Transportation and Storage:
During transportation, please handle the appliance carefully and DO NOT put
upside down –this will prevent damage of the enclosure and inner parts. The
packaged device should be stored in a well-ventilated warehouse of no
corrosive gas. Please take appropriate precaution against rain.
Installation:
The Assembly of the Rubber Feet:
▪The rubber feet must be mounted on the appliance. Do not use the oven
without the rubber feet.
▪Fasten the rubber feet to the oven bottom with screws.
▪Adjust the oven height by the screw or unscrew the rubber feet directly.
▪Install this device on a flat and stable surface.
▪Remove the protective film.
▪Take out the trays in the oven and clean them.
▪Wipe the internal and external of the oven with a wet cloth and then dry
them with a soft cloth.
The Connection of Power Supply
▪Please make sure that the applicable power supply voltage and frequency
comply with those indicated on the data plate prior to energize the device.
▪After installation of the oven, install a bipolar switch between the oven and
the power grid so that the contact opening distance between them can be
maintained at least 3mm and the input power is appropriate.
▪The oven shall be connected with the earth wire in the power grid.
▪The oven must be in a system of equipotential so that the power can be
maintained the same as indicated on the data plate. Such connections can
be only achieved among the labelled wire terminals of different appliances.
▪The minimum valve of the equipotential conductor component is 10mm2.
▪Connect the power cord to the power supply and ensure that the power
cord is connected reliably and in it’s proper place.
Notice:
▪Make sure the connection of the power cord complies with the industrial
standard.
▪The supply voltage should be in accordance with the working voltage of the
device. The supplied voltage shall not exceed the voltage range by ±10%,
otherwise it may cause fire or electric shock when violating the industrial
standard. If you are not sure about the specification of the voltage, please
contact the manufacturer.
▪The device is equipped with grounding bolt at the back. Ensure it is
connected to ground wire that complies with the copper wire no less than
1.5mm².
▪After installation, check the tightness of all the connections, the correct
functioning of the voltage and the reliability of the ground wire.

5. Set the device on a flat, secure surface, and make sure the sides are away from
non-combustible material (e.g. Brick walls or windows) no less than 10 cm, and the
rear at least 20 cm.
6. When installing, please ascertain that the device is far away from water or snow
and it is advisable to place it near a fire extinguisher. The main reason for electric
shocks and damages to the oven is a moist oven.
7. The installation must comply with the industry standard. Incomplete installation
may cause accidents like electric shocks or water leakage.
8. The rubber feet must be mounted on the device safely. The oven without rubber
feet cannot be used.
9. According to the wiring regulations, the fixed wiring connected to this appliance
must be equipped with an all-pole disconnect switch (leakage switch), with at
least 3mm contact opening distance of each pole of the switch. It is also advised
to install grounded leakage protection switch. Do not pile items in front of the
switch for convenient operation.
10. The installation of this device should be performed by a trained technician.
11. Do not store any flammable, explosive substances or volatile gases near the
device. The ambient temperature should be lower than 45℃and the relative
humidity should be lower than 85%.
Special Safety notes:

▪High temperature may cause scalding. Do not touch the appliance directly with
bare hands due to high temperatures during or after the operation.
▪During a thunderstorm, cut off the power supply asap to avoid damage done by
the lighting stroke.
▪Do not destroy the control panel with hard or sharp objects.
▪Please do not tread, extrude, bundle up or forcefully twist the power cord,
otherwise the power cord may become damaged and cause fire or electric
shock.
▪The oven is intended for baking cakes, pies, poultry, beef, pork, break, steak and
so on. Do not use it for other purposes.

The Usage of the Timer:
▪The cooking time can be set by rotating the timer clockwise. When the time is
up, you can hear a tick sound and the oven will close automatically.
▪During cooking, the oven can be turned off manually by just rotating the timer
anti-clockwise to the “0” position.
Convection Heater:
▪Turn on the oven power supply
▪Set the temperature (0-300℃) you desire
▪Rotate the time to the time (0-120min) needed. The temperature indicator, timer
indicator and the internal light of the oven will come on.
▪When the temperature reaches the heat you need, the power indicator will be
off. If the temperature drops, the temperature indicator will be on again. This
process will be repeated automatically.
Safety:
▪Do not press and hold down the button continuously
▪The excess vapor will come out from the drainage pipe
▪The function of “convection heater” and “top heating” can only be operated
separately, and cannot be used simultaneously.
▪Do not operate any switches with wet hands otherwise it may cause electric
shock
▪When using the device, do not place any objects onto the oven due to the heat
generated it can damage the objects.
▪During use, the metal accessories and glass door will get hotter, therefore do
not touch.
▪The heat elements cannot be submerged in water. If water comes into contact
with the connection part of the heating elements, it may cause short circuit or
other consequences.
▪If there’s water in the chamber, do not pour out the water towards the glass
door, or the glass door may break.
▪Do not place heavy objects (120KG (2801b) onto the oven.
