1. THE SUMMARY
The idea behind the unit is to provide a localized supply of cool air.
The unit will greatly enhance your personal comfort whether at a work station or even in your favorite chair.
Four (4) casters enable you to move the unit easily from room to room. It cools and dries the air at the same
time so that you can stay comfortable even when it's humid or rainy outside. Also your furnishings and fabrics
are kept in good condition when it's used as dehumidifier.
Conventional air conditioners use large quantities of energy to cool an entire room, including walls and furni-
ture. This unit creates a zone of cool and dry air only where it is needed. It does not waste energy cooling the
surroundings.
It's easy to operate. The built-in timer allows from 1 to 12 hours of operation, which will automatically turn the
unit on and off. This is especially convenient at bedtime.
Venting is not required. However, if the unit is to be used exclusively in one space, the cooling efficiency will be
enhanced by using the venting kit accessory, which is included with the unit.
2. OPERATIONAL FEATURES
1. COOLING OPERATION:
Normally, cool air is directed out the front louvers by the circulation fan which has three (3) stages of fan
speed.
2. AUTOMATIC OPERATION:
The unit will select its mode and fan speed automatically base on the environment temperature.
3. THERMO CONTROL
The compressor will automatically shift to ON or OFF to maintain the desired temperature.
4. TIMER OPERATION:
The unit will turn on and off after the designated period of time (1, 2, 3, ...12 hours).
5. AUTOMATIC SHUT-OFF MECHANISM WHEN THE DRAIN TANK IS FULL:
When the drain tank is full, the unit will be automatically shut off. It is always required to press the power
button twice to resume operation after the condensed water is removed from the tank.
6. TRIPLE AIR FILTERS:
The pre-filter protects the unit from dust, the HAF air filter (option) cleans circulation air and the charcoal
filter eliminates unpleasant odor.

5. SAFETY TIPS
IMPORTANT
¡Read instructions carefully before operation.
¡The unit should be operated when the room temperature is between 64˚F (18˚C) to 95˚F (35˚C). If the room
temperature is below 64˚F (18˚C), ice may form on the coils. If the room temperature is above 95˚F (35˚C), the
compressor will automatically shut off to protect itself.
¡ALWAYS, wait 3 min. to restart after turning unit off.
WARNING
¡NEVER expose infants, handicapped persons, or senior persons
directly to the airflow. Adjust the airflow direction.
¡Keep children away from unit. Children are particularly liable to this
danger. The inside fan is running at high speed. Covering it may dete-
riorate air conditioner performance or cause it to become inoperative.
¡NEVER insert objects of any kind into the air intake or air outlet.
¡DO NOT unplug if your hands are wet. An electrical shock may occur.
¡DO NOT operate in a wet location.
¡ALWAYS plug into 115 V, 60 Hz, single phase electrical outlet.
¡Be sure the power plug fits the receptacle securely.
¡DO NOT run power cord under carpets, rugs, or floor mats of any
kind.
¡DO NOT attempt to shorten or alter power cord in any way.
¡DO NOT apply any excessive force or pressure to the power supply
cord.
¡Make sure that the plug is free of dust.
¡DO NOT use an extension cord.
¡DO NOT turn on and off by inserting or removing the power plug
which may cause electric shock or fire.
¡If there is a fear of lightning, stop the unit and disconnect the power
supply cord.
¡DO NOT touch the evaporator, condenser and pipes.
¡DO NOT operate without filter.
¡ALWAYS lift the unit with the help of another person.
CAUTION
¡Keep unit more than 20 in. (50 cm) away from any objects or wall.
¡If the unit is operated in COOL mode in an area of very high moisture,
the top plate and the rear plate may get covered with a mist. Wipe off
any mist before it has a chance to get on the floor or rug.
¡Remove drain water before moving unit.
¡To minimize corrosion, DO NOT use in damp, salty air area.
¡DO NOT operate in direct sunlight.
¡DO NOT use for such particular purpose as preservation of foodstuff,
animals, plants, precision appliances, arts and medicine.
¡DO NOT place an animal, plants or combustion equipment in a place
which is subjected to the direct air flow of the unit.
¡DO NOT ride or place the objects on the unit.
¡DO NOT turn the unit on its side or upside down.
