Start up — Set the provided 7-day timer* to come on 45 minutes prior to spa opening and set to shut off automatically at spa closing time. Upgrade — The low energy use of the warmer allows for all day use. With the warmer on and ready, guests can easily upgrade classic treatments with Himalayan salt. Clean up — Caring for your stones with Decon 3, an EPA-registered, hospital-grade disinfectant, is an extra preventative step. Nontoxic, Decon 3 will not harm the guest, therapist, or salt stones. Simply spray and wipe dry between treatments.
