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
20 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 using, 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. The level can be double-
checked by viewing the dark waste line through the side of the semi-transparent holding tank
from the starboard aft cockpit locker.
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.
11.3 COOKTOP (Optional)
The galley cooktop aboard your boat is powered by AC electricity. To use it, make sure the
cooktop breaker on the AC panel is ON and that a supply of AC power is present.
Do not leave the cooktop ON while unattended.
