HOW COMPOSTING WORKS
Composting is the natura process of decomposition that can be he ped a ong by
providing the idea conditions to he p your composting toi et work at peak performance.
The idea conditions for decomposition to occur depend on severa factors: oxygen,
temperature, moisture content, and the carbon/nitrogen ratio.
Oxygen
Oxygen is very important in composting. Your compost shou d be aerated in order to
encourage aerobic bacteria growth. Aerobic bacteria are bacteria that grow and ive in
the presence of oxygen and are very efficient in breaking down waste. To aerate the
compost and encourage the growth of these bacteria, the compost drum shou d be
turned three times per week (6 comp ete turns of the drum).
Tempe atu e
Temperature is another important consideration when composting. Optima composting
temperatures range between 70-100 ° F (21-38 ° C). Decomposition wi s ow
significant y or stop comp ete y if the compost becomes too co d (be ow 55 ° F or 13 °
C). If you are in an area that experiences temperatures be ow 55 °F (13 ° C) additiona
heat is required if the composting toi et wi be used continua y or frequent y. If used
for intermittent cottage app ication (3 - 4 weekends throughout the co d season) no
additiona heat is required. The unit wi function as a ho ding tank unti the temperature
warms up.
Moistu e
Moisture is necessary to achieve good compost. Your compost shou d a ways be
damp, ike your garden after you have watered it. This moisture a ows the bacteria to
trave around in the compost so that they can speed decomposition by digesting the
waste. If the compost is too dry, the bacteria cannot survive and decomposition wi
s ow or cease. When adding water to the compost, you are aiming for damp compost,
not saturated. Too much iquid in the compost imits the amount of oxygen that aerobic
bacteria require to survive. If norma urination is not enough to maintain the correct
moisture eve in the compost, we encourage you to add additiona water to the drum.
Ca bon/Nit ogen Ratio
A most a organic materia wi compost. The proper bu king materia and human waste
shou d be added to the composting toi et. In order to maintain a good ba ance between
carbon-rich materia s, SUN-MAR Compost Sure Green and nitrogen-rich human waste
shou d on y be added to the toi et.

THE SUN-MAR MOBILE/SPACESAVER TOILET
The key to the success of the MOBILE / SPACESAVER ies in its three chamber
design. Each of the three chambers; patented Bio-drum, compost finishing drawer, and
evaporation chamber, have their own independent environments for optimum
efficiency. The MOBILE / SPACESAVER features a thermostatica y contro ed
heater and fan assemb y to he p evaporate iquid and shou d be used where there is a
constant e ectrica supp y.
The Patented Bio-D um
Unique to Sun-Mar, the patented bio-drum provides the necessary mass to maintain
good compost and a ows easy aeration of the compost by simp y turning the drum.
Excess iquid wi exit through a screen in the bottom of the drum into the evaporation
chamber. Mixing the Bio-drum is accomp ished by rotating the hand e in a c ock-wise
direction. Compost is removed from the drum by pu ing out the white drum ock button
(under the footrest) and rotating the hand e in a counter c ock-wise direction.
The Compost Finishing D awe
The compost finishing drawer sits in an opening under the footrest. Compost in the
drawer is iso ated from mixing with new waste whi e resting for 4 weeks so that it can
finish composting.
The Evapo ation Chambe
The evaporation chamber is the f oor
of the unit under the compost finishing
drawer. This is the area where any
excess iquid wi gather for
evaporation. A safety drain exits from
the back of the composting toi et
which wi drain over-f ow iquid that is
not evaporated to an approved faci ity.

The vent stack (shown in diagram) shou d end
approximate y 30” above the peak of the roof so that
it is ess subject to downdraft. Where the pipe is
taken through the roof, a roof f ashing may be
required to sea the insta ation. If you are in an area
where snow shear is a danger, you may wish to
insta a heavier pipe around the vent pipe where it
exits from the roof. If you do choose to do this,
ensure that you sea the area between the pipes
with a waterproof substance to prevent eaks.
When it is necessary to ead the vent through a wa ,
connect one 45° e bow on the vent out et on the unit.
Using a 2” ho e saw or other appropriate too , cut a
ho e through the wa board behind the unit so that
the vent pipe can be inserted into the 45° e bow. Cut
a simi ar ho e on the other side of the wa that is
s ight y higher than the inner ho e so that the vent
pipe wi be ang ed upward at 45°. If insta ing
through an exterior wa , waterproof sea ant wi be
required around the vent pipe where it emerges from
the bui ding.
The diffusor provided with the unit is a simp e device
to be insta ed at the top of the vent stack with the
arger pipe protruding above the sma er. To insta ,
simp y g ue the diffusor vertica y on the topmost
section of vent pipe. The diffusor design encourages
updraft, and discourages wind and weather from
going down the vent stack. We do not recommend
insta ing anything e se on the top of the vent as it
cou d impede the venting. Un ike wind turbines,
diffusors are ess ike y to freeze in winter, and are
more effective in ca m weather.
The safety drain shou d be connected as it wi be required.
- Remove the orange cap from one side of the overf ow drain assemb y.
- P ace a 1” hose c amp over the end of the drain hose that wi be connected to
The overf ow drain assemb y. Push the drain hose over the ribbed end of the
over-f ow drain and c amp with the 1” SS hose c amp. Connect the 1” hose to an
approved drainage faci ity.
- Drain hose insta ation is required for a app ications.
The fo owing are possib e options to take care of the iquid :
- Feed into a ined pit fi ed with grave and sand. Such a
recyc ing bed a so ensures a c osed oop system.
- Feed into a sma cesspit or “French drain”.
- P umb into an existing septic or ho ding tank ine.
Insta ation shou d be in accordance with app icab e oca
regu ations.
The fan wi run continuous y 24 hours per day. A ground fau t interrupter (GFI) circuit is
recommended for any unit insta ed in an environment where it wi be exposed to
moisture. This may be insta ed direct y on the wa socket or at the circuit breaker. If
you are in an area where you experience power f uctuations, you may wish to insta a
surge protector.

Initial Sta t Up and Use
These steps are on y used when starting up your MOBILE/SPACESAVER toi et for the
first time or when you have emptied the drum and need to re-start the compost.
After insta ation is comp eted, do the fo owing:
Step 1 : Spray Compost Quick: Remove the finishing drawer
and spray the who e inner f oor of the unit under the
finishing drawer. Spray Compost Quick into the patented
bio-drum and the inside of the finishing drawer.
Step 2: Pour 1/3 bag of Compost Sure Green into a bucket and add 2 quarts of
warm water. Add 1/2 of the Microbe Mix packet to the bucket. A ow
the Compost Sure Green to absorb the water (about an hour).
Step 3: Scoop the Compost Sure Green mixture into the patented Bio-Drum
through the opening under the toi et seat on the MOBILE/SPACESAVER
toi et. Rotate the drum to mix. The opening in the drum must remain open
under the toi et seat. The MOBILE/SPACESAVER toi et is now ready for
use.
Step 4: For e ectric units on y. The fan wi run continuous y 24 hours per day.
120 Vo t Use: P ug it in to a three prong e ectrica out et.
When you first start up the MOBILE/SPACESAVER toi et, it wi take approximate y 6 weeks at optimum temperatures (70-
90 ° F) before you wi have sufficient quantities of microbes in the drum to actua y achieve good compost. During this
time, the contents of the patented Bio-Drum start out as Compost Sure Green and waste. Over the first 6 weeks, you wi
notice that the compost wi ho d moisture and wi become more uniform y dark in co or.
During the first 6 weeks, you may notice that some Compost Sure Green has fa en through the drum screen onto the
evaporation chamber to the eft of the finishing drawer. This shou d be raked out and removed with the rake too provided
with the unit.
NOTE: Regula toilet pape may be used. Toilet pape is a good sou ce of ca bon fo you compost so it may be
added to the Bio-D um™

Every second day before turning the hand e, spray 3-4 sprays of
Compost Quick on the surface of the compost. Compost Quick is an
enzyme that wi speed up the composting process.
Turn the hand e in a c ockwise direction to mix and aerate the
compost. When mixing, ensure that the drum rotates 6 comp ete
revo utions (36 turns of the hand e).
The ho e in the drum must be open under the toi et seat, ready to
receive waste.
Add one scoop of Microbe Mix to the patented bio-drum to ‘recharge’
the pi e. This wi he p to ensure your microbe co ony stays constant
and hea thy.
Rake the evaporation chamber: Remove the finishing drawer. Rake
any so id debris from the f oor of the unit under the drawer
(evaporation chamber), paying extra attention to the two back
corners of the unit as this is where debris may accumu ate. Remove
the so id debris.
C ean the drum screen. Spray the drum screen with Compost Quick
and et sit for 15 minutes (this wi he p to oosen the debris if the
screen is not too encrusted). Scrub the screen vigorous y with the
wire brush. If brushing the screen does not c ear it and iquid is sti
not draining through the screen, you may have to resort to having to
use a screwdriver or nai to puncture each ho e in the drum screen.
Remove compost from the drum. When the drum is ha f fu (even
with the midd e of the drum hub at the front of the drum) it is time to
remove compost. To remove compost from the drum:
See page 13 of your Owner’s Manua

Seasonal Use and Sp ingtime Sta t Up
Empty Compost f om Last Season
Before your first use of the unit, extract compost from the drum by re easing the drum ocker ( ocated
above the drawer opening), then rotate the hand e counter-c ockwise giving the drum one comp ete
revo ution on y. Compost from the drum wi drop into the finishing drawer. Empty the drawer and
repeat this procedure unti most of the compost is removed, eave 3-4” of compost. This wi be your
“starter base” for the coming season.
Rake
Remove the finishing drawer comp ete y and use the rake too to rake any oose materia from the
f oor of the unit. Pay carefu attention to the back two corners of the unit (near the safety drain), to
ensure that your drains do not get c ogged.
Add Wate & Mic obe Mix
Add some warm water to the remaining compost, enough to ensure that it is quite moist. A so, add
some Sun-Mar Microbe Mix (two of scoops) to give the compost pi e a “kick-start” and rotate the drum
severa times to mix. If your composting toi et is e ectric, p ug it in and use for another season.
Winte Use
No Winte Use
Just add water, ots of water. Soak the compost in the drum to prevent it from drying out before
Spring. Make sure to unp ug the unit if e ectric.
Occasional Winte Use
If the unit wi be used for 3-4 weekends throughout the winter season then it is considered occasiona
use. A of the same considerations shou d be taken with these units to winterize them. When the
temperature dips be ow 55 ° F (13 ° C), composting activity wi decrease dramatica y. These units do
not need to be kept warm and wi act on y as a ho ding tank during the winter months unti they warm
up enough in the spring to begin composting again. During the winter, the compost wi freeze into a
so id mass so the drum shou d not be turned as it may damage the composting toi et. With this in
mind, it is a good idea to remove enough compost before it gets too co d to make room in the drum
for winter use.
Heavy o Residential Winte Use
These units shou d be kept in a heated area and a winterization tips shou d be fo owed, inc uding
the fo owing:
1) Vent Pipe - a vent pipe shou d be insu ated if they are exposed to the outside or in an unheated
area. If you are in an area that experiences extreme winter conditions, we recommend that heat
tape shou d be app ied to the exposed vent pipe to prevent ice b ockages.
2) Safety Drain - a mode s; we recommend that the safety drain shou d be insta ed and insu ated
above the frost ine. There wi be ess evaporation in the winter so this wi he p with any excess
iquid. If possib e, heat tape can be app ied to the safety drain to prevent ice b ockage.
3) Keep it warm; If the composting toi et is used frequent y in the winter then the composting part of
the unit shou d be kept in a warm p ace. Be ow 55 ° F (13 ° C), composting actions s ows
dramatica y so if it is in a p ace that fa s be ow this temperature, a source of heat shou d be
provided for the unit so that it can keep up with constant use.
