c. Clear the housing of debris.
2. Reinstall the pump motor:
a. Make sure the "O" ring is prop-

Autofloat Switches

• The autofloat switches turn the bilge pumps On when water rises above a preset level.
• Test each autofloat switch often.
Autofloat switch testing:
1. Lift the float switch test button to
turn On the bilge pump.
• If the pump does not turn On, check
the fuse on the fuse block.
• If the fuse is good, but the switch
still does not work, it may mean the
switch is bad, or the battery is dead.
2. After testing, push the test button
all the way down to return the float
switch to auto mode.
When the test is completed on each float switch, you MUST push the test button ALL THE
WAY DOWN to reset auto mode!
