WHEN TO CHANGE THE KES FILTERS  

 

The Prefilter, Bag filter and Box filter must be changed on a regular basis to maintain the 
high  grease  extraction  efficiency  required  by  the  UL/ULC  listing.    Once  a  filter  clogged 
light comes on the filter has reached its grease holding capacity.  Further use will restrict 
exhaust air flow causing hood smoke capture problems and/or cause the clogged filter to 
blow out into the next filter or the exhaust fan.  Therefore the three particulate filters must 
be changed before the Filter Clogged lights activate and shut the unit down under normal 
kitchen operation.  This will provide simple uninterrupted operation for  your commercial 
kitchen operation.   

 

Determine the Filter Change Schedule  

 

When  the  STADIUM  unit  is  turned  over  to  you  by  the  installing  contractor  immediately 
change the Prefilters.  The Prefilters will probably be full of construction debris and this 
debris will effect the initial operation of the unit.    

 

PREFILTERS  

1. Enter the startup date on the attached FILTER FREQUENCY CHART.  This is the date 
the Prefilters were changed as well.  

2. Run the unit until the Prefilter Clogged lights turns on.  When the light comes on the unit 
will  shut  down.    Immediately  turn  the  Override  switch  clockwise  and  put  the  unit  into 
override.  The unit will come back on.  Change the prefilters at the end of the shift or the 
next day before cooking.  Write the date that the Prefilters were changed on the FILTER 
REQUENCY CHART under Filter Change No. 1/Actual.  

3. Determine the number of days between the Startup date and the Prefilter Change No. 
Actual date.  Subtract two days from this number.  Add the this number of days to the last 
actual prefilter change and enter this new prefilter schedule date in the sche dule under 
Filter  Change No. 2/Schedule.  Change the Prefilters on this new date. If the Filter light 
activates before this new date reduce the number of days to the next scheduled change 
by one day.  

 

BAG FILTERS  

1. Run the unit until the Bag Filter Clogged lights turns on.  When the light comes on the 
unit will shut down.  Immediately turn the Override switch clockwise and put the unit into 
override.  The unit will come back on.  Change the Bag filters at the end of the shift or the 
next day before cooking.  Write the date that the Bag filters were changed on the FILTER 
REQUENCY CHART under Filter Change No. 1/Actual.
