Before Use - Spasciani RN Instrucciones De Uso

2.7.2. Additional warning device
The additional warning device can be installed, upon request, on the RN series devices and allows you to have a
continuous alarm signal, in addition to the intermittent alarm signal already provided with the demand valve.
It is installed on the reducer and simultaneously activates itself with the main warning device
2.7.3. Escape hood for second operator
The escape hood for second operator is an accessory that can be used in conjunction with any SPASCIANI SCBAs.
To use the escape hood, remove the "2nd operator cap" on the pressure reducer and replace it with the "medium
pressure hose provided in the set. Detailed instructions for assembly and use of the escape hood for 2nd operator are
attached to the accessory itself (code instructions 960250000).
2.7.4. Excess flow valve
The valve of the cylinder can be equipped, upon request, with an excess flow valve.
2.7.5. Connections of the medium pressure hose (RN T1 excluded, on request for RN FR T2)
The medium pressure hose, which connects the reducer to the demand valve, is equipped with quick Euro-Coupling
connections (default) or with Spasciani connections (upon request).
2.7.6. Second outlet hose
The second outlet hose is an accessory mountable on request on all SCBA RN series and allows to connect a second
demand valve. NB: when you use the second outlet hose to connect in a second operator, accurately calculate the
autonomy of the device, which will be halved.
2.7.7. ATEX self-contained breathing apparatus
Upon request, the self-contained breathing apparatuses can be provided in the "Atex" version. See section 8 for details
on this line of devices.
3. USE
Warnings
All the preparatory and use operations of the self-contained breathing apparatus must only be carried out by qualified
and trained personnel. Make sure any accessory or auxiliary device or any other type of protective wear used in
addition to the system does not compromise or hinder its safety or hold.
The autonomy of the self-contained breathing apparatus depends on the initial amount of air available and on the
operator's breathing rate, but also on the presence of accessories that could consume the air (i.e. additional warning
device, second output hose). Always use devices that were preventively checked. The operations described here below
must always be followed before use.

3.1. Before use

3.1.1. Cylinder installation
a) Keep cylinder vertically on a flat surface with the valve upwards and connect the reducer to the cylinder using the
appropriate swivel connector;
b) Lie down the equipment and lock the cylinder pulling the belt and closing the buckle.
3.1.2. Connecting the demand valve
Insert the male and female quick connectors of the medium pressure hose. Apply little pressure to connect them.
Please note: Apply little axial pressure on the connections to disconnect them, while simultaneously pulling back the
female connector. Never disconnect if the hoses are under pressure!
Press the button (pos. 1 fig.5) to avoid air leaks when wearing the device.
For breathing apparatus RN T1 and RN FR T2 this operation is not needed since the demand valve is not equipped with
fittings but of a medium pressure hose in one piece already connected to the reducer. If you chose model RN FR T2
provided with a quick connectors medium pressure hose, please see the paragraph above for
connection/disconnection operations.
3.1.3. Check the position of the hoses
The gauge and demand valve hoses are connected to the left shoulder strap via a Velcro closure system.
It is allowed to let the medium pressure hose pass beneath the left arm and fasten it to the waist belt, if so desired.
3.1.4. Check cylinder pressure
Insert the locking device (pos. 1 Fig.5). Open the valve of the cylinder: the pressure gauge should read not less than 280 bar
for cylinders with an operating pressure of 300 bar and 190 bar for cylinders with an operating pressure of 200 bar.
3.1.5. Check the high pressure section tightness
