Every living organism consumes nutrients and create
waste. To transform waste back to nutrients and complete
this cycle, nature uses the processes of decomposition
and evaporation. As is often the case, nature seems
to be doing things in the best way possible.
That's why SUN-MAR toilets are designed to not only
harness these natural processes, but to optimize
and accelerate them.
Toilet waste is over 90% water content. This can be
evaporated and carried back to the atmosphere through the
vent system. The small amount of remaining material is
recycled into a useful fertilizing soil.
|
Wherever there is a poorly working septic system, a
SUN-MAR can take care of the toilet waste; where there is
an outhouse we offer the luxury of an indoor facility; and
where there is no toilet at all, a SUN-MAR provides the
right environmental choice. SUN-MAR units are economical,
quick to install and easy to use.
Because no chemicals and no septic systems are used,
fragile environments can be protected. A SUN-MAR
composting unit is 'an environmentally healthy choice for
recycling human waste. The SUN-MAR system produces no
pollutants, while collecting nutrients.

OPERATING A SUN-MAR
Operating a SUN-MAR is easy. Begin by adding
some peat mix (Compost Sure) and some SUN-MAR
"Microbe Mix" to the Bio-drum™ (Both "Compost
Sure" and "Microbe Mix" are
included with all units). Now use your SUN-MAR like
a regular toilet. Toilet paper needs no special
treatment. It is easily decomposed in a SUN-MAR.
For ongoing Maintenance add a cupful of peat mix
at the rate of one cupful per person per day of use. When
in use, rotate the Bio-drum™ 4-6 full revolutions
every third day. For weekend use, just rotate the drum
when you leave at the end of the weekend.
To remove compost, release the drum lock and
rotate the drum backwards. Now, the drum door remains open
and compost drops automatically into the finishing drawer.
The entire process takes under 2 minutes and you never
have to touch fresh material. In cottage use, some
composted material is usually only taken out in the
Spring to make room for next year's operation. In
heavy, or residential use, some compost will need to be
dropped down more often into the drawer for finishing.
|
Excess moisture in the drum drains
automatically through a screen in the rear of the drum
into the evaporating chamber. This chamber forms the entire
floor of the unit. The superb aeration in the
Bio-drum™ ensures an aerobic and therefore odorless
breakdown of the compost.
ODOR FREE
As
well as ensuring an aerobic breakdown in the Bio-drum™,
SUN-MAR ensures an odor free environment by
engineering the air flow within the unit to maintain a partial
vacuum at all times. Air is drawn in by a fan, or on
non-electric units by the vent chimney, over the
evaporating chamber and up the vent stack. Not only does
this evaporate excess liquid, but, by continuously
pulling air in, we ensure no smell escapes from the
unit.
Evaporation is assisted on electric units by a
thermostatically controlled heater in a sealed compartment
underneath the evaporating chamber.

SUN-MAR units are designed for easy Do-it-Yourself
installation. Shipping cartons include (at no extra
cost) everything needed to install and operate the unit.
The only exception is the 3" plumbing pipe and
fittings needed to connect a 1 hint flush toilet to a
central composting unit.
CONTENTS OF SHIPPING CARTON:
• An Owner's Manual (specific to each unit)
• Warranty card
• Peat Mix (301, bag) and dried bacteria 1(1 starting
off the unit
• Rake for periodic clearing of the evaporating chamber
• "Compost Quick" enzyme for speeding Lip
composting
• Complete vent kit including all pipe, fittings and
vent intake assembly.
ALSO INCLUDED:

except EXCEL and COMPACT.
• Evaporating tray for placing under the drum screen on
all Central units.
ELECTRICAL INSTALLATION
All electric units are supplied with a power cord and
pre-molded plug which connects to a standard three(3) pin
115 Volt outlet and powers both the fan and heating
element.

Vent kits for 2" pipe include two 45° and one 90°
elbow in addition to the necessary connectors. 6 ft of
2" pipe insulation is contained in EXCEL and COMPACT
kits.
• AC/DC units have a complete 4" vent kit in
addition to a 2" kit.
• 3" and 4" kits include only connectors,
except that the 4" kits for A/F NE and AC/DC units
have two 450 elbows and a 1.4 Watt 12V fan (2000 series)
or 2.4 Watt 12V fan (3000 series) for installation in the
vent stack.
• Mobile units include 6ft. of 3" flexible tubing,
and a fan box with a 12 Volt 4.0 Watt fan. The installer
should select a suitable deck vent for the particular
installation.
The vent kits included in the shipping carton are
sufficient for installation in most single story
buildings. If more is needed they are normally easy to
find. 2" pipe is PVC Central vacuum tubing, and
3" and 4" pipe is ABS sewer pipe.
Electric units with 2" stacks should have the
minimum number of bends, should use 45° elbows wherever
possible, and should not have bends totaling more than 360°.
No pipe run should be horizontal.
3" ECOLET® and Spacesaver vents and especially
4" Non-electric vent stacks should be installed as
straight as possible. If 45° elbow, are needed in a
4" vent stack then a 12 Volt fan should be included
in the installation.
Installing a 12 volt fan |
Merging a SUN-MAR Vent with other existing vents risks
interference and is not advised.
The diffusor included with all but mobile units is a
simple but effective device originally patented by SUN-MAR
principals to aid updraft, avoid winter freeze up, and
protect the vent from downdraft and weather. As shown in
the drawing they should ideally be installed 20" or
more above the peak, although depending on prevailing
winds, lower installations may be possible.
