Operation
Operate your bilge pump using the 2-position rocker
switch located on the helm station switch panel. The
AUTO switch position supplies constant power to the
water level sensor so water is pumped anytime it is
detected.
The rocker switch has a red LED indicator that will be
lighted anytime the bilge pump is running.
The MANUAL switch position supplies power directly
to the bilge pump. When the rocker switch is in the
MANUAL position, the bilge pump will run even if
there is no water in the bilge.
The rocker switch has a red LED indicator that will be
lighted anytime the bilge pump is running.
!
CAUTION
Keep the bilge pump switch in the AUTO
position anytime the bilge drain plug is in place,
whether the boat is in the water or on a trailer.
Keeping the switch in the AUTO position allows
the system to sense rainwater or melting snow
that might accumulate in the bilge.
!
CAUTION
The bilge pump will be damaged if it is run
continuously when no water is in the bilge.
!
CAUTION
Test your bilge pump and water level sensor
before each mission. Manually activate the
water level sensor when the rocker switch is in
the AUTO position and verify pump operation.
Clear away any sludge or debris that might
restrict the pump or water level sensor.
