CHAPTER 3
: FILTER MAINTENANCE
Filtering
1. Filtration starts as soon as flow is steady through the
filter. As the filter cartridge removes dirt from the pool
water, the accumulated dirt causes a resistance to
flow. As a result, the gauge pressure will rise and the
flow will decrease.
2. Clean or replace the cartridge filter element when the
pressure rises 7-10psi above the starting pressure,
or when flow decreases below desired rate.
Remove/Reinstall Cartridge Filter Element
1.
Removing Cartridge Filter Element
: Shut the
pump off.
2. If filter is located below water level, close valves to
prevent backflow of water from the pool.
3. Open air relief valve by turning it counter-clockwise
until loose.
4. Loose drain plug so water will drain.
5. Open locking ring counter-clockwise and remove
the filter element.
6. Lift out the cartridge filter element and clean or
replace if needed.
1.
Reinstalling Cartridge Filter Element
: Clean any
collected debris from the bottom of filter body.
2. Carefully place the cartridge filter element over
the tie rod and into filter body ensuring that the
cartridge sits evenly on the collector hub in bottom
of filter body.
3. Tighten locking ring by turning it clockwise. (Hand
tighten only.)
4. Now go back to the
Starting the Filter
section and
follow the remaining steps.
Cleaning Cartridge Filter Element
1. The cartridge filter element can be cleaned by
pressure washing with a garden hose. You can also
use attachments such as a Filter Flosser Cartridge
Cleaner (item #6304) or a Magic Filter Cleaning
Wand (item #1734).
Note
: The cartridge is easier
to clean when dry.
2. Allow the cartridge filter element to fully dry and
carefully brush pleated surface areas to remove
the fine dirt and particles.
3. Algae, suntan oil and body oils can form a coating
on the cartridge filter element pleats which may
not be thoroughly removed by hosing. To remove
such materials, use
Doheny’s Cartridge Cleaner
(item #4848) solution to soak the cartridge
filter element in. Follow the
PRECAUTIONARY
STATEMENTS
and the
DIRECTIONS FOR USE
on the back label of the cleaning solution.
5.
Note
: Having a spare cartridge filter element on hand
ensures that your filter will always be ready to
operate at peak efficiency.
Winterizing the Filter
1. The filter should be drained and/or removed
from its operating location and stored in a cool, dry
place where temperatures are expected to fall
below freezing.
2. Remove and clean the cartridge filter element by
following the Remove/Install and Cleaning sections
of this manual. Reinstall cartridge filter element in
the filter tank.
3. Tighten locking ring by turning clockwise by hand.
