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. Once you set the desired function, all functions will be memorized in the unit. The built-in
timer allows from 1 to 12 hours operation, after which the unit is automatically turned on and off. This is espe-
cially 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.
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:
Once the desired function has been set, it is memorized as long as it remains connected to the wall outlet. In
the event of a power failure, the desired function must be re-entered when power is restored.
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 DRAIN TANK IS FULL:
When the drain tank is full, the unit will be automatically shut off. It is always required to press power button
twice to resume operation after the condensed water is removed from the tank.
6. TRIPLE AIR FILTERS:
A pre-filter protects the unit from dust, HAF air filter cleans circulation air and a 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 fan is running at high speed inside. Covering them may
deteriorate air conditioner performance or cause it to become inoper-
ative.
¡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 plug fits 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 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 with filter removed.
CAUTION
¡Keep unit more than 20 in. (50 cm) away from any objects or wall.
(Fig. D)
¡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 blow of the unit.
¡DO NOT ride or place the objects on the unit.
¡DO NOT turn the unit on its side or upside down.

9. FUNCTION
1. Cooling operation
Room temperature setting range is 61 ~ 90˚F (16 ~ 32˚C).
Room temperature indication range is 32 ~ 122˚F (0 ~ 50˚C).
State of operating is as shown below.
A. When the room temperature is 2˚F (1˚C) higher than the setting temperature, the compressor operates at
least for 150 seconds.
If the room temperature drops 2˚F (1˚C) lower than the setting temperature, the compressor stops.
B. For protection of the compressor, it will not restart at least for 150 seconds after it has stopped.
C. In the condition that the Setting temperature +2˚F (+1˚C) > Room temperature > Setting temperature -2˚F
(–1˚C), the compressor operates for more than 150 seconds.
If the room temperature drops more than 2˚F (1˚C) from the setting temperature, the compressor stops.
D. When the room temperature is 2˚F (1˚C) lower than the setting temperature, the compressor will not start.
E. The fan will operate at the selected fan speed.
2. Dehumidifying operation
When the room temperature is lower than 77˚F (25˚C) (setting temperature), the unit enters in the dehumidifying
operation.
