TROUBLESHOOTING

A. Air entering your filter is dangerous and can cause the lid to blow off. Correct any conditions in your filtration
system that allow air to enter the system.
1. Some common ways to identify air entering the system:
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; low water level, clogged skim-
mer basket, split suction cleaner hose, leak in pump hair and lint pot lid, or leak in pump suction line.
c. Air bubbles coming out of water return lines into pool or spa with pump running, see items 1.a and 1.b
of this section.
d. Air is discharged from the air relief valve on top of the filter when the valve is opened with the pump
running, see items 1.a and 1.b of this section, above.
B. Until the water initially put into the pool has been completely filtered, short filter cycles in between cleanings
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 cycles, requiring frequent cleaning.
C. If pressure drops on gauge, check skimmer basket and pump basket first for debris. If the baskets are clean,
shut off power to pump and turn off any automatic controls. Then 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.
D. The pressure gauge is an important part of the filter. It is your primary indicator of how the system is operating.
Maintain your pressure gauge in good working order. Check the operation of your pressure gauge in the
following manner:
1. The pressure gauge should go to zero (0) when the system is turned off and pressure is relieved.
2. The pressure gauge should indicate pressure when the system is operating.
3. The pressure gauge should be readable and not damaged in any way.
4. Replace the pressure gauge if it is not meeting the requirements of items D.1 through D.2 of this section,
above.
