Introduction
HOW YOUR COMPOSTING TOILET WORKS
The key to the success of the “CENTREX 2000 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.
Composting is a natural recycling process where human
waste and toilet paper are broken down by microbes
into minerals and converted back to earth. 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 the composting drum. Additional organic
material is introduced by adding “Compost Sure Blue”
(or 100% non-antibacterial wood shavings). 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 earth-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 returns to the top
dead centre position ready to receive more waste, the
input doors remains open.
Compost is removed from the drum periodically, by
pulling the white drum locker button (on the handle side
of the composting unit)out, and turning the handle
counter-clockwise so that the drum rotates clockwise.
When this is done, the output door stays open, and
compost falls into the second chamber;-the compost
finishing drawer.
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 rear of the drum
directly onto an evaporating tray beneath the screen,
and from there, overflows into the evaporating chamber.
The evaporating 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 drawers 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 3-4
weeks until it is time to remove more compost from the
drum.
- 2 - - 27 -
Evaporating Chamber
The third chamber is the floor of the Sun-Mar “CENTREX
2000 Family” which forms the evaporation chamber
from where excess liquids may be evaporated. You will
always see liquid in this area, which is waiting to be
evaporated.
In electric and AC/DC units, air is pulled through intake
holes at the rear of the unit; 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.
On non-electric or AC/DC units, when AC power is
unavailable, natural draft caused by the chimney effect
of the 4”(100mm) vent and assisted by the 12 volt fan
draws air into the unit and up the 4”(100mm)vent
stack.
In the electric 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 mostly off when
the chamber is dry. The heating system maintains
warmth in the evaporating chamber, and the indirect
warmth assists the composting process, without the
compost drying out. A safety drain exits from the side
of the composter which drains off any excess liquid to a
cess pool, recycling bed, or other approved facility.
Winter Use
Because "Sun-Mar" units are made largely of fiberglass
and high grade stainless steel, freezing temperatures
will not damage the composting unit. Composting action
decreases as the temperature drops, so for continuous
use, the composting unit should be kept constantly at or
above 55-60 degrees F (13-15 C). All exposed vent
stack should be insulated (right up to 2" or 5cm below
the diffusor) to minimize the condensation in the pipe
and avoid ice blockages. Drain pipe should be insulated or, in extreme temperatures, heat tape used to prevent ice blockages.
In extreme temperatures, an additional source of heat
will also be required.
If the compost is frozen in the drum, the unit may be
used periodically as a "holding tank", until the compost
warms up and the microbes emerge from dormancy.
Space should be made in the drum prior to freezing to
accommodate winter use. The drum should NOT be
rotated when the compost is frozen.
Make sure that the composting unit is protected from
snow and ice accumulation to ensure that moisture
doesn't get into the heater base. It is a good idea to
put a tarp over the composting unit to protect it from
snow.

Inspection
This chapter describes how to inspect your new Centrex 2000 prior to installation for damage and make
sure you have received all of the parts.
Inspecting
the unit for
damage
i) If there is any visible damage to the carton
the contents of car ton MUST be inspected before signing bill of lading. Damaged units
should be refused. Call Sun-Mar immediately.
Before signing the shipping papers and dismissing the driver.
ii)
ensure that the carton contents have been inspected.
If the shipper has left-
iii)
Report the damage immediately to the transport company and call Sun-Mar.
Soon after delivery, remove the Centrex 2000 carefully
iv)
from the carton
-
If there is hidden damage, or for any service Questions, contact Sun-Mar to determine
the best course of action.

Yourself with
the
Centrex 2000
Placement of
Unit
Check that the carton contains the vent stack (pipe, fittings, roof flashing and diffusor);
“Compost Sure”, rake, drain hose and fittings, etc. Notify Sun-Mar if you are missing anything.
i) Turn the drum handle clockwise to rotate the Bio-Drum for mixing and aeration. (The drum
rotates counter-clockwise and the drum door closes).

ii) Lift and remove the access door and rotate the drum until the drum opening is visible
through the the access door opening for adding “Compost Sure Blue”.

iii) Plug the unit’s electrical cord (Electric and AC/DC units) into a standard three-prong elec-
trical outlet, and feel the air movement from the vent outlet at the front of the unit to
ensure the vent system is working properly.
v) Pull out the compost finishing drawers at the bottom right of the unit.
vi) After the unit has been plugged in for ten minutes, place a hand on the floor of the
evaporating chamber (the area under the finishing drawer) to check it is warm to the
touch, and that the heater is working properly.
vii) Affix the “WARNING/CLEANING” sticker to the underside of the toilet seat cover, and check
that another is on the access port of the composting unit.
The unit should be installed so that the base is protected from weather. The rubber “u” channel at the bottom of the unit is well-sealed with silicone, but if the unit is sitting in water, has
snow melting against it, or rain pouring on it, this may eventually wear through and short out
the heating element. Install your unit with a protective cover of some kind around this area,
and do not install the unit in a pit where water can accumulate around it.

Installing the
“1 Pint” Low
Flush Toilet
1. Make sure the center of the floor flange is at least 11 inches
(280mm) from the back wall.
2. When Installing a new floor flange, make certain that the toilet
mounting bolts align properly with Sealand Traveler toilet mounting pattern.
3. Secure flange to floor using flat head screws through countersunk holes in flange. Insert bolts into slotted holes in flange
(Fig. A)
4. If toilet is being installed in a shower stall, apply a 1/4”(6mm) thick
by 3/4”(19mm) wide bead of glazing compound around the
circumference of the floor flange (Fig B).
5. Position floor seal by pressing the floor bolts up through the
holes in the seal.
6. Set toilet in place with bolts protruding up through mounting holes
in base (Fig C).
7. Install washers and hex nuts provided with toilet. Tighten nuts
down equally with standard 7/17” (12mm) open end wrench.
Remove excess Glazing compound from around base.
8. Connect water supply line to water valve (1/2” or 13mm MPT) inlet
using appropriate fittings (Fig D)
9. Turn on water supply and flush toilet to test for leaks.
10. Attach pedestal and pedal covers to toilet base. See instructions
below.
