GAUGE/INSPECTION PORT ADAPTER
The gauge/inspection port adapter provides an easy way to
look into the filter at the “top” area of the tube nest assembly.
It gives a quick inspection capability to check tube nest
condition (algae, calcium or D.E. build-up, etc.) without
requiring removal of the filter head. It also allows you to wash
off trapped debris and excess D.E. from between the
Flex-Tubes and from under the tube sheet by spraying with a
garden hose, or use Hayward’s Jet-Action Cleaning Wand
(EC2024) which attaches to a garden hose.
To remove adapter—
shut off pump and valves and drain
water in filter to below port. Unscrew adapter, with gauge,
counterclockwise.
To reinstall—
thread adapter, with O-ring in place, securely
into filter housing.
PREVENTIVE MAINTENANCE
While Perflex filters are basically resistant to the difficulties
often encountered as a result of chemical build-up in swimming
pools, it is important to keep in mind that the mineral content
in a pool increases every day as a result of the chemicals
added and the normal water evaporation process. If the
concentration of minerals is allowed to get too high, the
minerals will form deposits on the Flex-Tubes inside the filter,
and will eventually result in shortened filter cycles. To guard
against this, a yearly chemical cleaning (soaking) of the
Flex-Tube assembly is suggested. Use commercially available
20% muriatic acid added to water in 1 to 1 ratio; or use other
commercial filter element cleaner mixed according to the
package instructions. Use a plastic container and take extreme
caution when handling cleaning agents as they can be harmful
to the eyes, skin and clothing. After cleaning, thoroughly flush
all affected parts with cold water.
