FAN DIMENSIONS
Bi Before commencing work, the tables in Fig Bi should be read to ensure the fan will fit in the position
proposed.
THICKNESS OF GLASS
C1 Fans can be fitted in most types of glass with a fixing thickness up to 32mm, with the screws provided.
When fixing thickness exceeds 32mm, the unit should be secured with Extended Fixing Rods, available as an
accessory item (56 81 04). If the unit is to be installed in a location exposed to severe wind turbulence thicker
glass will be required – consult with Vent-Axia Technical Support for advice.

D3 Slacken the two safety catch screws on the face of the housing. Depress the side catches.
D4 Lift off the housing.
D5 Remove the top cover from its housing. Check rating label to ensure that the fan unit is the correct voltage.
D6 Ease back the motor support safety catch located in the left-hand top corner of the base housing. Rotate
motor support assembly anticlockwise until the bayonet catches disengage from the base housing.
D7 Withdraw motor support assembly and place with the impeller downwards.
D8 Separate the base housing from the external grille assembly.

FITTING
For Dimensions see Bi
Measure the glass thickness and determine the length of fixing screw required (C1).
Glass thickness 4 to 17mm – Break/ cut off ends of screws supplied.
Glass thickness 16 to 32mm – Use screw as supplied.
Glass thickness 32mm and greater – Use extended rods (56 81 04) available as an accessory.
E1 From the inside, place the spigot centrally through the fixing hole with the connector hole upwards.
Ensure the rubber seal is correctly located over lugs and around the spigot.
E2 From the outside, place the exterior grille assembly over the projecting spigot, ensure that the grille
louvers are slanting downwards.
E3 From the inside, insert the four thumbscrews through the holes around the spigot. Finger-tighten the
screws progressively, in turn, to give an even pressure round the hole into the glass.
E4 Locate and replace the motor support assembly and turn clockwise until the safety catch is fully engaged.
