GENERAL
The high wall fan coil unit provides quiet, maximum comfort. In addition
to cooling and/or heating, the high wall fan coil unit matched with an
outdoor condensing unit filters and dehumidifies the air in the room to
provide maximum comfort.
IMPORTANT: The high wall fan coil unit should be installed by
authorized personnel only; using approved tubing and accessories. If
technical assistance, service or repair is needed, contact the installer. The
high wall fan coil unit can be set up and operated from the remote control
