1.Use the socket head screws (4) to secure the dispenser (5) to the

robot mounting plate (2).

2.Connect these connectors to the dispenser (5):

Sheater connector (7)

Ssolenoid valve connector (1)

3.Connect the air line (8) to the dispenser (5).

4.Connect the fluid line (6) to the dispenser (5).

5.Calibrate the micro-adjustment assembly (3), if necessary. Refer to

How to Calibrate the Micro-Adjustment Assembly

in this manual.

After rebuilding the dispenser you must calibrate the micro-adjustment

cap. Turning the micro-adjustment cap clockwise decreases the piston

and needle travel, which decreases coating material flow. Turning the

micro-adjustment cap counterclockwise increases the piston and needle

travel, which increases coating material flow.

If you noted the original setting, set the micro-adjustment to that setting.

Otherwise perform these steps:

1.Turn the micro-adjustment cap to gently seat the needle into the

extension.

2.Open the micro-adjustment cap

-turn counterclockwise.

3.Cycle the dispenser and check for air leaks. Refer to your Select

Coat

system manual for procedures.
