smoke or fire, do not operate the switches/buttons or
touch other electrical parts with wet hands.
When disinfecting the unit using alcohol, ventilate
the room adequately. The fumes of the alcohol
around the unit may cause a fire or explosion when
the unit is turned on.
To reduce the risk of injury or electric shock, before
spraying a chemical around the controller, stop the

To reduce the risk of injury or electric shock, stop
the operation and switch off the power supply before
cleaning, maintaining, or inspecting the controller.
If any abnormality (e.g., burning smell) is noticed,
stop the operation, turn off the power switch, and
consult your dealer. Continued use of the product
may result in electric shock, malfunctions, or fire.
Properly install all required covers to keep moisture
and dust out of the controller. Dust accumulation and
water can cause electric shock, smoke, or fire.
CAUTION
To reduce the risk of fire or explosion, do not place
flammable materials or use flammable sprays
around the controller.
To reduce the risk of damage to the controller, do not
directly spray insecticide or other flammable sprays
on the controller.
4
To reduce the risk of environmental pollution, consult
an authorized agency for proper disposal of remote
controller.
To reduce the risk of electric shock or malfunctions,
do not touch the touch panel, switches, or buttons
with a pointy or sharp object.
To reduce the risk of injury and electric shock, avoid
contact with sharp edges of certain parts.
To avoid injury from broken glass, do not apply
excessive force on the glass parts.
To reduce the risk of injury, wear protective gear
when working on the controller.

temperature.
The Night setback function is not available if the operation and the temperature setting are performed
from the remote controller.
If the room temperature is measured by the air-conditioner's suction temperature sensor, the accurate
temperature may not be obtained when the air-conditioner is inactive or when the air is not clean. In
this case, switch the sensor to a remote sensor (PAC-SE40TSA/PAC-SE41TS-E) or a remote control
