VCR fans are intended for mechanical exhaust ventilation in residential buildings, collective
housing and public utility buildings.
Unlike standard fans, the working specifications of VCR fans are adapted for compatibility
with HIGRO® systems.
HD automation
Integrated into the VCR 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.
1. GENERAL INFORMATION
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 both
in tall and short buildings.

The VCR fans are suitable for both indoor (horizontal and vertical installation) and outdoor
use in variable weather conditions (horizontal installation).
·The fan installed outdoors should be equipped with an ejector protecting it from pre-
cipitation. The active surface of the ejector may not be smaller than the surface of
the fan ejection opening.
·If it is necessary to reduce the noise level of the fan, it is recommended to use an
acoustic ejector.
·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.
·Watch out for sharp edges and corners.
·Disconnect the fan from the mains supply before carrying out any installation or main-
tenance 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.
·During installation and storage of the automated equipment, it must be protected
against the ingress of water.
·During all works connected with the fan service one should
- use protective gloves,
- use tools designed for maintenance work.

ATTENTION!!!
The fan must be protected from
the atmospheric conditions
during storage.

4. ELECTRICAL SPECIFICATIONS AND CONNECTIONS
To open the casing of a HD automated system use a screwdriver, do not use a power screwdriver 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, in accordance with point 4 of the technical and propulsion documentation.
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.
After connecting the power supply, mount the cover of the automated system and tighten it with screws with 0.8Nm force.

·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, possible 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 wire fixing is secure and made using the correct 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 voltage you have to check that:
·the fan works without any abnormal sounds.
5. START-UP
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.

5. START-UP
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.
·The fan bearings do not require lubrication and should be replaced if faulty.
·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, make sure that the fan works without any abnormal noises.
·Check that the impeller is not jammed and that the motor protection is not loosened.
6. USE
ATTENTION!!!
- Service notifications should
be made via the website:
www.serwis.aereco.pl
- Start-up must be documented
by an entry in the warranty
card.
ATTENTION!!!
- Failure to carry out the
inspection will result in the
loss of warranty.
