e. Go to Mix mode.

11.Adjust the flow rate.

The fluid flow rate shown on the EasyKey Status screen is for either component A or B, depending on which dose valve is open. The fluid supply lines on the screen highlight to show which dose valve is open.

FIG. 102. Status Screen Flow Rate Display

Watch the fluid flow rate displayed on the Status screen while the gun is fully open. Verify that the flow rate of components A and B are within 10% of each other.

If the fluid flow rate is too low: increase air pres- sure to component A and B fluid supplies or increase the regulated fluid pressure.

If the fluid flow rate is too high: reduce the air pressure, close the fluid manifold dose valves fur- ther, or adjust the fluid pressure regulator.

NOTE: Pressure adjustments of each component will vary with fluid viscosity. Start with the same fluid pres- sure for component A and B, then adjust as needed.

NOTE: Do not use the first 4-5 oz. (120-150 cc) of mate- rial as it may not be thoroughly mixed due to alarms while priming the system.

12.Turn on atomizing air to the gun. Check the spray pattern as instructed in your spray gun manual.

NOTE: Do not allow a fluid supply tank to run empty. It is possible for air flow in the supply line to turn gear meters in the same manner as fluid. This can lead to the proportioning of fluid and air that meets the ratio and tol- erance settings of the equipment. This can further result in spraying uncatalyzed or poorly catalyzed material.
