5.1 General notes on installation
The following points should be taken into account besides the general principles governing
installation work:
- Planners / construction companies or operators are responsible for positioning and
installing products.

Testing the operation of the steam trap in the installed state is straightforward with the
“ARImetec
®

(refer to Fig. 1 page 4)
The venting valve is operated in a vertical installation position (system connection vertically

- Remove flange covers if present.
- The interior of valve and pipeline must be free from foreign particles.
- Install at highest point of pipeline system, media supply always from below.
Note installation position with reference to flow, see mark on valve.
- Steam line systems should be designed to prevent water accumulation.
- Lay pipelines so that damaging transverse, bending and torsional forces are
avoided.
- Protect valves from dirt during construction work.
- Connection flanges must mate exactly.
- Valves must not be used to take external forces, e.g. they are not designed for
use as climbing aids, or as connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See data sheet for weights.
- Centre gaskets between the flanges.
- Precautions against freezing should be taken in any facilities susceptible to
frost.
