1. The benefits of vacuum low temperature cooking
Using vacuum low-temperature cooking, the food does not need to be in di-
rect contact with air and water, which will reduce the loss of nutrients in the
food, infiltration of harmful substances, using no oil or using very little oil,
and consuming a small amount of salt to preserve the taste of the ingredients
themselves. The food maintains a good taste, and even ordinary meat can
greatly enhance the taste.
The heat is more even, the taste can penetrate into the food evenly, and the
color of the food can be preserved; the energy is saved compared with the
oven and the gas stove, and the smoke pollution of the kitchen can be reduced,
different food can be cooked separately by packaging.
You don't need a special chef, even if you don't have any cooking experience,
you can cook healthy and delicious food according to the scientific recipe. You
can cook according to the set temperature and time by vacuuming the food
according to the recipe.
Thanks to precise temperature and time control, it is possible to ensure that
food not scorched or dried out due to overcooking, especially for food cooked
at medium and low temperatures.
2. Preparation for vacuum low temperature cooking
• Vacuum sealing machine – To remove most of the oxygen from the bags
and to ensure an air-tight seal, preventing air or liquid going in. You can
use chamber vacuum sealer or small suction vacuum sealer for different
demands. We supply both kinds of vacuum sealers.
• Vacuum sealing bags – To pack foods in and thoroughly sealed, ensuring that
no air or liquid can go inside. Please also ensure that the vacuum sealing
bags can bear temperatures up to 100°C or 212°F.
• Thermal Circulator with Cooking water tank or Sous Vide water bath – firstly
put the cooking rack into the water tank (Not using the cooking rack might
result in a machine break down), then fill the tank or water bath with enough
water to cover the foods and control temperature for cooking. For immersion
thermal circulator, please also ensure that the water tank can bear tempera-
ture up to 100°C or 212°F. For Sous Vide water bath, there is a thermostat
controller inside the machine. So please fill water into the bath then control
the temperature and time.

place out of the children’s contact.
Note:
1. Before Sous Vide cooking, the food must be vacuum packed first.
2. The water level (after the food is put in) should be higher than the ”MIN”,
but lower than the ”MAX” marked on the machine.
3. To avoid the machine from aging, drain the water after use and clean the
water bath.
9. Maintenance
To avoid burning, please make sure that the machine is power off and cool
down to room temperature before cleaning.
1. Place the machine vertically after cleaning, do not place it horizontally or
upside down.
2. During cleaning, do not damage the components inside the machine. Once
the components are damaged, please ask specialist to check and repair. Do
not attempt unauthorized repairs to avoid accidents.
3. Abandon old water after each use, and fill with fresh water next time. If the
water is reused many times, some mineral substance may subside or adhere
to the surface of the components, thus influence the machine performance.
When you notice the discharge capacity reduce obviously or the machine’s
components have much ash and dirts, Please disassemble the low part
of the machine’s housing(Please refer to the below ”How to Disassemble
Quickly”) to clean the heat tube and probe , it is better to clean every 20
times or 100 hours working.

10
How to Disassemble Quickly
a) Use the tool to remove screw. b) Pull out the low part housing to
clean the inner components.
4. Better not use hot machine in cool water. It should be cool down the ma-
chine to room temperature and put into cool water to use. Otherwise it will
influence the machine function and lifetime. On the contrary, please do not
put cool down machine into hot water to use.
10. How to Clean
Preparation:
Food grade vinegar (white vinegar, apple vinegar, etc.)
Why need to clean:
Normally tap-water contains minerals in our life. When the water is heated
to a certain temperature, there will be scale on the heater or surface of the
machine. In this case, the scale will affect the performance of the machine,
and the machine is not good in outlook as well. So we suggest you cleaning
the machine after every 20 times use, and accumulated working time is less
than 200 hours. Or you can clean the machine according to your actual needs
due to different water in different place.

11
How to clean:
1. Use the mixed liquid in 75% water and 25% vinegar, them pour it into a con-
tainer till the Max line of the machine.
2. Turn on the machine, set the working temperature 80°C/(176°F) and set
the time 3 hours (03:00), then single press the ”Start/Stop”. When reach the
desired presetting temperature, press ”Start/Stop” to start the timer.
3. When the timer indicates 00:00, stop the machine and turn off the power,
unplug and let the machine cool.
4. Drain out the water from the container and use the fresh water to clean the
device.
