INSTALLATION & WIRING INSTRUCTIONS

IMPORTANT NOTE :

The mains lead on this equipment is supplied with a mouldedplug 

incorporating a fuse.

The value of the fuse is indicated on the pin face of the plug and, if it 

requires replacing, a fuse approved to BS1363 of the same rating must be 

used.

Never use the plug with the fuse cover omitted if the cover is detachable. If 

a replacement fuse cover is required, it must be of the same colour as the 

pin face of the plug.

Replacement covers are available from your Dealer. If the fitted plug is not 

suitable for the power points in your house or the cable is not long enough 

to reach a power point, you should obtain a suitable safety approved 

extension lead or consult your Dealer for assistance. However, if there is no 

alternative to cutting off the plug, remove the fuse and then safely dispose 

of the plug. Do not connect the plug to a mains socket, as there is a risk of 

shock hazard from the bared flexible cord.

WIRING INSTRUCTIONS

WARNING THIS APPLIANCE MUST BE EARTHED.
This appliance must be earthed. In the event of an electrical short circuit, 

earthing reduces the risk of electric shock providing an escape wire for the 

electric current.

The appliance is equipped with a mains lead which includes an earth wire 

for connecting to the earth terminal of your mains plug. The plug must be 

plugged into a socket that is properly installed and earthed.

The wires in this mains lead are coloured in accordance with the 

following code:

• Green-and yellow : Earth

• Blue : Neutral

• Brown : Live

• 

As the colours of the wires in the mains lead of this appliance may not 

correspond with the coloured markings indentifying the terminals in your 

plug, proceed as follows.

• 

Connect the green-and yellow wire to the terminal in the plug marked 
with the letter E or the earth symbol ( ) or coloured green or green-

and-yellow.
