3. (a) Check the DC fuse by pulling it out of the
fuse holder. (b) If the wire within the fuse is
burned and broken, replace the fuse with a 25
amp DC safety fuse. If the fuse blows again,
unplug the computer control unit from the wall

Pump was activated
When water rises in the sump pit and lifts the
float switch, the pump will begin pumping, and
the “Pump was activated” light and alarm will
turn on. The pump warning stays on to alert you
to the fact that the standby system was used to
empty the water from the sump. Try to
determine what caused the system to activate.
• Check the main pump for failure. It may not
be working, the float switch may be stuck,
or it may be too small to handle the inflow
of water.
• Make sure the check valve is working and
installed correctly. It may need to be
replaced.
• Make sure the discharge pipe is not clogged
or frozen.
• If the power was out, the backup pump was
automatically activated. You need to push
the BLUE button on the front of the control
panel to silence the alarm.
REPLACING THE PUMP
Unplug the main AC pump when installing the
backup pump to avoid electric shock. Failure
to do so could cause serious injury or death.
Review the safety instructions on page 1.
