breakers. The motor will not restart until the
circuit breakers are reset.
NOTE

ately. Wait at least ten minutes before resetting the
control handle back to the ON position. If the over-
load unit continues to trip, operational problems ex-
ist. See TROUBLESHOOTING.
Always terminate incoming power to the control
box before investigating control box circuitry prob-
lems.
Always terminate power to the control
box before performing service func-
tions.
Power through the control box may be terminated
by moving the control handle to the OFF position,
thereby opening the circuit breakers. This stops
the pump, but does not terminate incoming power
through the field wiring connected to the control
box.
