APPENDIX — ST-45 PUMP RECOMMENDED SHOTCRETE SYSTEM
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.
