The Nature 2 cartridge for the Pro A Plus lasts six (6) months. Use the
month indicator ring to identify the month when the cartridge must
be replaced.
To replace the cartridge:
1. Shut off the pool pump and filter.
2. Close valves between filter and pool to prevent pool draining.
3. Turn locking ring counterclockwise to remove and lift off cap.
4. Remove the old cartridge and discard in household trash. Insert
the new cartridge.
5. Position cap flat on the vessel housing. Important: Make sure
the o-ring is secure in the groove on the vessel top, not on
the underside of the cap. Turn locking ring clockwise until it
locks into place. Do not over tighten.
6. Rotate the month indicator ring on the cap to indicate the current
"Install" month and the next "Replace" month.

Adding Chlorine Tablets
Please review the chemical use hazard instructions on the first
page of this manual before opening the chlorine chamber.
Under normal conditions, the large-capacity chlorine dispenser of
the Pro A Plus provides a minimum of one (1) month chlorination for
large pools. The chlorine feed rate is regulated by adjusting the chlorine
regulator dial to control the rate of water flow through the chlorine
chamber, and the amount of Tri-Chlor tablets placed in the feeder.
To add: Turn locking ring counterclockwise to remove and lift off cap.
Add the desired amount of slow dissolving Tri-Chlor tablets, up to 4.5
lbs. Replace cap and turn locking ring clockwise until it locks.
Winterizing
Consult your dealer for complete information on pool care and
maintenance in cooler temperatures.
In cold climates, where the pool is closed:
1. Remove the Nature 2 cartridge and discard with household trash.
2. Review chemical use hazard on page one of this manual
before opening the chlorine chamber. Carefully remove any
remaining chlorine tablets.
3. Remove and save the two (2) drain plugs.
4. Rinse out Pro A Plus thoroughly with water.
5. If blowing lines clear with air, set chlorine regulator dial to +.
6. After completing winterization, loosen locking rings.
For Spring start up:
1. Replace the two (2) drain plugs.
2. Start up your pool as normal.
3. After the water has been balanced, insert the new Nature
cartridge, add the chlorine tablets, and complete the cartridge
