3. SITING THE LUMINAIR
3.1
The electrical supply to the LuminAir fan is 12V AC from the mains transformer controller and the light is 12V
DC from the mains lighting LED driver. This allows the LuminAir fan & light to be installed within reach of a person
using a fixed bath or shower ie. in the ceiling above. However, direct water spray on the LuminAir should be
avoided as this could reduce the life of the unit.
3.2
Site away from direct sources of heat. Do not site in areas containing excessive levels of grease. If the LuminAir
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.
3.3 DUCTING
The LuminAir must be ducted to the outside to extract moisture laden air which could cause damage to property.
LuminAir can be used with either rigid, flat duct or short runs of flexible ducting (less than 2m).
A condensation trap will be required in the exhaust duct where excessive levels of moisture are found in the air.
HORIZONTAL DUCTS SHOULD SLOPE AWAY FROM THE LUMINAIR AND DUCTS PASSING THROUGH AN
UNHEATED ROOF VOID SHOULD BE INSULATED.
4. SITING THE TRANSFORMER CONTROLLER & LED DRIVER
4.1
THE TRANSFORMER CONTROLLERS MUST NOT BE SITED IN A SHOWER CUBICLE OR WITHIN REACH
OF A PERSON USING A FIXED BATH OR SHOWER. (ARMS REACH = 1.25m).
4.2
Site away from direct sources of heat. The controllers require free air circulation and must not be
covered with any insulating material such as might be in a ceiling or roof void. The Ambient temperature
range of both the LuminAir fan & light and transformer controller is 0 to 40°C.
4.3
Decide where to mount the LuminAir and its controllers and work out the cable runs.
4.4
LuminAir H models
In addition to the above please refer to the fitting and wiring instructions supplied with the SELV12 Ecotronic
humidity sensor for appropriate siting details.
5. FITTING THE LUMINAIR FAN/LIGHT
5.1
Mark and cut a 110mm hole in the ceiling surface where the LuminAir is to be fitted. (Mounting holes 130mmø
centres)
5.2
Drill and plug the fixing holes if these are to be used (See 5.4 below).
5.3
Pull the LuminAir Bezel from the main assembly by gripping it firmly around its centre. Do not prise the Bezel
from the unit as this may damage its clip fastenings.
5.4
Loosen the two screws on the Lamp Housing until the Securing Clamps allow sufficient clearance to
accomodate the ceiling thickness. Then reposition the Securing Clamps against the Lamp Housing and fit the
LuminAir through the hole in the ceiling before retightening the screws to clamp the LuminAir into place.
5.5
If required line up the two permanent fixing holes in the Lamp Housing with the pre-drilled and plugged holes in
the ceiling and fit the screws supplied.
N.B.
Either one of the above methods of mounting the LuminAir fan/light is sufficient. Choose which ever is most
appropriate to the installation.
5.6
Remove the Lamp from its packaging and push it firmly into the Lamp Holder ensuring that the two pins on the
Lamp locate in the Lamp Holder receptacles.
5.7
Refit the Bezel to the Lamp Housing.
6. FITTING THE TRANSFORMER CONTROLLERS.
LuminAir L,T and H.
NOTE: The controller is supplied with a surface mounting box and this should not be recessed.
6.1
Break out the desired cable entry opening(s) in the mounting box. Cable entry glands or grommets should be
used to ensure that the enclosure retains its integrity against dust and moisture penetration.
6.2
The mounting box should be fixed to the mounting surface using screws (and possibly masonry plugs)
compatible with the surface.
FITTING THE LED DRIVER.
6.3
The LED driver should be fixed to the mounting surface using screws (and possibly masonry plugs) compatible
with the surface.
7. WIRING THE LUMINAIR AND TRANSFORMER CONTROLLERS
WARNING:
This appliance MUST NOT be earthed. The controllers MUST be connected to a 220-240V 50Hz
AC single phase mains fan supply. They provide a 12V 50Hz AC Safety Extra Low Voltage (SELV) output for
only one Vent-Axia LuminAir fan unit.
7.1
Ensure that the mains supply is switched OFF before starting any wiring.
7.2
Connection of the controller to the mains supply and the SELV wiring between the controller and the LuminAir
should be in accordance with current IEE Regulations, BS7671 (UK) or the appropriate standards in your country.
7.3
The mains supply should be via a switched spur with a 3A fuse (UK). The installation MUST be provided with a
double pole isolator switch with a contact separation of at least 3mm. The switch should be located outside the
room if it contains a fixed bath or shower, or in accordance with mandatory wiring and safety regulations.
