3.0 Installation overview

Each Setra Lite unit comes compete per order specifications to provide room differential
pressure sensing and an intuitive visual indicator of room pressurization status.

3.1 Prepare wall for mounting

1. Cut hole in wall for Setra Lite or install 1-gang electrical box
2. Install 1-gang electrical box for each Pressure Pickup Port (RPS), either horizontal ceiling
mounted or vertically mounted high on a wall surface
3. Ensure electrical boxes are level and flush to the finished wall surface
3.2 Install Pressure Pickup Port (RPS)
1. Install room-side Pressure Pickup Port, which transmits pressure to be measured by
Setra Lite.
Note: Reference-side pressure pickup is integrated into the main body of Setra Lite -
no additional Pressure Pickup Port is required for reference side.
2. Run tubing to Setra Lite electrical box, being careful not to crimp tubing in conduit or
within walls
3. Run all wiring to the Setra Lite electrical box.

3.3 Plumbing

Typically, a Pressure Pickup Port (RPS) is installed in the primary monitored room and Setra
Lite is installed in the reference area (typically a hallway). Installing a single gang electrical box
inside the room, typically high on the wall or flush-mounted to the ceiling is appropriate for the
Pressure Pickup Port. 1/8" ID soft platinum-cured silicon tubing is typically used to bring the
pressure signal from the Pressure Pickup Port to the pressure fitting on the back of Setra Lite.
Note: Caution should be taken to locate the Pressure Pickup Port and Setra Lite at least
six (6) feet from air turbulence that may originate from air supply diffusers, slot diffusers,
mobile equipment cooling fans, or other devices that may exhaust air in the direction
of the ports. Air velocity blowing directly on these ports can cause inaccurate pressure
measurement.
