1. Objectives, eld of application and conditions for use
The air ow regulator in the selected blast helmet needs to be replaced by the Contracor
CCT Air Conditioner.
The CCT Air Conditioner is used in a working environment where protection of the
respiratory organs, face and head is required against ricocheting medium, particles, mists,
vapors and gasses.
When the CCT Air Conditioner is connected to the compressed air system via the breathing
air supply hose and the BAF airline lter, the breathing air according to EN 12021
simultaneously passes via the red and blue outlets out of the device.
One outlet can be used to channel the treated breathing air via the helmet hose into the
blast helmet.
The required air ow can be adjusted by the regulator. The air ow indicator, which is
integrated in the blast helmet, displays whether sufcient air is passing into the blast
helmet
The Contracor CCT Air Conditioner is a device that can increase or decrease the tempera-
ture of the supplied air by approx. 20 °C, so improving the working conditions of the user.
CCT Air Conditioner can be used with Contracor blast helmet Comfort and North Safety
blast helmets Commander and Panorama.

1.1 Limitation of usage
The Contracor CCT Air Conditioner should at all times be used in combination with a blast
helmet with integrated air ow indicator.
Before the rst use of the equipment, the rapid removal of the gear needs to be practiced.
The system may be used solely by trained personnel, who are also fully aware of the haz-
ards applicable to the work being carried out.
The system is not suitable for working in areas with intense heat radiation, open re, risk of
explosion, or when extremely high concentrations of hazardous matter causing immediate
health risk are present.
It is not allowed to use oxygen or oxygen enriched air.
The maximum permissible length of the high pressure supply hose is 40 meters, the maxi-
mum permissible pressure is 7 bar.
The minimum permissible working pressure is 4.5 bar.
The ambient usage temperature should be within - 10 °C and + 60 °C.
When combined use is made of the compressed air, for both the Contracor CCT Air
Conditioner and the pneumatic tools (e.g. blast pot) it is necessary to ensure that, at the
maximum air consumption of the pneumatic tools, sufcient air is allowed to ow into the
air hood. If necessary, the working pressure can be adjusted.
When the ambient temperature is below freezing point, the humidity in the compressed
air circuit can result in icing-up of coupling or regulator, blocking the further supply of air.
In such cases it is necessary to determine prior to use that the humidity content in the
compressed air (at atmospheric pressure) is less then 50 mg/m3, and is in accordance
with EN 12021.
Generally available compressed air circuits do not usually comply with this requirement.
Exceptionally warm or cold compressed air, a long supply hose and an extreme ambient
temperature could affect the performance of the Contracor CCT Air Conditioner.
If the free outlet is blocked, the ow of breathing air will increase, reducing the degree of
cooling or heating of the supplied air.
Couplings and hose connections must be kept clean during connecting and disconnecting.
All user limitations regarding the chosen blast helmet remain applicable.

3. Prior to use
Ensure that the compressor is switched on and that it has been set to the correct operat-
ing pressure. Check that the compressor is regularly inspected and maintained.
A worn and/or dirty compressor supplies polluted air that will not be cleaned by the lter
system! Make sure that the compressor cannot suck in any dangerous matter via the air
inlet.
Adjust the operating pressure on the BAF airline lter to a minimum of 4.5 bar. Connect
the Contracor CCT Air Conditioner via the brathing air supply hose to the BAF airline lter
system.
Make sure that the Contracor CCT Air Conditioner is correctly secured to the belt, that the
helmet connection of the hose for the breathing air is not leaking, and that the hose is
sufciently secured against inadvertent release. Refer to paragraph “Maintenance and
inspection”. Continue with a test run of at least 3 minutes when using the equipment for
the rst time.
