ASSEMBLY INSTRUCTIONS / INFLATION
If the board was stored at a temperature below 0°C / 32°F, leave it at room temperature for 6 hours before
unfolding. Only then inflate it with the pump provided to a pressure between 16 PSI and 20 PSI maximum.
We recommend 18-20 PSI for optimal performance. Choose a smooth and clean surface to unfold your
product.
Your product is equipped with a removable High-pressure valve. To inflate, open the cap by turning it
counter clockwise. Check and make sure the spring-loaded pin is not depressed and locked in the up
position. To verify that the valve is not open, push the pin down and turn it clock wise. If the pin stays
down, you have now opened that valve. To close it, turn the pin counter clockwise so it springs back up.
Now the valve is closed. All inflation is done in the LOCKED UP position and deflation is done in the OPEN
DOWN position. To attach the pump hose to the high pressure valve, use the appropriate nozzles and
fittings which are supplied with the high pressure pump (the red rubber ring is the correct one for our
boards). Push the fitting into the valve and turn clock wise to lock it. Inflate until you will reach the required
pressure. After inflation disconnect the hose from the valve and close the valve with the cap. Please note: It
is very rare but should the whole valve assembly become loose, the board will leak from around the
outside of the valve. The spanner provided can be used to retighten the valve but only with the board
deflated before tightening. The website or Sandbanks Style personnel will be happy to advise on how
best to do this.
Max air pressure: The correct pressure for this item is; 20PSI Do not exceed it. The board will perform
best when inflated to at least 18PSI. The board is tested up to 29 PSI but it gets no stiffer after 20PSI
so there is no benefit going higher. The manual pump supplied will not damage the board so have
confidence to pump hard.
When you first inflate the board you may have the impression that the board is already stiff before the
pressure gauge even starts to register. Just have confidence and keep on pumping. Initially set the
pump to double action for the most rapid inflation, but it will become hard to pump upwards by about 4
PSI and then set it to single (down stroke only) for the remainder of the inflation. See the Sandbanks
Style website for more details on how to make pumping easier. Varying the muscles used throughout
pumping is the key to this. Try standing over the pump with arms locked and drop your weight over the
pump by bending your legs. In the case of Over-pressure: deflate until you reach the recommended
pressure by gently pressing on the valve stem, note that air will rush out fast with a loud sound. If
pressure is too low: inflate again to desired level.
WARNING!
If you leave your iSUP exposed to the hot sun check the pressure and deflate it
slightly, otherwise the material might be overstretched. Always remove some air if
you are going to leave your board exposed in hot sunshine. Our boards have a lot of
safety margin but Catastrophic damage can result from over pressure bursting the
board. This is not covered by warranty.
The ambient temperature affects the tube’s internal pressure: a variation of 10°C
causes a variation of the pressure in the tube by about 0.4bar or 6PSI
When you first start inflating it’s best to have the leaver at the back of the
pump turned to the right. In this setting the pump will work on double
action, pumping on both the up and the down stroke. When this gets too
difficult twist the leaver to the left and the pump will swap to single
action. In this setting the pump will only act on the down stroke which will
make it much easier for you and your arms.
Tip: At higher pressure it’s best to do shorter strokes while keeping your
arms locked and bending your legs to let your body weight do the work.
