Aluminum Coil Removal

For all aluminum coils, the coil has two or four (depending on size of
unit) fin isolators on the top of the coil as shown in
be reinstalled onto replacement coil.
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in premature corrosion failure
of aluminum coil
During coil replacement, when brazing the new coil into the unit, a
guard is needed so copper-to-copper joint braze splatter does not reach
any aluminum parts. This can cause pitting and premature failure due
to corrosion.
Fabricate a metal braze shield of approximately 8" X 8" to protect
aluminum components when brazing (see
The orientation of the fin isolator is shown in
mechanical fitting on the liquid distributor. This connection is not field
serviceable and should not be disturbed.
The copper stub tube connection to the liquid service valve needs to be
un-brazed for coil removal. (See
