straighten any coil fins which were inadvertently bent
during the cleaning process.
Scroll Compressor Replacement
The compressor manifold system was purposely designed
to provide proper oil return to each compressor. The
refrigerant manifold system must not be modified in any
way.
Note: Altering the compressor manifold piping may cause
oil return problems and compressor failure.
Should a compressor replacement become necessary and
a suction line filter is to be installed, install it a minimum of
16 or 25 inches upstream of the oil separator tee. See
Figure 63, p.
110.
Important: Do Not release refrigerant to the atmosphere! If
adding or removing refrigerant is required, the
service technician must comply with all
Federal, State and local laws. Refer to general
service bulletin MSCU-SB-1 (latest edition).
