Installing the switches and cables
1.Check that there are no buried pipes or cables (eg. Electricity, gas, water) behind the switch location (in the wall or above the ceiling).
2.Lay in the cable from the isolating switch to the fan location via the on/off switch (see Fig. E1. For change over switch (COS) see Fig. E2.
3.Lay in the cable from the isolating switch to the point of connection to the mains supply.
WARNING: DO NOT MAKE ANY CONNECTIONS TO THE ELECTRICITY SUPPLY AT THIS STAGE.
4.Install the isolating switch and the on/off switch, see Fig. E1. For change over switch (COS) see Fig. E2.
5.Make all connections within the isolating switch, on/off switch and change over switch (COS) if required.
Note: When installed in a bathroom all switches must be of a pull cord type and must be situated so that they can not be touched by persons making use of the bath or shower.
For Australia only
Permanently connected to the supply and a remote switch operation. Wire directly to the supply through an approved 10A wall mounted surface switch with at least 3mm clearance between contacts.
Preparing the hole
If working above ground level, appropriate safety precautions must be observed.
WARNING: EYE PROTECTION MUST BE WORN DURING ALL DRILLING AND CHISELLING OPERATIONS.
If installing in a wall
1.Check there are no buried pipes or cables in a wall or obstructions on the outside (eg. Electricity, gas, water).
2.Ensure that the centre of the hole is located at least 145mm from the edges of the wall, see Fig. A.
3.Mark on the centre of the duct hole.
4.Use this centre to draw a circle to suit the wall duct (203mm diameter for a WK6/300 or WK6/450).
If core drill equipment is available
5a. Use as directed by the core drill manufacturer.
If core drill equipment is not available
5b. Drill a centre hole right through the wall.
6.Cut the hole. Do not cut right through the wall (the recommended method is to drill a series of holes, close together, around the edge of
the cutting line and remove the brick between the holes with a chisel).
7.Go outside and cut a hole in the outer wall, repeating the process described above.
8.Fit the ducting. Ensuring that the duct slopes down away from the fan to allow drainage of any incoming rain water to the outside.
9.Make good the hole. Allow for the mortar to set before continuing with the installation.
If installing in a window
Obtain a ready cut pane with a correctly located hole 184mm diameter, see Fig. A.
Preparing the fan for installation
1.For window mounting, use the two short ladder strips supplied with the fan.
For wall mounting, use the longer ladder strips supplied with the wall kit WK6/300 or WK6/450.
2.Secure the two ladder strips to the outer grille by positioning them over the hook moulding and snapping them into position.
3.Ensure after fitting the hook moulding that the gasket is in the correct position, see Fig. B.
4.Insert the two screw covers in the two fixing holes in the outer grille.
Mounting the fan in the hole, Fig. C.
If working above ground level, appropriate safety precautions must be observed.
Remove the back draught shutter/grille assembly by pressing the release catches located on the sides of the unit with a 6mm screwdriver or a coin, whilst pulling the grille forward.
If installing with ladder strips
1.Hold up the outer grille to the outside wall or window so that the hole in the outer grille is aligned with the hole in the wall or window.
2a. If wiring from the rear, remove the fan’s terminal cover and rear entry knockout. Feed the cable through the rear cable entry.
2b. If wiring from above, remove the fan’s terminal cover and feed the cable through the top cable entry.
3.Hold the fan assembly to the inside of the wall or window and guide the ladder strips from the outer grille through the slots in the fan assembly.
4.Insert the slotted screws into the pockets around the ladder strip slots.
5.Tighten the screws carefully to make a good seal, do not over tighten the screws.
6.Trim the ladder strips back to the required length, if necessary remove any sharp edges.
If using screw fixings
1.Hold the outer grille up to the outside of the wall so that the hole in the outer grille is aligned with the hole in the wall.
2.Mark the positions of the fixing holes in the top right and bottom left corners.
