Note:
If any power unit is stored without use for a period of time, the battery must be detached from the power unit.
Important:
In excessively cold or hot environments the recharging device may suppress the charging current to standby level so the battery will be not be
charged.
Batteries which can be charged with this charger:
R23BLI Li-Ion 7.4V ConceptAir Battery pack
FILTERS
Main Filter
Particulate Filters R23P2/5 or R23P2OD/5
The filter(s) must be changed at regular intervals as determined by a competent person and must be changed when a reduced airflow is indicated by
either the electronic alarms or the airflow indicator.
We recommend the following MAXIMUM environmental contamination levels for filters as defined in EN 12941.
Dust Filter TH2P (R23P2/5)
400 mg/m
3
Dust /Nuisance Odour Filter TH2P (R23P2OD/5)
400 mg/m
3
WARNING
Care should be taken when handling filters.
Do not touch the pleated filter medium.
Do not use filters with damaged filter medium.
Do not use filters after their expiry date.
Do not use filters with no or damaged filter seal.
Fitting/changing Main Filters:
Remove the front cover by easing open one side.
Remove the pre-filter (if fitted) and main filter (if fitted) and dispose as solid waste.
Fit the main filter squarely into the power unit.
Place a new pre-filter over the main filter (if used).
Close the cover over the filter, taking care that the cover does not touch the filter media.
Press down on the centre of the cover until it snaps closed.
Pre-filters
Pre-filter
R23PF/10 or R23PFOD/10
A pre-filter is an optional item, which is positioned in front of the main filter and removes coarse dust and/or Nuisance odour 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 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 one 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 when the clogged filter alarm sounds and the LED flashes.
If a pre-filter
is
used it should be changed immediately when 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 and the LED flashes indicating reduced airflow, the main filter should be changed.
ConceptAir Power Unit
The Power unit is designed to exceed the requirements of EN 12941+A2 2008. Duration of up to 8 hours can be typically achieved dependent on
conditions. The power unit has a minmum design duration of 4 hours and will provide a flow rate of at least 140 litres/min for a minmum of 4 hours
under all conditions, assuming a fully charged battery.
The Power unit will give an audible and visual alarm when either the filter is clogged, causing the airflow to drop to the minimum design flowrate or
when the battery voltage drops below a level to safely power the Power unit. When either of these conditions occur a frequently repeating audible bleep
is emitted. The yellow LED 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 power unit on (ensure the unit is fitted with a main filter) 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 use the unit.
ConceptAir Kit Connection
Power Unit
Ensure that the Power unit, Filter(s), Battery and Belt assembly are not damaged. Attach a fully charged battery to the Power Unit by placing the battery
underneath the Power Unit and locating it in the opening. Both sides of the battery must click into place. The battery has a safety feature whereby the
user needs to push both the front and rear battery release buttons to remove the battery.
Ensure that the battery is securely located in the Power
Unit.
Headpiece & Hose Connection
Ensure the headpiece is not damaged and that one end of the hose is securely connected to the headpiece.
NOTE:
It does not matter which end of the hose is attached to the headpiece. Push the other end of the hose into the Power Unit and ensure that it is
locked in position by twisting the hose connection collar.
Please refer to the separate instructions supplied with the headpiece for maintenance instructions.
ConceptAir Kit Wearing
The power unit, battery, belt, hose and headpiece should now be connected as one system.
1 Turn on the Power unit, adjust and place the belt round the waist joining the buckles at the front.
2 Place the headpiece on the head and adjust the headgear to ensure the headpiece is comfortable and sits on the head with the sweatband
positioned above the eyebrows.
3 You should feel filtered air and not hear any alarms from Power Unit
The ConceptAir PAPR system is now ready for use.
