HOW COMPOSTING WORKS
Composting is the natu al p ocess of decomposition that can be helped along by
p oviding the ideal conditions to help you composting toilet wo k at peak pe fo mance.
The ideal conditions fo decomposition to occu depend on seve al facto s: oxygen,
tempe atu e, moistu e content, and the ca bon/nit ogen atio.
Oxygen
Oxygen is ve y impo tant in composting. You compost should be ae ated in o de to
encou age ae obic bacte ia g owth. Ae obic bacte ia a e bacte ia that g ow and live in
the p esence of oxygen and a e ve y efficient in b eaking down waste. To ae ate the
compost and encou age the g owth of these bacte ia, the compost d um should be
tu ned th ee times pe week (10 complete tu ns of the d um).
Tempe atu e
Tempe atu e is anothe impo tant conside ation when composting. Optimal composting
tempe atu es ange between 70-100 ° F (21-38 ° C). Decomposition will slow
significantly o stop completely if the compost becomes too cold (below 55 ° F o 13 °
C). If you a e in an a ea that expe iences tempe atu es below 55 °F (13 ° C) additional
heat is equi ed if the composting toilet will be used continually o f equently. If used
fo inte mittent cottage application (3 - 4 weekends th oughout the cold season) no
additional heat is equi ed. The unit will function as a holding tank until the tempe atu e
wa ms up.
Moistu e
Moistu e is necessa y to achieve good compost. You compost should always be
damp, like you ga den afte you have wate ed it. This moistu e allows the bacte ia to
t avel a ound in the compost so that they can speed decomposition by digesting the
waste. If the compost is too d y, the bacte ia cannot su vive and decomposition will
slow o cease. When adding wate to the compost, you a e aiming fo damp compost,
not satu ated. Too much liquid in the compost limits the amount of oxygen that ae obic
bacte ia equi e to su vive. If no mal u ination is not enough to maintain the co ect
moistu e level in the compost, we encou age you to add additional wate to the d um.
Ca bon/Nit ogen Ratio
Almost all o ganic mate ial will compost. The p ope bulking mate ial and human waste
should be added to the composting toilet. In o de to maintain a good balance between
ca bon- ich mate ials (SUN-MAR Compost Su e Blue) and nit ogen- ich human waste
only.

THE SUN-MAR CENTREX 3000 TOILET
The key to the success of the CENTREX 3000 lies in its th ee chambe design. Each of the
th ee chambe s; patented Bio-d um, compost finishing d awe , and evapo ation chambe ,
have thei own independent envi onments fo optimum efficiency. The CENTREX 3000
elect ic ve sion has a the mostatically cont olled heate and fan assembly to help evapo ate
liquid and should be used whe e the e is a constant elect ical supply. The CENTREX 3000
NE (non-elect ic) ve sion is fo use whe e the e is no continuous elect ic supply. The
CENTREX 3000 NE has no heate but does include a 12 volt fan. Odo less ope ation is
achieved by a 4” vent assisted by the fan which acts like a chimney c eating a pa tial vacuum
within the unit.
The Patented Bio-D um
Unique to Sun-Ma , the patented bio-d um p ovides the necessa y mass to maintain good
compost and allows easy ae ation of the compost by simply tu ning the d um. Excess liquid
will exit th ough a sc een in the bottom of the d um into the evapo ation chambe . Mixing the
Bio-d um is accomplished by otating the handle in a clock-wise di ection. Compost moves
automatically th ough the d um with SUN-MAR’s unique Autoflow ® techology.
The Compost Finishing D awe
The compost finishing d awe sits in the opening in the f ont ight of the unit. Since the
CENTREX 3000 automatically discha ges finished compost into the collection chambe at the
end of the unit, this d awe is used only if you need to emove all compost f om the d um.
Removal of the compost finishing d awe and access panel allows access to the evapo ation
chambe fo cleaning and maintenance pu poses.
The Evapo ation Chambe
The evapo ation chambe is the floo of the unit unde the compost finishing d awe . This is
the a ea whe e any excess liquid will gathe fo evapo ation. A safety d ain exits f om the left
side of the composting toilet which will d ain ove -flow liquid that is not evapo ated to an
app oved facility.
The Collection Chambe
CENTREX 3000 units inco po ate SUN-MAR’s
unique Autoflow ® technology. As the d um otates,
compost moves automatically th ough the d um and
into a sepa ate collection chambe located nea the
end of the unit.

The vent stack (shown in diag am) should end
app oximately 30” above the peak of the oof so that
it is less subject to downd aft. Whe e the pipe is
taken th ough the oof, a oof flashing may be
equi ed to seal the installation. If you a e in an a ea
whe e snow shea is a dange , you may wish to
install a heavie pipe a ound the vent pipe whe e it
exits f om the oof. If you do choose to do this,
ensu e that you seal the a ea between the pipes
with a wate p oof substance to p event leaks.
When it is necessa y to lead the vent th ough a wall,
connect one 45° elbow on the vent outlet on the unit.
Using a hole saw o othe app op iate tool, cut a
hole th ough the wall boa d behind the unit so that
the vent pipe can be inse ted into the 45° elbow. Cut
a simila hole on the othe side of the wall that is
slightly highe than the inne hole so that the vent
pipe will be angled upwa d at 45°. If installing
th ough an exte io wall, wate p oof sealant will be
equi ed a ound the vent pipe whe e it eme ges f om
the building.
The diffuso p ovided with the unit is a simple device
to be installed at the top of the vent stack with the
la ge pipe p ot uding above the smalle . To install,
simply glue the diffuso ve tically on the topmost
section of vent pipe. The diffuso design encou ages
upd aft, and discou ages wind and weathe f om
going down the vent stack. We do not ecommend
installing anything else on the top of the vent as it
could impede the venting. Unlike wind tu bines,
diffuso s a e less likely to f eeze in winte , and a e
mo e effective in calm weathe .
The safety d ain
MUST
be connected as it will be equi ed in all Cent ex 3000 NE
installations o Cent ex 3000 elect ic with ult a-low flush toilets.
- Remove the o ange cap f om one side of the ove flow d ain assembly.
- Place a 1” hose clamp ove the end of the d ain hose that will be connected to the
ove flow d ain assembly.
- Push the d ain hose ove the ibbed end of the ove -flow d ain and clamp with the 1”
SS hose clamp.
- Connect the 1” hose to an app oved d ainage facility.
- The safety d ain is g avity fed. The d ain hose must be below the level of the safety
d ain in o de to function.
The following a e possible options to take ca e of the liquid :
- Feed into a lined pit filled with g avel and sand. Such a
ecycling bed also ensu es a closed loop system.
- Feed into a small cesspit o “F ench d ain”.
- Plumb into an existing septic o holding tank line.
Installation should be in acco dance with applicable local
egulations.
