Empty The Day Tank - Graco Aerobotix RC50 Instructions Manual

Maintenance

Empty the Day Tank

See the day tank capacity in the table at the begin-
ning of the Settings section on page 45. To avoid a
potential mess, always prepare to collect up to the
full capacity.
1. Turn the main power handle to the off position and
lockout.
2. Close tank air supply valve (MK).
3. Depressurize day tank to approximately 5 psi.
4. Place container to catch tank fluid.
5. Open the tank outlet valve (MJ) and the tank drain
valve (ML) and empty tank into the container.
6. Be careful as the last of the tank fluid is released,
there will be a semi-uncontrolled spitting of material
from the 5 psi charge.
7. Close the tank supply valve and replace the drain
plug.
If no further maintenance is anticipated, leave the 5 psi
charge of dry air on the tank. Otherwise vent the charge
to zero pressure.
NOTICE
If the machine will be left with zero pressure for more
than 30 minutes, the day tanks must be emptied and
thoroughly flushed to avoid chemical crystallization
and machine damage. See Long-Term Shutdown on
page 44.
