Warning and Cautions
4.Warning and Cautions
WARNINGS: Following the safety messages is very important.
These messages can save you from being injured or killed. Warning symbols alert you to be
careful and means Danger . Always follow instructions to be safe and reduce chances of injury
or death . Warning and Danger signs will precede safety messages.
Electrical Safety
GROUNDING: This room air conditioner must be grounded. Grounding reduces the risk of electric shock by
providing an escape wire for the electric current. The power cord has a grounding wire with a
grounding plug . Plug it into an outlet that is properly installed and grounded.
WARNING:
Improper use of the grounding plug can result in a risk of electric shock.
Call a qualified electrician if you don’t understand the grounding instructions or if you are not sure
if the air conditioner is properly grounded. If the wall outlet is not grounded, please contact an
electrician to have it replaced with a proper grounded outlet.
Do not, under any circumstances, cut or remove the third (ground) prong from the
power cord.
Adapter Plug: We strongly advise against using an adapter plug.

Warning and Cautions
TIPS
This air conditioner is designed for use in a double hung window.
While installing unit be sure to tilt air conditioner 5 degrees outward to have the water drip outside the house.
Install the unit on the north side, as that is normal the shaded side. This will enhance the operation of your unit.
The window has to be strong for installation. Extra brackets and/or support may be reqired depending on your
window. (Brachets and supports not included in all models.)
Masure the window before installing. If the window is too big for the unit, you may require professional installation.
Use the correct electric voltage and proper ampere for the unit to run effectively.
Only let a certified electrician modify your electrical outlet.
Use a dedicated line fot the operation of your air conditioner to avoid the possibility of an electrical surge.
Energy Saving Guide
When installing your air conditioner, make sure to seal all areas where there is a possibility of air leakage.
The airflow should not be blocked either inside by curtains, drapes or furniture, or outside bu shrubs or bushes.
Do not needlessly use electrical light or other appliances that produce heat.
Keep the blinds and drapes drawn on all other windows.
While cooking, use an exhaust fan in the kitchen to remove the excess heat.
Always use the correct BTU size air conditioner to cool the room to attain optimum efficiency.

Abnormity Diagnose
7. Abnormity Diagnose
If air conditioner does not operate:
Check if unit is plugged in. The plug may have come loose.
Check if the unit is in the :Off” mode.
Air from air conditioner is warm:
The A/C setting may need to be raised.
Ice formation on cooling coils:
The outside temperature is too cold. Set the unit on “fan only” setting to defrost ice.
The temperature setting may be too cold.
The unit BTU may be too high for the room.
Air conditioner is working but room is not cooling:
The room may have appliances that produce heat. Use an exhaust fan to remove excess heat.
Redirect the airflow. Remove any obstacles.
All doors and windows need to be closed so cool air does not escape the room.
The air filter may need cleaning.
The unit BTU may be too low for the required cooling area.
On extreme hot & humid days, air conditioners may take a little longer to cool.
Vent may be in the open position. Vent has to be closed for optimum cooling.
Air conditioner is making noise when cooling:
You may hear sounds of air movement, water, compressor clicking on and off or window vibrations.
Please read Operating Guide - Normal Operating Sounds.
Water in the air conditioner cabinet:
This is normal, as your air conditioner not only cools but also dehumidifies the air. If there is water dripping
inside the room, check the installation of the unit. The unit may need to be reinstalled.
