Design with socket-weld ends
1. Take position of installation into account.

3. Consider space required for opening or servicing the equipment. When the Vaposcope is installed
a minimum space of 70 mm is required for replacing the sightglass C .
4. Remove plastic plugs. They are only used as transit protection.
5. Clean socket-weld ends.

Attention
■ Only qualified welders certified e. g. according to EN 287-1 may weld the equipment
