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.
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.

Operation, Repair and Maintenance
1. Switch on the power suppy, turn the“operation”switch on the panel to the “ON”position,
Adjust the tempetature controllers for“upper temperature”and the “bottom
temperature.”to the desired value, then the baking oven will begin operation, the green
indicator lamps on the temperature controllers will be on. In case that the temperature
reach the set value, the green indicator lamps will be off, indicating that the exothermic
tubes stop heating and get into a constant temperature state, then, the temperatures will
be automatically adjusted according to the set temperatures.
2. The users can adjust the bottom temperature as per baking requirements for different food
so that the ideal color and luster of roasted food could be achieved.
3. Lighting devices equipped for the baking oven will facilitate taking an observation on the
oven’s interior situation.
4. When the baking work is finished, turn the“operation”switch on the panel to the
“OFF”position, then switch off the power supply.

Product Instruction for Proofer
Brief Introduction
Proofers 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
mould 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.

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
User Manual
7
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.
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.
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
User Manual

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
Yzw1.5mm2 that has been equipped for this machine must be adopted.
