Section 2. General Information
2.1
Introduction
This manual contains information for the proper installation
and operation of the DEV Jandy Diatomaceous Earth (DE)
Filters. Procedures in this manual must be followed exactly.
For technical assistance, contact our Technical Support
Department at 1.800.822.7933.
2.2
Description
Dirty water flows into a two or three port diverter valve,
then into the filter through the lower bulkhead on the
bottom of the tank and is directed through the DE grids.
The debris is collected on the surface of the grids as the
water flows through them. The clean water is directed
into the manifold, then through the outlet tube, and
finally, out of the filter through the upper bulkhead
on the bottom half of the tank. The filtered water then
goes through the two or three port diverter valve and is
returned through the piping system to the pool.
As debris collects in the filter, the pressure will rise
and water flow to the pool will diminish. The filter will
eventually become so plugged with debris that it will
be necessary to perform the backwash procedure. It
is important to know when to backwash the filter. See
Section 6 for further discussion of backwashing the filter.
NOTE
A filter removes dirt and other suspended particles
but does not sanitize the pool. Pool water must be
sanitized and chemically balanced for clear water.
The filtration system should be designed to meet
local health codes. At a minimum, the system should
turnover the total volume of water in your pool two to
four times in a 24-hour period.
2.3
General Requirements
1.
For best overall performance, place the system as
close to the pool as possible.
2.
The filter should be located on a level concrete
slab so that the orientation of the valve outlets and
the pressure gauge are convenient and accessible
for the installation and operation of the unit.
3.
Protect the filter from the weather.
4.
If fitting a chlorinator and/or any other device
into the filtration plumbing circuit, great care
must be exercised to ensure that the appliance is
installed in accordance with the Manufacturer's
Instructions and any standards that may exist.
5.
We recommend the use of barrel unions to connect
each component of the water conditioning system
to ease in future servicing. Barrel unions are
provided with all Jandy filters.

WARNING
The maximum working pressure for this filter is 50 psi.
Never subject the filter to working pressure exceeding
50 psi. Working pressures above 50 psi can cause
product failure or also cause the filter lid to be blown
off, which can result in death, serious personal injury,
or property damage
6.
When performing hydrostatic pressure tests or
when testing for external leaks of the completed
filtration and plumbing system, ensure that the
maximum pressure the filtration system is subjected
to does not exceed the maximum working pressure
of any of the components within the system.
2.4
DE Requirements
See your local pool distributor or dealer for DE type
recommendations. See Table 2 on page 10 for the amount
of DE to be used.
