2.1 Introduction
This manual contains information for the proper
installation and operation of the Jandy® DEL Series
Diatomaceous Earth (DE) Filters. Procedures in this
manual must be followed exactly. To obtain additional
copies of this manual contact us at 707.776.8200 ext.
237. For address information see back cover.
2.2 Description
Dirty water flows 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 into a MPV
(Multiport 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 that 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 at least
two times in a 24 hour period.
2.3 General Requirements
1. For best overall performance locate the filter as
close as possible to the pool.
2. The filter should be located on a level concrete slab
so that the orientation of the valve outlets and 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 other 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. Barell unions are provided
with all Jandy filters.

SECTION 2. General Information
6. The maximum working pressure for this filter is 50 psi.
Never subject the filter to pressure exceeding 50 psi, even
when conducting hydrostatic pressure tests. Pressures
above 50 psi can cause the lid to be blown off.
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
1. See your local pool distributor or dealer for DE type
recommendations. See Table 3 on page 9 for quantity to
be used.
