GENERAL

The VBP+ R is a very-low-pressure assistance fan delivering pressure compatible with the design of passive stack ventilation.

It is intended to improve and optimize the draught of passive stack ventilation ducts, and belongs to the category of hybrid ventilation systems.

It is available in 2 pre-configured versions:

ST version (VB21184): Version pre-configured in ST mode, uncontrolled stand-alone, at constant speed adjustable on a builtin potentiometer.

MS version (VB21183): Version pre-configured in MS mode, controlled by a management system:

 Management of the fans in groups (up to 5 groups of 5 VBP+),

 Individual setting/adjustment of the speed of each fan according to the site configuration (number of storeys, ductwork...)

 Speed control of each fan according to the temperature,

 Indication of operation of the system and alarm reporting.

This version requires the use of two specific types of modules.

The versions (ST and MS) are the same product with different pre-configurations. It is therefore possible to change from one version to the other. The possible change of configuration will imply a specific identification of the product

(the label states the baseline configuration).

MAIN FUNCTIONS

 Hybrid operation: in passive stack or mechanical mode (low pressure losses when stopped)

 Compatibility with demand controlled ventilation

 Low power consumption

 Direct power supply at 230 V~, 50-60Hz

 Adjustment of the speed according to the temperature ("MS" mode)

 Reporting of information for working or default (“MS” mode)

 Possibility of grouping several ducts (aeraulic cross-section 984 cm²)

Remarks:

RANGE OF USE

 Ventilation of residential buildings, offices, and other general-purpose premises

 Renovation or new construction 1

 Individual or collective ventilation ducts, which may be made of concrete or metal.

 Use of the fan on ducts serving connected gas-fired appliances is subject to specific approval by the competent authorities.

 The height of the buildings equipped varies according to the regulation flow rate requirements, which are specific to each country.

 In France, the MS version of this product is sold under the name “HELYS H800 R” by the Acthys Company.

INSTALLATION

FITTING ON STACK

The components necessary for adaptation to the roof ducts vary from one site to another.

In the case of an individual duct, a horizontal platform, located at the level of the emergence of the duct, is necessary for attachment and for airtightness with the fan. A plane plate of the right dimensions, attached to the top of the stack, is sufficient.

For the grouping of ducts, an adaptation plenum compliant with the recommendations stated below is necessary to ensure proper aeraulic operation of the whole (minimized pressure losses) and for attachment and tightness with the fan(s).

General recommendations for the placement of adaptation components:

7/20

 The adaptation components must be made of a material strong enough to bear the weight of the fan(s).

 The latter must be fastened to the stack securely and so as to assure a good seal with it; the plenum as a whole must also be perfectly sealed.

TF5774_A Aereco S.A.

CASE OF AN INDIVIDUAL DUCT

For a rectangular duct, the constraints are the following:

 The top platform must be rectangular and measure at least 600 x 600 mm.

 The opening cross-section of the duct must not exceed 245 x 245 mm if it is desired to avoid reducing its cross-section.

 The fan must be centred on the duct.

For a circular duct, the constraints are the following:

 The top platform must be rectangular and measure at least 600 x 600 mm.

 The opening cross-section of the duct must not exceed Ø350 mm if it is desired to avoid reducing its cross-section.

 The fan must be centred on the duct.

8/20

CASE OF DUCTS GROUPED UNDER A SINGLE FAN

For all grouped ducts configurations, an adaptation plenum is necessary. The plenum must:

 provide a top platform measuring at least 600 x 600 mm.

 provide a circular outlet Ø350 mm centred on the stack.

 ensure a minimum height of air between the end of the stack and the outlet section Ø350 mm, that is to say 120 mm or 180 mm.

 The fan must be centred on the outlet section Ø350 mm.

Example of a typical stack of the collective and individual type:

TF5774_A Aereco S.A.

CASE OF DUCTS GROUPED UNDER 2 FANS

For all grouped duct configurations, an adaptation plenum is necessary.

 The plenum, even if made in a single piece, must provide 2 distinct volumes, perfectly sealed from one another.

 For each of the 2 units, the plenum must provide a circular outlet Ø350 mm centred as closely as possible on the grouped duct.

 Ensure a minimum height of air between the end of the stack and the outlet section Ø350 mm, that is to say 120 mm or 180 mm.

 The fans must be centred on the outlets Ø350 mm.

 Each Ø350 mm outlet must be at least 1,000 mm from the other and at least 500 mm from the bulkhead separating the volumes.

The plenum must provide 2 virtual platforms measuring at least 800 x 600 mm each (see example below).

Example of grouping of 8 individual ducts:

9/20

ANTICIPATION OF MAINTENANCE AND CHIMNEY SWEEPING CONSTRAINTS

In order to allow access to the ducts located under the fan (inspection, chimney sweeping) it may sometimes be necessary to incorporate one or more of the following features:

 Soot door. This is generally located on the side of the stack or of the plenum.

 Top plate tipping system (with hinges and catches).

 Attachment that can be removed from and refitted on the top plate.

TF5774_A Aereco S.A.

INSTALLING THE FAN

1) Ensure the proper adaptation of the fan on its stack (see section above).

The plate holding the outlet Ø350 mm can be designed with 3 crimped M8 nuts positioned as shown below to allow the attachment of the fan.

10/20

2) Remove the fan from the pallet.

 Use only the 2 handles located under the uprights to handle the fan.

 Wear suitable gloves (some of the metal parts may be sharp)

 Do not set the fan down on an obstacle that might damage the turbine.

 Do not set the fan flat (horizontally)

TF5774_A Aereco S.A.

3) Place a gasket as a seal between the top plate and the base of the fan.

11/20

4) Attach the fan to its specific adaptation using 3 x Ø 8 mm stainless steel screws + washers.

Note: The 2 handles can be removed by pinching them; this eliminates a potential source of noise due to mechanical vibration.

CONNECTIONS

All electrical connection operations must be made by a qualified professional and comply with the standards in force.

No cable used for the connection may pass though the interior of the stack or of the plenum.

GENERAL CONNECTION DIAGRAM

The following drawings show the electrical connections according to the chosen working mode (ST or MS mode). Two cases can be identified:

 Case A = 230 V~ electrical box is far from the fans (for example in the stairs)

 Case B = 230 V~ electrical box is close to the fans in terrace

TF5774_A Aereco S.A.

General isolating switch: The use of a switch - general isolating switch is recommended upward the entire individual proximity switch. Check that the switch are well opened (no supply) during the installation.

There must be an individual protection for each fan, using a fuse or a circuit breaker (thermal protection, overload protection or similar) according to standard EN 60335-1.

Advised fuse: 16A maximum

The supply cable must have 3 conductors, be between Ø6 mm and Ø12 mm, comply with the installation standards in force

(colour code in particular), have conductors with a cross section of at least 1.5 mm², and be able to withstand the environment in which it is installed (in particular, be resistant to UV).

Switch - general isolating switch: A manual circuit breaker must be located on the 230V~ supply, upward the fan(s). It has to be visible and accessible from each connected fan. It can be shared by several fans or individual depending on the installation, to allow a quick and easy manual power cut in case of problem or accident.

ST mode:

 Case A: 230 V~ electrical box is far from the fans (for example in the stairs)

12/20

 Case B: 230 V~ electrical box is close to the fans in terrace

POWER CONNECTION

The fans are supplied with 230V~ using a junction box to be installed at the base of the fan. The connection must be done directly on an electrical box and in no case on a traditional socket.

The power connection cable of the fan can be identified by the annotation “230 V – 50 Hz” at its edge. Each wire is marked:

 “N” = neutral

 “PE” = earth protection

 “L” = phase

Edge of the power connection cable

Make the connection in accordance with standard practice via an IP65 junction box installed at the base of the fan.

Recommendation: Add a bonding jumper, connected to the stud provided for this purpose on the carcass of the fan 2 .

CONFIGURING IN ST OR MS MODE

The versions (ST and MS) are the same basic fan with different pre-configurations. It is therefore possible to change

from one version to the other if necessary. The pre-configured mode is marked on the label on the outside of the product.

If you wish to change the management mode, proceed as follows:

Check that the power supply has in fact been cut off for at least 5 minutes before starting (to eliminate the risk of electrical shocks from the discharging of certain components).

1) Remove the cover from the top of the fan.

2 Connected to the ground, this cable helps to reduce the product’s EMC emissions and limits the danger in the event that the cable leading to the engine is cut off (secondary discharge device).

TF5774_A Aereco S.A.

16/20

TF5774_A

2) Remove the cover from the protection box of the user interface

Aereco S.A.

3) Place the jumper at bottom left according to the chosen management mode:

17/20

 on pins 1 & 2 for the "MS" mode

 on pins 2 & 3 for the “ST” mode

CONNECTION IN ST MODE

The ST mode doesn’t require any additional specific connection other than power connection.

CONNECTION IN MS MODE

Check that the power supply has in fact been cut off for at least 5 minutes before starting (to eliminate the risk of electrical shocks from the discharging of certain components).

In this mode, each fan has its own control line. The operation consists in connecting the cable from the MS device to the control cable of the management module (FAN module). For the complete installation of the MS mode, refer to the installation manual of the MS management components.

The cable must be between Ø6 mm and Ø12 mm, comply with the installation standards in force, have 4 conductors each having a cross section of at least 1.5 mm², be no longer than 25 m between the fan and its management module, and be able to withstand the installation environment (in

particular, be resistant to UV). These recommendations ensure the EMC and limit the tension lost. Above this length, the good working of the appliance won’t be guaranteed.

The cable must not include a yellow & green conductor, the colour pair used only for earth wires.

The current in these cables does not exceed 20 mA.

The “MS” cable of the fan can be identified by the annotation “MS” at its edge. Each wire is marked with a number: 1,

2, 3, 4. Connect the cable and mark each wire (using colours for example) in order to identify which wire is connected:

1, 2, 3, 4.

MS cable edge

Make the connection in accordance with standard practice via an IP65 junction box installed at the base of the fan.

STARTING UP / OPERATION

 Before commissioning, check that the fan is securely attached to its stack and that no object has been left inside the duct or might interfere with the turbine.

 Do not insert anything through the fan.

 Check that a bonding jumper is in fact connected to the body.

ST MODE

1) Power up the appliance. It then starts.

The motor technology used may lead to starting errors. If this happens, the appliance fails to start and begins vibrating slightly. Do not touch anything; the appliance will itself initiate a starting cycle, until it actually starts.

2) To adjust the speed, unscrew the plug on the left.

Take all the usual precautions, because the appliance is still working. Do not insert anything through the unit.

18/20

Set the speed level, operating the potentiometer.

Any curve between the minimum and maximum curves presented in the graph below can be obtained. The number of possible adjustments between these curves is infinite. Intermediary curves are given as examples (not exhaustive).

3) Screw the plug back. Then put the top cover back on the fan.

TF5774_A Aereco S.A.

MS MODE

1) Power up the appliance, which then waits for a setpoint command from the management system.

For the rest of the starting up process, please refer to the installation manual of the management modules.

Once the MS mode has been activated, the appliance should start.

The motor technology used may lead to starting errors. If this happens, the appliance fails to start and begins vibrating slightly. Do not touch anything; the appliance will itself initiate a starting cycle, until it

actually starts.

19/20

MAINTENANCE

PRIOR WARNINGS

Before doing any work on the appliance:

Cut off the power.

Wait at least 5 min after cutting off the power supply before intervention on the appliance.

The appliance may still be charged even though the 230 V~ power supply circuit has been cut off, leading to a risk of electrical shocks.

It is recommended to use some gloves to move the product (some metallic parts of the product can be sharp).

The appliance may be stopped but restarts automatically (for example if there is a momentary interruption in the control circuit of the MS version), with a risk of injury.

 Never insert anything through the fan, and in particular the suction stream in which the turbine is located.

 Never handle an appliance or remove it from its stack when it is connected.

 Cut off the power supply and make sure that it cannot be reconnected.

 Wait for the turbine to come to a full stop.

MAINTENANCE AND CLEANING

We recommend carrying out a visual observation of the proper operation of each fan once a year and if necessary cleaning its blades.

1) Cut the plastic clips that secure the access hatch to the fixed part of the fence.

DO NOT CUT the metallic staple linking the access hatch to the support.

2) Open to clean the inside of the fan.

3) Close the access hatch and put some new plastic clips.
