Do not disassemble or exchange assembly parts and electric circuits by unauthorized
personnel! Hazard of electric shock!
In case of damaged shipment and dent, deformation or distortion of the enclosure,
contact authorized local MRC distributor or MRC personnel.
2.1.2 Installing
Install the equipment on a rigid, nonflammable surface and well-ventilated place. If the equipment is
installed on an unstable surface or floor, abnormal noise may be generated.The bench should be
400~500mm high for ease of operation. Keep enough space between wall and back of the
equipment for better ventilation.
The voltage, frequency and current of the power supply must be rated at least the same as those
designated on the name plate of the equipment. The switch board is recommended to be on the
back right side of the equipment and equipped with outlet matching the power plug of the
equipment with protective ground (PE), and rated capacity of the residual current circuit breaker
(RCD) of the equipment.
The minimum distance away from the back of the oven to the wall, furniture or other
installations shall be 300mm!
Install the oven away from overhead fire sensors, where opening of the door or
exhausting of the fume is possible, in avoidance of triggering of an erroneous fire
alarm!
The oven must not be mounted on a surface of flammable or temperature sensitive
materials, where a hazard could be caused by hot items falling from the oven, for
example when the door is opened!
Keep the oven away from hot-air emitting equipment, direct sunshine, strong
magnetic field and electric sparks!
Neither contamination of high concentration dust or corrosive gas, nor strong airflow
surrounds!
Voltage, frequency and current for power supply must meet the requirements as
designated on the nameplate! Use power socket matching the power plug of the
equipment. Hot line

for single phase equipment must not be
reversed!
Socket for power supply must be equipped with protective ground (PE) to prevent
against hazard of possible electric shock.
