ATOMIZER ASSEMBLY
REMOVAL/REPLACEMENT
(MCV STYLE)
To quickly remove the turbine and valve assembly
section from the mounting manifold, first make
sure that fluid passages are cleaned and flushed
if possible. Ensure that the turbine has stopped
spinning and that the high voltage is turned off.
Turn off bearing air supply and relieve or turn any
other air or fluid pressures off and allow to bleed
down. Hold the turbine assembly with one hand
underneath the unit for support. Use your other
hand to release the three (3) clips by lifting the
back edge. Pull the atomizer assembly straight
away from the manifold.
To replace the atomizer assembly, first verify
that the three (3) o-rings are present in the valve
manifold assembly, one for the cup, paint, and
solvent inlet. Examine the mating o-rings on
the manifold pipettes, ensure that they are not
damaged. Align the "black" colored pin on the
valve manifold with the groove in the mounting
manifold. Press firmly into place. Push down
on the front of the clip until it is over the keeper
button. Next, push down on the rear of the clip
until it snaps into place. Repeat this for the other
two (2) clips.
Turn bearing air back on and make sure that the
bell cup rotates freely by hand.
