Page 3 of 8 MODEL S311SX,S311SXV,S360SX IS311SX Rev B WARNING - Electrical Ground motor before connecting to electrical power supply. Failure to ground pump motor can cause serious or fatal electrical shock hazard. WARNING - Do NOT ground to a gas supply line. WARNING - To avoid dangerous or fatal electrical shock, turn OFF power to 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 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 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 resequenced 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 the 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. 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 5.) 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. WWW.HAYWARDPOOL.COM USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
