General safety instructions

4

The regulator may only be mounted, started up or operated by trained and
experienced personnel familiar with the product.
According to these mounting and operating instructions, trained personnel refers
to individuals who are able to judge the work they are assigned to and recognize
possible dangers due to their specialized training, their knowledge and
experience as well as their knowledge of the relevant standards.
All safety instructions and warnings in these mounting and operating instructions,
particularly those concerning assembly, start-up and maintenance, must be
observed.

4

For appropriate operation, make sure that the regulator is only used in
applications where the operating pressure and temperatures do not exceed the
operating values based on the sizing data submitted in the order.

4

Note that the manufacturer does not assume any responsibility for damage
caused by external forces or any other external factors.
Any hazards which could be caused in the regulator by the process medium or
operating pressure are to be prevented by means of appropriate measures.

4

The Type 2040 Safety Temperature Monitors do not have their own potential
ignition source according to the ignition risk assessment stipulated in
EN 13463-1: 2001, section 5.2, even in the rare incident of an operating fault.
Therefore, they

do not

fall within the scope of Directive 94/9/EC.

4

The regulator complies with the requirements of the European Pressure Equipment
Directive 97/23/EC. The declaration of conformity issued for a valve bearing the
CE marking includes information on the applied conformity assessment procedure.
The declaration of conformity can be provided on request.

TÜV typetesting/EC type examination

The Type 2040 Safety Temperature Monitors are typetested by TÜV (German technical surveil-
lance association). The test mark is available on request.
An EC type examination according to Pressure Equipment Directive 97/23/EC, Module B has
been performed on the Type 2040 Safety Temperature Monitor.
