The couplings supplied by KTR should be considered as components, not machines or partly completed ma-
chines according to EC Machinery Directive 2006/42/EC. Consequently KTR does not have to issue a declaration
of incorporation. For details about safe assembly, start-up and safe operation please refer to the present operat-
ing/assembly instructions considering the warnings.
The coupling hubs are supplied in preserved condition and can be stored at a dry and roofed place for 6 - 9
months.
With favourable storage conditions the properties of the elastomer part remain unchanged up to 5 years.
!
The storage rooms must not include any ozone-generating devices like e. g. fluorescent
light sources, mercury-vapour lamps or electrical high-voltage appliances.
Humid storage rooms are not suitable.
Please make sure that condensation is not generated. The best relative air humidity is less
than 65 %.
!
In order to avoid any injuries and any kind of damage please always make use of proper
transport and lifting equipment.
The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise
contractually agreed, packaging will follow the in-house packaging specifications of KTR.
The coupling is generally supplied in individual parts. Before assembly the coupling has to be inspected for com-
pleteness.
