The R171016 Pentair Rainbow 300 Automatic Off-Line Chlorinator Feeder uses 1-inch or 3-inch trichlor tablets. The frequency of refilling the feeder depends on the size of the chlorinator, the amount of water being treated, and the usage of the pool or spa. Typically, the feeder needs to be refilled every few weeks to a few months.

To adjust the chlorine feed rate on the R171016 Pentair Rainbow 300, first turn off the pool or spa pump. Then, loosen the adjustment ring and move it up or down to increase or decrease the amount of chlorine being dispensed. Finally, tighten the adjustment ring and restart the pump to allow the feeder to distribute the adjusted amount of chlorine. It is important to regularly check and adjust the feed rate to maintain optimal water chemistry.
