DRAWN BY: B. CREWS
Notes:
1.) The Sensor Should Be Mounted so
that the 6" Probe is in the Center of the
Return Air Duct. It Should be Mounted
Away from Fans, Elbows, Heating or
Cooling Coils or Other Equipment that
Could Affect the Measurement of
Relative Humidity. Also, the Sensor
Should be Mounted in an Area that
Receives Adequate Air Flow for Proper
Operation. The Sensor may be Mounted
Horizontally or Vertically to the Return Air
Duct. See the Sensor Mounting Diagram
Above.
2.) Unused Conduit Opening(s) Must Not
be Knocked Out to Prevent Dust or Insects
From Infiltrating the Sensor Electrical Box.
3.) The Sensor Probe Gasket Must Be
Installed Between the Back of the Sensor
Box and the Duct to Provide an Airtight
Seal.
