TOOLS REQUIRED

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 excess fluids 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 concrete, sand or crusher dust bed.
3. Mark and cut holes in the floor 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.

• 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 floor of the building, the order of the installation can be changed as follows: Firstly, cut the hole for the pedestal in the floor 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 fit 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 packed earth with the tank placed on a base of sand, or a wooden frame on a solid base (e.g. 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 water and floodwater.

FOR BURIED INSTALL SYSTEM ONLY
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 CM14 tank.

TOILET CHUTE & PEDESTAL

• Please refer to the separate pedestal installation manual for instructions on how to locate the pedestal in your bathroom.

< 5mm of sideways play around the hole.

Note: If the floor 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.

• Lift the toilet chute slightly and put sealant between the toilet chute and the floor then press chute down again to seat firmly onto the floor.

• Bend and move the metal edging strip of the chute collar to the tank.

• Run a bead of silicon sealant around the underside edge of the collar.

• Using the 1/2 stainless screw provided, secured the collar of the tank top by screwing through the metal edging strip.

PEDESTAL INSTALLATION

• See separate instruction manual for pedestal installation

INSTALLATION OF VENTILATION SYSTEM
Note: As air flow 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.

• Cut hole 121mm 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 fittings according to building/ roofing instructions. Complexity may vary.

• Mount the mozzie stoppa onto the vent pipe. Use the fan joiner to attach the fan housing onto the mozzie stoppa. Position the fan housing so that it can be easily accessed and secure with silicon.
• NOTE: The fan should run 24 hours a day to continuously circulate air through the compost heap and minimise odour.

• Install the vent cowl or optional turbo vent (1). Secure with 3 self-tapping screws.

• Attach the upper section of the vent pipe. The pipe should be supported against the wall of the building with the brackets provided (2, 3). This configuration will vary depending on location of CM14.

STARTER-BED OF ORGANIC MATTER

NOT SUITABLE BULKING MATERIAL
