If the AC plug of this unit does not match the AC 

outlet you want to use, the plug must be removed 

and appropriate one fitted. Replacement and 

mounting of an AC plug on the power supply cord of 

this unit should be performed only by qualified 

service personnel. If connected to an AC outlet, the 

cut-off plug can cause severe electrical shock. Make 

sure it is properly disposed of after removal.

The equipment should be disconnected by removing 

the mains plug from the wall socket when left unused 

for a long period of time (for example, when on 

vacation).

CAUTION

The 



STANDBY/ON

 switch on this unit will not 

completely shut off all power from the AC outlet. 

Since the power cord serves as the main disconnect 

device for the unit, you will need to unplug it from the 

AC outlet to shut down all power. Therefore, make 

sure the unit has been installed so that the power 

cord can be easily unplugged from the AC outlet in 

case of an accident. To avoid fire hazard, the power 

cord should also be unplugged from the AC outlet 

when left unused for a long period of time (for 

example, when on vacation).

IMPORTANT: THE MOULDED PLUG

This appliance is supplied with a moulded three pin mains plug for your safety and convenience. A 10 amp fuse is fitted in this plug.

If the plug contains a removable fuse cover, you must ensure that it is refitted when the fuse is replaced. If you lose the fuse cover the plug 

must not be used until a replacement cover is obtained. A replacement fuse cover can be obtained from your local dealer.

If the fitted moulded plug is unsuitable for your socket outlet, then the fuse shall be removed and the plug cut off and disposed of 

safely. There is a danger of severe electrical shock if the cut off plug is inserted into any 13 amp socket.
