MATERIALS REQUIRED
• Water to wet starter material.
• Additional 50mm PVC pipe (coupling and bends if absorption trench is to be located some
distance away from tank). Additional pipe bends if needed for vent pipe.
• In poor soil conditions, extra length of trenching arch or agi drain may be required.
• Drainage gravel for leachate drain.
INSTALLATION SUMMARY
1. Ensure the tank is in a position so that the toilet chute will be perfectly straight over the
tank below.
2. Ensure the tank foundation is solid with a sand or crusher dust bed.
3. Mark and cut holes in the oor for the toilet chute.
4. Mark and cut holes in the tank top.
5. Insert toilet chute and pedestal.
6. Install the vent system.
7. Install the liquid end-product drain pipe and absorption/transpiration trench.
8. Connect fan to power source.
9. Check everything is sealed.
10. Place a starter-bed of suitable bulking agent (e.g. wood shavings) in the unit.
11. Wet bulking agent before use of toilet.
12. Add starter bacteria after 14 days of use.

CONDITIONS
Any decomposition process works better where temperatures are warmer. Over the winter
months the composting process slows or can even temporarily stop where temperatures in the
pile drop below 4°C.
>13°C
Ideal temperature for composting
<13°C
Composting process slows
As the composting tank is black, it will absorb heat from the sun. Simply by installing the
compost bin on the north side of the house will make a dramatic difference to the
composting process. In addition, a translucent hatch and enclosure can be installed around
the compost bin. In extreme alpine conditions it may be necessary to insulate the tank itself in
addition to the above.

POSITIONING THE TANK
If there is very little room between the top of the tank and the oor of the building, the order
of the installation can be changed as follows: Firstly, cut the hole for the pedestal in the oor
of the building (refer to page 11, Toilet Chute & Pedestal). Position the tank under the hole
and then mark the position of the hole onto the tank. After the tank has been marked, it can
be removed from under the building. Cut the hole in the tank and t the chute collar before
placing the tank back into position.
- Check the position planned for the toilet chute. The toilet chute must be positioned over
the top of the compost tank. For less maintenance of the compost pile, the optimum
location for the chute/s to enter the tank is mid-width, in the rear half of the tank. A
clearance of at least 150mm from edge of chute to edge of tank-top is desirable to avoid
rapid build up of the pile against the sides.
- Check there are no major support beams, pipes or electrical wire that are in the way of the
toilet chute.
- Where mains power is to be used, check that a power point has been installed near the
location for the ventilation fan.
- Locate where the excess liquid drainpipe and tench is to go and take this into account
when positioning the tank.
TANK SUPPORT
The composting tank must be supported by either compacted subsoil with the tank placed on
a bed of sand, or a concrete slab. Insulation between the tank and the concrete slab will reduce
heat loss and aid the composting process. NOTE: The tank and enclosure should be protected
from surface and oodwater.

INSTALLATION FOR BURIED ANCHOR

For a buried system it is required to hold the tank down with galvanised rods. These are slid
into the slots provided on both sides and the front of the CM40 tank.

on how to locate the pedestal in
your bathroom.

Note: If the oor of the building is high above
the top of the tank a chute extension piece/s
may be needed. Extra lengths are available from
your supplier. Joints should be screwed with
short self-tapper screws, and sealed with silicon.
If more than 2 chutes are joined then additional
support straps or brackets are needed to support
their weight from the building frame, instead of
hanging only by the top chute.
Using the outside of the toilet
chute as a template, mark and
cut the chute hole into the top
of the tank.

PEDESTAL INSTALLATION
See separate instruction manual for pedestal installation.
INSTALLATION OF VENTILATION SYSTEM
Note: As air ow is essential to the operation of the unit, the fewer bends that are used
when installing the vent system the better.
NOTE: The hole for the vent pipe is best at the side of the
tank
or along the top edge, as far as practical from the nearest
chute entry. Refrain from placing it along the front face as
this can hinder opening of maintenance access.
Plan the vent
pipe layout.
Cut hole 168mm in
diameter (as noted on
the wallace seal).

Tip: Putting the wallace seal in
hot water for 5 minutes can help
when installing the PVC pipe.
Secure pipe ttings according
to building/roong instructions.
Complexity may vary.
Mount the fan housing and Mozzie

the fan housing so that it can be

HOW TO USE THE MAIN LID
Aline the lip of the lid with the
front rib of the Main Top Tank.
Push the lip under the rib and
ensure there is a strong secure t.
Once the lip is secured push the lid
down to its nal position.
Once the lid is in its nal position
use the two wing nuts to secure the
front of the lid.
