Note: Check to make sure the right oat switch is being used for the right application.
Normally Open - oat switches are open while hanging “down” and will close on a rising
liquid level. Typically used for “empty tank” applications.
Normally Closed - oat switches are closed while hanging “down” and will open on a
rising liquid level. Typically used for “lling tank” applications.
1. Determine desired cord tether length . See Figure 2.
2. Attach the Pipe Clamp at the desired location. See Figure 1. Adjust the tether length to achieve the desired
pumping range. Use Figure 2 as a guide and test system by lling tank and cycling the system to achieve actual
desired pumping range.
3. Tighten the clamp as tight as possible.
4. Electrical outlet must not be located in pump chamber. Electrical outlet voltage, piggyback plug voltage, and
pump voltage must match. Insert switch’s piggyback plug into outlet. Plug pump into piggyback plug and check
the system by allowing the system to cycle to insure proper operation.
Warning: Turn off all power when installing or adjusting unit.
Failure to turn off all power could result in serious injury or death!
Warning: End user to provide overcurrent protection rated at 240VAC
minimum, 15 Amps maximum.
Read instructions thoroughly. Check local codes and install to meet requirements.
