instructions.
INSTALLATION
INSTALLATION INSTRUCTIONS
1. Carefully lift and place (2) 35 lb. boxes of liquefied oil onto the shelves of the oil system.
NOTE: Coconut oil must be pre-melted before proceeding. Use Gold Medals’ Backroom
Bag-In-Box Warmer Model #2262 (four shelf) or Model #2260 (two shelf).
2. Connect the discharge oil line to the metal line on your popper - using the provided hose clamp.
Note: If using Coconut Oil, Gold Medal recommends the use of the item #2457S – Heated Line Kit. Using
this kit will keep the oil in the lines liquefied.

Setting the Amount of Popping Oil with a Gold Medal BIB
System
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.
With the EZ-Set Timer System, it is not necessary to set a manual timer. To adjust the oil amount, follow these
instructions:
Holding down the RED Oil Dispense push button (on the popper) while turning on the Oil System Master
switch (on the popper), and continuing to hold the RED Oil Dispense button in for 5 seconds, puts the unit in
the program mode. The oil light (on the popper) will start to blink off and on indicating that the timer is in the
program mode.
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 push the oil Dispense switch
again 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.
You will need to perform this procedure with the oil lines full of oil. Otherwise, you are setting both the
amount of oil that goes in the kettle and the amount of oil required to fill the lines. Just fill the lines using the
process above, then reset the amount as described above.
NOTES:
Model 2257D is 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, 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.
The dead-leg connector
(With only one hose
connected to it) must be
installed on the to
p
box.
The Pass-thru connector
(With two hoses
connected to it) must be
installed on the bottom
box.

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 – 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 Bag dispensing Nozzle – White Insert
Blue Insert Bag Nozzle with
Blue/White Hose Connector

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 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.
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.
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. Oil flow
commences.
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.
NOTE: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 read
y
to be used with a blue hose connector.

CLEANING INSTRUCTIONS
SANITIZING INSTRUCTIONS
Your Bag-In-Box Oil system is all stainless steel construction. The exterior surfaces can be cleaned by
wiping oil spills with a dry towel, then wiping with another towel moistened with mild soap and warm water.
SANITIZING THE INTERNAL PARTS (tubing, pump, etc.)
1. Disengage the bag connector from the bag of oil and place in a pail of hot water and mild soap.
Approximately 1 gallon.
2. Push the dispense button to flush the system of oil. Make sure you have a container under the
discharge tube. Discard the oil.
3. Put the intake line in the hot water and pump it through the lines by holding the dispense button until the
pail is empty.
4. Fill the pail with a sanitizing solution. Gold Medal offers a product for this purpose, Chlor-Tech, part
number 1109. Put the bag connector in the pail of sanitizer. Pump it through the lines by holding the
dispense button until the pail is empty. It is not necessary to flush the sanitizer before the next step, but
you may flush with water if desired.
5. Before the next use, install the connector to a bag of oil and pump oil until oil is dispensed through the
discharge tube.
