Whether you are storing,
transporting or distributing
water or wastewater,
RXP has the solution for
you, with manufacturing
facilities New Zealand wide
and a selection of strong
supporting brands.

OUR
SOLUTION
Thank you for installing an AirTech™ aerated wastewater treatment system.
The AirTech™ system is an efficient, lightweight sewage treatment plant that
safely and effectively processes your disposables and wastewater. The unit
recycles it as clear, odourless nutrient enriched water, that can be safely
discharge into disposable field.
For the environmentally minded this means that the sewage and wastewater is treated
on the property where it's produced and then recycled for reuse with little
environmental impact on the land.
So welcome to your new wastewater system. It will give you years of reliable service. It
is backed and supported by our network of independently trained and approved
installation and service technicians.
Our independent and friendly expert technicians have extensive product and system
knowledge and are happy to take your call to provide support wherever you are. It is all
part of our commitment to your total satisfaction and peace of mind.
The AirTech™ system has been designed recognising the industry's latest Australia/
New Zealand joint standard 1546 Part 1 septic tanks –1547 onsite Wastewater
Management and A.R.C TP 58. It is local body approved and has been through, and
passed all on-site Effluent Treatment National Testing Program (OSET NTP).
The AirTech™ system meets World Health Organisation (WHO) effluent quality
standards.
The AirTech™ is a tough, robust and effective domestic wastewater system and has
been designed by New Zealanders for New Zealand conditions. The design utilises
innovative sewage treatment technology and together with modern rotomoulding
manufacturing processes at our factories in Ashburton and Hamilton, we can deliver a
reliable and efficient wastewater system to you.

Holiday precautions
If you are away for more than six weeks please contact your service supplier so they can monitor your system.
When you return you will get a smell from the system. Once in use and wastewater is coming in, the micro
organisms will populate and smell will disappear. If it continues to smell, call your service supplier.
How does it work?
Ask your installer to explain the workings of the system during the commissioning of the system.
The AirTech™ system has been designed to include
a simple owner service programme carried out at six month intervals (depending on usage).
The service requirements of the system should be carried out by an independent, approved or qualified
service technician.
Following and understanding the instructions in this manual will ensure long term trouble free performance of
the AirTech™ system.
1. Primary septic chamber (anaerobic digestion)
This is the main chamber where all household sewage
and wastewater is discharged and the settling out of up
to 95% of solid waste occurs. There is also a reduction in
the biochemical oxygen demand (bod5) of up to 40%.
The primary chamber has a large liquid working capacity
ensuring maximum retention time allowing anaerobic
digestion of the accumulated solid waste.
he primary chamber is a sealed chamber ensuring
there is no cross flow contamination between the
separate treatment processes within the system. The
outlet is fitted with an industry proven 3mm biow filter
minimising solid waste carry-over integrating a flow
modulation baffle to manage peak flow levels limiting
shock loading of the system.
2. Aeration chamber (aggressive aerobic digestion)
The partially treated wastewater flows into the aeration chamber where aggressive digesting aerobic bacteria can
further reduce the suspended solid sludge. Efficient oxygen transfer through fine air diffusion maintains high aerobic
activity and population. Increased surface area through additional submerged media enhances and accommodates
a greater growth of bacteria.
3. Clarification chamber (dormant settling of suspended solids and sludges)
Wastewater effluent is gravity fed into the clarification chamber where, in quiescent conditions, any remaining
sludge and suspended material settle and are returned to the primary chamber through a venturi airlift manifold.
Sludge is returned by a tap timer once a day.
4. Irrigation pump chamber
The gravity flow of clean, clear, odourless effluent into the irrigation pump chamber is nutrient enriched and is
recycled through a designed irrigation field to enhance landscape on your property.
This chamber is protected with an alarm that will activate in the event of a pump failure, and has a large capacity
effluent storage.
5. Blower box (housing for Air Blower and Electronics)
This houses all of the electronic connections (including the alarm set and sludge return timer), required for
the AirTechTM system. Connection from the house
is terminated on the outside of this box. The blower provides all of the air required for the aerobic digestion of your
waste and must constantly run to achieve best results.

SYSTEM & PROCESS
Not to scale.

Your home has a modern waste water treatment
plant.
This plant treats your household waste water to a high
quality and requires bacteria (bugs), to break down
the waste matter. The wrong products going down
your drains will kill the bugs and the system will not
operate correctly.
Do not turn the power off to the AirTech™ advanced
septic tank system (unless you are rinsing your
external filter) the bacteria will die and the system will
smell.
Items not to be
flushed down drains
- No bleaches or chlorine (i.e. Napisan, Bleach)
These products are designed to kill bugs and will
kill off the bacteria in the tank causing smells and
constant blocking of the Bio (internal) filter. You
can use these products if used in a bucket and tip
on the lawn or safe place, not down your drain
- No fats or oils
Fats and oils may block the tank filters and kill the
bacteria in the tank
- No tea leaves or coffee grounds
These may block the filters in the tank and the
external filter
- No washing paint brushes or disposing of paints
These products will not only kill bacteria in the
tank, but the residue is very difficult and costly to
remove
- No disposable nappies, sanitary napkins, tampons
or condoms
These products do not break down and cause
a mass build up in the tank, which can cause
blockages that can be costly to clean
- Do not have a waste disposal unit
This waste takes a long time to break down and
the system will require frequent emptying which
is very costly
- Use low sudsing laundry powder/liquid and
non-caustic dish washing powder
- Heavy antibiotics, also kill off the bugs. (after the
medication is complete the system will return to
normal).
Other household items not
to be flushed
- Cat litter, kitty litter
- Clothes dryer sheets
- Baby-wipes
- Antibiotics, medicines
- Hair
- Liquor
- Paper towels
- Photo chemicals
- Swimming pool
chemicals
- Washing machine lint
- Cigarettes, butts and
filters
Suitable products to
use
Please note: all products should be used in
moderation. This list is a suggestion only as there are
other products available not listed. Liquid laundry
detergents are better suited to septic and waste
treatment systems than powder laundry detergents
(powder fillers are used in power laundry detergents).
- Dish washing liquids (Ecostore Dishwash Liquid,
Morning Fresh, Palmolive, Sunlight)
- Surface cleaners (Ecostore spray cleaners, Nifty,
Swipe, H7, Jiff Cream Cleanser, Shower Power,
Windex, Bio Zyme, Spray and Wipe (limited
quantity)
- Dish wash powders ( Ecostore Auto Dishwash
Powder)
- Toilet cleaners (Ecostore Toilet Cleaner, H7, Jif
Cream Cleanser)
- Clothes washing powders (Ecostore Laundry
Powder, Cold Power liquid and concentrate,
Ecostore Oxygen Whitener (soaking), EarthOn)
The above list is not intended to promote or discredit
the product of any company. It is provided to assist in
ensuring the correct operation of your waste water
treatment system.

GUIDELINES FOR
YOUR AIRTECH
- On reflection if you won't eat it, don't flush it

How to clean it?
1. Always wear rubber gloves when cleaning your filter
2. First switch your system off at the power source to prevent pump out
3. To remove the cartridge, hold the bottom of the casing and screw the collar anticlockwise to undo (hold
pipes when doing this, to prevent pipes from breaking)
4. Rotating the disc cartridge for a minute or two under the garden hose is usually sufficient to clean all the
silty residue off the filter (to keep the discs spinning well)
5. Put the cartridge back in the casing and screw back on – hand tight only
6. Remember to switch the power to the system back on!
High Water alarm
When the High-Water alarm activates, it is usually
because the filter is blocked. The filter should be cleaned
immediately the alarm activates, as your pump will be
continuously trying to pump water out and cannot. This
will cause undue stress, and will possibly shorten the life
of the pump.
If you clean the filter and the alarm does not go off after
half an hour or so, please ring your installer or service
agent as there may be a problem with the pump

CLEANING YOUR
FILTER
Filter cleaning
Although your waste water system is serviced on a regular basis, there is one crucial task that you as the
occupants of the house should schedule, as part of your regular home maintenance.
The outlet filter on your waster water system must be cleaned regularly to reduce the stress on your pump, and it
helps keep your power bill down too. We recommend cleaning the filter once a month (1st of each month, so that
it is easy to remember), and the filter is kept squeaky clean.
Most modern systems have a filter that looks like, or is similar to this:

Troubleshooting
10 | AirTechTM 9000 Maunal
RX Plastics

• What does the alarm do?
The alarm system doesn’t run the AirTech™ system, it is
an audible and visual alarm to alert the homeowner of
possible issues with the system
• My septic tank is starting to smell, what do I do?
Your systems anaerobic bacteria has died or is dying –
check the points in the guidelines section (pages 6 & 7) of
this manual. If you are still not happy with the results, please
consult your independent service supplier for assistance
• My septic tank is overflowing, what do I do?
Either the internal/external filter is blocked and needs
cleaning, the power is off, or the pump has failed. Firstly,
check that the power is turned on to your system, if it is,
check to see if the internal or outlet filter is blocked and
needs cleaning. If the pump has failed, call your
independent service agent/installer for assistance
• Will reception be reduced if trees or walls are in
between the AirTechTM and LCD unit?
Any wireless system will have range and reception reduced
by obstacles. Similar to the poor reception of radio stations in
valleys and near power lines. It is recommended to minimise
obstructions in the direct path of the wireless signal. Metal
clad walls will cause a drop in signal and use of an external
aerial should be considered if tank is downhill of house.
• What happens if there is a power cut or the power to
the LCD is interrupted?
Once power is restored the LCD unit will communicate
with the tank and previous readings/data will be restored
to the screen automatically. No data will be lost and you
will not need to re-connect the LCD to the AirTech™ unit.
If power is lost to the outside tank unit an alarm will sound
only after 3 hrs, alerting the home owner to this signal loss
as (septic 1 not reporting). If an electrical strike has
occurred it is possible for the LCD screen to revert to it’s
original state of a water tank monitor the picture of an
empty water beaker will be displayed in this instance a
reset and repairing will be required.
Frequently asked
questions:
General do’s and don’ts
- Don’t turn your system off
- Do call your supplier when you encounter a
problem
- We recommend that you do your washing up on a
daily basis so as not to shock load the system
- Try to avoid using showers, washing machines,
dishwashers etc. all at the same time
- Don’t try to service the system yourself as
there are health risks to consider and you may
compromise your warranty
- Do use common sense, adhering to the basic
rules provided throughout this manual will ensure
a trouble free, and cost effective system
Suitable plants for
Evapo-transpiration systems
Evapo-transpiration systems employ the combined
effects of evaporation from soil and transpiration
from plants to dispose of wastewater effluent to the
atmosphere. Moisture is wicked up to plant roots and
to the soil surface. The plants use the moisture in their
growing processes and subsequently transpire the
excess through their leaves to the atmosphere.

FEATURES
The screen will indicate the fault, either as:
AHigh Water Alarm which can mean that your
irrigation filter is blocked and needs cleaning, or that you
have a problem with your irrigation pump. Please
contact your independent service supplier/ installer
B Aeration fault, which can mean that your aeration
blower is not working or blowing enough air. Please call your service supplier/installer.
On pressing the FAULT this will silence the buzzer for 24 hours only. Once 24 hrs are up the alarm will again activate
reminding the homeowner of the FAULT
Once the system is fixed or corrects itself after a power interrupt the system will revert to NORMAL use
Every 6 months from a Service due

Servicing includes
1. A general inspection of tank area, irrigation and
drainage
2. Cleaning internal bio filter and external filter
3. Inspection of all chambers for correct operation
and usage
4. Checking air blower, submersible pump switch and
alarm operation
5. Checking sludge return and adjusting if necessary
6. Ensuring all lids are secure before leaving area
Note: As with any septic tank, the primary tank will
need to be de-sludged (pumped out) every three to
nine years. Service Agent needs to test for sludge
build up at every service, and if the sludge is greater
than a 30% of the volume of the tank the tank will
need to be pumped out.
- The cost of de-sludging is the home owner's
responsibility
- Never pump out in wet weather as flotation may
occur
Warranty
The AirTech™ aerated wastewater treatment unit is covered by the RXP extended warranty and overs all
polyethylene rotomoulded tanks to be free of defects in workmanship and materials for a period of 15 years.
NOTE: The electrical componentry, including the alarm, is covered by a two year warranty only. The

Servicing
Arrangements
Your AirTech™ aerated waste water treatment system requires service and maintenance inspections every
six months for continuity of warranty. RXP recommends the system be serviced every six months, by trained
independent service agents/installers. This is a warranty requirement.
Your system alarm set will notify you every six months for you to arrange a suitable time to attend to your
AirTech™ system servicing needs.
Arrange with your service supplier to give you a report on every service. You need to hold onto these for 10
years. You can record services and repairs in this manual.
Please call your installer/service supplier for servicing costs in your area. Servicing is usually carried out every
six months, unless heavy usage occurs, during holiday periods for example, where your system may need to
be serviced sooner. If you have any failures, please call agent and reduce water usage until issue has been
resolved.
Your responsibility
As the owner of the system you are responsible
for the correct operation and maintenance and to conform to regional and local council requirements as set
out in your discharge permit/resource consent.
Council requirements
Now that your AirTech™ system has been installed
there are a few council regulations that you must
adhere to:
- Irrigated water must not be allowed to run off onto
other properties or into waterways
- No fruit or vegetables grown on your property
are to be irrigated with effluent from the system.
The irrigated water is to be used only for irrigation
purposes. It is not suitable for human or animal
consumption
- To avoid confusion, use only the purple coloured
drip line as this identifies waste water
- The council must approve that the area being
landscaped or planted is to their standards
- All storm water and groundwater seepage should
be diverted around the disposal and tank areas to
avoid entering the system and irrigation area
