Module Cleaning Procedure; Cleaning The Filter - STA-RITE PRDE40 Notice D'utilisation

7. When steady stream of water comes from air release
valve, close the valve.
NOTICE: Leaking around the Posi-Ring
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. Rotate the Posi-Ring
hind the safety latch (see Figure 2).
d. If the ring was already locked, remove it and the
filter lid. Inspect and clean the O-Ring and all seal-
ing 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-Ring
on filter tank as this may collect grit and make removal
difficult.
8. 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.
9. Empty slurry slowly into skimmer to precoat filter
module 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 "Filter
Module Cleaning Procedure", Page 8).

CLEANING THE FILTER

When to Clean:
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, clean filter (See Page 8).
2. 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.

Hazardous pressure.
Can cause severe
injury or major

from tank blow up.
Release all pressure and
read instructions before
working on filter.
