1.1 Notices on installation
WARNINGS
l Install the oven, in a suitable location away from water, and close to a fire extinguisher.
l Installation of the oven must comply with industry standards. Incorrect installation can cause accidents,

l Be sure to connect the power cord in compliance with industry standards.
l Check the power supply to see if it is correct for the specification of the oven. The working voltage range
can not deviate by ± 10% when the oven is working.
Violating this standard can cause electrical shock or fire. If you cannot identify the specification of the
power supply used, consult the supplier.
