How do I remove (and replace) my Flexjets?

Beachcomber's FlexJet system lets you mix and match massage inserts giving you control over the therapy you desire. They are easy to remove and replace. Take hold of the outer FlexJet ring and twist counter clockwise. You will feel resistance. Keep turning until the jet pops out or unscrews. It's a lot like twisting out a light bulb. Then twist back in another FlexJet of the same size. Each FlexJet has from one to seven different jets within the FlexJet 'massage insert', allowing you to create the number of jet streams you desire.
