Thank You
Thank you for purchasing an EdgeStar portable air conditioner. It should provide you with years of
reliable cooling. Among other features, this versatile unit exhausts all the condensate that it extracts
from your air. Additionally, this portable air conditioner features auto restart. If power to the unit is
interrupted, the unit “remembers” its previous settings when power is restored.
In order to properly use all features of this portable air conditioner, please read this owner’s manual
prior to use and store the owner’s manual for future reference. It is also a good idea to save the box
and packaging for this portable air conditioner for off-season storage.
Energy Saving Tips
1. Use the portable air conditioner for the recommended room size. Rooms that are too small can
cause the unit to short cycle and work inefficiently. Rooms that are too large will never cool
completely.
2. Be careful not to obstruct the air flow coming out of the portable air conditioner. A powerful,
unobstructed airflow is crucial for optimum cooling.
3. Keep blinds and curtains closed during the sunniest part of the day.
4. Clean the pre-filter often.
5. Close your fireplace damper, floor grills, and wall grills to prevent cool air from escaping.
6. Avoid opening doors frequently.
7. Note that each additional person in room adds between 100-150 BTU of heat, so the more
people in a room, the more cooling capacity is required.
8. Set the portable air conditioner to maximum cooling and high speed airflow when you first
start it up, and then adjust the unit to a comfortable setting.
9. To provide cooling to a room, this portable air conditioner must always be used with its exhaust
hose attached.
Notes
The portable air conditioner must be plugged into an appropriate power outlet. Refer to the rating
label on the back of the unit for more information.
The portable air conditioner is a compressor-driven cooling system. The air conditioner has an
anti-overheating safety feature that delays the compressor from starting for three minutes after the
air conditioner turns on or when a mode change is made. If the compressor does not immediately
start, it is likely because of this feature.
To protect the compressor from overheating or freezing, it will only operate when the ambient
temperature is between 64°and 100°F.
In the Cooling or Dehumidifying modes the exhaust hose must be used.
When switching into the Cooling mode, cooling may be temporarily delayed as the unit cools
down.

Installation
When you use this portable air conditioner as an air conditioner or a dehumidifier, the
hot air should be exhausted out of the room. When the unit is operating in fan-only
mode, no exhaust is required. You do not need to hookup the window kit and hot air
exhaust hose when you use the unit as a fan.
If you use this portable air conditioner in cooling mode without venting the exhaust
outside the room you are cooling, the net temperature in the room will rise, but the unit
will still cool the area directly in from of its louvers.
This portable air conditioner ships with the accessories for two primary types of
installation: window installation (standard double-hung windows) and wall
installation.

2) Remote Control
TEMP/ TI ME
FAN SPEED
TI MER MODE
ON/ OFF
The six buttons on the remote control are same as the six buttons on the control panel
of the main unit. See the control panel section above for an explanation of how to use
the buttons.
The remote control uses a lithium battery model CR2025. The battery must be installed
prior to using the remote control.
3) Modes
Dehumidifying
1) Plug the power cord into a power outlet.
2) Turn on the unit.
3) Press the Mode button until the LED next to “Dry” lights up.
During the Dehumidifying mode, the unit will condense water out of the air and
exhaust it through the exhaust hose. The ambient temperature in the room will
probably drop by a few degrees while using the Dehumidifying mode.
Notes:
The fan always runs on low speed while in the Dehumidifying mode.
12
If you do not use the exhaust hose in Dehumidifying mode, you must manually drain
the water from the unit. Additionally, the ambient temperature in the room will

probably rise by a few degrees (if you do not use the exhaust hose.)
The Dehumidifying mode will not work in temperatures below 64°F.
Cooling
1) Plug the power cord into a power outlet.
2) Turn on the unit.
3) Press the Mode button until the icon LED next to “Cool” lights up.
4) Select the fan speed by using the Fan button.
5) Set the thermostat using the Temperature / Time buttons. The thermostat is
adjustable between 64°F and 90°F in one degree increments.
Cooling mode cools and dehumidifies your air. If the ambient temperature drops below
the temperature you selected, the compressor turns off and the unit functions with the
fan only. When the temperature rises above the temperature you selected, the
compressor turns on again.
Note:
The exhaust hose must be used in Cooling mode in order to cool a room.
Fan-only
1) Plug the power cord into a power outlet.
2) Turn on the unit.
3) Press the Mode button until the LED next to “Fan” lights up.
4) Select the fan speed by using the Fan button.
Fan-only mode is used to circulate the air in your room. No temperature setting is
needed.
Note:
Fan-only mode does not require that the exhaust hose be attached.
4) Water Drainage
All air conditioners dehumidify the air as they cool. This portable air conditioner is
designed to evaporate and exhaust this condensed water (sometimes called condensate).
When using the Cooling or Dehumidifying modes under extremely humid conditions,
the internal water tray may fill completely. If this happens, the Water Level indicator
on the control panel will light and the compressor will shut off (so that no water is
spilled on the floor.) The unit will continue operating and exhausting water until the
water level lowers. Then the compressor will turn back on and the unit will begin
cooling as normal.
If you want to begin cooling or dehumidifying right away without waiting for the unit
to dispose of the excess condensate itself, you may manually drain the unit.
Manual Drainage
13
Turn the unit off. Unscrew the cap from the upper drain port. Connect a drain hose to
the upper drain port (one is included with this unit, or you may use a garden hose.) Put
the other end of the drain hose in a bucket. Turn the unit back on. The internal drain

pump will pump water into the bucket. When the flow of water stops, you can turn off
the portable air conditioner. Remove the drain hose and reinstall the drain cap. The unit
will now be almost completely drained. If you were draining the unit to allow it to
continue cooling or dehumidifying, simply turn the unit back on to the settings you
want.

Maintenance
14

Make sure the unit is turned off and unplugged before
performing any maintenance.
Do not immerse the unit in water or other liquids.
Do not pour liquids into the unit.
Some parts may have sharp edges. Be careful to avoid
cutting yourself.
1) Filter
This portable air conditioner has a washable pre-filter that filters contaminants out of
the air. This pre-filter should be cleaned about once every two weeks or as needed. If it
becomes clogged with dust, the efficiency of the unit will be lowered.
1) Remove the filter from the filter compartment in the front of the portable air
conditioner.
2) Wash the filter by immersing it in warm water and lightly scrubbing it with a
gentle soap. Do not put the filter in water warmer than 104°F.
3) Rinse the filter thoroughly and dry it. The filter must be completely dry before
it can be put back into the portable air conditioner.
4) Once the filter is completely dry, reinsert it into the unit.
2) Cleaning the Exterior
Wipe the plastic parts with a slightly damp cloth to clean them.
Use stainless steel cleaner to clean the stainless steel panels.
15

3) Long Term Storage
Do wn Dr a i n
Por t
1) On a warm day, run the unit in Fan-only mode for a few hours to
exhaust all condensate and to completely dry out the interior.
2) Turn off the unit and unplug it.
3) Empty any residual condensate water by unplugging the lower
drain port and allowing any water accumulated there to drain
out. Reinstall the rubber stopper after doing this.
4) Detach the exhaust hose and collapse it to its smallest size.
5) Take out the filter. Clean and dry it (see the instructions above),
and reinstall it.
6) Cover the portable air conditioner to protect it from dust. It is
generally a good idea to store the unit in its original box and
packaging.
