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.
Remove the condenser coil mounting bolts and
remove the coil from the unit.
