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.
4. Reinstall the 3 filter restraining
brackets. These will prevent the
filter from being pulled out of the
filter frame.
• Install the center bracket first.
• Install the 2nd bracket
overlapping the center bracket
by 1/2 to the left.
• Install the 3nd bracket
overlapping the center bracket by 1/2 to the right.
5. Install the filter frame back to the cabinet door. Carefully align the mounting hooks to
the slots in the cabinet door. The hooks should be pointing down. Press in at the
center of the filter frame with your knee and gently press down with your hands at
the top of the frame. The filter frame will slide down approximately
3/4 inch and should be sealed securely to the door around the entire filter frame.
