Installation
Brazing
Welding
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.
⚠ Do not install gasket before soldering.
Note: Confirm correct top cover Gasket is selected.
There are 2 gaskets:
– DCR and DCR/H
– DCRE
Recommendation:
Apply a small amount of oil to the gasket before assembly. Preferably synthetic POE or PVE oil, although any general-purpose oil can be used.
