SETTING AND OPERATING THE ECO-SPA:
1. TosetyourEcoSpa™rstensurethepH(7.2-7.4)andTotalAlkalinity(80ppm)
are balanced then add bromine whilst the spa is running to reach a level of
4ppm Bromine. Verify this with a reliable test kit or seek the advice of your pool
& spa professional. Please note the above bromine levels are recommended by
Australian Standard AS 3633 for water above 26°C.
2. Once the desired level of bromine is reached turn the ORP Control knob slowly
clockwise or anti-clockwise as required until the ORP Redox LED indicator
indicates “Within Range” (green) and the Cell Power LED turns off. As an
alternative to the above procedure you can set the ORP control to vertical (this
is approximately 650mV) and run the spa until the ORP within range LED is on
and Cell Power is off. Check sanitiser levels and adjust ORP control to suit.
3. If a higher or lower bromine residual is required you can adjust the ORP Control
up or down (this should be done in small increments)

the EcoSpa™ to maintain the required sanitiser level. Your EcoSpa™ has
a default setting via the controller of 2hrs and 40min run time per day. If the
numberofpeopleortimeintheSpaincreasesthentheltrationtimerequired
may be greater.
5. If the ORP (Redox) Within Range Green Led is not achieved during your daily
ltrationcycleyouneedtoeitherincreasetheltrationtimeorfollowthetrouble

lit.Thisisnormal,inthisstatetheORPRedoxLEDmayindicate“under”or
“within range” or “over”. There is some overlap of the ORP (Redox) LED’s – it
is possible for the “Within Range” and “Over” or “Under” LED’s to be on at the
same time. (Only applicable to spa operations via controllers)
7. The green “Cell Power” LED will only operate when the system is actually
producing santiser.
8. If the Red “Add Salt” LED is on you need to check your spa salt level and add
toachieveSaltleveltoatleast2,500ppm.Foreach1kgofnormalpoolsalt
added you must add about 20 grams of EcoSpa™ Activator. The EcoSpa™
ORP system is reliant on the use of EcoSpa™ Bromine Activator Salt.
TheADDSALTIndicatorisalsoaffectedbywatertemperature,asis
the unit output. It is designed for operation around 35ºC (95ºF). If the spa
temperature is less then 35ºC you may require more Salt and EcoSpa™
Bromine Activator to turn off the ADD SALT indicator.
9. What is “ORP”? EcoSpa™ uses an ORP Sensor probe to determine whether
or not bromine needs to be produced by your EcoSpa™ to sanitise the spa.
ORP levels are measured in millivolts (mV). The ORP sensor probe does
notmeasuretheactualbrominelevelofyourpool–rather,itmeasuresthe
effectiveness of bromine to oxidise and kill biological contaminants.
It is possible for two spas with identical bromine residuals to have very different
ORP levels. This is due to the effectiveness of bromine in a spa being reliant on
 otherfactorssuchaspH,stabiliserlevels,TotalDissolvedSolids(TDS), 
combined bromine levels and temperature.
In general ORP will be affected in the following ways:
Chemical Level ORP Levels
Bromine UP UP
PHUP DOWN
PHDOWN UP
Combined Chlorine & Bromine UP DOWN
Total Dissolved Solids* UP DOWN
Temperature UP UP
10. Please note your EcoSpa™ Cell is a reverse polarity type designed to clean
itself periodically. To clean itself the EcoSpa™ will shut down for a few
minutes and then reverse the polarity of its cell plates. In extreme hard water
you may need to remove and clean the cell using 10 parts water to one part

2.Werecommendthatyoucompletelydump,rellandre-balanceyourspawater
on a regular basis. The frequency of this operation will depend on spa usage.
Due to the use of recycling salts in the EcoSpa™ bromination process there
willnotbeabuild-upofchemicalcarriersorllers.However,someorganicand
inorganiccontaminantsfrombatherswillbuildupovertime,requiringdumping
of the spa water. Don’t forget to add the EcoSpa™ Activator Salt (50 grams
per 1000 litres) and pool salt (2.5kg per 1000 litres).
3. The EcoSpa™ ORP probe does not need to be cleaned when exposed to
normal spa use. It is recommended that the ORP probe be calibrated regularly
and inspected as per normal spa service cycle.
