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 filter 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
potential hazard, follow all of the instructions in this manual.
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 Pro Series pool equipment is pressure tested at the factory.
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 installed
and secured before testing.
• 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.
Notice: These parameters apply to Jandy Pro Series equipment only. For non-Jandy equipment, consult
equipment manufacturer.

Section 2. General Information
2.1 Introduction
This manual contains information for the proper installation
and operation of the DEV Jandy 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 ows into a two or three port diverter valve,
then into the 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 ows through them. The clean water is directed
into the manifold, then through the outlet tube, and
nally, out of the lter through the upper bulkhead
on the bottom half of the tank. The 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 lter, the pressure will rise
and water ow to the pool will diminish. The 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 lter. See
Section 6 for further discussion of backwashing the lter.
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 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 lter from the weather.
4. If tting a chlorinator and/or any other device
into the 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 lters.
WARNING
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 damage
6. When performing hydrostatic pressure tests or
when testing for external leaks of the completed
ltration and plumbing system, ensure that the
maximum pressure the 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.

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 ood
when it rains. Damp, non-ventilated areas should
be avoided.
2. The lter should be installed on a rm, solid, and
level surface or platform to avoid risk of settlement.
Do not use sand to level the lter as the sand will
wash away; lter systems can weight up to 800
pounds once loaded with media. Check local
building codes for additional requirements. (Ex.
Equipment pads in Florida must be concrete and
equipment must be secured to the pad.)
3. Install electrical controls at least ve (5) feet from
the lter. This will allow enough room to stand
away from the lter during start-up.
4.
Allow sufcient clearance around the lter to permit
a visual inspection of the clamp ring. See Figure 2.
5. Allow sufcient space above the lter to remove
the lter lid and lter element for cleaning and
servicing.
6. Position the 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 filter
or valve can create an electrical hazard which can
cause death, serious injury or property damage.
CAUTION
Maintain your pressure gauge in good working order.
The pressure gauge is the primary indicator of how the
filter is operating.
7. If the lter needs to be located above the water
level of the pool, it can be raised 2.5 ft. without
affecting the pump efciency. A check valve is
recommended on the suction line to the pump.
8. If the 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
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
filter 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 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 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 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 lter components are
damaged, notify carrier immediately.
2. Carefully remove the accessory package.
3. With the carton in an upright position, remove the
lter tank from the carton.
CAUTION
DO NOT move the filter tank without the shipping
screw in place or the filter grids may be damaged while
installing the filter tank.
4. A visual inspection of all parts should be made
now. See the parts list on page 15.

WARNING
To avoid an electrical shock hazard, which can result
in serious injury or death, ensure that all electrical
power to the system is turned off before approaching,
inspecting or troubleshooting any leaking valves
or plumbing that may have caused other electrical
devices in the surrounding area to get wet.
1. This lter operates under pressure. When clamped
properly and operated without air in the water
system, this lter will operate in a safe manner.

Page 8 ENGLISH Jandy®DE Pool Filters |Installation & Operation Manual
Figure 5. Pressure Gauge/Air Release Assembly
a. Place the smaller, thicker o-ring onto the
threads of the tank adapter, see Fig. 5. Slide the
tank adapter through the coupling nut and into
the lter tank. Use the ats on the tank adapter
to tighten. Do not overtighten.
b. Place the larger, thinner o-ring onto the gauge
housing. Thread the housing into the coupler
on the tank adapter.
c. Orient the gauge/air release assembly in the
desired position. Raise and thread the locknut
onto the bottom of the gauge/air release
assembly. Hand tighten the nut only. Using a
wrench to tighten the nut may damage the nut,
gauge or air release assembly.
5. To reduce pressure losses, 2" (minimum) piping is
recommended for plumbing the system.
6. For best efciency use the fewest possible
number of ttings. This will prevent a restriction
in the water ow.
7. Make all plumbing connections in accordance
with local plumbing and building codes. Filter
connections are provided with an o-ring seal. To
avoid damage to the o-rings, use only a silicone
base lubricant on the o-rings. Do not use pipe
joint compound, glue or solvent on inlet/outlet
union coupling nuts.
8. Keep piping tight and free of leaks. Pump suction
line leaks may cause air to be entrapped in lter
tank or loss of prime at the pump. Pump discharge
line leaks may show up as dampness or jets of
water.
9. Support the inlet/outlet pipes independently to
prevent any undue strains on the lter's two (2) or
three (3) port diverter valve.
10. Connect the pipes using the unions supplied with
the lter. Do not use teflon tape or pipe dope on
any unions. Assemble the unions dry and hand
tighten.
CAUTION
Be sure that all provisions for wastewater disposal
meet local, state or national codes. During any
backwashing or draining process, 100 gallons or more
of pool water will be discharged. Do not discharge
water where it will cause flooding or damage.
3.5 Clamp Installation, DEV Series
1. Be certain that the o-ring seat is clean and that the
o-ring is in position in the lower tank half. Press
the lter lid onto the lower half, sandwiching the
o-ring between the two (2) halves.
2. Holding the ends of the lter clamp apart, position
the hinged segment of the lter clamp over both
upper and lower tank anges. Bring the ends of
the lter clamp together.
3. Place the "T" nut and threaded rod assembly into
the clamp. Be sure the "T" nut is seated in the
clamp in the proper orientation. See Figure 6.
4. Use a 9/16" socket on the tightening nut until
the clamp ring halves touch each other, or are
within 1/16", see Fig. 7 but do not overtighten
as the clamp can break. If unable to tighten
as indicated, do not operate the lter and call a
service technician immediately.
WARNING
Follow these instructions carefully.
Improper clamp installation can
cause product failure or also cause
the filter lid to be blown off, which
can result in death, serious injury, or
property damage.
WARNING
NEVER start pump while standing
within five (5) feet of the filter. Starting
the pump while there is pressurized
air in the system can cause product
failure or also cause the filter lid to
be blown off, which can cause death,
serious personal injury or property
damage.

WARNING
NEVER operate the filter system
at more than 50 psi of pressure.
Operating filter system in excess of
50 psi can cause product failure or
also cause the filter lid to be blown
off, which can cause death, serious
personal injury or property damage.
WARNING
Changing the two (2) or three (3) port diverter valve
handle while there is pressurized air in the system can
cause product failure or also cause the filter lid to be
blown off, which can cause death, serious personal
injury or property damage.
CAUTION
Dust released during normal handling of diatomaceous
earth can cause eye and respiratory irritation.
Prolonged breathing of excess concentrations of dust
may cause lung damage.
CAUTION
Never operate the filter in excess of three (3) minutes
without use of diatomaceous earth (DE). DE is the
substance that filters the water, the filter cloth merely
supports the DE. Operating without DE will damage
filter grids and shorten filtering cycles.
CAUTION
DO NOT operate the filter at water temperatures
above 105° F (40.6° C). Water temperatures above the
manufacturer’s recommendations will shorten the life
span of the filter and void the warranty.
5. After the rst week of operation, check the clamp
and retighten if necessary.
6. Check the lter clamp at least once a month.
Section 4. Start-Up and
Operation
4.1 Preparing Diatomaceous Earth
Your lter requires diatomaceous earth (DE) for proper
ltration and operation. The lter grids must be precoated
with DE in order to protect their surfaces and provide
the most efcient ltering action. Refer to Table 2 for the
proper quantity of DE to use with your lter.
1. Using a one (1) pound coffee can, ll the can
with diatomaceous earth (DE). Do not pack or
compress the DE into the can.
2. Mix the required amount of DE with sufcient
water in a separate bucket to make a thin, milky
mixture (slurry).
NOTE Excess DE will clog the system. Use amount specified
in this manual.
3. Use the following instructions to coat the lter
grids.

4.2 Coating the Filter Grids
1. Prepare the recommended amount of DE as
outlined in Section 4.1.
2. Start the lter system as outlined in Section 4.3.
3. With the pump running and the pool skimmer
valve open, slowly pour the mixture directly into
the pool's skimmer basket. The slurry will be
drawn into the lter.
4. After coating grids, rotate the bezel of the
pressure gauge so that the arrow next to the word
"CLEAN" is aligned with the needle of the gauge.
This marks the original starting pressure of the
system.
5. Clean the lter when the pressure of the system
increases so that needle of the gauge aligns with
the arrow next to the word "DIRTY" on the bezel
of the gauge. This indicates an increased pressure
of between 10 and 12 psi above original starting
pressure.
4.3 New Pool and Seasonal Start-up
1. Set the lter valve (two (2) or three (3) port
diverter or backwash) to the "FILTER" position.
2. Open the pump hair/lint pot lid and ll the pump
basket with water to prime the system. Replace
the lid. (You may have to do this several times on
new and seasonal start-ups.)
3. Completely open the air release valve on the
gauge/air release assembly by turning the knob on
the back of the assembly fully counterclockwise
(do not remove the knob).
4. Be sure to open any lter isolation valves that
were installed in the system and make sure that
the lter drain plug is in place.
5. Stand clear of the filter and start the pump to
circulate water through the system. When a steady
stream of water starts to come out of the air
release valve, close the valve.
6. If this is a new lter, or the lter has just been
backwashed, add the DE slurry as described in
section 4.2.
7. Watch the pressure gauge to be sure that the
pressure does not exceed 50 psi in the lter for
normal operation. If the pressure approaches
these limits, turn off the pump and backwash the
lter, see Section 6.2. If the pressure remains high
after backwashing and reapplying the DE slurry,
refer to the troubleshooting guide on page 14 to
identify possible causes and solutions.
8. After the pressure gauge has stabilized, turn the
bezel ring so that the arrow next to the word
"CLEAN" aligns with the needle of the gauge. As
the lter cleans the water, the grids will clog over
time, and the pressure will increase. When the
needle of the pressure gauge aligns with the arrow
next to the word "DIRTY" on the bezel ring, it is
time to backwash the lter. See Section 6.2.
4.4 Valve Operation
1. The ow of water through a DE lter is controlled
by an optional backwash valve or two (2) or three
(3) port diverter valve.
2. The handle on top of the backwash valve or
diverter valve can be moved to different positions.
The function of each position is described below.
See Figure 8.
NOTE Depending on the model of backwash valve or diverter
valve installed with your filter, it may have all or only
some of the positions described in Table 3.

8. While the DE lter grid assembly is out of the
lter tank, rinse the inside of the tank with water.
Replace drain plug.
9. Gently rinse the grids with water. After cleaning
the lter grids, place the grid assembly back into
the lter tank bottom. See Sections 6.4 and 6.5 for
further grid cleaning instructions.
10. Replace the tank o-ring and tank lid.
11. Reinstall the tank clamp ring. See Section 3.5 for
tank clamp ring installation.
12. If applicable, open the valves closed in step 4.
5.2 Filter Grid Disassembly/Assembly
1. Remove the complete grid assembly by following
the instructions in Section 5.1, steps 2-6.
2. Remove the manifold by rst unscrewing the tie
rod knob in the center of the manifold. Then lift
the manifold assembly off of the grids and the
outlet tube.
3. Remove the top spacer from the grids.
4. The individual lter grids can now be removed
from the grid support. Use care to avoid damaging
the grids.
5. See Figure 8 for the arrangement of lter grids in
the lter grid assembly.
6. To reassemble the lter grid assembly, arrange the
lter grids into position on the bottom plate, see
Fig. 9. Use the plastic top spacer to hold the grids
in place.
WARNING
NEVER attempt to assemble,
disassemble or adjust the filter when
there is pressurized air in the system.
Starting the pump while there is any
pressurized air in the system can
cause product failure or also cause
the filter lid to be blown off, which can
cause death, serious personal injury
or property damage.

6.2 Backwashing
1. With the lter pump off, set the backwash valve
or diverter valve handle to the "BACKWASH"
position.
CAUTION
Maintain your pressure gauge in good working order.
The pressure gauge is the primary indicator of how the
filter is operating.
2. Open the air release valve.
3. Stand clear of the lter and start the pump to
circulate the water backwards through the lter to
the waste line.
4. When a steady stream of water is expelled
through the air release valve, close the valve.
5. Run the pump until the backwash discharge water
is clear (repeat steps 1 thru 5 if required).
6. Switch the lter pump off.
7. Follow the procedure for coating the lter grids as
described in Section 4.2.
6.3 Pressure Gauge
1. During operation of the ltration system, check
the pressure gauge/air release assembly for air or
water leaks at least once a week.
2. Keep the pressure gauge in good working order.
If you suspect a problem with the gauge, Zodiac®
recommends that you call a service technician to
do any work on the lter/pump system.
6.4 Cleaning the Filter Grids with Water
1. Turn off the pump and switch off the circuit
breaker to the pump motor. Open the air release
valve on top of the lter tank. Close the lter
isolation valves. Remove the drain plug.
2. Once all pressure has been relieved, remove the
clamp ring and the lter lid. Inspect the o-ring for
cracks or tears and replace if necessary.
3. Remove the lter grid assembly from the lter.
Follow the instructions in Section 5.1.
4. Using a garden hose, thoroughly ush all
contaminates from the lter grid surfaces.
9. Place the tie rod knob on the tie rod and tighten.
Tighten until the lter grid assembly is snug.
Do not overtighten.
10. Reassemble the tank o-ring and tank lid.
11. Reinstall the tank clamp ring. See Section 3.5 for
clamp installation.
Section 6. Maintenance
6.1 General Maintenance
1. Wash outside of lter with a mild detergent
and water. Rinse off with a hose. Do not use
solvents to clean the filter. Solvents will
damage the plastic components of the filter.
2. Inspect the DE lter grids at least twice a year.
Remove any foreign material that has not been
backwashed out of the system.
3. Check pressure during operation at least once a
week.
4. Remove any debris from the pumps and pool
skimmer baskets.
5. Check pump and lter for any leaks. If any leaks
develop, turn off the pump and call a pool
service technician.
6. Product safety signs or labels should be
periodically inspected and cleaned by the product
user as necessary to maintain good legibility for
safe viewing distance.
7. Product safety signs or labels should be replaced
by the product user when a person with normal
vision, including corrected vision, is no longer
able to read the safety signs or label message
panel text at a safe viewing distance from
the hazard. In cases where the product has an
extensive expected life or is exposed to extreme
conditions, the product user should contact either
the product manufacturer or some other source to
determine means for obtaining replacement signs
or labels.
CAUTION
Be sure that all provisions for wastewater disposal
meet local, state or national codes. One hundred
gallons (100 gals.) or more of pool water will be
discharged during filter backwashing. Do not discharge
water where it will cause flooding or damage.
8. Installation of new replacement safety signs or
labels should be in accordance with the sign or
label manufacturer's recommended procedure.

WARNING
Working with muriatic acid can be dangerous. When
cleaning filter grids, always wear rubber gloves and
eye protection. Add acid to water, do not add water
to acid. Splashing or spilling acid can cause severe
personal injury and/or property damage.
5. See Section 5.2 for reassembly of the lter tank
and lter grids.
6.5 Cleaning Filter Grids with Muriatic
Acid
1. Check with your local pool store or service
company to see if they offer lter grid de-scaling
services.
2. Stiffening of the lter grid fabric is caused by
mineral deposit buildup. It is usually due to
deposits of either magnesium, calcium, alkalines
or carbonates. Removal of these deposits may
be accomplished by soaking the lter grids in a
plastic tub or pail with six (6) parts water to one
(1) part hydrochloric acid (muriatic acid).
3. Wear rubber gloves and eye protection when
mixing the solution, and handling or rinsing the
lter grids.
4. Soak for at least four (4) hours.
5. Rinse the lter grids thoroughly with water.
6. See Sections 5.1 and 5.2 for reassembly of the
lter tank and lter grids.
Section 7. Winterizing
1. Turn off the pump and circuit breakers.
2. Open the air release valve and move the diverter
valve handle to a position between two (2) ports.
This will allow air to ow to all ports.
3. Remove the drain plug at the base of the lter to
ensure that the tank is empty. Store the drain plug
and seal it in a safe place. Do not reinstall until
next season at start-up.
4. Drain system piping of all water.
5. Cover the system with a tarpaulin or plastic sheet
to protect it from the weather.
Section 8. Troubleshooting
1. For a list of common problems and solutions, see
the Troubleshooting Guide on the following page.
2. Zodiac®recommends that you call a service
technician to do any work on the lter/pump
system. For technical assistance, contact our
Technical Support Department at 1.800.822.7933.
