INFLATION

1.  Your HS ISUP is equipped with an HI-794C high pressure valve. Unscrew the cap and check if the valve is closed by pushing the spring-

loaded stem down and turning it. If the stem stays down, the valve is open, and air will escape after pumping. To close it, push the stem 
down and turn it counterclockwise until it springs up. It is now a one way air valve, and air can be pumped into the valve but can not 
escape out of the valve.

2.  Attach your pump hose to the valve by turning the nozzle clockwise to lock it in place. 
3.  Inflate to 

15 PSI

. The manual pump will not register until 7-8 PSI.  

Keep pumping

 if the gauge has not registered. Only use HS branded or 

approved electric pumps with an automatic shutoff to avoid over inflation.

4.  After inflation, disconnect the hose from the valve by pressing it down and turning counterclockwise. Close the valve with the cap. 
 
*When inflated, there may be a small bump on the bottom of the board, directly underneath the valve. This is normal and will not effect its 
performance. This space is necessary during manufacturing to insert and connect the valve to the board.
*

Never transport the HS ISUP fully inflated. 

Damages or warping incurred by improper transport are not covered by the manufacturer’s 

warranty.
*

Do not leave your HS ISUP in direct sunlight when out of the water. 

Find a shaded area for it. Prolonged sun exposure can damage the 

board and void the warranty. 

DEFLATION

1.  Make sure that the valve area is dry.
2.  Unscrew the valve cap and push the valve stem down lightly. Air will rush out quickly at first, then slowly release.
3.  Once air release slows, push the valve stem down and turn it clockwise to keep the valve in the open position.
4.  Roll up the board from the opposite end of the valve so remaining air can escape. Once all the air has been released, push the valve 

stem up to close the valve and then close the cap. 

5.  The side fins should be facing out to maintain their shape. 

*The wrench included in the repair kit should only be used to tighten leaking valves, which happens rarely. 

Never

 use it to deflate your board. 

FINS

1.  With the fin box lever pointed up, insert the knobbed side of the fin into the front of the box and then press down on the back of the fin. 
2.  Apply pressure until the fin is flush with the fin box.
3.  Push the lever down so that it touches the board. It is now locked in. To release the fin, flip the lever up and remove the fin from the box.

CLEANING/STORAGE

1.  Clean your HS ISUP and accessories thoroughly after each use, rinsing off any sand or saltwater residue. Use a mild soapy solution for 

cleaning.  

2.  Make sure the board is completely dry before storing it.
3.  When storing your board, keep it in a cool and dry place that is not susceptible to major temperature variations and other damaging 

factors. You may store it deflated and rolled up in the storage bag (recommended), or partially inflated.
