| 12V Electric Air Pump Digital Control for Inflatable Boats |
This pump delivers a constant flow of air up to 500 L per minute and comes with set of different adapters for inflatable boats including Halkey-Roberts Valve adapter commonly found on inflatable dinghies.
The wiring for the inflator will need to be connected directly to 12 volt Direct Current (DC) battery with minimum capacity 5 ah . Electric pump can be used with car battery ,deep cycle trolling motor battery or marine battery for your boat or watercraft.
When the pump starts it will be on a HIGH VOLUME (Turbine) pump until the pressure reaches 2-3 PSI. Then the pump will automatically switch over to the HIGH PRESSURE (Piston) pump and inflate the boat to its set pressure. Once a set pressure reached the pump will automatically turn itself off. During operation , the actual pressure is shown as a number in Kpa on the left side of the LED display .
Compact Three Button Digital Inflation Operation
1. Choose the proper fitting for the air valve of your inflatable product. Put the valve at the inflation position. Attach the correct valve adaptor to the inflation hose that comes with your pump. Attach the other end to the pump (smooth round outlet on the pump)
2. Connect th as used for the 80D model.e 80D pump¨s terminals to the battery paying close attention to the polarity. Make sure the clips are on the same color electrode and properly connected. Otherwise the pump won¨t turn on or run properly.
3. If you have the model with the built-in battery (80DB / 80DB-Li), please make sure the battery has been charged. A new fully charged battery should last 30 minutes or more with regular use. If the battery is low, you can use the extension 12V cable that comes with your pump and connect them to your 12 volt battery. Follow the same instructions
4. Turn on the POWER switch and enter the maximum desired pressure by using the two set pressure (UP / DOWN) buttons, the set pressure will be shown on the right hand side of LCD screen. The pump only provides Mode KPa as its pressure display. (10KPa = 100mbr = 1.45 PSI). Factory default working pressure is set as 25kpa (3.6 PSI).This pressure is suitable for most inflatable boats.
5. Press the POWER button to start. During inflation, the left hand side of LCD screen should show the pressure that the inflator has reached. As soon as the entered pressure has been reached, the inflator turns off automatically. And the inflator can be turned off at any time by pressing the POWER button again. Take off the air hose from the chamber once the pump stops pumping. It is possible to stop the inflator at any time by pressing the (OFF) switch.
6. The inflator operates in two stages which can be identified by the noise of the turbine at the beginning followed by the piston. The inflator switches from turbine to piston automatically. If the chamber pressure is over 7Kpa / 1 PSI, the pump will start the 2nd stage only. If the set pressure is lower than the chamber¨s pressure, the pump won¨t turn on.
Extra Feature - Deflation Operation
If you can use the pump to inflate the chamber, you can use it to deflate the same chamber too. First following the Step 1/2/3 as above. Attach the yellow hose onto the deflation side of the inflator (round outlet with notches). Attach the other end to the chamber you wish to deflate.
