INITIAL START-UP
Be sure pump is OFF before starting procedure.
your DE filter without a diatomaceous earth precoat!
1. Securely lock Posi-Lok™ ring in place by rotating ring CLOCKWISE until it
"clicks" past the safety latch (see Figure 3). Stop turning as soon as the
ring clicks past the latch. The ring may feel slightly loose, but it will tighten
up when pump is on and filter is under pressure.
2. Fill trap on pump with water.
3. Open air release valve on top of filter.
4. Open isolation valves.
5. Start pump to purge air from system.
6. When steady stream of water comes from air release valve, close the
valve.
NOTICE: Leaking around the Posi-Lok™ ring may indicate that the ring is
not fully locked. In this case, proceed 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 behind 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. Use
four pounds of DE for Model PLD70; use six pounds of DE for Model
PLD50. DO NOT use more DE than recommended.
NOTICE: Using more than the recommended amount of DE will clog the
filter. Using less than the recommended amount will give an uneven
2149 1195
precoat and shorten the life of the element.
8. Empty slurry slowly into skimmer to precoat filter element with an even
filtering precoat.
After filter is operating, record filter pressure gauge reading in owner's
manual for future use.
NOTICE: When installed on a new pool, after approximately 48 hours of
operation disassemble filter and clean out plaster dust , construction debris,
etc. (see "Module Cleaning Procedure", Page 8).
FILTER DISASSEMBLY/
ASSEMBLY PROCEDURE
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.
Do not operate these filters at more than 50 PSI (345 kPa) under
any circumstances!
To prevent serious damage to the element fabric, NEVER run
Hazardous pressure. Before disassembling filter:
