7) Whenever adjusting spa chemicals, less is better. Add chemicals in small amounts over several days.
Does your spa have a Fresh Water Ozone system on it?
1) The Fresh Water Ozone System is very simple to monitor. Follow the procedures listed below to ensure
continued clean, healthy water.
2) Using chlorine and a DPD test kit, measure Free Available Chlorine (FAC) and Total Chlorine (TC). As long as
the difference is less than 0.5 ppm, the powerful oxidizer from the Fresh Water Ozone system is entering your
spa and cleaning your water. You will only need to add small amounts of chlorine to maintain a sanitizer.
3) Check your pH, total alkalinity and calcium hardness as recommended by your Sunrise Spa dealer, and adjust
if required. Please note: With the Sunrise Fresh Water Ozone system, maintain a pH between 7.6 and 7.8.
4) Check the bubble mist entering the spa, via the dedicated ozone/return jet, for consistency. An irregular
bubble mist could indicate a blockage in the pump or pipes, a dirty cartridge(s) , low water level or pump
operation problems.
5) On an ultraviolet ozonator, check the glow fitting on the ozonator for a blue colour to ensure that the bulb is on.
On a CD ozonator check that the ‘power on’ indicator light is on.
6) Disconnect the tubing from the glow fitting and place your finger over the end of the tubing to feel for suction.
This will ensure that the bubble mist entering your spa is coming through the Sunrise Fresh Water Ozone
system.
REMEMBER: Your spa water cannot be treated if the circulation system is not operating. The longer the spa's
circulation system runs, the cleaner your water will be. This is not a problem on spa with a dedicated circulation pump.
However, on models that use the low speed of a 2-speed pump to circulate the water, the filter cycle should be no less
than 4 to 6 hours per day.
