2. Attach regulated solvent supply lines as follows:
• Multiple Multiple color/single Multiple color/single color/single catalyst
color side, do not disconnect the color supply
line from the inlet manifold of Pump A. Instead,
connect a regulated solvent supply line to the
designated solvent valve on the color valve
manifold. On the catalyst side, disconnect
the catalyst supply line from the inlet manifold
of Pump B, and connect a regulated solvent
supply line.
Multiple color/multiple color/multiple catalyst
• Multiple Multiple color/multiple
Connect regulated solvent supply lines to
the designated solvent valves on the color
and catalyst valve manifolds. Do not connect
solvent supply lines directly to the inlet
manifolds of the pumps.
3. Set the solvent supply pressure regulator at the
lowest pressure possible. Generally a setting
of 25–50 psi (0.18–0.35 MPa, 1.8–3.5 bar) is
sufficient.
4. On the ADM, go to the Fill screen for Mix Unit
#1. Select Color (A). Enter the color number in
the box to the right.
