Section 2. General Information
2.1 Introduction
This manual contains information for the proper instal-
lation and operation of the Jandy
Procedures in this manual must be followed exactly.

2.2 Description
Cartridge filters do not require sand or diatomaceous
earth as the filter medium. Instead they contain a filter
cartridge element which is easily removed for cleaning
or replacement.
Dirty water flows into the filter tank and is directed
through the filter cartridge. The debris is collected on
the surface of the cartridge as the water flows through
it. The water will travel through the central filter core
towards the bottom of the filter into the lower manifold.
Clean water is returned to the swimming pool through
the filter outlet port at the tank's bottom.
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 remove the filter cartridge and clean it (see
Section 6 "Cleaning 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
xercised to ensure that the appliance is installed in
accordance with the Manufacturer's Instructions
and any standards that may exist.

5.
Use barrel unions to connect each component of
the water conditioning system for future servicing.
All Jandy filters come with these type of fittings.
WARNING
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.
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.
