General Precautions
Do not use refrigerant other than the type in-
dicated in the manuals provided with the
unit and on the nameplate. Doing so may
cause the unit or pipes to burst, or result in
explosion or fire during use, during repair,
or at the time of disposal of the unit. It may
also be in violation of applicable laws. MIT-
SUBISHI ELECTRIC CORPORATION cannot
be held responsible for malfunctions or ac-
cidents resulting from the use of the wrong
type of refrigerant.
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 fre-
quently. These substances can compro-
mise the performance of the unit or cause
certain components of the unit to corrode,
which can result in refrigerant leakage, wa-
ter leakage, injury, electric shock, malfunc-
tions, 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 de-
feating the safety features of the devices
such as the pressure switch or the tempera-
ture switch, making unauthorized changes
to the switch settings, or using accessories
other than the ones recommended by Mit-
subishi Electric may result in smoke, fire, or
explosion.
To prevent the risk of injury from falling
tools or work materials, before starting in-
stallation work, inspection, or repair work,
check the surroundings and make sure to
keep children away from the work area.
To reduce the risk of refrigerant leakage,
water leakage, injury, electric shock, or fire,
do not alter or modify the unit.
To reduce the risk of bursting, fire or explo-
sion, only use fuses with the specified
breaking capacity. Do not substitute wire or
copper wire for a fuse.
To reduce the risk of shorting, current leak-
age, electric shock, malfunctions, smoke, or
fire, do not wash the unit with water or any
other liquid.
