operation and maintenance manual in its entirety prior to unpacking and installing the unit.
The following precautions should be noted immediately:
•
WHEN INSTALLING YOUR INNOVA-SWITCH™ INTO A PIPE OR VESSEL USE A 1 1/8 INCH
(28.575mm) OPEN-END WRENCH TO TIGHTEN AT THE HEX FLATS OF THE MNPT OF A
STANDARD SWITCH. (IF YOU HAVE A NON-STANDARD SWITCH AN ALTERNATE SIZE
WRENCH MAY BE REQUIRED). DO NOT USE THE INSTRUMENT HEAD TO TIGHTEN THE
SWITCH TO THE MOUNTING PORT. ROTATION OF THE INSTRUMENT HEAD WITH
RESPECT TO THE SENSOR BODY CAN CAUSE INTERNAL WIRING DAMAGE (SEE
FIGURES 1).

THE SWITCH BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PARALLEL TO
THE LEVEL BEING DETECTED WHEN THE SENSOR IS INSTALLED HORIZONTALLY FOR
POINT LEVEL APPLICATIONS. LIKEWISE, FOR FLOW APPLICATIONS, THE SWITCH
BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PERPENDICULAR TO THE
FLOW BEING DETECTED. DUE TO THE PIPE THREAD MOUNTING, IT MAY BE
NECESSARY TO MAKE A TRIAL FIT, ADD OR REMOVE TEFLON TAPE OR OTHER PIPE
THREAD SEALANT, AND REINSTALL TO ACHIEVE A SATISFACTORY SEAL WITH THE
SENSORS PROPERLY ORIENTED. FOR VERTICAL INSTALLATION OF SENSORS FOR
POINT LEVEL DETECTION THE ORIENTATION MAKES NO DIFFERENCE. PROPER
ORIENTATION IS MARKED ON THE SWITCH BODY FOR REFERENCE (SEE FIGURE 5).
