less than half full. Symbol lighted yellow indicates
the tank is at least half full. Symbol lighted red
indicates the waste tank is full.
When the waste/holding tank is full, it must be
pumped out by an approved waste dumping sta-
tion. You should monitor the waste level carefully
and not allow the tank to become full. A lockout
system built into the toilet prevents it from ush-
ing when the holding tank is full. Never attempt
to ush the toilet or operate the sinks or shower
when the tank is full. An overlled waste tank will
force waste into the holding tank vent lter. This
will clog the lter, prevent the sinks from draining
and could cause damage to the holding tank. It
will also cause unpleasant odors or ood the head
compartment oor.
Notice:
The overboard macerator discharge pump
option for the waste holding tank is not avail-
able with the grey water system.

It is essential that the following items be done
periodically to maintain proper drainage of your
boat:
• Clean the cockpit drain rails with a hose to
remove debris that can block water drainage.
• Clean the hardtop leg drain holes. This is
especially important just before winter lay-
up.
• Clean the bilge pump strainers of debris and
check the bilge for foreign material that can
cause the pump or automatic switch to mal-
function.
• Frequently test the automatic bilge pump
switches for proper operation. This is accom-
plished by touching and holding the test but-
ton on the side of the pump until it activates
(about ve seconds). The pumps can also be
activated by ooding the bilge with a garden
hose until they activate.

• Flush all gravity drains with fresh water to keep
them clean and free owing.
• Clean and ush shboxes, coolers and storage
boxes with soap or a bilge cleaner and fresh
water after each use to keep them clean and
fresh.
• If your boat is equipped with the optional grey
water system, periodically clean and inspect
the drain sump system. Remove accumulated
debris and ush with fresh water. Frequently
test the automatic pump switch for proper
operation.
Note: All drains and pumps must be properly
winterized before winter lay-up.

NEVER USE HARSH CHEMICAL DRAIN CLEANERS IN
MARINE DRAIN SYSTEMS. PERMANENT DAMAGE TO THE
HOSES AND FITTINGS MAY RESULT.
