1.6 FUNCTIONAL DESCRIPTION OF THE DEVICE
1.6.1 INTENDED USE
The HEPA Bulle is a high-performance mobile air purification unit that captures all types of contaminants
in the air: bacteria, viruses, fine particles, pollen, dust. It is used in buildings where air quality control is
desired (schools, businesses, doctor’s offices, nursing homes) to treat the air in canteens, classrooms,
meeting rooms, offices and bedrooms, as well as activity or TV common rooms, among others. It helps
to reduce airborne contamination and is a complementary health measure to other protective actions.
.
1.6.2 OPERATING PRINCIPLES
TheHEPA Bulle sucks in, treats and recirculates the air in the room. It quickly cuts down on environmental
contamination and keeps levels low. The factory-set recycling rate is 5 volumes per hour, as
recommended by the French High Council on Public Health (HCSP) for enclosed areas (14 and 21 May
2021). This can be changed if needed.

SECTION 2 - USE
2.1 OPERATING PRINCIPLES
The HEPA Bulle was programmed to offer a simple, user-friendly interface to users. Using a single
software program, it shows different display modes (with auto mode and manual mode), adapted to
each user’s profile.
2.1.1 USER INTERFACES
2.1.1.1 main screen
Automatic mode activated (see §2.2) Manual mode activated (see §2.2)
The device’s on/off button
Setup button
“Boost” flow settings button
“Silent” flow settings button (automatic mode only)
“Auto” flow settings button (automatic mode only)
Flow settings button (manual mode only)

User manual –HEPA Bulle –ED02_09-August-2021 14 /31
2.2 START-UP
Connect the HEPA Bulle unit to an electrical socket ~ 230 V –50/60 Hz using the 2P+T 10 A power
supply cable provided. The screen turns on.
IMPORTANT: THE ELECTRICAL SUPPLY PLUG MUST COMPLY WITH REGULATORY
TEXTS AND BE PERIODICALLY CHECKED. THE POWER SUPPLY CABLE
MUST BE ACCESSIBLE AT ALL TIMES SO THE PRODUCT CAN BE
UNPLUGGED EASILY, AS NEEDED.
The HEPA Bulle unit loads the operating programme. The initialisation screen appears
(decontamination is not active).
2.2.1 FIRST BOOT
The first time the HEPA Bulle unit boots up, a succession of specific screens appears (called first boot
configuration), where the settings described hereafter must be adjusted. On subsequent start-ups, the
main screen will open directly (see §2.1.1).
NOTE: Confirm the current screen and move to the next screen by pressing the icon. You
can return to the previous screen by pressing the icon.
NOTE: You can reactivate the display of the first boot procedure in the machine settings (see
§3.1).
2.2.1.1 Interface language selection

User manual –HEPA Bulle –ED02_09-August-2021 15 /31
2.2.1.2 Room volume selection
As a reminder, the volume of the room is calculated by multiplying its surface area by its floor to ceiling height.
This height can vary depending on the location, but it is generally 2.5 m.
2.2.1.3 Selection for the number of HEPA Bulle units in the room
If multiple HEPA Bulle units are set up in the same room, their flow in automatic mode and their ARH in
manual mode are automatically calculated and adjusted.
2.2.1.4 Operating mode selection
The HEPA Bulle unit can be used in two different operating modes. airinspace®recommends using AUTO
mode.

User manual –HEPA Bulle –ED02_09-August-2021 16 /31
AUTO mode: Flow settings are automatically
calculated based on room volume and the number of
previously input HEPA Bulle units, as well as the Air
Recycling rate per Hour (ARH).
MANUAL mode: The HEPA Bulle’s flow settings are
chosen by the user from among 5 preset flows. The Air
Recycling rate per Hour (ARH) will appear, for information
purposes, on the main screen.
The default Air Recycling rate per Hour is 5 if
permitted by the HEPA Bulle’s flow. This value can
be raised or lowered by pressing the and
buttons
NOTE: If AUTO mode is selected and the default ARH setting given is under 5, this means the
number of HEPA Bulle units set up in the room is insufficient with respect to the
recommendation of the French High Council on Public Health (HCSP) for enclosed areas (14
and 21 May 2021).

User manual –HEPA Bulle –ED02_09-August-2021 17 /31
2.2.2 SUBSEQUENT START-UPS
The start-up screen varies depending on the choice made when selecting the operating mode (see
§2.2.1.4).
Automatic mode activated Manual mode activated
NOTE: If no buttons are pressed, the screen’s backlighting will dim after 30 seconds.
2.3 CHANGING THE VENTILATION SPEED
2.3.1 AUTOMATIC MODE
When automatic mode is selected, the HEPA Bulle unit is programmed with two ventilation speeds
(Silent and Automatic modes), as well as a Boost function to provide maximum flow.
To select a mode, simply press the corresponding icon:
Silent mode on:
Automatic mode on:
Boost mode on:
Generally speaking and/or when the room is occupied, the device is used in Automatic mode .
Silent mode reduces the noise level by slowing down the device’s flow rate for improved comfort.
Use this mode when there are no or few people in the area of use.
2.3.2 MANUAL MODE
When manual mode is selected, the HEPA Bulle unit is preprogrammed with four ventilation speeds
(200 m3/h, 450 m3/h, 700 m3/h and 1000 m3/h), as well as a Boost function to provide maximum
flow.
To select a speed, simply press the corresponding icon. The active speed appears in green.
Example with 450 m3/h selected:

User manual –HEPA Bulle –ED02_09-August-2021 18 /31
NOTE: During start-up, let the unit run in BOOST mode for at least one hour in the closed
room.
NOTE: The ARH is indicated in the zone and varies depending on the ventilation speed
chosen.
2.4 HANDLING WARNINGS
