children) with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or
instruction concerning the use of the appliance by a person responsible for their
safety. Children should be supervised to ensure they do not play with the
appliance.
WARNING –Children less than eight (8) years shall be kept away unless
continuously supervised. This appliance can be used by children aged from eight
(8) years and above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning the use of the appliance in a safe way and
understand the hazards involved. Children should not play with the appliance.
Cleaning and user maintenance should not be made by children without
supervision.
WARNING –When mixing acid with water, ALWAYS ADD ACID TO WATER,
NEVER ADD WATER TO ACID.
WARNING –Do not open Electronic Control Unit. There are no serviceable
elements in the control box. Always return to Enviroswim for repair.
WARNING –Do not operate electrolytic cell without proper flow or water
circulation. A build-up of gases will result in hazardous conditions.
CAUTION –Use of chemicals other than those recommended may be
hazardous. Follow the Chemical Manufacturer’s Instructions. Do not add
undiluted chemicals directly to the pool as staining may occur. Undiluted Calcium
Hypochlorite reacts with copper and silver and can cause staining, an alternative
such as liquid chlorine (Sodium Hypochlorite) or a non-chlorine oxidiser is
recommended if shock treatment is required. Do not use Cyanuric Acid
(Stabiliser) as this will inhibit oxidation processes.
CAUTION –This unit is for use with permanently –installed pools. Do not use
with storable pools. A permanently –installed pool is constructed in or on the
ground or in a building such that it cannot be readily disassembled for storage. A
storable pool is constructed so that it is capable of being readily disassembled for
storage and reassembled to its original integrity.

If you employ a pool maintenance contractor,
ensure that they read and 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 (Cyanuric Acid)
Do not use bromine compounds
Do not use aluminium based or any other
flocculants
Do not use Soda Ash (Sodium Carbonate)
Do not use Granular Chlorine. The use of
Granular Chlorine (Calcium Hypochlorite) may
cause black staining of the pool rendering if it is
added undiluted to a pool treated by an Enviroswim
System. Use only unstablised liquid chlorine
(Sodium Hypochlorite) or OxyShock (non chlorine
Oxidiser).
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 manufacturer’s instructions supplied with each
test kit.

1 Operating Instructions
Thank you for purchasing the Enviroswim ES-3. Following these basic instructions will
allow you to enjoy the benefits of low maintenance and exceptional water quality
achievable with this system. During periods of intense use or when there has been
significant water dilution or contamination more frequent testing and active
management may be required.
Warning:
It is important that the ES-3 system only be allowed to operate when the pool
pump is running so that water is flowing through the ionization/oxidation
chamber and the ultrasonic emitter when they are in operation. Ensure that
variable speed pumps maintain sufficient water flow.
1.1 System operation
Water that is totally acceptable for drinking purposes may have a definite mineral
imbalance for use in a swimming pool. In parts of the world where mineral excesses
or deficiencies exist in natural water, the pool will need initial balancing. A balanced
pool is necessary for proper disinfection and will assure freedom from staining and
scaling problems. Mineral imbalance and improper pH control can significantly
complicate maintenance and have a serious deteriorating effect on the pool itself.
After initial balancing of the water, mineral balance must be maintained within the
proper parameters to provide continued protection and ease of maintenance.
Frequency of testing is dependent on weather and pool load.
Avoid prolonged running of the pool with a high pH and or high copper levels. This is
easily avoided by regular testing. Enviroswim recommends that you test the pool
water every two weeks.
The only chemicals necessary to keep your pool balanced and healthy will be a buffer
such as sodium bicarbonate and hydrochloric acid. Naturally, you’ll continue to
remove leaves and dust as usual, as these eat up the sanitizer and provide nutrients
for algae and bacteria.

display
This display shows the status of the Oxidiser plates and has a range of
values.
Value
Indication
01 –15
A value in the range of 1-15 indicates the
Amperage current being applied to the Oxidiser
plates. The Enviroswim unit is limited to a
maximum of 15 Amps. When the ORP Current
Control is at maximum the display should show 15
amps. If the display at maximum is below 15 amps
this is most likely due to a low TDS level. Refer to
section 3.
OF
The current being applied to the plates is
negligible or non-existent. This will be the most
likely reading when the ORP Current Control is set
to minimum
d6
The system is in de-gas mode. When the unit
reverses polarity approximately every 24 hrs it
goes onto the de-gas mode, (no power to the cell)
for approx 1 hour. This purges the cell before
powering up in the opposite polarity
Pb This will be a flashing display that indicates that
the system is not applying current to the oxidiser
plates due to any of
Air in the system
Insufficient water flow
Calcium build up on plates.

Water Sensor wire not attached or
loose.
OL
This will be a flashing display that indicates that
current is no longer being applied to the oxidiser
plates. This is done to protect the Enviroswim unit
due to excessive current draw that may be caused
by
Excessive TDS (greater than 3000ppm)
Undiluted chemicals added to skimmer

Short circuit across the plates.
SU Indicates the unit is in its start-up self-check
mode. The start-up mode lasts for 10 seconds
during which time the Control Unit checks and
monitors the system configuration. If any faults are
found these are shown on the display with the
appropriate indicator. If no fault is found the output
currents ramp up to their preset mode as
determined by the Ioniser and Oxidiser Current
Controls.

Note: Positions 11 & 12 are mainly used to build the copper levels following initial
lling with pool water when copper levels are very low or following heavy dilution from
rainfall or oods. Use these setting with care to avoid overdosing and unnecessary
wear of electrode.
If the copper is accidentally overdosed the ioniser output can be turned off for weeks
or even months until the level drops to the recommended operating level. The system
will continue to perform 100% using just the ultrasonics & oxidiser.
The daily copper output is inuenced in two ways.
1. The daily run hours of the enviroswim system
2. The set position of the ioniser knob.
Increasing either one of the above will increase copper production likewise decreasing
either will reduce copper production.

1.1.3 Adjusting Copper/Silver Levels
The desired copper range is between 0.2 to 0.5 ppm. The Enviroswim system works
best at these levels. To increase copper levels, increase the run time and/or ionizer
output of the Enviroswim system. To reduce copper levels, turn down the ionizer
output of the Enviroswim system. As a guideline, to reduce copper levels from 0.7 to
0.4 ppm, the Enviroswim ionizer system can be left off for 7-10 days, dependent on
weather and bathing loads. Levels are easily checked by means of the supplied
copper test kits (reorder from Enviroswim).Always ensure pH is balanced before
testing copper levels in order to avoid getting a false reading.
It is very important that copper levels are not allowed to exceed 0.5 ppm for extended
periods, as copper staining may appear. Prolonged high copper and/or high pH levels
will lead to the copper coming out of suspension, and may produce a very light blue
stain on the mortar of pebble pools. This effect is not harmful to swimmers or the
pool, and if desired can be removed with some effort. Pool owners that have let this
happen find the blue tint actually enhances the pool water’s appearance.
If the copper level rises above 0.5 ppm, turn down the Enviroswim ionizer unit and
dilute the pool with fresh water to reduce the copper level to 0.4 ppm. Unlike chlorine,
copper/silver are extremely stable in water making the level very easy to maintain.
Note:
Enviroswim will not be held responsible for damage caused by excessive
copper levels.
NOTE: If you take a water sample to a pool shop for a copper test, you may get
a false reading if the pool pH has been high during the 24-hour period prior to
the sample being taken from your pool. Some types of testing equipment can
also give a false reading due to the silver content in the sample. We strongly
advise that you use the test kit and instructions provided with the Enviroswim
system to avoid misleading results that can cause high copper levels and
excessive wear of the copper/silver anodes.
When using the supplied test kit ensure that you look down the test
tube when comparing to the colour chart. The colour is best read in the
shade.

2 Basic Theory
There is no such thing as a maintenance-free pool. However, the Enviroswim system
requires only a few minutes each week to keep your pool in top condition while it
saves money. This section of the manual gives some basic insight into the theory of
the processes at work on your pool when using the Enviroswim system.
2.1 Ionization
The use of copper and silver to sanitise water is well documented and the process has
been used for thousands of years. Copper is a very powerful algaecide and silver is a
very powerful biocide. When the two metals are combined and introduced to the water
using electrolysis, they become a formidable sanitiser. The required residual level of
copper and silver introduced to the swimming pool is well below acceptable drinking
water standards making for a very safe residual sanitiser.
2.2 Electronic Oxidization (ORP generator)
Traditionally copper and silver
ionisation systems have
required an oxidiser to be
added to the pool water to help
burn out organic compounds
(oils, dust, leaf stains etc.). The
most common form of oxidiser
used for this purpose has been
chlorine. There is a growing
concern regarding the adverse
health effects of chlorine and its
associated by-products
(Chloramines)
Enviroswim has eliminated the need to add chlorine to the pool by incorporating an
electronic oxidising unit into the system. ORP stands for Oxidation-Reduction
Potential. In practical terms, it is a measurement of the ability to oxidise contaminants.
ORP is the only practical method we have to electronically monitor oxidiser
effectiveness. In some parts of the world, it is also known as Redox Potential. Using
electrolysis the Enviroswim system produces the oxidiser in sufficient quantities to
maintain an acceptable ORP.
2.3 Ultrasonics
Ultrasonics used in the Enviroswim 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.

3 Initial System Start-Up
If you employ a pool maintenance contractor, ensure that
they read and follow these instructions as an Enviroswim
System pool differs from common chlorine/salt pools.
These instructions should be followed whenever the pool
has been refilled or the Enviroswim system is restarted after
a prolonged shutdown.
For ideal operation Enviroswim requires a TDS level of between 1000 and 1500 ppm
to provide conductivity for its electronic processes. When converting Salt Water Pools
or pools where TDS exceeds 2000ppm please contact Enviroswim.
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.
Ensure that the pool water is balanced (Alkalinity, pH and calcium hardness).
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 litre pool would take 48-60 hours of operation to build up the copper
level to the required 0.25 ppm. Larger pools may take up to 2 weeks.
Perform the following steps to allow the Enviroswim system to be running in the start-
up mode:
1. Balance the water as per above. Ensure all Enviroswim switches are set to
OFF and variable controls (Ioniser and ORP) at minimum (fully counter-
clockwise).
2. Turn on the pool pump so that water is
flowing through the filtration system and
the Enviroswim ionization/oxidation
chamber and ultrasonic emitter pipe. Set
the left hand switch on the Enviroswim
unit to MANUAL. Make sure that the
ionization/oxidation chamber is filled with
water.
3. Turn on the right hand ON/OFF switch on
the control box.
4. Turn the knob on the control box under
the ORP meter slowly clockwise until the
ORP meter reads between 13 - 15 Amps.
5. Turn the ioniser switch to maximum. Run
the unit for approximately 1 hour per 1000
litres of water and test copper level.
24-48

© Enviroswim 2014 Page 16 of 23 AUS Rev 3.1
6. Perform chemical tests to determine readings for pH, ORP, alkalinity,
copper, and calcium hardness then adjust accordingly. Refer to Operating
Manual for appropriate treatments.
7. Test the copper level and when in the range 0.2-0.4 ppm set the system for
the appropriate run time and adjust the Ioniser output to around 50%.
8. Startup is now complete. Refer to the operating manual for a guide on run
times. Remember every pool is different. Factors that will impact runtime are
location, bather load, season, type of cover and water temperature.
When can I use the pool?
It is OK to use the pool while the Copper levels are being established
provided the Enviroswim system is processing the water continuously and
the correct water balance (pH, alkalinity and hardness) is established. The
Oxidation process will treat organic matter and as water flows through the
cell it will be being treated with concentrated Copper and Silver ions. We
recommend that the water is allowed to circulate at least once (allow 1 hour
per 10,000 litres) before swimming.
High Cyanuric Acid levels
Where a pool has been treated previously with chlorine (particularly with
tablet feeders) there may be high residual cyanuric acid levels. This can
adversely affect operation of the ES-3. Contact Enviroswim.

4 Maintenance
4.1 Basic Maintenance
The Envirowim system is very low maintenance. Only the copper and silver electrodes
are consumable and require periodic adjustment and replacement. The oxidizer plates
and copper/silver electrodes are self-cleaning and the ultrasonic system is
maintenance free.
4.1.1 Fuse
Fuse replacement: 240 Volt, 10 Amp, Slow Blow
WARNING: There is a risk of electrical shock, fire and damage to the unit if an
incorrectly sized fuse is installed in the fuse holder.
4.1.2 Replacement of
Electrodes
The copper/silver electrodes are a consumable and
will require periodic replacement. The life of the
electrodes will depend on many factors including
pool use, maintenance, dirt and other debris that are
allowed to build up in the pool. The electrodes
should be changed before they become so small that
they fall off the stainless steel threaded rod that
holds them in place.
Note: Replacement electrodes can only be purchased through Enviroswim.
Using any electrodes not supplied by Enviroswim will void any remaining
warranty. Enviroswim will not be held liable for the performance or
effectiveness of the system when other manufacturers’ electrodes have been
installed.
4.1.3 Cleaning Oxidiser Plates
Plates should only be cleaned if severely scaled and the ES3 is unable to draw 15
amps (as per the digital display). Scaling on the plates generally indicates that the pH
has been high for extended periods (above 7.6). Refer to section 5.1 on Langlier
Saturation Index and make sure that the pool is operated with
an appropriate LSI.
Before cleaning check the following
TDS is within range –1000-1500 ppm
No loose connections.
Scale may be loosened by striking gently with wooden or

© Enviroswim 2014 AUS Rev 3.1Page 20 of 28
© Enviroswim 2014 Page 18 of 23 AUS Rev 3.1
plastic objects. Take care not to damage the plastic separators.
Once all excess scale is removed clean plates by soaking in a 75/25% ratio
water/hydrochloric acid solution. A 1.25 litre softdrink bottle with the top cut off is an
ideal size for bathing the plates. Do not leave the plates in the solution for extended
periods - 3 minutes should be sufficient if excess scale has been removed. Ensure
that the water level sensor is cleaned.
Never use metal objects to clean the plates as this will damage the coating.
Remember : Always add Acid to Water when diluting.
