General Information
2.1 Introduction
This manual contains information for the proper
installation and operation of the Jandy® DEL Series
Diatomaceous Earth (DE) Filters. Procedures in this manual
must be followed exactly . To obtain additional copies of this
manual contact us at 707.776.8200 ext. 237. For address
information see back cover.
2.2 Description
Dirty water flows 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 into a
MPV (Multiport 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 that 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 at least two times in a 24 hour
period.
6. 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.
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

2.3 General Requirements
1 . For best overall performance locate the filter as
close as possible to the pool.
2. The filter should be located on a level concrete slab so
that the orientation of the valve outlets and 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 exercised
to ensure that the appliance is installed in accordance
with the Manufacturer’s Instructions and any other
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. Barell unions are provided

Installation Instructions
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. Install the filter 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 Fig. 3).
5 . Allow sufficient space above the filter to remove the
filter lid for cleaning and servicing.
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.
3.2 Filter Preparation
1 . Check carton for any 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.
4. A visual inspection of all parts should be made now.
See parts list on pages 14 and 15.
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.
Caution
!
Maintain your pressure gauge in good working
order. The pressure gauge is the primary
indicator of how the filter is operating.

!
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.
3.3 Filter Installation
1. This filter operates under pressure. When clamped
properly and operated without air in the water
system, this filter will operate in a safe manner.
2. If doubt exists as to the pressure which the system
will be subjected to, install an ASME approved
automatic Pressure Relief V alve or Pressure Regulator
in the circulation system set to the lowest working
pressure of any of the components in the system .
3 . Place the filter on the concrete pad. Line the filter up
with the inlet/outlet pipes (see Fig. 4). Remove the
shipping screw.

5 . T o 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. T o 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 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.
Figure 4. Filter Location
9. Support the inlet/outlet pipes independently to
prevent any undue strains on the filter MPV.
10. Connect the pipes using the unions supplied with
the MPV . Do not use teflon tape or pipe dope on any
unions. Assemble the unions dry and hand tighten.
11. Be sure that all provisions for waste water disposal
meet local, state or national codes. One hundred
gallons or more of pool water will be discharged during
filter backwashing. Do not discharge water where it
will cause flooding or damage.

Start-Up and Operation
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 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. Starting the pump while there
is pressurized air in the system can cause the
filter lid to be blown off, which can cause death,
serious personal injury or property damage.
Warning
!
Changing the multiport valve handle while there
is pressurized air in the system can cause the
filter lid to be blown off, which can cause death,
serious personal injury or property damage.
4.1 Preparing Diatomaceous Earth
Y our 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 T able 3 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.
Table 3. DE Slurry Mixture
Model DE Quantity No. of 1 lb.
Number (lbs.) (kg.) coffee cans
DEL48 5.0 2.0 10
DEL60 6.0 2.7 12
4.2 Coating the Filter Grids
1 . Prepare recommended amount of DE as outlined in
Section 4.1.
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 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. Operat ing without DE will damage filter grids and
shorten filtering cycles.
Caution
!
DO NOT operate filter at water temperatures
above 120° F (65.5° C). Water temperatures
above the manufacturer's recommendations will
shorten the life span of the filter, and void the
warranty.
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 of 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.
Page 10
4.3 New Pool and Seasonal Start-Up
1 . Set the filter valve (MPV or backwash) to the
"FIL TER" 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 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.

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 13 to identify possible causes and
solutions.
9. 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).
4.4 V alve Operation
1 . The flow of water through a DE filter iscontrolled by
an optional backwash valve or multiport valve (MPV).
2. The handle on top of the backwash valve or MPV can
be moved to different positions. The function of each
position is described below (see Fig. 7).
Note: Depending on the model of backwash valve or
MPV installed with your filter, it may have all or only
some of the positions described below
Figure 7. Multi Port Valve Handle Positions
SECTION 5.

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).
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
