Chlorine Free Water Purification

Free Heat

For the Ultimate
Chlorine free & Oxygen Sterilized

Fresh Water Pools, Swim
spas and decorative pond sanitising.

Thousands of people worldwide have chosen to convert their pools from chlorine and salt to EnviroSwim Fresh Water Technology.

Some examples on the Gold Coast, Queensland Australia are the State of the art ECO Village at Currumbin Valley, the Radisson Resort, Circle on Cavill Resort, plus the International ocean liner known as THE WORLD.*

WHY is this system now the preferred option today?
Chemically Free Oxidisers are produced direct from the water itself and delivered into the water stream in grams per minute via "Electronic Oxidation" complete with copper and silver Ionisation.

Ultrasonics used in the Enviro Swim system further helps to improve the water quality by removing existing scale and preventing the formation of scale caused by silica in the water. This process improves the efficiency and reduces the operating costs of the pool filtration / circulation and heating equipment.

The EnviroSwim provides the latest and efficient TOXIC FREE purification technology available today for not only Swimming Pool water and Swim Spas, but also for decorative water features ponds and waterfalls.
Commercial applications that require healthy water such as chicken growers and hatcheries should consider this method as a healthier alternative to chlorine treatment of the water used in their process.

Follow these instructions as an EnviroSwim System pool differs from common chlorine/salt pools.

The best results with the EnviroSwim system are obtained by following a few simple rules:

· Do not use stabilizer
· Do not use bromine compounds
· Do not use aluminium based or any other flocculants
· Do not use Soda Ash
· Do not use Granular Chlorine. The use of Granular Chlorine may cause black staining of the pool rendering if it is added undiluted to a pool treated by an EnviroSwim System.
· Do not throw un-dissolved chemicals into the pool.
· Clean the pool filter regularly.

Due to the many different test kits on the market, we recommend that you follow the manufacturers instructions supplied with each EnviroSwim test kit.

Preparation to Install

New pool:
Refer to the manufacturers detailed installation manual supplied with the unit.

Retrofit an exisiting pool:
If you retrofit a chlorine pool, the chlorine will have evaporated in a couple of days so you don't need to refill your pool.
If retrofitting a saltwater chlorinated pool, there is no need to change over the water either. Usually there is some level of solids leftover from the salt chlorination process, but the system is designed to cope with that.

Increase hardness:
Add calcium to your pool until the hardness has reached 250 ppm. The best is to use calcium chloride flakes or pellets.
Your local chemical wholesaler will stock this. The initial dose will be about 25 kg on a 100,000 ltr pool.

Enviro Swim Freshwater Pool
Management System


A detailed installation, water balance and operating manual is provided with each EnviroSwim unit.

Please contact Free Heat with any questions relating to your EnviroSwim Freshwater Swimming Pool system.

Pool shops supplying non-EnviroSwim systems do not, have the experience to advise you correctly.

For ideal operation EnviroSwim requires a TDS level of between 800-1200 ppm to provide conductivity for its electronic processes. When converting Salt Water Pools or pools where TDS exceeds 2000ppm please contact Free Heat.

If TDS is low, adding 5kg of pool salt per 10,000 litres of water will raise the TDS by around 500ppm.

For new pools, or those that have just been refilled, add pool salt to ensure the conductivity of the water is high enough for the ionization process to take over. If retrofitting to an existing pool the conductivity of the water should be sufficient for the EnviroSwim system process to initiate.

When the system is initially installed, it will need to be run continuously for a time to allow the various processes to take effect in the pool.

The time taken to initialize the system will vary, depending upon the volume and conductivity of the pool water.

Typically a 50,000 liter pool would take 48- 60 hours to build up the copper level to the required 0.25 ppm.

Perform the following steps to allow the EnviroSwim system to be running in the start-up mode:

1. Turn on the pool pump so that water is flowing through the filtration system and the EnviroSwim ionization/oxidation chamber and ultrasonic emitter pipe.

2. Make sure that the ionization/oxidation chamber is filled with water.

3. Turn both controls (Ioniser and ORP) on the EnviroSwim control box fully counter-clockwise.

4. Turn on the green power switch on the control box and make sure that the light in the switch is illuminated.

5. The LEDs on the control box should be illuminated as follows from left to right; the first LED will alternate from red to green approximately every six minutes, second LED will change colour every 3-5 seconds. Turn the knob on the control box under the ioniser meter slowly clockwise to its maximum position. This setting provides maximum copper/silver ion production providing that the conductivity of the water is high enough.

6. Turn the knob on the control box under the ORP meter slowly clockwise until the ORP meter reads between 13 - 15 Amps. If the maximum output is below 12 amps the conductivity of the water may be too low.

7. Allow the unit to run for 48 hours.

8. Perform chemical tests to determine readings for pH, ORP, alkalinity, copper, and calcium hardness.

9. Once readings are at the following levels:
· Alkalinity: 80 to 150 ppm
· pH: 6.8 to 7.2 ppm (fiberglass pool)
· pH: 7.2 to 7.5 ppm (cement pool)
· Copper Content: 0.2 to 0.4 ppm
· Calcium Hardness: 200 to 250 ppm
· ORP: 500-750 millivolts minimum; equivalent to a reading of 0.5-1.5 ppm of chlorine using a DPD test tab

Reduce the run time on the unit to 1 hour per day for every 10,000 litres of water in the pool and turn the knob on the control box under the ioniser meter slowly counter-clockwise until the ioniser output is mid setting (50% output) The system is now operating normally and the initial start-up phase is completed.
The copper output could later be adjusted as necessary to find a setting that will maintain the 0.2 – 0.4 ppm recommended level.

Phosphates- test for monthly - please contact your dealer if phosphate is present. Backwash the filter monthly or sooner –or if the pressure gauge on filter indicates the need. See Backwash instructions.

Ultrasonic algae control

Ultrasonic algae control - Algae gone forever!

What are Algae and how can we control them
Algae are a natural component of most aquatic ecosystems and are found in both fresh and marine waters. They range in size from large kelps (metres in length) to those visible only under a microscope. Algae blooms occur when there are high nutrient levels, low flows, low wind and high temperatures.

There is now a new way to control algae
Ultrasonic waves destroy the algae from within. These ultrasounds are inaudible to humans and pose no threat to people, animals or fish. The effectiveness of this technology is amazing and it will destroy nearly all forms of algae, with minimal impact on the aquatic environment.

The product range is optimised depending on size and useage, see the different models available below for ornamental ponds, swimming pools, water storage tanks, lakes, cooling tower, irrigation and wastewater installations.

Choose one of the models below:
