• This appliance is intended to be used by expert or trained users in shops,
in light industry and on farms, or for commercial use by lay persons.
• Do not use refrigerant other than the type indicated in the manuals pro-
vided 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.
• Ask the dealer or an authorized technician to install the air conditioner.
- Improper installation by the user may result in water leakage, electric shock,
or fire.
• Install the unit at a place that can withstand its weight.
- Failure to do so may cause the unit to fall down, resulting in injuries and
damage to the unit.
• Use the specified cables for wiring. Make the connections securely so that
the outside force of the cable is not applied to the terminals.
- Inadequate connection and fastening may generate heat and cause a fire.

• Prepare for earthquakes and install the unit at the specified place.
- Improper installation may cause the unit to fall down and result in injury and
damage to the unit.
• Always use accessories specified by Mitsubishi Electric.
- Ask an authorized technician to install the accessories. Improper installation
by the user may result in water leakage, electric shock, or fire.
• Never repair the unit. If the air conditioner must be repaired, consult the
dealer.
- If the unit is repaired improperly, water leakage, electric shock, or fire may
result.
• Do not touch the refrigerant pipes.
- Improper handling may result in injury.
• When handling this product, always wear protective equipment.
EG: Gloves, full arm protection namely boiler suit, and safety glasses.
- Improper handling may result in injury.
• If refrigerant gas leaks during installation work, ventilate the room.
- If the refrigerant gas comes into contact with a flame, poisonous gases will
be released.
• Install the air conditioner according to this Installation Manual.
- If the unit is installed improperly, water leakage, electric shock, or fire may
result.
• Have all electric work done by a licensed electrician according to "Electric
Facility Engineering Standard" and "Interior Wire Regulations"and the in-
structions given in this manual and always use a dedicated power supply.
- If the power source capacity is inadequate or electric work is performed
improperly, electric shock and fire may result.
• Keep the electric parts away from water (washing water etc.).
- It might result in electric shock, catching fire or smoke.
• Securely install the cover of control box.
- If the cover is not installed properly, dust or water may enter the outdoor
unit and fire or electric shock may result.
• When installing and moving the air conditioner to another site, do not
charge it with a refrigerant different from the refrigerant specified on the
unit.
- If a different refrigerant or air is mixed with the original refrigerant, the
refrigerant cycle may malfunction and the unit may be damaged.
• If the air conditioner is installed in a small room, measures must be taken
to prevent the refrigerant concentration from exceeding the safety limit if
the refrigerant should leak.
- Consult the dealer regarding the appropriate measures to prevent the
safety limit from being exceeded. Should the refrigerant leak and cause the
safety limit to be exceeded, hazards due to lack of oxygen in the room
could result.
• When moving and reinstalling the air conditioner, consult the dealer or an
authorized technician.
- If the air conditioner is installed improperly, water leakage, electric shock, or
fire may result.
• After completing installation work, make sure that refrigerant gas is not
leaking.
- If the refrigerant gas leaks and is exposed to a fan heater, stove, oven, or
other heat source, it may generate noxious gases.
• Do not reconstruct or change the settings of the protection devices.
- If the pressure switch, thermal switch, or other protection device is shorted
or operated forcibly, or parts other than those specified by Mitsubishi
Electric are used, fire or explosion may result.
• To dispose of this product, consult your dealer.
• The installer and system specialist shall secure safety against leakage
according to local regulation or standards.
- Choose the appropriate wire size and the switch capacities for the main
power supply described in this manual if local regulations are not available.
• Pay special attention to the place of installation, such as basement, etc.
where refrigeration gas can accumulate, since refrigerant is heavier than
the air.
• Children should be supervised to ensure that they do not play with the
appliance.
