• Operating condition for microwave oven with lower or higher wattage, may lead to slight
variations in cooking times.
• The operating conditions such as pressure reached inside the Microwave Pressure Cooker
and the cooking time, stated in the manual are for microwave oven of a rated power of
900 Watt.
• Always ensure the Microwave Pressure Cooker is properly closed before placing
into the microwave oven.
• Food items that tend to foam, froth and sputter may clog the safety devices. Some
examples are foods such as apples, cranberries, pearl barley, oatmeal and other cereals,
noodles, macaronis, spaghetti, rhubarb or split peas.
• Potatoes, vegetables, apples and eggs have to be pricked to prevent them from bursting
due to build up of steam pressure inside.
• When cooking doughy food, gently shake the cooker before opening the lid to avoid
ejection of food.
• Do not thicken when cooking under pressure.
• Move the Microwave Pressure Cooker, when under pressure with the greatest care.
• The Microwave Pressure Cooker may get warm, due to transfer of heat from the cooked

SAFETY FEATURES
1. All components of your Microwave Pressure Cooker have been manufactured with
microwave permeable materials which are food compatible. No metal parts are used in
the assembly. All components pass all the necessary global standards.
2. Your Microwave Pressure Cooker is perfectly safe to use.
3. Your cooker comes with four safety devices which combine to offer seven
safety features.
a. Primary safety device.
b. Secondary safety device.
c. Multifunctional Safety Lock (MFSL).
d. Mesh.
a. Primary Safety Device (Feature 1)
Your cooker is equipped with a primary safety device. This operates at about 4 Pounds/sq inch.
This may vary slightly depending on power of the microwave oven. As the pressure builds up inside
the cooker, after an initial emission of steam for a while, the Visual Pressure Indicator (VPI) will lift
up indicating the pressure build up. When the cooker reaches the designated pressure, the primary
safety device will release the steam. The primary safety device acts as both an excess pressure
releasing device and a pressure controlling device.
b. Secondary Safety Device (Feature 2)
Your cooker is equipped with a secondary safety device. When pressure starts building inside the
cooker, the secondary safety device is pushed up and will rise above the top surface of the lid. This
indicates that your cooker is under pressure. Similarly, after cooker is taken out from the microwave
oven, the secondary safety device will drop when the pressure inside the cooker drops to almost zero,
giving you indication that you can safely open the cooker. Please see User Instructions (Point 9) on
how to check if pressure has dropped to zero.
If the primary safety device fails to function due to overload or blockage, the pressure inside goes
above the normal level and the secondary safety device will operate at around 6.4 Pounds/ sq
inch allowing excess steam to escape. If this also gets clogged the secondary safety device is
pushed out by excess pressure and the hole is exposed rapidly diffusing the steam. This may be
accompanied by foaming / frothing on the nature of ingredients.
c. Multifunctional Safety Lock (MFSL) (Features 3 to 6)
This device enables user to operate the cooker in complete safety in multiple ways:
• When the cooker is properly closed the device securely locks the lid once internal pressure builds
up (Lock). (Features 3).
• The MFSL is also a Zero Pressure Device (ZPD). (Features 4).
• If the device is improperly closed, the MFSL will not allow internal pressure to build up.
• The MFSL Lock will release only if the pressure inside the cooker falls to almost zero, and only
then the cooker can be opened.
• The MFSL works as a visual pressure indicator, it lets the user know that the cooker is still under
pressure (VPI). (Features 5).
• The MFSL also allows the user to release pressure quickly (Quick Release System, or QRS).
(Feature 6).
d. Mesh (Feature 7)
This device ensures the primary safety device does not get clogged. This cooker will not build
pressure if the mesh is not firmly fitted into the cooker.

USER INSTRUCTIONS
1. Before you start using the cooker for the first time, check if all the parts are included and wash
all the parts with hot soapy water, rinse and dry thoroughly. Please check all parts are included.
Read Instructions.
2. Place the ingredients in the cooker with the correct amount of liquid as below. Examine lid to
check if all safety systems are clean and in place.
CONTENTS
Contents Cooker fill level not more than
Cereals and pulses, dried peas, beans, lentils, rice and pasta 1/3 full including liquid
Liquid foods, soups, stews 1/2 full including liquid
Solid foods, vegetables, one pot meal joints 2/3 full including liquid
Note:
a) If you overfill, the ingredients may touch the mesh assembly which may lead to
malfunctioning of the safety system. Ensure mesh assembly is firmly pressed in
position, and is not clogged.
b) The amount of water that is added for cooking in the Microwave Pressure Cooker
is important. If excess water is added for cooking, the Microwave Pressure Cooker is
so designed that the gasket may release the excess water inside the microwave oven.
While this is not dangerous, it still will make a mess inside the microwave oven.
If the recipe calls for excess water like soups, it is advisable to cook with less water in
the Microwave Pressure Cooker and add the water subsequently.
3. Place the gasket in position. Ensure that the cavity below MFSL cover is clean and press the
cover in position. Ensure that the VPI is free to rise through the hole in the cover. Close the lid
by aligning the arrows on the lid opening / closing aid and body opening / closing aid, turn the
lid clockwise until the lid opening / closing aid comes above the body opening / closing aid.
See Fig A below. Ensure the splash guard is pressed firmly in position.
4. Set the cooking time as desired. When cooking for the first time always under estimate the
cooking time. If the food is not cooked as per your requirement, increase the time until food is
cooked to your satisfaction.
Add water for extra cooking times, this will vary from 0.51 ounces (15ml) to 0.68 ounces (20ml)
per minute of extra cooking time, depending on power rating of the microwave oven.
5. The secondary safety device rises when the cooker develops pressure. When the cooker is fully
pressurised, the primary safety device releases pressure gently. This action is normal and allows
excess steam to escape. You may also hear hissing sound, which is normal.
8
6. After the set time is over, and the microwave oven beeps, wait before opening the microwave
oven door as per manufacturer ’s instructions.
7. The Microwave Pressure Cooker becomes warm during cooking due to heat being transferred
from the food. Always use pot holder / gloves / mittens to remove the cooker from your
microwave oven. See Fig B.
8. It is safe to open the lid, after the MFSL VPI drops. Do not attempt to open the cooker until VPI
drops. If VPI has not dropped down after 2-3 minutes, used a spoon to press the VPI down. If the
VPI pops up again, repeat the procedure after waiting for more time. See Fig C.
9. Turn the lid anticlockwise using the opening / closing aids and lift the lid off the body. See Fig D.
10. Check if the food is cooked to your satisfaction. If not follow instructions given above
adding water as per the table.
11. If your recipe calls for addition of more ingredients / stirring, and further cooking,
follow instructions given above.
12. For steaming food, you can remove the mesh.

WHY USE A MICROWAVE PRESSURE COOKER?
When cooking food on the hob, in the oven or microwave, water boils at 100°C/212°F and will stay at
this temperature during the cooking process. This is because the lids of normal pans allow steam to
escape. If a tight seal is formed then pressure inside a pan is increased and the contents will actually
reach higher temperatures and consequently cook food much faster.
The Microwave Pressure Cooker is a sealed vessel that does not permit air or liquids to escape
during cooking until the designated internal pressure is reached, allowing temperatures to rise above
100°C/212°F. During cooking, the pressurised steam inside keeps the lid tightly in place, preventing
accidental removal. Flavours are sealed in by the pressure and shorter cooking times. With less liquid
to heat and higher cooking temperatures, cooking times are much faster and energy savings are
therefore considerable. It’s also possible to cook several foods together, adding those that require
less time later in the cooking process. A steamer basket is included to allow foods to be layered yet
kept separate. You can even cook a savoury dish and steam a pudding at the same time! However, the
Microwave Pressure Cooker should never be filled to more than two thirds its height with solid food or
a third full with foods that foam and froth eg. rice, dried beans, pasta etc. A tablespoon of cooking oil
can be added to minimise foaming.
As the food is cooked at above 100°C/212°F, bacteria and viruses are killed, and heat is very evenly
and quickly distributed meaning no hot or cold spots. Unlike conventional microwave cooking,
standing time and stirring is not required.
In the Microwave Pressure Cooker, it is not necessary to immerse foods in water as one would do
when boiling on the hob. Only enough water (or other cooking liquid) as outlined in the recipes on the
following pages is required. This means that it is a healthy way to cook as vitamins and minerals are
not dissolved so readily by the water. Never be tempted to use less liquid than indicated though and
never use oil in place of water.
TIPS AND SUGGESTIONS
• Pressure cooking in a microwave is a new and unique method of cooking. You will enjoy the speed
of a microwave without the rubbery textures you may associate with microwave cooking. The
following recipes were developed using a 900W microwave. Microwave wattages vary greatly.
Please check your wattage prior to use. Cooking times will need to be adjusted slightly depending
on the wattage of your microwave.
• While not essential, searing or browning meats on the stove top in a skillet prior to
pressure cooking adds flavour to your dishes that can’t be duplicated with spices. It’s well worth
the extra step.
• Some sauces benefit from being thickened after the cooking process in the microwave is complete.
This can be done by stirring a slurry (water and cornflour) into the hot cooking liquid. This is a
simple process and will result in a richer sauce that more evenly coats the food. Combine two
tablespoons of cold water and two tablespoons of cornflour. Mix well and add to the hot cooking
liquid sauce. Stir until well incorporated. If the sauce does not thicken right away, put the cooker
back in the microwave for thirty seconds to re-heat the sauce and stir again.
NOTE: If the slurry is too thick just add an extra teaspoon of water until it is loose enough to pour in.
