Installation
Soldering
After charging, mark the system with the refrigerant and the oil used.
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.
