Electrical Requirements
The following power supply must be provided for your machine:
2556EX, 2557EX, 2563EX: 230V, 5760W, 50Hz
DANGER
Machine must be properly grounded to prevent electrical
shock to personnel. Failure to do so could result in serious
injury, or death.
Do NOT immerse any part of this equipment in water.
Do NOT use excessive water when cleaning.
Keep cord and plug off the ground and away from
moisture.
Always unplug the equipment before cleaning or servicing.
A 30 amp – 4 wire wall receptacle is shipped with each machine. This receptacle will accept the
attachment plug on the popper and must be used.
Your electrician must furnish sufficient power for proper machine operation. We recommend
this popper 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 Company’s
recommendation that this machine 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.
Note: The Discovery “uses” both “hot to neutral” legs, 120v. The machine does not
“use” the 208v or 240v, “hot to hot” connection.
Before You Plug In Machine
1. Make sure all machine switches are in the OFF position before plugging the equipment
into the receptacle.
2. Make sure the wall outlet can accept the grounded plugs (where applicable) on the
power supply cord.
3. The wall outlet 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.
5. Install the unit in a level position.

Final Preparations
WARNING
To Avoid serious burns, do NOT touch the kettle while

lead-in cord. Tighten the ring on the kettle lead-in plug.
If supplied with automatic oil delivery system:
Connect the clear oil line from the pump to the aluminum line from the popper with the supplied

receptacle.
Follow the instructions provided in the oil pump manual to set the oil delivery amount. The
proper amount of oil for the 32oz. Discovery is between 8oz. to 9.6oz.
To check for proper amount of oil, and assure oil is liquid; dispense a “shot” into a measuring

POPPING CORN
Standard Popping Instructions
1. Turn on all Switches.
2. When popping with coconut oil, be sure the oil is liquid. Dispense oil into a measuring
cup first then use that oil for the first popping cycle. The proper amount of oil for the
32oz. Discovery is between 8oz. to 9.6oz.
3. Note: If the machine is supplied with an automatic oil delivery system, follow the
instructions provided in the oil pump manual to set the oil delivery amount.
4. When the kettle is ready (about 5-8 minutes), the Light and Audible Signal turn on. Lift
the kettle lid and pour in 32 oz. of corn (use the supplied corn cup) and 8 teaspoons
(21 cc) of Flavacol. Close lid.
5. Press the RED oil pump button (if supplied). The proper amount of oil is pumped into
the kettle. The Light and Signal will turn off.
6. When the popcorn has completed popping, the Light and Signal will turn on. Dump the
Popcorn.
7. On the final kettle of corn, turn the “KETTLE HEAT” switch off, just as the lids are
forced open by the popping corn. This saves electricity, and helps eliminate smoke and
odor after you have stopped popping.
Remember:
If the kettle heat switch is turned on and the Signal is sounding one of the following
actions should be taken:
1. Load the corn and oil or
2. Dump the popped corn from the kettle or
