Remove the sand shield from internal diffuser elbow pipe. time to backwash (clean) the filter (see BACKWASH under Filter Control Valve Functions). f. Replace diffuser on internal diffuser elbow pipe, positioning automatic air relief tube through the hole provided in the diffuser. 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. g. Wipe filter flange clean. h. Insert top closure dome (with flange O-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 the pump must be connected to the middle Port B.) Make return to pool pipe connection to control valve opening marked RETURN and (Port E on the Slide Valve) 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. 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 and Open) BACKWASH-For cleaning filter. When filter pressure gauge rises 8-10PSI (0.55-0.69 BAR) above start-up (clean pressure): Stop the pump, set valve to BACKWASH. (Slide Valve 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. 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 Vari-Flo control valve handle and rotate to BACKWASH* position. (To prevent damage to control valve seat, always depress handle before turning.) (For the Slide Valve, the Handle needs to be fully down and LOCKED by rotating 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 - 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 Slide valve to FILTER (Counterclockwise turn and full UP position) or Vari-Flo valve to RINSE position. 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 and restart 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, 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 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 Vari-Flo control valve handle and rotate so as to set pointer on valve top between any two positions. (For Slide Valve leave valve between 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.
