with the top of the outlet ring.
NB
It is possible that the air flow of the power unit when fitted with a fully charged battery pack and a new or servicable filter/pre-filter will be such
that when the airflow indicator is located in the outlet ring (See diagram I) it will be expelled.
This is
not
a fault condition but an indication of airflow above the designed limits of the indicator, it is an indication of sufficient airflow.
If you have both replaced the filter and fully charged the battery and line B is still not visible the unit and battery should be returned to the
supplier.
AIRFLOW INDICATOR FITTING
Line B fully visible
Unit has sufficient airflow
Line B obscured/not visible
Battery flat or blocked filter
To check for a flat battery replace filter and retest
To check for blocked filter, charge battery and retest.
Once the battery has been charged and the filter has been fitted the airflow should be checked before each use and
when a change or suspected change in airflow conditions is detected.
MAGNUM 2000 POWER UNIT
The Power unit is designed to exceed the requirements of EN 12941 in that it will provide a flow rate of at least 140 litres/min for at least 4 hours
under all conditions, assuming a fully charged battery at start. (Minimum design duration = 4 hours).
Duration of up to 8 hours can be typically achieved dependent on various conditions.
The Power unit will give an audible and visual alarm when either the clogging of the filter causes the airflow to drop to the minimum design flowrate
or when the battery voltage drops to a level below which it could not safely power the Power unit. When either of these conditions occur a
frequently repeating audible bleep is emitted and in addition the yellow LED (Light emitting diode) on the top of the Power unit flashes if the filter is
clogged or the red LED flashes if the battery is low.
When either alarm condition occurs during use the wearer should leave the contaminated area immediately and replace the filter or recharge the
battery accordingly.
When first turning the unit on the alarm will beep to indicate the correct functioning of the alarm system. If the beep stops after a few seconds the
airflow is sufficient to proceed with using the unit.
MAGNUM 8500 POWER UNITS
The Magnum 8500 units are activated using a rotary control knob, which should be set to the correct setting as indicated on
the top of the unit. ( see diagram )
Counter clockwise setting for Headpieces/ Hoods/ Half Suits only.
Centre setting for Power Off.
Clock wise setting for the Full facemask only.
When used with TH2 Headpieces, TH3 Hood or Half Suit ( Counter clockwise setting)
The Power unit is designed to exceed the requirements of EN12941 in that it will provide a minimum design flow rate of at least 140 litres/min for
theTH2 Headpieces or 120 litres/min for the TH3 Hood / Half Suit for at least 4 hours under all conditions, assuming a fully charged battery at
start. (Minimum design duration = 4 hours). Typical battery duration depends on a number of factors but is usually around 8 Hrs.
