  • Additional Info


    Should NOT leave the pump working on the dusty ground during your operation. Since the pump's working vibration will bring up the dusty air from the bottom, When much dust going into the air pump, the dust will make the pump's piston grease dry out faster than normal. Then the pump piston ring will overheat and be damaged, and your pump may not be able to provide good high pressure very shortly. Dust Damage will have no warranty coverage. Please keep it working inside your car or on top of your SUP better. We have provided ultra-long wire and hose for your convenience. 

    Most Trouble Shooting - About Pump Stop Working

    Our Seamax pump has a temperature sensor built-in, the pump will stop when it getting overheated. When the pump is forced to stop on overheat, you may not be able to operate it right the way, The LED screen will show you the Error Message. and you can feel the pump is hot. The pump can be operated again when the internal average temperate drops below 80°C / 176°F. So you get to wait for its cold down. or you can try disconnecting it from the SUP, press the ON button to run the pump in the air, its 1st stage fast airflow will help its cool down faster. you may want to run it for 1 minute, and cool it down for 5 minutes before the next use.

    About the overheat, the input voltage will be the first thing to check, Pump allowed working range is 9-15V. The screen voltage reading will show you the real-time voltage when pumping. this is very important to know during your pumping. And over this voltage range, the pump won't be started, and the Error message will be showing on the screen as well if you pressing the ON button.

    If the voltage is too low (below 10V), the motor can not get enough power to push the air, so the airflow will be very slow. the heat from the motor and air compressing will remain inside the pump and cause an overheat fast. in this case, you get to check your power connection or car battery, or you may want to start the engine during pumping.

    if the voltage is over 14V, the motor will run at its high limit and more heat will be general from the motor itself. but the motor can not use all the power and the extra power turns to the heat. High voltage will be found on many European cars or SUVs, in this case, you don't want to start the engine during pumping.

    You give you those note will help you the understand the pump in your application better. and when you hear the beep sound warning, you can look at its LCD screen and check with the user manual if questions. After a few uses, you should be able to work well with it. Thank you!

  • Tip

    Pro version air pump has the temperature sensor and voltage meter built in, once the temperature is too high over 80°C or voltage is out of range (9-15V), the pump will stop and beep sound warning, plus screen flash for a few seconds.  But since the pump stop, the temperature or voltage reading may get back to normal range very shortly, so the user may not be able to realize this pump self-protection. We suggest when you see the pump stop un-normally, you can stay closer to the pump and watch its screen when starting again. the screen can always show the real-time voltage, it will help you to find out the problem. On some European cars, we may not suggest starting the engine when pumping, since those car 12V sockets may give over 15V.  We also do not recommend starting the engine if the pump voltage reading can be over 10V during pumping. Since some old car generators may affect the pump sensor and digital control module.

    Special Feature of Seamax SUP Air Pump

    This air pump has the 1st Stage and 2nd Stage, when the pump starts from zero pressure, it will first start its 1st stage – turbofan unit, and it will turn into 2nd stage – Piston unit. 1st stage can blow up the air fast up to 350L per minute. Since we want the pump to maximize the 1st stage performance, so it can maximum shortage the waiting time during your pumping. Our best formula from lab testing is -  Pump will continue to check the pressure 10 times per second after reach 0.65 PSI. When the pressure difference is less than 0.05 PSI in a continuous 3 seconds, then the pump will know its first stage has already reached its maximum ability, so it cannot pump more air into the chamber, then it gets to switch to the 2nd stage to continue the pumping. 1st Stage max pressure output should be over 1 PSI.

    This feature will work great when the air chamber is big enough and with a regular marine air valve (H.R., Bravo, or Leafield). It can be suitable for all sport inflatable boats over 7ft that are equipped with an outboard motor and all inflatable SUPs. The individual air chamber of those products is all over 0.15CBM (5 Cubic Foot) and more. But when the air chamber is too small and less than 0.1 CBM (3.5 Cubic Foot), the reading from the pressure sensor will be jumping more when the pump max output is reached, so the pump may never detect a good signal of “pressure difference less than 0.05 PSI”.  In this case, the pump cannot switch to 2nd stage by itself. Since you may use this pump on a different product other than a sport boat or SUP. You can do the below operation to let the pump switch to the 2nd stage.

    • Stop the air pump manually, don’t need to disconnect the power. And you can restart the pump right away. When the pump detects pressure over 0.65 PSI from the air hose at starting. And if the read pressure doesn’t reach the set pressure value. The pump will start its 2nd stage directly.
    • You don’t have to stop the pump, during its pumping at 1st stage, you can press and hold the “Power ON” button for 3 seconds. Then the pump will be forced to switch to 2nd After you see the 2nd stage started, you can release your finger from the button.
    • If this is the SUP20MAX air pump, there is a 2nd stage button to press on the panel. It can directly turn on its 2nd Many inflatable products are using a small kind of air valve.  A small adaptor will bring lots of backpressures to the air pump and affect the pressure reading. You may have to force start the 2nd stage only. For example some of the inflatable Kayak, lifebuoy, and many water toys. That product may not be able to use the pump Auto Switch feature. FYI, A less expensive blower air pump without a pressure sensor and program control may even work better. 

    It may not be our pump defects if you see the pump won’t jump to the 2nd stage by itself. Please check our instructions carefully. Understanding our special program in its firmware is very important. Other than that, the air hose connects air leaking may cause a similar issue. So you get to make sure the connection is tight enough and choose the right size O ring. If you stop the pump and see the pressure reading dropping fast or/and hear the air leaking sound beside the hose. Then the connection may not be perfect yet. Use 5% liquid soapy water will help you to find air leaking easier.
