DRILLING INSTRUCTIONS

1. Locate the space between the two centermost* louver rows on the

cover (see Table1). As a check, this space is approximately equal in

distance from the two ends of the cover. The hole must be made

EXACTLY in the center of this SMALL SPACE between the two center-

most rows of louvers. Find this location using the template supplied or

from dimensions given on template and Figure 1.

2. USE OF HOLE TEMPLATE Center the template over the two

centermost rows of louvers on the side of the cover facing the room.

Slide two of the template legs into the uppermost louver openings as

shown in Figure 1. The other two template legs should be placed over

the two rows of louvers so that only the metal space between these

two rows is visible through the slot between the two legs of the template.

This is to assure that the template is squared off and so that the mark

made on the cover through the hole in the template (A) will be centered

between the two rows of louvers. Mark with pencil or scriber (Figure 2).

3. Drill or clean punch a

⁄32” diameter hole where marked. If drilling,

you will find it easier to drill a smaller hole on that mark. Then open

the hole to final

⁄32” diameter and deburr hole.
