The airconditioner constantly uses a small amount of water, so the pump cycles often but for a very short time.
I have a 240VAC to 24V Meanwell supply. The adjustment for my unit and looking at the diagram for your supply should be between the screw terminal and the power on LED. It might be worth trying the pump with the lowest voltage that the supply will put out to see if it will work.
Regarding the short run time. It might be worthwhile putting in a delay timer that would delay the pump restarting for whatever time it takes the evap cooler to say half empty the tank.
Is the motor power wired directly through the float switch, if so is it rated to handle the 30+ amps of inrush current?
I'll try fitting a battery inline,
When you say inline I assume you mean in parallel with the power supply. It might be worth putting a 30A fuse from the + terminal of the battery.
