Table 14: Pre-Operation Checklist

✓Checklist System grounded

Verify all grounding connections were made. See the Installation manual.

All connections tight and correct

Verify all electrical, fluid, air, and system connec- tions are tight and installed according to the Installation manual.

Check air purge valve tubing

Check the air purge valve supply tube daily for any visible solvent accumulation. Notify your supervisor if solvent is present.

Fluid supply containers filled

Check component A and B and solvent supply containers.

Mix manifold valves set

Check that mix manifold valves are set correctly. Start with the settings recommended in Mix Mani- fold Valve Settings, page 88, then adjust as needed.

Fluid supply valves open and pressure set

Component A and B fluid supply pressures should be equal unless one component is more viscous and requires a higher pressure setting.

Solenoid pressure set

75-100 psi inlet air supply (0.5-0.7 MPa, 5.2-7 bar)

2.Turn the AC Power Switch ON (I = ON, 0 = OFF).

I = ON

3.Verify that the EasyKey is working. The active rec- ipe number and Standby mode should be displayed.

4.If this is the first time starting up the system, purge it as instructed in Purging Fluid Supply System, page 96. The equipment was tested with lightweight oil, which should be flushed out to avoid contaminat- ing your material.

5.Make sure that the EasyKey is in Standby (remove Mix input).

6.Adjust component A and B fluid supplies

as needed for your application. Use low- est pressure possible.

7.Do not exceed the maximum rated work-

ing pressure shown on the system identification label or the lowest rated component in the system.

8.Open the fluid supply valves to the system.

9. Adjust the air pressure. Most appli- cations require about 80 psi (552

kPa, 5.5 bar) air pressure to operate properly. Do not use less than 75 psi (517 kPa, 5.2 bar).
