Before using the system it is essential that you read these instructions and ensure that the correct equipment has
been selected. Always be aware of the limitations of use of the equipment and that it is appropriate to the task.

1. WARNINGS

If these instructions are not followed or the unit is used incorrectly the system may not offer protection to EN12941/42 or EN 146.
Power units offer NO protection unless a main filter(s) is fitted.
In a power off situation the headpiece offers no respiratory protection and rapid CO2 build-up and oxygen depletion may also result. This is an
abnormal situation.
Power off is an abnormal situation regardless of whether a full hood, half suit or mask is used.
At high work rates the pressure inside the headpiece may become negative at peak inhalation.
The system should not be used in oxygen deficient or oxygen enriched atmospheres.
The user must ensure that the nature of the hazard is identified and that the system offers an adequate level of protection.
This unit should not be used where the nature of the hazard is unknown.
This unit is NOT intrinsically safe and therefore should not be used in explosive atmospheres
Be aware that the hose protrudes from the back of the headpiece and take care to avoid snagging.
In high wind velocities the assumed protection levels may not be achieved.
The full hood and half suit provide no protection against impact to head, face or eyes.
Respiratory protection will be reduced unless the hood is correctly fitted and properly maintained.
Do not confuse the markings on any filter which relate to standards other than EN12941 or EN12942 with the classification of this device when
used with that filter. The classification for EN12941 will begin with "TH" and for EN12942 will begin with "TM". Filters should only be fitted to the
power unit, do not attempt to fit them directly to a hood or helmet.

3. 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.

4. 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.

Tel. [phone] Fax. [phone]

Allow the charge to continue as the charger will try and trickle charge the battery up to a acceptable pre-set level before commencing the battery
charge, when the RED LED will continuously illuminate (this may take several hours) . If the charger refuses to charge the battery it may be faulty
– contact Centurion Safety Products for further help and assistance.
It is possible that a battery in this state may require several charge attempts to fully charge the battery.

*It is not recommended to deeply discharge a battery by running the power unit until the battery is completely flat since this may permanently
damage the battery.

If the power unit is to be stored without use for more than 3 months the battery must be detached from the power unit before storage.

5. FILTERS

5.1 General (Main Filter)

DUST FILTERS (particulate)

The filter(s) must be changed at regular intervals as determined by a competent person and must be changed when a drop in airflow is indicated
by either the electronic alarms or airflow indicator.

GAS/DUST FILTERS

The filter(s) must be changed at regular intervals as determined by a competent person and must be changed when a drop in airflow is indicated
by either the electronic alarms or air flow indicator or when any breakthrough of contaminate is detected by smell or taste.

GAS CANISTER

The Canisters(s) must be changed at regular intervals as determined by a competent person or when any breakthrough of contaminate is detected
by smell or taste.
We recommend the following MAXIMUM environmental contamination levels for filters as defined by EN 12941/2.
Class 1 Gas/Dust filters (e.g. M09A1/P2) = 500 ppm 200mg/m3
Class 2 Gas canisters (e.g. M23A2) = 1000ppm N/A
Class 2 Gas combination/Dust canisters (e.g. M23 A2B2/P3) = 1000ppm 100mg/m3
Dust filters TH2P (e.g. M23P2/5) = N/A 400mg/m3
Dust filters TH3P/TM3P (e.g. M23P3/5) = N/A 200mg/m3

5.2 MAGNUM 1000, 2000 Power unit (M23/1000, M23/2000)

Pre-filters (General)

The pre-filter is an optional item, which sits in front of the main filter and removes coarse dust before it reaches the main filter.
Pre-filters, in themselves, do not offer any respiratory protection and hence must only be used in conjunction with a main filter.
The pre-filter should be changed immediately a drop in airflow is noticed.
Frequent changing of the pre-filter will maximise the life of the main filter.

Pre-filter Part number: M23PF/10 (For use with M23P2/5 & M23P3/5 filters only)
Pre-filter replacement

Outside surface of the power unit must be de-contaminated before changing the pre-filter
Open the front cover of the Power unit by easing open the right hand side.
Remove pre-filter with the minimum disturbance to the main filter.
Locate pre-filter on top of main filter centrally and without overlapping
Close the cover over the pre-filter/filter, taking care that it does not damage the filter media.
Press down on the centre of the cover until it snaps closed.

If a pre-filter is not used the main filter should be changed immediately the clogged filter alarm sounds/indicates or the air flow indicator, indicates
reduced airflow.
If a pre-filter is used it should be changed immediately the clogged filter alarm indicates or the airflow indicator, indicates reduced airflow.
(This may be more frequently than if a pre-filter is not used).
If after changing the pre-filter the clogged filter alarm sounds/indicates reduced airflow or the airflow indicator indicates reduced airflow.
Within a short period of time, the main filter should be changed as detailed (see Main filter).
