Jandy Winterizing Cap for Pro Series TruClear Chlorine Generating System

The Jandy R0621900 is the winterizing cap for the Pro Series TruClear chlorine generating system. At closing time it seals the salt cell off from the rest of the plumbing, so water cannot sit in or flow into the cell while the pool is shut down for the winter.

Simple to use

The cap goes on by hand at closing and comes off at opening, with no tools. It is small and light, so it stores easily during the swim season, and its corrosion resistant construction means it lasts through many winters of salt water exposure.

Part of a complete winterization

If you are closing a TruClear system, it is a good time to inspect the cell o-ring and housing as well. Both are available as separate Jandy parts.
