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 eg. Due to beards or long hair 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.
CR-2B01/2013 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 is 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 allergic
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 CR-2B01/2013 unit is a belt mounted powered respirator with a replaceable, disposable
high efficiency particle filter system. The system is certified with the PL-2B01/2013 and GT-
2B01/2013 helmets and the helmet covers head sizes from 535 to 600mm circumference.
The CR-2B01/2013 unit contains a removable 8hr rechargeable battery pack.
The CR-2B01/2013 unit will warn the user when the MMDF of 170 L/min, is not achieved with its
audible alarm.
In operation once the alarm sounds, the user must immediately leave the work area and reach
an area nominated to be safe. The unit has audible and visual alarms for a low battery and a
blocked filter. Depending 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 changes. 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 clogged to the point of triggering the systems alarm mechanism.
The removable rechargeable battery used is a Lithium Iron cell. When supplied the battery may
hold a small charge, the unit should be run flat and then charged for sixteen hours before the
first use.
