Wiring the pump
1. Connect the brown wire from
the pump to the positive (+)
fused side of the battery.
2. Connect the black wire coming
off of the pump to the negative
(-) side of the battery.
3. Do not cut any wire insulation
more than 3" and keep all con-
nection above the water levels,
keep all connections high and
dry. A marine grade sealant/
liquid electrical tape is
recommended to seal loose
wire ends. A submerged splice
will render the warranty void.
4. Fuse all cartridge style pumps
at 5A.
5. Do not run pump dry for more
than 10 seconds.
6. If you are using a float switch
in conjunction with this pump,
be sure that the float switch is
higher than the impeller level
of the pump to assure proper
shutoff of the pump.
