5.2 Installation instructions for welding
It should be noted that fittings must only be welded by qualified persons using appropriate
equipment and working in accordance with technical regulations.
The responsibility lies with the system operator.
Please refer to the catalogue sheet for information on type and instructions relating to
welding socket weld ends/butt weld ends.
When welding products to the pipeline system they should be adequately cooled to prevent
any adverse effect on the complete controller assembly (Pos. 24) or possibly the sealing
ring (Pos. 26). The heat-affected zone should be restricted to the immediate weld seam
area!
Note pre- and post-welding heat treatment in accordance with Material Fact Sheet DIN EN
10222.
5.3 Controller adjustment
The steam trap is manufactured with 2 different capsule types. Adjustment is not possible.
5.4 Performance control with ultrasonic instrument
Testing the operation of the steam trap in the installed state is straightforward with the
“ARImetec
®
-S” function tester.
Refer to data sheet „ARImetec
®
-S“.
5.5 Installation position
The steam trap can be installed in any position except with the cover (Pos. 6) down.
Note direction of flow when installing, see marking on valve.
6.0 Putting the valve into operation
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50°C) or low (< 0°C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.
