See the System Pneumatic Schematic on page 66 (hazardous location) or page 67 (non-hazardous loca- tion).

1.Tighten all ProMix 2KE system air and fluid line con- nections as they may have loosened during ship- ment.

2.Connect the main air supply line to the main air inlet. This air line supplies the solenoids, valves, and pumps. See FIG. 3.

FIG. 3. Air Supply Inlet

3.For each gun in the system, connect a separate clean air supply line to the air inlet of the air flow switch. This air supplies gun atomizing air. The air flow switch detects air flow to the gun and signals the controller when the gun is being triggered.

Fluid Supply

Requirements

•Do not exceed the pressure rating of the lowest rated component. See the identification label.

•To reduce the risk of injury, including fluid injection, you must install a shutoff valve between each fluid supply line and the mix manifold. Use the valves to shut off fluid during maintenance and service.

ProMix 2KE models are available to operate airless (high pressure, 50 cc pumps only), air spray, or air-assisted systems with a capacity of up to 3800 cc/min.

•Fluid supply pressure tanks, feed pumps, or circu- lating systems can be used.

•Materials can be transferred from their original con- tainers or from a central paint recirculating line.

NOTE: The fluid supply must be free of pressure spikes, which are commonly caused by pump stroke change- over. If necessary, install pressure regulators or a surge tank on the ProMix 2KE fluid inlets to reduce pulsation. Contact your Graco distributor for additional information.

Fluid Connections

1.See FIG. 5, page 15. Connect the solvent supply line to the 1/4 npt(f) solvent valve inlets (SVA and SVB).

2.Connect the component A supply line(s) to the com- ponent A dose valve inlet (DVA).

NOTE: Paint Recirculating System Only

•If you are recirculating paint, use the standard inlet on Dose Valve A or Dose Valve B. Remove the plug directly opposite it on the dose valve for the recircu- lation outlet. See FIG. 5.

3.Connect the component B line to the component B dose valve inlet (DVB).
