Setup
1. Connect the air supply to the main air inlet (K) on
the control box. Air supply must include a
shut-off/bleed valve that bleeds pressure past the
shut-off/bleed valve and an air-water

2. Connect air lines from the control box to the
dispense valve. Match the number and color codes
on the fittings and connections. See the following
table and illustration.
3. Connect the Dispense Valve I/O and Start Options
logic cables. If level controls are installed, connect
the Level Controls logic cables.
4. Adjust the air pressure regulator to 80 psi (0.6 MPa,
6 bar).
5. Perform the

procedure for the dispense valve
and feed system components. See
