Use a dedicated circuit.
Do not use an extension cord.
Do not start/stop operation by plugging/unplugging the power cord.
If the cord/plug is damaged, replace it with only an authorized replacement
part.
Usage
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.
Cleaning and Maintenance
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.
3. When cleaning the unit, first make sure that the power and breaker are turned
off. The fan rotates at a very high speed during operation. There is a
possibility of injury if the unit’s power is accidentally triggered on while
cleaning inner parts of the unit.
Service
For repair and maintenance, contact your authorized service dealer.

ELECTRICAL SAFETY
IMPORTANT GROUNDING INSTRUCTIONS
Air conditioner has a three-prong grounding plug on
its power supply cord, which must be plugged into
properly grounded three-prong wall receptacle for
your protection against possible shock hazard.
230, 208, and 230/208 VOLT UNITS
These units are equipped with a three-prong
grounding plug on the power supply cord, which
must be plugged into a matching properly grounded
three-prong wall receptacle for your protection
against possible shock hazard. If such an outlet is
not present, one must be installed by a qualified
electrician in accordance with the National Electrical
Code and local codes and ordinances.
NOTICE
DO NOT USE AN EXTENSION CORD on 230,
208, and 230/208 Volt units.

IMPORTANT
(PLEASE READ CAREFULLY)
FOR THE USER'S PERSONAL SAFETY, THIS
APPLIANCE MUST BE PROPERLY GROUNDED
The power cord of this appliance is equipped with a
three-prong (grounding) plug. Use this with a standard
three-slot (grounding) wall power outlet to minimize the
hazard of electric shock. The customer should have
the wall receptacle and circuit checked by a qualified
electrician to make sure the receptacle is properly
grounded.
DO NOT CUT OR REMOVE THE THIRD (GROUND)
PRONG FROM THE POWER PLUG.
A. SITUATIONS WHEN THE APPLIANCE WILL BE
DISCONNECTED OCCASIONALLY:
Because of potential safety hazards, we strongly
discourage the use of an adapter plug. However, if you
wish to use an adapter, a TEMPORARY
CONNECTION may be made. Use UL-listed adapter,
available from most local hardware stores.
The large slot in the adapter must be aligned with the
large slot in the receptacle to assure a proper polarity
connection.
: 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. The customer should have
the circuit checked by a qualified electrician to make
sure the receptacle is properly grounded.
Disconnect the power cord from the adapter, using
one hand on each. Otherwise, the adapter ground
terminal might break. DO NOT USE the appliance with
a broken adapter plug.
B. SITUATIONS WHEN THE APPLIANCE WILL BE
DISCONNECTED OFTEN.
Do not use an adapter plug in these situations.
Unplugging the power cord frequently can lead to an
eventual breakage of the ground terminal. The wall
power outlet should be replaced by a three-slot
(grounding) outlet instead.
USE OF EXTENSION CORDS
Because of potential safety hazards, we strongly
discourage the use of an extension cord. However, if
you wish to use an extension cord, use a CSA
certified/UL-listed 3-wire (grounding) extension cord,
rated at 15A, 125V.

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.
Awning
Cooled air
Heat
radiation
30"~60"
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.
Fence
About 1/4"
Over 20"
NOTICE
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.
Installing the Power cord
You can choose between the two methods below according to your preference and window sill
shape.
Using slit "A"
Using slit "B"
• Fasten the stopper using Type A screw, and
pass the power cord through slit "A".
• Fasten the stopper using left screw hole, and
rotate properly to pass the power cord through
slit "B".

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.

Common Problems and Solutions
Before calling for service
If you have problems with your air conditioner, read the following information and
try to solve the problem. If you cannot find a solution, turn off the air conditioner
and contact your dealer.
Air conditioner does not operate
1. Ensure that the air conditioner is plugged into a proper outlet.
2. Check the fuse or circuit breaker.
3. Check whether the voltage is unusually high or low.
Air does not feel cold enough on the cooling setting
1. Ensure that the temperature settings are correct.
2. Check to see if the air filter is clogged with dust. If so, replace the filter.
3. Ensure that the air flow from the outside is not obstructed and that there is a
clearance of over 20" between the back of the air conditioner and the wall or
fence behind it.
4. Close all doors and windows and check for any source of heat in the room.
Before calling for service, please review the following list of common
problems and solutions.
The air conditioner is operating normally when:
• You hear a pinging noise. This is caused by water being picked up by the fan on
rainy days or in highly humid conditions. This feature is designed to help remove
moisture in the air and improve cooling efficiency.
• You hear the thermostat click. This is caused by the compressor cycle starting
and stopping.
• You see water dripping from the rear of the unit. Water may be collected in the
base pan in highly humid conditions or on rainy days. This water overflows and
drips from the rear of the unit.
• You hear the fan running while the compressor is silent. This is a normal
operational feature.
