How do I set the phase and direction on a three-phase Step-Up 120?

Plug in, shut the spray jet valve and set the main switch to 1; a blue lamp confirms the line has power. Next pick position 1 or 2 on the phase switch. If the screw rotates the way the manual's figure shows, the phase is right. The other position runs the screw backwards, which is exactly what you use when you need to dump pressure from the hose. A separate switch chooses motor speed 1 or 2. Open the air valve at the jet, or use the remote, and the pump starts turning slowly. Stop once grout has climbed to the mixer, fill the hopper and begin work. If the red lamp is lit, the grid or vibro-screen is missing or seated wrongly.
