SECTION 1. Safety Information

1.1 Important Safety Warning

WARNING - NEVER OPERATE OR TEST THE FILTER SYSTEM AT MORE THAN 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 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.

1.2 General Safety Instructions

ATTENTION INSTALLER:

This manual contains important information about the installation, operation and safe
use of this product. This information should be given to the owner/operator of this
equipment.

1. Before repositioning valve(s) and before beginning the assembly, disassembly or adjustment of the clamp or
any other service of the circulating system (A) turn the pump off and shut off any automatic controls to ensure the
system is not inadvertently started during servicing (B) open the air release valve and (C) wait until all pressure is
relieved (air will have stopped flowing from the air release valve).

2. Whenever installing the filter clamp follow Section 3.4 of this manual, "Clamp Installation".

3. Once service on the circulation system is complete follow Section 4 of this manual, "Start-up and Operation".

4. Maintain the circulation system properly. Replace worn or damaged parts immediately.

5. Be sure that the filter is properly mounted and positioned according to these installation instructions.

6. Do not pressure test above 50 PSI. Pressure testing must be done by a trained pool professional.

7. SAVE THESE INSTRUCTIONS.

SECTION 2. 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

1. See your local pool distributor or dealer for DE type
recommendations. See Table 3 on page 9 for quantity to
be used.

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
with all Jandy filters.

SECTION 3. 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.

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.

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.

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.

CAUTION

Maintain your pressure gauge in good working
order. The pressure gauge is the primary
indicator of how the filter is operating.

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 Valve 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.

4. To mount the pressure gauge/air release assembly to
the top of the filter tank (located in accessory bag):

a. Place the smaller, thicker o-ring onto the threads
of the tank adapter. 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.

b. Place the larger, thinner o-ring onto the gauge
housing. Thread the housing into the coupler on the
tank adapter.
