WARNING – Risk of Electric Shock. All electrical wiring MUST be in conformance with applicable local codes,
regulations, and the National Electric Code (NEC). Hazardous voltage can shock, burn, and cause death or serious property
damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit to electric supply. Provide a properly
located electrical receptacle. Before working on any electrical equipment, turn off power supply to the equipment. To reduce
the risk of electric shock replace damaged wiring immediately. Locate conduit to prevent abuse from lawn mowers, hedge
trimmers and other equipment. Do NOT ground to a gas supply line.
WARNING – Risk of Electric Shock Failure to ground all electrical equipment can cause serious or fatal electrical shock
hazard. Electrical ground all electrical equipment before connecting to electrical power supply.
WARNING – Risk of Electric Shock Failure to bond all electrical equipment to pool structure will increase risk for
electrocution and could result in injury or death. To reduce the risk of electric shock, see installation instructions and consult a
professional electrician on how to bond all electrical equipment. Also, contact a licensed electrician for information on local
electrical codes for bonding requirements.
Notes to electrician: Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug to
reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm2) [No. 6 AWG (13.3 mm2) for Canada] solid copper bonding wire to the
pressure wire connector provided on the electrical equipment and to all metal parts of swimming pool, spa, or hot tub, and metal
piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool, spa, or hot tub.
IMPORTANT - Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding and other general
wiring procedures.
WARNING – Risk of Electric Shock . The electrical equipment must be connected only to a supply circuit that is
protected by a ground-fault circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be tested on a
routine basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push reset button. Power should be
restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to the electrical equipment
without the test button being pushed, a ground current is flowing, indicating the possibility of an electrical shock. Do not use this
electrical equipment. Disconnect the electrical equipment and have the problem corrected by a qualified service representative
before using.
CAUTION – HAYWARD® pumps are intended for use with permanently-installed pools and may be used with hot tubs and
spas if so marked. Do not use with storable pools. A permanently-installed pool is constructed in or on the ground or in a
building such that it cannot be readily disassembled for storage. A storable pool is constructed so that it is capable of being
readily disassembled for storage and reassembled to its original integrity.
WARNING – Risk of Hyperthermia. To avoid hyperthermia the following “Safety Rules for Hot Tubs” are recommended by
the U.S. Consumer Product Safety Commission.
1.
Spa or hot tub water temperatures should never exceed 104°F [40°C]. A temperature of 100°F [38°C] is
considered safe for a healthy adult. Special caution is suggested for young children. Prolonged immersion in
hot water can induce hyperthermia.
2.
could lead to unconsciousness and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 100°F [38°C] can cause fetal damage during the
Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness, which
first three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women
should adhere to the 100°F [38°C] maximum rule.
4.
mometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).
5. Persons taking medications, which induce drowsiness, such as tranquilizers, antihistamines or anti-
coagulants, should not use spas or hot tubs.
6. If the pool/spa is used for therapy, it should be done with the advice of a physician. Always stir pool/ spa
Before entering the spa or hot tub, users should check the water temperature with an accurate ther-
water before entering the pool/spa to mix in any hot surface layer of water that might exceed healthful
temperature limits and cause injury. Do not tamper with controls, because scalding can result if safety controls
are not in proper working order.
7.
problems should obtain a physician’s advice before using spas or hot tubs.
8. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above
Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure
normal body temperature of 98.6°F [37°C]. The symptoms of Hyperthermia include: drowsiness, lethargy,
dizziness, fainting, and an increase in the internal temperature of the body.
The effects of Hyperthermia include:
1. Unawareness of impending danger.
2. Failure to perceive heat.
3. Failure to recognize the need to leave the spa.
4. Physical inability to exit the spa.
5. Fetal damage in pregnant women.

Your Hayward ProSeries™ high-rate sand filter is a high performance, totally corrosion-proof filter that blends superior
flow characteristics and features with ease of operation. It represents the very latest in high-rate sand filter technology. It
is virtually foolproof in design and operation and when installed, operated and maintained according to instructions, your
filter will produce clear, sparkling water with only the least attention and care.
HOW IT WORKS
Your filter uses special filter sand to remove dirt particles from the water. Filter sand is loaded into the filter tank and
functions as the permanent dirt removing media. The pool water, which contains suspended dirt particles, is pumped
through your piping system and is automatically directed by the patented filter control valve to the top of the filter tank. As
the pool water is pumped through the filter sand, dirt particles are trapped by the sand bed, and filtered out. The cleaned
pool water is returned from the bottom of the filter tank, through the control valve and back to the pool through the piping
system. This entire sequence is continuous and automatic and provides for total recirculation of pool water through your
filter and piping system.
After a period of time, the accumulated dirt in the filter causes a resistance to flow, and the flow diminishes. This means it
is time to clean (backwash) your filter. With the control valve in the Backwash position, the water flow is automatically
reversed through the filter so that it is directed to the bottom of the tank, up through the sand, flushing the previously
trapped dirt and debris out the waste line. Once the filter is backwashed (cleaned) of dirt, the control valve is manually
sequenced to Rinse, and then Filter, to resume normal filtering.
INSTALLATION
Only simple tools (screwdriver and wrenches), plus Teflon tape manufactured for plastic adapters, are required to
install and/or service the filter.
1. The filter system should be installed, not more than 6 feet above pool water level, on a level concrete slab, very
firm ground, or equivalent, as recommended by your pool dealer. Position the filter so that the piping
connections, control valve, and winter drain are convenient and accessible for operation, service and winterizing.
2. Assemble a filter control valve to filter. Align the two (2) valve pipe connections, with 0-rings in place, with the two
openings in the side of the filter tank and press in firmly. Secure the assembly to the tank connections with the
two bulkhead locknuts. Do not overtighten.
3. Assemble pump and pump mounting base (if supplied) to the filter according to instructions packed with the base.
4. Loading sand media. Filter sand media is loaded through the top opening of the filter.
a. Remove the top diffuser from the internal diffuser elbow pipe and place flexible, automatic air relief tube to the side,
out of the way, inside the tank.
b. Cap the internal diffuser elbow pipe with the sand shield
provided to prevent sand from entering it.
c. It is good practice to fill tank approximately 1/2 way with water to
provide a cushioning effect when the filter sand is poured in.
This helps protect the under-drain laterals from excessive shock.
(Be sure the drain cap is securely in place on drain pipe.)
Note: Check to confirm all laterals are in the down position before
loading with sand. (See Figure A on Page 6.)
d. Carefully pour in correct amount and grade of filter sand, as
specified. Sand surface should be leveled and should come to
about 6“ from the top of the filter tank. Use no more than the
recommended amount of sand.
e. Remove the sand shield from internal diffuser elbow pipe.
f. Replace diffuser on internal diffuser elbow pipe, positioning
automatic air relief tube through the hole provided in the
diffuser.
g. Wipe filter flange clean.
h. Insert top closure dome (with flange 0-ring in place) into the tank
neck. Place clamp around dome flange and tank flange and
tighten with screwdriver, tapping around clamp with screwdriver
handle to help seat flange clamp.
Do not overtighten.
5. Connect pump to control valve opening marked PUMP according to
instructions. (For Slide valve use PORT B, middle port.) Make return
to pool pipe connection to control valve opening marked RETURN
(Port E bottom Port for Slide Valve) and complete other necessary
plumbing connections, suction lines to pump, waste, etc.
6. Make electrical connections to pump per pump instructions.
7. To prevent water leakage, be sure drain cap is securely in place and
all pipe connections are tight.

INITIAL START-UP OF FILTER
1. Be sure correct amount of filter sand media is in tank and that all connections have been made and are secure.
IMPORTANT: To prevent unnecessary strain on piping system and valving, always shut off pump before switching
Filter Control Valve positions.
2. Depress VariFlo® control valve handle and rotate to BACKWASH* position. (To prevent damage to control valve seat,
always depress handle before turning.) For Slide Valve, set handle to BACKWASH* position. (Handle full down and
LOCKED by twisting clockwise.)
3. Prime and start pump according to pump instructions. (Be sure all suction and return lines are open), allowing the filter
tank to fill with water.
WARNING – Separation Hazard -All suction and discharge valves must be open when starting the
system. Failure to do so could cause severe personal injury and/or property damage.
4. Once water flow is steady out the waste line, run the pump for at least 2 minutes. This initial backwashing of the filter is
recommended to remove any impurities or fine sand particles in the sand media.
5. Turn pump off and set VariFlo valve to RINSE position (Not available on slide valve.). Start pump and operate until water in
sight glass is clear—about 1/2 to 1 minute. Turn pump off, set valve to FILTER position (For Slide Valve twist Handle fully
counterclockwise to open and pull up fully. ) Start the pump. Your filter is now operating in the normal filter mode,
filtering particles from the pool water.
6. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water leaks and tighten
connections, bolts, and nuts as required.
7. Note the initial pressure gauge reading when the filter is clean. (It will vary from pool to pool depending upon the pump
and general piping system.) As the filter removes dirt and impurities from the pool water, the accumulation in the filter
will cause the pressure to rise and flow to diminish. When the pressure gauge reading is 6-8 PSI (0.41-0.55 BAR) higher
than the initial "clean" pressure you noted, it is time to backwash (clean) the filter (see BACKWASH under Filter Control
Valve Functions).
NOTE: During initial clean-up of the pool water it may be necessary to backwash frequently due to the
unusually heavy initial dirt load in the water.
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets
regularly.
FILTER CONTROL VALVE FUNCTIONS
FILTER—Set valve to FILTER for normal filtering. Also use for regular vacuuming. (Slide Valve handle up)
BACKWASH—For cleaning filter. When filter pressure gauge rises 6-8 PSI (0.41-0.55 BAR) above start-up (clean pressure):
Stop the pump, set valve to BACKWASH. (Slide Valve handle down and locked.)Start pump and backwash
approximately 2 minutes or less depending on dirt accumulation until water in sight glass is clear. Proceed to
RINSE.
RINSE—After backwashing, with pump off, set valve to RINSE. Start pump and operate for about 1/2 to 1 minute. This ensures
that all dirty water from backwashing is rinsed out to the filter to waste, preventing possible return to the pool. Stop
pump, set valve to FILTER, and start pump for normal filtering.
WASTE—To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to waste.
RECIRCULATE—Water is recirculated through the pool system, bypassing the filter.
CLOSED—Shuts off flow from pump to filter.
VACUUMING—Vacuuming can be performed directly into the filter. When vacuuming heavy debris loads, set valve to WASTE
position to bypass the filter and vacuum directly out to waste.
WINTERIZING
1. Completely drain tank by unscrewing drain cap at base of filter tank. Leave cap off during winter.
2. Depress VariFlo control valve handle and rotate so as to set pointer on valve top between any two positions. This will allow
water to drain from the valve. Leave valve in this "inactive" position.
3. Drain and winterize pump according to pump instructions.
SERVICE & REPAIRS
Consult your local authorized Hayward dealer or service center. No returns may be made directly to the factory without the
expressed authorization of Hayward Pool Products, Inc.
PLEASE REALIZE:
Pure, clear swimming pool water is a combination of two factors—adequate filtration and proper water chemistry balance. One
without the other will not give the clean water you desire.
Your filter system is designed for continuous operation. However, this is not necessary for most swimming pools. You can
determine your filter operation schedule based on your pool size and usage. Be sure to operate your filtration system long
enough each day to obtain at least one complete turnover of your pool water.
To properly sanitize your pool, maintain a free chlorine level of 1 to 3 ppm and a pH range of 7.2 to 7.6. Insufficient chlorine or
an out of balance pH level will permit algae and bacteria to grow in your pool and make it difficult for your filter to properly
clean the pool water.
*NOTE: For new concrete or gunite pools, or where there is a large amount of plaster dust or debris—start filter in FILTER position (not BACKWASH) to prevent clogging of
underdrain laterals.
