Warnings and cautions
Installation
The installation of the air handling unit should only
be carried out by an authorised person. Installa-
tion must be carried out with care and in accor-
dance with the regulations and standards in force
for installation, adjustment and commissioning.
Electrical installation work
The unit must be disconnected from the mains
when carrying out voltage tests, insulation resis-
tance measurements or other operations on the
mains which may cause damage to sensitive elec-
tronic equipment.
Overvoltage protection
Airfi recommends a surge arrester for all Airfi
air handling units. Electrical installations must be
carried out by a professional and in accordance
with local regulations.
Opening the unit
Slide the Airfi cover strip to the side. The hatch is
opened using the screws under the cover strip,
either with a screwdriver or by hand (NB: special
care must be taken when using a screwdriver).
When carrying out maintenance work, always
make sure that the unit is disconnected from
the power supply. Unplug the unit or switch off
the power using the switch inside the unit. NB:
Switching the unit off from inside the unit will cut
off the power supply to the circuit board. There
is still voltage on the primary side of the service
switch. After power has been switched off, the
fans will continue to run for a while. Wait a few
minutes before carrying out any maintenance.
This ensures that the fans have stopped.
Drying laundry
We recommend that you do not connect a tumble
dryer or drying cabinet to the extract air of the
unit.
Condensation water and
condensation
In freezing temperatures, the surface temperature of the
unit can temporarily drop so low that moisture can con-
dense on the surface of the unit in humid conditions. Take
this into account with regard to fixtures near the unit.
Check the condensate drain pipe regularly to ensure that
condensation water can drain freely into the drain.
Commissioning
The unit should only be put into operation after the
dust-generating work on site has been completed. The
duct connectors of the air handling unit must be kept cov-
ered during transport, installation and storage. This keeps
the ducts and the air handling unit clean and allows the
unit to be commissioned without the need for additional
cleaning.

Enclosure The enclosure class of the unit is IP34 when the hatch is closed
Fans Airfi air handling units are equipped with energy-efficient EC
DC fans. The fans can be controlled steplessly.
NB:
On Airfi units, if a fan fails, you can disconnect the electrical
connections from the finger connectors located outside the pro-
tected electrical compartment.

Buzzer alert Gives a beep through the air handling unit housing.
People are spending more and more time indoors, so it is important what kind of indoor air you
breathe. Airfi air handling units and exhaust hoods make the indoor air quality of your property ex-
cellent. Airfi’s continuous ventilation efficiently provides ventilation for your property all year round.
High-quality ventilation provides healthy indoor air in an energy-efficient way, without compromising
living comfort.
In densely built buildings, ventilation is even more important. Ventilation removes moisture from the
building. Ventilation prevents the transfer of moisture into structures and thus the growth of mould and
fungal spores. The heat from the extract air is recovered, increasing energy efficiency.

Controls
Speed #1 Long absence
You can set the air flow rate very low, for example, when you
are away for a long period of time.
Speed #2 Absence / Low load
You can set the air flow rate low and use this speed when your
home is not under much load.
Speed #3 At home / Normal load
It is recommended that the air flow rates in the relevant building
regulations be set for this speed.
Speed #4 Boost / High load
Used, for example, in a situation where the house has a slightly
higher than normal load.
Speed #5 Boost / Maximum load
Used, for example, in a situation where there is a large number
of people in the house, during a party, etc.
With mechanical ventilation, fresh outdoor air is brought into the building through the unit. The air han-
dling unit is equipped with efficient ISO Coarse, 90% + ISO ePM 1 55% filters (former designa-
tion G4+F7), which filter the air coming from the outside to the inside. Remember to replace the filters
regularly, at least every six months. On the extract air side, the heat exchanger is protected against dirt
by ISO Coarse, 90% filters (formerly G4).
The air handling unit heats the filtered supply air before it is released into the room. The incoming
outdoor air is heated primarily by the heat of the air leaving the heat exchanger. Fresh supply air at the
right temperature improves living comfort. Set the supply air temperature slightly lower than the room
temperature. This ensures fresh indoor air and the air coming in mixes more effectively with the air in the
room. The air handling unit must always be on. It only needs to be switched off for maintenance. This
will ensure that the property has adequate ventilation and good living comfort.
Airfi recommends setting the supply air temperature to +17°C. Too high a temperature setting will in-
crease energy consumption and the clean air blown into the room will not mix as well with the room air
compared to if the supply air temperature is 3–4 degrees lower. If low temperature air is to be blown
into the room, the risk of condensation in the duct system must be taken into account. This is why the
factory setting for the minimum supply air temperature is 15°C. Please note that the air handling unit
does not cool the supply air.
Tip!
If the duct system has been carefully insulated against condensa-
tion, even lower temperature air can be blown into the room.

Fans
Heat recovery cell
Airfi units use EC DC fans. Replacing a fan does not require a person with an electrical work licence.
The control and supply connections for the fans are fitted with plugs that do not present a risk of elec-
tric shock. Misuse is also prevented. The Model60/Model100/Model130/Model150 units are
equipped with pin plugs. When replacing a fan, switch off the power at the unit’s service switch.
Airfi air handling units use counter-current heat recovery technology. In the heat exchanger, fresh
air from the outside cannot mix with the air to be extracted. This prevents the transfer of odours and
moisture to the air inside the building. The heat exchanger can be easily removed from the unit and,
if necessary, washed with a mild soap solution and water (do not use a pressure washer). Make sure
that the heat exchanger is dry after washing before putting it back in the unit.
Airfi units also have a “cool recovery” function, which works if the home has, for example, an air-
source heat pump. The heat load of the home is not increased, but if necessary, for example, on a hot
summer’s day, the air entering the house is cooled by air extracted from the inside.
Airfi units also have an enhanced cooling function. The function must be activated by the user, after
which the unit will operate independently at the set values. After activation, the unit monitors tempera-
tures and boosts air volumes as needed depending on conditions. The fan speed during enhanced
cooling can be limited so that, for example, at night the fan does not run at maximum power but at the
maximum speed set by the user.
Airfi units also feature an advanced heat recovery bypass. The heat recovery cell can also be only
partially bypassed, allowing this feature to be used, for example, in spring when the outdoor tempera-
ture rises during the day.
Protective functions
Fault reports /
Buzzer
Airfi units are equipped with an alarm buzzer as standard. The
buzzer will sound to signal an alarm. The buzzer alarm is only
given for critical faults, for example, if a fan is broken or if an R
model unit is installed in an L model duct system.
The unit will continue to operate in a limited manner in the event
of a fault and will return to normal operation once the fault has
been rectified. You can search for a service centre in your area
at www.airfi.fi
Fan
overheat protection
The fans have built-in overheat protection. If the overheat pro-
tection mechanism is tripped, the fan stops. The mechanism is
automatically resettable, meaning that when the temperature
drops, the fan will restart.

Airfi Frost Pro System –
self-learning hoarfrost
protection
(AFPS)
AFPS technology is used to achieve A+ rated annual efficiency
in the Model 60, 100, 130 and 150 air handling units manu-
factured by Airfi Oy. AFPS is standard in all air handling units
manufactured by Airfi Oy. The new AFPS is a self-learning hoar-
frost protection system which guarantees excellent performance
during cold periods.
Airfi Frost Pro System is a Finnish invention, where the heat
exchanger is defrosted only when there is a need for it and the
heat exchanger is guaranteed to work even in prolonged freez-
ing weather.
The energy used to defrost the heat exchanger is taken from the
extract air. This way, the energy provided by the heating resis-
tors is used in the apartment rather than, for example, heating
the exhaust air with the front resistors.
The defrosting function is used optimally, saving energy com-
pared to older solutions. The self-learning capabilities make it
possible to take the individual characteristics of the air handling
unit into account, for example, how dirty the filters and heat
recovery cell are.
Electric heaters Airfi automation is equipped with automatic self-reversing over-
heat protection. If the temperature gets too high, the supply to
the resistor is cut off.
In addition, the unit is equipped with mechanical overheat
protection. If the mechanical overheat protection mechanism is
tripped, the unit’s electric heater cannot be switched on until the
overheat protection activation is acknowledged. When the me-
chanical overheat protection mechanism is tripped, the cause of
the tripping should always be determined.
Fire risk alarm The unit has a built-in fire risk alarm. The fans stop if the tem-
perature of the extract air exceeds +70°C or the temperature
of the supply air exceeds +50°C. The parameters are config-
urable. The fans start to run again when the temperature drops
(factory setting) or after reset.
This function can be disabled by setting the value to 0.
NB: You can select the acknowledgement method from the
Modbus. For example, in the event of a fire risk alarm, you can
choose whether the fans should start automatically or whether a
reset is required.

Installation
NB:
Before installing the unit, make sure that the hand-
edness of the unit matches the ducting of the site.
NB:
The supply air duct must be condensed if indoor
air is cooled through ventilation.
The air handling unit should be installed in a room with a temperature of at least +10°C and where
condensation drainage is possible. The air handling unit should not be installed on the wall opposite
the bedroom or living room wall. When installing, care must be taken to ensure that the electrical and
control cables are placed in an easily accessible location. The unit can be mounted on either a ceiling
or wall bracket. The enclosure class of the air handling unit is IP 34 with the hatch closed.
The air handling unit has an external terminal box where the actuator connections are made. Make
sure that the service hatch is no more than 1.6 m away from the unit.
Installation of ventilation ducts
Wall installation
Ventilation ducts and components are installed according to the HVAC plans. The installation of venti-
lation ducts should be carried out by an authorised installer. Correct and planned insulation prevents
heat loss, moisture condensation and fire spread in ventilation ducts. Even small defects in insulation
reduce sound absorption and pose a risk of condensation and indirect damage. The weight of the
duct system must not put a load on the unit. In order to avoid structure-borne noise, ducts must not be
installed directly against structures. In renovation projects, the insulation of the existing duct system
should always be checked and, if necessary, insulation should be applied.
It is not recommended to install the unit on a wall adjacent to the bedroom. Sound propagation can be
prevented, for example, by using a ceiling mount bracket.
The unit is mounted on the wall using an optional wall mount bracket. If the wall structure consists of
vertical bars and building boards, the fixing point must be reinforced with horizontal bars. This ensures
that the wall can support the weight of the unit. Airfi also recommends that the wall is insulated with
sound-absorbing material or equivalent to prevent sound transmission.
The instructions are general in nature. Install duct insulation according to the site plans.
Accessory
General guidelines on insulation
The supply air duct must always be carefully insulated between the unit’s duct outlet and the silencer,
so that the sound of the fan is not carried into the room. The supply air duct is insulated in a cold room.
»The exhaust air duct is insulated according to country-specific requirements (e.g. fire rating).
»In a warm indoor space, the outdoor air duct and the exhaust air duct are insulated and condensation insulation is also
installed.
»Extract and supply air ducts do not need to be insulated in warm indoor spaces (note the condensation insulation in
cooling).
The ducting through the vapour barrier to the attic must be done carefully. Silencers are placed in the
supply and extract air ducts as close as possible to the unit. Make sure that the duct outputs of the unit
you are installing correspond to the ducting of the site.

11
Remember!
For wall-mounted units, attach vibra-
tion dampers to the back of the unit.
Ceiling installation
The air handling unit can be installed on the ceiling on a ceiling mount bracket. Take into account the
height of the suspended ceiling, if any, when installing the ceiling mount bracket. The ceiling mount
bracket is fixed to the ceiling anchors with M8 threaded rods. The end of the threaded rod must not
exceed the level of the base of the ceiling mount bracket, so that it does not hit the body of the air han-
dling unit. There must be at least four threaded rods per unit. M8 nuts are screwed to the threaded rods
at the appropriate height so that the ceiling mount bracket remains suspended horizontally. You can
use a spirit level to check this. The ceiling mount bracket is locked to the threaded rod with nuts.
The bottom surface of the ceiling mount bracket must be flush with the lower part of the finished ceiling
surface. You can also find the installation instructions for the ceiling mount bracket on our website at
www.airfi.fi.
The same ceiling mount bracket is suitable for both left-handed and right-handed units.
The unit is lifted onto the ceiling mount bracket so that all four locking
mechanisms are in place. Check that the unit is still locked through the
inspection hole, which clearly shows the locked hook mechanism (see
photo).
Vibration dampers are supplied with the wall mount bracket. Install
the vibration dampers on both sides of the lower part of the rear of the
unit. In wall mounting, the installation depth of the unit increases by
6mm.

Floor mounting set
Vapour barrier sealing plate
Condensate removal
The Model 150 is recommended for mounting on a stand. Tilt the unit backwards and attach the
levelling feet supplied in a separate package to the four corner points. There are holes for locating the
stands. When lifting the unit, be careful not to damage the mounting feet. Adjust the unit directly using
the adjusting screws on the feet. If possible, connect the condensate drain hose at the same time.
The Airfi vapour barrier sealing plate facilitates the sealing of the ducts above the unit when the vapour
barrier is penetrated. The duct outlets are located close together and the vapour barrier sealing plate
makes the penetration point tight. Cut a hole smaller than 10–15 mm in the plate’s cellular plastic.
Place the plate on the ceiling at the desired point and fix it to the structure. Vapour barrier plastic is
placed between the structure and the plate and taped tightly.
The same plate is suitable for both left-handed and right-handed units.
Airfi units have a tilted inner floor, which allows the water at the bottom to drain out of the unit quickly.
Condensation water is discharged from the unit through a condensation connection at the bottom of
the unit. The connection has a 1/2" female thread.
Connect the optional Airfi water seal to the connector on the bottom of the unit according to the
installation instructions provided with the water seal. To drain the water produced by the unit, you can
also connect a drain hose or a drain pipe made by an installer to the drain connection, which allows
condensation water to drain away from the bottom of the unit.
Airfi water seal
The Airfi water seal is a silent ball valve water seal designed to re-
move condensation water from the unit. The water seal is suitable for
use with all small air handling units. There should be about 14 cm of
free space under the unit.
Accessory, Model 150
Accessory
The inner diameter of the drain hose or pipe
should be at least 12 mm. The drain hose or pipe
must not be led directly into the sewer. The drain
hose or pipe must not have two water seals or
horizontal drains. The recommended minimum
water seal height is 100 mm. Check that water
can drain out of the bottom of the unit before
starting it up. Pour water into the bottom of the
unit and check that the water is draining out of the
bottom of the unit.

Kitchen bypass
Electricity, control cables and controllers
The extract air from a kitchen exhaust hood is usually connected to an extract air duct. If you want a
more efficient extract air flow through the exhaust hood than normal, a kitchen bypass duct can be
used for Models 60, 100 and 130. The kitchen bypass is plugged and insulated when at the factory.
To enable it, remove the insulation and open the air duct.
In general, the use of a kitchen bypass is recommended to ensure a high level of smoke removal when
using flat exhaust hoods.
The unit is equipped with a grounded 1.6 m plug-in cable for power supply (clearance). The cable
comes from above the unit. The plug acts as the main switch of the unit and should be placed in an
easily accessible location.
Above the unit, there is a junction box where external connections are made (e.g. control hood/con-
trollers). The unit also has an internet cable that connects it to the property’s internet.
Cooling and heating duct radiators are available as an option for all Airfi models.

Controllers
Individual instructions for controllers can be found in a separate document.
Here is an overview of the controllers.
»The air flow rates specified in the building regulations are recommended to be set at speed 3.
»Air handling units and control hoods must always be fitted with an earthed plug.
The Uno control panel has five speeds. The Uno control panel can be flush-mount-
ed into an appliance box or mounted in a surface box. Appliance boxes are not
supplied with the controller.
Sento – hard-wired controller with touch switches. Sento has five speeds.
An appliance box must be installed behind the control panel. Appliance boxes
are not supplied with the controller.
The Mille-Wire controller is hard-wired. This controller is also used as a service
panel. Installation height 1.6 m. An appliance box must be installed behind the
controller. Appliance boxes are not supplied with the controller. The product is
supplied with a mounting bracket.
The Mille controller is an easy-to-use modern controller with a touch screen.

Mille – a Wifi connected control tablet (if the internet switch in the apart-
ment does not have Wi-Fi functionality, choose the Airfi Wire controller),
the Mille Wifi controller works wirelessly, so you will need a USB socket
to connect the controller to the power supply (installation height 1.6 m).
The Mille controller is an easy-to-use modern controller with a touch
screen. If you have connected your Airfi air handling unit to the internet,
the Mille control panel displays up-to-date weather information, air han-
dling unit updates and other information to make your life easier.
An Airfi Oy supplied controller is not necessarily required to control an Airfi air handling unit. You can
buy an app from the app store (Google Play Store or App Store [coming soon]) to control your air
handling unit.
Airfi Cloud
Coming soon
You can connect one or more units to our cloud service, where you can monitor the unit’s activity (sub-
ject to a fee).
Local control from inside the unit without separate controls. Air volume and voltage setting without a
Mille controller or other manual controls is done using the Seven-segment display inside the unit. (see
pages 24–25)
Airfi air handling units have Modbus RTU and TCP/IP bus interfaces as standard. Connection to the
KNX bus requires a separate adapter (accessory: Airfi KNX adapter, product code: 40 000 098).
The Modbus master map is available as a separate document on our website.
The unit is equipped for control-command centre connections. The unit can be controlled from the
control-command centre, e.g. by dual-speed operation or a 0–10 V voltage signal. The supply air
temperature can be controlled by a 0–10 V voltage signal. The speed of the unit can be scanned to
the control-command centre with a 0–10 V voltage signal.
You can control the Airfi air handling unit with the control or booster hoods Pia, Suvi, Ida and Eva.
Electronic hoods synchronise with the controls in real time.

Commissioning
Maintenance
Air handling system settings during commissioning and maintenance can be made using the Mille-
Wire service panel, the Mille Wifi control panel, the Airfi App or locally using the Seven-segment
display (standard inside the air handling unit). The service code for the Mille panel is 12345. At the
time of commissioning, at least the air flow rates must always be adjusted.
The unit’s controller has five speeds. The air flow rates specified in the building regulations are recom-
mended to be set at speed 3 = “at home” position.
At the top of the air handling unit is a plastic cover strip with the Airfi logo. Slide the strip to the right in
the direction of the “open” text to release it and reveal the locking screws of the unit hatch. Open the
locking screws and remove the unit hatch.
Before starting maintenance, disconnect the unit from the power supply by removing the plug from the
socket.
Wait about two minutes before opening the front hatch of the air handling unit. The fans should have
stopped and the potentially hot back-up heating resistor should have cooled down.
The unit can also be disconnected from the power supply by means of a service switch inside the unit.
Turn the service switch to the 0 position before starting any maintenance work.
If necessary, a sizing and selection tool can be found on the Airfi Oy
website.
For unit-specific air flow curves, see page 20.
The unit air flow rates are adjusted to the air flow rates specified by the
ventilation designer. The automation also has the possibility to install
restrictions on the maximum air flow rates (small apartments).
Before you start adjusting the air flow rates, open the unit and make sure there is no debris or objects
that do not belong in the unit. Also check that the filters are clean.
Air flow rates
Opening
Basic air flow control
Tip!
The set values should also be
recorded on the label behind the
unit cover strip.
Remember to record the settings you have adjusted, so that, for example, if a circuit board breaks, the
air flow rate does not need to be readjusted, but the values recorded can be set on the new board. It
would be a good idea to record the set values of the Airfi units on the label behind the cover plate.
New apartments contain humidity due to construction, which is why we recommend keeping the ventila-
tion at least at the air volumes specified in the building regulations. If ventilation is set to too low, mois-
ture can condense on cool surfaces, such as windows.

17
Filter replacement every six months. The filter needs to be replaced more often if there is a lot of dust
in the home or pollutants in the outdoor air. Open the door, remove the old filters from the unit and put
the new filters in place. Always use original filters to ensure proper functioning. Filters are easy to order
from www.airfi.fi/verkkokauppa
Do not use the unit without filters.
The heat recovery cell must be cleaned every three years or more often if necessary. The cell comes
off by pulling. Wash the cell with running water and a mild detergent (e.g. dishwashing liquid). We
recommend cleaning the cell outside the heating season. Make sure the cell is dry before placing it in
the unit.
Clean and inspect every two years.
Removal of fans:
»Disconnect the unit from the mains
»Open the lid
»Remove the heat recovery cell
»Remove the cell strips and the fan flashing
»Disconnect the finger connectors of the fan (NB: the work does not require an electrician)
»Pull the fans out of their mounting rail
»Clean the fan with a soft brush and a vacuum cleaner. NB: the fan blades have balancing strips which must not be
removed.
»Slide the fan back onto the mounting rail, attach the finger connectors, reinstall the flashing and the cell strips
»Reinstall the heat recovery cell and close the lid
Residential area and location have a significant impact on the cleaning intervals of duct systems. It is
recommended that mechanical air handling systems be cleaned every 5–10 years. Remove the fans
from the unit in order to clean it. If necessary, the post heater element can also be removed.

Cleaning the duct system
The condensate drainage from the unit must be checked annually. Pour water into the bottom of the unit
and check that the water flows well through the condensation drain. If you hear a pulsating sound from
the drain, the water seal may be dry. In this case, pour water on the bottom of the unit.
Cleaning the inside of the unit by vacuuming or wiping with a damp cloth as necessary
The water seal can be opened from above and below for cleaning. This way you can clean the drip
pot and condensate ball. After cleaning, pour water on the bottom of the unit to make sure the water
seal works.

The Airfi calculation programme calculates accurate octave-band sound power levels of the air flow in
the duct system and the environment. The programme also calculates the control percentages for both
fans and the SFP value according to the given air flow and duct pressure drop. The programme also
shows the unit’s annual efficiency. This document can also be used as an appendix to an application
for a building licence.
