a. Reduce the air pressure supplied to the Colo-
rant Tank by turning the regulator on top of the
tank in a counter-clockwise direction. Continue
to turn the regulator until the Tank Pressure
gauge indicates 0 psi.
b. Lift the pressure relief ring at the top of the tank
before removing four screws or unscrewing the
clamps that hold the Tank Cover in place.
c. Lift the cover off and lubricate or glue (using
RTV) the o-ring located in the groove on the
bottom of the cover.
d. Lift the colorant platen out of the tank if it is
installed. In some applications it might not be
used. (See Solvents, page 9).
e. Stir the pigment to the manufacturer require-
ments.
f.
Pour or scoop the colorant into the Colorant
Tank, filling it to the desired level. When filling
the tank, leave room for the platen if being used.
g. Place the platen, if needed, on top of the colo-
rant with the head of the screw facing up.
h. Place the Colorant Tank Cover back on the
tank. Be sure to seat the o-ring into the groove
before tightening the screws or clamps.

i.
Adjust the Colorant Tank Regulator to the
desired pressure. For 2000 centipoise colorant,
50 psi (345 kPa, 3.4 bar) should be sufficient.
To avoid machine damage and serious injury, do not
allow the colorant tank pressure to exceed 110 psi
(0.8 MPa, 8 bar).
j.
Attach the color line to the color injector using
the quick disconnect. The disconnect has check
mechanisms on both sides to prevent colorant
for pouring out when not attached.
k. Press and turn the manual actuator on the color
injector solenoid to move the piston inside the
injector to the inject position. Any air bubbles
that may be trapped inside the color injector to
the bleed port will be forced out.
l.
Place a clear, 1/4 x 12 in. (0.6 x 31 cm) tube
over the bleed valve to allow a visual of the
purging process.
m. Open the bleed valve and purge any air from
the injector when the color injector bleed valve
