Operating the Oil Dispense Unit
Follow the steps below to turn on the oil dispense unit:
1. Turn Oil System Master Switch ON (switch located on Control Panel of the Popper).
This provides power to the oil dispense unit to activate the warmer/blower, and
heated line kit (if equipped). Keep cabinet doors closed for heater to maintain cabinet
temperature and keep oil at proper operating consistency.
2. To stop all oil heating, turn Oil System Master Switch OFF.
3. When the Oil Dispense Switch is activated, the oil light, on the popper control panel,
will light to indicate the oil pump is pumping.
Note for machines using coconut oil:
Coconut oil will congeal at temperatures below approximately 76°F (24°C). For
machines used daily, leave the Oil System Master Switch on at all times and keep
the cabinet doors closed to prevent the oil from becoming solid. If the machine has
not been used for several days, turn the Oil System Master Switch ON the night
before it is expected to be used.

Program the E-Z Set Timer
This section describes how to set the programmable timer; for B.I.B. Models manufactured prior
to 2003, see Setting Popping Oil Amount for 2257H (HD) section.
Follow the steps below to program the timer to dispense the oil amount needed to pop a batch of
popcorn. It is recommended to set the oil volume to approx. 30% of the raw popcorn charge used.
To program, use the Oil Dispense Switch and the Oil System Master Switch located on the control
panel of the popper.
Note: Take volume measurements from oil delivery tube located in popper above the
kettle. Allow kettle to cool completely prior to taking volume measurements.
Priming the Unit:
1. Turn Oil System Master Switch ON.
2. Hold a cup under the oil delivery tube in popper, PUSH and RELEASE the Oil Dispense
Switch to START dispensing oil.
3. As soon as oil flows steady, turn Oil System Master Switch OFF; unit is now primed.
Wait 30 seconds to allow oil to settle/drain before programming.
Programming the Unit:
4. Hold down Oil Dispense Switch and turn Oil System Master Switch ON, continue to hold
Oil Switch for 5 seconds until the indicator light (OIL Light or LOAD/DUMP Light) on
popper starts to blink ON-OFF, then release switch; unit now in program mode.
5. Hold a measuring cup under the oil delivery tube in popper; PUSH and RELEASE the
Oil Dispense Switch to START oil flow.
6. When correct amount of oil has been dispensed, PUSH and RELEASE Oil Dispense
Switch again to STOP oil flow. The Oil Switch may be pushed ON/OFF as many times as
needed to finalize (“top off”) the oil amount.
7. Turn Oil System Master Switch OFF, then back ON to SAVE the setting. Unit will now
dispense the “programmed” amount of oil when the Oil Dispense Switch is pushed. The
Oil Light on the popper will light continuously when oil pump is dispensing.
8. Wait 30 seconds to allow oil to settle/drain, then re-check the oil quantity.
Dual Timer Note:Units with two oil timer settings available must be set for Flexi-Pop®, if
available on the unit (Flexi-Pop option not available on Cornado units). Otherwise, the
two settings must be used for Salt/Sweet. Select one corn amount and program the first
timer; then select the other corn amount and program the second timer. (Pumps with
a single timer will only remember the last setting programmed.)
Manual Mode (Oil only dispenses when the Oil Dispense Switch is held IN):
OPTIONAL - Use to manually dispense oil, or for cleaning. Follow Step 4 then skip to Step 6.
To use a timer setting after using Manual Mode, the unit MUST be reprogrammed.

Setting Popping Oil Amount for 2257H (HD)
In March of 2003 we introduced the Bag-In-Box Oil System (Gold Medal Products Model No. 2257)
with an E-Z Set Timer Control. (See E-Z Set Timer Operation section on previous page).
For B.I.B. Pumps manufactured prior to 2003, the oil dispense time is adjusted by setting a timer
that controls how long the pump operates (Models 2257H single pump, 2257HD dual pumps).
Follow the steps below to adjust the oil amount for the 2257H and 2257HD.
Remove 2 Screws
B.I.B. Unit - Cover Plate
View inside the Cover Plate
Model 2257HD (has 2 Single Shot Timers)
Single Shot Timer Switches
Adjusting the Oil Dispense Amount
Step 1: Open the doors on the popper base cabinet
and locate the B.I.B. unit 2257H (2257HD).
R
emove the 2 screws that attach the cover plate
to
view the Single Shot Timer (2257HD has 2 timers).
Step 2:
Verify the current amount of oil charge.
Note:
Volume measurements should be taken
from the oil delivery tube located in the
popper above the kettle.
Hold a measuring cup under the oil delivery tube
on the popper, then push the Red Oil Dispense
Button o
n the Popper and measure the amount of
oil discharged.
Step 3:
The amount of oil dispensed is determined
by
how long the Single Shot Timer operates.
For each switch in the “ON” position, add the
numbers together for the total number of seconds
the pump wil
l operate.
Example:
The setting on the pump timer shown
below
has Switches 1, 2, 8 turned “ON”, and all
other switches are turned “OFF”
. Add 1+2+8 for a
total of 11 seconds.
General
Rule: 1 second equals about 1 ounce of
oil.
This is not exact, but a good general rule for
adding or subtracting to the current oil amount.
So, to dispense 13 ounces of oil, start by setting the
pump timer to 13 seconds. Turn switch 1, 4 and 8
“ON”, and all other switches “OFF” (1+4+8 = 13).
Step 4:
Repeat Step 2, record the amount, then
readjust as needed. (For Model 2257HD follow the
same procedure for the second Single Shot Timer.)
Switches 1, 2,
and 8 are “ON”
