• Since aerobic bacteria are responsible for
treating the wastewater, inorganic or non-
rapidly biodegradable materials should not be
put into the plant. Examples of improper items
are: plastic products, rubber products, sanitary
napkins or tampons, washcloths, cigarette
butts, melon seeds, coffee grounds, egg shells,
matches, some food items such as corn husks,
grape vines, etc.
• Do not introduce cooking grease or large
amounts of oil into plant; 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 of 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 toilet.
• Large amounts of harsh chemicals, high
foaming detergents, disinfectants or any
substance that kills bacteria must not be
discharged into the plant.
• The plant will not perform to its fullest
capabilities if volumetric overload is allowed to
occur. This occurs whenever excessive water,
above the designed flow rate, is allowed into
the plant. Excessive water use or leaking
plumbing fixtures may cause this condition.
Hydro-Action
®
Dealers & Certified Technicians
are asked to inform homeowner of these
guidelines. Too often a malfunctioning
treatment unit is due to abuse that can be
avoided with simple education.
2.5: Other than for the mechanical and
structural working of the plant itself, Hydro-
Action
®
is not responsible for the in-field
operation of a plant. The proper operation of
this or any other individual wastewater plant
depends upon proper organic and hydraulic
loading of the plant. We cannot control the
loading and thereby control the amount of
harmful substances that may be discharged into
the plant. Only the users of a plant can control
what enters the unit. Therefore, we provide a
comprehensive owner’s manual that outlines
substances that should be kept out of the plant.
2.6: The Hydro-Action
®
AP-Series must be
installed and maintained according to factory
specifications. No modifications of equipment or
design are allowed. Modification of the plant will
void warranty and invalidate NSF certification of
plant.
2.7: OPS
®
models 50-30 or 50-32 include a
timer, which may need to be reset. The 50-30 is
a 24-hour, and the 50-32 is a micro-dose timer.
See the Technical Manual section of timers in
Appendix 3.
SECTION 3.0: Teflon Diffuser Inspection
3.1: With plant access cover removed, look
through the plant access opening. Inspect
system to insure even flow of diffused bubbles
are coming from each diffuser.
3.2: Locate the Schrader air pressure valve on
the PVC air pump discharge line. Unscrew the
protective cap and connect the quick chuck
pressure gauge. Read and record the pressure.
If the pressure equals or exceeds 3.5 psig, a
high pressure condition exists.
Note: Whenever a high pressure condition
exists in the Hydro-Action
®
diffuser airline
assembly it is usually due to a blockage. This
could be either inside the lines or bacterial
growth on the diffusers themselves.
3.3: To remedy a high pressure condition first
try to pressurize the airline with a high pressure
air compressor. This will displace any bacterial
growth on the diffusers themselves.
3.4: If the pressurizing of the lines does not
improve the pressure condition then the
diffusers may need to be replaced.
Note 2: Diffuser assemblies are normally not
replaced on the newer AP Series with the
Teflon diffusers. Older models will need retro-fit.
