Purging

Read Warnings, page 9. Follow the Grounding instructions in your system Installation manual.

To avoid splashing fluid in the eyes, wear eye protec- tion.

There are 4 purging procedures in this manual:

•Purging Mixed Material (below)

•Purging Using Recipe 0 (page 96)

•Purging Fluid Supply System (page 96)

•Purging Sampling Valves and Tubes (page 98)

Use the criteria listed in each procedure to determine which procedure to use.

System Operation

2.Set the solvent supply pressure regulator at a pres- sure high enough to completely purge the system in a reasonable amount of time but low enough to avoid splashing or an injection injury. Generally, a setting of 100 psi (0.7 MPa, 7 bar) is sufficient.

3.If using a gun flush box, place the gun into the box and close the lid. Go to Purge mode. The purge sequence automatically starts.

If the gun flush box is not used, trig- ger the gun (manual or automatic) into a grounded metal pail until the purge sequence is complete.

When done purging, the EasyKey automatically switches to Standby mode.

4.If the system is not completely clean, repeat step 3.

NOTE: If necessary, adjust purge sequence so only one cycle is required.

Purging Mixed Material

There are times when you only want to purge the fluid manifold, such as:

•end of potlife

•breaks in spraying that exceed the potlife

•overnight shutdown

•before servicing the fluid manifold assembly, hose or gun.

Solvent purges the component B (catalyst, right) side of the mix manifold and the inner tube of the integrator. Air purges the component A (resin, left) side and the outer tube of the integrator.

1. Go to Standby mode (remove Mix input).

Trigger the gun to relieve pressure.

If you are using a high pressure gun, engage the trig- ger lock. Remove spray tip and clean tip separately.

If using an electrostatic gun shut off the electrostatics before flushing the gun.

Trigger the gun to relieve pressure. Engage trigger lock.

5.If spray tip was removed, reinstall it.

6.Adjust the solvent supply regulator back to its nor- mal operating pressure.
