INSTALLATION

Measurements between centerlines of panel cutouts are the minimum recommended.

Unpacking and Inspection
1.  Inspect shipping carton for obvious signs of mishandling.
2.  After removing the controller from the shipping carton, inspect it carefully for damage. Never attempt to install and use a damaged 

unit.

3.  Verify that the ordering code number indicated on the side of the controller matches what was ordered.
