PRECAUTIONS
CAUTION
Provid occasional ventilation during use.
Be careful to provide adequate ventilation particularly when using the unit in combination with other heating apparatus.
Insufficient ventilation could lead to oxygen starvation.
Do not climb on, or place objects on, the air conditioner.
Personal injury could result from a falling object, or if the unit tips over.
Do not hang on or cover the air conditioner.
Do not expose the air conditioner directly to water.
Electrical insulation could be damaged, resulting in electrical shock.
Do not pull power cord.
Pulling on the cord to disconnect the plug could damage the wires inside the cord, resulting in heat or fire.
Turn off power source when not using the unit for extended periods.
Take precautions to prevent infants from accidentally swallowing batteries.
A battery can be very harmful if swallowed. If an infant accidentally swallows a battery, make the infant eject it, and consult your physician.
Do not direct air flow at fireplaces or heating apparatuses.
Direct air blowing on fires could result in improper combustion or fire.
Do not set flower vases or water containers on top of air conditioners.
Water leaking inside the unit could damage electrical
insulation, leading to danger of electrical shock.
Do not operate the air conditioner with wet hands.
Electrical shock could result.
Always turn off power and disconnect the power plug whenever cleaning the air conditioner or changing the air filter.
A fan operates at high speed inside the unit, and personal
injury could result.

Do not drink the water drained from the air conditioner.
Take out the batteries from the remote control unit when not using for a long time.
Take out the batteries to prevent troubles caused by battery liquid leakage.
If leaking battery fluid comes in contact with your skin, eyes, or mouth, immediately wash with copious amounts of water, and consult your physician.
Always operate with the air filter installed.
Operating the unit without the air filter could cause excessive dirt to collect on internal parts, leading to malfunction.
Install the indoor unit and remote control unit at least one meter from any television sets or radio.
Signal radiation could be induced into the system to give erroneous operation.
When installing the indoor unit and outdoor unit , take precautions to prevent access by infants.
Unexpected accidents could occur.
Avoid to install the air conditioners near the fireplace and heating devices.
The shell of air conditioner may be warped when it is explored at too high temperatwe surroundings.
Do not use in applications involving the storage of foods, plants or animals, precision equipment, or art works.
The quality of the stored items may deteriorate.
Do not touch the heat exchanger radiator fins.
Personal injury could result.
Be particularly careful when cleaning.
Bending or damage to the fins will affect the efficiency of the unit.
Do not block or cover the front panel and outlet port.
Obstructing the ports will reduce operating efficiency, leading to improper operation and possible damage.
Do not inflammable gases near the air conditioner.
For heat pump mode, the temperature of connectors are high. Be careful when operate the system.

¡·
Begin unit operation and confirm that the airflow-direction louvers are stopped before setting the airflow-direction.
WARNING!
¡·
Do not put fingers or other objects into the air louvers; an internal fan operates at high speed and could result in personal injury or damage.
¡·
Do not operate the air conditioner with the airflow louvers blocked, since malfunction could result.

NOTE:
¡·
Always use the remote control unit's airflow-direction button to change the position of the up-down airflow-direction louvers. Do not attempt to set louvers by hand, since it may result in improper operation. In this case, stop the air conditioner temporarily and then restart to return the louvers to proper operation.
¡·
Never operate the air conditioner when the up-down airflow­direction louvers are closed.
¡·
In the cooling and drying modes, dew may condense around
and drop from the air outlet ports when the louvers are set to the other cooling range. As a result, we recommend that this position be used only for brief periods.
¡·
After pressing the remote control unit's airflow-direction button ,a certain time interval may be required unit the louvers are set to the desired position. During the interval, the airflow­direction button will not respond, even if pressed.

Always be sure to disconnect the power plug and turn off your circuit breaker to ensure that power is completely off.
WARNING!
TROUBLE SHOOTING
Before requesting service, perform the following checks:
NORMAL
FUNCTIONS
Doesn't operate immediately:
Symptom
Problem
Noise is heard:
Smells:
Mist or steam are emitted:
Airflow is weak or stops:
¡·
If the unit is stopped and then immediately started again, the 2-way/3-way will not operate for about 3 minutes, in order to prevent fuse blowouts.
¡·
Whenever the power plug is disconnected and then reconnect-
ed to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.
¡·
During operation and immediately after stopping the unit, the
sound of water flowing in the air conditioner's piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation .
¡·
During operation, a slight squeaking sound may be heard. This
is the result of minute expansion and contraction of the front cover due to temperature changes.
¡·
Some smell may be emitted from the indoor unit. This smell is
the result of room smells ( furniture, tobacco, ect. ) which have been taken into the air conditioner.
¡·
During Cooling or Drying operation, a thin mist may be seen to
emit from the indoor unit. This results from the sudden cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.
¡·
The fan may operate at very low speed during Drying mode or
AUTO operation.
¡·
In AUTO operation, the fan will operate at very low speed.
