onal Safety Lock/Visual Pressure Indicator (VPI)
This device enables users to operate the pressure cooker in complete
safety. The Mul
ti
func
tio
nal Safety Lock has a visual pressure indicator
(VPI) feature that lets the user know when the cooker is under pressure.
The pin inside the Mul
ti
func
ti
onal Safety Lock rises and lowers above the
opening of the cover as internal cooking pressure rises and lowers. As
pressure starts building inside the pressure cooker, internal cooking
pressure pushes up the pin inside the Mul
ti
func
ti
onal Safety Lock cover.
This signals that your pressure cooker is under internal cooking pressure
(15lbs/psi)
(103
kPa).
Once cooking is complete and the pressure cooker is
removed
from the heat source, the pressure inside the cooker will slowly drop
back down and the visual pressure indicator pin will drop back
fl
ush with
the cover. Do not try to release pressure by
tilti
ng the pin with a spoon or
any other kitchen tool. The Mul
ti
func
tio
nal Safety Lock is also a pressure-
building control device. If the pressure cooker is improperly closed, the
Mul
ti
func
tio
nal Safety Lock will not allow internal cooking pressure to
build up.
Secondary Safety Device (SSD)
If the weight assembly knob fails to func
tio
n due to overload or blockage of
the vent tube, the pressure Inside goes above the nominal level (103
kPa)
(15lbs/psi).
The SSD allows the excess pressure to release through the slit provided,
gently under the Handle. The steam release can be seen coming underneath
the Handle and not through the Pressure regulator hole. Once the SSD
operates, the cooker should be removed. The user should also examine the
reason for the pressure regulator not func
tio
ning. Ensure that the vent tube
is clean and clear before resuming the cooking. For the Gasket and SSD to
operate correctly, they must be renewed every 12 months, regardless of use.
The Weight Assembly Knob and Vent Tube
This device ensures that pressure is maintained inside the appliance
while
cooking at 15lb/psi (103
kPa)above atmospheric pressure.
Once
the
pressure
inside the cooker reaches nominal cooking pressure, the weight assembly
releases steam (there will be a slight hissing sound), thus ensuring that
excess pressure does not build up inside the cooker.
