Other types of liquid level devices may also be
used. Consult the factory for the liquid level device
best suited for your application.
Liquid level devices must be positioned far
enough to allow 6 minutes between starts.
If the pump motor cycles more than 10
starts per hour, it will over‐heat, resulting in
damage to the motor windings or control
box components.
