HAYWARD S360SX (02) PDF Document

Your HAYWARD S360SX filter uses special filter sand to remove dirt particles from the pool water. The filter sand is loaded into the filter tank and acts as the permanent dirt-removing media. The pool water, containing suspended dirt particles, is pumped through your piping system and is automatically directed by the 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 returns 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, providing 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. 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.

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 the pool water level, on a level concrete slab, very firm ground, or equivalent. 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 o-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 the 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 the 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 the 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 the drain pipe.)

Note: Check to confirm all laterals are in the down position before loading with sand.

d. Carefully pour in the correct amount and grade of filter sand, as specified. The 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 the internal diffuser elbow pipe.

f. Replace the diffuser on the internal diffuser elbow pipe, positioning the automatic air relief tube through the hole provided in the diffuser.

g. Wipe the filter flange clean.

h. Insert the top closure dome (with flange o-ring in place) into the tank neck. Place the clamp around the dome flange and tank flange and tighten with a screwdriver, tapping around the clamp with the screwdriver handle to help seat the flange clamp. Do not overtighten.

5. Connect the pump to the control valve opening marked PUMP according to instructions. (For Slide valve use PORT B, middle port.) Make the return to pool pipe connection to the control valve opening marked RETURN (Port E bottom Port for Slide Valve) and complete other necessary plumbing connections, suction lines to the pump, waste, etc.

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

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

1. Be sure the correct amount of filter sand media is in the tank and that all connections have been made and are secure. IMPORTANT: To prevent unnecessary strain on the piping system and valving, always shut off the pump before switching Filter Control Valve positions.

2. Depress the VariFlo® control valve handle and rotate to the BACKWASH* position. (To prevent damage to the control valve seat, always depress the handle before turning.) For the Slide Valve, set the handle to the BACKWASH* position. (Handle full down and LOCKED by twisting clockwise.)

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.

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 the pump off and set the VariFlo valve to the RINSE position (Not available on the slide valve.). Start the pump and operate until the water in the sight glass is clear – about 1/2 to 1 minute. Turn the pump off, set the valve to the FILTER position (For the Slide Valve twist the 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 the desired flow. Check the 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.

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.

*NOTE: For new concrete or gunite pools, or where there is a large amount of plaster dust or debris, start the filter in the FILTER position (not BACKWASH) to prevent clogging of underdrain laterals.

FILTER – Set valve to FILTER for normal filtering. Also use for regular vacuuming. (Slide Valve handle up)

BACKWASH – For cleaning the filter. When the filter pressure gauge rises 6-8 PSI (0.41-0.55 BAR) above start-up (clean pressure): Stop the pump, set the valve to BACKWASH. (Slide Valve handle down and locked.) Start the pump and backwash for approximately 2 minutes or less depending on dirt accumulation, until water in the sight glass is clear. Proceed to RINSE.

RINSE – After backwashing, with the pump off, set the valve to RINSE. Start the 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 possible return to the pool. Stop the pump, set the valve to FILTER, and start the pump for normal filtering.

WASTE – To bypass the 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 flow from the pump to the filter.

VACUUMING – Vacuuming can be performed directly into the filter. When vacuuming heavy debris loads, set the valve to the WASTE position to bypass the filter and vacuum directly out to waste.

1. Completely drain the tank by unscrewing the drain cap at the base of the filter tank. Leave the cap off during winter.

2. Depress the VariFlo control valve handle and rotate so as to set the pointer on the valve top between any two positions. This will allow water to drain from the valve. Leave the valve in this “inactive” position.

3. Drain and winterize the pump according to pump instructions.

**Also known as No. 20 Silica Pool Sand

LOW WATER FLOW

• Check skimmer and pump strainer baskets for debris.

• Check for restrictions in intake and discharge lines.

• Check for air leak in intake line (indicated by bubbles returning to pool).

• Backwash filter.

SHORT FILTER CYCLES

• Check for algae in pool and superchlorinate as required.

• Be sure chlorine and pH levels are in proper range (adjust as required).

• Check surface of filter sand for crusting or caking (remove 1″ of sand if necessary).

POOL WATER WON’T CLEAR UP

• Check chlorine, pH and total alkalinity levels and adjust as required.

• Be sure flow rate through filter is sufficient.

• Operate filter for longer periods.

• Be sure Vari-Flo valve is set on “Filter” position.
