SAFETY INFORMATION

Important Safety 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 dial valve 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.

MAXIMUM OPERATING PRESSURE OF THE FILTER IS 35 PSI. NEVER SUBJECT THE FILTER TO ANY OPERATING PRESSURE
EXCEEDING 35 PSI.

• This fi lter operates under high pressure. When any part of the circulating system, i.e., fi lter, pump, valve(s), 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 dial valve 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.

To minimize risk of severe injury or death the fi lter 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 fi lters 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 fi lter 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.

SAFETY INFORMATION

Important Safety 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.

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

To avoid electrical shock hazard, which can result in serious injury or death, ensure that all electrical 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.

Creating high vacuum levels can cause the tank vessel to crack and leak with the potential for property damage.

Be sure that all provisions for wastewater disposal meet local, provincial 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.

To avoid damaging the laterals (spokes), slowly add the fi lter media until the laterals are fully covered. Cracked or broken laterals (spokes)
will cause sand to be discharged to the pool.

Improper dial valve installation can cause product failure or also cause the fi lter dial valve to be blown off, which can result in death, serious
personal injury, or property damage.

Never attempt to adjust or remove the dial valve when the pump is running or there is pressure in the system. This can cause product failure or
also cause the dial valve to be blown off which can result in death, serious personal injury, or property damage.

The fi lter module is equipped with a dial valve which works as follows:

1). FILTER gives a downward fl ow through the fi lter bed. Dirt accumulates in the
sand as fi ltering proceeds, and gradually restricts the fl ow of water until back­washing is necessary. This position can also be used for vacuuming.

2). BACKWASH gives an upward fl ow through the fi lter bed that removes the dirt
from the sand and carries it to the waste.

3). DRAIN is for pumping water from the pool. It allows the fl ow from the pump to
bypass the fi lter and go directly to the waste. You can also use this position to
vacuum heavy concentrations of debris.

4). WHIRLPOOL bypasses the fi lter to obtain the optimum performance from a
hydro-air fi tting fed by the fi lter pump. (No fi ltration occurs in this position).

5). WINTERIZE allows air to leave or enter the tank to help priming and draining.
Only to be used when pump is off.

6). RINSE gives a downward fl ow that settles the fi lter bed after backwashing and
carries any remaining loose dirt to the waste.

7). TEST prevents only backfl ow of water from pool during pump maintenance if
fi lter is below water level.

FILTER SAND

The outstanding fi ltration and superior dirt-holding capacity of this fi lter depends
on the use of the proper grade of fi lter sand. It should meet the following specifi ca­tions: The fi lter sand must be free of clay, loam, dirt and organic matter, and must
consist of hard, durable, rounded or sub-angular grains of silica sand with no more
than 1% of fl at or micaceous particles. The grains should have an effective size of

0.44mm with a uniformity coeffi cient of 1.35. DO NOT USE “SANDBOX” SAND. The
fi lter sand is NOT included in the fi lter module and must be purchased separately.
Refer to the table for the quantity required. Do not fi ll the tank with sand before
the fi lter is in its fi nal position. Keep the sand dry for easy installation. Use only the
approved fi lter sand, otherwise the system may not work satisfactorily.

INSTALLATION LOCATION

LOCATION : System should be installed in accordance with the standards and in­structions in effect in your country or municipality, preferably in a dry, shaded, and
well-ventilated area (See previous warning). Locate the system on a hard, level
surface, preferably in a dry, shaded, and well-ventilated area. Give consideration
to the following: Position of suction, return, and waste connections; Access for
backwashing and servicing; Protection from the sun, rain, splashing, etc; Drainage
of fi lter room or pit; Ventilation and protection of the motor.

ASSEMBLY OF SYSTEM

1). Place the empty tank in position on the base. Press the tank down until it

engages the base.

2). If the laterals are not installed, hold the standpipe/manifold assembly so that
the manifold is located in the middle of the tank. Take one of the lateral fl ow tubes
in your other hand and lower it into the tank, sliding it down the tube and into one
of the grooves in the manifold until a snap-fi t is obtained. Repeat this action until
all eight lateral fl ow tubes are installed, then lower the complete assembly down
to the bottom of the tank. Press it down to ensure that the central tube is seated in
the depression in the base of the tank. See fi gure 1.

PUMP SELECTION

A full line of pool pumps are available for installation with these fi lters. For those
installations where the equipment will be placed above the water level, a
self-priming pump should be selected. Ask your dealer to determine the proper
size and distance from pool or spa and friction losses (restrictions) of associated
equipment. The fi lter system is assembled at the site from a fi lter module and a
pump module. This method allows you to choose a pump providing an optimal
CIRCULATION RATE for a commercial installation (20 U.S. gallons per minute per
square foot of fi ltration surface) or for a residential installation (25 U.S. gallons per
minute per square foot of fi ltration surface or 61 cubic meters per hour per square

meter of fi ltration surface).

15). Install the backwash adapter in the dial valve port marked “waste”.
PLUMBING CONNECTIONS

The provision of gate valves and unions in the pump suction and pool return
lines of a permanent installation will make servicing easier and prevent loss of
water while routine maintenance is in progress. Pump Installation: Follow the
instructions supplied with the pump. Connect the pipes to the fi lter system as
shown on page 3. Do not use pipes smaller than the connections provided.
Support the plumbing so that it puts no strain on either the pump or the fi lter.

FOR SOLVENT WELD CONNECTIONS

Rigid or fl exible PVC pipe can be used. Pipe ends should be clean and free of any
debris caused by the cutting operation. Be sure that the proper adhesive is used
on the type of pipe specifi ed. Recommended Adhesives: These are examples
only and are not intended to restrict brands:

Caution: We recommend that you consider climatic conditions when applying
adhesives. Certain atmospheric situations, such as high moisture content, make
the adhesive action of certain glues less effective. Check the manufacturer’s
instructions.

FOR THREADED CONNECTIONS

Use only Tefl on tape or equivalent on threaded plumbing connections. Other
pipe compounds may damage threads. We do not recommend the use of silicone
or petroleum based compounds. DO NOT OVERTIGHTEN: HAND-TIGHTEN PLUS
1/2 TURN IS SUFFICIENT.

FILTER PLUMBING

If the fi lter is equipped with union connections, union adapters are needed to
complete plumbing connections and may need to be ordered separately.

START-UP PROCEDURE

After completing the preceding items and fi lling the pool with water, put the system
into operation as described below. When the fi lter system is below deck level,
always close the gate valves in the pump suction and pool return lines before you
remove the cover from the hair and lint strainer. Re-open the valves before you
restart the pump.
1a). For in-ground pools: Set the dial valve to WINTERIZE. Remove the cover
from the hair and lint strainer, and fi ll the pump with water. Refi t the cover and
strainer Ring-LokTM - hand tighten only - do not re-tighten strainer Ring-Lok

TM

during operation.
1b). For above-ground pools: When the water level in the pool reaches the skimmer

and return fi tting, the fi lter and pump will begin fi lling with water. Some air may be
trapped in the pump or fi lter, but will be removed when the pump is started.
Removing the pressure gauge temporarily while the fi lter is fi lling with water will
also help remove any trapped air. Replace the pressure gauge when a steady
stream of water appears.

2). Set the dial valve to DRAIN position.

3). Perform pump start-up.

4). After a good fl ow has been established, continue pumping for one minute or

until wastewater is clear, then stop the pump.

5). Set the dial valve to BACKWASH, and start the pump. The pump should deliver
a strong stream of water as soon as it has removed the air from the suction system.
Should the pump fail to prime within two or three minutes, stop the pump and
repeat steps 1 and 2.

6). After a proper fl ow of clean water has been established, operate the fi lter with
the dial valve set to DRAIN, WHIRLPOOL and RINSE for ONE minute each in that
order. Stop the pump before changing valve positions.

7). Set the dial valve back to FILTER. After the fi lter has operated for about 10
minutes, check the pool return fi tting for air bubbles. A continuous fl ow of air
indicates a leak in the suction system, which must be corrected immediately.
