TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Air Entering Filter
System
Low water level in pool or spa.
Add water to the pool or spa.
Pump skimmer basket is clogged.
Remove all debris from the skimmer basket.
Suction cleaner hose is pulling in air.
Check the cleaner hose for damage. Replace hose as needed.
Pump lid is not sealing.
Inspect the pump lid O-ring for damage. Replace the O-ring as
needed.
Pump suction line is pulling in air.
Inspect the suction line for damage. Repair as needed.
Short Filter Cycles
Poor backwash procedure.
Backwash the filter as instructed in
Backwashing the Filter
, page 9.
Too little or too much D.E.
Backwash and add correct amount of D.E. given in Table 2, page 6.
Algae in water.
Correct and maintain proper water chemistry. Frequent backwashing
may be necessary until pool is free of algae.
Plaster dust from pool is building up in
filter.
New pools can frequently release high amounts of plaster dust into
the filter. This usually lessens over time and no action is needed.
Oils, minerals or debris building up on
filter cartridges.
Clean the filter cartridges according to instructions given on pages
9-11.
Cloud of Dirt Entering
Pool
A brief “cloud” of dirt may appear
during system start-up.
This is a normal characteristic of D.E. filters, and does not require
action.
Diatomaceous Earth
(D.E.) Continuosly
Entering Pool
NOTE: Ensure the foreign
material in the pool is
diatomaceous earth.
Internal parts not assembled correctly.
Check assembly of internal parts making sure they are correctly
installed.
Damaged manifold.
Replace manifold.
Damaged filter cartridge.
Replace cartridge.
Diatomaceous earth back up at main
drain.
Check for air leaks and repair as needed. Air leaks can cause system
to drain down allowing D.E. back to the pool.
Missing air bleed screen cap.
Replace cap.
Leak in Filter Tank
Damaged O-ring.
Replace O-ring.
Dirty O-ring.
Clean O-ring and all tank surfaces it comes in contact with.
Clamp ring is loose.
Tighten clamp ring according to
Installing the Filter Lid and Clamp
Ring
on page 7.
Crack in lid or tank body.
Replace cracked component.
High Pressure Reading
after Backwash or
Manual Cleaning
Restriction on discharge side.
Locate and correct restriction of filter.
Mineral deposits on filter cartridges.
Acid soak the filter cartridges. Refer to
Acid Soaking the Filter
Cartidges
on page 11.
Excessive water flow through filter
(pump horsepower may exceed filter
flow rate).
Determine pump flow rate and compare with maximum filter flow rate
requirement.
If heater is included in system, flow
valve on heater may be stuck open.
Adjust or replace flow valve as needed.
Pressure gauge not working properly.
Inspect and repair or replace gauge as needed.
Air entering the system can cause the lid to separate from the filter. If the below symptoms are observed, do not attempt
to remove or tighten the clamping system or perform any other servicing until you have shut off pump and relieved all
air and pressure in accordance with the
Opening the Filter
instructions (page 5). (See Important Warnings and Safety
Instructions, page i-ii)
