Re: MK2 GR inflation instructions

These valves each connect two chambers, one rear chamber and the front chamber. So if both valves are set so the chambers are connected then you can inflate the whole boat from one valve.
To inflate, the valve must be in the inflate zone (notice the little arrow on the valve and the writing on the fabric tab under the valve)
Take a look inside the valve with a flashlight, with both caps off. Turn the valve while you look, you will see when the two holes in the inner valve body line up with the two holes in the outer valve body. That is the spot where the valve is communicating with both chambers. Set both valves to this spot and then cap off one side and inflate the boat from the other valve. I use a shop vac to get the boat mostly inflated then top off with the foot pump.
Make sure you turn both valves to the navigate zone when finished inflating so if one chamber gets a puncture the other chambers remain inflated.
