Types of device PA1 ÷ PA*2 are designed for extinguishing
hard substances of organic origin (wood, paper, fabric, etc.),
various kinds of explosive and dangerous fluids (petrol, oils,
grease, spirits, etc.), gas and electric devices under high
voltage up to ***0 V with ABC kind of powder on the initial stage
of inflammation (inflammation class definitions A-B-C).
Devices are designed for usage in the regions with a moderate
to cold climate with temperature from –*0C to **0C, disposing
them both inside and outside ensuring protection of devices from
heat and atmospheric precipitation.
Devices must be disposed in the place within the sight and
access beside flammable locations. The devices can be placed on
walls vertically with a help of suspension parts available in the
kit and within a hand’ s reach. Devices can be placed on the
floor, in the cabinets, niches etc. When installed in a vehicle,
the device can be placed horizontally using a special support.
Construction and principles of operation.
Devices consist of a pressure-proof shell filled with a fire
extinguishing powder and a launch mechanism with a rubber hose
attached (PA3 ÷ PA*2) or a special muzzle for powder discharge
(PA1 ÷ PA2).
Shell must be under permanent nitrogen (N2) pressure shown
with a detecting pointer settling itself in the middle of the
green zone on the scale. Device is considered unworkable, if the
detecting pointer settles itself in the red zone on the scale (on
zero section after discharge).
Launch mechanism is launched by pushing upper handle down
until full stop and keeping it in this position after launch.
Please consider that the handle is blocked with a special safety
ring to avoid accidental push when moving the device. Remember to pull the ring (PA 1B; PA2A-yellow cage)
before pushing the handle!
Rubber hose is designed for effective control of powder jet
when extinguishing fire. When launching the device, please hold
it firmly so that the reactive power of powder jet does not pull
it from the hands. The device can be launched permanently and
with intervals by pushing and releasing the upper handle. The
remaining pressure in the shell after disengaging the device is
preserved for not less than 5 minutes. The device must be discharged in a vertical
position!
Safety rules.
As there is a permanent (*5*1) bar pressure in the shell of
the device, please follow safety rules when working with the
device.
Safekeeping of the device in the premises must be in the
competence of the person in charge according to “Fire safety
rules” No.*2.
In case devices are used in complicated climatic conditions,
exposed to vibrations or petrol vapours, the running inspection
time can be short.
The shell of device must not have deformations, dints,
corrosion, damaged paint or indicator, bent handles, please make
sure the hose and the safety ring (PA2A – yellow cage) in the
launch mechanism are not missing. Exploitation of device is not
allowed without a manual in the state language attached to the
shell! The detecting pointer must be in the green zone on the scale
and the safety ring must be sealed!
Device must be delivered to service centre for re-charge and
inspection every time after it has been used.
Guaranty.
“Valpro” Ltd. guarantees compliance of technical
parameters of device to the norms and standard operation for *4
months after date of production (charge) that is printed on the
cylinder of the device under condition that the above mentioned
requirements of the usage of the device are executed.
In case during the guarantee period the pressure in the shell
of device has decreased (the detecting pointer settles itself in
the red zone on the scale), the manufacturer undertakes to
replace the device or perform a repair free of charge upon the
user’s request under condition that the above mentioned
requirements of the usage of device are executed.
