7.3.2.7 Bilge Pump Switch

Half way down the right side of the panel, immediately
below the Panel Lights switch, is the momentary toggle
switch for the main bilge pump. This switch allows manu-
al control of the bilge pump and is energized regardless if

the momentary ON position and engages the bilge pump
while illuminating the LED on the toggle tip, indicating an
energized state. Releasing the toggle switch returns to
the OFF position and disengages the bilge pump.

The circuit breaker for the main bilge pump is located on
the Battery Switch Panel.

cooler level.

To turn your refrigerator off, turn the fridge’s internal
temperature control knob fully counterclockwise.

NOTE: If leaving the refrigerator on when away from the boat,
ensure the shore power cables are connected. (If equipped
with a battery charger, turn it on to prevent battery drain. If
equipped with an inverter, the batteries will automatically charge
if the AC panel is energized.)
