Mechanical Installation
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.
