•Excessive oil or a grease laden atmosphere.

•Corrosive or flammable gases, liquids or vapours.

• Ambient temperatures higher than 40°C or less than –5°C.

• Possible obstructions which would hinder the access or removal of the Fan.

SAFETY AND GUIDANCE NOTES

A. All wiring to be in accordance with the current I.E.E. Regulations, or the appropriate standards of

your country and MUST be installed by a suitably qualified person.

B. The Fan should be provided with a local isolator switch capable of disconnecting all poles, having

a contact separation of at least 3mm.

C. Ensure that the mains supply (Voltage, Frequency, and Phase) complies with the rating label.

D. The Fan should only be used in conjunction with the appropriate Vent-Axia products.

E. The fan should only be used in conjunction with fixed wiring.

F. When the Fan is used to remove air from a room containing a fuel-burning appliance, ensure that

the air replacement is adequate for both the fan and the fuel-burning appliance.

G. The Fan should not be used where it is liable to be subject to direct water spray for prolonged

periods of time.

H. Where ducted Fans are used to handle moisture-laden air, a condensation trap should be fitted.

Horizontal ducts should be arranged to slope slightly downwards away from the Fan.

I. This appliance can be used by children aged from 8 years and above and persons with reduced

physical, sensory and mental capabilities, or lack of experience and knowledge, if they have been

given supervision or instruction concerning the use of the appliance in a safe way and

understand the hazards involved.

J. Young children should be supervised to ensure that they do not play with the appliance.

K. The exterior grille should be at least 2.3m above the ground to prevent people from being able to

access moving parts. If the external grille is positioned between 0-2.3m from the ground,

Please use the Vent-Axia wall kit as detailed below to ensure people cannot access the fans

DESCRIPTION

The Lo-Carbon Silhouette SELV range from Vent-Axia is a 100mm extract fan for domestic

bathrooms and WC’s available as wall or panel mounted models. Model options with shutter,

timer and auto humidity control.

ACCESSORIES (not supplied)

A range of 100mm wall kits are available for installing into most walls using telescopic liners

supplied. (White – 254102, Brown – 254100)

A. INSTALLATION

SITING THE CONTROLLER

1. The controller must not be installed in a shower cubicle or enclosure. It must be sited

away from direct sources of water spray and out of reach (1.5m) of a person using a

fixed bath or shower.

2. Site away from direct sources of heat. Ambient temperature range 0 to 40ºC. Do not

site in an area containing excessive levels of grease.

3. Decide where to site the controller and fan (see section siting the fan), and work out the

required cable runs.

SITING THE FAN

1. The electrical supply to this fan is 12V DC SELV from the mains controller. This means

that the fan may be installed within reach of a person using a fixed bath or shower, i.e.

in a nearby wall. However, the fan must not be placed where it could be submerged in

water or regularly exposed to direct water spray, e.g. from a shower head whether

permanently fixed or movable.

2. Site away from direct sources of heat. Ambient temperature range 0 to 40ºC. Do not

site in an area containing excessive levels of grease.

3. If the fan is installed in a room containing a fuel burning appliance the installer must

ensure that air replacement is adequate for both the fan and the fuel burning appliance.

If the fan is used to supply air into the room the installer must ensure that the fan intake

is located at least 600mm Away from any flue outlet.

4. Ducted Applications. These fans can be used with short lengths of rigid ducting, but

check details first with your Vent-Axia sales centre. Where an excessive amount of

moisture is present in the air, a condensation trap will need to be installed in the

exhaust duct. Horizontal ducts should slope away from the fan unit. Ducts passing

through an unheated roof void should be insulated.

5. A short circuit of the airflow should always be avoided by siting the fan as far away as

possible from and opposite to the main source of air replacement. FIG.1

PANEL/CEILING MOUNTING

IMPORTANT: The fan should be installed into a closed duct system or protected by an

exterior air grille.

1. Cut a 105mm diameter hole in the fixing surface.

2. Remove the grille by loosening the screw at the bottom of the grille.

3. Mark the screw centres through the holes in the fan back plate. Drill, plug and screw

into position.

4. Securely attach ducting.

5. Replace grille and tighten the screw.

WALL MOUNTING (Wall kit not supplied – see Accessories above)

1. Cut a 115mm diameter hole through the wall and insert the wall sleeve with the large

diameter sleeve on the outside. Slope the sleeve slightly downwards away from the

fan. Cement both ends into position flush with the wall faces.

2. Remove the grille by loosening the screw at the bottom of the grille.

3. Mark the screw centres on the wall through the holes of the fan back plate. Drill plug

and screw into position.

4. Repeat for the external grille sub-frame. Fix exterior grille into position with the louvres

positioned downwards.

AFTER INSTALLATION ENSURE IMPELLER ROTATES FREELY

B. WIRING.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE

ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION / OR

MAINTENANCE.

IMPORTANT

•The Controller MUST be surface mounted to allow air to freely circulate around the

unit. When installed in a loft void it MUST NOT be enclosed or covered with insulation.

•The fan should only be used in conjunction with fixed wiring.

•The cross - sectional area of supply cord used should be ranged from 1 -1.5mm2.

•Cable entry can only be made from the rear of the fan.

1. Select and follow the appropriate wiring diagram (Fig. 2 & 3).

2. Check all connections have been made correctly and ensure all terminal connections and

cable clamps are securely fastened.

3. Ensure the impeller rotates and is free from obstructions.

C. SETUP

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED

FROM THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.

ACCESSING THE CONTROL SETTINGS – (Fig. 4)

1. Loosen the screw in the bottom of the grille and remove the front grille.

TIMER ADJUSTMENT (100SVT AND 100SVH MODELS)

BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY.

TIMER SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Remove the fan grille. The overrun timer is factory set to approximately

15 minutes. This timer period can be adjusted between

approximately 3-30 minutes by altering the adjuster on the control PCB.

2. To REDUCE the operating time, use a small screwdriver to turn the

adjuster Fig.5. CLOCKWISE.

3. To INCREASE the operating time, use a small screwdriver to turn the adjuster

Fig.5. ANTI-CLOCKWISE.

4. Replace the fan grille.

HUMIDITY SET-POINT ADJUSTMENT (100SVH MODEL ONLY)

BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE

MAINS SUPPLY. HUMIDISTAT SHOULD ONLY BE ADJUSTED BEFORE

OR DURING INSTALLATION.

1. Remove the fan grille. The controller is factory set to switch on at about

70% RH. The humidity set point can be adjusted from 65-95%RH by

altering the adjuster on the control PCB.

2. To LOWER the set-point use a small screwdriver to turn the adjuster

Fig.5. ANTI-CLOCKWISE. This makes the controller MORE sensitive.

3. To RAISE the set-point use a small screwdriver to turn the adjuster

Fig.5. CLOCKWISE. This makes the controller LESS sensitive.

4. Replace the fan grille.
