter boxes with no clear markings to indicate dispensing orientation. A reliable guide in
this case (and also for those boxes which are marked), is the direction that the top side flap of the
corrugated box is folded. When the box is properly mounted for dispensing, the top side flap will fold
down from the top edge of the box, so that if one were to attempt to separate the flap it would be
necessary to pull up from the bottom edge. See the illustrations below.

Bag and Hose Connector Issues (Pg. 7-9)
There are two different types of dispensing nozzles employed on the Bag-In-Box oils, as well as two
different types of connectors installed on the oil pumping system hoses which connect to the bag’s
dispensing nozzles. The particular combination of connectors in your system will determine the
appropriate method for connecting the Bag-In-Box oil bag to the system hosing. These combinations will
be illustrated and explained in the following section
Bag Dispensing Nozzle (Blue Insert)
1. With the blue collar on the hose connector retracted toward
crosspiece, slide hose connector shell onto bag nozzle.
2. Holding the bag nozzle behind the flange, slide the blue collar
forward to lock the hose connector onto the bag nozzle.
3. Connector shown with shell correctly engaged and collar
forward in lock position.
4. Place fingers behind flange and use thumbs to slide the
crosspiece forward into the nozzle. Oil flow is initiated.

Bag and Hose Connector Issues (Continued)
White Insert Bag Nozzle with Blue/White Hose Connector
1. With the blue collar on the hose connector retracted toward crosspiece,
slide hose connector shell onto bag nozzle
2. Holding the bag connector, slide the blue collar forward to lock the hose
connector onto the bag nozzle.
3. Connector shown with shell correctly engaged and collar forward in lock
position. Oil flow commences. Do not slide crosspiece forward.
White Insert Bag Nozzle with Gray Connector
1. Grasp the bag nozzle and slide the gray hose connector
on from the side.
2. With the hose connector in place, place fingers behind
flange on connector and press plunger forward to lock.
3. Connector shown with shell correctly engaged and plunger
forward in lock position. Since the White Insert Bag Nozzle is not
designed to work with the insert pressed forward, this configuration
may or may not work. If it does not, remove the gray hose connector
and order the blue hose connector from Gold Medal®.

Bag and Hose Connector Issues (Continued)
Lack of Oil Flow
If the oil does not flow after engaging plunger on gray hose connector, or if the crosspiece is inadvertently
pushed forward when using the blue hose connector with the white insert nozzle, the nozzle center slider
insert will be left pushed back into the bag, as shown above left.
To correct this, place fingers behind nozzle as shown above right. You will feel the center slider
protruding slightly into the bag. Holding the nozzle body from the front, press the slider from the back
side of the nozzle until it snaps outward into its correct position. The nozzle is now ready to be used with
a blue hose connector.
