APPLICATIONS AND LIMITATIONS
When used with filters M23P3/5, M23P2/5 or M23P3SL/6 the Magnum respirator will offer protection against dusts, particles, fumes and aerosols
(solid and liquid based) to the levels detailed.
No protection is given against gases or vapours.
The Magnum system should not be used where airborne concentration of contaminant exceeds the Assigned Protection Factor (APF) x the
Occupational exposure limit (OEL)
The system is recommended for use in the temperature range +5
°
to +35
°
C and in conditions where relative humidity does not exceed 90%.
Protection Factors
The efficiency of all types of respirators is classified by the protection factor rating system. There are two main classifications for protection factors,
these are:
Laboratory Protection Factor
(also known as Nominal Protection Factor)
This is the minimum level of protection the equipment has to demonstrate for each of a panel of test subjects under laboratory conditions to gain
approval to the appropriate class of the performance standard.
Assigned Protection Factor (APF)
BS4275 or EN 529 acknowledges that laboratory performance is not always achievable in real use.
These figures are taken from BS4275: 1997 and are the minimum level of protection which it is calculated 95% of wearers who are trained in the use
of the equipment should achieve in practice, with well-maintained equipment. These figures are valid for use in the UK and may differ in other
countries.
For further information regarding protection factors please contact our technical advice service.

PREPARATION FOR USE
Battery
The power unit is fitted with a rechargeable battery pack, which requires charging before use. Ensure you are using the correct charger for your
battery pack (See Section 2).
Standard Charger (M23P2/4BC or M23HD4BC) –
When charging the battery connected to a Turbo unit the turbo unit must be turned off.
Plug the charger into an appropriate mains supply. Connect the battery charger plug to the charger socket on the battery pack. The LED indicator
will light if the charging circuit is satisfactory.
Batteries are supplied in a discharged condition, and must initially be charged for 20 hours before use. Subsequent charges only require 16 hours.
IOvercharging the batteries may permanently damage them.
Intelligent Charger (M23UIC) –
This charger will charge all Magnum battery packs and will operate on both UK and European Voltages.
To change the mains plug from European to UK and vice versa unplug charger from mains and push up switch marked “Open” in the direction of
the arrow the plug should then pop out. Insert the replacement plug into the charger pushing firmly until it “clicks home” Batteries may be charged
on or off the turbo unit.
Batteries must be charged indoors at an ambient of between 10ºC and 30ºC. Do not cover charger.
Important :
In excessive cold or warm environments the recharging device may suppress the charging current to standby level so the battery will
be not be charged. Never charge in a potentially explosive atmosphere.
To use :
Plug the charger into the main power supply (100 – 240V AC – 50-60 HZ). When no battery is connected, the LED (Light emitting Diode)
indicators light on the front of the charger should not be lit.
When charging the battery connected to a Turbo unit the turbo unit must be turned off.
Plug the charging connector into the socket in the rear of the battery pack.
The RED LED indicator will flash for a few seconds indicating that the charger is checking the status of the battery pack. The RED LED should
then light continuously indicating that the battery is being charged.
When the battery is fully charged the RED LED will go out and the GREEN LED will indicate. At this point the battery will be in “trickle charge”
mode, this will maintain the battery’s charge. The battery can be left permanently connected, if desired, until required for use.
Note :
A new battery, a battery stored for a very long period or a battery that has been run completely flat so that is deeply discharged* may not
function correctly.
If when starting to charge such a battery the RED LED continues flashing for more than 10 seconds the charger has detected either a very deeply
discharged battery or a faulty battery.
