Wash Cycle Example
Extractor Wash Cycle – The Extractor Wash Cycle only comes on while the exhaust fan is on, typically dur-
ing cooking (Refer to Figure 2-12-1). Using Table T-2-16-1 on page 2-16, if the cooking equipment under the
Ventilator is Heavy Duty then the Extractor Wash would come on every 4 hours of fan operation, stay on for
3 minutes and then shut off. Refer to page 2-15 for additional details on the wash cycles.
Plenum Wash Cycle - The Plenum Wash Cycle only comes on while the exhaust fan is off (Refer to Figure 2-12-

Plenum Wash would come on every 16 hours of exhaust fan operation, stay on for 3 minutes and then shut
off. Typically the Plenum Wash Cycle will begin, if the number of fan on hours has been satisfied, immedi-
ately after the exhaust fan has been shut off. Refer to page 2-15 for additional details on the Wash Cycles.
