1.Thermostat
This allows you to adjust the temperature of the
air--the lower the setting,the cooler the air
temperature. With this you can set the
temperature to your desired comfort level. ou
can set the temperature between 61 F and 86
F.
2.Fan Speed
With this you can control the fan speed as well
as the A/C (cooling) speed.
ou have 3 levels of A/C Speed to set at your
desired level. LO will circulate air at the lowest
velocity, MED at medium velocity and HIGH
will circulate at the maximum, velocity. ou have
3 levels of Fan Speed to set at your desired
comfort level: HIGH, MED and LOW.
3. Function
our air conditioner has 4 Functions.
a) COOL
Here the air conditioner will operate the
compressor and the desired fan speed set to
give you cold air for your comfort.
b) FAN
ou can run the fan without the A/C function
on cooler days. The fan can be set to run at
3 speeds as desired.
c) DEHUMIDIF
This enables your air conditioner to operate as
a dehumidifier as well. It will remove the excess
moisture from the air to keep your room at a
comfortable, dry stage. ou can use this feature
alone in case you do not wish to use the air
conditioner.
d) ENERG SAVER
When this feature is "On" , the fan will shut off
three minutes after the compressor cycles off.
This will reduce energy consumption and noise.
When the compressor turns back on, the fan
will turn on at the same time. In the "Off"
position, the fan will not shut off when the
compressor cycles off.
4.Timer
our air conditioner can be set to go on or off
at your desire. This can be programmed up to
24 hours in advance.
5.4-Way ir Flow
The air directional louvers let you control the
direction of the airflow to the desired direction.
The airflow can be directed up-down-right side-
left side.

7
6.Vent
The Fresh Air vent allows the air conditioner
to recirculat inside air, draw fresh air into the
room and exhaust stale air to the outside.
7.Slide Out Chassis
our air conditioner becomes more versatile
with this feature. ou have the option to install
the unit in a window or the wall.
8. Window Install Kit
This kit enables you to install the air conditioner
in a double hung window. Extra brackets or
support may be needed, depending on your
window.
9.Remote Control
This fully functional wireless remote allows you
to operate your air conditioner from a distance.
ou need not get up to change the settings or
the functions, or to turn the unit on or off.
10.LED Display Electronic Control Panel
The 4-function LED displays Room Temperature,
Temperature Setting, Timer Setting and Time
Remaining to Stop/Start the unit. Electronic
Control Panel lets you set the temperature to
the exact temperature you desire.
11.Electrostatic Filter (not all models)
Being constructed of high efficiency purifying
substance, active carbon fabric, electrostatic
fabric, electrostatic active carbon net and other
materials, this air conditioner purifies the air
effectively. Its wavy structure increases the
capability to filter dust and smoke effectively.
Due to the retention of active carbon, it has
a high purifying speed capable of strong airflow.
12. How The Unit Drains
On humid days with the air conditioner in use,
moisture may collect on the pan or the bottom
of the air conditioner. If the unit is positioned
properly, the moisture will gather towards the
back of the unit.This will not affect the operation
of the unit and the moisture will evaporate in
time. Occasionaly the moisture will flow over
the back of the pan, but this will not affect the
operation of the unit. Never drill holes in the
pan under any circumstance.

Cool airflow movement as dictated by the set fan speed.
Water sounds. This is normal since your air conditioner also acts as a dehumidifier.
Thus you will hear water sounds from water drops falling on the condenser.
As the refrigerant flows through the inner sealed tubing, a rushing noise may be
occur.
Rattling or vibrating noises may be heard due to poor wall or window installation.
High pitch compressor sound may be heard.
After installing your air conditioner, plug it into the proper electrical outlet in the
wall. Keep the vent in the closed position. Now set the air conditioner at your
comfort level. This fully functional wireless remote allows you to operate your air
conditioner without having to get up and go to the unit. The full function feature
allows you to change the settings and turn the unit on or off from the remote itself.
This control pad works the same as the control pad on the air conditioner. (See
Fig. #1)
The following sounds are normally heard during the operation of an air conditioner.

Before you install your air conditioner, check the following:
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 buildings, garage, etc.
The air conditioner must have a clear, unobstructed airflow through the condenser to
remove 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
provided in all models)
3) The windowsill and track are strong enough to hold the weigh 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 adapter 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) DO NOT connect electrical power to the unit before installation.
11) DO NOT use if power cord is worn out, frayed or otherwise damaged. Avoid using
if there 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

Installing Unit into Window
Window Opening Requirements
The air conditioner is designed to fit into double or single hung sash type windows. Each of the
units comes with an installation kit that provides adjustable mounting louvers to fill the gaps
between the sides of the unit and the window frame. The chart below reflects the dimensions of
the units with and without installation kits. Measure your window opening width and compare it
to the chart below to ensure that it meets the minimum and maximum window width requirements.

Install top rail with four 13/32" screws.
Slide left-hand curtain assembly into
left end of top and bottom rails. Repeat
for right-hand curtain assembly. Fasten
curtain retainer strips to the sides of
the outer case with six 13/32" screws.

Add wood strip (at least 1 1/2" wide)
along entire width of window sill.
Thickness of wood strip should match
height of front lip on window frame.
Fasten wood strip to sill with a
minimum of three countersunk wood
screws (not supplied with kit). This
provides a smooth surface for
mounting air conditioner.
Storm window installation
If storm window frame does not allow
adequate clearance below sill (1/2"
required), remove storm window
frame or create clearance by adding a
wood strip (at least 1 1/2" wide) along
entire width of sill. Fasten wood strip
to sill with at least three countersunk
wood screws (not supplied with kit).
This provides a smooth surface for

Install sash bracket on top of indoor window sash
with one wood screw 31/32" to prevent raising of
window from the outside. Screw the anchor directly
into the side of window frame. For hard wood or
metal window frames, drill a pilot hole to start the screw.
Important:Be careful not to drill the pilot hole too deep.
Add a piece of tape to the drill bit as a depth gauge.
Also stay clear of glass. Be careful not to damage the
function of the window.
Cut window seal gasket to width of window. Stuff window
seal strip between the outdoor window glass and the top of
the indoor sash. This will stop air leakage which reduces
efficiency.

Caution:
Find someone to help you replace
the chassis in outer case. Replace
front panel and grille.
For security purposes, reinstall screws
at cabinet's sides, removed in step
one.
Because the window sash helps keep
the unit in window, make certain the
window sash contacts the outer case
before reinstalling the chassis.
