Disconnect the wiring from the high pressure switch, solenoid valve
BYP and the NTC probe.
2.
Disconnect the pump outlet hose (at the top right).
3. Unscrew the eight hex screws that hold the pump head to the guard.
4.
Remove the gaskets and replace them with new ones (P/N
UAKVG01551).
5. Tighten the eight hex screws so as to secure the pump head to the
guard.
6. Connect the outlet hose to the pump.
7.
Reconnect the pressure switch, solenoid valve and NTC probe
To replace the valves, proceed as follows:

head.

10.4 50 hour oil change warning
The first “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 first started. Therefore when starting the system, make sure a
spare can of oil is available for the first oil change, in accordance with the
procedure described in paragraph “9.3.1 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.
10.5 Maintenance warning and alarm, reset
hour counter
After 1000 hours of operation, humiFog Direct shows a “1000 hour
maintenance” warning, however without shutting down the unit. This
warning reminds the user to check correct system operation. If the pump
manages to reach the rated operating pressure of 70 bars, no action
needs to be taken.
The warning can be easily reset by pressing the “Alarm” button on the
user interface (button at the top left).
The same warning is shown after 2000 operating hours.
After 3000 operating hours, on the other hand, humiFog Direct shows
a “3000 hour maintenance” alarm and the unit shuts down. In this case
is necessary intervene on the unit, changing the oil and replacing the
gaskets and the valves of the pump (as described in paragraph 9.3.1 and
9.3.2).
Will be necessary subsequently reset the alarm in the menu “Control >
screen Da09” 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
Da09. It is recommended, whenever replacing the gaskets and valves, to
also change the oil before resetting the hour counter.
