1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can
destroy the insulation, leading to possible electric shock.

off. The fan rotates at a very high speed during operation. There is a
possibility of injury if the unit’s power is accidentally triggered on while
cleaning inner parts of the unit.

IMPORTANT
(PLEASE READ CAREFULLY)
FOR THE USER'S PERSONAL SAFETY, THIS
APPLIANCE MUST BE PROPERLY GROUNDED
The power cord of this appliance is equipped with a
three-prong (grounding) plug. Use this with a standard
three-slot (grounding) wall power outlet to minimize the
hazard of electric shock. The customer should have the
wall receptacle and circuit checked by a qualified
electrician to make sure the receptacle is properly
grounded.
DO NOT CUT OR REMOVE THE THIRD (GROUND)
PRONG FROM THE POWER PLUG.
A. SITUATIONS WHEN THE APPLIANCE WILL BE
DISCONNECTED OCCASIONALLY:
Because of potential safety hazards, we strongly
discourage the use of an adapter plug. However, if you
wish to use an adapter, a TEMPORARY CONNECTION
may be made. Use UL-listed adapter, available from
most local hardware stores.
The large slot in the adapter must be aligned with the
large slot in the receptacle to assure a proper polarity
connection.
: Attaching the adapter ground terminal to the wall
receptacle cover screw does not ground the appliance
unless the cover screw is metal, and not insulated, and
the wall receptacle is grounded through the house
wiring. The customer should have the circuit checked
by a qualified electrician to make sure the receptacle
is properly grounded.
Disconnect the power cord from the adapter, using one
hand on each. Otherwise, the adapter ground terminal
might break. DO NOT USE the appliance with a broken
adapter plug.
B. SITUATIONS WHEN THE APPLIANCE WILL BE
DISCONNECTED OFTEN.
Do not use an adapter plug in these situations.
Unplugging the power cord frequently can lead to an
eventual breakage of the ground terminal. The wall
power outlet should be replaced by a three-slot
(grounding) outlet instead.
USE OF EXTENSION CORDS
Because of potential safety hazards, we strongly
discourage the use of an extension cord. However, if
you wish to use an extension cord, use a CSA
certified/UL-listed 3-wire (grounding) extension cord,
rated at A, 25V.
