4.— Cut the Ceiling Tile
a. Mark the location of the PCM 340 on the |
location when the tile is replaced. |
TIP: Mark the screen direction on back |
of the tile (for example with an arrow or |
“to front”) to help orientation of tile when |
replacing it after cutting |
b. Measure the distances X and Y (see the figure |
at right) from the inner vertical section of the |
front and left |
the Pipe Adapter Plate. |
Using the X and Y dimensions, mark and cut a |
hole for the slotted pipe in the ceiling tile. |
TIP: Place the tile on a box and mark the |
center of the hole on the underside of the |
tile. Use a hole saw bit to start to cut the |
hole by hand (turning bit counter clock- |
wise) to avoid damaging the tile. When the |
drill bit is through the tile, turn the tile over |
and finish cutting from the top side |
