FOR OUTDOOR UNITS
WITH AUXILIARY
ELECTRIC HEATER
When outside temperature
is below 32°F (0°C), we
strongly recommend
keeping the unit plugged
in at all times to ensure
smooth and continuous
performance.
NOTE: If the air conditioner runs for an extended period of time in cooling mode and
the humidity is high (above 80%), condensed water may drip out of the unit. If this
should occur, set the vertical air flow louver to its maximum angle (vertical toward
the floor), and set the unit to HIGH fan mode.
Optimal Operation
Doors and
windows should
be kept closed
To achieve optimal performance, please
note the following:
Keep doors & windows closed.
Limit energy usage by using
TIMER ON and TIMER OFF
functions.
Do not block air inlets or
outlets.
Regularly inspect and clean air
filters.
