Instructions for 242-95 portable eductor
The Elkhart 242-95 Eductor is a device used for educting a liquid concentrate solution into the
water stream of 1-1/2" fire hose lines.
The 242-95 Eductor is constructed of Armor-Lyte ™ composite material with stainless steel
components for resilience and durability. Armor-Lyte
™ is impervious to the corrosion caused by
high concentrate detergents, salt water and most chemicals.
The 242-95 Eductor is designed for use with nozzles calibrated for flow rates of 95gpm (356
lpm) at 100 psi (6.9 bar). Each Eductor comes equipped with a 1-1/2" NHT female swivel inlet
connection, a 1-1/2" NHT male outlet connection. The eductor comes with four metering/check
valves to choose from ( 1/2%, 1%, or 3% fixed orifice) or (1/2%, 1%, & 3% adjustable). Each
metering/check valve has a 3/4" male Garden Hose Thread inlet that the concentrate pick-up hose
assembly will attach to.
Installing a fixed orifice metering/check valve. Each of the three different fixed orifice
metering/check valves provides a different concentrate eduction rate. When installed, the Black
metering/check valve will educt at a 1/2% rate, the Purple metering/check valve will educt at a 1%
rate and the Green metering/check valve is for educting at a 3% rate. To install a fixed orifice
metering/check valve screw the male thread located on the end of the metering/check valve from
which the inner coil spring is visible into the female thread on the side of the eductor body as far
as possible by hand. Then gently grasp the metering/check valve body with pliers or vise grips
and tighten snuggly. There is no need to over tighten.
To remove a fixed orifice metering/check valve,
gently grasp the checkvalve body with pliers or vise
grips and unscrew. The illustration to the right
shows the method of removing the fixed orifice
metering/check valves.
Installing the adjustable metering/check valve. Screw the male thread
located on the end of the adjustable metering/check valve with the chrome
position indicator label. (On the illustration to the right it’s shown at the top.)
Tighten snuggly by hand only no tools are needed. There is no need to over
tighten.
Operating the adjustable metering/check valve. Rotate the red selector
ring to align it’s pointer with the desired eduction rate on the chrome label. The
red half dot indicates the 1/2% position, the red full dot indicates the 1%
position, and the three red dots indicate the 3% position. There is no OFF position.
