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® 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 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 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 flows into a two or three port diverter valve,
then into the filter 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 flows through them. The clean water is directed
into the manifold, then through the outlet tube, and
finally, out of the filter through the upper bulkhead
on the bottom half of the tank. The filtered 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 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 perform the backwash procedure. It is
important to know when to backwash the filter. See Section 6 for further discussion of backwashing 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.
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
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.
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.

7.
If the filter needs to be located above the water
level of the pool, it can be raised 2.5 ft. without
affecting the pump efficiency. A check valve is
recommended on the suction line to the pump.
8.
If the filter 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
flow of pool water during any routine servicing
that may be required.
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 flood
when it rains. Damp, non-ventilated areas should
be avoided.
2.
Provide solid mounting for the filter 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 filter as the sand will wash
away. Filters, once loaded with media, can weigh
up to 800 lbs.
3.
Install electrical controls at least five (5) feet from
the filter. This will allow enough room to stand
away from the filter during start-up.
4.
Allow sufficient clearance around the filter to
permit a visual inspection of the clamp ring.
See Figure 2.
5.
Allow sufficient space above the filter to remove
the filter lid and filter element for cleaning and
servicing.
6.
Position the filter 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.
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 filter 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 filter. (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 filter 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 filter components are
damaged, notify carrier immediately.
2.
Carefully remove the accessory package.
3.
With the carton in an upright position, remove the
filter tank from the carton.
CAUTION
Maintain your pressure gauge in good working order.
The pressure gauge is the primary indicator of how
the filter is operating.
CAUTION

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 filter tank. Use the flats on the tank
adapter to tighten. Do not overtighten.
Place the larger, thinner o-ring onto the
gauge housing. Thread the housing into the
coupler on the tank adapter.
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 efficiency use the fewest possible number
of fittings. This will prevent a restriction in the
water flow.
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 filter tank
or loss of prime at the pump. Pump discharge line
leaks may show up as dampness or jets of water.
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 filter lid onto the lower half, sandwiching the
o-ring between the two (2) halves.
2.
Holding the ends of the filter clamp apart, position
the hinged segment of the filter clamp over both
upper and lower tank flanges. Bring the ends of the
filter 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 filter 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.
Page 8
WARNING
Changing the two (2) or three (3) port diverter valve
handle while there is pressurized air in the system

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.
Your filter requires diatomaceous earth (DE) for
proper filtration and operation. The filter grids must
be precoated with DE in order to protect their surfaces and provide the most efficient filtering action.
Refer to Table 2 for the proper quantity of DE to use
with your filter.
1. Using a one (1) pound coffee can, fill the can
with diatomaceous earth (DE). Do not pack or
compress the DE into the can.
2.
Mix the required amount of DE with sufficient
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 filter
grids.

7.
Watch the pressure gauge to be sure that the
pressure does not exceed 50 psi in the filter for
normal operation. If the pressure approaches these
limits, turn off the pump and backwash the filter
(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 filter 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 filter (see Section 6.2).
4.2 Coating the Filter Grids
2.
Start the filter 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 filter.
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 filter 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
Set the filter valve (two (2) or three (3) port
diverter or backwash) to the "FILTER" position.
2.
Open the pump hair/lint pot lid and fill 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 filter isolation valves that
were installed in the system and make sure that the
filter 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 filter, or the filter has just been
backwashed, add the DE slurry as described in
section 4.2.
1.
The flow of water through a DE filter 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.

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.
With the filter 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 filter and start the pump to
circulate the water backwards through the filter 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 filter pump off.
7.
Follow the procedure for coating the filter grids as
described in Section 4.2.
6.3 Pressure Gauge
1.
During operation of the filtration 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 filter/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 filter tank. Close the filter
isolation valves. Remove the drain plug.
2.
Once all pressure has been relieved, remove the
clamp ring and the filter lid. Inspect the o-ring for
cracks or tears and replace if necessary.
3.
Remove the filter grid assembly from the filter.
Follow the instructions in Section 5.1.
4.
Using a garden hose, thoroughly flush all
contaminates from the filter grid surfaces.

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 filter tank
and filter grids.
6.5 Cleaning Filter Grids with Muriatic Acid
1.
Check with your local pool store or service
company to see if they offer filter grid de-scaling
services.
2.
Stiffening of the filter 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 filter 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
filter grids.
4.
Soak for at least four (4) hours.
5.
Rinse the filter grids thoroughly with water.
6.
See Sections 5.1 and 5.2 for reassembly of the
filter tank and filter 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 flow to all ports.
3.
Remove the drain plug at the base of the filter 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.
