Fryer Operation
GBF − 35 / GBF − 50 Fryers
4.01.2 Controller − General Overview
● POWER UP:
Place POWER switch in [ON] position. Controller will power up and sound an alarm. The message “POWER
FAILURE [PRESS START TO PREHEAT]” is shown on the upper display screen . This is normal , intended to prevent
the fryer from beginning to heat while unattended, such as after power interruptions. Pressing the [START] key
silences the alarm and places fryer into PREHEAT mode. If HEAT switch is in the [HEAT] position, and
temperature setpoint is higher than the current actual oil temperature, heating elements will turn ON and
cooking oil will begin to heat.
CAUTION! DO NOT place HEAT switch in [HEAT] position unless vat is filled to the FULL level with cooking
oil (or water).
● PREHEAT:
Oil is heating and real ­ time actual oil temperature will be displayed on the lower display screen . When oil
reaches the programmed setpoint, the alarm will sound and upper screen will display the message “ALARM ‐
STIR OIL” . At this time, press the [ALARM] key and vigorously stir cooking oil. Controller enters a 10 seconds
delay ... typically, the oil temperature will drop when stirred and if temp drops below setpoint during the delay
time,
PREHEAT continues until it returns to setpoint. This process helps to ensure more consistent temperature
throughout the total volume of oil, leading to better cooking performance. Upon returning to setpoint, alarm
sounds again and upper screen shows “ALARM ‐ SETPOINT REACHED” . Pressing the [ALARM] key, places fryer
into READY state.
●
READY STATE:
Fryer is ready for cooking. The lower screen changes to display the current controller temperature setpoint. The
last cook settings used will be shown on the upper display screen .
While fryer is in PREHEAT or READY state, you may change cook settings either by selecting a different menu
item preset , see Section 4.01.5.2, Selecting a Menu Preset • OR • manually inputting different settings (time
and/or temp), see Section 4.01.3, Setting the Cooking Temperature & Section 4.01.4, Manually Setting the
Cook Time .
NOTE: If PASSCODE ENABLE is set to ON, you cannot manually set a different cook time without entering the
proper password. This lockout feature provides a measure of control over cooking procedures.
● START:
The current cook time setting for each basket side is shown on the upper display . To start a cooking cycle press
the [START} key + select side: [4]=Left, [6]=Right, [5]=Both . When the selected timer starts, the cook cycle
countdown appears in the lower display .
