q）Please keep this manual properly.

1、The pressure cooker is a family cookware and can not be used for any other
purpose. Juveniles and persons who don’t know how to use it are suggested not
to use. Must have person watching and keep away from children when using the
pressure cooker.
2、Under the pressure limit, the boiling point of the liquid is below 120ºC (250F).
Please operate carefully because a lot of steam and soup juice will come out
when boiling and especially when the pressure reducing fast.(Fig.2)
3、Do not cook expansive food such as apple jam, seaweed, oatmeal, etc. to
avoid blocking of the steam-releasing hole.
4、Keep the pressure-limiting valve, Safely open-preventing valve, sealing ring,
block-preventing cap, lid and cooker body clean and out of nastiness and
greasiness before and after using.
5、The pressure cooker should be used on a steady
oven. Do not put the pressure cooker on electric
oven that has a bigger plate’s diameter than the
cooker’s bottom. When cooking on a gas oven, the
fire shall not reach the cooker’s wall. The pressure
cooker is applicable to 2KW oven.

Fig.2

6、Do not point the safety window to the user or to
the area person often walk about.
7、If steam sprays out from safely open-preventing valve , or the sealing ring is
squeezed out from the safety window, the power shall be shut off immediately.
The problem must be found out and solved before use again.
8、Be very carefully when you moving the cooker with pressure. Carry it
horizontally and lay down gently. Do not bump.
9、Do not open the cooker when there is pressure inside. Do not cook in case of
the lid is not closed well.
10、Do not store salt, soy sauce, alkali, sugar, vinegar, or steam water inside the
cooker for a long time. Clean and dry it every time after use.
11、Do not heat water off or dry heating. Not use for frying or baking food.
12、When cooking jelly-liked food with pressure cooker, shake lightly for
several times before open to avoid food spay out.

Ⅲ、Safety of products

※ We designed and equipped multi-device for safety.(Fig.6)

1、The block-preventing cap and dredging needle are to be used for

preventing blocking of the pressure-limiting valve.

2、The open-preventing device ensures the lid to be closed properly as well

as safely.

3、The three-degree pressure release device ensures using safely.

1).Pressure regulator: If pressure inside is up to a regular working range, the

Fig.6

7

pressure regulator will release extra steam. Ⅰworking pressure is 60kpa, Ⅱworking

pressure is

110kpa.

2).Safety open-preventing valve: it will raise when the pressure up to 4Kpa.
Ensure steam releasing from here under safety pressure when steam-releasing
hole is blocking.

3).Second safety valve: When the pressure regulator and the safety valve are
invalid, the steam will release from releasing hole of second safety valve to
ensure using safely.

4).Opening push button:

Open the lid must push the button.

Ⅳ、Special characters.

ⅠThe composed bottom of the cooker is made by friction pressure

machine, which makes it strong and reliable, and without any chink.

ⅡThe diameter of composed bottom is bigger than common products,

which makes cooker absorb heat faster.

Ⅲ Setting adjustable press-limiting valve which for users to choose

whatever pressure he may use（Fig7）.

IV Setting pressure indicator, it will be easy to know the pressure inside

and set user’s heart at rest.（Fig.8-10）.Equipping special pressure-limiting
installation without long steam –releasing pip system, keep the food delicious,
make sure working is normal and not block. The reason of block is
steam-releasing pip too long.

Different position of the pressure regulator, different function.※

Position for releasing the pressure

Low pressure（60Kpa）

High pressure (100Kpa)

Fig.7

Fig.10 Fig.9 Fig.8

※ When the first line goes up, it means that the working pressure is at the

low status（Fig .8）；
When the second line goes up, it means that the working pressure is at
the high status（Fig.9）；
When the third line goes up, it means that the working pressure is
abnormal（Fig.10）.
There are two possibilities if it is abnormal:
A、The fire is too strong,turn down the fire.
B、Check whether the pressure regulator is obstructed or isn’t fixed

properly.

Ⅴ、How to use

※ Please clean the pressure cooker before first time using.

1、Making sure that the steam-releasing hole is unobstructed

Make sure that the safely open-preventing valve hole and the
steam-releasing valve hole is not obstructed every time before using. If any of
them is obstructed, clear away the dirt with the dredging needle.

2、Closing the cooke

Align the mark “O” on the lid to the mark “O” on the lower handle to close
the cooker properly before heating. （Fig.11）

3、Adjusting working pressure.

Closing the lid, according to requirement, please reference section IX.

4、Heating

In order to raise the temperature quickly, heat with strong fire till the
pressure-limiting valve begins to work. Pay attention not to using stronger fire
than which is enough. It is normal that a little steam seeps from the safely
open-preventing valve after heating for a while. There should be no steam seeps
after the open-preventing valve rises and the cooker works normally. When the
pressure-limiting valve raised and steam comes out continuously, should use
gentle fire and start to count heating time.

Caution: Heating time is from the pressure-limiting valve starting to
work to turning off the fire.

※ Stand by and watching while cooking.

※ Do not touch the cooker’s metal surface with hands or body. Cook

carefully and use the handles to avoid a burn.

5、Turning off fire, releasing pressure and opening the cooker

Two open ways after cooking.

○

1 Natural cold. When heating time is up, turn off the fire and leave it for a
while waiting for the pressure reduced. Take off the lid when the safely
open-preventing valve fell down. The opening procedure is contrary to the
closing. Push the opening button back and make it on estate of opening when
you open the lid. Contrarotate upper handle to align the mark “O” on the lid to
and the mark “O” on the lower handle to open the lid. (Fig.12)

Fig.12

10

◆ Don’t push the button till the safety valve falls down.

◆ When cook pasty state food such as porridge, shake the cooker slightly

before open to reduce the bleb.

○

2 Cooling down quickly. Sometimes it needs cooling down quickly, put

the cooker on a level place and shower the cooker with cold water slowly till
the safety valve falls down (Fig.13)

Fig.13

Caution: Avoid water flowing into the cooker through safely
open-preventing valve and the pressure limiting.

Note: Push the button to open lid, then the button naturally stays a
ready-to-close place. If the button goes back, you should push it forward.
Otherwise the lid won’t be normally closed.

Ⅵ、Trouble shooting

If any abnormal phenomenon been found, you shall turn off the fire
immediately and take the cooker to a level place and shower the cooker with
water slowly to reduce the temperature and the pressure. Find the reason and

Caution: Do not lose small parts such as pressure-limiting valve. There
is no problem if the color of the sealing ring changed. It is suggested to
change the sealing ring once in on or two years according the usage
frequency. But it must be changed immediately if there is any damage or
shape changing. Please contact your dealer or the sales department of our
company for the replacement parts. Never use substitutes.

Ⅷ.Questions and Answers

1. Q: How to cook good meals and dishes?

A: Heating the cooker with strong fire till steam sprays out from

ressure-limiting valve.

Change the fire from strong to gentle when steam starts to spray out from
pressure-limiting valve.

Let the pressure inside the cooker reduce naturally.
Too strong fire will make water over-evaporate and cause burnt to the
food inside the cooker.

2. Q: Cannot do cooking well?

A: Check if the cooking time is controlled properly or not.

Check if the pressure-limiting valve is placed properly or not.

Check if the heating fire is too strong or too weak.
Check if the volume of water and soup is proper or not.
Check if the pressure is normal or not. (Is there any steam spraying out

from pressure-limiting valve or not.)

14

3. Q: What is heating time

A:Begin from the upspring of the steam spraying out from safely

pressure-limiting valve.

4. Q: Does different mat erial need different heating time?
A: The maximum volume of the food to be cooked is below 2/3 of the depth

of the cooker. Beans are below 1/4. Cooking material has nothing to do with
cooking time. Besides, the volume of the cooker has nothing to do with cooking
time, either.

5. Q: Why the rice color changes to grey?

A: Cooking under high temperature and high pressure, the amino acid and

saccharides are decomposed by the heat. Thus the food containing rich protein
and carbohydrate may change its color to grey. But it is harmless and the tast e
will not change.

After heating, soya-bean milk mixed with sugar sprays out from the safety valve.

When heating, liquid food mixed with high-thick sugar will spray out from

the safety valve because of the high pressure steam inside the cooker.

When cooking this kind of food, don’t cook with pressure on, which means not to

place the pressure-limiting valve on.

6. Q: What to do in case of cooker is heated dry.

A: Put off the fire immediately, take the cooker away from the fire and let it cool

naturally . Don’t pour water onto the cooker.
