valve, close the valve.

NOTICE: Leaking around the Posi-Lok™ ring may indi- cate that the ring is not fully locked. In this case, pro- ceed as follows:

a.Stop the pump, close the isolation valves, and open the air release valve to release any pressure within the filter.

b.Remove the drain plug and drain all water from the filter.

c.Push down on the top of the filter to fully seat the upper tank shell.

d.Rotate the Posi-Lok™ clockwise until it locks be- hind the safety latch (see Figure 3).

e.If the ring was already locked, remove it and the upper tank shell. Inspect and clean the O-ring and all sealing surfaces. Relubricate the O-ring.

NOTICE: Lubricate O-ring only with the silicone grease provided or equivalent, as other lubricants may cause the ring to swell. DO NOT lubricate

Posi-Lok™ ring or threads on lower tank shell as this may collect grit and make removal difficult.

7.To prepare precoat slurry, mix diatomaceous earth (DE) and water. DO NOT use more DE than recommended.

NOTICE: Using more than the recommended amount of DE will clog the filter. Using less than the recom- mended amount will give an uneven precoat and shorten the life of the element.

8.Empty slurry slowly into skimmer to precoat filter ele- ment with an even filtering precoat.

After filter is operating, record filter pressure gauge read- ing in owner's manual for future use.

NOTICE: When installed on a new pool, after approxi- mately 48 hours of operation disassemble filter and clean out plaster dust , construction debris, etc. (see “Module Cleaning Procedure", Page 8).

CLEANING THE FILTER

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

Release all pressure and read instructions before working on filter.

When to Clean:

NOTICE: If installation does not allow backwashing, use module cleaning procedure regularly (see Page 8).

1.With a new filter:

a.Record filter operating pressure at startup. When pressure reaches 10 PSI (69kPa) above startup op- eration pressure, stop pump for 30-60 seconds to allow filtering cake to release.

b.Restart pump to form new cake. Pressure should now be less than 10 PSI (69kPa) above startup op- erating pressure.

c.If pressure is still more than 10 PSI (69kPa) above startup operating pressure, backwash filter (see below).

2.Thoroughly clean air bleed assembly on top of filter module EVERY time filter is opened. Be sure to remove all debris from screen. Replace screen if damaged.

3.At least twice a year, manually clean filter module ac- cording to instructions, Page 8. At least once a year, follow instructions under “Special Cleaning Instructions”, Page 8, as well.

Filter Backwash Procedure:

To prevent equipment damage and possible injury turn pump OFF before changing valve position.

NOTICE: Before backwashing with a separation tank, review separation tank owner's manual for instructions.

1.Stop pump.

2.Change valve position.

a.If using Multi-port Valve, set it to backwash position.

b.If backwashing with a Two Position Slide Valve, push handle to full down position.

3.Start pump and run it for 3 minutes.

4.Stop pump and open tank bottom side drain. NOTICE: A 1-1/2” drain valve is recommended.

5.Start pump and run 1 minute, backwashing through fil- ter valve and tank drain.

6.STOP PUMP, return filter valve to filter position and close tank drain.

NOTICE: Do not vacuum pool while backwashing filter.

7.Compare pressure reading on gauge with reading recorded after initial startup. The two readings should be very close; if not, do "Module Cleaning Procedure", Page 8.

FILTER DISASSEMBLY/ ASSEMBLY PROCEDURE

Hazardous pressure. Before disassembling filter:

1.STOP PUMP.

2.CLOSE isolation valves.

3.OPEN air release valve and drain fitting.

4.WAIT until all pressure is released and water drained from filter tank and system before loosening Posi-Lok™ Ring.

Disassembly:

1.Stop the pump.

2.Close isolation valves to prevent flooding.

3.Open air release valve on top of filter tank to release all pressure from inside of tank.

NOTICE: Make sure that waste water disposal complies with local codes and ordinances.

4.Remove drain plug and drain all water from tank.
