For daily shutdown, use the following steps:
1. Shut off the electrostatic power supply.
2. Open the cabinet door to ground the system and then close the door.
3. Shut off compressed air to the system and reduce the pressure of
fluid input and the coating material supply pump to 0.
4. Trigger the spray device to relieve fluid and compressed air pressure.
5. Open the cabinet door and then clean the male and female couplings
with a compatible cleaning solution.
6. Close the cabinet door.
Use the following steps when changing coating material or cleaning the
system:
1. Turn off the electrostatic power supply and atomizing air.
2. Reduce the fluid input supply pressure to 0.
3. Open the cabinet door. Trigger the spray device into the spray booth
or a grounded waste container to expel any remaining coating
material.
4. Supply cleaning solution to the Iso-Flo system and set the
compressed air pressure to the maximum available (up to 120 psi
or 10.3 bar).
5. Push the door interlock valve. Allow the system pump to fill with
several inches of cleaning solution, as indicated by the rise of the
pump rod. Then, manually trip the upper limit valve to stop the filling.
6. Release the door interlock valve and trigger the spray device into the
spray booth or a grounded waste container. This flushes the system
pump, hose, and spray device.
7. Repeat steps 5 and 6 until the cleaning solution runs clear. Continue
flushing the system until the cleaning solution and any remaining air
have been purged from the system.
8. Push the door interlock valve. Allow the Iso-Flo pump to fill with
several inches of coating material, as indicated by the rise of the
pump rod. Then, manually trip the upper limit valve to stop the filling.
