Operation of Safety Plug
Your window air conditioner is supplied with a Leakage-Current Detection and
Interruption (LCDI) safety plug. This device provides protection to reduce the risk
of fire due to arcing faults in the power supply cord. Before using your window air
conditioner, follow the instructions below to ensure that the LCDI plug is working
properly:
1. Plug the power cord to a grounded outlet.
2. Press the TEST button on the LCDI plug. This should trip the plug and cut the
power to the air conditioner. If the plug does not trip and you are able to turn on
the unit, please contact EdgeStar support.
DO NOT USE YOUR WINDOW AIR CONDITIONER IF THE TEST FAILS.
3. Press the RESET button to start using your air conditioner.
NOTES:
Always make sure the “Reset” button is pushed in for proper
operation.
The power supply cord with LCDI plug must be replaced if it fails to
reset.
Do not use the TEST and RESET buttons as an ON/OFF switch.
Electrical products should not be disposed of with household waste.
Please contact your local recycling center for more information on how to
recycle electronic waste.

Maintenance
Clean the air conditioner and filters regularly to maximize
performance and efficiency, and prolong the unit’s life. Be sure to
always unplug the air conditioner from the power outlet before
cleaning to prevent injury or damage to person or property.
Air Filter Cleaning
The air filter should be checked at least once a month to see if
cleaning is necessary. Trapped particles in the filter can build up
and potentially cause an accumulation of frost on the cooling coils.
1. Push the vent handle to the “vent closed” position.
2. Open the front panel.
3. Grasp the filter, pull up and out.
4. Wash the filter using liquid dishwashing detergent and
warm water. Rinse filter thoroughly.
5. Gently shake excess water from the filter. Be sure the
filter is thoroughly dry before replacing.
6. You also have the option of cleaning the filter with a
vacuum.
Warning: Never use hot water over 40°C (104°F) to clean
the air filter. Never attempt to operate the unit without the air
filter.
Cabinet Cleaning
Be sure to unplug the air conditioner to prevent injury or
damage to person or property. The cabinet and front may
be dusted with an oil-free cloth or wiped with a damp
wash cloth. Rinse thoroughly and wipe dry.
Never use harsh cleaners, wax, or polish on the cabinet
front.
Be sure to wring out excess water from the cloth before
wiping around the controls. Excess water in or around the
controls may cause damage to the air conditioner.

Normal Sounds
High Pitched Chatter- High efficiency compressors may have
a high pitched chatter during the cooling cycle.
Sound of Rushing Air- At the front of the unit, you may hear
the sound of rushing air being moved by the fan.
Gurgle/Hiss- Gurgling or Hissing noise may be heard due to
refrigerant passing through evaporator during normal
operation.
Vibration- Unit may vibrate and make noise because of poor
wall or window construction or incorrect installation.
Pinging or Switching- Droplets of water hitting condenser
during normal operation may cause these sounds.
Energy Saving Guide
Read and follow the guide below to get the most efficient
performance from your window air conditioner:
Do not cover the air outlet (exhaust) while in use.
Use the timer to operate the unit before it is needed. For
example, set the timer to turn on the unit in cooling mode for 3
or more hours to cool the room before you arrive. You may want
to operate the unit all day if you live in a warmer climate.
Minimize the heat sources (direct sunlight, computers, servers,
people, etc.) in the room.
Close all windows and doors.
Use the unit in a contained room. For example, a room with four
walls and a ceiling, instead of a partitioned studio, or
warehouse.
Make sure the unit is secure with no gaps where air can escape.
Minimize the amount of humidity in the room. For example, run
the unit as a dehumidifier.
To prolong the compressor's life, please wait at least 3 minutes
before turning the unit back on after shutting it off.
Inspect and keep the air filters clear by cleaning regularly.
Perform routine maintenance.
