6
Braze the field piping.
7
After brazing, put the lower pipe insulation back in place and
close it with the upper insulation cover (after pealing off the
liner).
8
Secure the pipe fixing clamp (C) in place again (2x M5).
9
Make sure that field pipes are fully insulated.
Field pipe insulation must reach up to the insulation you have
put back in place as per procedure step 7. Make sure that there
is no gap between both ends in order to avoid condensation
dripping (finish the connection with tape eventually).
