INSTALLATION
Unpack the switch carefully. Inspect all units for damage. Report any damage to carrier immediately. Check the
contents against the packing slip and purchase order.
Kenco’s Thermal Differential Flow / Level Switches are manufactured to the highest quality standards. These instruments
use electronic components that can be damaged by static electricity. Make sure that you are properly grounded before
starting installation. Insure that all electrical connections are properly made, and that there are no “floating” connections.
Mechanical Installation
The Series KTD Switches have a ¾” NPT (standard) process connection. When used as a level / interface switch, and
horizontally mounted, the sensor must be oriented so that the RTD’s are parallel with the liquid surface. When used as a
flow switch the sensor must be oriented so that the RTD’s are perpendicular with the flow direction.
Use a 1-1/8” open end wrench to tighten the sensor in the process connection. Use the hex flats on the sensor for
tightening. DO NOT use the instrument housing for tightening. Rotation of the instrument housing in respect to the
sensor can cause internal wiring damage, and will void the warranty.
