Graco 3A1705J Electrical Connections, Connect Feed Pumps, Breathing Air

Electrical Connections

Connect air compressor, breathing air, and auxiliary power electrical connections to the specified circuit breakers. See Circuit Breakers, page 28.

1.Remove one or more knock-outs on side of electrical enclosure, as required, and route wires through for air compressor, breathing air, and auxiliary equipment. See Circuit Breaker Configuration Options, page 29, for more information.

Connect Feed Pumps

1.Install feed pumps (K) in component A and B supply drums. See

Typical Installation, with circulation, page 13 and Typical Installation, without circulation, page 14.

2.Seal component A drum and use desiccant dryer

(M)in vent.

3.Install agitator (L) in component B drum, if necessary.

4.Connect supply hoses from feed pumps to the component A and component B material inlets on the system. Ensure A and B inlet valves are closed.

Note

Note

Agitator air supply (PH) includes a small internal restriction orifice to limit the air flow to minimize air compressor load. Maximum supplied air flow is 2.0 scfm (0.1 m3/min) at 100 psi (0.7 MPa, 7 bar). Designed for use with Twistork agitator 224854. Do not use the agitator air outlet (PH) for any other component.

Breathing Air

Breathing the air from the compressed air supply can cause serious injury if inhaled.

•Only use an independent and approved breathing air system with adequate air flow to provide clean breathable air.
