2.2 Working Principle
Heat produced by energization of heating element(s) in the oil is transferred to the oil to
rise the temperature. When the oil temperature set point is reached, the thermostat will cut
off the power supply automatically and the heating element stops working. Once the
temperature drops a bit, the thermostat will connect the power automatically. The heating
element restarts working and the oil temperature rises. The procedure circulates to keep
the oil temperature constant within the set range.

4.3 Installation
1. The supply voltage should comply with the working voltage of the appliance. 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 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.
CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, CONNECT THE APPLIANCE TO A
BRANCH CIRCUIT WITH A 20 AMPERES OVERCURRENT PROTECTIVE DEVICE,
5. Working Instructions & Operation Flow
5.1 Operation
1. Check that whether the power installation is correct. Making sure that the supply
voltage complies with the working voltage of the appliance.
2. There are level notches on inner wall of tank. During using, keep the oil in proper
level. Users can regulate the oil capacity between “MIN”and “MAX”according to
actual requirement.
3. Power on, the green indicator illuminates, at this time, the appliance is energized.
Rotate the thermostat clockwise to make desired temperature value align with the red
dot, the yellow indicator illuminates, which indicates that the heating elements start
heating up the oil in tank.
4. When the set point is reached, the thermostat will cut off the power supply
automatically with the yellow indicator off. The heating elements stop working. Once
the temperature drops a bit, the thermostat will connect the power supply
automatically. The yellow indicator illuminates and the heating elements restart
working, the oil temperature rises. The procedure circulates to ensure the oil
temperature keep constant within the set range.
5. The cover is designed for tank cleaning and heat preservation. When covering, pay
attention that there should not be any water on the cover. Because, if the water drops
into the hot oil in tank, it may cause injuries due to splashing.
6. Equipped with dedicated baskets for smaller food. There is a hook and handle on the
basket. During operation, immerse the basket body into the oil. When the food is
cooked, lift up the basket and hang it to the slot up front the tank to drain off the
excessive oil. For larger food, put it directly into the tank to fry.
7. After working, turn the thermostat counterclockwise to limit position and cut off the
power supply to ensure safety.
8. To remove the used oil in tank, have the work done after the oil temperature cools
down to room temperature. First, cut off the power supply and take out the oil partition

in tank. Then, pull out the electrical box from the slot at rear of the bottom case. At
this moment, the heating elements are separated from the tank body completely with
the electrical box, put it on a clean area. Then lift out the tank for a thorough cleaning.
9. For safety and durability sake, users should remove the residues in tank and dirt on
heating elements regularly to keep the tank and elements in long-term clean state.
10. The oil partition in tank is designed for heating element protection. During frying, the
partition shall be put into the tank.
11. The electrical box is equipped with a thermal breaker, whose operating temperature
is 446℉(230℃) while the manual reset temperature is <330℉(165℃). Also, an
“overheat protection reset button”is provided at lower part of the box exterior. It
activates to protect the appliance once the oil is over-temperature. For reuse, press
the reset button to reset, only then can the appliance be used normally.12. There is a micro limit switch in the electrical box, which is connected when the box is
inserted into the slot in the bottom case, and disconnected while the box is lifted from
the slot.
13. Fresh vegetable oil (or pastry oil) should be used instead of used oil which may lower
the flash point and cause excessive ebullition.
5.2 Function:
Main function of the fryer is to fry food in a constant temperature. Cook temperature could
be set by the thermostat in according to food type with a range of 122℉(50℃) ～374℉
(190℃).
