General precautions
WARNING
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.
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.
To reduce the risk of electric shock, malfunctions,
smoke or fire, do not operate the touch panel 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 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 panel 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.
Relocation and repairs
WARNING CAUTION
The controller should be repaired or moved only
by qualified personnel. Do not disassemble or
modify the controller.
Improper installation or repair may cause injury,
electric shock, or fire.
To reduce the risk of shorting, electric shock, fire,
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
To avoid damage to the controller, use
appropriate tools to install, inspect, or repair the
controller.
This controller is designed for exclusive use with
