T
he problem for many M17 decons is
that they sit ignored until they're need-
ed. When problems are discovered, it's
too late to solve them before you go to
the field.
SBCCOM recommends this monthly
checkup for all your M17s to catch and
solve problems before it's mission time:
a.
Verify the water pressure
is 45 psi (± 5).
b.
Verify both LEDs light up
c.
Verify the burner goes out
when the water temperature
reaches 45° C.
d.
Heat the water to 45°
three more times. Make sure
the burner lights and shuts
down each time.
6.
Install the showers and run the engine at maximum
speed. Set the function selector to SHOWERS.
7.
Remove the showers and run the
engine at maximum speed. Set the
function selector switch to SHOWERS.
8.
Remove the inlet and branch
hoses, run the engine at maximum
speed for no more than 30 seconds
to purge the water. Stop the engine.
a.
Verify the burner will
not ignite.
b.
Briefly hit the LOW
PRESSURE OVERRIDE switch
and verify the burner ignites.
c.
Set the function selector
switch to OFF and reduce the
engine speed to idle.
5.
Set the function selector
switch to OFF. Squeeze both
wands to circulate cool water
until the water temperature
is below 40° C. Reduce the
engine speed to idle and
remove the wands.
Do these
eight steps
every month
and your M1
7
will be ready
for duty.
