INTRODUCTION
MANTTRA ELECTRIC PRESSURE COOKER is brought to you by MANTTRA INC.
PRINCIPLE OF PRESSURE COOKING:
Under normal circumstances, most foods cook at 212
0F ( 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, 320F (180C) increase in temperature
allows food to be cooked roughly 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 32
0F (180C) roughly. Thus, at these higher
temperatures food cooks much faster.
This is the principle of pressure cooking.

Dear Customer,
Congratulations! On buying our Manttra Chef-Xpress
Electric Pressure cooker.
Basically this is a pressure cooker. Therefore you have
all the advantages of pressure-cooking over normal
cooking, such as saving of time, energy and retention
of flavor and nutritive values. In addition, this unique
product is packed with advanced features, which give
you additional safety and reduce your drudgery.
Following are the features built in:
1. Pot and Lid: The basic pressure cooker’s body and
lid are made of sparkling stainless steel to retain its
lustre forever.
2. Base (skirt): This base at the bottom of the pressure
cooker has a built in electrical heater and a special
connector which links it to your domestic power
supply, through a mating connector in the Electric Unit
(plastic base) through the supplied cord. The connector
with the plastic base has a safety interlock, which
ensures that the grounding pin is first connected before
the power is supplied to the coil. This also provides a
measure of protection from accidental electric shock,
when the cooker body is out of the plastic base. Do not
immerse this in water.
3. Electric Unit (Plastic Base): This
plastic base houses the power
connections and all the electronics for
the programmable controller, the
electrical interlocks and the over
temperature thermal cutout. Do not
immerse this in water. Clean only by wiping with a
damp cloth.
4. Programming:
a. IDLE Mode:When the appliance is connected to the
wall outlet, display shows “00”. The seconds indicator
LED is off, “POWER ON” LED is off and the buzzer is
silent. This is the idle mode.
b. WARM Mode: Full power for 4 minutes
automatically followed by WARM mode, during which
BEGIN A REVOLUTION IN YOUR KITCHEN

10% power only is applied continuously. The LED will
indicate “ ”
c. BROWN Mode: By pressing the “START” button
before the “SET” button, the cooker automatically goes
into the BROWN mode. The LED will indicate “ ”.
The “POWER ON” LED will start blinking.
d. COOK Mode: The controller can be user
programmed to set any cooking time from 4 to 60
minutes. At the end of this time the cooker will beep
and automatically go to WARM mode.
e. The controller has a count down timer. During
operation the 2 digit Light Emitting Diode (LED)
display shows the remaining cooking time, and the
decimal point at extreme right blinks.
5. Safety Features:
a. 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 pressure regulator console
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 pressure regulator
console 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 release of
steam, align the tang of the pressure regulator to steam
release position marked as “ ” on the side of the
console.

QRS
12 PSI

b. Gasket Release System (GRS): In case of abnormal
conditions, when the pressure inside goes beyond the
safe level due to clogging of food in the vent tube, a
portion of the gasket will get pushed through the slot
in the lid, safely releasing the steam through the hole
on the lid located under the pressure regulator console.
This is the second level safety device.
c. Multifunction safety plug:
i. The first function of this device is
zero pressure operation. When the
cooking starts from cold the air inside
the cooker is expelled.
As pressure builds up you will see initially, emission
of steam through the multifunction safety plug and
the slot on the lid console as it takes a little while for
the safety plug 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 safety plug seals with
the pressure build up.
ii. The second function is the fusible plug operation.
In the unlikely event of both the pressure regulator and
the GRS failing to function, the metallic fusible alloy
in the plug melts to release the pressure.
d. Visual Pressure Indicator (VPI):
For your additional safety, your Electric
Pressure Cooker is equipped with a
Visual Pressure Indicator housed in the
safety button console. When the
pressure starts building up inside the
cooker, the VPI is pushed above and will
rise above the surface of the console. This indicates that
your cooker is under pressure. Similarly, after cooking
is over and the issue of steam stops completely, the
VPI drops below the surface of the console, giving you
a visible indication that you can safely open the cooker
by turning the safety button to “OPEN” position by
aligning the arrow mark on the button with the
“OPEN” indication of the cooker on the console.

10
e.Mechanical interlock: The front lid console houses
a 2 way safety button, which works in conjunction with
the multifunction safety plug and the cam that locks
the lid and body together in the closed condition. This
button can be set with the arrow mark on it against 2
positions, namely “Open” position and “Close”
position.
f. Auto Cut Off: In the event of accidental dry heating,
the cooker automatically shuts down the power and
the LED shows “ ” indication. Disconnect the cord
from the wall outlet, open the cooker, clean the pot
thoroughly, add adequate water and restart .

11
This electric pressure cooker comprises of two major
components namely:
a. Electric unit (plastic base) housing the Micro
processor control system
b. Stainless Steel pressure cooker with an attached
base protecting the heater coil
a. Electric unit (plastic Base): This houses the
power connections, all the electronics for the
programmable controller, the electrical interlocks and
the over temperature thermal cutout. The pressure
cooker base (skirt), which protects the coil, has to be
positioned in this plastic base unit properly in the
groove provided in the base. The column contains the
micro controller circuit for time and power control.
This also has 3 buttons one below the other and a LED
status indicator for “POWER ON” function and the 2
digits display which displays in minutes the set time
during programming and the remaining time during
operation.
Once the pressure cooker is loaded with the required
food stuff and recommended quantity of water, close
the cooker and lock it properly as per the instructions
given under section ”How to use your programmable
electric multi cooker” (Page No. 12). While placing
the cooker on the plastic base ensure that it is properly
positioned in such a way that the projection on the skirt
of the cooker body is aligned with the corresponding
slot in the plastic base. This will automatically align
the heater terminals with the mating connector in the
plastic base. In this position, the marking “FRONT”
on the body will be facing the back of the control
column or facing you. The plug of the supplied cord
has to be securely connected to the power socket (wall
outlet).
The right most bottom corner decimal point LED of
the 2 digits display and the “POWER ON” mode LED
on the column will both be off. The 2 digits LED
indicator over the SET button (First from the top) will
