Condenser Coil
Removal
1. Recover the refrigerant charge.
2. Remove the condenser grille.
3. Unsolder the inlet and outlet refrigeration line connections from 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.
