Operators must wear protective gloves and goggles, avoid pumping flammable liquids, ensure the pump is grounded, keep chemicals away from children and pets, and follow all warning labels.
Mount the pump according to the layout drawings, drill four 0.25″ holes, secure with #10 bolts and nuts, connect inlet and outlet piping using the specified sizes, and install a back‑pressure/injection valve as shown.
The pump remembers its last operating settings and automatically resumes the previous state when power is restored.
The pump is rated for a maximum pressure of 300 psi (20 bar).
