Fryer Operation
GBF-70 Fryer
The controller is equipped with a programmable FORCE FILTER feature, that can be set to force operators to
perform an oil filtration process after a set number of cooking cycles have been completed. The feature is
configured in User Settings, Section 4.01.10:
• FORCE FILTER
‐ [ON] or [OFF] ... Factory default = [ON].
[ON] = After completing a set number of cook cycles, as specified by FILTER COUNT, an alarm sounds and the
message “ALARM ‐ MUST FILTER OIL” appears on the Upper Display screen. Pressing the [ALARM] key
silences alarm and the controller enters FILTER MODE. The unit will be locked out
of further operation until
cooking oil is properly filtered.
[OFF] = After completing a set number of cook cycles, as specified by FILTER COUNT, an alarm sounds and
the message “ALARM ‐ FILTER OIL” appears on the Upper Display screen only as an alert. Pressing the
[ALARM] key silences alarm and returns fryer to READY status. You can continue to cooking operations,
however this alarm and alert message will continue appearing after every subsequent cook cycle until filtering
is performed.
• FILTER COUNT
‐ 1 to 20 ... Factory default = 4.
The number of cook cycles which may be performed before controller enters FILTER MODE. Controller counts
a cook cycle run as (1), regardless of whether one or both baskets are used.
• FORCE FILTER SNOOZE
‐ [ON] or [OFF] ... Factory default = [OFF].
Effective only when FORCE FILTER = [ON]
[ON] = Allows operator to cook one (1) additional load of product after FILTER COUNT is exceeded, before
unit enters FILTER MODE and is locked out of further operation.
[OFF] = Additional cook cycle not allowed.
Additionally, each Menu Item Preset has an available FISH FILTER setting ... when set to [ON] it overrides the global
FORCE FILTER setting and puts fryer into FILTER MODE after only (1) batch of that particular item is cooked. Setting
is typically used for seafood products to minimize possibility of flavor transfer. See Section 4.01.5.1 for more detail.
Never attempt to perform filter process when cooking oil is cold, as cold oil can possibly clog
and damage the filter system. Oil should be at a temperature of at least 200°F [93°C] before
attempting to filter.
To avoid possible burn injury, always wear thermal protection (gloves or mitts), while performing the filter
process. Fryer parts inside the cabinet become extremely HOT!
4.04 Filtering Used Cooking Oil Using On-Board System
This section explains use of the on‐board Oil Filtration System, for filtering and reconditioning of used cooking oil.
The process involves draining used oil into a Filter Pan which contains filter media. A filter aid/reconditioning
product is added, then the filter pump draws oil through the filter media, recirculates it back to the vat. The
process runs for several minutes to filter out debris and recondition oil by removing certain soluble impurities.
Performing the process as prescribed can effectively increase the useful oil life by as much as 50%.
As a typically practice, it is recommended that cooking oil be filtered, at least, after every eight (8) “basket loads”
of product have been cooked in the Fryer, e.g. both baskets dropped at the same time counted as (2) loads.
