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.

About Deflation

To do the deflation, you should not connect the pump to your SUP right the way. Before you use the electric air pump, You should press open the air valve on SUP and lock it at the open position. First to let the SUP leak out all the high-pressure air until zero pressure. You may only need few seconds to see the SUP getting flat after the loud air leaking sound. Then you connect the hose to the SUP to do the final deflation, suck the rest air out until your SUP in a small easy packing size.

Connect the air hose to the pump deflation port and SUP, press the Power On button and let the pump run only at its 1stage (turbofan). So it can suck the air out very fast and be completed in less than 1 minute. Don't let the pump run at the 2nd stage (hold the power button can force the pump directly run at 2nd stage), Since 2nd stage air intake is from the pump internal but not from the deflation port. So you won't be able to deflate your SUP successfully if running at the 2nd stage.

We do not suggest to over deflate your SUP since it could cause SUP seam damage or pump overheat damage. Keep the valve in an open position when you roll it up. But Don't forget the close the air valve before the next pumping.

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 Double Stage 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. 1^st 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 2^nd 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 2^nd stage directly.
- You don’t have to stop the pump, during its pumping at 1^st stage, you can press and hold the “Power ON” button for 3 seconds. Then the pump will be forced to switch to 2^nd After you see the 2^nd stage started, you can release your finger from the button.
- If this is the SUP20MAX air pump, there is a 2^nd stage button to press on the panel. It can directly turn on its 2^nd 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 2^nd 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 2^nd 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.

- 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 2^nd stage directly.
- You don’t have to stop the pump, during its pumping at 1^st stage, you can press and hold the “Power ON” button for 3 seconds. Then the pump will be forced to switch to 2^nd After you see the 2^nd stage started, you can release your finger from the button.
- If this is the SUP20MAX air pump, there is a 2^nd stage button to press on the panel. It can directly turn on its 2^nd 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 2^nd 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 2^nd 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.

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 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.

About Deflation

To do the deflation, you should not connect the pump to your SUP right the way. Before you use the electric air pump, You should press open the air valve on SUP and lock it at the open position. First to let the SUP leak out all the high-pressure air until zero pressure. You may only need few seconds to see the SUP getting flat after the loud air leaking sound. Then you connect the hose to the SUP to do the final deflation, suck the rest air out until your SUP is in a small easy packing size.

Connect the air hose to the pump deflation port and SUP, press the Power On button, and let the pump run only at its 1stage (turbofan). So it can suck the air out very fast and be completed in less than 1 minute. Don't let the pump run at the 2nd stage (hold the power button can force the pump directly run at 2nd stage), Since 2nd stage air intake is from the pump internal but not from the deflation port. So you won't be able to deflate your SUP successfully if running at the 2nd stage.

We do not suggest to over deflate your SUP since it could cause SUP seam damage or pump overheat damage. Keep the valve in an open position when you roll it up. But Don't forget the close the air valve before the next pumping.

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!
Tips
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 Double Stage 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. 1^st 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 2^nd 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 2^nd stage directly.
- You don’t have to stop the pump, during its pumping at 1^st stage, you can press and hold the “Power ON” button for 3 seconds. Then the pump will be forced to switch to 2^nd After you see the 2^nd stage started, you can release your finger from the button.
- If this is the SUP20MAX air pump, there is a 2^nd stage button to press on the panel. It can directly turn on its 2^nd 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 2^nd 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 2^nd stage by itself. Please check our instructions carefully.

5FT reinforced air hose for high pressure inflation
2x O-ring with different thickness
Reinforced hose-to-Pump adapter
Reinforced Halkey-Roberts valve adapter
With Leafield C7 compatible valve fitting adapter

Operation Instructions

1) Higher pressure output causes air temperature goes up fast. Higher temperature and slower air flow may damage the pump and air hose. Do NOT use the pump after a continuous running for more than 5 minutes at the setting of 8 PSI or higher. Let the overheated pump cool down for at least 15 minutes before next use.

2) Make sure the pump's internal battery (if applicable) or external battery is fully charged before operating the pump. Battery in low level will cause longer working time and damage to the pump's internal parts.

3) To cool down the pump fast, let the pump operate a few minutes without connecting the hose to it. The air flow may cool it down faster.

4) If the hose is damaged due to the hot air near the hose-to-pump connector, cut the damaged portion (approximate 2-inches) and use the new extra hose-to-pump connector.

Pump Parts #1 - Digital Program LCD Unit for SUP20D PRO & SUP20S PRO Air Pump (DPU)

34.00 USD

First to Know -

Digital Program LCD Unit (DPU) for SUP20D PRO & SUP20S PRO. Those 2 models are share with this same parts, Those version of air pumps also come with temperature sensor and voltage gauge built-in.

This parts may not be able to compatible with our previous version SUP20D or SUP20S that without those new features built-in (2018 or 2019 version). Or if you have an old version pump, you may want to purchase it with the new PCB (Power Control Board) together and make sure all matches. Additional cost may be applied.

Instructions of replacement -

First open the air pump housing from its 6 screws at the back, the DPU is located at the handle from the top housing. There is a screw or locking hook under the handle, you get to remove this lock-in screw before you can access the old DPU. some of the front handle's top trim cover may use the glue to seal tight, so you may have to bend the trim cover harder before you can fully access the old DPU. And you only need to connect the white data bank cable to make it work.

Our DPU is not easy to damage, usually if this parts was damaged, you may have your pump with physical damage or water damage, then you may have to replace this DPU parts. Or it is the version issue that you get to change it to match the new PCB.

Tips -

To prevent the damage of DPU, just protect your air pump well during use and transportation. Also know the best working voltage range is 10-14V for these air pumps. Always check the voltage reading from the LCD screen when pumping. If you use the pump with your car, you may want to start the engine when voltage showing below 10V, or you should not turn on the engine if the reading already over 14V. Both low voltage or high voltage will be shortage the pump life time. and the pump will be stopped or won't be able to start if voltage out of range (9-15V). You may need to find out the reason if voltage out of range.

If you have our earlier version air pump, the power plug housing could be a different version. but the internal parts should be the same or very similar, many internal parts are universal.

If you can replace a whole brand new plug. then you may need to know how to use the Soldering Iron tool, you can re-connect the power wire by using this new plug. Make sure the negative and positive wires do not cross over if you need to re-connect the wire, otherwise your pump's PCB could be damaged.

2 Main Repairs Instruction

We may provide you a complete plug assembly, including the positive steel bracket and negative steel bracket inside the plug. In most cases, you may only need to use some of the parts from this brand new plug assembly, such as the top tip and cap, fuse, and spring.

Before reading the repair instruction, we suggest you can use a small plier to check the screw-in cap tighten once in a while (turn the cap clockwise). since the plug's top cap may get loosed when connecting to the car or transportation. And you may lose the cap and another related small component once the cap missing.

1). Lost of top parts - Once the cap is loosed, you may lose the top cap, contact tip, fuse, and more. If the plug housing has no problem. you may only need to take out the missing parts from the new plug and place them back to your old plug. The correct inserting order should be fuse (or spring and fuse on old models), housing ring, contact tip, and top cap. Please read the photo.

You can place the fuse tube back first, and put the contact tip inside the cap, screw them all together back to the old plug. If you also lost the steel lock ring on the plug, you get to place it at first before screwing in the cap.

2), Other Problem - you may need to open your plug if you have other problems including the plug housing burn or damage, spring issue, or any kind of connection problem. you may learn from the new plug before you can start opening the old one.

Get to know that the plug black housing is including 2 main components, we can call it Male Cap Side and Female Cap Side. The female cap side is the side that you taking out the bolt, the male cap side is the other side holding the nut of the plug housing. Those 2 parts are looking similar, but their structure is different when you can look at them in detail. Only the Male Cap Side has 2 poles to hold the pair of outside negative contact spring. you will put all the parts from this side before you can close the cap properly. Please check our photos for more detail.

Final Step

Always learn from our photos and your parts before repair the power plug, after the assembling, best you can have an electrical meter to check if any circuit shortage on your plug. Measure the electric resistance value from the negative and position plug contact. If the reading is 0.01 to 2 Ohm, it must be something wrong.

Warning

If you make a mistake by giving the circuit shortage. It will cause your car fuse to burn out or fire from the power plug. It will be hassle and digamous. So, most important is you get to check all parts are in place before closing the housing.

Always check if this pump's power plug is pushed tight and solid in the car cigarette port, so the plug can have a good electrical contact during working. get to know the pump will draw 10A from power. Loosed connections including the top cap loosed may cause over-heat and fire. so your attention during pump working is very important. you can check the temperature of the plug during your pumping. if you feel very hot, then you get to turn off the pump right the way.

You also need to make sure the car cigarette lighter port is shiny and has no dirt to block the contact. your port could work fine with a small power device such as USB charger. but the pump will have a much higher requirement. Use sandpaper to shiny the internal port will be an easy way to do a quick tune-up.

And if you feel something is wrong or are not sure, please open the plug to check or contact us with some photos. support@seamaxmarine.com

Also, work on the table and don't lose any parts during the work. since the components are small, please make sure enough lighting and wear your glasses.
