NOTE: 
Change the pre-filter as 
soon as the "REPLACE 
PRE-FILTER" indicator 
glows in order to extend the 
service life of the filter pack. 
NOTE: 
The charcoal portion of the 
filter pack is an aid in 
controlling cooking odors 
only. It will not completely 
eliminate such odors. 
1.  The GREASE BAFFLE separates grease particles and water vapor 
  from the air stream by the centrifugal force of the air moving through 
  its inter-leaved baffle plates. Ejecta is collected in the GREASE CUP 
  through drain holes in the baffle frame and cabinet. 
  The GREASE BAFFLE POSITION MONITOR plunger switch controls 
  electric power to the ventilator fan. 
2.  The PRE-FILTER is composed of a replaceable media filter and a 
  filter-retaining gage. The pre-filter captures the bulk of grease vapors. 
  Pre-filter position is monitored by a vacuum switch, which is in the 
  control circuit of the cooking appliance contactor. 
3.  The FILTER PACK is composed of a high-efficiency filter to capture 
  grease vapors down to a very small particle size; and, an activated 
  charcoal filter to help control cooking odors. 
  The FILTER PACK POSITION MONITOR plunger switch is in the 
  control circuit of the cooking appliance contactor.
