as described in this user manual, Interspiro service manuals and Interspiro test
instructions.
INTERSPIRO IS NOT RESPONSIBLE FOR
COMBINATIONS OF PRODUCTS, UNLESS PUT TO MARKET BY INTERSPIRO
CHANGES OR ADAPTATIONS MADE TO THE PRODUCT BY A THIRD PARTY


Changes to this document - necessitated by typographical errors, inaccuracies of
current information or improvements and changes of equipment - may be made at any
time without prior notice. Always refer to www.interspiro.com for product updates,
document updates and service bulletins. Exposure to extreme conditions, may require
dierent procedures rather than those described in this manual. The guarantees and
warranties specied in the conditions of sale are not extended by this Safety Notice.
The breathing air with which the cylinders are charged must meet the requirements
according to EN 12021, being free from oil, toxic substances and having low humidity.
The duration of a compressed air breathing apparatus depends on the volume of air
in the compressed air cylinder(s) and the air consumption, which is specic to the
wearer and is aected by the work load. When taking air from the extra air connection,
which some models are equipped with, the air consumption increases and the
duration of the apparatus decreases.
When operating with two separate independently-valved cylinders, both cylinders
must be charged with similar working pressures. Always open both cylinder valves
when pressurizing the breathing apparatus and ensure that both cylinder valves are
kept open during the use of the apparatus.
If tted with a mechanical warning whistle, that warning will be activated at a slightly
dierent pressure than the low air warning triggered by the BAC. For safety reasons,
the rst warning activated should be heeded
If the self contained breathing apparatus is to be used in conjunction with other
personal protective equipment it is important to ensure that the additional personal
protective equipment is compatible with the breathing apparatus and does not impair
the full protection of the respiratory protective device.
Examples of dangers which may require the use of additional personal protective
equipment:
-Liquids, steam or gases which can damage the skin.
-Pollutants absorptive by skin
-Thermal radiation
-Mechanical eects
-Explosive environments.

Fig. 7-A
When the unit is in Run mode with the ADSU/PASS activated (see section 9), the
yellow LED flashes.
During use, the Digital Display can show three dierent values:
. Cylinder pressure in Bar or PSI
. Calculated remaining time in Minutes
.Absorbed temperature in Celsius or Fahrenheit
. Cylinder pressure graph in quarters
Depending on the conguration, the display can show one, two, three or all four of
these values. Furthermore, either of these four values can be shown as the default,
second third and fourth priority value.
Pressing the backlight button (Fig. 7-A) activates the backlight of the display for four
seconds. Pressing the backlight button once more while the backlight is lit toggles to
the next value according to congured priorities.
If only one value is shown, there is no toggle function and the backlight button works
as a backlight only.
Pressing the backlight button repeatedly toggles between values. When the backlight
is switched o aer four seconds the display will always show the default value.
During use, the remaining air time is calculated based on the previous air
consumption. Since the value is calculated, the displayed time can be both shorter
or longer than the actual remaining time, depending on the previous and future work
load and rate of breathing.


The remaining time information must only be used as a complement to the cylinder
pressure information. Low air warnings must always be heeded, regardless of the
remaining time indication.
Until the rst value is calculated from the air consumption, the display shows
“CALC ...”. The rst value is displayed when there has been a signicant pressure
drop, normally aer one to two minutes of breathing.
The remaining time is calculated to the activation of the low air warning.
The unit can be congured to have a heat alarm. When the absorbed temperature has
reached the trigger value, the alarm is activated. An audible beep sounds, the display
alternates to show ‘‘TEMP!!!’’ and the display and main BAC LED flash red.
A battery symbol is always shown on the Digital Display. The symbol shows the battery
capacity of the BAC batteries in four steps. With the Low Battery warning the symbol
starts to flash.
TURN AROUND PRESSURE REFERENCE POINTS TAP REFX OPTIONAL
TAP is a tool for operations when working on one and the same spot. The TAP value
is based on the initial cylinder pressure and the air consumption to reach the spot
where the TAP is calculated.
To calculate TAP, press and hold the backlight button (Fig. 7-A) for 5 seconds until the
display reads TAP REFA xx bar.
To recalculate TAP, press and hold the backlight button (Fig. 7-A) for 5 seconds until
the display reads TAP REFB xx bar, each new calculation gets a new letter.
