When installed in predominately cold climates:
• Install a fi eld-provided snow hood to keep out snow and rain.
• Ensure the outdoor unit is installed to avoid direct contact with snow. If the unit is installed in a snowy area, attach a fi eld-
provided snow hood over the coil inlet and/or outlet. If snow accumulated and freezes on the fan inlet and/or outlet, the
system may malfunction.
• Install the outdoor unit at least 19-3/4 inches higher than the average annual snowfall.
• The height of the mounting base must be more than 2 times the average annual snowfall.
• The width of the mounting base must not exceed the width of the unit. Snow may accumulate if the width of the frame is
wider than that of the unit.
• Make sure the fan inlet and the fan discharge of the outdoor unit are facing away from the seasonal wind.
