The standard Innova-Switch™has a .75 inch (19.05mm) MNPT mount designed for easy installation through a threaded port. Optional configurations include .5” (12.7mm) or 1.0” (25.4mm) MNPT and flange mounts. Conduit is recommended for all wiring to the switch.

*IMPORTANT*

WHEN INSTALLING YOUR SIERRA INSTRUMENTS 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.

*IMPORTANT*

THE SWITCH BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PROPERLY ORIENTED. 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. PROPER ORIENTATION IS MARKED ON THE SWITCH BODY FOR REFERENCE. SEE FIGURE 5.0 FOR DETAILS.
