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. You
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.
You 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. You have
3 levels of Fan Speed to set at your desired
comfort level: HIGH, MED and LOW.

3. Function

Your 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
You 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) DEHUMIDIFY
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. You can use this feature
alone in case you do not wish to use the air
conditioner.
d) ENERGY 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

Your 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 Air 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 side­left 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

Your air conditioner becomes more versatile
with this feature. You 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.
You 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.

8

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.
