THROUGH A WINDOW (ALL MODELS DIAGRAMS 3/4).
1. Cut a hole in the glass to suit fan. This is best cut by a qualified glazier, alternatively,
measure your window and get a new piece of glass with a pre-cut from your glass
merchant and replace.
2. Remove external grille by gently levering the top out with a
small screwdriver and remove the four pozidrive screws and
separate the two halves.
Hold the fan in position over the hole on the inside of the
window and then refit the four pozidrive screws from the
Outside.(Diagrams 1/2)
Caution
– do not over tighten these screws as it is possible that you might crack
the glass, replace the external grille.
3. Electrical: All wiring must comply with current IEE Regulations. If in
any doubt call a qualified electrician.
NOTE: All flaps should open and close together. If they do not, remove the second
flap and remove and replace until it locates properly.
Connect the cable from the fan to a double pole fused spur having a contact
separation of at least 3mm in all poles, must be used and fitted with a 3 amp fuse,
and should be sited outside any room containing a shower or fixed bath. The fan
should not be accessible to a person using either the shower or the bath.
THROUGH WALL FIXING (ALL MODELS DIAGRAMS 1,2&5)
4. Cut a hole through the wall to suit fan and duct then fit the aluminium flexible duct
through the wall (wall fixing kit supplied separately - AVA295/230mm - AVA302/300mm)
making sure that there is a slight tilt to the outside in case any water gets in through the
external grille so it will not run into the room. Make good around the duct. If rigid duct
is used to install the fan it must be a minimum of 290mm long, if flexible duct is used
to install the fan it must be a minimum of 500mm (19 1/2 “) from the fan to the outlet
