4.3 Installation
1. The supply voltage should comply with the working voltage of the appliance. The
appliance is equipped with copper equipotential terminals at lower back of the box,
which should be connected with copper wire no less than 1.5mm²reliably as
prescribed. After installation, check that whether the connection is loose, whether the
voltage is normal and whether the safety grounding is reliable. The fixed arrangement
of wire should be equipped with an all-pole disconnecting switch with a contact
opening of at least 3mm on its poles. It is advisable to install a grounding leakage
protection switch or relay that with a leakage peak of 10mA. Mounting space for the
device shall be at least: 1500 ×850 ×530 mm (L ×W ×H). Unpack the device and
place it on the floor.
Accessories Installation:
1. Have the appliance unpacked and take out the following accessories: food tray
(bottom) (1), food tray (back) (1), lead-in rack (1), adjustable leg (4).
2. First, screw the four adjustable legs into the screw holes at bottom in right rotation.
Then, put them onto the operating platform with proper height. For safe operation
sake, please level the machine by adjusting the adjustable legs.
3. Insert the hooks on both ends of the lead-in rack into the mounting holes, as indicated

5. Working Instructions & Operation Flow
1. Before using, check that the power installation is correct. Making sure that the supply
voltage complies with the working voltage of the appliance.
2. Power on, the indicator illuminates. Rotate the speed regulator (COLOUR CONTROL)
to “3”position. (Note: The lighter the color is, the faster the conveyor speed is.)
Rotate the level governor to “BREAD”position, at this time, top and bottom heating
elements start working simultaneously, the chamber temperature rises gradually. If
the chamber is unloaded with bread, it can be up to 284℃at midpoint in 12min. Then,
it will keep constant at 284℃.
3. Before baking, please energize the appliance and preheat for about 10-12min. Then,
try baking with two pieces of bread to see the color degree so as to adjust the
conveyor speed. To bake bread with deeper color, turn the knob clockwise from the
color circle with deeper color to position whose scale is larger than “3”. (Note: The
deeper the color of color circle and the larger the scale value is, the slower the
conveyor moving speed and the deeper the bread color is, and vice versa.) After the
conveyor speed is adjusted, put the bread onto the conveyor via lead-in rack, the
bread will be passed into the toaster to bake with the movement of conveyor.
4. The cooked bread will be delivered to the food tray at bottom and slide out to the front
from the chamber bottom, as shown in Fig. 4.
5. To collect the bread at back, the appliance is equipped with a food tray at back. Press
down the back slide board with lugs at rear of the furnace body to make the front end
of the slide board have contact with the pin near the chain wheel. The cooked bread
will slide to the back food tray along with the slide board, as shown in Fig. 5. When
the work is done, hold the lugs to pull up the slide board to reset.
6. To bake buns, rotate the level governor to “BUNS”position, at this time, only top
heating element works. If warming is needed, rotate the knob to “STBY”position.
7. When the work is done, turn the level governor to “OFF”position and unplug.
8. To avoid appliance contamination and performance damage, do not use this
appliance to bake food whose surface has too much sugar or sticky food that will flow
out after heating.
9. If the power cord is damaged, substitute with dedicated or specialized component
bought from the manufacturer or its maintenance department. Substitution should be
done by professional personnel.
