Safety Precautions
• Thoroughly read the following safety precautions prior to use.
• Observe these precautions carefully to ensure safety.
WARNING
CAUTION
IMPORTANT
All electric work must be performed by personnel certified by Mitsubishi Electric.
General
WARNING
Do not use refrigerant other than the type indicated 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.
• MITSUBISHI ELECTRIC CORPORATION cannot be held
responsible for malfunctions or accidents 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
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.
CAUTION
To reduce the risk of fire or explosion, do not place flammable
materials or use flammable sprays around the unit.
Indicates a risk of death or serious injury
Indicates a risk of injury or structural damage
Indicates a risk of damage to the unit or other components in the system
To reduce the risk of burns or frost bites, do not touch the
refrigerant pipes or refrigerant circuit components with bare
hands during and immediately after operation.
Before cleaning the unit, switch off the power.
(Unplug the unit, if it is plugged in.)
To reduce the risk of injury, keep children away while
installing, inspecting, or repairing the unit.
Children should be supervised to ensure that they do not play
with the appliance.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
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.
Always replace a fuse with one with the correct current
rating.
The use of improperly rated fuses or a substitution of fuses
with steel or copper wire may result in fire or explosion.
If any abnormality (e.g., burning smell) is noticed, stop
the operation, turn off the power switch, and consult
your dealer.
Continuing the operation may result in electric shock,
malfunctions, or fire.
Properly install all required covers and panels on the
terminal box and control box to keep moisture and dust
out.
Dust accumulation and water may result in electric shock,
smoke, or fire.
Consult an authorized agency for the proper disposal of
the unit
Refrigerant oil and refrigerant that may be left in the unit pose
a risk of fire, explosion, or environmental pollution.
Do not operate the unit without panels and safety guards
properly installed.
