• I f 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.
• I nstall 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.
• C eiling 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.
• W indow 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.
INTROdUCTION
Quantum AX (fig. 1) is a decentralised mechanical ventilation unit designed to ensure air
extraction in small/medium-sized rooms.
Suitable for air discharge directly to the outside or in the presence of short ducted system.
Wall, ceiling or window installation (fig. 2).

VERSIONS
BASIC
The fan runs continuously at selected trickle speed (set by the jumper switch combination
fig. 16) and can be boosted with a dedicated ON/OFF switch (or PIR, CO2... sensor) or
with a light switch (fig. 14A). Trickle speed can be set to off (fig. 16).

PULL CORD
The fan can be boosted with a dedicated ON/OFF switch (or PIR, CO2... sensor) or with
the integrated pull cord (fig. 14C).
WITH OVER-RUN TIMER
The fan is provided with over-run timer, adjustable from 0 to approx. 30 minutes via
trimmer (fig. 15B).
The fan runs continuously at selected trickle speed (set by the jumper switch combination
fig. 16) and can be boosted with a dedicated ON/OFF switch (or PIR, CO2... sensor) or
with a light switch (fig. 14B). Trickle speed can be set to off.
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. The over-run timer function is activated only if the
external switch has been on for at least 60 seconds.
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
fig. 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 fig. 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.
Operation with pull cord switch (HTPC version): connected according to the diagram
fig. 14D. When the pull cord switch is turned on, the fan is boosted. After the pull cord
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 pull cord switch is
on. The over-run timer function is activated only if the pull cord switch has been on for
at least 60 seconds.
