How do you empty the hot tub when it comes time to change or empty the water?

J.C.
With the power pack running. Put one end of a garden hose where you want the water draining to (for example, a floor drain or onto the ground). Hold the other end of the hose in front of the discharge jet on your AiriSpa. (The discharge jet is located on the same side as the power pack. It is inside the tub down near the floor of the spa.) Hold the garden hose so that water goes into it, and then begins flowing out the other end where you are draining. Then then lay the hose on the floor of the spa. It will siphon itself out. Finally, unplug the power pack.
