material and may require replacement every 7 to 10 years. When the Bio-COIR media has reduced in
volume by 50%, and the effluent quality fails to meet minimum regulatory requirements, it needs to be
replaced. The open cell foam media is warranted to be free from defect
for 10 years. If the media shows degradation after that time and the efflu-
ent quality fails to meet minimum regulatory requirements, new media
should be added. When replacing either media, make sure to compact it
below the spray nozzle by approximately 4-6 inches to make certain that
the spray nozzles function properly.
3. Remove the spray nozzle by unsnapping the stainless steel spring from
the pipe. Clean any debris and replace them. The spray nozzle piping
can be removed at the unions and cleaned with a bottle brush or water
pressure if needed.
NOTE: If effluent samples are needed, a grab sample can be taken by placing the sample bottle below the
out fall of the recirculation device, being careful not to touch the bottle to any contaminated surface. The
effluent sample should be collected and transported according to the testing facility requirements. Efflu-
ent should be clear with a slight yellow tint and should be free
from odor. Effluent results should be in accordance with NSF
Standard 40 Class 1 requirements, BOD less than 25mg/L and
TSS less than 30mg/L.
Section 7.0 Recirculation Device
1. Check to see if the stainless steel rod is moving up and
down freely. Also, check to see if the ball float is located at
the proper level. When the ball float is at its lowest position,
it should be located equal to or just above the on position of
the timer enable float. (figure 1)
2. Check that the design recirculation rates are maintained by observing the discharge through all five out
falls of the recirculation assembly. Adjust as needed by loosening the quick disconnects and leveling.
TROUBLESHOOTING GUIDE
The AeroCell
®
& Bio-COIR
®
systems will handle all domestic wastewater from your home. By the term
wastewater we are referring to rapidly biodegradable material. To keep maintenance at a minimum level
and to prevent the system from malfunctioning, the following guidelines need to be followed:
* Since aerobic bacteria are responsible for treating the wastewater, inorganic or non-rapidly biodegrad-
able materials should not be put into the system. Examples of improper items are: plastic products,
rubber products, sanitary napkins or tampons, washcloths, cigarette butts, coffee grounds, eggshells,
matches, or other non-biodegradable objects.
* Do not dispose of cooking grease or large amounts of oil into system; instead pour it into a container
and dispose of it properly.
* To minimize pump-out frequency, limit use of garbage disposals.
* Lint from lint catchers, hair, etc., should be disposed in the trash and not washed down the drain.
* Water softener backwash should not be routed through the system. Another source of disposal should
be used.
* Diapers can be rinsed out in the toilet; however, do not flush cloth or disposable diapers down the toi-
let.
* Large amounts of harsh chemicals, high sudsing detergents, disinfectants or any substance that kills bac-
teria must not be discharged into the system.
