Section 2. General Information
2.1 Introduction
This manual contains information for the proper
installation and operation of the Jandy DEV Series
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 fl ows into a two or three port diverter valve,
then into the fi lter 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 fl ows through them. The clean water is directed
into the manifold, then through the outlet tube, and
fi nally, out of the fi lter through the upper bulkhead
on the bottom half of the tank. The fi ltered 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 fi lter, the pressure will rise
and water fl ow to the pool will diminish. The fi lter 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 fi lter. See Sec-
tion 6 for further discussion of backwashing the fi lter.
NOTE
A fi lter removes dirt and other suspended particles
but does not sanitize the pool. Pool water must be
sanitized and chemically balanced for clear water.
The fi ltration 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 fi lter 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 fi lter from the weather.
4.
If fi tting a chlorinator and/or any other device into
the fi ltration 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 fi lters.
WARNING
The maximum working pressure for this fi lter is 50 psi.
Never subject the fi lter to working pressure exceeding
50 psi. Working pressures above 50 psi can cause
product failure or also cause the fi lter lid to be blown
off, which can result in death, serious personal injury,
or property dam age
6.
When performing hydrostatic pressure tests or
when testing for external leaks of the completed
fi ltration and plumbing system, ensure that
the maximum pressure the fi ltration 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.
