Installation of Complete ETV Assembly
1. Clean the tubes for soldering.
2. Place the new complete ETV assembly (and any tubes that were removed) in the same position from which the old one was
removed. The ETV assembly must be installed as shown below relative to the direction of refrigerant flow from the
accumulator to the compressor.
NOTE: The new ETV could interfere with other components if it is not placed in the same position as the old one, or if
retrofitted to SLX/SLXe units built prior to October 2016).
NOTE: Do not disassemble the new ETV to solder it in place.
