The trap body must not be subjected to sharp increases in pressure.
The dimensional allowances for corrosion reflect the latest state of technology.

Installation
Float-operated steam traps can – depending on the design of the trap body – be installed in
horizontal or vertical lines with downward flow. Conversion to obtain a different flow direction
is possible:
Flanged design
1. Observe position of installation. The name plate E must always be on top.
2. Observe the direction of flow. The arrow indicating the flow direction A is on the trap body.
Change direction of flow of UNA 14, UNA 16, UNA 16 A or UNA 14 P if necessary.
3. Consider space required for opening trap. When the trap is installed a minimum space of at least
120 mm is required for removing the cover I!
4. Remove plastic plugs. They are only used as transit protection.
5. Clean seating surfaces of both flange faces.
6. Install trap.
