The inlet air filter for the R7/R8 UL type 12
enclosure is located in the enclosure front

1. While holding the top of the filter frame, pull
up on the bottom of the frame. The filter
frame will slide up approximately 3/4 inch
and can then safely removed by tilting
away from the cabinet and lifting up.
2. Lay the filter frame on a flat work
surface. Remove the 3 retaining
brackets by squeezing the tabbed
corners in towards the middle of
each bracket until the bracket
clears the filter frame. Save these
brackets for replacement. Remove
and inspect the filter.
3. Install the replacement filter. Be
sure to tuck the filter into the grove
around the entire filter frame. This
is very important for proper
installation.
