General recommendations

■If the site will permit, use steel pipe from the pump to the pool perimeter. It will reduce line pressures which is highly recommended.

■The vibrator on the reducer by the pool improves pumpability.

■Turn both air vibrators off whenever the pump is stopped to prevent separation of mix.

■The air vibrators are low consumption (4.2 scfm).

■Leave the air on at the nozzle when the pump is stopped to prevent clogging of air the hoses in the air insert.

■Use item #11 (steel elbow) at the edge of the pool to prevent collapse of the rubber hose, which can cause blockage.
