• If a power failure occurs, all pre-set oper-
ating programs will be removed from the
electronic control board’s memory. They
must be reset before the unit will operate
properly.
• During Auto Cool, Cool and Sleep Modes,
once the preset temperature is reached,
only the compressor will cycle OFF. The
fan will remain running.
• Operating the air conditioner when the
outside air temperature is below 70°F will
result in the evaporator icing up.
CHECK FILTER
The CHECK FILTER indicator
light comes on every 720
hours of air conditioner opera-
tion indicating that the standard filter needs to be
cleaned. The 3M Filtrate filter must be replaced.
Press the FILTER RESET key to reset the CHECK
FILTER indicator light. The indicator light will turn
off.
OFF mode
Press the OFF key to turn the
air conditioner off. Once turned
off, the mode, fan speed and
temperature at the time the
air conditioner is turned off
are all stored in the electronic control and are re-
turned to the display the next time the air condi-
tioner is turned on.
MODE SELECTION
Press the MODE key until the
indicator light comes on for the
setting desired. Choose AUTO
COOL, COOL, or FAN.
AUTO COOL - Cools room to
a preset temperature while it
automatically controls the fan speeds. The pre-
set temperature can be changed.
COOL - Cools the room to a preset tempera-
ture. Adjust the fan speed to LOW, HIGH or
TURBO.
FAN ONLY - Fan runs continuously to circulate
the air. No cooling takes place. Adjust the fan
speed to LOW, HIGH or TURBO.
FAN SPEED SELECTION
Press the FAN SPEED key until
the indicator light comes on for the
desired setting. Choose LOW,
HIGH or TURBO. When the fan
is operating at LOW, HIGH or
TURBO, the fan circulates air
continuously.
LOW - Sleeping comfort
HIGH - Normal cooling
TURBO - Maximum cooling
Select the FAN SPEED during the COOL or FAN
modes. If the fan speed is changed during AUTO
COOL mode, the mode will change to COOL
mode.
SLEEP MODE
Press the SLEEP key to select
the SLEEP mode. The SLEEP
indicator light will light up. Press
SLEEP again to turn it off, and
the indicator light will go off.
SLEEP mode operates the cooling mode at LOW
fan speed. This mode allows the room tempera-
ture in the first two hours to increase 3°F above
the preset temperature. It will remain this tem-
perature until SLEEP mode is turned off. During
this mode the display’s light intensity will decrease.
SLEEP mode is available in COOL mode only,
not in AUTO COOL or FAN ONLY.
