Pump and DE Element Filter System Installation and User’s Guide
Section 1
Pump and DE Element Filter Overview
This system operates under pressure and if assembled improperly or operated
with air in the water circulation system it can separate and result in an accident
causing serious bodily injury. A warning label has been affixed to the filter and
should not be removed. Keep safety labels in good condition and replace if
missing or illegible. (For free labels call, (919)-774-4151). Pumps and filters
should never be tested or subjected to air or gas under pressure. All gases are
compressible and under pressure create a danger. Serious bodily injury or
property damage could occur if the pump or filter is subjected to air or gas
pressure.

The system consists primarily of a centrifugal pump, a DE element filter, a
connecting hose and a mounting base. Your centrifugal pump is driven by an
electric motor. The motor is directly attached to the pump impeller. As the
electric motor turns it causes the water to flow. The water flows into the hair
and lint pot inlet and through the basket assembly to pre-strain large particles.
The flow then enters the center of the pump housing. The flow goes through
the impeller into the stationary diffuser, out the pump discharge port, through
the connecting hose and into the filter inlet port at the bottom of the filter. The
water is distributed evenly across the DE filter element. The dirt is removed
by the element and the clean water flows through the outlet port at the bottom
of the tank. The clean water then returns to the pool through the piping or
hoses.
After a period of time, dirt will accumulate in the filter element causing a
resistance to the flow of water through the filter. This resistance results in a
diminished flow of water and a rise in the pressure of the filter. Eventually the
filter element will have removed so much dirt and the filter pressure risen to such
a point that it will be necessary to clean your filter.
The function of the filter is to remove suspended matter from the water. It does
not sanitize the water. For sparkling clear water, the water must be sanitized as
well as chemically balanced. Pool chemistry is a specialized area, please consult
your local pool specialist for specific details. In general, proper pool sanitation
requires a free chlorine level of 2 to 4 ppm and a pH range of 7.2 to 7.8. Your
filtration system should be designed to meet your local health codes. As a
minimum, you must be sure that your system will turn over the total volume of
water in your pool at least twice in a 24 hour period.
