Mechanical Entrapment
There is potential for jewelry, swimsuit, hair decorations, finger, toe or knuckles to be caught in an opening of a suction outlet cover resulting in mechanical entrapment.

WARNING – To Reduce the risk of Entrapment Hazards:

• When outlets are small enough to be blocked by a person, a minimum of two functioning suction outlets per pump must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of three feet (3’) [1 meter] apart, as measured from near point to near point.
• Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
• Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
• The maximum system flow rate shall not exceed the flow rating of as listed on Table 2.
• Never use Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached.
• Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
• In addition two or more suction outlets per pump installed in accordance with latest NSPI, IAF Standards and CPSC guidelines, follow all National, State, and Local codes applicable.
• Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
• WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets can result in an increase potential for suction entrapment as described above.
• WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other material can result in an increase potential for suction entrapment as described above.
• WARNING – Suction outlet components have a finite life, the cover/grate should be inspected frequently and replaced at least every ten years or if found to be damaged, broken, cracked, missing, or not securely attached.
• CAUTION – Components such as the filtration system, pumps and heater must be positioned so as to prevent their being used as means of access to the pool by young children.
• WARNING – Never operate or test the circulation system at more than 40 PSI.
• CAUTION – All electrical wiring MUST be performed by a qualified professional, and MUST conform to local codes and regulations.
• WARNING – Never change the filter control valve position while the pump is running.

WARNING – Hazardous Pressure.
Pool and spa water circulation systems operate under hazardous pressure during start up, normal operation, and after pump shut off. Stand clear of circulation system equipment during pump start up. Failure to follow safety and operation instructions could result in violent separation of the pump housing and cover, and/or filter housing and clamp due to pressure in the system, which could cause property damage, severe personal injury, or death. Before servicing pool and spa water circulation system, all system and pump controls must be in off position and filter manual air relief valve must be in open position. Before starting the system pump, all system valves must be set in a position to allow system water to return back to the pool. Do not change filter control valve position while the system pump is running. Before starting the system pump, fully open the filter manual air relief valve. Do not close filter manual air relief valve until a steady stream of water (not air or air and water) is discharged.

WARNING – Separation Hazard.
Failure to follow safety and operation instructions could result in violent separation of the pump and/or filter components. The strainer cover must be properly secured to the pump housing with the strainer cover lock ring. Before servicing the pool and spa circulation system, the filters’ manual air relief valve must be in the open position. Do not operate pool and spa circulation system if a system component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation system unless filter manual air relief valve body is in the locked position in the filter upper body.

WARNING

• Electrical Ground motor before connecting to the electrical power supply. Failure to ground the pump motor can cause serious or fatal electrical shock hazards.
• WARNING – Do NOT ground to a gas supply line.
• WARNING – To avoid dangerous or fatal electrical shock, turn OFF the power to the motor before working on electrical connections.
• WARNING – Failure to bond pump 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 the pump. Also, contact a licensed electrician for information on local electrical codes for bonding requirements.

Your Hayward Pro Series 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 minimal attention and care.

HOW IT WORKS

Your filter uses special filter sand to remove dirt particles from pool 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 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 back washed (cleaned) of dirt, the control valve is manually resequenced to Rinse, and then Filter, to resume normal filtering.

INSTALLATION

Only simple tools (screwdriver and wrenches), plus pipe sealant 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, on 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 pump and pump mounting base, No. S160TPAK1, or S160TPAK3 (if supplied) to the filter according to instructions packed with the base.

3. Loading sand media. Filter sand media is loaded through the top opening of the filter.

   • Loosen flange clamp and remove Filter Control Valve (if previously installed).

   • Cap the internal pipe with a sand shield to prevent sand from entering it. Be sure pipe is securely in place in the bottom underdrain hub.

   • We recommend filling the tank approximately 1/2 way with water to provide a cushioning effect when the filter sand is poured in. This helps protect the underdrain laterals from excessive shock. (Be sure the winter drain cap is securely in place on the drain pipe).
     NOTE : Check to confirm all laterals are in the down position before loading with sand. (See Figure A.)

   • Carefully pour the incorrect amount and grade of filter sand, as specified on Table 1. (Be sure the center pipe remains centered in the opening). Sand surface should be leveled and should come to within 6″ of the top of the filter tank. Remove the sand shield from the internal pipe.

4. Assemble Filter Control Valve to filter tank.

   • Loosely pre-assemble both halves of the clamp with one screw and one nut, turning the nut 2 or 3 turns. Do not tighten. Wipe filter flange clean.
   • Insert Filter Control Valve (with valve/flange 0-ring in place) into the tank neck, taking care that the center pipe slips into the hole in the bottom of the valve. Install clamp around tank and valve flange and assemble second screw and nut. Tighten just enough so that the valve may be rotated on the tank for final positioning.
   • Wrap two turns of Teflon pipe sealant tape manufactured for the plastic pipe on the ¼” NPT male end of the gauge. Carefully screw pressure gauge, into 1/4″NPT tapped hole in valve body. Do not over-tighten.
   • Connect pump to control valve opening marked PUMP according to instructions. After connections are made, tighten valve flange clamp with a screwdriver, tapping around the clamp with the screwdriver handle to help the seat valve flange clamp.

5. Make a return to pool pipe connection to control valve opening marked RETURN and complete other necessary plumbing connections, suction lines to pump, waste, etc.

6. Make electrical connections to the pump per pump instructions.

7. To prevent water leakage, be sure the winter drain cap is securely in place and all pipe connections are tight.

INITIAL START-UP OF FILTER

1. Be sure the correct amount of filter sand media is in the tank and that all connections have been made and are secure.

2. Depress the Vari-Flo control valve handle and rotate to the BACKWASH* position. (To prevent damage to the control valve seal, always depress the handle before turning.)

3. Prime and start the pump according to pump instructions (be sure all suction and return lines are open), allowing the filter tank to fill with water.
   WARNING: ALL SUCTION AND DISCHARGE VALVES MUST BE OPEN WHEN STARTING THE SYSTEM. FAILURE TO DO SO COULD CAUSE SEVERE PERSONAL INJURY.
   Once water flow is steady out the waste line, run the pump for at least 2 minutes. The initial back-washing of the filter is recommended to remove any impurities or fine sand particles in the sand media.

4. Turn the pump off and set the valve to RINSE position. Start pump and operate until the water in sight glass is clear—about 1/2 to 1 minute. Turn the pump off, set valve to FILTER position and restart the pump. Your filter is now operating in the normal filter mode, filtering particles from the pool water.

5. Adjust pool suction and return valves to achieve the desired flow. Check system and filter for water leaks and tighten connections, bolts, nuts, as required.

6. 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 8-10 PSI (0.55-0.69 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 the 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.

KEEP SAFETY LABELS IN GOOD CONDITION AND REPLACE IF MISSING OR DAMAGED.

IMPORTANT : To prevent unnecessary strain on the piping system and valving, always shut off pump before switching Filter Control Valve positions. 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.

BACKWASH
For cleaning filters. When filter pressure gauge rises 8-10 PSI (0.55-0.69 BAR) above start-up (clean pressure):

Stop the pump, set the valve to BACKWASH. Start pump and backwash until the water in sight glass is clear. Approximately 2 minutes or less depending on dirt accumulation. Proceed to RINSE.

RINSE
After backwashing, with the pump off, set the 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 of the filter to waste, preventing a 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 the water level and for vacuuming heavy debris directly to waste. RECIRCULATE—Water is recirculated through the pool system, bypassing the filter.

CLOSED
Shuts off the flow from the 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 the tank by unscrewing drain cap at base of the filter tank. Leave cap off during winter.
2. Depress the Vari-Flo control valve handle and rotate so as to set the 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 the 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.
