Checking And Replacing The Air Filters - ABB ACS800 Hardware Manual

Checking and Replacing the Air Filters

Check the inlet air filters at a minimal interval of every 3 months and replace as need
depending on accumulated dust and the environment. Inlet filters should be changed
at a minimum ever year as part of standard preventative maintenance. The inlet
(door) filter may be accessed and replaced by the following procedure.
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
forward and slightly 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.
