Hayward S200 Series S200 Sand Filter - Page 4

WINTERIZING 1. Completely drain tank by unscrewing drain cap at base of filter tank. Leave cap off during winter. IMPORTANT: If drain pipe starts to turn when unscrewing cap, place wrench on flats on pipe to hold and prevent drain pipe from unscrewing from the filter tank. 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 written 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. PROBLEM SOLVING LIST LOW WATER FLOW SHORT FILTER CYCLES POOL WATER WON'T CLEAR UP REMEDY 1. Check skimmer and pump 1. Check for algae in pool and strainer baskets for debris. superchlorinate as required. 2. Check for restrictions in intake and discharge lines. 3. Check for air leak in intake line (indicated by bubbles returning to pool). 4. Backwash filter. 2. Be sure chlorine and pH levels are in proper range (adjust as required). 3. Check surface of filter sand for crusting or caking (remove 1" of sand if necessary). 1. Check chlorine, pH and total alkalinity levels and adjust as required. 2. Be sure flow rate through filter is sufficient. 3. Operate filter for longer periods. 4. Be sure Vari-Flo valve is set on "Filter" position.
