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.
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.
