4. Turn pump off and set 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. 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 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 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. 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 8-10 PSI (0.55-0.69 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 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 of the filter to waste, preventing 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 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. 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 MAXIMUM RECOMMENDED SYSTEM FLOW RATE BY PIPE SIZE Pipe Flow rate Pipe Flow rate Pipe Flow rate Size GPM Size GPM Size GPM [mm] [Liter/Min] [mm] [Liter/Min] [mm] [Liter/Min] 1" 20 1 ½" 45 2 ½" 110 [32] [75] [50] [170] [75] [415] 1 ¼" 30 [40] [110] 2" 80 [63] [300] 3" 160 [90] [600] TABLE 1 SUGGESTED POOL CHEMISTRY pH 7.2 to 7.6 TOTAL ALKALINITY 80 to 120 ppm CALCIUM HARDNESS 200 to 400 ppm COMBINED CHLORINE 0.2 ppm Maximum CHLORINE (STABILIZED) 1.0 to 3.0 ppm CHLORINE STABILIZER (Cyanuric Acid) 60 to 80 ppm USE ONLY HAYWARD GENUINE REPLACEMENT PARTS USE ONLY HAYWARD GENUINE REPLACEMENT PARTS 5 5
