The purpose of using this product is limited to the description in the owner's manual.
Be aware of your local recycle regulation for proper disposal of electronic products.
The pump's maximum air pressure is 20 PSI (1.378 Bar /138 Kilo-Pascal). The air pressure user setting is recorded in the pump memory when power disconnected. Before every use of this pump, it is user's solely responsibility to make sure that the pump is set to the desired air pressure. Incorrect air pressure setting may either under or over inflate the
inflatable product.
This pump is designed to use car cigarette lighter port or boat 12V DC socket. If you will use a portable battery, please make sure your pump’s battery fully charged before your trip. Also make sure the battery voltage is 12V. The max loading of power source can support 15 Amp current. The pump requires a minimum 12V, 7AH battery as power source to work properly.
Always check the air hose, valve connector, and the inflatable product before starting the pump. Do not block the Inflation port and Deflation port. This pump will make a loudly sound since its high pressure 2nd stage cylinder pumping unit.
This pump can auto switch from 1st stage to 2nd stage, or 2nd stage to 1st stage base on the pressure reading from its internal sensor. The switch point is set at 0.8 PSI.
The pump will auto stop after continuously running for 20 minutes. It is suggested to cool down the pump before its next continuous operation. Otherwise you must check the pump temperature before next use. For fast cool down the pump, you can turn on the air pump to let it work in the air for 1 minute.
If you have to return the product, please first contact with Seamax Marine or the dealer that you purchase it from. Repairs may only be performed by an authorized service technician. The manufacturer is not responsible for damage caused as a result of improper use or failure to observe these instructions.
This pump shall not be exposed to the rain or immersed in water. Do NOT leave the pump unattended while inflating.
Built-in audible indicator and special message display on LCD screen to notice the pump’s status: Startup, Stop, Error, Overheat, High voltage and Low voltage
Input voltage real time monitoring system. Pump normal working voltage range is 9V-15V. This pump will stop working or won’t start if the voltage is below 9V or over 15V. If the input voltage is too low, the pump will not have enough power to inflate your inflatable product’s air chamber to a higher pressure fast enough. Such situation will easily cause the pump’s piston overheat damage. If the input voltage is too high, it will cause motor overheat issue and burn the pump electronic components. ERROR icon and voltage reading will keep blinking when voltage issue detected. The pump will be back to normal after the detected voltage is within its safe working range (9 to 15V).
Overheat protection. When the pump’s internal temperature reaches 85 Celsius degree (85°C or 185°F), the pump will stop working immediately. And the pump “Start Up” feature will be locked for temporary Self-Protection. The LCD screen will show a
flashing ERROR – OVERHEAT message. The pump will be automatically unlocked after its internal temperature drops below 50°C (122°F). To bypass this waiting period, user can reconnect its power plug to reset the pump. Disconnect the air hose and turn on the pump in cool air for 3 minutes for fast cooling down before pumping again.
When the air pressure is over 5 PSI and below the user’s set pressure, the pump will start monitoring the pressure
increment. If the pressure increment is less than 0.05 PSI after 20 seconds continuous running, the Pump Self-Protection will be activated and stop working. User should check all the connection and O Rings size to make sure all components’ air tight and right fit, before start pumping again. If without this self-protection, the inflator could be permanently damaged
in few minutes.
The pump will stop automatically after 20 minutes continuous running regardless the pump’s working stage and condition.
Please make sure the following accessories are provided in the box. In case of any parts missing, please contact the original seller or Seamax. Spend some time to study this manual and experience all the pump functions especially how to properly set the target air pressure before trying to inflate a product.
Select a valve adapter and an O-Ring with correct thickness to fit your inflatable product’s air valve.
You can use your original valve adapter if it provides better inflation result than using the ones provided with the pump. To modify the valve connector won’t affect your pump existing warranty coverage.
Test Run is necessary before the first time use. You can stop the pump any time by pressing its power button. Do NOT leave the pump running unattended even considering its auto stop feature!
Do NOT let the pump running for more than 20 minutes continuously. Inflate one SUP / Paddle Boat at a time. Extended usage beyond its recommended continuous running time can cause overheating and damage the internal inflator.
Using smaller valve fittings limits the airflow speed, so the pump will be easier to get overheated. User's attention is very important for this type of application. The max 20 minutes continuous working time must be reduced accordingly.
Low quality instable power source will decrease the pump running performance. The needed time to complete inflating a product will be increased. This can cause overheating issue and damage the pump's inflator quickly. Do NOT operate the pump with any low capacity, low voltage, and low quality battery.
If the air hose section near the pump port is getting warmer such as over 60ºC (92ºF), stop using the pump immediately to let it cool down first.
If the environment temperature is too high, the pump's maximum continuous working time shall be reduced accordingly.
Plug the pump power adapter into the car's 12V DC socket, or to a battery with a convertor.
Connect the end with flexible conduit adaptor (1) of the air hose with the air pump inflation port (1), and twist clockwise to tighten it (Figure 1).
Connect the other end of the air hose with an air valve adapter. Insert it into the supported product's air valve and twist clockwise to fix it (Figure 2).
Press the air pressure unit toggle button [PSI/BAR] to select your preferred unit such PSI or BAR.
Press the Increase Air Pressure button [+] or Decrease Air Pressure button [-] to set the desired target pressure value matching with your inflatable product's air pressure requirement from 0.5 PSI to 20 PSI (1PSI=0.0689BAR).
The pressure setting increasement is 0.5 PSI. Press the On/Off power switch button to start the pump.
During the inflating process, you can press the Increase Air Pressure button [+] or Decrease Air Pressure Button [-] to adjust the target air pressure value. Press the Air Pressure Unit toggle button [PSI/BAR] to switch the air pressure unit. Pressing the On/Off power button can stop pumping manually.
During the inflating process, the LCD screen displays the inflatable product’s on-going real time air pressure. The preset target air pressure number will appear in every 3 seconds in flashing mode for the user’s information.
Remove the hose from the inflation port. Connect the end with flexible conduit adaptor (11) of the hose with the air pump deflation port (2). Twist clockwise to tighten it (Figure 3). The other end shall still be to the inflatable product.
Press the On/Off Power Button to start the deflation until all the air inside the inflatable product is discharged. Turn off the air pump to stop the deflation.
This new version of SUP20D Air pump is equipped with a special Smart Pressure Monitoring Feature. Once the pressure reading reaches 0.6 PSI when inflating in the 1ST stage, the program will start monitoring the pressure increasement. If the pressure increasement is less than 0.03 PSI in a period of continuous 6 seconds, the internal controller sees the 1ST stage is reaching its max inflation capacity. Then the pump will receive a signal to stop the 1st stage and start the 2nd stage inflation by the piston compressor.
Based on the new program, this pump can provide the best inflation efficiency for inflatable SUP, boat, kite, tent and any kinds of inflatable tops provided using a suitable air valve adapter and max 20 PSI pressure requirement met. It saves user’s time and energy to quickly inflate the product to the targeted PSI.
To best utilize this function in the proper way, a good condition qualified power source is necessary to suppor the pump. During the whole inflation process, users need to make sure the air tightness and minimized air leaking along the air passage from the pump’s inflation port to your inflatable product through the air hose connection.
In case the pump could not automatically switch to the 2nd stage, user can stop the pump and make sure the chamber reading pressure can be over 0.6PSI, and you start the pump again to activate the 2nd stage manually. If the pump detects over 0.6 PSI pressure when started, it will bypass the 1st stage and switch to the 2nd stage for high pressure pumping directly.
Tips: if the 1st stage could not start properly in some unsual situation, user can use a manual pump to inflate the product to about 1 PSI, and then use this pump to do the rest of the inflation proess directly starting from tis 2nd stage.
When the air pressure is over 5 PSI, the pump will start the monitoring program again. If the pressure increasement rate start to decrese for a set period of time or the internal tempreture is over 85 Celsius (185 Fahrenheit), the internal protection mode will be activated. The pump will stop automatically to avoid over heating issue.
Reconnect the Power Cord for fast check before troubleshotting!
Most of the issue may be caused by low power voltage or weak 12V connection. Continuous usage of the pump in such condition can easily damage the pump’s 2nd stage compressor due to overheating issue. Before solving the inferior power source issue, user shall not use the pump in the same condition for over 3 minutes. Following guideline can help users perform basic troubleshooting steps.
If not done yet, use your car’s battery as the power source. This pump needs a good battery to continuosly provide 15 Amp output for its 12 Amp power consumption. Do NOT use a small 110V to 12V DC convertor even they are 15A rate.
If the car battery is over 2 years old or purchased as used, you can turn on the engine when pumping and see any difference. Best you can check the battery voltage with Digital Electric Multimeter and make sure battery voltage over 12V.
You should check your air hose connection of air tight. Make sure you put a right size O ring on the valve adaptor. When you turn off the pump with a certain pressure remain in the SUP chamber, do not disconnect the hose, you should not hear any air leaking from the connection in both side of hose. You can also use 5% soapy water to check to verify the air leaking.
Tune up your 12V socket is very important, you can shiny the socket by using Sand Paper. Lighting cigarette can make the 12V socked with extra electrical resistance. Even a GPS is working fine, but it may not be good enough for this pump since 12Amp needed. So we want you to check this part or change another socket or vehicle to try.
You can discuss with us for any other problems. Otherwise if your pump had been checked and no more high pressure created. we believe your pump had been damaged. Then you get to contact us via email directly for repair or replacement. You can find our email from Seamax Marine website or the pump user manual.

And you may need to pay for the shipping and handling cost if your purchase is over 60 days and return the original pump. Thanks again for contact Seamax.
This pump is suitable for the products with HR (Halkey-Roberts), Bravo or similar air valve. They are the most popular air valves for the inflatable SUPs and paddle boards in the current market. This type of air valve has a center turning pin (HR valve) or pushing pin (Bravo) control the air valve’s Open / Close position. The universal valve adapter supplied with the pump shall fit it.
Please make sure the air valve is in its Close position when inflating the air chamber. Otherwise, some air may leak from the valve when the air hose is being disconnected. Our air pump comes with universal HR valve adaptor with 3 different thickness Silicon Rubber O-Rings (3mm/5mm/6mm ). The 6mm O-ring is per-installed on the air hose valve adaptor. It should have one to fit your air valve best and air tight.
If you cannot use our valve adapter for your inflatable product, you may have to cut the hose to install yours from the original manual pump. You can use the electric tape to ensure the diameter fit and tight. You can also contact with
Seamax Marine to apply a set of Free Air Hose for this modification.
After use, or if you want to move, maintain or adjust the product, first pull out the DC plug from the socket. Clean all dirt from the pump. If the pump gets wet, let it dry in the air before packing it into a carrying bag.
