GENERAL INFORMATION

Hazardous pressure. If filter is improperly disassembled or as-
sembled, it will explode under pressure. To avoid danger of severe injury or
major property damage, always follow service instructions in this manual
(Pages 8 to 10) when working on filter.
Risk of explosion. Never operate this filter system at more than
50 pounds per square inch (50 PSI/345kPa) pressure!
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 cartridge filter system in place and operating correctly, clean water is
returned to the pool faster than the pool water is being contaminated. A typi-
cal pool installation will require approximately one week to obtain and main-
tain the sparkle that your filter is capable of giving you.
Keep pool water pH at recommended level (7.2 to 7.6).
Be sure both clamps are in place and knobs are securely tightened before
starting filter.
Maintain pressure gauge in good working order. Replace gauge if it fails or is
damaged.
Make sure internal air bleed tube and air bleed filter (Key Nos. 13 and 14,
Page 14) are in place before operating filter. Clean air bleed periodically.
Cleaning interval is based on pressure differential, not on length of time filter
is operated. Different areas and water conditions will have different normal
cleaning intervals.
NOTICE: Some pool disinfectants may clog filter media. To maximize media
life and filter cycle time, closely follow disinfectant manufacturer's instruc-
tions when cleaning pool or filter.
On a new pool installation, we recommend:
1. Turn to Page 8 for instructions and disassemble the filter after the initial
cleanup.
2. Remove and hose down the element assembly to remove contaminants.
