Inspection

Inspect for Damage
Remove "CENTREX" carefully from carton. If the product has been damaged, contact Sun-Mar to determine best course of action, and :

i) Note damage description on the shipping papers.

ii) If shipper has left, report the damage immediately to the transport company.

Product.

Check that carton and composting drum contain the vent stack (pipe, fittings, roof flashing and diffusor); peat moss, and rake.

i) Turn drum handle clockwise to rotate Bio-drumTM for mixing and aeration (Drum rotates counter-clockwise).

ii) Remove access door and depress drum stopper, while turning drum handle anti- clockwise to simulate extraction of compost. (Bio-drumTM rotates clockwise and drum door remains open).

iii) Plug unit electrical cord into standard electrical outlet, and feel air movement from the vent outlet at top left of the unit to ensure the vent system is working properly.

iv) Pull out compost finishing drawer (at bottom right of the unit) where the compost drops for finishing.

v) After the unit has been plugged in for five minutes, place hand on the floor of the evaporating chamber (underneath where the drawer was) to check it is warm to the hand, and the heater and thermostat are functioning properly.

 

Space Required
The center of the 3" waste pipe needs to be more than 10¼"(26 cm) from the rear wall (if a Sealand is being installed) and 8" (20.5 cm) from the side.

Other Considerations
The Sealand is mounted on a 4 hole floor flange (not supplied) while the Aquamagic requires a 2 hole flange. A 2 hole floor flange can be converted to a 4 hole by drilling two extra holes in the flange to line up with the toilet's mounting bolts.

A Universal Mounting Kit (available from Sun-Mar) can be used to adapt an existing 2 hole floor flange to a 4 hole installation.

Complete toilet installation instructions are included with each toilet.

Installation Considerations
When installing the waste piping from the toilet to the composting unit, the following considerations should be kept in mind:

i) The piping should be either 45 os or more to the vertical, or at a 2-3 o angle so that the waste travels with the liquid.

ii) Piping should not slope upwards at any point.

iii) Connections should be snug so that waste is not encouraged to `hang up' where pipe meets connector.

iv) If the horizontal travel is longer than 15-20 feet, a clear-out port (a Y fitting with screw on end cap) could be installed to provide easy access should it ever be required.

v) Use a soft sealant for the connection of the waste piping to the composting unit so that the composting unit can be moved for servicing or other reasons should this ever be required.

vi) Insulate piping if unit is to be used during the winter. (For heavy winter use, the composting unit will need to be kept warm by enclosing it, insulating the enclosure, and installing one or two light bulbs within. The enclosure must not be airtight since the unit must be able to draw air in. The fan can be turned down by installing a speed control.)

Location of Piping
Piping can be installed up the inside wall, through the wall and up the outside wall, or up inside the wall. The choice depends on ease of installation, visibility, and, (especially if the unit is to be used consistently through a cold winter), the need to keep all exposed vent piping insulated.

Piping Installation
Piping and fittings are of standard 2" vacuum pipe. Additional pipe or fittings are readily available should you need them.

Because each installation is different we make the following general recommendations:-

i) Minimize the number of sharp angles because each reduces vent efficiency. Do not use more than three 90 o elbows, and try and use 45 o elbows wherever possible.

ii) Do not lead the vent pipe downwards at any point because this may lead to the vent pipe being blocked by condensate.

iii) Use a soft sealant for the connection of the vent stack to the composting unit because at some time the unit may have to be moved or you may have to access the fan.

iv) All piping which is subject to freezing temperatures should be insulated with standard foam insulation if the toilet is to be used through the winter.

Leading the Vent Stack Through the Roof
The vent stack should end 2 feet or more above the roof line so that it is less subject to air turbulence and downdraft. Where the piping is taken through the roof, the roof flashing and caulking provided may be used to seal the installation. Where a new roof is being installed, the roof flashing should be laid underneath the new roofing material.
The Diffusor
The diffusor provided with the unit is a simple device to be installed at the top of the vent stack. The diffusor design encourages updraft, and discourages wind and weather from going down the vent stack. Unlike the diffusor, wind turbines may have a tendency to freeze up in winter.

Overflow Drain
The 1" overflow drain at the side of the "CENTREX" exits to both front and back. A hose should be connected to either front or back exit of the drain, and be led to an approved drain facility. The unused exit of the drain should be capped. (Hose, connector, and cap are all included with the unit).
Rain Cover
If the unit sticks out from under the house, or is installed to the side of the house, a roof or cover should be constructed to protect the electrical components from rain.
