A. Air entering your filter is dangerous and can cause the lid to separate from the tank body. 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
skimmer 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. If the D.E. is returning back to the pool upon backwashing, check to make sure the bag is seated properly on the
separation bag ring. Also check the bag to see if it is torn or missing. If the bag is torn, a replacement is needed.
C. The pressure gauge is an important part of the separation tank. 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 immediately if it fails to meet any of the requirements above.
