WARNING: Do NOT disconnect
service couplers during the ushing
process. Refrigerant would spray
out of the ttings, and exposure may
cause personal injury.
CAUTION: To prevent vehicle damage,
use a separate oil inject tool to replace
the system oil. Flushing removes
all oil from the system except what
remains in the compressor.
