EARTHING  INSTRUCTIONS

INSTALLATION

1. Steady, flat location

T his m icrow ave oven should be set on a steady, flat surface.
T his m icrow ave oven is designed for counter top use only.

2. Leave space behind and side

A ll air vents should be kept a clearance. If all vents are covered during operation, the oven m ay overheat and, eventually, 
cause failure.

3. A w ay from  radio and TV sets

Poor television reception and radio interference may result if the oven is located close to a TV, radio, antenna or feeder and so on.
Position the oven as far from  them  as possible.

4. A w ay from  heating appliances and w ater taps

K eep the oven aw ay from  hot air, steam  or splash w hen choosing a place to position it, or the insulation m ight be adversely
affected and breakdow ns occur.

5. Power supply 

• 

C heck your local pow er source.

T his m icrow ave oven requires a current of approxim ately 6 am peres, 230 Volts, 50 Hz.

 

P ow er supply cord is about 0.8 m eters long.

 

T he voltage used m ust be the sam e as specified on this oven. U sing a higher voltage m ay result in a fire or other accident

causing oven dam age. U sing low  voltage w ill cause slow  cooking. W e are not responsible for dam age resulting from  use
of this oven w ith a voltage of am pere fuse other than those specified.

 

T his appliance is supplied w ith cable of special type, w hich, if dam aged, m ust be repaired w ith cable of sam e type. 

S uch a cable can be purchased from  D A E W O O  and m ust be installed by a Q ualified Person.

6. Exam ine the oven after unpacking for any dam age such as:

A  m isaligned door, broken door or a dent in cavity.
If any of the above are visible, D O  N O T  IN S TA LL, and notify dealer im m ediately.

7. D o not operate the oven if it is colder than room  tem perature

(T his m ay occur during delivery in cold w eather.) Allow  the oven to becom e room  tem perature before operating.

T his appliance m ust be earthed. In the event of an electrical short circuit, earthing reduces the risk of the electric shock by 
providing an escape w ire for the electric current. T his appliance is equipped with a cord having a earthing wire with a earthing
plug. T he plug m ust be plugged into an outlet that is properly installed and earthed.

WARNING

Im proper use of the earthing plug can result in a risk of electric shock. C onsult a qualified electrician or servicem an if 
the earthing instructions are not com pletely understood, or if doubt exists as to w hether the appliance is properly 
earthed, and either : If it is necessary to use an extension cord, use only a 3-w ire extension cord that has a 3-blade 
earthing plug, and a 3-slot receptacle that w ill accept the plug on the appliance. T he m arked rating of the extension 
cord should be equal to or greater than the electrical rating of the appliance, or D o not use an extension cord.
