9.5.2 Changing Material/Flushing Fluid System
To change material and flush the Fluid System:
1. If applicable, turn off the heater and allow the fluid to cool for at least fifteen minutes.
2. Reduce fluid air pressure to 7 psi (48 kPa).
! Refer to 6.8.3 Pneumatic Regulators and Gauges for instructions on adjusting
fluid pressure.
3. Open and drain the Fluid Applicator.
! Refer to the manual for your specific Fluid Applicator for instructions.
4. Disconnect the siphoning hose from the container.
5. Adjust the air pressure to allow the pump to stroke slowly.
! The material will drain into the reservoir.
6. When the system is empty, stop the pump by reducing the pump air pressure to zero.
7. Flush the system with solvent as described below:
a. Put the siphoning hose into a container filled with 0.75 liter (1 quart) of solvent.
b. Put the drain hose into the waste container.
c. Start the pump by increasing the pump air pressure. The solvent will purge residual
material out of the system.
d. Close the drain valve.
e. Put the drain hose into the solvent container.
" NOTE If you are using a circulating fluid applicator, such as the SC-104HS or SC-105HS,
perform Steps f and g. Otherwise, skip to Step 8.
f. Open the drain valve and allow the solvent to circulate for one minute.
g. Close the drain valve and open the circulation valve. Allow the solvent to circulate for
another minute.
8. Purge the Fluid Dispensing Applicator several times.
9. Clean the reservoir and fill it with new material.
10. Empty the Fluid System and check the Fluid Filter.
11. Fill the Fluid System with new material.
" NOTE Check that all residual solvent was purged into the waste container by the new material.
