Maintenance – Media Panel Type
Generally the life of the Odor Control Media is the number
of days shown in Table T-5-2-1. However
every cooking condition varies and therefore it is important to establish
the frequency of inspection and
replacement of the media.
If the unit has Double or Triple Pass Odor Control the life expectancy between
the first, second and third pass will vary. To assist in determining if the media has expended an Odor
Control Media Monitoring Tube is provided (see Figure 5-2-1). This tube is mounted in the odor control
plenum of the ClearAir Unit so that it is exposed to the odor molecules in the exhaust air, the same as the
Media Modules. The tube is identified by the label shown in Figure 5-2-2. The label includes an area
where the date of the last inspection and Media Panel installation can be filled in with a grease pencil.
To inspect the Media Monitoring Tube, using an open end
wrench, turn the tube nut counter clockwise
and remove the Monitoring Tube assembly. The Media starts off a dark purple so if the media in the
Monitoring Tube is Dark Purple it is still good. If the Media is dark brown, break a granule open and if the
inside is light tan there is very little life left and the Media should be replaced. If the outside of the
granules are light tan the Media is completely expended and the Media must be replaced.
