This machine is intended to be used with a Gold Medal popcorn popper with a proper power
cord to connect to the pump.
A certified electrician must furnish sufficient power for proper machine operation (reference unit
Data Plate for model specific Volts AC, Hertz, and Wattage requirements). We recommend the
popper powering this unit be on a dedicated and protected circuit. Failure to wire properly will
void the warranty and may result in damage to the machine. It is Gold Medal Products Co.’s
recommendation that the machine powering this pump be plugged directly into a wall outlet.
The use of extension cords is not recommended due to safety concerns and may cause sacrificed
and/or reduced performance. Make sure cord is located to prevent a trip hazard or unit upset.
Before You Plug In Machine
1. Make sure all machine switches on the popper are OFF before plugging the equipment
into the popper.
2. Make sure the popcorn machine can accept the grounded connection on the unit.
3. The wall outlet for the popcorn machine must have the proper polarity. If in doubt,
have a competent electrician inspect the outlet and correct if necessary.
4. DO NOT use a grounded to un-grounded receptacle adapter on the popper (where
applicable).
5. Install the unit in a level position.

Unit Installation
The unit needs to be placed in a cabinet enclosed on all sides in order for the heater to properly
maintain product temperature. Access will be required to the front of this area allowing
sufficient clearance to clean and maintain the pump and to add or remove boxes of oil.
Follow the instructions below to install the oil dispense unit:
1. Set B.I.B. unit near the open cabinet base, with the pump facing the operator.
2. Connect the pump’s discharge oil line (tube without the Universal Bag Connector) to
the metal oil line on the popper using the hose clamp provided.
3. Plug the power cord socket (from the popcorn machine) into the 6 prong plug located
on the side of the pump’s control box.
4. If equipped, connect the wire harness for the load cell sensor.
5. Insert oil dispense unit into the popper cabinet (position for use), then the unit is
ready to have oil installed, and set the Oil Level Indicator (Model 2257-00-003 only;
reference Oil Level Indicator section in the Instruction Manual for the popper).

Oil Installation - Attach Universal Bag Connector
This oil system is designed to be used with pre-melted oil. Gold Medal’s Backroom Warmer, Item
No. 2262, may be purchased for pre-heating the oil. If using coconut oil, Gold Medal’s Heated Line
Kit, Item No. 2457S (sold separately), is recommended to maintain the oil in the lines in a liquid
form.
IMPORTANT: DO NOT attempt to operate this system with a bag which has been
removed from the box. This unit is not intended for use with volatile food
products (i.e. real butter).
1. Load two boxes of pre-heated oil in unit. Use a maximum of (2) 35 pound boxes of oil.
Mount box so the bag nozzle is located towards the bottom of the box to permit a free
flow of oil from the bag.
2. Remove the cardboard cutout on the box to expose the bag nozzle, and then remove
the cap from the bag nozzle.
3. Attach the Universal Bag Connector from the oil dispense unit to the bag nozzle
(reference images below for Steps to Attach the Universal Bag Connector).
4. Once oil is connected, the unit is ready to be programmed for the oil dispense volume
delivered to the popper (reference Program the EZ Set Timer section).
Step 2: Grasp the Bag Nozzle
and slide the Bag Connector
on from the side.
Step 3: With the hose connector
in place, press plunger forward
to lock.
Step 4: Connector shown
with plunger fully forward
in lock position.

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.
