Do not install DCR / DCRE insert before Gasket soldering
Pos 5
Note: Confirm correct top cover gasket is selected for DCR or DCRE
Note: Do not reuse the gasket
Customer best practice will still be needed:
•Use wet wrap when installing.
•Braze the joints.
•Let them cool down.
•Clean the brazing /welding area after the installation (remove remaining flux with a brush).
•This is an important operation and needs to be done with great care to remove all remaining flux.
•Paint / Anti-corrosive needs to cover all open steel parts, areas where the black original paint has been burnt due to brazing and at least 3 cm approx of the copper.
•Paint the joints twice.
