Section 2. General Information
2.1 Introduction
This manual contains information for the proper
installation and operation of the Jandy JS Series Sand
Filters. Procedures in this manual must be followed
exactly. This manual may also be downloaded from our
website, www.jandy.com. For additional contact infor-
mation, please see the back cover of this manual.
2.2 Description
Jandy high rate sand filters most commonly
use sand as a filter medium, or sand over a shallow
layer of pea gravel. A filter medium other than sand is
sometimes used as described in Section 3.6.
Dirty water flows into the filter tank through
the water line connected to the lower bulkhead fitting
(inlet) on the side of the filter. The water is directed
through a diffuser(s) in the water space above the sand
bed surface. As the water flows through the filter, debris
and large particles are deposited on the surface of the
sand bed, and finer particles are collected throughout
the body of sand. Clean water flows through the laterals
(spokes) at the bottom of the sand bed and out of the
filter through the upper bulkhead fitting (outlet) on the
side of the filter.
As debris and dirt particles collect in the filter,
the pressure will rise (indicated by the pressure gauge
on the top of the filter) and water flow to the pool
will diminish. The filter will eventually become so
clogged with debris that it will be necessary to perform
a backwash procedure to cleanse the filter. Backwash-
ing instructions are provided in Section 5.1, "Filter
Cleaning Instructions".
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 (2) to four
(4) times in a 24 hour period.

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 dam age

For best overall performance place the system as
close to the pool as possible.
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.
Protect the filter from the weather.
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.
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
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.
