To avoid over heatig
It is to pressurize the fuel system and allows the vehicles fuel system to keep adequate pressure after the vehicle has been started.
Cycle the ignition on and off several times holding it in the on position for a few seconds each time. Doing this 4-5 times will allow the fuel pump to pressurize the fuel system.
Possibly over heating and worst case scenario a blown engine.
you can pressurize the system to find a leak
If you over-pressurize the system you could cause one of the hoses to burst or the system to leak at a mechanical coupling and cause the compressor to fail prematurely.
Air in the system. Bleed the cooling system and remove any trapped air pockets.
