CAUTION
Indicates a risk of injury or structural damage
IMPORTANT
Indicates a risk of damage to the unit or other components in the system
■General
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 containing sulfur 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 refrigerant leakage, water leakage,
injury, electric shock, malfunctions, smoke, or
fire.
Do not try to defeat the safety features of
the unit or make unauthorized setting
changes.
Forcing the unit to operate the unit by
defeating the safety features of the devices
such as the pressure switch or the temperature
switch, making unauthorized changes to the
switch settings, or using accessories other
than the ones recommended by Mitsubishi
Electric may result in smoke, fire, or explosion.
To reduce the risk of fire or explosion, do not
use volatile or flammable substances as a heat
carrier.
To reduce the risk of burns or electric shock,
do not touch exposed pipes and wires.
To reduce the risk of shorting, current leakage,
electric shock, malfunctions, smoke, or fire, do
not splash water on electric parts.
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 electric shock and injury
from the fan or other rotating parts, stop the
operation and turn off the main power before
cleaning, maintaining, or inspecting the unit.
To reduce the risk of burns or frost bites, do
not touch the pipes or refrigerant circuit
components with bare hands during and
immediately after operation.
To reduce the risk of injury, keep children away
while installing, inspecting, or repairing the
unit.
Keep the space well ventilated.
Refrigerant can displace air and cause oxygen
starvation. If leaked refrigerant comes in
contact with a heat source, toxic gas may be
generated.
