- Inadequate connection and fastening may generate heat and

cause a fire.

Prepare for typhoons and other strong winds and earthquakes
and install the unit at the specified place.
- Improper installation may cause the unit to topple and result in

injury.

Always use an air cleaner, humidifier, electric heater, and other
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 heat exchanger fins.
- 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 instructions given in this manual and al-
ways use a special circuit.
- If the power source capacity is inadequate or electric work is per-

formed improperly, electric shock and fire may result.

Securely install the cover of control box and the panel.
- If the cover and panel are 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 the it with a refrigerant different from the refrig-
erant (
- If a different refrigerant or air is mixed with the original refrigerant,

the refrigerant cycle may malfunction and the unit may be dam-
aged.

If the air conditioner is installed in a small room, measures
must be taken to prevent the refrigerant concentration from
exceeding the safety limit even if the refrigerant should leak.
- Consult the dealer regarding the appropriate measures to pre-

vent 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, elec-

tric 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 and operated forcibly, or parts other than those specified
by Mitsubishi Electric are used, fire or explosion may result.
