1 Introduction

1.2 Application

Surface-mounting thermostats Series ATH.-SE-.. are approved for monitoring
installations on steel-hulled ocean-going ships (e.g. steam and boiler plant,
indirect heating systems) as:

❏ Temperature monitor (TW)

❏ Safety temperature monitor STW (STB)

❏ Safety temperature limiter (STB).

The versions comply with DIN EN 14597 and are approved as per the guide­lines of the Classification Societies:

- Germanischer Lloyd

- Det Norske Veritas

- Bureau Veritas

- Pressure Equipment Directive 97/23/EC CE0036
(ATH.-SE-20 and ATH.-SE-70 only)

Cutting through or kinking the capillary of the surface-mounting thermostats

A

Type ATH.-SE-.. will lead to permanent failure of the instrument!

1.3 Marking

H

Surface-mounting thermostats Type ATH.-SE-.. are approved as per DIN EN 60730­2-9.

1.4 Safety notes

In the event of a measuring system breakage, the filling liquid can escape.

H

There is currently no statement by the health authority concerning hazards to
health in the event of short-term exposure and low concentration, e.g. in the
event of a measuring system break.
