FILTER

Ozone will keep the water much cleaner

than any other type of water purification system. This is due to the fact that ozone neutralizes

body oils and soaps. After ozone kills the bacteria, the by-products of the process are oxygen,

carbon dioxide and filterable solids. Since filterable solids are usually at higher levels than with

conventional disinfection processes, the filter will have more work to do. Keeping the filter clean

will make a noticeable difference in the clarity of the water. It is recommended that a regular

filter cleaning schedule is established, or poor water flow through the filter will result. This will

have a direct effect on the amount of ozone that enters the water.

A word of caution: There is extremely high voltage inside the ozone generator. If you suspect

a problem, disconnect the power to the unit at the service disconnect box or main electrical

panel and immediately contact your swimming pool maintenance technician. Inspect the

ozone delivery line check valves daily for water seepage and strongly recommend replacing

the injector check valve yearly.

Check valves

Two check valves are available for the ozone delivery system, One where the ozone tubing

attaches to the ozone generator and one where it attaches to the injector. The purpose of

these check valves is to prevent water from backing up into the ozone generator. The Teflon®

ozone delivery line(s) should be inspected daily to insure water is not flowing back into the

ozone generator. Check valves should be replaced yearly. Note: The only time it is possible for

water to flow back toward the ozone generator is during a system shutdown. Always inspect

for water seepage during this time.

Fuses:

Fuse is located on the panel at the bottom of the unit.

The fuse is 3 AMP for SP-3 to SP-8 and 6

AMP for SP-16.
