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

• 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.

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
