Electrical Grounding Instructions
This appliance is equipped with a three-prong grounding plug for your protection against shock hazard and should be plugged directly into a properly grounded receptacle. Do not cut or remove the grounding prong from this plug.
The power cord is about 1m long, please pay attention to the installation position of the socket.
The power cord of this appliance should be equipped with a three-prong (grounding) plug which mates with a standard three-prong grounding wall receptacle to reduce the possibility of electric shock hazard from this appliance.
The customer should have the wall receptacle and circuit checked by a qualified technician to be sure the receptacle is properly grounded.
When connecting this cooktop, it is the personal responsibility and obligation of the customer to have a standard two-prong wall receptacle replaced with a properly grounded three-prong wall receptacle.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUND) PRONG FROM THE POWER CORD.
If needed, have the circuit checked by a qualified technician to make sure the receptacle is correctly grounded.
DO NOT use an adapter plug because disconnection of the power cord places undue strain on the adapter and causes eventual failure of the adapter ground terminal.
If only a two-prong wall receptacle is available, it must be replaced with a three-prong (grounding) receptacle by a qualified electrician before plugging in the cooktop.
The installation of appliances designed for manufactured (mobile) home installation must conform with the Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280 [formerly the Federal Standard for Mobile Home Construction and Safety, Title 24, HUD (Part 280)] or with local codes where applicable.
