Inflate the floor first, then one of the side tubes, then the second one to 50%. Check the overall chamber positioning. Then inflate to 100% without exceeding 0.1 bar (1.5 psi).
DO NOT OVERINFLATE!
Fully close all of the valves.
Install the 3 keels, unless using on a river containing little water.
In the event of EXTREME HEAT, slightly deflate the kayak out of the water to avoid overinflation, which could damage the kayak.
Do not leave inflated in direct sunlight: risk of overinflation.
