Installation Instructions
Mounting
1. The TSB can be mounted in horizontal or vertical angles (do not
mount the switch facing down).
2. Install the TSB switch in the engine water jacket location
recommended by the engine manufacturer.
3. Install the appropriate adapter nut into the engine water jacket. Use
thread sealant such as Teflon
4. Insert the sensing bulb through the adapter nut. The sensing bulb
must be fully immersed in coolant/liquid flow so liquid flows
across the sensing bulb.
5. Tighten the 5/8-18 UNF-2A compression nut to complete a liquid
tight seal.
Wiring
CAUTION: DISCONNECT Electrical
Power before wiring.
1. See wiring schematic below.
Switch contacts are shown with no
temperature applied to the
TSB switch.
2. A spade (forked) terminal
is recommended for all TSB
switch connections.
3. Complete the wiring operation
making sure the voltage and current requirements are within the
TSB switch electrical rating.
Teflon is a trademark of Dupont.
