Flushing

Flushing
There are times when you only want to flush the fluid manifold, such as:
breaks in spraying
overnight shutdown
end of potlife
In this manual, that procedure is referred to as Fluid Manifold Flushing. You can flush the fluid manifold by connecting either a:
solvent pump to the fluid manifold or
hose and solvent siphon tube to pump A
Other times, you need to flush the entire system:
first time material is loaded into equipment*
color change
•servicing
shutting down equipment for more than 24 hours
putting equipment into storage
* Some Full System Flushing steps are not necessary for
initial flushing, as no material has been loaded into the sys­tem yet.
Fluid Manifold Flushing
Model 248842 Only: Follow the flushing procedure
in the Remote Manifold manual 310797.
Using Solvent Pump
1. Press Stop to turn off proportioner. Follow Pres-
sure Relief Procedure, page 10. Engage trigger
lock. Remove spray tip.
ti1949a
2. Close sampling valves and fluid shutoff valves A and
B.
TI1948A
To flush the entire system, you first follow the Fluid Manifold Flushing procedure, at right, then the Full System Flushing procedure, page 16.
WARNING
Read warnings, pages 5-6.
If your system includes heaters and heated hose, turn them off and allow to cool before flushing. Do not turn on heaters until fluid
lines are clear of solvent.
Use the lowest possible pressure when flush­ing to avoid splashing.
Before color change or shutdown for storage, flush at a higher flow rate and for a longer time.
To only flush fluid manifold, see following pro­cedure.
A circulation setting is available. Consult your distributor. Refer to page 25.

Mix and Integration Tests

Mix and Integration Tests
Use the following tests to check for proper mix and inte­gration.
Butterfly Test
WARNING
Follow Pressure Relief Procedure, page 10, before removing spray tip. Read warnings, page 5.
At low pressure, normal flow rate, and without a spray tip installed, dispense a 1/2” (12.7 mm) bead of material onto foil until multiple changeovers of each pump have occurred. Place a second sheet of foil over the first then peel it back and look for unmixed material (appears mar­ble-like).
Curing Test
Spray a single continuous pattern on foil at typical pres­sure setting, flow rate, and tip size until multiple change­overs of each pump have occurred. Trigger and de-trigger at typical intervals for the application. Do not overlap or cross over your spray pattern.
Check curing at various time intervals, listed on the material data sheet. For example, check for dry to touch by running your finger along the test pattern’s entire length at the time listed on the data sheet.
Appearance Test
Spray material onto metal substrate. Look for variations in color, gloss, or texture that may indicate improperly catalyzed material.

To set the Xtreme Mix to circulate:
5. Depending on the ratio selected, the following will occur:
1.0:1 - Air motor pilot valve A and metering
valve A open to run pump A.
0.0:1 - Air motor pilot valve B and metering
valve B open to run pump B.
To terminate circulation, press Stop .
To begin circulating again, press Start .
To begin spraying, reset to desired ratio and adjust
pump to spray pressure.

Shutdown

Follow this procedure before prolonged shutdown or servicing equipment.
1. Follow Pressure Relief Procedure, page 10.
Engage trigger lock, turn off air regulator, and close main air shutoff valve. Remove spray tip.
1. Decrease the pump air pressure supply to the mini-
mum required to maintain the desired circulation vol­ume.
2. Turn knob to spray .
3. To circulate fluid A, set ratio to 1.0:0, which is the
lowest ratio setting
To circulate fluid B, set ratio to 0.0:1, which is the second lowest ratio setting
See page 13 for instructions on setting ratio.
