Press the
ADD WATER
switch until desired water level is achieved. (It will
shut off automatically to avoid overflow.)
Press the
FLUSH
switch down for a moment, then release it. It activates a
macerator pump that siphons water and waste from the bowl, macerates,
and propels the effluent to a 20-gallon waste tank. The capacity is
generous since, unlike conventional marine heads that use several
quarts of seawater, each flush uses about a cup of fresh water.
Toilet can flush when the green “
OK TO FLUSH
” light is on. If the red “
DO
NOT FLUSH
” light is on, the system is either recharging the vacuum, or the
holding tank is full.
See the Sealand Vacuum toilet system Instruction manual for instructions
on safety, changing flush modes, service mode, cleaning, maintenance,
spare parts, clearing hoses during extended periods of non-use, clearing
blockage, locating leaks, winterizing and more.
The lights on the
DISCHARGE PUMP
control panel (see adjacent image)
indicate the level of waste in the holding tank. The level can be double-
checked by looking at the semi-transparent holding tank. Waste is
discharged in one of two ways:
1. Pumped out at an authorized pumping facility from the
WASTE
deck
fitting
.
To remove all the waste, turn off the vacuum pump system and
press the
SERVICE BUTTON
to remove the vacuum.
2. Discharged overboard with the
DISCHARGE PUMP
. Open the large
through-hull discharge waste valve, accessible under the cockpit
hatch, aft and starboard. Then insert the key in the
WASTE DISCHARGE
control panel (see sidebar). Turn and hold the switch clockwise to
activate overboard pumping using the macerator pump. Don’t leave
the key in the switch. Waste discharge regulations vary by location.
Ensure compliance with federal, state and local regulations
before discharging.
Normal household toilet tissues don’t dissolve or flow well in
low water consumption toilets. These tissues build up in a tank and
eventually the toilet system fails. Use rapidly dissolving single ply Scott
tissue
. To determine that a tissue will dissolve, immerse a square of tissue
in a jar of water and shake five times. It should disintegrate.

There are two 16,000 BTU heat pumps that heat or cool the interior and
pilothouse as separate zones. They use raw water (seawater) much like
the engines, for heat exchange. The heat exchangers extract heat from the
refrigerant for the cooling cycle, and by reversing the flow of refrigerant
they extract heat from seawater for heating. The heating cycle is effective if
the sea temperature is above 35 degrees.
