General precautions
To reduce the risk of electric shock, malfunctions,
smoke or fire, do not operate the switches/buttons or
touch other electrical parts with wet hands.
To reduce the risk of shorting, current leakage,
electric shock, malfunctions, smoke, or fire, do not
wash the controller with water or any other liquid.
Do not install the unit in a place where large
amounts of oil, steam, organic solvents, or corrosive
gases, such as sulfuric gas, are present or where
acidic/alkaline solutions or sprays are used
frequently. These substances can compromise
the performance of the unit or cause certain
components of the unit to corrode, which can result
in electric shock, malfunctions, smoke, or fire.
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
operation and cover the controller.
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.
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 display or buttons with a
pointy or sharp object.

Eng-5

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.
Precautions for moving or repairing the controller

or malfunction, do not touch the circuit board with
tools or with your hands, and do not allow dust to
accumulate on the circuit board.
Additional precautions
