Introduction
HOW YOUR COMPOSTING TOILET WORKS
Composting is a natural recycling process where human
waste and toilet paper are broken down by microbes
into minerals and converted back to ear th. Heat, oxygen, organic material and moisture are needed to transform this waste into good fertilizing soil, perfect for your
flower beds.
Oxygen is provided by the ventilation system, and by
tumbling of the composting drum. Additional organic
material is introduced by adding a compost bulking mixture. The waste entering the toilet is approximately
90% water content. Any excess liquid which is not
absorbed will collect on the floor of the unit (evaporation chamber) where it may be evaporated into water
vapor and carried back to the atmosphere through the
venting system. The remaining waste material is transformed into an inoffensive ear th-like substance.
The Composting Chamber
The composting chamber is in the form of a Bio-drum
which holds the natural compost heat, provides the necessary mass to maintain a good compost, and is rotated by turning the handle to achieve perfect mixing and
aeration.
During mixing, both the input door and the output doors
will remain closed. When the drum retur ns to the top
dead centre position ready to receive more waste, the
doors will remain open.
A drum stopper, on the right side of the unit (handle
side) automatically holds the Bio-drum in a top dead
center position so that it is always positioned to receive
new material.
To ensure that the compost remains moist, but does not
get too wet (between 40 and 60% moisture content is
ideal), any excess liquid which the compost cannot
absorb drains through a screen in the bottom of the
drum directly onto an evaporating tray beneath the
screen, and from there, overflows into the larger evaporating chamber. The eva porating tray can be removed
periodically to remove peat moss debris that has accumulated.
Compost Finishing Drawer
The compost finishing drawer is at the extreme right of
the unit below the composting drum, and just above the
evaporating chamber. Compost from the drum is isolated in the drawer where it is allowed to ‘finish’ composting. For seasonally used units, several drawer s of
finished compost are normally removed at the beginning of the season. Otherwise some composted material can be extracted into the drawer and left there for
2 months until it is time to remove more compost from
the drum.
Evaporating Chamber
The third chamber is the floor of the Sun-Mar “CENTREX 2000 AF” which forms the evapor ation chamber
from where excess liquids are evapor ated. You will frequently see liquid in this area.
- 3 - - 32 -
The key to the success of the “CENTREX 2000 AF Family” lies in it’s three chamber design. Each of the three chambers; composting, compost finishing, and evaporation have their own independent environments for optimum efficiency.
In Electric or AC/DC units, air is pulled through intake
holes at the rear of the unit and down the toilet; over
the evaporating chamber, and up the 2”(50mm) vent
stack which exits from the front of the composting unit
when AC power is being used.
When using the NE or AC/DC units and AC power is
unavailable, natural draught caused by the chimney
effect combined with a 12 volt fan draws air into the unit
and up the 100mm vent stack.
In Electric or AC/DC units using the AC mode, the evaporation process is further assisted by a thermostatically controlled heating element in a separate sealed compartment under the evaporating chamber. This heater
is on when there is liquid in the evaporating chamber,
and largely off when the chamber is dry. The heating
system maintains warmth in the evaporating chamber,
and the indirect warmth assists the composting
Winter Use
Because “Sun-Mar” units are made of fiberglass and
high grade stainless steel, freezing temperatures will
not damage the composting unit. Composting action
decreases as the temperature drops, so for extended
use, the toilet should be kept constantly at or above
55-60 F(13-15 C) degrees. All exposed 2“(50mm)
vent stack should be insulated to minimize the condensation in the pipe and avoid ice blockages.
In extreme temperatures, an additional source of heat
will also be required. It is also advisable for residential
applications in extreme climates to install an electric
plumbing tape inside the 2”(50mm) vent to prevent
icing.
If the compost is frozen in the dr um, the unit may be
used periodically as a “holding tank”, until the compost
warms up and the microbes emerge from dor mancy.
Space should be made in the drum to accommodate
winter use. The drum should NOT be rotated when the
compost is frozen.

Basic Maintenance Instructions
Sealand toilet and 'Centrex Family' Central Units
The toilet is porcelain and should be cleaned with hot water or bio-degradable products to avoid damage
to the compost. If required 'Compost Quick' or Baking Soda can be used diluted in hot water.
Three times a week weekly maintenance:
Turn drum to reveal waste inlet hole through access por t and add compost mix at the rate of 1 cup
(250ml) per person per day. (Scoop provided is 2 cups or 500ml)
Rotate handle clockwise to mix contents of Bio-drum and give 6 complete revolutions of the drum - (3640 rotations of the handle). Ensure that the drum door opening is in the vertical position at the end
after hearing the 'click' of the catch.
Check compost volume and condition in Bio-ddrum
and:
If the waste in the Bio-drum is too wet add wood shavings to improve aeration.
If composting is too slow add a compost accerant every second week, and ensure that the dr um is not
more than 1/2 full. If it is, follow the instructions for the emptying cycle.
Monthly maintenance and emptying cycle:
Rake out evaporation chamber with rake provided. For units with one, (Centrex 1000, 2000, & 3000
units) the black evaporating tray should be removed, solid matter tipped into the finishing tray and then
replaced beneath the drum screen.
Empty out the collection chamber ready to receive fresh material.
Attention: the composting unit must remai
n plugged in to an electrical outlet continuously to function
odourlessly. The AC/DC units should have both fans running while used in electric mode to prevent recirculation
between vent stacks. If you will be away from the residence where the composting unit is
installed for longer than three days, the power may be disconnected while the composting unit lays dormant.
Composting Drum: Waste and
bulking mixture collect for
decomposition
Finishing Drawer: Where
compost is put to ‘finish’
Evaporation Tray: Extends the
surface area of the evaporation chamber
Evaporation Chamber: This is
where you will frequently see liquid collecting.
