Maintenance/replacement of the fresh air filter
As a standard feature, the KSCR ECOWATT
®
includes a M5 prefilter on the fresh air. A second F7 filter
can be added (option). The clogging of each filter is controlled by a differential pressure switch with for
-
warding of the information to the controller.
Replacing the filter: (See § "11.10 Replacement parts", page 74)
•
Switch off the electrical supply at the safety swith.
•
Open the hatch or door
•
Remove the prefilter from the slot and then unlock the second filter stage if present.
•
Remove any dust from the compartment close to the filter.
•
Place the new filter(s) in their location(s), and re-lock.
•
Close the door or the door.
•
Restart the unit, the alarm filter is on automatic acknowledgment and should disappear from the
alarm board.
N.B. : At the first start-up, once the installation is completed, it is advised to clean the filter or to replace it.
The pressure switch is attached to the side of the control cabinet.
