Mounting
Observe these guidelines when mounting an FX-PCV:
Important:
When the air supply to the VAV box is below 10°C (50°F), make sure that any
condensation on the VAV box, particularly on the damper shaft, does not enter the FX-
PCV electronics. Mount the FX-PCV vertically above the damper shaft to allow any shaft
condensation to fall away from the FX-PCV. Additional measures may be required in some
installations.
• Ensure the mounting surface can support the FX-PCV and any user-supplied enclosure.
• Mount the FX-PCV on a hard, even surface whenever possible.
• Use shims or washers to mount the FX-PCV securely and evenly on the mounting surface.
• Mount the FX-PCV in an area free of corrosive vapors that matches the ambient conditions
specified in the
section.
