Adjusting Material Flow

Flow can be adjusted using the Flow Adjustment Knob. Turn the knob clockwise to
decrease the flow or counterclockwise to increase flow.

Operating the Dispensing Valve

Operation

1.
Plumb up the valve as outlined in the setup procedures.
2.
Apply air pressure by turning on the pressure to the controller.
3.
If necessary, place a new dispense tip onto the valve.
4.
Apply fluid pressure to the valve by turning on the pressure to the material
reservoir.
5.
Cycle the valve to the open position to bleed all air that may have become
trapped when changing the dispense tip. You may need to tip the valve up to 60°
incline and continue cycling the air to remove it all.
5.
Check the fluid connection for leaks. If the valve is leaking or dripping, refer to the
troubleshooting section of this manual.
6.
With the flow adjustment knob backed off counterclockwise 3 or 4 turns and the
dispense tip in place, adjust the air pressure on the fluid (the valve will be in the
open dispense position). Use the flow adjustment knob to reduce the material
flow until the desired flow rate is achieved.

Shutdown

At the end of the day or shift, it is necessary to shut down the Model 485 dispensing
system properly in order to keep material from curing inside the dispensing valve.
1.
Remove the disposable dispense tip from valve and discard.
2.
Relieve fluid pressure on the valve by turning off air pressure at the material
reservoir.
3.
Relieve the air pressure operating the valve by turning off the air pressure to the
controller.
