ozone free!
8.2.1. Weekly Maintenance
Normal pool maintenance is required
1. Backwash and rinse filter
2. Brush pool walls
3. Net out all floating debris
4. Vacuum up all debris on the pool floor
5. Adjust the pH to between 6.8-7.2 using hydrochloric acid
6. Check copper residual using supplied copper test kit. The test kit will only give true results if the
pH is between 6.8-7.2. Adjust copper on e-Clear control box via on/off switch or ionization
percentage dial. If test kit shows copper residual to be at the required 0.5ppm then switch off or
turn down the copper ionization on the e-Clear control box. If copper residual is below 0.5ppm
then switch on/ turn up the copper ionization on the e-Clear control box. The copper MUST be
checked and adjusted weekly.
7. Visually check your unit’s milliamp reading. Blue number should be between 1.60 and 2.25. Red
reading- .200 - .350
8. Visually check oxygen and copper plates for dirt, build-up and check copper plates thickness. Once
they reach under 4mm thick they should be replaced.
8.2.2. Annual Maintenance
1. Check calcium level of pool water at pool shop or using e-Clear purchased calcium test kit. Calcium
Level should be between 200-300ppm. Calcium is added at e-Clear installation to produce
conductivity in the water in order for the plates to pass current between them. Calcium does not
get used up or evaporate but only leaves the pool during back washing. Thus only needs to be
checked every year.
2. Clean the electrodes, if necessary, by removing each electrode chamber and immersing in
hydrochloric acid / water solution of 1-part acid to 10 parts water, until the buildup has dissolved.
Not more than 20 min.
3. Change pool filter glass media every 18 months. We recommend Consol glass media of grit size
0.6mm-2mm. This is finer than normal pool glass media.
