Maintenance
Daily
If KFCC is configured with temperature interlock,
clean thermostat or sensor with cloth and degreaser .
Keep clean for best performance; can clean weekly
depending upon grease accumulation .
Weekly
Depending on grease production and grease filter type
in the hood, temperature thermostats or sensors can be
cleaned weekly .
Seasonal
If KFCC is configured with temperature interlock, may
have to change temperature settings if ambient kitchen
temperatures fluctuate between summer and winter
seasons .

Frequently Asked Questions
Regarding Temperature Interlock
What temperature is the thermostat/temperature
interlock set from the factory?
Thermostat style: 95ºF
Digital style: 90ºF set point + 10ºF hysteresis
How do I determine if the KFCC is configured
with thermostat style or digital style temperature
interlock?
Thermostat style interlock uses 5/8-inch diameter
sensor(s) mounted in either the hood capture area
or exhaust collar(s) . The KFCC will include a solid-
state relay with a 1-100 minute off-delay dial . Inspect
the sensor diameter or look inside the KFCC for this
solid-state relay .
Digital style interlock uses 1/4-inch diameter sensor(s)
mounted in either the hood capture area or exhaust
collar(s) . The KFCC will include a controller with
a digital read out, capable of displaying different
temperature values . Inspect the sensor diameter
or look inside the KFCC for this digital-displaying
controller .
Will the temperature interlock automatically start/
stop the fans?
When connected properly to the fan starters the
temperature interlock will automatically control
the fans without input from the user . However, the
intended use of the temperature interlock is as a
back-up to manual control .
With thermostat style interlock, what is the purpose
of the timer in the KFCC?
The timer is used to delay the shut down of the fans,
to prevent fan on/off cycling while the temperature
in the exhaust duct can reach steady state . Without
the delay, cycling could occur both on startup
or shutdown of cooking equipment . The delay is
typically set at 20 minutes .
How many individual breakers does the KFCC
require?
The number of individual breakers depends the
number of fans controlled and options included in
the KFCC . Each individual fan typically requires its
own breaker . The KFCC main power requires its own
breaker . Each light circuit is typically put on individual
breakers .
Can I still turn my fan on and off?
Yes, the temperature interlock is designed to operate
with a typical on/off switch . The fan may not turn off
immediately after turning the fan switch off, it will
sense when the cooking operations have cooled and
then turn off .
