4. If you operate the EcoSpa in hard water (high calcium hardness) your cell
may build up excessive calcium scale. This can be easily removed by cleaning
it. To clean the cell, turn off the brominator, disconnect the cell leads from
control box and unscrew the barrel unions from the plumbing. Add 1 part
Hydrochloric Acid to 10 parts water in a suitable container and immerse the
cell in this solution. It should not take more than a few minutes to clean. While
the calcium is dissolving off the cell you will notice bubbles. When the bubbling
stops, the cell is clean.
5. After a few years in normal domestic use, your Eco-Spa Electrolytic cell will
require replacement. Contact your local Eco-Spa dealer for assistance.
TROUBLE SHOOTING GUIDE:
1. Red “No Flow” light is on but has water flow:
• Pipe or Cell is partially blocked
• Adjust pressure switch (see arrows on side of pressure switch
– lift lock at back)
2. No display:
• Main power outlet switched off or filter pump not running
• Eco-SpaTM not plugged into main outlet or main outlet power off
• EcoSpa not plugged into ozone outlet
• Dip switches H & I not set (refer page 6, point 4)
• When pump is off (If installed with a spa controller - this is normal)
3. Unsatisfactory Bromine Residuals:
• Faulty or out of date test kit
• ORP Control set too high or too low
• ORP Probe requires cleaning or removal of debris
• Running times too low or bather load too high
• Eco-SpaTM Bromine Activator Salt not added
WARNING: If Eco-Spa TM probe is disconnected or not properly connected to
control unit then your Eco-Spa TM will continue to produce Bromine and may reach
dangerous levels. Always ensure connections are intact and if cell power light is
continually on or you smell high bromine levels in the Spa turn off the Eco-Spa TM
and check the connections.
9. Add Eco-Spa TM Bromine Activator Salt at the rate of 50 grams per 1000 litres of
water. Add normal pool salt at the rate of 2.5kg per 1000 litres of water. Your
Eco-Spa is now ready to use and enjoy. Please note the Eco-Spa TM must be
powered when filter pump is running.
10. You must change the spa water regularly and add new Eco-Spa TM Bromine
Activator Salt and Pool Salt. The frequency of water changes will be affected
by spa use, the more the spa is used the more frequently the water changes
will be required.
For installations with a Davey Spa Power Controller:
• The manifold should be located after the spa controller.
• The EcoSpa must be purchased with a special AMP cordset.
• The AMP power plug is connected to the Davey spa controller via the outlet
labelled “Ozone”.
• The EcoSpa will then operate while a pump is circulating water through the
system.
