DANGER
For all users of the device, provide comprehensive instructions on proper operation, the intended
use and the associated risks. Make sure that this manual has been read and understood by all us-
ers of the device. Make sure that this manual is always available to the users of the device.
2.1 Intended use
The device is a nebuliser for indoor applications using exclusively Sanosil disinfectants with a maximum hydro-
gen peroxide content of 7.5%. Its purpose is to transform the disinfecting liquid used into minute particles and
to nebulise them in a room, which then results in uniform disinfection of all uncovered surfaces in the room (3D
disinfection).
The device is intended for use in hospitals, clinics and on public transport, etc. as well as in residential, commer-
cial and industrial areas. This type of disinfection is an additional measure after regular cleaning and disinfection
of room surfaces. In each case, the pre-cleaning protocol is defined by the respective healthcare organisations.
Make sure the surfaces are dry before nebulising to maximise the effect.
ATTENTION
Risk of damage!
This device nebulises chemical substances! The area to be disinfected must only contain items nec-
essary for operation of the device. Objects consisting of sensitive organic materials, especially an-
tiques, paintings and valuable artefacts must be removed.

Operating Manual Q-Jet CT20 © Sanosil 5/32
2.2 Improper use
Always and only use Sanosil disinfectants with a maximum hydrogen peroxide content of 7.5%. The use of any
other disinfectants or accessories that have not been expressly approved by Sanosil Ltd. violates the rules de-
scribed in this manual and may result in serious injury as well as damage to the device. The device is not in-
tended for use as the only disinfection procedure. Instead, it is intended as a supplement to regular cleaning
and disinfection.
DANGER
Risk of explosion! / Risk of injury!
No flammable liquids may be nebulised!
Only Sanosil disinfectants may be nebulised.
2.3 Dangers and warnings
The device must be used in full compliance with this operating and maintenance manual.
•It is strictly forbidden to use the device in an explosive or flammable atmosphere, in dusty areas or in the
presence of people or animals. Prevent people from intentionally or accidentally entering the room during
the fogging process or during the waiting time afterwards.
•There is a risk of injury if unauthorised accessories are used!
•For this reason, only use original accessories from Sanosil Ltd.
•Place the unit on a stable, level, dust-free, non-slip, horizontal surface with a load-bearing capacity suitable
for its weight.
•Always disconnect the device from the power supply before removing the rear panel.
•Carefully read all the information provided on the label of the Sanosil disinfectant.
2.4 Safety instructions for the aerosol and device:
Nebulised disinfectant/aerosol:
•When using the Sanosil Q-Jet and Sanosil disinfectant, high concentrations of hydrogen peroxide are pro-
duced in the air. These can be detrimental or hazardous to health. Only operate the device in rooms that
have been prepared for disinfection and are sealed off. Prevent people or animals from entering rooms
where active aerosol disinfection is present. Prevent aerosols containing peroxide from escaping into parts
of the room with unprotected persons during and for some time after disinfection.
•Once the fogging process using the Sanosil Q-Jet has been completed, the air will be full of fogged Sanosil
disinfectant. DO NOT ENTER the treated room FOR AT LEAST 120 MINUTES AFTER TREATMENT. The wait-
ing time of 120 minutes must be observed. This does not mean, however, that the room can be safely re-
entered after this time. The maximum limit for hydrogen peroxide in the air without any protective equip-
ment is 1 ppm.
•If someone needs to enter the treated room before the end of the waiting time or if the hydrogen perox-
ide content must be measured, the individuals concerned must use personal protective equipment. This
includes a full-face, sealed respirator (filter class ABEK P3) and gloves if necessary.
•The device is intended for use with Sanosil disinfectant (S010 / S015). Do not use any other disinfection
products or liquids.
•ONLY use Sanosil disinfectant to ensure maximum safety and effectiveness. The use of any other cleaning
agent or disinfectant may cause serious injury and environmental damage.
•No one may be permitted to enter rooms while the equipment is in use. Warning signs must be placed at
the entrances.

3. CT20: Technology
3.1 Product description
The CT20 incorporates more than 20 years of experience in aerosol disinfection. Its key feature is the well-
proven compressor/fine mist nozzle technology, which generates a fine, dry disinfection mist. The flow rate can
be adjusted, allowing fog to be produced just 2 metres away from the wall. This presents a major advantage,
which nearly no other device with a similar output can match.
A powerful turbine can, however, be switched on if the CT20 is required for a larger room. Its air jet functions as
a booster and provides the disinfectant droplets with a considerably wider trajectory. What's more, this also en-
sures optimum distribution in the room. Thanks to the 5-litre active-substance tank, a room of up to 600 m3
can be fogged at a dosage of 8 ml/m3.
The device features 2 different operating modes as standard. In Auto mode, the room is automatically flooded
with disinfectant mist up to the air saturation limit. Once this limit is reached, the device automatically switches
off and only continues to operate when the humidity has decreased again. This prevents condensation and con-
sequently ensures that the mist is uniformly distributed in the room. In Expert mode, the desired amount of
disinfectant can be distributed manually via up to 4 cycles of a configurable length as well as 3 customisable
intermediate pauses.
The device is operated using a touchscreen and features a logging function. This makes it possible to save each
disinfection process and export it via a USB stick.

lected and adjusted.
•Connect the device to the mains and actuate the
main switch (D) Let the device start up
•Wait until the General Settings screen appears
•Select "General Settings"
•The "General settings" menu opens
•"Select language" allows you to select the
menu language
•"Date/time set" allows you to set the
date and time

Operating Manual Q-Jet CT20 © Sanosil 11/32
•"Countdown timer set" allows you to set the
countdown timer, i.e. how much time elapses after
the program is started and the fogging
process is started
•The "Minimum contact time" controls how long
the device continues to issue a warning message
after the spraying process has ended
4.2 Disinfection mode
The CT 20 features two different operating modes: "Auto" and "Expert". The difference is how the disinfectant is
delivered into the room.
4.2.1 Auto mode
Auto mode is designed to deliver any amount of disinfectant into the room such that condensation is avoided
as much as possible. Condensation means that the air is saturated with moisture and the liquid starts to settle
on the coldest surfaces. This allows drops to form there. Condensation has an adverse effect on the disinfection
result, since it prevents the disinfectant from being distributed as evenly as possible in the room and from cov-
ering all surfaces evenly as a relatively dry mist.
In addition, condensation on sensitive surfaces can result in unwanted effects. Auto mode prevents condensa-
tion and activates a humidity sensor that constantly measures the relative humidity. As soon as there is a risk of
condensation forming, Auto mode stops the aerosol input and waits until the air humidity has dropped again to
such an extent that the air can absorb more liquid.
The program then continues until the entire desired dose has been supplied to the room without condensation.
Auto mode is ideal for straightforward and uncomplicated maintenance disinfection, e.g. in hotel rooms, gyms,
restaurants and laboratories, etc.
•Press "Run" to treat a new room or to load a saved
room profile.
•Press "Quick Action" to treat a new room

Operating Manual Q-Jet CT20 © Sanosil 12/32
•In "Mode selection" chose an operating mode
•Select "Auto".
•Define the room size in m3
•Select the desired dose per m3
•Select the distance from the nozzle to the walls
and ceiling. (If the distance is specified incorrectly,
the disinfectant may be dosed too quickly and can-
not be distributed in the best possible way.)
•Then go to "Next"
•Check the specifications
•Then tap "Start Cycle" to start the
disinfection process
•Leave the room and wait until the disinfection pro-
gram has finished
4.2.2 Expert mode
Expert mode enables defined, reproducible disinfection results and disinfection cycles that are precisely cus-
tomised for individual rooms. Expert mode thus makes it possible to achieve disinfection results that comply
with the conditions of use set out in DIN EN 17272.
The desired quantity of disinfectant can be distributed manually via up to 4 cycles of a configurable length as
well as 3 customisable intermediate pauses. This enables the best possible disinfection results, but also requires
a certain understanding of aerosol mechanics and how the dosage, cycle and pause length interact depending
on the room to be treated. Otherwise, unwanted condensation may form.

Operating Manual Q-Jet CT20 © Sanosil 13/32
•Press "Run" to select an operating mode:
•Press "Quick Action" to select an operating mode:
•Select "Expert"
•Define the room size in m3 and press "Next" at the
bottom right
•Select the desired number of disinfection cycles

Operating Manual Q-Jet CT20 © Sanosil 14/32
•Select the desired dosage per m3 and cycle. (Make
sure that the desired amount of disinfectant per
cycle is max. 12 ml, for tiled walls of the room
max. 10 ml.)
•Select the pause length between the individual cy-
cles. Just like Auto mode, the pauses ensure that
the air humidity drops after each spraying process,
reducing the risk of condensation and increasing
the contact time with the microorganisms. Pauses
of between 20 and 30 minutes are a good rule of
thumb. Important: two cycles = 1 pause, three cy-
cles = 2 pauses, 4 cycles = 3 pauses
•Select the minimum decay time. This is at least
120 minutes. The decay time is the exposure time
of the aerosol. At the same time, it is also the time
for the peroxide to decompose into
water and oxygen.
(Important: the complete decay of the peroxide
depends on a number of factors and must always
be remeasured in case of any doubt. (Limit value:
1 ppm H2O2 /m3 air.)
•Select the distance from the nozzle to the walls
and ceiling. (If the distance is specified incorrectly,
the disinfectant may be dosed too quickly and
cannot be distributed in the best possible way.)
•Then go to "Next" at the bottom right
•Check all the specifications. Make sure that there
is enough liquid in the tank for the desired pro-
gram. Otherwise, a corresponding
warning field appears
•Start the cycle

Operating Manual Q-Jet CT20 © Sanosil 15/32
•Leave the room and wait until the disinfection
program has finished
4.3 Creating room profiles
You can create different room profiles and edit them under Room Settings. This is particularly useful if the same
rooms with different characteristics will be disinfected with the same device at regular intervals. The idea behind
this is that an expert can define the appropriate settings and then simply leave the actual operation of the de-
vice to instructed assistants.
•Wait until the General Settings screen appears
•Select "Room Settings"
•Enter the password to get access.
Password:= "agent007"
•"Set room" allows you to create the room profile
•"Delete Room" allows you to delete previously
saved room profiles

Operating Manual Q-Jet CT20 © Sanosil 16/32
•Select the Auto or Expert operating mode (for de-
tails on the operating modes, see
section 4.2 .1 or 4.2.2)
•Select the name of the operator, the room name,
the room department (e.g. floor number), the
room cubature and the distance of the nozzle to
walls/ceiling and equipment. (Attention: once a
wall distance has been selected, it must be re-
moved by pressing it again to select
another distance.)
•Optional: If you have selected expert mode, you
must also define the number of spray cycles,
breaks and decay time
(See Screenshots 4.2.2)
•The room is then saved
After programming a room profile, the profile can be activated and started immediately by pressing "OK". Alter-
natively, you can use "Back" to create and save additional room profiles.

•Press "Select saved room profile" to select a previ-
ously saved profile:
•Select a saved room profile. Press the "arrow key"
to browse through stored profiles
•Check all the specifications. Make sure that there
is enough liquid in the tank for the desired pro-
gram. Otherwise, a corresponding warning field
appears
•Start the cycle

4.5 Protocol
Under Protocol, the logged disinfection data can be copied to a USB stick.
•"Protocol" opens the protocol menu
•"Read before the use of USB" opens an infor-
mation menu that provides information on how a
USB stick must be formatted in order to automati-
cally download data for further processing
in Excel format
•"Delete log data deletes stored log data in
the device
•Using USB: format a USB stick (< 8GB) in the
format FAT 32

5. Possible usage profiles for the Q-Jet CT20
A: Overnight disinfection (recommended)
Procedure:
Disinfection procedure in accordance with the manual with a longer, overnight exposure time.
Advantages:
A longer exposure time, maximum disinfection effect, hydrogen peroxide level drops automatically overnight
and only needs to be measured once the following day.
Disadvantages:
The room cannot be used and Sanosil Q-Jet CT 20 is not available overnight.
B: Standard disinfection without additional measures
Procedure:
Disinfection procedure according to instructions with standard waiting time.
Advantages:
Time required: 3-8 hours (depending on room size, humidity and the decomposition time of the hydrogen per-
oxide in the treated room). Sanosil Q-Jet CT20 and the room can be used again sooner.
C: Standard disinfection with forced air exchange
Procedure:
Disinfection procedure in accordance with the manual. After the minimum exposure time, the system does not
wait for the product to be completely decomposed. Instead, a forced ventilation/air exchange system is used to
remove the hydrogen peroxide residues still remaining in the room.
Advantages:
Time required: 3-5 hours (depending on room size and air exchange rate), Sanosil Q-Jet and the room can be
used again sooner.
Disadvantages:
Requires a powerful ventilation system with a separate supply and extract air system and a dedicated control
system for each room.

6. Carrying out aerosol disinfection
6.1 Room preparation
Rooms must be thoroughly prepared in order to ensure that aerosol disinfection is carried out safely and relia-
bly. This must be carried out carefully in accordance with the following instructions.
•Make sure that the room to be disinfected is un-
occupied and not needed or that no one enters it
for a few hours
•Remove all unnecessary equipment and materials,
such as rubbish from the room as best you can
•Thoroughly clean the room. Although the disin-
fectant mist covers all surfaces, it has difficulty
penetrating layers of dust or visible dirt
•Disinfect all previously cleaned sensitive surfaces,
e.g. contact points, etc. using the classic spray-
wipe disinfection method
•Close all doors, windows, hatches, maintenance
openings and connections to other rooms. If nec-
essary, cover them with telescopic
cover plates, etc.
•Switch off the ventilation system in the relevant
room section
•Make sure that fog does not trigger a false alarm
in your fire alarm system
•If necessary, cover individual detectors in the
room to be disinfected. Important: never switch
off the entire fire alarm system
