Mounting
Observe these guidelines when mounting a 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 PCV
electronics. Mount the PCV vertically above the damper shaft to allow any shaft condensation
to fall away from the PCV. Additional measures may be required in some installations.
• Ensure the mounting surface can support the PCV and any user-supplied enclosure.
• Mount the PCV on a hard, even surface whenever possible.
• Use shims or washers to mount the PCV securely and evenly on the mounting surface.
• Mount the PCV in an area free of corrosive vapors that matches the ambient conditions specified
• Provide sufficient space around the PCV for cable and wire connections and adequate ventilation
through the controller (at least 50 mm [2 in.] on the top, bottom, sides, and front of the
controllers).
• Do not mount the PCV in areas where electromagnetic emissions from other devices or wiring
can interfere with controller communication.
• When using the PCV1617 or PCV1632 to replace an existing controller, plug the unused open hole
from the original controller mounting, if possible.
• Avoid mounting the PCV on surfaces with excessive vibration.
On panel or enclosure mount applications, observe these additional guidelines:
• Do not install the PCV in an airtight enclosure.
• Mount the PCV so that the enclosure walls do not obstruct cover removal or ventilation through
the controller.
• Mount the PCV so that the power transformer and other devices do not radiate excessive heat to
the controller.
