Limitation Of Usage - Contracor CCT 30 305 Gebrauchsanleitung

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 flow indicator.
Before the first 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 fire, 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, sufficient air is allowed to flow 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 flow 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.
