SPECIFIC RECOMMENDATIONS:
• If you change the settings of the
extract fan you have to handle the
potentiometers in the printed cir-
cuit board. These potentiometers
are fragile and must be handled
with care.
• Do not change the setting of the hu-
midity sensor out of the room whe-
re the fan will be installed.
• If the humidity is always above 90%
RH, the fan will always run at full
speed.
• If the humidity in the room is always
less than 60%, the fan will only ope-
rate on trickle speed when running
in automatic operation.
If the fan never runs on boost:
• The setting of the humidity sensor
has been set to maximum. Change
the setting.
• The level of humidity in the room is
below 60% RH.
If the fan always runs at boost:
• The setting of the humidity sen-
sor has been set to the minimum.
Change the setting.
• The level of humidity in the room is
above 90% RH.
ECO DMEV HTP
ECO dMEV version similar to H model,
fi tted with a manual pull cord to oper-
ate the boost when the humidity level
is below the set point (fi g.6).
When switching the pull cord off, the
fan will continue to operate on boost
for the time set by the timer then will
revert to trickle speed, unless the hu-
midity level exceeds the set point.
MAINTENANCE
IMPORTANT: disconnect from the
mains supply before carrying out any
maintenance.
The ECO dMEV extract fan is supplied
with a plastic fi lter.
Performance depends on cleaning
frequency and thus we recommend
cleaning, minimum every two months,
in accordance with fi g 1a.
The ECO dMEV extract fan must al-
ways be operated with the fi lter fi tted.
Using the extract fan without the fi l-
ter invalidates the warranty.
The external surface of the fan only
requires periodical cleaning using a
cloth lightly impregnated with a soft
detergent.
