Maintenance

Replace the check valve in the Ozone
Every 12 months or as required
The Teflon check valve prevents water from returning to the system. Flooded
systems (below water level) require a water trap (drain valve) to protect the
system in the event that the check valve fails. To replace the check valve
simply pull the delivery line off the check valve at both ends and replace with
new check valve.
Ozone Filter Replacement
Regularly (every 3-6 months)
Replace the Ozone air filter located under the control unit. To remove
the filter turn it anticlockwise, remove the old cotton wool and replace
with half a standard cotton wool ball. Only hand tighten the filter when
refitting.
Electrode (Cell) Cleaning
Although you have a reverse cycle (automatic cell cleaning) system, it is
recommended from time to time that the cell be checked for any accumulation
of calcium or other deposits that may have built up. We recommend cleaning
the cell once or twice a year subject to your pool's application and location.
