OUTDOOR UNIT INSTALLATION
Install Drain Port and Drain
Hose (for heat-pump model
only)
The condensate drains from the outdoor unit when
the unit operates in heating mode. In order not to
disturb your neighbor and protect the environment,
install a drain port and a drain hose to direct the
condensate water. Just install the drain port and
rubber washer to the chassis of the outdoor unit,
then connect a drain hose to the port as the figure
demonstrates.
