INTENDED USE
PRINCIPLE OF WORK
The basis of the technical solution for recuperation ventilation is the countercurrent, with a
continuous thermal cycle, a copper heat exchanger, which makes it possible to form two
different-directed airfl ows in the volume of one cylinder (Fig. 1).
Warm exhaust air that is removed from the room, passing through a copper heat exchanger
transmits its warmth to the counter stream of fresh air from the outside.
The system allows recover heat, which contributes to increasing the overall recuprration rate
and allows maintain the optimum humidity mode in the room. Taking into account that air
streams are separated and regulated at levels “infl ow” – “exhaust”», there is no mixing of
different-directional air fl ows.
High velocity of the fl ow with suffi cient heat transfer effi ciency ensures removal of up to
90% moisture in a dispersed state, preventing its condensation and freezing of the heat
exchanger at low ambient temperatures.
DESCRIPTION OF THE DEVICE
Ventilation units “PRANA-150”, “PRANA-200C”, “PRANA-200G” are intended for creation and
maintenance of healthy microclimate in premises.
These systems are recommended for use in residential and public facilities (apartments,
houses, offi ce premises, educational establishments, kindergartens, etc.).
PRANA-150 and PRANA-200 belong to the category of innovative and reliable products
aimed at creating and maintaining a healthy microclimate in premises of various functional
purposes.
High energy effi ciency and signifi cant air exchange capabilities make it possible to apply
these ventilation units for organizing domestic ventilation.
Technologically, the system is a monoblock with high-effi ciency counter-current copper
recuperator ready to use in accordance with the design and assembly tasks and conditions.

ADDITIONAL FUNCTIONS
“Mini heating up” function
For additional comfort in equipping residential premises with ventilation systems PRANA
of residential-and-public and semi-industrial series, the function of air “Mini heating up” is
provided for. It can be switched on by pressing the “Mini heating up” button on the remote
control or in a mobile application (see the remote control manual included in the list of
standard equipment).
After having activated the function of “Mini heating up”, the temperature of the infl ow air
increases by 3-5 ºC.
When the motors are switched off and the cover of the recuperator is open, this function
additionally plays the role of an air heat curtain.
WARNING! DO NOT SWITCH ON “Mini heating up”, if the outside air temperature is +20 ºС and
above!
Function “Winter Mode”
Function “Winter Mode” is intended to prevent the icing of condensate drainage during the
cold season or to freeze it if icing has occurred.
WARNING! To avoid icing and to ensure the system operates correctly at the minus
temperature from the outside - the use of the Winter Mode is mandatory.

In mode «AUTO» after engine shutdown, «Winter mode» will work for 30 minutes to prevent
icing in the system, which may result in reduced effi ciency or condensate drainage
complications.
Preheating element (additional option)
Recuperators that will be used in rooms with excessive humidity in the cold climate are
recommended to be equipped with an additional heating element.
Passive mode
The operating mode of the ventilation system with the open lid of the recuperator and
switched off motors. It lies in the movement of uncontrolled airfl ows through the recuperator
due to the difference in pressure and temperature inside and outside the premises. It is
allowed to use, when the difference between outside and inside temperatures is no more
than 5 o C.
Defrosting
WARNING! In the cold season, the improper operation of the recuperator is likely to freeze it!
When freezing, it is necessary to activate function «mini-heating» with engine switched off
for at least 60 minutes, and let it freeze, then turn on the recuperator to the required mode.

Bidirectional ventilation unit with heat recovery “PRANA” is a monoblock ready for use in
accordance with design and assembly tasks and conditions.
The system is mounted in a hole of the appropriate diameter in the upper part of the wall
adjoining the outside, at a distance of no less than 100-150 mm from the ceiling or walls. The
through hole should be a slope of 3-5 degrees towards the outside. The operating module of
the ventilation unit is mounted in the hole using a seal (Fig. 4).
The length of the working module should correspond to the thickness of the wall in which
the installation will be carried out. In order to ensure the normal operation of the system, it
is necessary that its body facing the the outside extends beyond the wall by 1-2 cm to the
beginning of the air intake (Fig. 4).

CONNECTING TO THE ELECTRICAL SUPPLY NETWORK
Connecting the recuperator to the electrical supply network, controlling the system from the
remote control.
Disconnect the power supply to the electrical system to which the ventilation system will be
connected.
Warning! Ensure that the electric power supply is really switched off!
The connection of the ventilation unit to the electrical supply network is done using an electric
cable, which is laid from the working module (standard equipment).
In the event that the electrical system is not laid to the mounting hole, the electric cable
from the recuperator should be connected to the electrical supply network in the distribution
box according to the diagram in Fig. 6: You must connect the contact terminals 1 and 2 in
parallel, or install in the cable an electrical connector that meets the above parameters for
quick connecting and disconnecting electrical appliances. Electrical connectors are not
included in the list of the standard equipment.
If the cable of the electrical supply network of the building has been laid to the mounting
hole, then the power supply to the working module cable is carried out in the immediate
vicinity of the body of the recuperator. Shorten the electric cable from the recuperator to a
length that is convenient for electrical connection.
All electrical cables used in the installation should have the cross-section of 0.5-0.75 mm².
The operation of the system is controlled using a remote control or mobile application that
controls the operation of the fans installed in the body of the ventilation system (it turns on,
regulates and turns off).
The PRANA 150 / 200G / 200C recuperators are adapted to an existing electrical network in
an automatic mode, without the use of software. This signifi cantly reduces the noise indicators
of the equipment and allows ensure the the noise characteristics of the ventilation system
declared in the technical passport. The control board is connected to the recuperator unit
in accordance with Fig. 7. The colour of the wire should correspond to the terminal on the
board.
Warning! After having connected the ventilation system to the electricity supply network, it
is necessary:
1. to supply electrical power to the device.
2. to check the operation of the fans in different operating modes, using control units.
