following values:
2216 psi Unit - 510psig to 600psig
4500 psi Unit - 1035psig to 1215psig
Should whistle not sound at the required
pressure, refer to Service Manual.
Important Note: The activation setting of the
LED’s of the Flashing Gauge (if tted) is also
within the above setting parameters. Audible
and visual signals/warnings may however
not activate at exactly the same time. The
LED’s of the Flashing Gauge will switch o
before the audible warning at the following
approximate values,
2216 psi Unit – below 200psig
4500 psi Unit - below 400psig
Following satisfactory whistle test, press reset
mechanism to switch ‘O’ positive pressure.
Connecting Demand Valve to
Facepiece
Check that the facepiece port and the demand
valve O ring are clean and undamaged.
Push the demand valve into the facepiece
port until it clicks into position. A slight turning
motion of the LDV during pushing will aid
connection.

the demand valve away from facepiece - there
should be no axial movement.
Operation
Putting on equipment
Extend the waistbelt and shoulder adjusting
straps.
Put on equipment taking weight on
shoulders by pulling on shoulder adjusting
straps. Do Not tighten.
Fasten waistbelt buckle. Pull ends of waistbelt
adjusting straps (see Fig. 4) until waistbelt pad
is secure and comfortable on hip. Tuck strap
ends between body and waistbelt pad.
Pull down shoulder adjusting straps (Fig. 5)
until equipment is secure and comfortable.
Do Not overtighten. Tuck strap ends under
waistbelt.
Extend facepiece head harness straps, leaving
centre strap in position, (Fig. 7). Put neck
strap over neck, insert neck strap stud into
hole in centre strap of head harness.
Carry out High Pressure Leak Test.
Note: Cylinder pressure must not be less
than 80% full. If pressure is below maximum
charging pressure of the cylinder, this will
reduce available duration to the wearer.
Press the reset mechanism of the demand
valve to switch ‘O’ the positive pressure.
Open the cylinder valve slowly, but fully, to
pressurise the system. Check the gauge.
Putting on Facepiece
Safety Warning: Beards, side whiskers,

interfere with face seal of facepiece, and
adversely aect protection of the wearer.
Detach the neck strap stud from the centre
strap of the head harness.
Spread the harness, (Fig. 7) then place chin
into the facepiece, position harness over the
head locating the harness centre plate with
the back of the head.
Tighten both the lower, then the upper straps
evenly towards back of the head. Fig. 8. Tuck
in strap ends.
On achieving a face seal the positive pressure
demand valves will automatically activate on
rst breath inhalation.
Breathe normally then prior to use perform
function checks.
Function Checks
Inhale and hold breath. Unit must balance,
i.e. no audible leak.
Continue breathing. Expired air should easily
ow out of the exhalation valve.
Press the ‘red’ by-pass button of the demand
valve checking that an additional airow is
delivered into the facepiece.
Close the cylinder valve. Breathe normally to
vent the system. When the gauge indicates
zero, hold breath. Facepiece should hold
onto the face indicating a positive seal.
Note: If a leak detected, open the cylinder
valve, readjust the head harness and retest.
Open the cylinder valve slowly, but fully to
pressurise the system, recheck the pressure
gauge and proceed.
Use
Take gauge reading regularly. Whistle will
sound at whistle warning unit pressure
setting.
Proceed to safe area, at least when whistle
sounds, by shortest and safest route.
Important Note: The activation setting of the
LED’s of the Flashing Gauge (if tted) is also
within the whistle setting parameters. Audible
and visual signals/warnings may however not
activate at exactly the same time. The LED’s of
the Flashing Gauge will switch o before the
audible warning.
Safety Notes:
a. Additional Air Required
If momentary additional airow is required, press
‘red’ bypass button of lung demand valve. In the
unlikely condition of low or blocked airow, or
if required to maintain additional airow, press
and rotate the ‘red’ bypass button to ‘lock’ the
ow setting (80 - 130Litres/min). Duration of
the air supply is reduced while the bypass is
in operation. When set in this condition the
wearer must evacuate to a safe area. If it is
suspected that the apparatus is blocked then an
investigation by a trained authorised person must
be carried out before re-using the apparatus.
b. Excessive or Loss of Airow
In the unlikely condition of high or loss of
airow, close the cylinder valve then immediately
begin to slowly re-open the valve, using it as
an adjusting valve to set sucient airow to
cover the maximum inhalation requirement.
This action must only be carried out in an
emergency situation to escape to a safe area. An
investigation by a trained authorised person must
be carried out before re-using the apparatus.
Note: On SCBA having cylinders tted with
a locking (ratchet) valve, adjustment of the
cylinder valve while wearing the SCBA must
be performed as follows. Reach behind with
the left hand to support the backplate and
at the same time with the right hand, push
and hold in the valve handwheel, rotating the
handwheel clockwise to close the valve then
immediately begin to slowly re-open the valve,
using it as an adjustment valve to set sucient
airflow to cover the maximum inhalation
requirement. Release the valve handwheel
when the required airow is achieved.
Connecting to Independent Air Supply
Note: Ensure independent air supply source
meets pressure and air quality requirements
as dened in Technical Data section of this
User’s Instruction.
Turn ‘On’ the independent air supply then
connect air supply hose to the coupling of
the Buddy Breather connection.
Close equipment cylinder valve and breathe
normally from the independent air supply.
IN AN EMERGENCY - If independent air
supply ‘Fails’, proceed as follows:
