Section 2. General Information
This manual contains information for the proper instal-
lation and operation of the Jandy CL and CV Series
Cartridge Filters. Procedures in this manual must be
followed exactly. For technical assistance, contact our
Technical Support Department at 1.800.822.7933.
Cartridge ﬁ lters do not require sand or diatomaceous
earth as the ﬁ lter medium. Instead, the ﬁ lter contains
ﬁ lter elements which are easily removed for cleaning or
Dirty water ﬂ ows into the ﬁ lter tank through the water
line connected to the lower bulkhead (inlet) on the
bottom half of the tank body. It is directed through the
ﬁ lter cartridge inside of the ﬁ lter. The debris is collected
in the ﬁ lter and the clean water ﬂ ows out of the ﬁ lter
through the upper bulkhead (outlet) on the bottom half
of the tank body. Clean water 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 remove the ﬁ lter cartridges and clean them
with soap and water.
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
For best overall performance place the system as
close to the pool as possible.
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.
Protect the ﬁ lter from the weather.
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.
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.
Cartridge Pool Filters - CL and CV Series Filters
The maximum operating pressure for this filter is 50
psi. Never subject the filter to operating pressure
exceeding 50 psi. Operating pressures above 50 psi
can cause product failure or also cause the lid to be
blown off, which can result in death, serious personal
injury, or property dam age.
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.
