1. GENERAL INFORMATION
VTR fans are intended for mechanical exhaust ventilation in residential buildings, collective
housing and public utility buildings. They are the basis for the entire ventilation installation,
which includes a duct network, fire dampers, exhaust grilles, diusers and other components.
― HD automation
Integrated into the VTR fan, the HIGROdynamic automated system adapts the fan speed
to the opening degree of the HIGRO
®
AERECO diusers and grilles. This means that the
electronic system lowers the fan speed at low flow volumes, adapting to the lower airflow
resistance in the ducts, and increases the fan speed at higher airflow volumes caused by the
open dampers of the hygroregulated grilles. The HIGROdynamic automated system prevents
improper operation of the ventilation system, in particular excessive noise from grilles and
diusers at low humidity. The automated regulation of operating parameters reduces the
fan's energy consumption.
ATTENTION!
The compact design minimises
the necessary installation space
on the roof. The fans, thanks to
their flexible work and adaptation
to the network parameters, can
be used in buildings of dierent
heights.

2. FAN INSTALLATION
The VTR fans are suitable for outdoor use, in a vertical position only.

To avoid vibrations and their transmission to the building structure, the following must
be used:
- anti-vibration mounts,
- flexible connections between the fan and suction and discharge lines.

The connected ventilation duct should be equipped with an acoustic silencer with properties
specified in the installation design.
Beware of sharp edges and corners.

Disconnect the fan from the mains supply before carrying out any installation or maintenance
work.
All works inside the fan casing and connected to the power supply and fan automated
system must be carried out after the power supply has been disconnected. The installer
is responsible for the compliance with all applicable safety regulations for electrical
connections and protection against accidental contact.
Clearance must be provided around the fan, the automated system and the measuring
stub to allow for future maintenance.
The automated control system must be located in an easily accessible place.
When storing and assembling the fan, the automated control system must be protected
against water penetration.
During all works connected with the fan service one should
- use protective gloves,
- use tools intended for maintenance works.
3. FAN MODELS
ATTENTION!
Before switching on, the fan
must be connected to the ducting
network. The installation must be
performed in such a way that no
contact with moving parts of the fan
is possible. Installation may only be
carried out by qualified personnel.
Before starting the fan, check
that there are no foreign objects
blocking the impeller.

4. ELECTRICAL SPECIFICATIONS AND
CONNECTIONS
― Connecting the HD automated system
The fan with a HD automated system should be connected as shown in the drawing.
To open the casing of a HD automated system use a screwdriver, do not use a power screw-
driver because of the danger of damaging the screws.
1PG11 cable gland enables connection of 1x230 V power supply. The power wires should
be connected to the corresponding terminal blocks 2, according to the above drawing.
The potentiometer 3is used to change the setting of the base pressure. The base pressure
is preset at the factory. Do not change the default connections 4. The automated system
is equipped with a switch 5. The switch-o button is located on the lower surface of the
automated system.
After connecting the power supply, mount the cover of the automated system and tighten it
with screws with 0.8 Nm force, use a torque screwdriver.
Type Power supply Imax. [A] P max. [W]
VTR-71 230 V AC/50 Hz 1.7 170
VTR-72 230 V AC/50 Hz 1.7 170
It is recommended to use an overcurrent circuit breaker.
The type of protection is selected by the electrical installation designer.

5. START-UP
Incorrect start-up can lead to permanent damage of the fan. The start-up can be carried out
by the AERECO service with prior agreement. Before applying voltage you have to check that:
installation materials, waste and tools have been removed from inside the fan,
the fan impeller turns easily without rubbing or jamming,
the fan is securely mounted,
the direction of air flow through the fan corresponds to the installation design,
electrical connections have been made correctly,
the ductwork is securely fastened using suitable materials,

electric wires connected to the fan are properly fastened, without risk of breaking or
fraying due to vibrations,

the protective (earthing) conductor and possibly also the equipotential bonding conductor
are correctly connected to the fan and to the grounding point (busbar)
safety devices have been installed and they comply with the general safety regulations
and the requirements of section 3 of the documentation,
the voltage supply corresponds to the rated values within the tolerances: max. voltage
+ 6%, - 10% according to EN 60038:2012 (unless other tolerances are indicated on
the nameplate of the fan).
After applying the voltage, check that the fan works without any abnormal noises.
6. USE
The fans require periodical service twice a year which must include checking the general
condition and cleaning the impeller and the housing. Before operation, service or repair of
the device, it is necessary to make sure that

the employee performing the inspection has been trained and knows the safety rules,
the power supply is disconnected (circuits of all poles) and that it is not possible for third
parties to switch on the fan,
the fan impeller is no longer rotating.
Do not use pressurised equipment (compressed air or pressurised water) to clean the fans.
When cleaning, make sure that the weights balancing the impeller are in place and the
impeller is not deformed. After cleaning check whether the impeller is not jammed and
whether the fan work is not accompanied by abnormal sounds.
7. TRANSPORT AND STORAGE
Before installation, the products must be protected from direct exposure to water, dirt and
atmospheric conditions. They should be stored in a dry place.
ATTENTION!
Start-up must be documented by
an entry in the warranty card.
Causing damage to the fan as a
result of installation error or the
use of inappropriate electrical
protection is grounds for
invalidating the guarantee.
ATTENTION!
Service notifications should be
made via the website: www.ser-
wis.aereco.pl
Failure to carry out the inspection
will result in the loss of warranty.
