Inflate the floor, then one of the tubes, then the second one to 50%. Check the overall positioning of the chambers. Then fully inflate it without exceeding 0.1 bar (1.5 psi).
DO NOT OVERINFLATE!
Ensure the valves are securely closed.
Install the 3 skegs, unless using on a river containing little water.
In the event of EXTREME HEAT, slightly deflate out of the water to avoid overinflation, which could damage the kayak.
Do not leave inflated in direct sunlight: risk of overinflation.
