Once you have installed your spa, your next step is to fill it up with water for heating. We recommend that you use a garden hose placed inside the filter housing to fill the water up with cold water instead of hot water, as this could cause the temperature sensors to malfunction. On our newer models, the tub should be filled up to the bottom of the headrests, and on some older models there should be a water line gauge on the skimmer basket.
