Safety instructions

The retractable housings InTrac
ated, maintained and, if need be, repaired only by personnel
familiar with the housing and who are qualified for such work.
The customer is responsible for ensuring that:
– only trained and authorized personnel work with the
retractable housings.
– the operating instructions should be supplemented by in-
house instructions regarding supervisory duties and obliga-
tion to report, work organization, personnel qualification, etc.
– the chain has to be always adjusted to the shortest possible
length.
Ensure that the material specification of your retractable hous-

is compatible with the (vessel) cleaning solutions used.
Before every startup, the retractable housing must be checked
for:
– damage to the connections, fastening, etc.

A defective retractable housing must neither be installed nor
put into service. If it is suspected that hazard-free operation is
no longer possible (e.g. housing damaged, connections leak-
ing), the retractable housing and the equipment in which the
retractable housing is installed must be shut down and secured
against inadvertent operation.
