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

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 is not intended for use by young children

or infirm persons without supervision.

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

cap with your knuckles. Ensure that you have the motor

unit in a secure grip so you do not drop it when it loosens.

• Then loosen the wall frame by using a screw–

driver pressing the lock button as shown in Figure (B)

• Vent-Axia wall kits and external grilles are available as

accessories. (Figure E).

H. I.

The fan’s wall seal has a short spigot which fits inside the Ø100

mm pipe. Make sure when mounting to adapt the length of

the wall pipe so it does not push back the wall seal so the fan

impeller cannot rotate. Always customise a wall pipe, existing

or new, so it ends about 5 mm inside the wall surface where

the fan is to be installed. The wall frame with its seal is prepared

with 5 cable entry points (Figure F) for concealed electrical

connection or surface-mounted cable using the dimension

shown in Figure G.

• Make sure that the gasket is properly installed on the wall

frame, place it in the appropriate place and centre it in the

pipe.

The wall frame can be offset horizontally by placing a spirit

level on its support points

(Figure H and I).

Always use a qualified electrician

All electrical connections 100-240V must be performed by a

qualified electrician. Any electrical work on the product must

utilise a voltage break.

Electrical connection can be made according to the wiring

diagram on page 8-9 and the fan is suitable for connection to

either 100-240VAc or 12VDC.

NOTE: The internal cable route must be as indicated as

figures K/K1 (240VAC) and L (12VDC) to prevent the cable

blocking the locator’s for the motor assembly.

• Mark the three attachment points for the appropriate

screws to the substrate (Figure J).

Tighten the screws so that gasket seals against the wall.

Mounting the cover on the wall frame

• The fan is double insulated and must not be earthed. When the electrical connection is made place the cover back over the

wall frame fitted into the housing hole (Figure P).

Q. R.

• Next, fold the cover over the wall frame (Figure Q).

• Ensure the catch the screwdriver is pointing to (Figure R) engages properly.

• Make sure that the cover is firmly seated in the hook on the wall frame and latch by pulling a bit of cover.

• Finally put the motor unit in place (Figure S). Be careful when fitting motor unit, the impellor can be damaged if the unit is

forced in at an angle.

Operating and installation instructions

For the user

Vent-Axia Svara®

Automatic functions and settings via app

Activate the app:

You have to use a code to activate the app, the code is

unique for each fan. Enter the code or scan it through your

phone. Your unique code is on the back of the user guide and

on the right leg of the motor unit (Figure T).

Learn more about all the possibilities with our app

at www.vent-axia.com/svara

Default setting:

Vent-Axia Svara is programmed to cope with the vast

majority of installations.

The fan works continuously at a trickle flow of 10l/s.

When the fan senses somebody in the room it increases

the flow to 16l/s.

If the humidity rises rapidly, for example when the shower

is on, the fan goes up to maximum flow at 30l/s.

When the fan senses the humidity level has returned to

normal it reverts to the trickle flow of 10l/s.

If other settings or functions are desired, download the

Vent-Axia Connect App from the App Store and Google

Play.

Requirements for functionality

Versions of the operating systems are updated continously,

for information go to: www.vent-axia.com/svara.

Fault indication:

Red LED on the fan indicates power failure when the

calendar function has been activated.
