MAYCO LS400/LS500 PUMP — OPERATION AND PARTS MANUAL — REV. #6 (09/19/11) — PAGE 81
APPENDIX — 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.
