Oil Installation –Oil Level Indicator
(BIB Units with a Load Cell)
A Bag-In-Box with an Oil Level Sensor is used with a Popper equipped with an Oil Level Indicator.
For poppers with a Membrane or Touch Screen control
panel, reference the Instruction Manual for the popper to set the oil level indicator.
The B.I.B. oil level sensor connects to the Oil Level Indicator on the control panel of the popper.
The illuminated, color coded indicator (from green to red) informs the operator when oil is
getting low. When indicator gets to yellow, oil level is reduced to less than 40%; oil should be
monitored more closely. When indicator gets to red, oil should be reloaded. Gold Medal
recommends resetting the oil level indicator each time oil is reloaded to ensure accurate oil level
indication (reference instructions below).
This oil system is designed to be used with pre-melted oil. Gold Medal’s Backroom Warmer, Item
No. 2262 (2262EX), 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).
Setting the Oil Level Indicator
The B.I.B. Unit holds a maximum of (2) 35 pound boxes of oil; one for use, and a second box, being
staged for use, when the first box is empty. Program the oil level indicator to show when the box
in use is getting low, thus informing operator to watch oil level/change connection to second box.
Program the Oil Level Indicator:
1. With Popper ON, turn Oil System Master Switch ON.
2. Load one full box of oil in the unit.
