Page 4 of 8 MODEL S144T, S164T IS144T Rev B 1 ½ turns past hand tight to avoid failure due to over tightening the joint. g. Place two hose clamps (17) over clear hose (15). Fit hose over straight and elbow adapters and secure with the clamps. (HINT: If it is difficult to fit hose over adapters, place hose in hot water for several minutes. Be Careful HOT WATER can burn you). After the hose connections are made, tighten valve flange clamp with screwdriver, tapping around clamp with screwdriver handle to help seat valve flange clamp. Please be sure to place the vinyl protector caps over the ends of the screws. 5. Make 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 pump per pump instructions. 7. To prevent water leakage, be sure winter 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. 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. Start pump and backwash until water in sight glass is clear. Approximately 2 minutes or less depending on dirt accumulation. Proceed to FILTER. 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. 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. 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. 2. Depress Vari-Flo control valve handle and rotate to BACKWASH* position. (To prevent damage to control valve seal, always depress handle before turning.) 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. 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. 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. 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 pump off and set valve to FILTER position. 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 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 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. KEEP SAFETY LABELS IN GOOD CONDITION AND REPLACE IF MISSING OR DAMAGED. IMPORTANT: To prevent unnecessary strain on piping system and valving, always shut off pump before switching Filter Control Valve positions. 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.
