BEFORE USING YOUR AIR CONDITIONER
PREPARING FOR OPERATION
Refer to the Installation Instructions included in
this manual before using the air conditioner.
Once the air conditioner has been properly
assembled and installed:
Plug the power cord into its own dedicated
1
properly grounded outlet. You will hear a
tone to confirm that the conditioner is
plugged in. Do not plug other appliances
into the same outlet; it could overload the
outlet and create a fire hazard.
Make sure the air conditioner and cord is
2
positioned where it does not create a
tripping hazard and will receive adequate
ventilation. Do not place it directly next to
furniture or objects that could block the
vent openings.
Make sure that any items that could be
3
blown over or damaged by the airflow from
the fan are out of the airflow path.
UNPACKING THE AIR CONDITIONER
Remove and store packing materials for reuse.
Remove any shipping tape before using the
air conditioner. If the tape leaves behind any
adhesive, rub a small amount of liquid dish
soap onto it and wipe with a damp cloth. Do
NOT use sharp instruments, alcohol, thinners,
or abrasive cleaners to remove adhesive.
They could damage the finish.
IMPORTANT:
• Do not remain in the direct airflow from the air
conditioner for extended periods of time.
• To prevent damage or injury to pets and
plants, make sure they are not exposed to
direct airflow from the air conditioner.
• When used at the same time as stoves,
fireplaces, and other combustion devices,
make sure there is a sufficient flow of fresh air
into the room. Do not use in tightly enclosed
spaces with these types of devices.
• This air conditioner is intended for household
use as a consumer comfort appliance. Do not
use it as a precision climate control system,
or for purposes such as cooling precision
equipment, food, pets, plants, artwork, etc.
Such items could be damaged.
• Do not bend the hose downward when
window installation kit is not applied. It may
cause failure of air conditioner or performance
deterioration.
