The electrical connection must be carried out in
accordance with local regulations and follow the
National Electrical Code (USA) and the Canadian
Electrical Code. The pump must be grounded. The
operating voltage and frequency are marked on the
nameplate. Make sure that the motor is suitable for
the power supply on which it will be used.

To connect the pump for manual operation, insert the
pump plug into a wall socket. If a float switch is
included for automatic operation, it will be of the
"piggy-back" design. Insert the float-switch plug into
the wall socket, and insert the pump plug into the
back of the float-switch plug.
