WARNINGS AND SAFETY MEASURES
• This device may be used by children from the age of 8 years, as well as
by physically or sensory disabled or mentally challenged persons or people
with lack of experience and knowledge, provided that they are supervised
or instructed about the safe operation of the device and understand the
dangers involved. Do not allow children to play with the device. Maintenance
should not be performed by children.
• During the operation of the device, the fan rotates inside it. Avoid
getting foreign objects inside the device during operation. This may result
in injury.
• A user without proper qualifications must not install, move, disassemble,
modify or repair the recuperator themselves.
• Do not block the supply and exhaust channels, as this will reduce the
quality indicators of the recuperator and may lead to system failure.
• Do not place heating equipment in the way of the air intake by appliance.
Products of incomplete combustion can lead to accident.
• If the outdoor air temperature is +20°С and above, do not switch on the
functions of «Mini heating», «Winter mode», «Defrost».
• Do not use the device at a temperature of +50 °C and above, near open
flames, in places exposed to smoke or where it may come into contact with
organic solvents. This may cause a fire.
• Make sure that the outdoor air intake is located so that smoke or other
harmful gases do not enter it. If the intake air is polluted, the quantitative
and qualitative indicator of oxygen in the room may decrease.
• Before use it is necessary to make sure that the mechanical and electric
installation norms applied in the country where the installation is performed
are observed.
• In the event of damage to the recuperator, immediately switch off
the system with the circuit breaker or unplug it. Continued use of the

5
recuperator may result in smoke, fire, electric shock or injury. For repairs,
contact the service center of the manufacturer or dealer in your area.
• We recommend that you use original PRANA filters for the recuperator
to work properly and to prevent damage to the ventilation system.
• Before switching on it is necessary to open an air intake, accordingly,
after use to close it (if there is no need to use a passive mode of operation).
When using the system with the air intake closed, it can damage the
recuperator.
• In order to avoid icing and ensure the correct operation of the system
at ambient temperatures below + 4 °C, the use of functions «Winter mode»
and «Miniheating» is mandatory.
• In case of plugging in with the power plug, do not pull on the cord while
trying to unplug it. The power plug must be firmly plugged into the outlet.
Otherwise, it may result in electric shock.
• Avoid hitting and damage to the system (recuperator).
• Do not twist, damage, or modify the power supply cord. Do not expose
it to heat or place heavy objects on it. These actions may result in fire or
electric shock.
• If the power cord is damaged, in order to avoid danger it must be
replaced in a service center, by a manufacturer or a qualified person.
• Sensors installed in PRANA ventilation systems are not a metrologically
accurate means of measurement. The sensors are designed to monitor
changes in air quality and temperature conditions for proper control of the
system in automatic modes.
• The appliance must be de-energized before carrying out any operations
of maintenance service (unplug the appliance or turn off the main power
switch and wait for the fans to come to a complete stop).
• To prevent back draft in rooms where fireplaces, gasfired water heaters
and other equipment that creates or uses different mixtures of gases
operate, the use of «Separate control» mode is not allowed.

DEVICE AND SOFTWARE UPDATE
Some content may differ from your device depending on the model,
region or software version, and may change without prior notice.
The PRANA recuperator is a device that is controlled from a smartphone,
so some functions, performance and efficiency may change.
Some points in this guide may not be relevant if you update the software.
You can always read the updated instructions at the link:
(prana.help/b22).
You can also ask for help from the seller at the contacts listed in the
warranty card (warranty card is in the technical passport of the product).
PRANA is not responsible if the client has not been able to use the «PRANA
ONLINE» services on their devices and/or uses them incorrectly.
This is due to the large number of manufacturers of multimedia devices
for which the adaptation of services may be performed after some time.

details about this mode of operation are described in the «Separate control
mode» section.

18
Passive mode is the operation of the recuperator with the cover open and
the engines off.
It is based on the movement of uncontrolled air flows through the
recuperator. This is due to the difference in pressure and temperature inside
and outside of the room.
Allowed for use when the difference between outdoor and indoor
temperatures is not more than 5°C.
PASSIVE OPERATION MODE
DEFROST FUNCTION
MANUAL CONTROL MODE
In the cold period, with improper operation of the recuperator there is
a risk of icing of the heat exchanger, which leads to a significant efficiency
reductions, accumulation of condensate in the system and icing of the engines.
In the event of icing it is necessary:
1. Turn on the recuperator;
2. Turn off the supply and exhaust;
3. Close the front cover;
4. Enable the «Mini-heating» function;
5. Wait 60 minutes for it to defrost.
Then switch on the recuperator in the required operating mode.
If there are no improvements, this algorithm must be repeated.
Manual mode is used as the default system mode. System performance
changes in increments of 10%.
Switching speed modes can be done with +/- buttons on the remote
control or in the mobile application.
You can switch the system for simultaneous flow control by pressing
2x ***** on the remote control or ***** in the mobile application.

19
NIGHT MODE
«1/10» on the info panel - the system works in the
«Night» mode.
The minimum and quietest mode of operation of the system, which is
designed to work at night.
Activated with the *** button on the remote control or the *** button in
the mobile application.
The function allows you to separately control the flow of supply and
exhaust air.
Volumes of supply and exhaust air can be seen in the mobile application
and info panel (values from 1 to 10).
In order to control the air flow with the remote control, press the *****
button for the supply or the ***** button for the exhaust, and then set the
required volume of air with +/- buttons.
In order to control the air flow from the mobile application, press the
***** button and then set the required supply and exhaust volume using
+/- buttons, the supply values will be at the top and the exhaust values at
the bottom.
SEPARATE CONTROL MODE
VENTILATION MODE
«10/10» on the info panel - the system works in the «Ventilation» mode.
The maximum operation mode of the ventilation system. The «Ventilation»
mode is activated by the *** button on the remote control or the *** button
in the mobile application.
ADJUSTMENT OF THE INDICATION BRIGHTNESS
In order to ensure the comfort of operation of the system in the dark, we
have provided 6 levels of display brightness.
The brightness of the display can be adjusted with the ** * button on the
remote control or **** in the mobile application.

20
For additional comfort of the operation, the date and time function is
optionally available in recuperators. The function is activated via an additional
menu.
The system (recuperator) receives the date and time from your smartphone
during synchronization.
When disconnecting the system from the power supply network,
synchronization should be repeated.
If you remain the date or time active, it will be displayed until you switch
the information display.
