Chapter 1
Inspection
This chapter describes how to inspect your new Centrex 3000 prior to installation for damage and make
sure you have received all of the parts.
Check for
Damage
Check Carton
Contents
and
Familiarize
Yourself with
the
Centrex 3000
Placement of
Unit
i)
If there is any visible damage to the carton
-
the contents of carton MUST be inspected before signing bill of lading. Damaged units
should be refused. Call Sun-Mar immediately.
ii)
Before signing the shipping papers and dismissing the driver.
-
ensure that the carton contents have been inspected.
iii)
If the shipper has left
-
Report the damage immediately to the transport company and call Sun-Mar.
iv)
Soon after delivery, remove the Centrex 3000 carefully
from the carton
-
If there is hidden damage, or for any service Questions, contact Sun-Mar to determine
the best course of action.
Check that the carton contains the vent stack (pipe, fittings, roof flashing and diffusor);
“Compost Sure”, rake, drain hose and fittings, etc. Notify Sun-Mar if you are missing anything.
i) Turn the drum handle clockwise to rotate the Bio-Drum for mixing and aeration. (The drum
rotates counter-clockwise and the drum door closes). TThhiiss iiss hhooww yyoouu wwiillll rroottaattee tthhee ddrruum

ii) Lift and remove the access door and rotate the drum until the drum opening is opposite
the access door for adding “Compost Sure Blue”. TThhiiss iiss hhooww yyoouu wwiillll aadddd ““CCoom

iii) Plug the unit’s electrical cord into a standard three-prong electrical outlet, and feel the air
movement from the vent outlet at the top left of the unit to ensure the vent system is
working properly.
v) Pull out the compost finishing drawers at the bottom left and right of the unit.
vi) After the unit has been plugged in for ten minutes(Electric and AC/DC units) , place a hand
on the floor of the evaporating chamber (the inside floor of the unit) to check it is warm
to the touch, and that the heater is working properly.
vii) Affix the “WARNING/CLEANING” sticker to the underside of the toilet seat cover, and check
that another is on the access port of the composting unit.
The unit should be installed so that the base is protected from weather. The rubber “u” chan-
nel at the bottom of the unit is well-sealed with silicone, but if the unit is sitting in water, has
snow melting against it, or rain pouring on it, this may eventually wear through and short out
the heating element. Install your unit with a protective cover of some kind around this area,
and do not install the unit in a pit where water can accumulate around it.

Pull drawer out and put your hand in the evapo-
ration chamber (Not in the liquid). If there is no
warmth rising from the floor of the unit, your
heating system is not working. It is most com-
monly the thermostat that has failed. If you
notice a lack of evaporation, but there is still
warmth in the heating chamber, see “Liquid
Buildup” for solutions.
Have your serial number ready and call Sun-Mar
for a replacement. (Detailed instructions are
included with the replacement part)
If the insulation behind the thermostat access
cover is moist or discolored, or heating does not
work after the new thermostat has been connect-
ed, then the heating element has failed.
Have your serial number ready and call Sun-Mar
for a replacement. (Detailed instructions are
included with the replacement part)
Please note: Because this part is not easy to
replace, and because there is far less chance
that you will need this part than a thermostat; we
recommend trying to replace the thermostat first.
Remove the finishing drawer. By reaching
through the opening to the right, you should be
able to access the drum screen. Scrub vigorous-
ly with a wire brush.
Use a 1/4” to 1/2” (6-13mm)wedge piece under
the right side of the unit to drain liquid more eas-
ily towards the overflow drain of the unit.
Have serial number ready and call Sun-Mar for a
replacement part.
A ground fault interrupter circuit is
recommended to protect your
Centrex 3000 AC/DC from power
surges that could cause your heat-
ing system to malfunction.
Your thermostat and fan are the two
constantly moving parts on the unit,
and so are the most likely to fail.
Both are easy to replace.
DO NOT wash the outside of the unit
with a hose or pressure washer.
Install the unit so that ground water
or weather cannot get at the base of
the unit.
When returning the drum to top dead
center position, do not bang against
drum locker with excessive force.
