WARNING AND SAFETY MEASURES
• The ventilating system can be used by children aged 8
years and older and by people with physical, sensory, mental
disabilities or lack of experience and knowledge if they are
supervised or instructed to operate the unit in a safe manner
and understand the hazards involved in its use. Do not allow
children to play with the ventilation system.
Installation, cleaning, and maintenance should not be
performed by children.
• The fan inside the device rotates during operation. Avoid
putting foreign objects inside the device during operation.
Doing so may result in personal injury.
• The unqualified user must not install, move, dismantle,
modify or repair the ventilation system himself.
• Begore the use make sure that the installation complies
with the mechanical and electrical regulations which are in
force in the country where the installation was carried out.
• Do not install heating equipment for air intake by a
ventilation system.
Incomplete combustion products can cause an accident.
• Installation by unqualified people can result in poor
performance, damage to the ventilation system, and
accidents.
• If the ventilation system is used in the same room as
other ventilation systems in operation, the performance of
the unit may differ from the stated performance.

5
• The presence of excessive wind pickup can affect the
performance of the ventilation system.
• Avoid damaging of the ventilation system.
• Warnings and precautions when installing the PRANA
ventilation system are described in the installation manual.
• If the heating elements from a third party supplier
are connected to the PRANA system control unit, the
manufacturer is not responsible for the proper operation of
both devices.
The heating elements, which may (optionally) be supplied
by the manufacturer, undergo a technical preparation stage
for proper operation.
• The air conveyed must not contain combustible or
explosive mixtures, chemically active vapors, sticky
substances, fibrous materials, coarse dust, soot, grease or
media that promote the formation of harmful substances
(poison, dust, pathogens).
• The unqualified user must not install, move, dismantle,
modify or repair the ventilation system himself.
• Before installation, make sure that there is no mechanical
damage to the structure and fasteners.
• If damage occurs, immediately de-energize the system
with a circuit breaker.Continued use may cause smoke, fire,
electric shock or injury.

6
Contact the manufacturer's service center or dealer in
your area for repair.
• It is not allowed to mount the connection heater with
the box downwards (danger of condensation and short-
circuiting of the wiring).
• Do not twist, damage or change the power cord. Do not
expose it to heat or place heavy objects on it. Doing so may
cause a fire or an electric shock.
• Do not block the intake or exhaust air passages as this
will reduce the performance of the system and could result
in stopping and/or smoke, fire, electric shock or injury.
• The recuperator is connected by means of insulated
strong conductors (cables, wires) with a cross-section of
0.5-0.75mm2. All wiring must be installed by a qualified
electrician in accordance with the Electrical Installations
Code.
• Heaters must be installed in a duct of similar diameter
(size). The minimum allowable distance between heater and
recuperator is at least 0.5 m of metal duct.
• The duct heaters are designed for a minimum airflow
rate of 1.5 m/s and a maximum exhaust air operating
temperature of 40 °C.
• Before performing any maintenance operations, de-
energize the unit (turn off the main power switch and wait
for the fans to of the fans to stop completely).
• Heaters cannot be insulated with thermal insulation
materials.

7
• The manufacturer is not responsible for the installation
that is carried out by an unqualified specialist (or group of
specialists) and all subsequent consequences connected
with it.
Incorrect installation will invalidate the warranty.
• The air ducts must be equipped with grills or other device
preventing free access to the fans.
• To avoid reverse draught in rooms where fireplaces,
gas heaters and other equipment producing or different
gas mixtures are in operation, the "Separate control" mode
must not be used.
