DESCRIPTION

Supra axial extract fans are suitable for domestic bathrooms and W.C’s. They are available as wall or panel/ceiling mounted models with shutter, timer, humidity and PIR combinations.

INSTALLATION

IMPORTANT: The fan should only be used in conjunction with fixed wiring.

PANEL/CEILING MOUNTING

For panel/ceiling mounting the fan should be installed into a duct protected by an exterior air grille that must comply with the standard requirements of your country to prevent access to the fan’s impeller.
Cut a 105mm diameter hole.
Push the two clips on the bottom of the fan and pull the grille away from the chassis.
Using the built in spirit level bubble as an aid, mark the screw centres through the holes in the fan back plate. Drill, plug and screw into position.
After installation, ensure impeller rotates freely and the shutters can open.
Replace the grille and ensure the clips engaged.

MOUNTING

Push the two clips on the bottom of the fan and pull the grille away from the chassis.
Using the built in spirit level bubble as an aid, mark the screw centers through the holes in the fan back plate. Drill, plug and screw into position. Fix exterior grille into position with the louvres positioned downwards. (Note:- The grille must comply with the standard requirements of your country to prevent access to the fan’s impeller. The wall kit used in this installation should provide a minimum ducting length of 100mm from the fans back plate to the inside of the external grille).
After installation, ensure impeller rotates freely and the shutters can open.
Replace the grille and ensure the clips engaged.

Warning: the fan and ancillary control equipment must be isolated from the power supply during the installation / or maintenance.
