(1) Responding to the Blue LED fi lter
prompt with “yes” starts a fi lter cycle
that lasts about as long as a cook cycle
(approx. 4 minutes). Communication
between the M3000 computer, the
manual interface (MIB board), and
the automatic intermittent fi ltration
(AIF board) handle the process.
(2) Actuators open and close the
drain valve and return valve, (3)
emptying and refi lling the frypot.
Auto Filtration (MIB and AIF)
The auto fi ltration system is controlled by the
M3000 computer, the AIF (Automatic Intermittent
Filtration) board and the MIB (Manual Interface
Board). The fi ltration is made hands-off by
actuators operating the drain and return valves.
The computer is programmable, and it allows fi lter
cycles to be launched after a set number of cook
cycles and a prescribed elapsed time.
The system can be set to lock out automatic
fi ltration during busy times, such as the lunch rush.
The fryer prompts for fi ltration by illuminating a
blue LED on the front and a text prompt on the
computer. The operator can say no; cooking can
continue.
Responding “yes” leads to communication between the MIB and the AIF boards. The MIB controls
and oversees the fi ltration; the AIF board operates the actuators, which open and close the valves.
The MIB is in the fryer cabinet. It is partially covered by a sheet metal cover and the LED display is
visible. Buttons behind the cover allow limited manual operation of the system and its valves. The
cover should be reinstalled after service.
The LED displays codes that can be used to diagnose failures (see chart on page 45).
An AIF board is mounted under each fry vat.
