1) To facilitate maintenance and compost emoval, ensu e that the e is at least 17” in f ont of the
CENTREX 3000, fo emoval of the d awe and access panel.
2) The safety d ain is necessa y fo ALL installations. Install the unit in a location whe e the
safety d ain can be connected. This d ain exits f om the left side of the unit and must slope
downwa d at all points.
3) Install in a location whe e the vent pipe can be attached as pe the inst uctions listed below.
4) Install in a location that is not ai tight. The toilet must be able to vent to ensu e odo f ee
ope ation.
5) Ensu e that the CENTREX 3000 NE is accessible fo ongoing maintenance.
6) Ensu e that the installation a ea is a minimum of 28” in height. WE DO NOT RECOMMEND
DIGGING BELOW GROUND TO FACILITATE THE INSTALLATION OF THE CENTREX
3000.
7) Bends in the vent, installation nea hills o ove hanging t ees may cause down d aft. A 12 volt
fan may be necessa y.
8) Competing appliances (ie. wood stove) may equi e an ai intake installed f om the outdoo s if
the unit is installed in an enclosed basement. A 12 volt fan may be equi ed.
9) Ensu e that the unit is installed on a level su face o sloping slightly towa ds the safety d ain.
1) All vent should be ve tically installed.
2) Limit bends in the vent stack to no mo e than 2 - 45 ° bends.
NO HORIZONTAL SECTIONS OF VENT.
3) INSTALL VENT SO THAT IT TERMINATES 24” - 30”
ABOVE HIGHEST PEAK OF THE ROOF. If the vent is being
installed on a steeply pitched oof whe e snow shea may
occu ; Install a heavie pipe th ough the oof and feed the
enclosed vent th ough the heavie pipe. Seal between the
pipes with expanding foam o othe such wate -tight mate ial.
The heavie pipe should be able to withstand the weight of
sliding snow.
4) If the e is mo e than 36” of vent needed above the oof line
to each 24-30” above the highest peak of the oof (diffuso
included in measu ement), use guy wi es to secu e the vent
above the oof.
5) The vent must be installed sepa ately f om ALL othe
household vents. Venting cannot be me ged with othe
venting. Doing so will p event the unit f om ope ating
odo lessly.
6) All connecto s in the vent pipe should be sealed. Use
silicone caulking to seal the connections.
7) The diffuso should be glued ve tically on to the top of the
vent pipe. This assembly helps d aw ai up the vent pipe.
Place the vent inlet coupling into the hole on the top of the unit
fo the 4” vent and so that the 1” of smalle diamete pipe is
p ot uding into the hole. This is the fi st piece of the venting.
Once you have finished assembling the vent, un a bead of
silicone a ound whe e the inlet coupling meets the top of the
composting unit to p event odo f om escaping.
Install the 12 volt fan on the inlet coupling with the la ge side
with the wi es p ot uding facing upwa ds (as shown in the
pictu e at ight). When the 12 volt fan is tu ned off, it fo ms an
obst uction in the vent, and should the efo e un continuously
while the cottage o home is occupied. An optional switch (as
small as 1 amp) may be installed, and the fan tu ned off when
the toilet will not be used fo seve al weeks. The ed wi e
should be connected to the positive (+) te minal on you batte y
o DC system, and the blue wi e to the negative te minal (-).
The 12 volt fan may be powe ed with a batte y that is
connected to a gene ato , sola panel, o othe alte native
ene gy system.
