sition if an external control switch is used. Required

Managing ON/OFF switching activity
Your submersible electric motor accumulates a
certain amount of heat each time it is switched on. It
must run for a period of time during which it has the
opportunity to dissipate the heat. If too many starting
cycles are called for your motor and/or pump may be
damaged. Observe the starting specifications of the
motor.
