IMPORTANT NOTICE

The following components have potentials above 2000V while the 
appliance is operated.

- Magnetron
- High voltage transformer (Located on inverter (U))
- High voltage diodes (Located on inverter (U))
- High voltage capacitors (Located on inverter (U))

Pay special attention to these areas.
When the appliance is operated with the door hinges or magnetron 
fixed incorrectly, the microwave leakage can exceed more than 
5mW/cm

2

. After repair or exchange, it is very important to check if 

the magnetron and the door hinges are correctly installed.

2.7. Sharp edges

Caution

Please use caution when unpacking, installing or moving the unit, 
as some exposed edges may be sharp to the touch and cause 
injury if not handled with care.

3. MEASUREMENTS AND ADJUSTMENTS

3.1. Adjustment of primary latch switch, secondary latch switch and 
short switch.

1. Mount the Primary latch switch, the secondary latch switch and 

the short switch to the door hook assembly as shown in ILL.

NOTE:

No specific individual adjustment during installation of the 
Primary latch switch, secondary latch switch or short switch to 
the door hook are required.

2. When mounting the door hook assembly to the oven assembly, 

adjust the door hook assembly by moving it in the direction of the 
arrows in the illustration, so that the oven door will not have any 
play in it. Check for play in the door by pulling the door assembly. 
Make sure that the latch keys move smoothly after adjustment is 
completed. Completely tighten the screws holding the door hook 
assembly to the oven assembly.

3. Reconnect the short switch and check the continuity of the 

monitor circuit and all latch switches again by following the
