Electric Baking Oven: Operation Manual
Ⅰ. Brief Introduction
This series of products, with a novel style, bright colors & luster and practical structure, have
the characteristics of convenient operation, speedy temperature rising, excellent heat-preserving
performance, energy saving, etc., and are suitable for baking food such as various kinds of cakes,
cookies, meat and medicinal materials, etc. Bread and cakes roasted with this type of products,
that are known as the optimal baking devices, will be uniform in colors & luster, eat crisp &
palatable, and be perfect in the aspects of both flavor and taste.
Please read this Operation Manual carefully before operation and keep it properly.
Ⅱ. Performances and Features
Each layer of baking ovens under this series can be controlled separately, and the upper
temperature and the bottom temperature can also be regulated respectively, several layers can be
put into operation simultaneously, or one single layer can be used independently. The
temperature of a baking oven can be discretionarily adjusted within the range of 20~300℃and
could be automatically detected on scheduled time.
This baking oven has been equipped with an over-temperature protection device. In case
that the malfunction of a automatic temperature controller occurs with the power supply on and
the heat-emitting tube in operation, the electric connections of the main power supply will be
automatically Switched off, so as to avoid the occurrence of fire and electric shock, as well as to
insure the security of persons and surrounding environment.

Product Instruction for Bread Fermenting Box
Ⅰ. Brief Introduction
OVP Series bread fermenting boxes are a new generation of electric-heating products that have
been developed basing on the principle and requirements of bread fermentation. The traditional
fermenting devices can only control the heating humidity of water and the heating temperature of
gas, but have not the function of adjusting the humidity. By means of advanced electronic
temperature and humidity controllers, the temperature and humidity inside the boxes of this
series of products can be adjusted respectively. Making use of electro-thermal tubes and through
electronic temperature control circuits, the most appropriate environment for fermentation of
bread is achieved when the humidity inside the boxes is adjusted to a range of 80-85% while the
temperature is adjusted to a range of 35-40℃, which facilitates the full fermentation of bread
moulds during their latter fermentation processes after they have been formed. The products
come with advantages such as compact design, beautiful and dignified appearances, convenient
operation and reliable functionalities, etc., which therefore are absolutely necessary equipment
used to improve the quality of bread productions.
Please read this Product Instruction carefully before use, and keep it appropriately for further
reference.
Ⅱ. Key Technical Parameters
Notes: 1. Production capacity is based on the output of bread. 2.All data are subject to change
without notice.
Ⅲ. Installation
1. The series of machines should be used only in an indoor environment where the relative
humidity is within the range of 45-85% and the temperature is higher than 5℃. The machine
body should be placed firmly and evenly. The space between the machine body and the wall
should be no less than 10cm. The wheels should be locked so as to avoid any possible
movement of the machine body. The series of machines should not be adjacent or close to
floor and wall that are made of wood. Items that are combustible or flammable should not be
placed around the machines.
2. Two-poled electric switches should be equipped in the power supply circuits, and the
disconnection spacing between the two poles of a switch should be large-enough
(disconnection spacing between the two poles of a switch should exceed 3mm); Furthermore,
the power supply circuit should be equipped with a leakage protection circuit breaker with 2
poles, 220V voltage rating, 16A current rating, and a tripping current rating≤30mA.
3. Protection category for the parts in contact with electricity is I grade, Earthing wires should be
reliably connected to protective earthing conductors that are in accordance with the relevant
national security regulations.

Warning: The electric conductors are strictly prohibited to be connected with water supply pipes,
natural gas pipes and caliducts, otherwise, security accidents would be induced.
4. An equal-potential connection screw is foreseen on the back area of the machine. In case that
any other equipment inside the same room have equal-potential connections, the
equal-potential connection screw of this machine should be connected to an equal-potential
terminal of the other equipment through a copper conductor with a section area of no less
than 2mm2.
Ⅳ. Operation Procedure
1. Before operation, pour water into the water tank until the surface of water reaches a height
of 10cm.
2. Insert the three-pole power supply plug of the Awaken Fermenting Box into a proper socket,
and then turn on the circuit breaker in the power supply circuit, at this moment, the power
supply indicator lamp will light(red). Turn the temperature and humidity control knobs on the
control panel to desired position, and then, the temperature and humidity indicator lamps will
light(green), indicating that the Awaken Fermenting Box is in operation and is capable of
automatic operating within the setting range of temperature and humidity.
3. When the machine is out of operation, the power supply should be switched off so as to
insure your safety.
4. The machine is equipped with a water-lacking protection device. In case that the red power
supply indicator lamp is on and that the machine fails to operate even if the temperature and
humidity control knobs have been adjusted, please check for water level inside the water tank
and pour water into it until the water surface reaches a standard level, then, the machine will
be able to operate. In case that the machine still fails to operate, the power supply should be
switched off immediately and the machine needs to be inspected and repaired by professional
technicians.
Ⅴ. Attention and Maintenance
1. Regularly and often check the water level inside the water tank and insure that heating tubes
are dipped under the water surface so as to prevent the electro-thermal tubes from being
burned out. In case that these is no water inside the water tank, switching on the power
supply will be strictly prohibited so as to avoid any personal injury.
2. The awaken fermentation temperature is between 35℃~40℃, too high temperature will
influence the normal reproduction of the yeasts or even cause the death of them.
3. The waterproof category of the machine is of ordinary grade (IPXO), and therefore it is
suitable for indoor operation only. The machine is strictly prohibited to be placed at a place
where spraying water may possibly occur. Cleaning the machine with water spraying from a
pipe or by dipping it into water will be strictly forbidden.
4. The inside or outside area of the box body should be kept clean. The water in the water tank
should be replaced at least one time each day. The water tank should be kept in an condition
of cleanliness and sanitation. In case any dirt occurs on the surface of the machine, wipe and
clean it with a piece of cloth soaked in neutral cleanser solution. After the dirt has been
removed, wipe it with a piece of clean, wet cloth.
5. The connection mode of the power supply circuit is of X type. In case of replacing the power
supply wires, rubber sheath wires with specification similar to that of the wire type
Yzw1.5mm2that has been equipped for this machine must be adopted.
