The pad filter support installation
1. Insert two straight tines behind the filter frame. (Frame shown depicts a cell opening in an existing spray booth exhaust bank). The straight tines will run vertically, up and down but can be positioned horizontally.
You may insert either the top or bottom pair, it does not matter which end is inserted first.

2. Push the wire support grid into filter frame, sliding grid up or down so that the remaining two straight tines can also be positioned behind the filter frame.
3. Once all four straight tines are behind the frame, slide the support to center it within the frame. It is not necessary to position the support perfectly.

It is not necessary to perfectly center the wire support.

4. Secure Andreae Filter within frame: tuck first rear pleat of the filter between bent tines and filter frame.
The tines will puncture the polyester backing of the filter when installing the Andreae High Efficiency Filter, but this does not affect the filter’s performance.
