THE STRUCTURE DRAWING AND THE MODEL OF PRODUCTS

ATTENTION POINTS OF OPERATION

• Use only after reading and understanding all about the manual.
• Please keep this manual properly.
• Warning, the user will take responsibility when an accident occurs due to the operation not following the manual.

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 the 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 a 2KW oven.
6. Do not point the safety window to the user or to the area person often walkabout.
7. If steam sprays out from a 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 careful when you move 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 a pressure cooker, shake lightly for several times before opening to avoid food spaying out.
13. Allowed volume of food inside the pressure cooker.
    • Less than 2/3 of the cooker height for non-expansive food such as meat, vegetable, etc.(Fig.3)
    • Less than 1/4 of the cooker height for expansive food such as rice, bean, etc.(Fig.4)
14. It is prohibited to put anything on the pressure-limiting valve.(Fig.5)

SAFETY OF PRODUCT

We designed and equipped a 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 use safely.

SPECIAL CHARACTERS

1. The composed bottom of the cooker is made by friction pressure machine, which makes it strong and reliable, and without any chink.
2. The diameter of composed bottom is bigger than common products, which makes cooker absorb heat faster.

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

3. 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.

4. Turning off fire, releasing pressure and opening the cooke r
   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. (Fig.7)
   Caution: Shake the cooker gently before opening to eliminate the foam inside the cooker when cooking sticky food.

5. Cooling down quickly
   Sometimes it needs cooling down quickly when cooking over time, or preventing cook over time, or the cooker needs to be opened during cooking. Put the cooker on a level place and shower the cooker with cold water slowly till the safely open-preventing valve falls down. (Fig.8)
   Caution: Avoid water flowing into the cooker through the safely open- preventing valve.

Please contact your dealer or the sales department of our company for the replacement parts. Never use substitutes.

QUESTIONS AND ANSWERS

1. Q: How to cook good meals and dishes?
   A: Heating the cooker with strong fire till steam sprays out from the pressure-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 the pressure-limiting valve or not.)
   

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 materials 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 taste 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 the 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.
