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.
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.
