During the conveyance of the machine, the vibration will cause the loose or removal of the spare parts, so when
installation and debugging, please tighten each loosening parts.

Pour oil before heating, and its oil level can’t be lower or higher than the oil level line. It is forbidden to heat if there
is no oil in the boiler, otherwise the electro thermal pipe will be burned out.

The temperature is set between 150℃and 180℃, the user can set it depending on the production, timing set, cold oil
to heat for 20 to 30 min, hot oil to fry 10 to 15 min, before frying the food, the oil temperature must be over 150℃.

When cold oil heating, you’d better not lid the cover. Mix up manually the oil continuously to heat it fast and
well-proportioned.

When its delivery, the pressure of the automatic overflow valve is usually set at 0.07Mpa to 0.08KPa, if the
indication of the pressure gauge exceeds 0.09MPa and continues to increase, discharge the air manually, and unbolt
moderately the air-release valve to discharge the air, making the air pressure keep at 0.08Mpa to 0.09Mpa.

III. Operation Principle and Process
Preparation before starting the machine and the process for frying

Before you turn on the ON/OFF switch , you must open the fryer lid to pou r at least 25L oil into the pot. (When you
pouring the oil, looking at the oil line===, to make sure it is suitable to be higher 10mm than the heaters).Be careful,
before you pouring the oil into the pot, you should open the door at the bottom side to check the oil drain valve and
oil filter valve to make sure that it is in be closed. After checking this, close the door at the bottom to connect the
power to start the machine. Open the power supply switch---, the PV(℃.) on the controlling panel shows the oil
temperature in the pot.

SV shows the temperature you set. The four figure that showing in the right side is the time for minutes and seconds.
In ordinary use of the machine , the time and the temperature is set just according to the users. The machine is
equipped with 1-0 ten store key , 10 store key in total, it is used for the frying of ten different foods. The steps of
setting is as follows: first, press the key of ①, then press the temperature key, then press the ▲▼UP DOWN key to
set the temperature you want( attention: the best temperature for frying chicken is 165℃.). Second, press the Time
key, now the timing display is shining now, then press the ▲▼UP DOWN key to set the time, the time you set is the
minutes( the time for frying chicken is 10 min), the last two figure is second. When the minutes is set ok, press the
TEMPE to set the second, second can be set as 00.Then you press the ① for at least time seconds, at this time, the
TEMPE key will shining for three times, the loosen the key , then it is ok for the setting of the 1 key, the setting steps

of 2-0 key is the same like this.

After setting, it is the time for you to fry the foods. Press the COOK key , the electric circuit is connected now, the
temperature is increasing normally to cook the oil in the pot. You’d better not closed the fryer lid when the
temperature is not up tp the working temperature. While preheating, use the handle of the basket to mix the oil to
make sure it is heated equally. After preheating, (means up to the setting temperature), press the ON/OFF key, now
you can put the prepared food into the basket( the machine is equipped with one basket), using the handle of the
basket to lift the basket to the fry pot, then take the handle of the basket away and closed the fryer lid, make the
pothook ok, then tighten the threaded rod. Then press the ON/OFF key, the control display is working now. The
temperature is arising and the time display is shining, and it begin to timing now. As the temperature is up to the
setting temperature, the heater in the pot stops heating. When the temperature is lower than the setting temperature,
the heater will automatically heat again. As the time going to “0”, the Exhaust valve will be automatically open to
exhaust. The process of frying is ok. As the steam in the pot is exhausting ok, means the pressure gauge shows”0”,
you can loosen the threaded rod. The press the beam, using the handle of the basket to lift the basket, waiting for few
minutes you can take the basket away from the fry pot.

Fastening method of opening and clos ing the cover:
Lay down the lid, trying our best to press the down plank to make sure the lid is closed well. Open the hook lock to
ensure that it is fasten well with the frontage of the pot. Spinning the spindle in the clockwise direction, press hardly
to make sure the make sure that the red or the black ball is in the same direction with the hook lock. Loosen the
spindle in the counterclockwise direction when you open the lid, press the (A) and try to open the hooklock..
Preheating and the treatment of raw oil

The universal vegetable oils (except peanut oil) can’t be edible until fried well, otherwise there will be a smell of raw
oil, so you should preheat the oil each time you pour new oil and you pour oil (cold) for the first time for frying. The
method: temperature 140℃ to160℃, time 10-20 min (it depends), making the raw oil in the boiler bubble up.
Additionally, for this preheating and the treatment of raw oil, there is no food to fry in the boiler, that is, there is no
vapor, no pressure indication for the pressure gauge, so please pay special attention to the heating time and
temperature, it is best for you to open the cover..

Operation process of cooking and frying
After heated as the above methods , reset the working temperature and time, put the prepared food in the frying
basket, put the frying basket in the fry pot with a special “handle” fast and balanced, lid the cover quickly, make the
cover balanced, fasten the fastening screws, screw them with proper strength, and confirm the air-release valve is
closed. At this moment, the pressure indication of the pressure gauge shall increase slowly. When the pressure
reaches 0.07Mpa to0.08Mpa, the overflow valve starts to discharge the air automatically, making the air pressure
keep invariant. When the temperature reaches the invariant value, the time reaches the set value, it will release the air
automatically.. When the air in the boiled is discharged completely and the pressure gauge indicates “0”, loosen the
fastening screw, press down the crossbeam with hand, loosen the crossbeam hook, and open the cover, otherwise
there will be a danger. When opening the cover, the operator should be stand side face, in case the hot air shall emit
to scald his wrist. The operator must have a good knowledge of how to operate the machine to ensure the security.

The workers are forbidden to leave the working scene, they should supervise the production process, if any abnormal
situation, stop the machine immediately, find out the cause, and operate again after the troubles are got rid of.

Method of oil filtering
Open the fryer lid, taking the basket out of the pot. Use a knife or some other tools, like the handle of the basket to
remove the residue left to the inside of the pot. Open the vent valve, pou rin g th e oil in to the oil pot. If the oil drainage
hole is not unobstructed or it is jammed, you can use brush or some other tools to clean up the oil drainage hole to
avoid jamming. (Attention, do not use some metal tools that are to hard). When filtering the oil, using the brush to
clean up the residue in the pot and fully filtering the oil in the pot. Close the lid of the machine to avoid the splash of
the oil and turn off the vent valve. As soon as you make the oil strainer, fabric and connector ok, you can open the
Filter Valve and press the power switch down side to start the oil pump, the oil is pullback to the pot of the machine.
At this time, the residue in the oil is left in the oil cylinder. After filtering the oil, turning off the Filter Valve, then to
make the power switch (functional switch ) to the position “0”. Remove the connector for the oil filtering, cleaning
up the oil cylinder and change the oil filter bag.

Safety Points for Attention
 In order to protect people from hurt, the machine can not be used if a grounding device is not equipped. (use

2.5mm2 cuprum wire to contact with the ground bolt)

 Don’t start to heat when there is no oil in frypot or the oil lever lower than element, otherwise the elements will

be burn. Please don’t wash the heating ele ment by cool water until they are cooling, or it will explode

 Latch the lid before heating. Don’t operate the securing hook and draining the oil. Befor e you open th e fryer lid ,

to make sure the there is no pressure in the frypot, that means the pressure gauge shows “0”. After 30 second,
you can open the fryer lid to avoid explosion for the pressure.

 In order to keep the good sealing betw een fryer pot and fryer lid, do not u se handle or some other h ard tools to

strike the fryer lid and mouth of fryer.

 The rubb er seal of the fryer lid can not be dismantled of yourself. For it may effect the sealing. While it is not

working, you should close the fryer lid, but not too tight to avoid the aging of the seals.

 You should cut off the power if the machine is not working in order to avoid explosion for the wrong operation.

Maintenance and Upkeep of the Machine
Clean the overflow valve twice weekly, screw the screw lid, and clean the gravity block, making it jump freely and
open and close flexibly. Check the general electricity and screws of power line, and joints monthly. If any loose,
fasten them to make them contact well and control sensitively.

Clean the smear away from the electro thermal pipe in the boiler and cabinet after daily work is over to keep clean
and sanitary and enhance the use life span of the machine.

After a relatively long time use, the rubber gasket shall be replaced in time if it is found aging and ineffective.
Loosen the glue bar fastening screws of four sides on the cover, take out the glue bar from the groove slowly, put new
sealing rings into the groove, and fasten the screws.
