• Turn off the main switch whenever a malfunction is detected or when cleaning.
• For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance with the wiring regulations, to provide a full
disconnection under overvoltage category III conditions (contact opening distance equal to or greater than 3mm).
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return into the room in compliance with existing regulations in order to ensure proper device operation.
• If the environment in which the product is installed also houses a fuel-operating device (water heater, methane stove etc., that is not a
"sealed chamber" type), it is essential to ensure adequate air intake, to ensure good combustion and proper equipment operation.
• Install the product so that the impeller is not accessible from the air outlet side as verified by contact with the Test Finger (test probe "B" of
the norm EN61032) in compliance with the current safety regulations.
• Ceiling installation
In order to guarantee the IPX4 degree of protection against moisture in case of ceiling installation, use the appropriate ceiling mount kit,
which is not included. Use only the rear entry hole for supply cables. If there is a possibility of condensation along the air discharge duct,
provide a drainage system to prevent condensation from discharging into the environment through the fan.
Attention: do not mount the product on the ceiling without this kit.
• Window installation
In case of window installation it is necessary to use the appropriate window kit, which is not included.
Attention: do not mount the product on the window without this kit.
VERSION
WITH HUMIDISTAT/TIMER
The fan is equipped with a humidity sensor, whose threshold is adjustable from 50% to 95% Relative Humidity via dedicated trimmer, and with
a timer which is adjustable from 0 to approx. 30 minutes via dedicated trimmer (fig. 15E).
The fan runs continuously at selected trickle speed (set by the jumper switch combination - see figure 16), increases its speed in case the
percentage of Relative Humidity exceeds the settable threshold, and can anyway be boosted with a dedicated ON/OFF switch (or PIR, CO2...
sensor) or with a light switch (fig. 14E). Trickle speed can be set to off.
To deactivate the humidistat function, turn the trimmer HY completely clockwise.
Automatic humidistat operation: when the percentage of Relative Humidity exceeds the settable threshold, fan speed automatically increases
to "comfort boost" speed, which is intermediate between the selected trickle speed and the boost speed. When the percentage of Relative
Humidity goes below the threshold, the fan continues to function at "comfort boost" speed for a factory set period of time then returns to
selected trickle speed.
Operation with external switch: connected according to the diagram in figure 14E. When the external switch is turned on, the fan is boosted.
After the external switch is turned off, the fan continues to run at boost speed for a settable period of time, then it returns to selected trickle
speed (or to "comfort boost" speed in case automatic humidistat operation is on). The front cover LED indicates when the external switch is
on. The over-run timer function is activated only if the external switch has been on for at least 60 seconds.
