INJECTOR INSTALLATION
FOR PRESSURE WASHING
Installed as shown above, injector will produce a high pressure hot water discharge up to 200°F.
Balance between injector capacity and total nozzle discharge capacity is important.
With proper size nozzle, and using dry steam for operation, discharge pressures equal to or even
greater than boiler pressures are obtainable.
When operating, steam valve should be open wide and water supply valve throttled to suit discharge
flow.
For ordinary conditions, reducing valves on the water supply line are not necessary, however if a re-
ducing valve is used, its capacity should be checked to ascertain that the flow will be sufficient for
proper operation.
It is important to use dry steam.
To start operation: Open water supply valve, then open steam valve wide; next, throttle water supply
valve until injector quits spilling at overflow.
