Setup

Air Connections

Red and green 5/32 in. (4 mm) tubing connects the solenoid manifold to the pump’s dosing valves. See the Pump Tubing Schematic on the next page.

NOTE: Tubing lengths must be 18 in. ± 1/2 in. (457

mm± 13 mm) for all connections. Always use equal lengths of tubing, to balance the timing of the valves. Lengths longer than 18 in. (457 mm) will increase valve response time.

1.On the bottom of the solenoid manifold are four ports with tube fittings: UP OPEN, UP CLOSED, DOWN OPEN, and DOWN CLOSED. These ports provide air to open and close the pump’s inlet dosing valves.

Figure 4 Tubing Connections at Solenoid Manifold, to Pump Inlet Manifold

a.Connect green tubing (G) from the UP OPEN fitting to the 90° tube fitting on the side of the INLET UP dosing valve.

b.Connect red tubing (R) from the UP CLOSED fitting to the 90° tube fitting on the end of the INLET UP dosing valve.

c.Connect green tubing (G) from the DOWN OPEN fitting to the 90° tube fitting on the side of the INLET DOWN dosing valve.

d.Connect red tubing (R) from the DOWN CLOSED fitting to the 90° tube fitting on the end of the INLET DOWN dosing valve.

2.On the side of the solenoid manifold are four ports with 90° tube fittings (not shown): UP OPEN, UP CLOSED, DOWN OPEN, and DOWN CLOSED. These ports provide air to open and close the pump’s outlet dosing valves.

Figure 6 Tubing Connections at Solenoid Manifold, to Pump Outlet Manifold

a.Connect green tubing (G) from the UP OPEN fitting to the 90° tube fitting on the side of the OUTLET UP dosing valve.

b.Connect red tubing (R) from the UP CLOSED fitting to the 90° tube fitting on the end of the OUTLET UP dosing valve.
