HOW COMPOSTING WORKS

Composting is the natural process of decomposition that can be helped along by
providing the ideal conditions to help your composting toilet work at peak performance.
The ideal conditions for decomposition to occur depend on several factors: oxygen,
temperature, moisture content, and the carbon/nitrogen ratio.

Oxygen

Oxygen is very important in composting. Your compost should be aerated in order to
encourage aerobic bacteria growth. Aerobic bacteria are bacteria that grow and live 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 should be
turned three times per week (6 complete turns of the drum).

Temperature

Temperature is another important consideration when composting. Optimal composting
temperatures range between 70-100 ° F (21-38 ° C). Decomposition will slow
significantly or stop completely if the compost becomes too cold (below 55 ° F or 13 °
C). If you are in an area that experiences temperatures below 55 °F (13 ° C) additional
heat is required if the composting toilet will be used continually or frequently. If used
for intermittent cottage application (3 - 4 weekends throughout the cold season) no
additional heat is required. The unit will function as a holding tank until the temperature
warms up.

Moisture

Moisture is necessary to achieve good compost. Your compost should always be
damp, like your garden after you have watered it. This moisture allows the bacteria to
travel 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 will
slow or cease. When adding water to the compost, you are aiming for damp compost,
not saturated. Too much liquid in the compost limits the amount of oxygen that aerobic
bacteria require to survive. If normal urination is not enough to maintain the correct
moisture level in the compost, we encourage you to add additional water to the drum.

Carbon/Nitrogen Ratio

Almost all organic material will compost. The proper bulking material and human waste
should be added to the composting toilet. In order to maintain a good balance between
carbon-rich materials, SUN-MAR Compost Sure Green and nitrogen-rich human waste
should only be added to the toilet.

THE SUN-MAR MOBILE/SPACESAVER TOILET

The key to the success of the MOBILE / SPACESAVER lies 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 thermostatically controlled
heater and fan assembly to help evaporate liquid and should be used where there is a
constant electrical supply.

The Patented Bio-Drum

Unique to Sun-Mar, the patented bio-drum provides the necessary mass to maintain
good compost and allows easy aeration of the compost by simply turning the drum.
Excess liquid will exit through a screen in the bottom of the drum into the evaporation
chamber. Mixing the Bio-drum is accomplished by rotating the handle in a clock-wise
direction. Compost is removed from the drum by pulling out the white drum lock button
(under the footrest) and rotating the handle in a counter clock-wise direction.

The Compost Finishing Drawer

The compost finishing drawer sits in an opening under the footrest. Compost in the
drawer is isolated from mixing with new waste while resting for 4 weeks so that it can
finish composting.

The Evaporation Chamber

The evaporation chamber is the floor
of the unit under the compost finishing
drawer. This is the area where any
excess liquid will gather for
evaporation. A safety drain exits from
the back of the composting toilet
which will drain over-flow liquid that is
not evaporated to an approved facility.

Inspection

We recommend an inspection of the MOBILE/SPACESAVER toilet prior to installation and to make sure you have
received all of the parts required as listed below.

Attaching
and
Detaching
the
footrest

1. If there is any visible damage to the carton­ The contents of the carton should be inspected before signing the bill of
lading. Damaged units should be refused. Call Sun-Mar immediately.

2. If the shipper has left­ Report the damage immediately to the transport company and call Sun-Mar.

3. Soon after delivery, remove the MOBILE/SPACESAVER Toilet carefully
from the carton- If there is hidden damage, or for any service questions,
contact Sun-Mar to determine the best course of action.

1- 1” x 8’4” Drain Hose 1- 4” Diffusor (SPACESAVER)
1- Compost Sure Green 4- 2”x31” Vent pipe (SPACESAVER)

1. Turn the drum handle clockwise to rotate the patented Bio-Drum for mixing
and aeration. (The drum rotates counter-clockwise and the drum door
closes). This is how you will rotate the drum during regular operation.

2. Pull the drum locker button, (located under the footrest) and turn the handle
counter-clockwise to simulate removal of compost. This is how you will
remove compost during regular operation.

3. (110 volt AC units) Plug the unit’s electrical cord into a standard three-prong
electrical outlet, and feel the air movement from the vent outlet at the top of
the unit to ensure the vent system is working properly.

4. Pull out the compost finishing drawer at the bottom front of the unit. 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.

MOBILE: The fold up footrest attaches to the unit with hinges. To attach
the footrest, align the pin on the footrest hinge with the bracket above
the finishing drawer opening. Slide the pin into the bracket. Once the
footrest is attached it is easily folded against the unit and clipped into
place.

SPACESAVER: The footrest attaches to the unit
with the metal track above the finishing drawer
opening. To attach the footrest, incline the footrest at
a 45 degree angle to the floor as shown. Insert the
round top edge of the track on the footrest into the
round top edge of the metal track on the unit and
then lower the footrest to the floor. Note: Footrest

must be correctly attached before stepping on it.

MOBILE Toilet Installation

Anchoring the
Mobile
“S” Shaped
Bracket

‘L’ Shaped
Brackets

The mobile should be anchored if the unit will be installed in a vehicle that will move. There
are three anchoring brackets supplied with the unit which should be used to securely
anchor the toilet.
The ‘S’ shaped mounting bracket ­The ‘S’ shaped mounting bracket, (pictured below) is for attaching the top of the toilet to
the wall. (see diagram below)

1. Locate the ‘S’ Bracket (shown above), 2 nuts, 2 washers and
2 bolts.

2. Locate the two dimples (guides where to drill holes) that are just
left of centre, near the top of the unit.

3. Place the ‘S’ Bracket over the dimples to make sure the holes line
up. Using an electric drill with the drill bit(provided), drill a hole
through each of the 2 dimples on the top of the unit.

4. Place the ‘S’ bracket over the holes so that the top end of the
bracket is above the top of the unit (as shown in diagram left).
Once the bracket is in place, insert a bolt through each hole so that it is visible through the
vent hole in the top of the unit (see diagram below). Run a thin bead of silicone around the
stainless steel washer (provided) and place over the protruding bolt, on the inside of the
unit. Place a stainless steel nut over each protruding bolt and tighten.

Fastening the bracket to the wall:

1. Place the MOBILE against the wall where it will be mounted.

2. With a pencil, mark the location of the holes in the mounting
bracket.

3. Drill a small hole in each of the pencil markings to accept
anchoring screws. Use a #8 x 1” screw to anchor the
unit to the wall. Once installed, the vent pipe will hide the
bracket.

The ‘L’ bracket, (pictured left) is for attaching the toilet to the floor. (see diagram below)

1. Locate the ‘L’ Bracket in the desired location.

2. Remove the finishing drawer. Using the holes in the ‘L’ bracket as a guide, mark the
location of the two holes with a pencil. Use a drill with the drill bit (provided) to create
small holes in the side of the MOBILE tank being careful not to drill downward toward
the heating element.

3. Make sure the drilled holes line up with the holes in the
‘L’ bracket..

4. Place a small bead of silicone over the hole between
the ‘L’ bracket and the Mobile tank. Dip the bolt into
silicone and insert the bolt into the hole in the bracket
and through the corresponding hole in the Mobile tank.

5. Place a small amount of silicone into the centre of the
nut and fasten over the bolt to fasten the bracket.

Important: Ensure all bolts used for brackets are
sealed with silicone to prevent leakage.
