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.

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.

VENTILATOR MOUNTING
Operation Instruction for the user and the qualified installer
11
1. Prepare a round hole through in the
wall. The hole size is shown below.
3. Install a telescopic air duct inside
the wall. The telescopic air duct end
must protrude to the distance A
stated below：
4. Connect the mounting plate
following the wiring diagram, page
15. Prepare four fastening holes and
fix the mounting plate on the wall
with four 4x40 screws and 6x40
dowels (included in the delivery set).
Align the telescopic air duct to the
mounting plate and fill the gaps
between the wall and the telescopic
air duct with a mounting foam. The
telescopic air duct must not
protrude from the mounting plate
surface.
2. After preparing a through hole cut
out a 25 mm (r) deep recess for laying
of the cables and the contact sockets
connected to the mounting plate.
The recommended recess profile is
shown in the drawing below.

MAINTENANCE
1.Fan maintenance (once per year).
Operation Instruction for the user and the qualified installer
15
DISCONNECT THE
VENTILATOR FROM POWER
SUPPLY PRIOR TO ANY
MAINTENCE OPERATIONS.
Maintenance of the ventilator means
regular cleaning of the ventilator
surfaces of dust and cleaning or
replacement of the filters.
Pull the ventilator to remove.
Clean the impeller blades. To remove
dust use a soft brush, doth or a
vacuum cleaner. Do not use water,
abrasive detergents, solvents, sharp
objects. The impeller blades must be
cleaned once in year.
Remove the air flow rectifier.
Remove the filter in front of the
regenerator.
Pull the exchanger cord to remove
from the air duct
Be careful while pulling the Excharger
to avoid damage.
Remove the filter after the exchanger
2.Regenerator and filter maintenance
(4 times per year).

Operation Instruction for the user and the qualified installer
16
Clean the filter as often as it gets dirty,
but at least 3-4 times a year.
Once a 90 day period of operation
expires, the ventilator generates a
sound signal as a reminder to replace
or clean the filter. The signal is
repeated every 5 minutes until the
filter maintenance has been
completed! Clean the filters, let them
get dry and install the dry filters inside
the air duct Vacuum cleaning is
allowed.
The filter rated service life is 3 years.
Contact the Seller for spare filters.
Even regular technical maintenance
may not completely prevent dirt
accumulation on the regenerator
assemblies.
Subject the exchanger to regular
cleaning to ensure high heat
exchange efficiency.
Clean the exchanger with a vacuum
cleaner at least once in a year.
To reset the operating time meter
indication, install the filters and the
regenerator into the ventilator and
then press and hold the button for
10 sec until a long sound signal.
