TORO Hydroject® 3000/4000 Water System Operation

NOTES

____________________________________________________________________________________________________________

System Operation

1. Water is supplied to the unit by a water supply hose or a portable water supply tank.

2. The water passes through the pre-filter

3. On the Hydroject® 3000 the inlet water flows to the pressure-reducing valve, where the water pressure is

reduced to 90 PSI.

4. The Hydroject® 4000 does not have the pressure-reducing valve, it is replaced by a water boost pump. The

boost pump supplies water to the unit.

5. The water then flows through the main 5-micron inlet filter.

6. The water then flows to an engine driven water pump. The water pump is capable of delivering water in

excess of 5000 PSI.

7. The water is then pumped to the accumulator. The accumulator stores the high-pressure water until it is

needed at the aeration nozzles.

8. The relief valve limits the water pressure to 5000 PSI.

9. The water valve (cycling valve) is a cam-operated valve driven by the unit’s engine. This valve opens and

closes to direct the high-pressure water stream to the aeration nozzles.

10. From the cycling valve the water flows to the aeration nozzles, the nozzles contain a spring-loaded check

ball which prevents water from leaking out of the manifold and air getting in the system.
