TM83.2 Understanding Your ValvesAdvanced Elements Lagoon2™ kayak uses the following valves. The Advanced Elements springvalve has the function and durability of other military type valves and is compatible with moststandard pumps. The lock nut holds the valve in place with the cover for easy inflation. Thefollowing figures will have details on how to operate the valves.To Inflate: The valve’s plunger stem should be in the up/outward position flush with the valvethreading.To Deflate: The valve’s plunger stem should be set in the down/inward position recessed in thevalve threading.In order to switch the valve from inflate to deflate or vice-versa, simply use your finger topress the valve stem down/inward and rotate it a 1/4 turn to either lock it down for deflate, orunlock it (stem will spring up) for inflate.How the Spring Valve Works:When the valve is in the inflate (up/outward) position, the air being pumped in pushes thespring-loaded plunger open, allowing air to enter the air chamber, but not letting it escape.When the valve is in the deflate (down/inward) position, the spring loaded plunger is wide openallowing the air to come rushing out of the air chamber. If the valve is in the inflate position, thevalve’s plunger stem will be flush with the rim of the valve. If the valve is in the deflate position,the valve’s plunger stem will be inside, or lower than, the rim of the valve. To change the valvefrom the inflate position to the deflate position, simply use your finger to press the valve plungerstem down/inward, and give it a 1/4 turn. This will lock the plunger open and allow the air torush out. Use the same procedure in reverse to unlock the valve plunger, allowing it to spring upinto the inflate position.Special Note: If you are using a 12v inflator, like those that come with most inflatable mattressesor those that plug into car cigarette lighters, you may need to have the valve in the deflate (down/inward) position because these types of pumps typically do not provide enough air pressureto press the plunger open to allow air into the air chamber. Additionally, 12v inflators do notprovide enough pressure to fully inflate the kayak, so you will need a secondary pump to finishthe job.Using the NEW “Screw-on” Spring Valve Adaptor:The screw-on Spring Valve Adaptor was designed to enable the pump hose to securely connect tothe Advanced Elements Spring Valve without falling off during inflation, making inflation easier.The valve adaptor also has a semi-circle protrusion that depresses the valve stem, opening thevalve slightly to allow pumps with pressure gauges to take a constant reading. When inflatingthe kayak using the Spring Valve Adaptor, the valve should be in the inflate position.
