Operation
1. Ensure that a nozzle assembly with appropriate size
orifice is installed. See
Orifice Size Selection sec-
tion on page 13.
2. Turn on material pumps so that material will begin to
flow through the MixHead.
3. Rotate the injection adjustment screw to adjust
chemical pressures. If the injection adjustment
screw (104) is locked in position, break loose the
hex locknut (103) from the injection nozzle retainer
(102) to free the adjustment screw.
4. Tighten the hex locknut (103) against the injection
nozzle retainer (102). This will lock the injection
adjustment screw position.
Do not come into contact with Isocyanate. See Iso-
cyanate Hazard on page 5.
Pressure setting is an operator adjustment and
mixing pressures for of 2000-2200 psi (13.5-15.0
MPa, 135-150 bar) are recommended. Contact
your chemical system supplier for more detailed
information.
CAUTION
Do not over-adjust the injection adjustment screw and
close the needle valve into the orifice of the needle
housing. This will damage the injection needle and
orifice.
Do not use the needle valve as a shutoff valve.
