To retrofit the outdoor unit by using the existing piping, be sure to:
• Confirm that the existing pipe diameter, length, and height difference between outdoor and indoor unit meet the
requirements list above.
• Confirm that the maximum pressure for the indoor unit is equal or higher than the maximum pressure for the
outdoor unit.
• Confirm that the indoor unit is compatible with R-410A, and utilizes a Thermostatic Expansion Valve (TXV).
If existing indoor unit utilizes an orifice plate, replace the orifice plate with a R-410A TXV.
