3. Purge air from the system:Dead-end system: Trigger the spray devices and watch for spitting
as air is purged. Stop when the spray pattern is continuous and
even.
Circulating system: Close the circulation valve (10) and open the
drain valve (11). Watch the flow from the drain rod. When no more
air bubbles are seen, shut the drain valve and slowly open the
circulation valve until the pump is running at the desired number of
cycles per minute. Trigger the spray device(s) to purge air from
them.
NOTE: The more the circulation valve is opened, the more potential
there is for fan pattern collapse or “wink” at the spray device when the
pump changes direction or shifts. Open the circulation valve just
enough to maintain the required fluid temperature and agitation in the
circulation loop.
4. Make sure the air lubricator is delivering one drop every 17−25 strokes.
Adjust the delivery rate as needed.
5. Turn on the fluid heaters (9), if used, and watch the thermometer at the
heater outlet. Circulate coating material through the heater until it is at
desired temperature before spraying parts.
NOTE: Overheating coating materials can cause cavitation in the pump
if the solvents in the coating material boil out in the vacuum created
during the siphon cycle. If this happens, lower the heater thermostat
setting. Refer to Section B5, Troubleshooting for more information.
