SECTION III. TROUBLE SHOOTING.
A. AIR ENTERING YOUR FILTER IS DANGEROUS.
1.
Air entering your filter can cause the lid to blow off. Correct any conditions in your filtration system that allow air to enter the
system. Some common ways to identify air entering the system are listed below.
a.
Low water level in pool or spa - skimmer is starving for water with pump running. Add water to pool or spa.
b. Air bubbles or low water level in pump hair and lint pot are caused by the following factors:
(1)
Low water level.
(2)
Clogged skimmer basket.
(3)
Split suction cleaner hose.
(4)
Leak in pump hair and lint pot lid.
(5)
Leak in pump suction line.
c.
Air bubbles coming out of water return lines into pool or spa with pump running, see steps A.1.a-b, above.
d. Air is discharged from the High Flow™ manual air relief valve on top of the filter when the valve is opened with the pump
running, see steps A.1a-b above.
B. LIMING-UP.
1.
A stiffening of the fabric caused by mineral deposits. It usually is due to deposits of either magnesium or calcium or both.
a.
Removal of these may be accomplished by soaking the grids in six (6) parts water to one (1) part hydrochloric acid
(muriatic acid). Refer to Section II.H.2, Cleaning Filter Elements with muriatic acid for cleaning instructions.
C. CLOUD OF DIRT.
1.
A brief "cloud" of dirt may appear immediately when the filter starts. This is a characteristic of diatomite filters.
D. SHORT FILTER RUNS.
1.
Until the water initially put into the pool has been completely filtered, short filter runs are normal. In most cases, pool owners
are dismayed by the undesirable color and appearance of water in a newly filled pool. Plaster dust can be responsible for short
filter runs, requiring frequent cleaning.
E. PRESSURE DROPS ON GAUGE.
1.
If pressure drops on gauge, shut off power to pump and turn motor shaft with your fingers. If it turns freely then the pump
must be disassembled and the impeller checked to see if it is clogged. If it is not frozen or clogged then there is an obstruction
in the line between the pool and the pump.
F. PRESSURE REMAINS HIGH AFTER BACKWASH.
1.
If pressure remains high after backwash - backwash filter again. If still high, treat for conditions covered by item B above.
G. MAINTAIN YOUR PRESSURE GAUGE IN GOOD WORKING ORDER.
1.
The pressure gauge is an important part of the filter system. It is your primary indicator of how the system is operating.
Check the operation of your pressure gauge in the following manner.
a.
The pressure gauge should go to zero (0) when the system is turned off and pressure is relieved.
b. The pressure gauge should indicate pressure when the system is operating.
c.
The pressure gauge should be readable and not damaged in any way.
d. Replace the pressure gauge if it is not meeting the requirements of items a. through c. of this section.
H. DIATOMITE IS CONTINUOUSLY ENTERING THE POOL.
1.
Inspect the elements for any tears or holes. Inspect the internal air bleed sock for tears and proper installation.
