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.
