See that the injector is shut off when put on, by turning the handle
as far to the right as it will go. To start, turn handle to the left
one-quarter turn; when the water appears at the overflow, turn the
handle slowly to the left as far as it will go, and the injector will
be working to the boiler.
[Illustration: American World Injector.]
If steam is high and lift long, the injector will lift the water
better if the handle is turned a little less than a quarter of a turn,
until the water appears at overflow—then start to boiler as before.
If you have valves in steam and suction pipes, be sure and open them
before starting.
Q. How high will an injector draw its supply?
A. About twenty feet is the limit.
Q. How hot does an injector deliver water?
A. From 150 degrees to 200 degrees, according to the steam pressure and
the proportions of its capacity at which injector is working.
Q. How should the jets be cleaned when they become scaled?
A. By soaking in diluted muriated acid, about one part acid to ten
parts water.
