1.3 Installation Overview
•
Each APM2 consists of a room pressure pick-up, a reference space pressure pickup and a room pressure
monitor panel, which houses a differential pressure sensor.
•
The two pressure pickup ports are installed in single gang electrical boxes, which are placed in the room
walls.
•
Standard 0.25" (6 mm) O.D. flame retardent polyethelyne control tubing (such as CPChem UL 1820),
maximum 250 feet (76.2 meters) length, is run within the wall from the sensors to the monitor panel. In
some code jurisdictions, the tubing must be in EMT conduit. Tubing and conduit is provided by others.
NOTE:
Less that 10% or 10 feet (1.6 meters) of total control tubing can be used in a vertical rise. Maintain
tubing run on the same floor as the APM2.
•
Install in a triple gang-double deep electrical box (RACO 697, Appleton M3-350 or equivalent).
•
Secure the triple gang-double deep electrical box to the stud(s) by using the mounting hole in the side of
the electrical box (see figure below for mounting hole location). Drive the mounting screws from the inside
of the electrical box into the wall studs to prevent sharp objects from protruding into the electrical box.
•
Ensure the mounting is level and flush to the wallboard surface.
