"CG" SERIES VENTILATOR PRINCIPLE OF OPERATION
WASH CYCLE
The wash cycle is activated each time the exhaust fan is shut
off by pushing the “Start Wash” button on the Command
Center or, if equipped with optional time clock (“TC” Series), as
programmed on the clock. The “Wash On” light is illuminated
each time the wash cycle comes on, and hot, detergent
injected water is released into the interior of the ventilator for
the time set on the wash timer.
This hot detergent water washes the day’s grease, dust and
lint accumulation from the interior of the ventilator flushing it
down to the main gutter which slopes to a pre-flushed drain
which leads to the building drain system. Spray nozzles are
located on 8" to 10" centers on the two wash pipes (BAFFLES)
mounted on the interior back wall of the ventilator. (Refer to
Figure 3) At the end of the wash cycle, the water is
automatically shut off, and the interior of the ventilator is clean
- ready for the next day’s operations.
There are three standard wash cycle times that are set
depending upon the type of cooking equipment being used.
The settings are 3 minutes for light-duty equipment, 5 minutes
for medium-duty equipment, and 9 minutes for heavy-duty
equipment. However, adequate cleaning is dependent upon
water pressure, water temperature, daily grease accumula-
tion, the length of the wash cycle, frequency of wash cycle and
the type of detergent being used. It may be necessary to
increase the wash time to the next higher setting to achieve
proper cleaning.
