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.

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 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.

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.

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 ﬁ lter tank. Use the ﬂ 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 efﬁ ciency use the fewest possible number of ﬁ ttings. This will prevent a restriction in the water ﬂ 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 ﬁ 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 ﬁ lter's two (2) or three (3) port diverter valve.

10. Connect the pipes using the unions supplied with the ﬁ lter. Do not use teﬂ on 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 ﬂ ooding 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 ﬁ lter lid onto the lower half, sandwiching the o-ring between the two (2) halves.

2. Holding the ends of the ﬁ lter clamp apart, position the hinged segment of the ﬁ lter clamp over both upper and lower tank ﬂ anges. Bring the ends of the ﬁ 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 ﬁ lter and call a service technician immediately.

WARNING

Follow these instructions carefully. Improper clamp installation can cause product failure or also cause the ﬁ lter lid to be blown off, which can result in death, serious injury, or property damage.

WARNING

NEVER start pump while standing

within ﬁ ve (5) feet of the ﬁ lter. Starting the pump while there is pressurized air in the system can cause product failure or also cause the ﬁ lter lid to be blown off, which can cause death, se ri ous personal injury or property damage.

Caution

Never operate the ﬁ lter in excess of three (3)

minutes without use of diatomaceous earth (DE). DE is the substance that ﬁ lters the water, the ﬁ lter cloth merely supports the DE. Operating without DE will damage ﬁ lter grids and short en ﬁ ltering cycles.

Caution

DO NOT operate the ﬁ lter at water temperatures

above 105° F (40.6° C). Water temperatures above the manufacturer's recommendations will shorten the life span of the ﬁ lter and void the warranty.

5. After the ﬁ rst week of operation, check the clamp and retighten if necessary.

6. Check the ﬁ lter clamp at least once a month.

Figure 7. Filter Clamp Ring Assembly

WARNING

NEVER operate the ﬁ lter system at more

than 50 psi of pressure. Operating ﬁ lter system in excess of 50 psi can cause product failure or also cause the ﬁ lter lid to be blown off, which can cause death, serious personal injury or property damage.

Your ﬁ lter requires diatomaceous earth (DE) for proper ﬁ ltration and operation. The ﬁ lter grids must be precoated with DE in order to protect their surfaces and provide the most efﬁ cient ﬁ ltering action. Refer to Table 2 for the proper quantity of DE to use with your ﬁ lter.

1. Using a one (1) pound coffee can, ﬁ 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 sufﬁ cient water in a separate bucket to make a thin, milky mixture (slurry).

NOTE Excess DE will clog the system. Use amount

speciﬁ ed in this manual.

3. Use the following instructions to coat the ﬁ lter grids.

4.2 Coating the Filter Grids

1. Prepare the recommended amount of DE as outlined in Section 4.1.

2. Start the ﬁ 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 ﬁ 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 ﬁ 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 ﬁ lter valve (two (2) or three (3) port diverter or backwash) to the "FILTER" position.

7. Watch the pressure gauge to be sure that the pressure does not exceed 50 psi in the ﬁ lter for normal operation. If the pressure approaches these limits, turn off the pump and backwash the ﬁ 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 ﬁ 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 ﬁ lter (see Section 6.2).

4.4 Valve Operation

1. The ﬂ ow of water through a DE ﬁ 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 ﬁ lter, it may have all or only some of the positions described in Table 3.

2. Open the pump hair/lint pot lid and ﬁ 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 ﬁ lter isolation valves that were installed in the system and make sure that the ﬁ lter drain plug is in place.

and/or property damage.

6.5 Cleaning Filter Grids with Muriatic Acid

1. Check with your local pool store or service company to see if they offer ﬁ lter grid de-scaling services.

2. Stiffening of the ﬁ 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 ﬁ lter grids in a plastic tub or pail with six (6) parts water to one (1) part hydrochloric acid (muriatic acid).

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 ﬁ lter/pump system. For technical assistance, contact our Technical Support Department at 1.800.822.7933

3. Wear rubber gloves and eye protection when mixing the solution, and handling or rinsing the ﬁ lter grids.

4. Soak for at least four (4) hours.

5. Rinse the ﬁ lter grids thoroughly with water.

6. See Sections 5.1 and 5.2 for reassembly of the ﬁ lter tank and ﬁ 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 ﬂ ow to all ports.

3. Remove the drain plug at the base of the ﬁ 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.
