OPERATION
(depends on installation chosen)
Single Button operation -
Both toilet and electro scan are operated by one of the
following options:
Option #1: System status panel Touch Pad
"Start/Stop" button activates both the toilet and
treatment cycle.
Note: Toilet flush time is factory pre-set for 10
seconds and is adjustable, see "setting toilet flush
time"
Option #2: Toilet Push Button -
Flushing toilet will activate treatment cycle. Flush
toilet as often as necessary until system status
green light begins to blink.
Independent Button operation -
Used with manual flush toilets or if Electric toilet is
being activated seperately from Electroscan. "Start/
Stop" button must be pressed before toilet is flushed.
Flush toilet as often as necessary until system status
green light begins to blink 35 seconds after activa-
tion.
To Stop Treatment Cycle -
Pressing "Start/Stop" again stops the treatment cycle,
If wired per option #1 it will also stop the toilet from
flushing.
Notes:
1) Total flush volume must not exceed 1.5 gallons
(5.7 liters) per cycle.
2) Operating with red light for extended periods
will damage electrode and void warranty
How it works -
Each time the toilet is flushed an equal amount of previ-
ously treated waste is discharged. The electro scan does not
pump waste out. The flushing action of the toilet moves the
waste through the electro scan.
The first chamber macerates to reduce particle size. The
second chamber mixes to ensure uniform treatment of
contents. When the tank is full with salt water the electrode
plates, when electricity is applied, generate bactericide in
both chambers.
When first activated both motors come on and run for the
entire cycle. The user then has 35 seconds to flush toilet.
After 35 seconds the electrode is energized to begin the
treatment process which lasts for approximately 2 minutes.
Note: If the green light is not flashing during treat-
ment, the cycle has been automatically extended to
ensure proper treatment. The unit MUST not be
operated in extended cycle for long periods as damage
to electrodes will occur. Immediately attempt to
determine the cause and fix a red light condition.
