HOW TO USE THE ERS DUAL ACTION SUP PUMP

THE MANUAL INFLATION PROCESS


A properly inflated board is essential for getting the best out of your session – It’s important to adhere to a routine of correct technique and proper practice every time you inflate or deflate your board. Whilst these tips are intended for Earth River SUP inflatables we have generalised this guide so it can be applied to most inflatable SUPs. In not using an Earth River SUP always consult the specifics of your particular board to prevent potential damage.

INFLATION


ERS boards are equipped with a high quality spring-loaded military inflation valve at the nose or tail of the board. To inflate, first remove the protective valve cover by twisting it counter clockwise.  This will expose the valve stem at the center of the valve assembly. To get familiar with valve operation, push down on the valve stem, turn it clockwise 1/4 turn, and release it.  This will toggle it between the open and closed position. See below to identify the open and closed positions.  ALL INFLATION is done with the valve stem in the CLOSED (UP) position and DEFLATION is done in the OPEN (DOWN) position

VALVE TO OPEN POSITION

This is the correct position for INFLATION as the pump hose will depress the valve enough to allow airflow and it will close instantly to retain air pressure when removed.

CONNECT LOWER CHAMBER

Tighten the hose connector until secure, but be careful not to over tighten. The gauge will initially read “0” and will start displaying an accurate reading (within 1PSI) after a minimum amount of pressure is built up in the board.

PUSH DOWN SLIGHTLY

Push down slightly. The hose pushes the spring on the closed valve to allow it to open for pumping and creates an airtight seal.

QUARTER TURN HOSE

A quarter turn engages the pump lock mechanism that keeps the valve open allowing inflation.

PLACE STOP IN

This is the fastest way to pump, but the upstroke will start to get difficult at around 10PSI. When the upstroke becomes difficult remove the stopper to switch to single action mode.

REMOVE STOP ABOUT 10PSI

The single action mode is best after reaching pressures above 10PSI. Simply remove the stopper, and the pump will only pump on the downstroke, allowing a much easier return to the starting pumping position.

REPLACE VALVE CAP

Insert the valve cover to protect the valve / stem and to prevent accidental deflation.

 
 

DEFLATION


The procedure for deflating your board is similar to the inflation procedure with a few differences. The board valve should be set in the OPEN position which will drain 90% of the air from the board before connecting the pump. The pump should then be used to drain the remaining air from the board before correctly rolling for transport or storage

RELEASE AIR AND CONNECT HOSE

To begin, push the stem with your thumb to the DOWN (OPEN) position and rotate 1/4 turn to release most of the air. Connect the hose in the same manner as you inflated the board.

CONNECT UPPER CHAMBER

Make sure the board valve is in the OPEN position when deflating. Use the pump to remove the remaining air to make the board easier to fold and store.

REMOVE STOP

Fore removing remaining air it is much easier to remove the stop and just use the pump downstroke.

REPLACE VALVE COVER

Remove the pump hose and replace the valve cover to protect the valve stem.

IMPORTANT SAFETY INFORMATION


Proper manual pumping technique uses the entire body.  Initially, it will be easiest to pump using mainly your arms.  As the pressure increases, you’ll want to bend and extend your legs with each stroke to make use of your body weight and core muscles. Manual pumping can be tiring, so take regular breaks when needed. After inflation to 15 PSI, carefully disconnect the hose from the valve by grasping the hose end firmly and rotating it counterclockwise until the air pressure ejects it from the valve.  The cap helps prevent air loss or accidental deflation and also protects the valve from debris.

CAUTION:  When removing the hose from the board valve, grasp the hose end FIRMLY to prevent high velocity recoil of the hose, which can cause serious injury.

MAXIMUM AIR PRESSURE: The correct pressure for and ERS board is 15 PSI. The pressure inside the board’s air champber increases with higher temperatures, so the PSI may rise above the starting pressure during use or transport. Likewise, the pressure inside the board may decline in colder weather. If the board becomes overinflated due to increasing ambient temperature or inflation error, push down on the valve stem to deflate until you reach the recommended pressure. If the board is underinflated, re-attach the pump and inflate until the desired PSI reading is attained.
