6. Parts and Functions
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 61oF and 86o 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 AC 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 side-left side.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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. Occasionally 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.
