Maintenance
4. Check the function of each pulse valve from the
diagnostics screen. Listen for the valve to fire or for
air leaks. Failed pulse valves will fail open draining
the air supply. If this happens, turn off the air
supply and contact RoboVent tech support (1-888-
762-6836) for assistance. (see Figure 19).
5. Ensure the system is off on the HMI (Figure 20).
Then, turn power to the machine completely off at
the disconnect for the unit. This is typically located
near the HMI. You can trace the incoming power
wires back to the disconnect if in doubt. Follow
Lock out Tag out procedures to ensure unit is
de-energized before opening it up. (see Figrue 21).
6. Inspect inside filter cabinet for build-up. Brush
the interior walls pushing the dust down into
the containment area.
DO NOT BRUSH THE
FILTERS.
Brushing the filters will cause unseen
damage severely shortening the filter life and
efficiency.
7. Visually inspect filter door gasket. Any damaged,
torn, or loose gasket will need to be replaced.
(see Figure 22).
8. Close filter door.
9. Open dust tray, record percentage full for
reference to help estimate the frequency needed
for proper maintenance.
10. Visually inspect machine to ensure there are no signs
of leakage, and that the latches and hinges are tight.
11. Confirm air pressure on filter regulator located at rear
of unit is set to 85 psi. Suppled air should be clean
and dry. Oil and/or water in the supplied air will
damage the filters. Check the regulator bowl for any
build up. Blow out any build up found by depressing
the button on the bottom. (see Figure 23).
12. Ensure all doors and access panels are closed and
dust tray is secure.
13. Check floor for any dust that may have spilled,
clean as needed.
