Installation
3.3.1
Place the enclosed template on the duct at the desired mounting spot. Mark the six (6) holes to be drilled.
3.3.2
Drill two (2) large and four (4) small holes in the duct you want to mount the unit on using the template
provided. The two large holes (1 ½”) are for the sampling and exhaust tubes. The four small holes (1/16”)
are starter holes for the sheet metal mounting screws. Ensure that the intake and exhaust tube holes are
large enough to allow all the setscrew adapters to fit.
3.3.3
Place each of the four (4) sheet metal mounting screws in one of the shouldered holes at the corners of the
enclosure base.
3.3.4
Place the enclosure onto the duct to test for proper hole alignment. Place the unit against the duct in its
intended position.
3.3.5
Fasten the enclosure to the duct by installing the four (4) sheet metal screws.
