Increased usage.
Failure of heating

Mineral salts may

Have your serial number ready and call Sun-Mar.
The amount of liquid varies substantially between
installations. The overflow drain needs to be
installed on all Centrex 3000 AC/DC with low-flush
toilets.
Check “heating not working
To get rid of these, fill the evaporation chamber
with very hot water and 1/3 bottle of “Compost
Quick” enzyme liquid. Leave overnight. Drain all
Liquid through the overflow drain by tipping the
unit up (make sure overflow is hooked up first)
Connect overflow safety drain (See also increased
usage above) Check and ensure that the unit is
level or tilting slightly towards the left by placing
a 1/4” - 1/2” (6-12mm) shim piece under the
right side of the unit.
1. Rake peat moss away from left two corners
of Centrex 3000 These are the
“buildup” areas. If drains are still clogged,
proceed to step 3.
2. Check drain line for kinks, blockages or
upward bends. Remove and flush if blockages
present, unkink if bent and ensure that the
drain pipe is sloping downward. If your
drain pipe is in order, proceed to step 3.
3. Use a wire to poke peat moss out of the drain
assembly at the back. You will notice if this
is clogged because you will see a brown spot
through the opaque assembly. (Only peat
would make it through the drum screen). If
there is no peat clog, or the problems contin-
ue, backwash the unit quickly with a hose by
applying the nozzle to one of the drain
assemblies and turning it on and off very
quickly. If the bottom of the unit is full of
liquid, you may wish to remove some prior to
back-washing. A shop-vac works well.
The fan is a continuously moving
part which will eventually have to be
changed. Do Not turn on and off
daily.
Install the overflow drain.
Rake evaporating chamber vigor-
ously at spring startups for cottage
use, and once every other month
for residential use.
1. A clogged drain is not very likely
to happen if you rake your
evaporating chamber 1-2 times a
season (cottage use) and 3-4
times for continuous use.
2. Use premium 1” hose for the
drain line. A good hose will be
less likely to kink. Use elbows or
fittings around bends to prevent
kinks.
3. Use Compost Sure as your bulk-
ing material.
