Pull finishing drawer out and put your hand
in the evaporation 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 commonly the
thermostat that has failed. If you notice a
lack of evaporation, but there is still warmth
in the heating chamber, see “Liquid Build
up” 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 electric box is
moist or discolored, or heating does not
work after the new thermostat has been
connected, 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) Check fuse located on
the electric box to ensure that it is
functioning correctly, if the wire in the fuse
is charred or broken, replace the fuse.
Remove the finishing drawer. The drum
screen is located on the bottom of the
patented Bio-drum, to the left of the drawer
opening. Scrub drum screen with a wire
brush.
Drill out set screw and replace, or have
your serial number ready and call SUN-
MAR for a handle replacement kit
(instructions included).
Have your serial number ready and call
SUN-MAR for a replacement small gear kit.
Spray hinges with Compost Quick. Scrub
hinges with toothbrush or other soft nylon
bristled brush.
A ground fault interrupter
circuit is recommended to
protect your CENTREX
1000 Toilet from power
surges that could cause
your heating 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.
If you ever remove the unit
for cleaning, DO NOT use a
water hose around the base
of the unit.
Power surges can cause
the fuse to blow. If this is a
possibility in your area, a
surge protector is re-
commended.
Scrub drum screen with a
wire brush.
Drum should never be more
than ½ full.
