13.5 50 hour oil change warning
The fi rst “oil change required” maintenance warning is shown after
50 operating hours: this indicates that the oil needs to be changed
immediately. This warning is typically displayed a few days after the
systems is fi rst started. Therefore when starting the system, make sure a
spare can of oil is available for the fi rst oil change, in accordance with the
procedure described in paragraph "Oil change".
The warning can be easily reset by pressing the “Alarm” button on the
user interface (button at the top left).
For practical reasons, the warning can also be reset after 40 operating
hours, entering the “control menu > screen Da10”. The warning cannot be
reset before 40 operating hours.
13.6 Notifi cation, maintenance warning,
reset hour counter
After 1000 of operation, humiFog direct generates a non-blocking "visual
hydraulic check" notifi cation. This is a warning that tells the user to check
correct operation of the system. If the pump can reach the nominal
operating pressure of 70 bars, no action needs to be taken.
The notifi cation can be easily reset by pressing the "alarm" button on the
user interface (top left button).
The same occurs after 2000 hours of operation.
After 3000 hours of operation, instead, humiFog direct generates a non-
blocking "request for oil change and parts replacement" alarm. In this
case, the machine must be serviced by changing the oil and replacing
the pump gaskets and valves ("Changing the oil" and "Changing the
gaskets and valves").
Will be necessary subsequently reset the alarm in the menu “Control >
screen Da10” and press subsequently the “Alarm” button of the display.
If for some reason the gaskets and valves need to be replaced before
3000 operating hours, the hour counter needs to be reset on screen
Da10. It is recommended, whenever replacing the gaskets and valves, to
also change the oil before resetting the hour counter.
