E. Pump Out Option
When equipped with the pump out option, the waste can
be removed from the tank at a pumping station. A deck
plate fitting labeled WASTE, is provided for this purpose.
The pump out option is available only on the 240 Hori-
zon, and Sundowner models. Most marina fueling facili-
ties provide service for waste pump out. See Figure G6.
To pump out the holding tank:
1. Connect the dockside pump out connection to the
WASTE plate located on the deck.
Usually the dockside pump out connection will screw
into the waste deck plate or has a rubber sleeve that
inserts into the plate and must be held in position
during the pump out operation.

2. Have the pumping station operator activate the pump-
ing equipment. The waste will be drawn from the
holding tank and into the pumping stations disposal
tank.
3. Remove the pump out connection from the deck
plate. Add 1 gallon of clean water to the holding tank
through the waste deck fitting using a dockside wa-
ter hose.
4. Repeat steps 1 & 2 above to pump out the water
used in step 3 to flush the holding tank.
5. Add waste holding tank treatment chemical available
from the dockside pumping station operator to the
head. Flush at least twice.

Be careful when handling and storing treatment
chemicals. Not only are they toxic, but they will
also stain and damage surrounding surface.
It will be necessary to remove the top holding tank of
the portable head to fill with water.
G - 5 SYSTEM MAINTENANCE
Be sure the batteries in the boat are properly charged.
Operating the pressure pump from a battery with a low
charge will result in pump cycling. This could lead to
premature pump failure.
The decomposition of waste produces a color-
less, odorless gas, methane, that is lighter than
air, combustible, and extremely lethal. Always
Waste Hose
provide sufficient ventilation when effecting re-
pairs to the waste system and allow no odor
from the waste system to go unresolved.
A. Clean Vents and Screens
Periodically remove the vent caps and check the water
tank vent(s). Clean the thru-hull vent fitting(s) of any
dirt, wax, plastic particles, etc. Always replace the caps

after cleaning.
Failure to keep the water tank vent fitting clean
will cause excessive pressure buildup within the
tank during filling. This can cause water tank
damage.
B. Winterizing the Water System
Winter lay-up service procedures should include a thor-
ough draining of the water system. Disconnect all ac-
cessible fittings. Blow out all lines. Be sure the water
tank, waste tank, pumps and lines are completely dry.
Freezing water can cause severe damage to all water
system components.
It may be necessary to disconnect the hose be-
low the faucet to remove excess water in the
lines to prevent freeze damage.
