9 START-UP AND OPERATION PROCEDURE
9.1
COATING STATION SET-UP
Step 1 -
Press COLLECTOR START pushbutton on the Control Panel.
Check the cartridge filter differential pressure gauge on the Collector
Module. During normal operation, the pressure should remain under
3.5 inches water column. If the reading reaches 3.5 or higher, the
cartridge filters are clogged and should be pulsed. If the differential
pressure gauge still reads 3.5 or higher after pulsing, replace the
cartridge filters.
Step 2 -
Check to see that the Filter Pulser Air Pressure is set to 30 psi (2 bar).
Please refer to the FlexiCoat
®
Powder Application System Manual in
the Appendix of this Manual.
Step 3 -
Add a suitable Electrostatic Fluidized Bed coating powder to the
Coating Bed. The un-fluidized powder depth in the Coating Bed
should measure approximately 1 to 1.5 inches deep.
Step 4 - Turn COATER BED ON/OFF Switch to "ON" position.
NOTE:
The Coater footswitch must be pressed for Steps 5 - 6.
Step 5 -
Turn the High Voltage Control to zero.
Step 6 -
Check to see that the FlexiCoat Bed Air Pressure is set to 45 psi (3
bar). This regulator/gauge is located on the Coating Bed Pneumatic
Control Panel.
Step 7 -
Refer to Section 9.2 for Electrostatic Fluid Bed coating. Refer to
Section 9.3 for Conventional Fluid Bed coating.

ELECTROSTATIC COATING OPERATION
Step 1 -
Adjust the Coating Bed air flowmeter to approximately 30% of the
meter capacity. There should be adequate fluidization of the powder
in the Bed so a cloud forms. Adjust further if required.
NOTE:
The Coater footswitch must be pressed to do this.
Step 2 -
Turn HIGH VOLTAGE ON/OFF Switch to the "ON" position.
Step 3 -
Press the Coater Footswitch and turn the High Voltage adjustment up
to a starting point of 55 kV.
