Insulation
Use a material with good heat-resistant properties as the heat insulation for the
pipes. Be sure to insulate both the gas-side and liquid-side pipes. If the pipes are
not adequately insulated, condensation or water leakages may occur.

10.2.7 Disposal Of Outdoor Unit Drain Water
If a drain elbow is used, the unit should be placed on a stand which is taller than 1-31/32" (50 mm).
If the unit is used in an area where temperature falls below 32°F (0°C) for 2 or 3 days in succession, it is
recommended not to use a drain elbow, for the drain water freezes and the fan will not rotate.
Install the hose at an angle so that
the water smoothly flows out.
