Rainbow filter lid with tablet dispenser

The Pentair Rainbow filter lid has an integrated chemical diffuser that you use with slow-dissolving 1-inch bromine or chlorine tablets. This lid is pre-installed in the RCF Dynamic III filter, and can be retrofitted to the RTL Dynamic II, where it replaces the standard lid.

The non-calibrated dial at the top of the dispenser determines the rate of flow over the tablets, and can be used to adjust the rate at which they dissolve.

The manufacturers instruction sheet is included.
