1. Objectives, eld of application and
conditions for use
The Contracor CCT Air Conditioner is a device that can increase or decrease the
temperature of the supplied air, so improving the working conditions of the user.
CCT Air Conditioner can be used with Contracor blast helmet Comfort and Aspect.
WARNING!
Abrasive blasting helmets in conjunction with CCT Air conditioner should
be connected only to a compressed air system that delivers breathing air
according to the European norm EN 12021.
When using the system in non-EU countries all local norms and laws for
the breathing air supply have to be observed.

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.
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
hazards 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 BAH breathing air supply hose is 40 meters.
• The CCT working pressure is 4.5 – 5.0 bar. A lower working pressure will decrease CCT
work efciency.
• The ambient usage temperature should be within +20 °C and + 60 °C.
• When combined use is made of the compressed air, for both the Contracor CCT Air
CONTRACOR®Version 2.0

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.
WARNING!
Do nou use CCT Air conditioner for the cooling down function when ambi-
ent temperature is below +20°C. as ice could form in the cold air outlet
and reduce airow.
1.2. Usage.
Safe use of the Contracor CCT Air Conditioner is solely guaranteed when used in combination
with Contracor blast helmets Comfort and Aspect.
Always comply with the instructions contained in this user’s manual for the chosen blast
helmet. This ensures the safety of the user, and the optimum operation of the Contracor CCT Air
Conditioner.

2.1. 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 BAH breathing 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.
2.2. During use.
Adjust the air volume according to requirements. The desired temperature of the
breathing air is reached within a short time. The air ow indicator in the blast helmet will
warn the user if insufcient air is supplied. Immediately leave the working area if there is an
interruption in the air supply.
Ensure that the breathing air supply hose cannot be trapped, causing interference
with the air supply or preventing a rapid departure from the work area. The Contracor CCT
Air Conditioner does not reduce the environmental noises. The use of supplementary audio
protection is mandatory. It is quite normal that a certain amount of air escapes from the
unused air outlet.
2.3. After use.
After leaving the working environment, disconnect the breathing air supply hose,
release the belt and remove the blast helmet. Clean and inspect the components according
to the instructions given in paragraphs «Cleaning and disinfecting» and «Maintenance and
CONTRACOR®Air Conditioner СCT Art. 10130840 9
inspection». When connecting and disconnecting, ensure that no pollution is allowed to
enter the open hose connections. Comply with the instructions relevant to the chosen blast
helmet. Clean and inspect the Contracor CCT Air Conditioner, as described in paragraph
«Cleaning and disinfecting» and «Maintenance and inspection». Check the hose system
for leakage. Check the functioning of the system. Refer to paragraph «Maintenance and
inspection».
3. Cleaning and disinfecting.
After each use, clean the outside of the Contracor CCT Air Conditioner, using water
and a mild detergent. Then, wipe thoroughly clean with a cloth soaked in clean water. Do
not use any solvents. Using compressed air to blow clean the coupling and the regulator.
Finally, dry all the metal components with a dry cloth to avoid corrosion. When cleaning,
take care not to inhale hazardous matter that may be released during the cleaning. Comply
with the instructions relevant to the chosen blast helmet.
4. Maintenance and inspection.
4.1. Maintenance.
As a result of intensive use and pollution of the compressed air system, it is possible
that after some time, the sound absorbers get blocked with oil or dirt. These can be
replaced. See chapter Spare Parts. To remove the lters, unscrew them by hands. After
replacing the components, carry out a functional check.
4.2. Functional check.
After each cleaning, disinfecting or exchanging components, check the functioning of the
system. When the air ow is correctly adjusted and the air ow indicator shows that insufcient air is
owing into the blast helmet, it is essential that the defect has to be corrected rst. During this check,
hold the blast helmet in the vertical (normal working) position. Inspect all essential components for
damage or pollution and, if required, replace these by original spare parts.
