IMPORTANT SAFEGUARDS
To reduce the risk of personal injury or property damage when using this appliance, basic safety precautions should always be
followed,including the following. You can get total satisfaction from your Manttra Smart pressure cooker if you follow the simple
instructions given below:
1. Read all instructions. In particular, remember to follow the safety precautions. Please do not tamper with the safety devices.
2. When using this appliance near children, it is necessary to keep a close watch.
3. Do not place dry / empty appliance on a heat source. Always use sufficient quantity of water, else, this will seriously damage the
appliance and also lead to fusing of safety
device.
4. Move the pressure cooker/pressure pan under pressure with greatest care. Do not touch hot surfaces. Use handles/knobs. If
necessary use gloves.
5. Do not use this appliance for other than intended use.
6. This appliance cooks under pressure. Improper use may result in scalding injury. Make sure that the cooker is properly closed
before operating. See the “Instructions for use”
7. Do not fill the cooker/pan more than two thirds capacity. For solids like rice, meat and vegetables, which expand during cooking
do not fill the unit over half full. Over filling may cause a risk of clogging the vent tube and developing excess pressure.
8. Do not open the cooker until the pressure has been reduced to zero. While there is still pressure in the cooker, do not remove the
pressure regulator. The Visual Pressure Indicator (VPI) provided in your cooker will indicate that the pressure has dropped to
“zero” (refer page 7). Only if no steam escapes, and the VPI drops below the surface of the lid handle, can the open-close knob
be turned and held to “open” position for opening the lid. The lid should, under no circumstances be forced open.
9. Please avoid direct cooking of foods that tend to foam, froth or sputter. They may block the vent tube.

10. Do not release the pressure quickly when cooking rice, dal as the liquid inside may froth over.
11. Be aware that certain foods such as applesauce, cranberries, pearl barley, oat meal or other cereals, split peas, or foods such as
noodles, macaroni, rhubarb or spaghetti can foam, froth and sputter and may block vent tube. These foods should not be cooked
in pressure cooker/pressure pan
12. Always make sure that the vent tube is clear before closing the lid for pressure cooking.
13. Do not use the body of the cooker for deep frying.
14. Do not use the pressure cooker/pressure pan for pressure frying with oil.
15. Never use the Quick Release System (QRS) for steam release in case of liquid or frothing foods.
16. Always make sure that the Zero Pressure Device (ZPD) and the space around the ZPD inside the lid is kept clean. Otherwise the
ZPD will not seal properly to build up pressure.
17. For proper closure, lid handle must be directly above the body handle with the lid handle stopper engaged in the body handle
slot, when the open-close knob will turn to “close” position.
18. For safe pressure cooking, we advise you to replace the ZPD once a year otherwise it may not function at the time of need and
may cause damage .
19. Extreme caution must be used when moving this appliance containing hot liquids.
20. Never place anything over the pressure regulator as the pressure regulator may not work at the desired pressure.
21. Always buy genuine Manttra spare parts. Use of duplicate parts may cause damage to the appliance. Write to Manttra Inc. for
spares.
22. When the normal operating pressure is reached, turn the heat down, so all the liquid which creates the steam, does not evoperate.
23. After cooking meat with skin (example: Ox tongue) which may swell under the effect of pressure, do not prick the meat while
the skin is swollen. You might get scalded.
24. Do not change the pressure settings, when the cooker is in use or while there is pressure inside the cooker.

INTRODUCTION
MANTTRA SMART PRESSURE COOKER is brought to you by MANTTRA INC.
PRINCIPLE OF PRESSURE COOKING:
Under normal circumstances, most foods cook at 2120F ( 1000 C). This is because the water boils at this temperature
in normal atmospheric pressure.
If the temperature of cooking is raised, foods cook much faster. For example, an increase of 320F (180C)
temperature allows food to be cooked four times faster, retaining freshness and nutritional values of the food.
By increasing the steam pressure inside a pressure cooker to 12 lbs per square inch above the atmospheric
pressure, the temperature inside the pressure cooker increases by 320F (180C) roughly. Thus, at these higher
temperatures food cooks much faster.
This is the principle of pressure cooking.

DESCRIPTION OF PARTS
Note: Due to continuing improvment, actual parts in your cooker may differ slightly from the illustration
above. Optional items may not be available in some models.

SAFETY FEATURES
Your Smart Pressure Cooker comes with 7 safety
features:
a. Zero Pressure Device (ZPD)
b. The Pressure Regulator
c. The Gasket Release System (GRS)
d. Fusible Safety Device
e. Quick Steam Release
f. Visual Pressure Indicator (VPI)
g. Auto-Lock
a. Zero Pressure Device (ZPD)
For your safety, your Smart pressure
cooker has a Zero Pressure Device
(ZPD) on the lid, housed under the lid
handle.
The ZPD will allow the cooker to build up pressure
only when the cooker is completely closed when the
“open-close” knob turns to “Close” position. Similarly
the cooker will not open unless the pressure drops to
Zero and the “open-close” knob is aligned with the
“Open” position
b. The Pressure Regulator
This appliance is equipped with a 3
stage pressure regulator which is the
first safety device. This operates at two
pressure settings at 8 lbs. per sq. inch
and at 12 lbs. per sq. inch with the Quick
Release System (QRS) feature. If you want to cook at
lower pressure (8 psi) align the tang of the pressure
regulator to the notch on the cup in the lid handle
marked by “I” (a single line) and for cooking at higher
pressure (12 psi) align the tang to the notch on the cup
in the lid handle marked by “II” (two lines). When the
cooker reaches the set pressure the pressure regulator
will release the steam with a hiss safely in one direction
away from you. After the cooking is over, for Quick

6
release of steam, align the tang of the pressure regulator
to the steam release position marked as “ ” on the lid
handle.
The Pressure regulator acts as both an excess pressure
releasing device and a pressure controlling device.
c. Gasket Release System (GRS)
This is a re-settable safety device. If the
pressure regulator fails to function due
to overload or blockage of the vent
tube, the pressure inside the cooker
goes above the normal level. At this
stage a portion of the gasket is pushed
out through the slot in the lid, releasing the steam
downwards safely. The stove should be immediately
switched off taking care to avoid contact with the line
steam issuing out of the slot. As there is no pressure
inside the pressure cooker, you may now open the
cooker. Follow instruction under section “How to open
your cooker”. If you find any difficulty in opening,
gently push the gasket in with a blunt instrument such
as the handle of a spoon or a fork. Please allow your
cooker to cool and ensure that there is no risk of
scalding while handling the cooker. Remove the
gasket, clean it and if necessary the gasket seating area
on the lid and body of the cooker. Reassemble the
gasket on to the lid. Please check and ensure that the
vent tube is clean and clear. If your cooker is
overloaded beyond recommended capacity, reduce
quantity appropriately before resuming cooking.
d. The Fusible Safety Device
A fusible safety device has been
incorporated as part of the ZPD (Zero
Pressure Device). The non-toxic fusible
alloy of the ZPD, floating freely near the
vent tube, is a backup safety device. In
the most unlikely event of the GRS failing to function
the special non-toxic fusible alloy of the ZPD will melt
and let off the steam safely. This could happen only
when the temperature / pressure rises beyond the

7
normal level due to the cooker having insufficient
water or food particles blocking / clogging the vent
tube.
e. Quick Steam Release
After cooking is over, if you want to quickly release
the steam, align the tang of the pressure regulator to
the position marked by ” ” on the lid handle.
f. Visual Pressure Indicator (VPI)
For your additional safety, your Smart
pressure cooker is equipped with a Visual
Pressure Indicator housed in the lid
handle. When the pressure starts building
up inside the cooker, the VPI is pushed
above and will rise above the surface of the lid handle.
This indicates that your cooker is under pressure.
Similarly, after cooking is over and the cooker is taken
off the heat source, the VPI will drop below the surface
of the lid handle when the pressure inside the cooker
drops to “zero”, giving you a visible indication that
you can safely open the cooker.
e. Auto-Lock
The Auto-Lock mechanism in the “open-close” knob
will keep the lid always in locked condition when the
cooker is fully closed and lid handle aligned with the
body handle.

handle comes above the body
handle and is engaged by the
stopper.
The “open-close” knob will
automatically move to “Close”
position and lock the cooker.
Place the pressure regulator on
the vent tube in the lid, in such a
way that the steam outlet on the
regulator cowl is away from the
lid handle and align the tang to the
required setting on the cup in the
lid handle, depending on the
pressure at which you want to
cook.

GUIDELINES TO USE YOUR SMART PRESSURE COOKER
Your pressure cooker comes fully assembled and it is
ready to use.
1. WATER TO BE USED
Every recipe given in the Recipe Book ( separately
enclosed) includes adequate quantity of liquid for
cooking.When you are trying other recipes, make sure
that there is adequate liquid in the recipe for
cooking.As a guideline, when you are using the
pressure cooker, minimum quantity of 2 1/2cups (18
ozs) water must be used for the first 15 minutes of
pressure cooking. Add one cup (7 ozs) for every 15
minutes of additional cooking time (pressure cooking
times are shown in the recipes ). Please note the
cooking time and put in adequate water before starting
to cook. These quantities are in addition to the liquid
required for cooking.
2. Your pressure cooker should not be filled more
than two thirds its capacity for solids and half for
liquids. When cooking liquid foods, please use the
quantity of water as specified in the recipe. For cooking
milk dishes, start with low heat to bring the milk to
boil and then turn it upto pressure. When cooking
beans, lentils, etc. allow a few minutes before closing
the lid to avoid excess froth. Add a spoonful of oil or
any cooking medium while cooking.
3. PROCEDURE:
a. Put adequate quantity of water in the appliance.
Then add the food to be cooked
b. Ensure the gasket is inside the lid.
c. Follow the instructions given under section “How
to close your cooker”. Place the cooker on high heat.
d. As pressure builds up you will see initially, emission
of steam through the ZPD hole and the slot in front of
the lid handle as it takes a little while for the ZPD to
seal the cooker. During this period the steam may
condense and a few drops of water may also drip. This
will stop once the ZPD seals with the pressure build
