4.Warning and Cautions
WARNINGS: Following the safety messages is very important .
These
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 .
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 properiy grounded outlet .
We strongly advise against using an adapter plug .

Tips
This air conditioner is designed for use in a double hung window .
Only let a certified electrician modify your electrical outlet .
When installing your air conditioner , make sure to seal all areas where there is a possibility of air leakage.
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 .
The airflow should not be blocked , either inside by curtains , drapes or furniture , or outside by shrubs or
bushes .
Use a dedicated line for the operation of your air conditioner to avoid the possibility of an electrical surge.
The window has to be strong for installation . Extra brackets and/or support may be required depending
on your window .(Brackets and supports not included in all models .)
Install the unit on the north side , as that is normally the shaded side . This will enhance the operation
of your unit .
While installing unit be sure to tilt air conditioner 5 degrees outward to have the water drip outside the
house .
Measure 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 .
Energy Saving Guide

5. Installation and Accessory Parts
Check the following before you install your air conditioner:
1) The unit is free of all obstructions inside and outside the room e.g. drapes, curtains, furniture, plants,
shrubs, bushes, trees, other structures like building, garage etc.
Air conditioner must have clear unobstructed airflow through the condenser to remove the heat.
2) The window is strong enough to hold the weight of the air conditioner. Extra brackets or supports may be
needed depending on your windows. Brackets or supports not not provided in all models.
3) The window sill and track are strong enough to hold the weight of the air conditioner.
4) The wall is strong enough to hold the unit. Extra brackets or supports may be needed depending on the
wall. (Brackets or Supports not provided in all models).
5) There is adequate and proper power supply near the air conditioner.
6) DO NOT use adopter plugs.
7) DO NOT use extension cords.
8) DO NOT cut or remove the ground prong.
9) DO NOT modify the plug or the electrical wall outlet in any way. If plug does not fit the electrical outlet
have a certified electrician do the necessary change.
10) NOT connect electrical power to the unit before installation.
11) DO NOT use if power cord is worn out, hayed or damage. Avoid using if here are cracks or abrasion
damage along the length, plug or connection.
12) Be careful of exposed sharp edges of the cabinet and sharp coils (fins) on the back of the unit that could
cut and cause serious injury.

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 t he 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 fo r the required cooling area.
On extreme hot & humid days, air conditi oners 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, co mpressor 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 condi tioner 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.
