SPECIAL SMART PRESSURE MONITORING
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.
