Duct-type Installation
6. Install the box on the duct.
7. Connect the power and the outputs as shown in the ELECTRICAL
WIRING section.
8. Before mounting the cover of the sampling unit box, start the
ventilation feeding fan and check if there is any leakage. If
necessary, seal with air plugs.
9. The cover should be mounted using metallic screws (6-32
1/2”).
Note: To convert from CFM to velocity (ft./min.), divide the flow by the
area. Example: In a 2 ft. x 4 ft. duct, where the area is 8 sq. ft. and
the air velocity is 30,000 CFM : 30,000 CFM / 8 sq. ft. = 3,750 ft/
minute.
