Attach pressure tubing as follows:
1. Install the supplied silicone tube (with integrated spring) and attached barbed tube adaptor onto the end of
the 0.25 field tubing. Thread the tubes, with installed adaptor, through the conduit opening at the bottom
of the electrical box.
2. Next push the open end of the soft silicone tubing onto the APM2 pressure tube port labeled "HIGH".
3. For the most pressure stable operation, a Pressure Pickup Port installed in the reference pressure area is also
recommended. In this case, install the Pressure Pickup Port in a hallway or reference space.
4. Next push the open end of the soft silicone tubing onto the APM2 pressure tube port labeled "LOW".
