Check Valves & Controls
Before starting the pump engine, make sure the valves and controls are in the proper state.
- All discharge valves should be closed.
- A water source should be open, either the "Tank Suction" or "2.5 Inlet" Valve should be open.
- You will probably want to recirculate water right away, so the "Tank Fill" valve should be open.
- Foam tank selector should be in "Off" position.
- Pump Drain valve should be closed.
- Gauge Drain valve should be closed.
