Operation

Pump may be run dry for short periods of time.
Pump may be run against a closed discharge.
WARNING: Motor may get hot after
prolonged use, do not touch. Burns
may occur.

Maintenance

Check all electrical connections periodically.
Check seal area for signs of leaking.

Wiring Instructions

Make all electrical connections in dry locations.
In humid/wet environments, connections must be sealed to
prevent corrosion.
Protect the circuit with a correctly fitted fuse or circuit
breaker in the red/orange positive (+ve) lead, as close as
possible to the power source.
Connect the black negative (-ve) lead to the negative
battery terminal.
Inadequate voltage at the pump (not more than 3% below
rated voltage) may result in blowing fuses, poor pump
performance, or failure for the pump to start. See table for
wire sizing.
