C. Head Pump Out
When equipped with the head pump out option (stan-
dard feature on 280 Horizon & 285 Sundowner mod-
els), the waste can be removed from the tank at a pump-
ing station. A deck plate fitting labeled WASTE, is pro-
vided for this purpose. The holding tank capacities are
6 gallons/22.7 litres with the porta potti or 7 gallons/
26.5 litres with optional Vacu-Flush™ system. Most
marina fueling facilities provide service for waste pump
out.
To pump out the holding tank:
1. Connect the dockside pump out connection to the
WASTE plate located on the deck.
NOTICE
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
pumping equipment. The waste will be drawn from
the holding tank and into the pumping stations dis-
posal 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
water 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.

potti.
J - 5 GRAY WATER SYSTEM - OPTIONAL
The gray water system is optional on 280 Horizon and
285 Sundowner models. The water from the galley sink
and head sink drains into a 12 gallon (45 liters) holding
tank. The waste level indicator is located in the head
compartment. A pumpout fitting labeled WASTE but des-
ignated for gray water is provided on the port side of the
deck, at the stern of the boat, directly behind the FRESH
water fill fitting. The gray water fitting is directly in front
of the standard waste (black/gray water) fitting. The
gray water tank is located directly opposite the black/
gray water tank, under the aft cabin, on the port side.
NOTICE
Certain geographical areas have restrictions on
grey water being pumped or drained overboard.
Be sure to check all local, state and federal laws
in the boating area.

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.
