Hayward Pro-Series™ Top Mount Systems Model: S310T - Page 4

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. PROBLEM SOLVING LIST REMEDY LOW WATER FLOW 1. Check skimmer and pump strainer baskets for debris. 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. SHORT FILTER CYCLES 1. Check for algae in pool and superchlorinate as required. 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). POOL WATER WON'T CLEAR UP 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. POOL CHEMISTRY GUIDELINES SUGGESTED POOL CHEMISTRY LEVELS pH 7.2 to 7.6 ACTION REQUIRED TO CORRECT POOL CHEMISTRY TO RAISE TO LOWER Add Soda Ash Add Muriatic Acid or Sodium Bisulphate TOTAL ALKALINITY 100 to 130 ppm Add Sodium Bicarbonate Add Muriatic Acid CHLORINE (UNSTABILIZED) 0.3 to 1.0 ppm Add Chlorine Chemical No action - chlorine will naturally dissipate CHLORINE (STABILIZED) 1.0 to 3.0 ppm Add Chlorine Chemical No action - chlorine will naturally dissipate CHLORINE STABILIZER (Cyanuric Acid) 40 to 70 ppm Add Stabilizer Dilution - partially drain & refill pool with water that has not been treated with Cyanuric Acid.
