3.0 Installation
The SRIM is available in two models suitable for wall (flush mount) and surface mounting (or
panel mounting). The front panel of the product and product rear housing are snapped together,
the two snaps are located on the left and right sides of the front panel. A 1.5mm 1/16 inch Allen
wrench or paper clip can be used to open the concealed snap fastening system.
The rear housing can be used to mount to a wall or into a 3 gang “off the shelf” electrical box.
Conduit (1/2”) or a PG9 cable connection are available for wiring to the terminals at the rear of
the unit. The rear housing acts much like a sub-base that does not have to be removed once
installed.
The front bezel contains the pressure sensor, PCBA and display. It is a complete module that
can be calibrated. The pressure and electrical connectors are disconnected simultaneously
when the front bezel is removed.
Before installing determine a good installation location. For Flush mount applications, the
corridor outside the isolation room is preferred. For Surface mount applications the unit may
be mounted on the duct work (avoid high vibration), a stable surface near the ductwork or
inside a panel.
