1CHEMICAL GUIDE
Oxiswim Support Chemicals
When operating the system chlorine-free, the following chemicals are recommended:
•Perox Pro –Hydrogen peroxide designed explicitly for use in a swimming pool
•Perox Safe & Clear –Needed to generate chlorine dioxide from Oxiswim Sanitiser
•Perox Activate –Used to break down and remove body fats, oils, sun tan lotions, and
makeup. Prevents scum build-up around the water line and prevents and removes
biofilms.
•Perox pH Control - Hybrid acid that is non-fuming, does not need to be diluted,
removes phosphates, clarifies the water, and will help prevent algae.
Safe to use with a chemical dosing system
•Perox Start-Up - Protects the surface of your pool and pipework from calcium
deposits reducing the consumption of hydrogen peroxide and chlorine
•Aqua~Health Concide / Aquachlor Long Life Algaecide -Activates hydrogen
peroxide in the pool water and helps prevent algae growth
•Perox Perfect - Used for green pool recovery or phosphate removal
•C5 Tablets - Prevents formation of biofilm and will reduce consumption of hydrogen
peroxide and chlorine
Filter Cleaners:
•Aqua~Health Natural Filter Cleaner or similar cartridge filter cleaner may also be
used
When running chlorine, you can continue to use the above support chemicals in conjunction
with liquid, powdered chlorine, or chlorine produced by a salt chlorinator.
Perox Pro is not used when running chlorine.
Do not use any polyquats or lanthanum chloride-based products at any time while using this
system.

2INTRODUCTION
The Oxiswim Sanitisation system is a revolution in how a swimming pool owner can run
their swimming pool or spa. The system has been developed as a result of many years of
research using alternatives to chlorine whilst offering the cost savings of being able to use
chlorine if desired. When operating the pool using Perox Sanitisers at the recommended
level, chlorine cannot co-exist in the water - even if added at very low dosage rates. Chlorine
can only become the dominant sanitiser when all Hydrogen Peroxide has been consumed in
the pool water. When operating using Hydrogen Peroxide, it's free of odours and taste and
is soft and gentle on the skin. What's more, no shower is required after swimming. It's been
described by users as "just like a refreshing swim in a natural spring".
The Oxiswim system uses new catalytic technology that removes the need to use ozone.
However, the advanced oxidation process continues to be the cornerstone of the system
when operating on hydrogen peroxide. Using the advanced oxidation process is a chemical
reaction generated by combining Perox (a chlorine-free, hydrogen peroxide-based sanitiser)
and a catalytic material that will remove bacterial threats better than any other oxidation
process.
NOTE
The Oxiswim system is a kit of components. Attempting to operate the system
without correctly installing all parts or with chemicals other than those
recommended in this manual may result in the system not functioning
correctly, and failure of the system may be hazarous or may cause adverse
effects to your swimming pool or bathers.
Do not use chemicals other than those recommended in this manual
Gloves and safety glasses should be worn when handling chemicals.

PLEASE NOTE: The above information is a guide only. Please refer to the local laws that
govern a swimming pool or spa operation in your area. Always operate the system in
compliance with local laws.
IMPORTANT: When refilling a pool, use municipal or tank water only. It is not
recommended that Bore or Well water is used to fill or top up a pool unless it has been
tested and recommended for this purpose.

OXISWIM MANUAL
P a g e 14 | 45
5.2 Phosphate Treatment
If Phosphate levels are higher than 1.0ppm, then;
Treat the high phosphate levels as an event, and complete a shock dose treatment using
Perox Perfect once the system has been commissioned.
There should be no need to treat phosphates regularly with any other chemicals other than
Perox Perfect, provided Perox pH control is used to control the pH.
Diatomaceous Earth filters are not recommended for use with Hydrogen Peroxide.
Copper ionisers can be used in conjunction with the Oxiswim system, but total copper levels
must not exceed 1ppm.
5.3 Planning
Before commencing the installation, take time to plan;
•That the chemical drums will be at least 1.5m (5 ft.) apart.
•Ensure the unit is protected from the weather and, when possible, not exposed to
elements.

ENSURE THE POWER TO THE SYSTEM AND GPO's OFF AT THIS POINT
6.1 Install the Controller Panel
6.1.1 Install the wall-mounted panel, ensuring that the POWER supply is OFF
6.1.2 Plug the pool pump into the GPO outlet marked 'PUMP', ensuring the POWER is
OFF at the GPO.
6.1.3 Install the Hydroxyl Radical Generator as per the diagram on the inlet side of the
filter. For additional information regarding the Hydroxyl Radical Generator, please
refer to the instruction manual located in the box that contains the Hydroxyl
Radical Generator.
6.1.4 Connect the chemical dosing tubes as per the diagram. Use blue tube for acid and
yellow tube for hydrogen peroxide/chlorine. Use the tapping saddle provided to
connect the acid feed in an appropriate position based on the installation
diagram. Refer to 6.2 for instructions on how to install a tapping saddle.
Refer to 6.3 and 6.4 on how to fit the chemical tube to injectors and foot valves.
6.1.5 Plug the power cord from the Hybrid system into a 10amp power outlet. Ensure
the POWER supply is off until ready to commission the unit.
6.1.6 Plug the Oxiswim Sanitiser (OS) unit into the GPO located on the Oxiswim
controller board. Switch the OS unit to the on position (refer to instructions of the
OS). The OS will automatically come on when the pump is signalled to operate.
The OS should always be on in conjunction with the system in either Fresh Water
or Chlorine mode
NOTE
Note on Filters Warranty.
Waterco will honour the warranty of all Waterco media and cartridge filters
when used with the Hybrid System, as their construction materials are
designed to withstand the injection of hydrogen peroxide. Waterco can't
support the use of any other brand of filters for use in a Hybrid System pool

6.2 Install the Chemical Injection Points
6.2.1 Acid Injection Point
I. The acid (pH) injection point is to be installed on the pool return line, after all,
other pool equipment.
II. Dry fit the chemical injection point saddles to ensure sufficient space and
clearances.
III. Ensure that the heads of the chemical injection points have a minimum of
200mm (8in) clearance so that the chemical feeder hoses may attach freely.
The chemical injection points may be installed on either vertical or horizontal
pipe.
IV. Whilst in dry fit, mark the holes to be drilled into the pipes, so they are
directly under the open head of the chemical injection point.
V. Use a 22mm (55/64 in) hole saw, drill the first hole and clean the swarf
(Figures 6.1 and 6.2)
VI. Install the lower and upper clamps (Figures 6.3 and 6.4) so that the hole is
directly beneath the open head of the upper clamp. Then secure the clamps
together using the nuts and bolts provided, tightening with an adjustable
wrench or 10mm (25/64 in) socket wrench (Figure 6.5)

VII. Using the Teflon tape provided, install the reducing bush to the top of the
chemical injection clamp (Figures 6.6 and 6.7). Hands tighten and then / turn
with an adjustable wrench (Figure 6.8). Do not over tighten
VIII. Using the Teflon tape provided, install the chemical injectors to the reducing
bush. Hand tightens, and then % turn with an adjustable wrench (Figures 6.9
and 6-10).
