•
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 refriger-
ant (R22) 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 dam-
aged.
•
If the air conditioner is installed in a small room, measures must
be taken to prevent the refrigerant concentration from exceed-
ing the safety limit even 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 de-
vices.
- 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.
1.2. Before getting installed
Caution:
•
Do not install the unit where combustible gas may leak.
- If the gas leaks and accumulates around the unit, an explosion
may result.
•
Do not use the air conditioner where food, pets, plants, preci-
sion instruments, or artwork are kept.
- The quality of the food, etc. may deteriorate.
•
Do not use the air conditioner in special environments.
- Oil, steam, sulfuric smoke, etc. can significantly reduce the per-
formance of the air conditioner or damage its parts.
•
When installing the unit in a hospital, communication station,
or similar place, provide sufficient protection against noise.
- The inverter equipment, private power generator, high-frequency
medical equipment, or radio communication equipment may cause
the air conditioner to operate erroneously, or fail to operate. On the
other hand, the air conditioner may affect such equipment by creat-
ing noise that disturbs medical treatment or image broadcasting.
•
Do not install the unit on a structure that may cause leakage.
- When the room humidity exceeds 80% or when the drain pipe is
clogged, condensation may drip from the indoor unit. Perform col-
lective drainage work together with the outdoor unit, as required.

And at servicing, please shut down the power supply for both
of Indoor Unit and Outdoor Unit.
Warning:
Carefully read the labels affixed to the main unit.
Warning:
•
Ask the dealer or an authorized technician to install the air con-
ditioner.
- Improper installation by the user may result in water leakage, elec-
tric shock, or fire.
•
Install the air unit at a place that can withstand its weight.
- Inadequate strength may cause the unit to fall down, resulting in
injuries.
•
Use the specified cables for wiring. Make the connections se-
curely 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 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 in-
jury.
•
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.
