3. Preconditions for use:
This Respirator must be used strictly in accordance with this instruction leallet and the instructions supplied
with the corresponding head-units (hoods).
Compulsory Information for the use of a powered respirator with the user must read and understand ail the
following "Instructions for Use" weil to be able to use the respiratory protective system correctly. When the
blower unit is switched off little or no respiratory protection is to be expected. When the blower unit is
switched off a rapid buildup of carbon dioxide and depletion of oxygen within the head unit may occur and so
it is essential not to use the blower unit when it is switched off.
THE UNIT MUST NOT BE USED:
ln an atmosphere that is immediately hazardous to user hygiene or health and or has oxygen content of less
than 17% or contains unknown substances.
In confined spaces or unventilated areas such as tanks, pipes, canals etc.
Near to flames and or sparks ln areas with danger of explosion.
In an area where there are high winds.
If the blower unit stops working due to any reason, the user must leave the contaminated area
immediately.
It is also essential that:
Nothing is allowed to touch the moving parts.
There is no attempt to modify or alter the unit or filter in any way
No water or other Iiquids enter the unit in any way -in particular the motor and fan, the filter or the battery.
Make sure that the headpiece fits the user's face perfectly. Only then the efficiency of the system is sufficient.
The protective factor of the complete system is reduced if the seal of the headpiece is not fitted properly, for
e.g. due to beards or long haïr intervening into the seal line. There is a possibility that the hose to the head
unit may become caught up in use. The blower unit should be positioned on the person in such a way as to
reduce this possibility. Filters cannot be fitted directly to the head units and should not be adapted to do so.
Correct respiratory protection will not be provided if any parts of the equipment are modified At very high
work rates the pressure in the device may become negative at peak inhalation flow Airkos* systems are for
use only by competent, trained personnel.
Filters should not be modified to fit different blower units.
ATTENTION! If any of these conditions are not kept or followed, the warranty is automatically invalid.
The user is advised to leave the contaminated area immediately if:
The Manufacturer's Minimum Design Flow (MMDF) warning Alarm sounds.
Breathing becomes difficult
Dizziness or distress occurs.
Any part of the system becomes damaged.
Airflow into the Head-Unit decreases or stops.
Contaminant can be smelt or tasted inside the Head-Unit
Materials that may come into contact with the users skin are not known to cause allergie
reactions to the majority of individuals but in the unlikely event of a reaction, the user should
immediately leave the contaminated area, remove the unit and seek medical advice.
4. System Overview:
The Airkos* unit is a belt mounted powered respirator with a replaceable, disposable high efficiency
particle filter system. The system is certified with the helmets the PL-2B01/2013 and GT-2B01/2013 helmets
and they cover head sizes from 535 to 600mm circumference.
The Airkos* unit contains a removable 8hr rechargeable battery pack.
The Airkos* unit will warn the user when the MMOF of 170 Umin, is not achieved with its audible alarm.
ln operation once the alarm sounds, the user must immediately leave the work area and reach an area
norninated to be safe. The unit has visual alarm for a low battery and a multiple alarm audible, visual with
vibration for a blocked or missing filter. Oepending on the fault, the user should replace the Pre Filter with a
new one (In very dusty environments the Pre Filter will need changing frequently) and or re-charge or
change the battery for a fully charged one. If the blocked filter alarm continues to sound the main filter should
be changed. Only when the unit will function with the alarm switched off and the flow rate has been tested to
be acceptable, should the user return to the work place.
The filter has been developed especially for this unit. It is used to filter the air the user will breathe. It is
essential that the user checks the filter for any signs of damage or deformation that could potentially let
contaminated air into the unit. The filter must be disposed of if the filter is damaged or if cloqqed to the point
of triggering the systems alarm mechanism.
