INTRODUCTION
This user's manual includes technical
description operation, installation
and mounting guidelines, technical
data for the heat recovery ventilator
VT-501.
USE
The ventilator is designed to arrange
permanent controllable air exchange
in apartments, villas, hotels, cafes
and other domestic and public
buildings.The ventilator is equipped
with a ceramic heat exchanger that
enables supply of fresh air and
extract air with heat energy recovery
The ventilator is designed for
through-the-wall mounting. The
telescopic ventilator design enables
its installation in the walls from 250
mm to 400mm thickness for the
ventilator VT-501.
The ventilator is rated for continuous
operation always connected to
power mains.
Transported air must not contain any
flammable or explosive mixtures,
evaporation of chemicals, coarse
dust, soot and oil particles, sticky
substances, fibrous materials,
pathogens or any other harmful
substances.

application with the ambient
temperature ranging from -20°C
(-4°F) to +50°C(+122°F) and relative
humidity up to 80%.
The ventilator is classified as a class I
electric appliance.
Ingress Protection (IP) rating from
solid objects and liquids IP 24.
The ventilator design is regularly
improved, so some models may
slightly differ from those ones
described in this manual.

DESIGN AND OPERATING
The ventilator consists of the
telescopic air duct with adjustable
length regulated by position of the
inner air duct inside the outer air duct,
the ventilation unit and the ventilation
hood.
Two filters and the ceramic core are
located inside the inner duct
The filters are designed to purify
supply air and prevent foreign object
ingress to the heat exchanger and the
fan.
The ceramic heat exchanger extract
air heat energy to warm up or cool
down supply airflow.
The heat exchanger is equipped with
a pull cord inside to facilitate its
withdrawal from the ventilator. The
heat exchanger is installed on an
insulation material used as a sealant
as well.
The ventilator must be installed on
inner side of the wall.
The ventilation hood must be
installed on outer side of the wall to
prevent ingress of water and other
objects to the ventilator.

READ THE USER’S MANUAL
PRIOR TO MOUNTING THE
VENTILATOR
CAUTION!
THE VENTILATOR MUST NOT BE
INSTALLED IN SITES WHERE THE AIR
DUCT MAY BE CLOGGED BY
THE BLINDS, CURTAINS, DRAPES, ETC, TO
PREVENT THE ROOM DUST DEPOSITION
AND ACCUMULATION. ALSO, CURTAINS
MIGHT OBSTRUCT NORMAL AIRFLOW IN
THE ROOM, THUS RENDERING
VENTILATOR OPERATION NOT EFFICIENT.
The ventilator has three ventilation
modes:
Fresh Air Mode the ventilator supplies
fresh air
Exhaust Mode the ventilator operates
in exhaust mode
Cycle Mode the ventilator operates in
reversible mode with heat and
humidity recovery
In cycle mode the ventilator operates
in two cycles, 65 seconds each.
Cycle I. Warm stale air is extracted
from the room. As it flows through the
heat exchanger, it heat and moisturizes
the exchanger, transferring up to 90% .
In 65 seconds as the ceramic
exchanger gets warmed the ventilator
is switched to supply mode.
Cycle II. Fresh intake air from outside
flows through the ceramic exchanger
and absorbs moisture and heats up to
the room temperature. In 65 seconds
as the ceramic regenerator gets cooled
down, the ventilator is switched into
extract mode and the cycle is renewed.
