FITTING AND WIRING INSTRUCTIONS:

Important Things to Consider Before you Begin

1). Before commencing work, ALWAYS isolate the
mains power supply and remove the fuse in the fuse
box or switch o the circuit breaker in the consumer
unit.

2). If unit is to be used as a replacement for an existing
product, remove existing unit from its location and
disconnect the wiring. Ensure that the wall (back) box
has a minimum depth of 25mm.

3). Certain items in the range will not t into a 4-lug
box. If such a box has been previously installed the
North-South lugs should be removed or bent back to
avoid contact with the new product.

4). Connect the wires as shown in appropriate wiring
diagrams. Use green/yellow sleeving on any earth
conductors not insulated. Ensure terminals are
properly tightened and no bare wire is visible. When
mounting products into mounting boxes make sure
conductors are not trapped.

5). When screwing the unit to the mounting box, do
not over-tighten xing screws. Fixing screws are
supplied with this product.

6). To reduce the risk of discolouration or tarnishing,
avoid installation on wet plaster.

7). Products must be installed in accordance with the
latest building and IEE wiring regulations. If in any
doubt, please contact a qualied electrician.
