Installation
– continued –
VKE 16-1 Design with socket-weld ends
1. Observe correct position of installation.
2. Observe direction of flow. The flow arrow is on the trap body.
3. Consider space required for servicing. When the test chamber is installed a minimum space is
required for removing the measuring electrode (see table for
Fig. 7
and
Fig. 8
).
4. Remove plastic plugs. They are only used as transit protection.
5. Clean socket-weld ends.
6. Apply arc welding processes 111 and 141 in accordance with ISO 4063.

VKE 16-1 Design with butt-weld ends
1. Observe correct position of installation.
2. Observe direction of flow. The flow arrow is on the trap body.
3. Consider space required for servicing. When the test chamber is installed a minimum space is
required for removing the measuring electrode (see table for
Fig. 7
and
Fig. 8
).
4. Remove plastic plugs. They are only used as transit protection.
5. Clean butt-weld ends.
