4. Do not use an extension cord.
5. Do not start/stop operation by plugging/unplugging the power cord.
6. If the cord/plug is damaged, replace it with only an authorized replacement
part.
1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can
destroy the insulation, leading to possible electric shock.

Electrical Safety
WARNING: This appliance must be properly grounded.
The power cord of this appliance is equipped with a three-prong grounding plug.
To minimize the risk of electric shock, use the plug with a standard three-slot
grounding wall power outlet. If the power outlet does not include a grounding slot,
have a qualified electrician replace the outlet before you use the room air
conditioner.
WARNING: Do not cut or remove the grounding prong from the power
plug.
WARNING: Attaching the adapter ground terminal to the wall
receptacle cover screw does not ground the appliance unless the
cover screw is metal and not insulated, and the wall receptacle is
grounded through the house wiring.
WARNING: If you have any doubt whether the air conditioner is
properly grounded, have the wall receptacle and circuit checked by a
qualified electrician.
Preferred method
Ensure proper ground
exists before use
Electrical Safety

10 Room Air Conditioner
Electrical Safety
We strongly discourage the use of an adapter due to potential safety hazards.
For temporary connections, use only a UL-listed adapter, available from most
local hardware stores. Ensure that the large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the power cord as
this can lead to eventual ground terminal damage.
WARNING: Never use the appliance with a broken adapter.
We strongly discourage the use of an extension cord due to potential safety
hazards. For temporary situations, use only CSA certified and UL listed 3-wire
grounded extension cords, rated 15 A, 125 V.

Installation
How to Install the Unit
1.To prevent vibration and noise, make sure the
unit is installed securely and firmly
2. Install the unit where the sunlight does not
shine directly on the unit.
3.The outside of the cabinet must extend outward
for at least 14" and there should be no
obstacles, such as a fence or wall, within 20"
from the back of the cabinet because it will
prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the
cooling efficiency of the air conditioner.
All side louvers of the cabinet must remain exposed to the outside of the structure.
4. Install the unit at a slight incline so the back is slightly lower than the front(about 1/4").
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 30"~60" above the floor level.

Casement Window Installation
1. Installation procedure is the same as that described in steps 1 through 11 and step 13 of the
Horizontal Sliding Window installation.
2. If the window opening is wider than 15-3/4 inches you will need to install a filler panel. Make this
panel from 3/4 inch thick wood and run it the full length of the window.
Attach it securely to the window frame and paint it to protect it from the weather.
3. Since styles and sizes of casement windows vary widely, it is advisable to have the air conditioner
installed by someone skilled in this type of installation.
