1. Introduction:

The CR-2B01/2013 is a respiratory protective system which is based on the principle of
circulated over pressured air in the hood. The belt-mounted blower unit delivers air through a
filter and via an air hose into a headpiece (a hood or mask). The supply of filtered air creates
positive pressure inside of the headpiece, which prevents the external contaminated air from
entering the user's breathing zone.

2. Approvals:

The CR-2B01/2013 PAPR has been designed and manufactured to comply with EN12941:
1998 as a TH2P R SL device.

BS4275 (Guide to implementing an effective respiratory protective device program), which the

user is advised to read, defines an EN12941 TH2P R SL device as offering an Assigned
Protection Factor of 20.

The CR-2B01/2013 can only provide this level of protection when used with filters provided by
the manufacturer marked “ CR-2B01/2013 ” and “EN12941:1998 TH2P R SL”.
The CR-2B01/2013 is certified with the GT-2B01/2013 helmets which is certified to EN 175 B.
The CR-2B01/2013 is manufactured under ISO 9001:2000 Quality System.

3. Preconditions for use:

This Respirator must be used strictly in accordance with this instruction leaflet and the
instructions supplied with the corresponding head-units (hoods).

The user must read and understand all the following "Instructions for Use" well 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 build up 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:

In 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

•

In 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.
If no filter is installed.

•

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

•

Water or other liquids 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 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 GT­2B01/2013 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.

5. Unpacking / Assembly / Usage:

5.1. Unpacking:

Check that the package is complete and that no part is damaged due to the transport or for
other reasons.
A package with the complete system including accessories contains:

1. Blower unit incl. Battery and P R SL Filter and Pre Filter and Filter Cover

2. Belt

3. Air hose

4. Air flow indicator

5. Battery charger

6. User Instructions

5.2. Assembly:

Attach the respiratory unit onto the belt: Pass the inner strap through the back of the blower
loops. The pass through the 3 belt loops and then through the buckle.

Fit the battery to the Blower unit:

5.2.1. Waist-Belt Adjustment:

Put the belt around your waist with the blower unit to the back and fasten the two ends together.
If the belt is too loose, slide the male adjuster down the belt, towards the female half. If the belt
is too tight. slide the male adjuster away from the female half.

Repeat the above processes until a comfortable and secure fit is achieved. Once the belt fits
correctly, secure any excess belt material using the Velcro sections.

5.2.2. Particulate Filter:

Use only CR-2B01/2013 filters and Pre Filters as supplied by SISAB.
It should first be ascertained by consulting an occupational hygienist or by calling the
manufacturers technical help line as to whether or not the CR-2B01/2013 Filter will offer
suitable protection from the hazard.
The respiratory power unit is equipped with a high efficiency particle filter of class P R SL and a

Pre Filter.
As soon as the warning alarm sounds, the pre filter should be exchanged or checked. In very
dusty area's this can be necessary on a frequent basis.
The filters must be regularly checked (see Air Flow Test ) and replaced.

Make sure that the new filters are within their expiry date, unused and not evidently damaged.
From the hygienic point of view the maximum working time of a main filter is 180 hours and
should not be exceeded.
It is prohibited to clean the filters by any procedure!

5.2.3. Removing the Filter:

Opening the filter cover: Grip the cover on the right hand side and pull the cover open.

ATTENTION! It is strictly forbidden to use any tools to open the filter cover.

To remove the filter, pull it off the filter seal while rotating it. Clean the unit from dust.

5.2.4. Fitting a new Filter:

Inserting a new filter: Put the filter back into position using the same rotating motion and gently
push until it fits well on the body of the unit.

Re fitting the Cover; follow the alignment as per the pictures. Ensure the filter clips enter the
Blower body, then rotate Clockwise until closed. Do not attempt to use the blower unit without
the cover fitted correctly.

5.2.5. Changing the Pre Filter

The pre filter is a sleeve which is fitted over the main filter. To remove / replace simply pull off
the old filter and stretch the new one into position. It's important to ensure that the filter media of
the main filter is completely covered by the pre filter

5.2.6. Attaching the Hose to the Blower Unit:

Align the pins of the Hose Bayonet connector with the slots in the air outlet of the blower. Push
the Bayonet connector into the blower until it reaches the bottom of the hole and then twist in a
clockwise direction until the locating pins clips into place.

Fitting the hose to the hoods is the same procedure.

5.2.7. Donning the Welding Helmet:

First set the Welding helmets rake and adjust the welding filter to suit (See the helmet’s user
instructions)
Lift the helmet to it’s upper position.
Place over the head and adjust the headgear ratchet wheel by pushing it in and twisting until a
satisfactory tightness is achieved.
Pull the elasticated chin guard downwards and at the same time pull the helmet down. Ensure
the elasticated chin guard fits comfortably under the chin.

The Welding helmet is now ready for use

5.3. Usage:

Switch on the unit by pressing the ON/OFF button on the control panel. The airflow can be
either the low speed 180 l/min or the high speed 220 l/min. The speed denoted buy the lit LED
and the fan symbol. You can change the speed by pressing the ON/OFF switch. Only by
depressing the ON/OFF switch for several seconds will stop the unit.

The unit ensures a constant supply of air. The microprocessor inside the unit automatically
regulates the motor speed to compensate the filter clogging and the battery state. If the
microprocessor cannot keep the adjusted airflow, the unit will sound a 'beeping' alarm (an
acoustic signal can be heard). At which point the user must check the blower unit. If possible,

the microprocessor automatically reduces the airflow to the lower level, if it fails to meet the
lower level, the alarm will still sound. When the airflow falls below the minimum safe operating
level, a second audible alarm joins the first. At this point, the user must stop working at once,
leave the working environment and reach an area nominated to be safe and change the filter or
recharge/change the battery.

To check the battery: When first starting the unit, the battery LED must show red – this shows a
fully charged battery. It is recommended that only a fully charged battery should be used when
starting a work shift.

With a fully charged battery in place, the unit should function normally, but if the audible alarm
still sounds, the user must change the filter. If the problem still persists, see chapter 8 for
additional suggestions.

6. Before use:

6.1 Inspection before use:

Each time before starting work check that:

· all components are in good condition with no visible damage (like holes, tears etc) Replace
any damaged or worn parts. Carefully examine the air hose, seals and the face piece.

· there is a good connection between the air hose and the headpiece as well as the blower unit.

· there is sufficient air flow..(see 6.2.)

· the air is supplied through the whole respiratory system from the blower to the hood.
Charge the battery before the first use. (see 6.3.)

6.2. Air Flow Test:

1. Disconnect the air hose from the Blower unit.

2. Insert the Airflow indicator into the air hose connector and keep the hose in vertical
position at about the eye level.

3. Switch the power unit on. The airflow is sufficient only if the ball indicator reaches the
minimum flow rate level. If the indicator sinks is below the minimum flow rate level, it is
necessary to charge the battery or change the filter. If the problem still persists, see chapter 8

for additional suggestions.

6.3. Batteries:

NOTE ! Batteries are delivered only partially charged, All batteries must be charged before they
are used for the first time. The battery can be charged separately or on the blower unit.
The charger must not be used for any other purpose than that for which it was manufactured.
Do not charge the battery in a potentially explosive atmosphere. The battery charger is intended
for indoor use. It must be protected against damp. The charger controls the charging
automatically. After the battery has been charged, the charger switches to the trickle charging
regime and keeps the battery fully charged. The charging time is 6 to 8 hours.

6.3.1. Battery charging:

1. Check that the voltage of the electrical power supply is correct.

2. Plug the charger into the socket.

3. Connect the battery to the charger. The socket of the battery is positioned on the back side.
The charging state is indicated by a red LED diode light.

4. After charging has been completed, the trickle charging regime is activated: - red LED
diode goes out, the green LED diode comes on at the moment of trickle charging.

5. Disconnect the charger from the power supply.

Do not leave the charger in the power supply if not in use!

6.3.2. Battery changing:

Removing the battery:
Locate the battery catch. Pull back the battery catch and at the same time the Battery can be
removed by lifting upwards.

Fitting the battery: Make sure the battery is the correct way up (as per 5.2) and then slide into
the bower until the battery catch engages. It is essential that the battery catch is fully locked.

7. Maintenance / Cleaning:

The Blower unit, filter housing and head units must all be regularly cleaned to keep them in
good working order.
For single users, the units can all be cleaned with a cloth moistened with luke warm water and
soap.
For multiple users, the units should be disinfected when passed from one user to another.
SISAB recommends that ‘Incidur’ from Ecolad GmbH & Co. OHG is used for disinfecting.
Liquids must not be allowed to enter the workings of the blower unit or get on to the element of
the filter.
Parts should be allowed to air dry. Under no circumstances should any solvents or abrasive
cleaning agents be used. The unit must not be dried using hot air or radiant heat.
The unit should continue to provide protection to the designed specification for 2 to 3 years,
when maintained in accordance with these instructions. Prior to each use the user should check
that the unit is free from defects, such as cracks, split filters and hoses, cracked visors and
helmet components as appropriate

8. Fault finding:

If there is a sudden change in air supply while using the CR-2B01/2013 system, it is necessary
to check the following:

· That all parts of the air-supply system are assembled properly.

· The battery and its connector.

· Whether the charger is not faulty or malfunctioning (if so, diodes do not work).

· Filters and their clogging.

· That there is not a hole in the air hose.

· Whether the hood seal is not damaged.

· Whether the working time after a full recharging of the battery has not decreased (if so, it is

necessary to replace the battery).
