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.

TECHNICAL AND MAINTENANCE DOCUMENTATION VCR 5

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.
