Section 1. Safety Information
1.1 Important Safety Warning
WARNING
• Do not connect system to an unregulated city water system or other external source of
pressurized water producing pressures greater than 35 PSI.
• Pressurized air in system 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 damage. Be sure all air is out of
system before operating or testing the equipment.
WARNING
MAXIMUM OPERATING PRESSURE OF THE FILTER IS 50 PSI. NEVER SUBJECT THE FILTER
TO ANY OPERATING PRESSURE EXCEEDING 50 PSI.
This filter operates under high pressure. When any part of the circulating system, i.e., filter, pump,
valve(s), clamp, etc. is serviced, air can enter the system and become pressurized when the system
is restarted. Pressurized air can cause product failure or also cause the filter lid to be blown off which
can result in death, serious personal injury or property damage. To avoid this po ten tial haz ard, fol low
all of the in struc tions in this man u al.
WARNING
To minimize risk of severe injury or death the filter and/or pump should not be subjected to the piping
system pressurization test.
Local codes may require the pool piping system to be subjected to a pressure test. These
requirements are generally not intended to apply to the pool equipment such as filters or pumps.
®
Jandy
If however this WARNING cannot be followed and pressure testing of the piping system must include
the filter and/or pump BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS:
• Check all clamps, bolts, lids, lock rings and system accessories to ensure they are properly
• RELEASE ALL AIR in the system before testing.
• Water pressure for test must NOT EXCEED 35 PSI.
• Water temperature for test must NOT EXCEED 100°F (38°C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready for operation.

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.
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.

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.

Section 3. Installation Instructions
WARNING
Use equipment only in a pool or spa installation.
Do not connect system to an unregulated city water
system or other external source of pressurized water
producing pressures greater than 35 psi.
3.1 Filter Location
1. Select a well-drained area, one that does not fl ood
when it rains. Damp, non-ventilated areas should
be avoided.
2. Provide solid mounting for the fi lter and pump
system. Install system on a concrete slab or solid
concrete blocks to avoid risk of settlement. Do not
use sand to level the fi lter as the sand will wash
away. Filters, once loaded with media, can weigh
up to 800 lbs.
3. Install electrical controls at least fi ve (5) feet from
the fi lter. This will allow enough room to stand
away from the fi lter during start-up.
4. Allow suffi cient clearance around the fi lter to
permit a visual inspection of the clamp ring.
See Figure 2.
5. Allow suffi cient space above the fi lter to remove
the fi lter lid and fi lter element for cleaning and
servicing.
6. Position the fi lter to safely direct water drainage.
Align the air release valve to safely direct
pressurized purged air or water.
WARNING
Water discharged from an improperly positioned fi lter
or valve can create an electrical hazard which can
cause death, serious injury or property damage.
CAUTION
Maintain your pressure gauge in good work ing order.
The pressure gauge is the primary indicator of how
the fi lter is operating.
7. If the fi lter needs to be located above the water
level of the pool, it can be raised 2.5 ft. without
affecting the pump effi ciency. A check valve is
recommended on the suction line to the pump.
8. If the fi lter is to be installed below the water level
of the pool, isolation valves should be installed on
both the suction and return lines to prevent back
fl ow of pool water during any routine servicing
that may be required.
3.2 Anchor Bracket Installation
In Florida, building codes require that all appliances
be securely fastened to the equipment pad in order to
withstand high wind pressures created by hurricanes.
Zodiac Pool Systems, Inc. provides an anchor bracket
kit for this purpose. Please see the Parts List in Section
9 of this manual for the correct part number.
NOTE Anchor screws and washers are not included
with the fi lter or the anchor bracket kit. Zodiac
recommends that a ¼" x 2¼" long stainless
steel Tapcon® type concrete screw be used to
mount the anchor bracket to the equipment pad.
The Tapcon type concrete screw meets Florida
buliding code requirements.
After placing the fi lter on the equipment pad, as outlined
in Section 3.1, drill a 5/32" hole in the concrete at each
of the four (4) brackets on the fi lter. (The correct size
drill bit is usually provided with the concrete screws
when purchased.)
Install the Tapcon screws and washers through each of
the four (4) anchor brackets to secure the fi lter to the
equipment pad. See Figure 3. Do not over-torque the
screws.
3.3 Filter Preparation
1. Check carton for damage due to rough handling
in shipment. If carton or any fi lter components are
damaged, notify carrier immediately.
2. Carefully remove the accessory package.
3. With the carton in an upright position, remove the
fi lter tank from the carton.
