Operation
Warning: Install the unit according to the instructions in the "Installation" section before attempting to operate it.
Power
Turn the unit on or off by pressing the "POWER" button.
The unit has a three-minute compressor delay in order to prevent potential circuit overloads at start up.
Automatic Restart Feature
The unit will turn on and resume operation automatically when power is restored after a power outage.
The unit will use the same settings that it used immediately before the power outage occurred. Note:
If the power outage is brief, the unit will run the fan alone for three minutes before resuming normal
operation. The delay allows the compressor to depressurize so the unit will function properly when it
enters Cool mode.
Cool Mode
Pressing the "FUNCTION" button cycles between Cool mode and Dehumidify mode. The "COOLING" LED
illuminates when Cool mode is active.
Press the TEMP+ and TEMP- buttons to set the temperature in Cool mode. The selected temperature
is shown on the numeric display. Once set, the desired temperature will blink five times after which the
display will show the current room temperature.
Press the "FAN SPEED" button to cycle between high, medium and low fan speeds. An LED illuminates
to indicate the selected fan speed. When speed is set on AUTO, the unit will automatically select a
fan speed based on the set and ambient temperatures. If ambient temperature is lower than the set
temperature, the fan will run and the "COOLING" LED will blink to indicate that the compressor is off.
When cooling resumes, the "COOLING" LED will remain illuminated.
Dehumidify Mode
Pressing the "FUNCTION" button cycles between Cool mode and Dehumidify mode.
The "DEHUMIDIFY" LED illuminates when Dehumidify mode is active. In Dehumidify mode, the fan runs
at a fixed speed and temperature controls are irrelevant. For optimal performance in Dehumidify mode,
close windows and doors, remove the top drain plug and route user-supplied drain line to external
drainage.
Timer
The "TIMER" button allows you to schedule the unit to turn on or off automatically.
Timer On (Note: The unit must be off to activate the Timer On function. Confirm that mode,
temperature and fan speed settings are correct before activating the Timer On function.) Activate the
timer by pressing the "TIMER" button. Press the TEMP+ and TEMP- buttons to set the delay (in hours)
before the unit will turn on. The number of hours is shown on the numeric display. The number will flash
on the screen five times before returning to the current temperature.
Timer Off (Note: The unit must be on to activate the Timer Off function.) Activate the timer by pressing
the "TIMER" button. Press the TEMP+ and TEMP- buttons to set the delay (in hours) before the unit will
turn off. The number of hours is shown on the numeric display. The number will flash on the screen five
times before returning to the current temperature.
Quiet Control Mode
The unit includes a Quiet Control mode which regulates the cooling via the timer and microprocessor to
achieve quieter operation levels when noise is an issue.
To activate, press the "QUIET" button. The Quiet LED will turn on. Set the desired temperature and
then set the timer to the duration of the Quiet Control mode cycle. During the course of the cycle,
the microprocessor memory will adjust the preset temperature by 0.9°F (0.5°C) every 30 minutes
until it reaches the desired temperature. Once the temperature is reached, the unit will maintain the
temperature for the duration of the set time.
Changing Degree Units
The unit can display temperature in both Celsius and Fahrenheit. The default setting is Fahrenheit.
To toggle between temperature modes, put the unit in standby mode. The air conditioner is in standby
mode when it is plugged into live AC power, but powered off. Then, hold the "FUNCTION" key for 10
seconds. To verify the degree units have changed, power on the unit.
