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).
