The system normally comprises 2 or 3 separate chambers (gravity or pumped system).
The system comprises a pre-treatment chamber (of 3,560 litres) gravity feeding to a
secondary treatment chamber (1,280 litres) incorporating a Zabel A100/300 ilter.
If a pump is incorporated into the system, the pump well has a capacity of 700 litres. Various
pumps can be itted to the system depending on duty requirements.
The system may also be itted with an electrical isolator switch and high water level audible
alarm, mounted on a post on the system, in the event of system malfunction.
INTRODUCTION INTRODUCING
PRODUCTS INTO
THE SYSTEM
Introducing harmful products into the system may reduce the eiciency of the system
or stop the treatment process by destroying the bacteria. These products that reduce
the eiciency or stop the treatment process can be grouped into two groups, prohibited
substances and limited-use substances. While the wastewater treatment system will process
most waste produced by the average household, the following information will maximise the
system’s eiciency and reduce the time period between primary chamber pump-outs.
NOTICE: Introducing harmful or damaging chemicals into your Clearwater Z54 Deluxe System
may void the Warranty.
A. Prohibited Substances:
These substances are detrimental to the system’s ability to process wastewater, even when
present in small amounts. Prohibited substances include but are not limited to the following:
Do not introduce the following prohibited substances into your Clearwater Z54 System:
• Plastic or rubber products, petroleum products, such as motor oil, paint, paint thinner,
petrol and solvents
• Non-biodegradable products, such as sanitary napkins, condoms and disposable
napkins
• Toxic substances such as pesticides, strong disinfectants and strong caustic drain
cleaners
• Large amounts of paper products, such as paper towels and synthetic ibrereinforced
products advertised as having “wet strength”
• Animal fats, such as bacon grease or lard (normal cleaning of pots and pans is
acceptable).

Chemicals
The following chemicals are prohibited substances and should not be poured into the
Treatment System:
• Herbicides
• Pesticides
• Paint
• Thinner
• Motor Oil
Have you read the “Essential Guidelines”?
(enclosed with your system information)
B. Limited-Use Substances:
Limited-Use substances in large concentrations will reduce or stop the treatment process.
The same substances in smaller concentrations will have no harmful eect on the treatment
process. You may use the following substances without harming your Clearwater Z54 Deluxe
Treatment System if you use the substance according to the manufacturer’s directions, use
the substances SPARINGLY, and do not introduce concentrated doses into the system:
• Bio-degradable laundry powders
• Laundry Bleach
• Detergents with Bleach
Household cleaners containing sodium bactericides such as:
• Pine oil (disinfectant used in general purpose liquid cleaners)
• N-alkyl dichlorobenzyl ammonium chloride (disinfectant used in detergents and spray
cleaners)
• Sodium hydroxide (LYE chemical used in drain openers and cleaners)
• Sodium dichlor-s-triazinetrione (powdered bleach used in scouring powders and
automatic dishwasher detergents)
• Ortho-phenylphenol (bactericide used in tub and toilet bowl cleaners)
Waste Food
Some food waste, whether or not it is run through a waste grinder will not be treated by the
system, but will remain in solid form and fall to the bottom of the septic tank. Therefore, you
should consider not using a waste grinder system, or disposing of these food items through
the Clearwater Z54 Deluxe Treatment System:
• Animal Bones
• Melon Rinds
• Corn Cobs
• Pips and Seeds
• Eggshells
• Any other non-edible food waste
C. Acceptable Substances:
Substances that are considered to be typical domestic wastewater are human waste, bath
and dish water and edible food waste.
The following substances may be used regularly without harming your Clearwater Z54
Deluxe Wastewater Treatment System:
• Laundry detergents without bleach
• Dishwashing detergents without bleach
• Toilet Paper
• Household cleaners containing sodium bicarbonate, sodium carbonate and sodium
borate.

SYSTEM
MAINTENANCE,
MONITORING AND
SERVICING
The Clearwater Z54 Deluxe is available as either a gravity fed or dosed pump system. The
owner should determine the status of the system, substances introduced into the system,
and the frequency of required pump-out as determined by the service provider.
Your Clearwater Z54 Deluxe System can be furnished with an annual service policy to ensure
proper operation of the system.
Primary and Secondary Chamber:
Periodically, waste will need to be removed from both chambers using normal pump-out
procedures.
Zabel A100/300 Filter:
The system is compelte with a Zabel bacteriological ilter which performs two primary
functions in a septic tank installation. It retains and ilters 75% of all suspended solids in the
tank and treats the wastewater by lowering the BOD5 more than 50%.
Dosed Pumping System:
A dosed pumping system is used to give a proportioned controlled low to the engineered
designed disposal ield, to allow for even distribution over the entire ield. Submersible
eluent pumps operate in harsh acidic conditions and should be checked on a regular basis
for satisfactory operation.
System Capacity:
The system is rated for a maximum of 810 persons or 1,800 litres per day. As with any system
it is important the system is not hydraulically overloaded as this will interfere with the organic
breakdown of the treatment process.
Visual:
Wastewater backup is characterised by wastewater lowing back into the house or slow
movement of wastewater in the drains. This may indicate a problem with your wastewater
treatment system. Identify where the backup is occurring within your home’s plumbing
system. If no material is blocking the drain, contact you Service Technician or local supplier.

Oasis Z54 tank controller installation guide
Refer to attached wiring and circuit diagram when installing the controller. All electrical work
must be carried out as per NZS 3000:2007 and NZECP2:1993. The controller is to be earthed
at the distribution board and the supply to the controller should be protected by its own
dedicated 16Amp 30mA RCD or as required. Any questions during installation please contact
N2P Controls on 09 570 1919.
This controller is rated to 4A at 230V and has been
designed for the Z54 pumps only.
1. Remove the cover from the controller.
2. Refer to wiring diagram to side. Wire the supply
Earth, Neutral and Phase to the bottom 3 terminals.
3. Wire the pump’s phase, neutral and earth terminals
to the next 3 terminals.
4. Wire the high level alarm loat to the terminals
labelled Alarm NO (Brown Wire) and Alarm NO
(Black Wire). The loat is to be wired Normally Open
(NO). The blue wire is not used and can be wired to
the Alarm Not Used (Blue Wire) terminal. The level
loat is low voltage.
5. NOTE: The ON/OFF switch is to turn power on and
o to the pump and printed circuit board only.
6. Once installed commission by:
• Power controller – Green Power LED light should
illuminate on front.
• Test pump by lifting the loat attached to the
pump.
• Test high level alarm by lifting high level alarm
loat. The red Fault LED should illuminate, buzzer
sound and alarm light lash.
• Press the mute button and the buzzer shall stop.
