1. Copper Stub Tube
2. Uniseal Tape (Protects Brazed Connection between Copper Stub Tube and Aluminum Micro-Channel Condenser Coil)
3. Aluminum Micro-Channel Condenser Coil
Installation
1. Clean the fittings for soldering.
2. Place the coil in the unit and install the mounting bolts.
3. Solder the inlet and outlet refrigeration line connections to the copper stub tubes on the micro-channel condenser
coil. Use a heat sink on the copper stub tubes.
IImmppoorrttaanntt:: This unit uses a micro-channel condenser coil. Micro-channel coils are made of aluminum but have
copper stub tubes at the inlet and outlet connections. Use a heat sink on the copper stub tubes to
prevent damage to the uniseal tape and brazed connections (and the aluminum) that attach the copper
stub tubes to the aluminum micro-channel coil. The uniseal tape is used to prevent corrosion between
the copper and aluminum.
4. Pressurize the refrigeration system and test for leaks. If no leaks are found, evacuate the system.
5. Reinstall the condenser grille..
6. Recharge the unit with proper refrigerant and check the compressor oil.
