5. Bottle connection / disconnection
Connect a bottle (vial) of vaccine or rinsing fluid (see chapter 9 “Device Cleaning”) to the device by
following these steps:
a. Unscrew the bottle collar (white adaptor on the picture) from the
bottle mount spike.
CAUTION: The spike is very sharp as it has to puncture the stopper of
a vaccine bottle. Please avoid unintended contact with the tip of the
spike.
b. Attach the bottle collar to the bottle as shown on the picture.
c. Pre-puncture the stopper of the vaccine bottle centrally with a
sterile needle to avoid rubber particles being drawn into the spike of
the vaccination device. Place the injector on a solid surface (as shown
on the picture) and push the bottle onto the spike using the pre-
punctured hole.
CAUTION: Without pre-puncturing of the bottle stopper
, rubber
particles may be drawn into the device,
leading to potential
dysfunction by blocked valves and / or nozzle.
d. Connect bottle to device by screwing the collar onto the thread
(clockwise) until it is tight. Please make sure to screw only the white
collar, not the bottle itself. After completion of this step, check if the
bottle sits tightly.
e. Turn the injector back into an upright position. Insert the battery at
the bottom of the handle. This step will activate the device.
To disconnect a bottle from the device, proceed in the reverse order. Always make sure to have the
draw-off spike of the device pointing downwards when connecting or disconnecting a bottle.

8
Otherwise, vaccine will be spilled over the device while a bottle is being connected to or disconnected
from the bottle mount.
If using the tubing collar to connect a larger bottle via tubing, prefill the tubing (!) prior to attaching it
to the tubing collar. When the tube starts to fill, kink the tube just before the end to prevent loss of
vaccine. Then quickly connect the tubing to the adapter.
6. Device Start
Once the vaccine bottle is connected, insert the battery and the device will turn on, showing both the
Boehringer Ingelheim and the FreVAX™ logos on the display. Both logos are shown for 1 second.
If the battery is sufficiently charged:The display will switch initially to the User Menu, unless the
device is in a loaded condition (cylinder filled with vaccine / rinsing fluid) – in which case the display
will show “! Loaded Device ! Press any button” and the LED bars turn red.
By pressing one of the display buttons, the device will rinse once, to
unload the device. The liquid will be sprayed out through the injection
head.
Afterwards, the device will switch to the initial display of the User Menu (see chapter 7).
Before pushing the trigger for the first time, make your settings in the User Menu.
If the battery is too low: The display will show “Low Battery Please
Charge”.

position sensor. Recommended setting is an enabled Position Sensor.
(Disabling is only recommended when using the tubing adapter
supplied with the device and having vaccine delivered via tubing.) For
further details, see chapter 8 “Sensors”.

10
On the second page, the Vial level indicator can be controlled. This
indicator will give an optical warning (via yellow LED bars and warning
sign between piglets on the display) once you have used 90% of the
vaccine inside the connected bottle. When this warning appears, you
have 10% left inside the bottle that is moun
ted to the FreVAX™
device. This allows for a better overview on when to change a bottle
during the vaccination session. To activate the vial level indicator,
choose the size of the bottle / canister you want to mount by pushing
the left display button (50ml, 100ml, 200ml, 500ml, 1000ml, 2000ml,
5000ml, all above 200ml ideally being connected via tubing.)
CAUTION: The vial level indicator is a simple counter that needs to be
set up according to the bottle size mounted to the device. It counts
backwards from the set volume to zero, the current counter reading
is shown in the top center of the display.
On the third page, the Vaccination Style can be selected. Default
vaccination style is “No Delay”, which is for lifting / presenting the
piglets to a second person who is vaccinating them with min. time
lapse between applying the device to the skin of the piglet and the
injection itself. Press and hold the left display button to select the
alternative setting “Delay ?? s”, which offers vaccination of the piglets
by
only one person and leaving the piglets on the floor during
injection. If vaccinating on the floor, a preferred time between skin
contact and injection can be selected, to enable the worker to ensure
proper contact between the device and the piglet before the injection
is released. The device offers settings from 0.1s to 1s by tenths.
On the fourth page, Bluetooth can be controlled. Press the left display
button to disable or enable the Bluetooth antenna.
If using the
FreVAX™ App, enabled Bluetooth is required. If not using the

8. Sensors
The FreVAX™ device is equipped with several sensors to guarantee an optimal vaccination result.
8.1. Position Sensor
This sensor allows for continuous control of the correct holding
position of the device. Once the trigger has been pushed, before
allowing liquid to be drawn into the device the position sensor will
check if it is held upright in order to avoid drawing in air. If the device
is held in the correct angle, which is indicated by the small circle being
inside the big circle, liquid from the attached bottle will be drawn in.
Once the device is fully loaded with liquid, the holding position is no
longer relevant until the trigger is activated again.
Please note: When using the tubing adapter to deliver vaccine, no position sensor reading is needed
because there is no bottle mounted on top of the device. In this case, the position sensor can be
disabled (user menu
 settings  position sensor  off).
8.2. Air Detection Sensor
This sensor measures whether fluid or air is drawn into the device. If
air is drawn in, e.g. by emptying the bottle and not fitting a new one
in time, a warning “Air detected” is shown. Afterwards, only rinsing is
possible, indicated by blue flashing LED bars, until the air exits at the
injection head. This takes a minimum of 3 rinsing cycles, as the liquid
circuit has a volume of a little less than 6 ml and one rinsing cycle
moves a volume of 2 ml. After the rinsing process, you will be able to
vaccinate again (indicated by white flashing LED bars).
8.3. Nozzle Sensor
This sensor enables an extra safety precaution when using the injector. Once the FreVAX™ device is
ready for vaccination (white flashing LED bars), push and hold the trigger. When the device is applied
to the skin of the piglet, the safety sleeve around the injection head will slide back, releasing the
vaccine. If either the trigger is not pushed or the safety sleeve around the injection head does not
slide back, no vaccine will be released. This allows for a high level of user safety.
Furthermore, the nozzle sensor measures if the minimum contact
time between device and piglet for administration of the full dose is
fulfilled. If the injector is released too early, implicating an underdose,
the device will give an optical warning via red flashing LED bars and a
written notification on the display.
9. Vaccination Process
Press the trigger to load the device. The position sensor indicates
the position of the bottle in the holder of the FreVAX™.

12
When the FreVAX™ is held in the right position, the small circle is
inside the big circle and the device begins to load. This function
helps to reduce the risk of drawing air into the system.
At the first run of a new session or after every restart of the device,
the FreVAX™ will be rinsed for three (3) times to flush out remaining
rinsing fluid inside the system and to fill the cylinder with vaccine. No
vaccine will be wasted during this procedure as approximately three
(3) doses of liquid fit into the liquid circuit of the device. The display
will let you know, once the third and last rinsing cycle is completed.
Rinsing is indicated by a blue light LED. If you are changing the battery
and
the changeover between removing the empty battery and
inserting the new one takes less than 5 minutes, the rinsing will be
skipped as vaccine is already in the device.
After three (3) rinsing cycles, press and hold the trigger to load the
device for the first injection. During loading, “Load Device
" is
displayed.
After loading, the device is ready to vaccinate, which is indicated by a
white flashing LED and an illustration of walking piglets
on the
display. At this stage, (1) the first injection cycle can be started, (2)
another rinsing cycle can be carried out or (3) the pen counter or vial
level indicator can be reset.
With option (2) above, another rinsing cycle can be carried out by
pressing one of the display buttons and simultaneously pushing the
trigger. If the dose is set to 1 ml, the device will automatically change
the volume back to 2 ml for rinsing. If the dose is set to 2 ml, rinsing
will be carried out without a change of volume.
The device will automatically switch back to the set dose after the
rinsing cycle, which is indicated by yellow flashing LED bars. This is
only relevant when the dose was set to 1 ml prior to rinsing.
For the option (3) above, to reset the pen counter
or vial level
indicator, press the according display button without simultaneously
pushing the trigger.

13
In option (1), an injection cycle is released once the trigger on the
handle is pressed and held while counter-pressure is generated on
the safety sleeve around the injection head (the two-way security
mechanism) by applying and pressing the injection head onto the skin
of a piglet.
1. Press and hold trigger on the handle of the device.
2. Apply the injection head (A) to the skin of the piglet
perpendicularly (!), add a certain pressure to make the safety
sleeve (B) move backwards and release the injection.
3. During injection, the display will indicate that the device is
currently injecting by showing “Vaccination”. The required
time per injection is 0.1 sec for 1 ml and 0.2 sec for 2 ml.
During this time, make sure that the nozzle of the device stays
pressed onto the skin of the piglet perpendicularly.
4. The device will indicate that the injection was administered
successfully by a green light LED and a notification on the
display. If the device was removed from the skin of the piglet
too early, the device will indicate this by a red light LED. Thus,
the classification into good or bad injection is based on a time
measurement (see point 3 above).
5. After each injection, release the device from the skin of the
piglet to enable the next loading cycle and injection. When
kept in contact with the piglet’s skin after an injection and still
reloading, the device will show “Please rele
ase Nozzle”
before another injection can go into the same piglet by
mistake. Additionally, the LED bars will flash white and red in
alternation.
By keeping the trigger continuously pressed, FreVAX™ automatically prepares itself for the next
vaccination. The next pig can now be vaccinated by pressing the nozzle against its skin.
After administering a vaccination, a small residue of vaccine is visible on the piglet's skin. This is normal
with needle-free intramuscular vaccination and does not affect vaccine efficacy.
10 Device Cleaning
10.1 Rinsing
The cleaning procedure mentioned hereafter should be carried out after each vaccination session.
•Leave the battery attached to the device.
•Disconnect the vaccine bottle (vial).
•To clean the fluid path inside the device (section between bottle attachment and nozzle, shown

Replace the battery when its running time between charges becomes much shorter than usual.
It is recommended that batteries are not recharged before falling below 50% loading capacity.
Never store empty batteries as this could damage them and make them unusable.
Never send/ ship defective batteries to any destination. Instead, please dispose of them correctly.
Charger
Charge the battery using only the charger supplied. Connect the battery to the charger and connect
the charger to an electric socket. When connected correctly, the charging process will start
automatically.
Check the charger regularly for damage, especially the connection cable and the housing. Do not
use damaged battery chargers.
Always grasp the plug, not the cable, when removing the mains plug from the socket.
Faulty electrical installation or too high mains voltage can lead to electric shock. Only connect the
battery charger to an easily accessible socket, so that you can quickly disconnect it from the power
supply in the event of fault.
If you charge the battery improperly, the battery, battery charger and the FreVAX™ device may
be damaged. Charge the battery at an ambient temperature between 0°C and 45°C.
