The default setting of the differential
pres-
sure switch is 120 Pa.
When this value is reached, the control
board sends a maintenance alert message
to the wall controller and the alarm symbol and
filter pictogram
appear on the display (see
the
T-EP
controller chapter).
RECOMMENDED MAINTENANCE
SCHEDULE
Replacing the filters: this depends on the
level of pollution in the air (dust, fumes,
etc.).
The units are fitted with differential pres
-
sure switches that control the pressure
drop of the filter.
Install the new filter and then close the
panel and secure it with the Philips screws.
REPLACING THE FILTERS
(SIDE ACCESS)
Undo the Phillips head screws in the panels
of the filters. Open the filter inspection
hatch and take the filter out sideways.
