Fire Mode
In the event of a fire, the hood exhaust fan(s) will turn
on at full power and the supply fan will turn off (default
setting controlled by others) regardless of current fan
operation. If the hood is in a wash cycle, the hood will
drain and the fans will turn on.
NOTE
The wash sequence of the hood is not designed for
fire suppression and will not engage in the event of
a fire.
Cleaning Cycle
Manual Engagement
The wash function is triggered by pressing the Clean
Hood button after the exhaust fans are shut down at
the end of each day’s cooking operations (pressing
the Fans On/Off button).
Hot water and detergent will fill the hood reservoir.
The soapy water will then be cycled through the hood
by the attached recirculation pump, cleaning both the
filter banks and the exhaust plenum area on a timed
cycle.
When the cleaning cycle is complete, the water
is purged from the reservoir by the pump and the
reservoir will again fill with clean hot water.
A rinse cycle will then run on a timed cycle and the
water will again be purged by the pump.
When the cycle is complete, the controller runs the
exhaust fans briefly to remove steam and excess
moisture from the exhaust system.
Automatic Engagement
The hood is equipped with an automatic timer. The
timer will automatically initiate the wash sequence
at the programmed time each day. All other washing
functionality will be the same as the manual
engagement sequencing.
