•Do not start/stop operation by plugging/unplugging the power cord.
GROUNDING INSTRUCTIONS
•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.
−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. 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.
−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.

How to Install the Unit
1 To prevent vibration and noise, make sure the
unit is installed securely and firmly.
2 Install the unit out of direct sunlight.
3 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.

CAUTION
•DO NOT cover or block any of the side and top
louvers. All side louvers of the cabinet must
remain exposed to the outside of the structure
and unobstructed.
4 Install the unit slightly tilted so the back is
slightly lower than the front (about 1/2”). This
will force condensed water to flow to the
outside.
5 Install the unit with the bottom between
30”~ 60” above the floor level.
Window Requirements
•This unit is designed for installation in standard
double hung windows with actual opening
widths from 27” to 39”.
The top and bottom window sashes must open
sufficiently to allow a clear vertical opening of
16” from the bottom of the upper sash to the
inside sill.
27” to 39”27” to 39”
16” min16” min
NOTE
•All supporting parts should be secured to firm
wood, masonry, vinyl, fiberglass, or metal.
•This product is a window air conditioner. As
such, a standard single-hung or double-hung
window is required for proper installation. Non-
window installations, including using sleeves or
wall openings, and other installation methods
are not recommended.
Storm Window Requirements
1 Windows that include a storm window frame
may prevent the air conditioner from tilting
down toward the outside to drain properly. For
proper drainage, attach a 2” x 2” piece of wood
to the inner sill, trimmed to a length which fits
inside the window frame. The top of the wood
shim must be at least 1 1/4” higher than the
top of the storm window frame. Attach the
wood securely to the sill with nails or screws.
2 If necessary, attach another 2” x 2” wood strip
flush against the back of the inner sill.

Operation Mode
Press the Mode button to cycle between 4
types of air conditioner operation: Energy
Saver / Cool / Fan / Dry.
Energy Saver - This mode operate as Cool
mode, but saves more energy. When set
temperature isachieved, the compressor and
fan turn off. Approximately every 3 minutes
the fan turns on to allow the unit sensor to
accurately determine if more cooling is needed.
Cool - This mode is ideal on hot days to cool
and dehumidify the room quickly. Use the
Temp buttons to set the desired room
temperature and use the Fan Speed button to
set the desired fan circulation speed.
Fan - In this mode the fan circulates air but the
compressor does not run. Use the Fan Speed
button to set fan speed to High, Medium or
Low. In this mode, you cannot adjust the set
temperature.
Dry - This mode is ideal for rainy and damp
days to dehumidify the room rather than cooling
it significantly. Humidity is removed from
the room by the combination of compressor
operation and the fan speed fixed at Low.
The compressor and fan turn off once the set
temperature is reached. Fan speed cannot be
adjusted in Dry mode.
Sleep Mode
This mode keeps operating noise to a
minimum and turns the air conditioner off
after a set time. The timer can be set from
1 to 12 hours.
•In the Sleep Mode, the setting
temperature increases by 2 °F after
30 minutes and additional 2 °F
after another 30 minutes for a more
comfortable sleep.
•The setting temperature increases up to
4 °F from the preset temperature.
Delay ON/OFF Timer
Delay ON - When the air conditioner is off,
set it to automatically turn on from 1 to 24
hours later, at its previous mode and fan
settings.
Delay OFF - When the air conditioner is
on, set it to automatically turn off from 1 to
24 hours later.

This air conditioner is equipped with a slinger fan.
(See drawing.)
The fan’s outer ring picks up the condensed water
from the base pan if the water level gets high
enough. The water is then picked up by the fan
and expelled through the condenser, making the
air conditioner more efficient.
