Performing inspection / maintenance
User information for the "products under pressure"
The reservoirs of the CTU are simply pressurized products and are thus
excluded in accordance to Article 1, Paragraph f i); 2014/68/EU of the
Pressure Equipment Directive.
As such, the CTU system does not need to be monitored as per the Industrial
Safety Regulation.
The validity of the owner's obligation to "normal" work equipment provision is
not affected by this in accordance with the Labor Protection Law.
Maintenance work overview
The maintenance and servicing to be performed periodically is described in
