Hazardous pressure. Can cause severe injury or major property damage from tank blow up.

Release all pressure and read instructions before working on filter.

GENERAL INFORMATION

•Clean a new pool as well as possible before filling pool and operating filter. Excess dirt and large particles of foreign matter in the system can cause seri- ous damage to the filter and pump.

•With a diatomaceous earth (DE) filter system in place and operating cor- rectly, clean water is returned to the pool faster than pool water is being contaminated. A typical pool installation will require approximately one week to obtain and maintain the sparkle that your filter is capable of giving you.

•DO NOT use more than the recommended amount of DE in your filter. To do so can cause a buildup of DE and "bridging" between the elements which will plug the filter.

If filter is improperly disassembled or assembled, it can explode under pressure! To avoid danger of severe injury or major property damage,

always follow service instructions in this manual when working on filter!

NEVER operate this filter system at more than 50 pounds per square inch (50 PSI/345kPa) pressure! Be sure filter pressure gauge operates

when system is operating. If pressure gauge is damaged or does not work, re- place it.

Purge all air from system before operating system. NEVER operate filter with air trapped inside.

•On a new pool installation, we recommend:

1. Disassemble the filter after the initial cleanup.

To prevent severe injury or major property damage, exactly follow "Filter Disassembly/Assembly Procedure" on Page 8.

2. Remove and hose down the element assembly to remove contaminants.

•It is a good idea to remove the element assembly once a year and soak it in a filter cleaning solution to remove accumulated body oils, etc.; see Page 11, "Chemical Cleaning Procedure".

•Cleaning interval is based on pressure differential, not on length of time fil- ter is operated. Different water conditions will have different normal clean- ing intervals. If backwashing filter is not possible, use "Manual Filter Cleaning Procedure", Page 10, at regular intervals to clean filter.

•Check local codes for restrictions on backwash to waste piping, separation tank requirements and spent D.E. disposal requirements.
