    CHEMICAL BALANCE POOL AND SPA WATER Your Pentair pool heater was designed specifically for your spa or pool and will give you many years of trouble-free service, provided you keep your water chemistry in proper condition. Water chemistry should follow good swimming pool water chemistry practices. When using a chlorinator, install it down stream from the heater and at a lower level than the heater outlet.

  • Page 60: Chemical Balance

    Section 4. Maintenance CHEMICAL BALANCE, (continued) It is wise to test pool water regularly. Never allow chlorine residual to drop below 0.6 ppm (parts per million). The minimum level for effective chlorine or bromine residual is 1.4 ppm. pH - The term pH refers to the acid/alkaline balance of water expressed on a numerical scale from 0 to 14.
