11.1 MARINE VACUFLUSH HEAD SYSTEM
Waste discharge regulations vary by location. Check with local authorities.
The waste system aboard your boat employs freshwater and a
vacuum generator. The freshwater pump breaker and Vacuflush
breaker must both be on (DC panel) for the system to work. Further
controls are located on a panel in the head (shown).
Refer to the manufacturer’s manual for more details.
When the foot-pedal of the toilet is depressed, waste is drawn
through the vacuum generator to the waste tank. Tank capacity is
10 gallons, which may seem small, but since each flush requires
about a cup full of fresh water compared to the several quarts of
sea-water using a conventional marine pump-head, the capacity is
more than adequate and there’s no odor. Waste can be discharged two ways:
(a) Via the shore-side pump-out fitting on deck labeled
WASTE using marina facilities. To effectively remove
all the waste from the holding tank, be sure to first turn
OFF the vacuum pump system and step on the head
flush pedal to remove all vacuum.
(b) Offshore beyond restricted waste disposal zones
by (1) OPENING the large waste thru-Hull discharge
valve, accessible to starboard and aft in the cockpit
lockers then (2) TURN & HOLD the switch in the Head
to the right to activate overboard pumping using the
macerator pump. The control panel lights indicate the
level of waste in the holding tank which is in the
compartment outboard of the engine. The level can
be double-checked by viewing the dark waste line
through the side of the semi-transparent holding tank.
WARNING Before activating this discharge, check to
insure compliance with local regulations.
11.2
DC REFRIGERATION (Optional)
The top-opening refrigeration unit utilizes a cold-plate
within the refrigerator enclosure which is chilled by a DC
powered unit mounted in the machinery space on the
port side. The refrigerator breaker on the DC panel must
be on for the unit to work. The thermostat for the system
is located in the icebox.
Once on, the unit will self-
regulate. For further information and troubleshooting
procedures, refer to the Seafrost operating manual.
The partitions in the refrigerator are designed to create
freezing temperatures next to the cold plate where the
ice-trays are located.
