Spray one pint to one
quart of clean water
(distilled preferred) into
compressor inlet while
motoring engine without
ignition. Start injection 3
seconds prior to starter
engagement and

should have a quick
opening valve and a
nozzle which flows one
quart of water in 9 to 11
seconds. This flow rate
should allow the desired
quantity of water to be
injected by the time 10%
N1 speed is attained.
NOTE
A common garden sprayer can be
used provided the spray orifice is
sized to give the desired flow.
