Some Dimension One Spas originally had only a filter cover over the thinner filter. A Safety By-Pass Ring was later added. You’ll need to add the By-Pass Ring in order to replace an old Filter Cover. If you have any questions about this installation please call us Toll-Free (866)-418-1840.
This is what a completed Safety By-Pass Assembly looks like.
Apply a bead of silicone to the base of the Safety By-Pass Ring.
Turn the ring over and lay over the filter opening. Let silicone cure for 24 hours.
Snap the filter cover onto the ring.
