• 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 always use a special circuit.

- If the power source capacity is inadequate or electric work is performed im-

properly, electric shock and fire may result.

• Securely install the outdoor unit terminal cover (panel).

- If the terminal cover (panel) 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 the it with a refrigerant different from the refrigerant (R407C or
R22) specified on the unit.

- If a different refrigerant or air is mixed with the original refrigerant, the refrig-

erant 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
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 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.

1.2. Precautions for devices that use R407C

refrigerant

Caution:

• Do not use the existing refrigerant piping.

- The old refrigerant and refrigerator oil in the existing piping contains a large

amount of chlorine which may cause the refrigerator oil of the new unit to
deteriorate.

• Use refrigerant piping made of C1220 (CU-DHP) phosphorus deoxidized
copper as specified in the JIS H3300 “Copper and copper allo y seamless
pipes and tubes”. In addition, be sure that the inner and outer surfaces of
the pipes are clean and free of hazardous sulphur , o xides, dust/dirt, shav­ing particles, oils, moisture, or any other contaminant.

- Contaminants on the inside of the refrigerant piping may cause the refriger-

ant residual oil to deteriorate.

• Store the piping to be used during installation indoors and keep both
ends of the piping sealed until just before brazing. (Store elbows and
other joints in a plastic bag.)

- If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and

compressor trouble may result.

• Use ester oil, ether oil or alkylbenz ene (small amount) as the refrigerator
oil to coat flares and flange connections.

- The refrigerator oil will degrade if it is mixed with a large amount of mineral

oil.

• Use liquid refrigerant to fill the system.

- If gas refrigerant is used to seal the system, the composition of the refriger-

ant in the cylinder will change and performance may drop.

• Do not use a refrigerant other than R407C.

- If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may
cause the refrigerator oil to deteriorate.

• Use a vacuum pump with a reverse flow check valve.

- The vacuum pump oil may flow back into the refrigerant cycle and cause the
refrigerator oil to deteriorate.

• Do not use the following tools that are used with conventional refriger­ants.
(Gauge manifold, charge hose, gas leak detector , reverse flow chec k valve,
refrigerant charge base, vacuum gauge, refrigerant reco very equipment)

- If the conventional refrigerant and refrigerator oil are mixed in the R407C,

the refrigerant may deteriorated.

- If water is mixed in the R407C, the refrigerator oil may deteriorate.

- Since R407C does not contain any chlorine, gas leak detectors for conven-

tional refrigerants will not react to it.

• Do not use a charging cylinder.

- Using a charging cylinder may cause the refrigerant to deteriorate.

• Be especially careful when managing the tools.

- If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deterio-

rate.

1.3. Before getting installed

Caution:

• Do not install the unit where combustible gas may leak.

GB

- If the gas leaks and accumulates around the unit, an explosion may result.

• Do not use the air conditioner where food, pets, plants, precision instru­ments, or artwork are kept.

- The quality of the food, etc. may deteriorate.

• Do not use the air conditioner in special environments.

D

- Oil, steam, sulfuric smoke, etc. can significantly reduce the performance 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

F

E

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 creating 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. P erform collective drainage w ork
together with the outdoor unit, as required.

• The indoor models should be installed the ceiling over than 2.5 m from
floor.

INL

1.4. Before getting installed (moved) - elec-

trical work

Caution:

• Ground the unit.

- Do not connect the ground wire to gas or water pipes, lightning rods, or

telephone ground lines. Improper grounding may result in electric shock.

• Install the power cable so that tension is not applied to the cable.

- Tension may cause the cable to break and generate heat and cause a fire.

• Install an leak circuit breaker, as required.

- If an leak circuit breaker is not installed, electric shock may result.

• Use power line cables of sufficient current carrying capacity and rating.

- Cables that are too small may leak, generate heat, and cause a fire.

• Use only a circuit breaker and fuse of the specified capacity.

- A fuse or circuit breaker of a larger capacity or a steel or copper wire may
result in a general unit failure or fire.

• Do not wash the air conditioner units.

- Washing them may cause an electric shock.

• Be careful that the installation base is not damaged by long use.

- If the damage is left uncorrected, the unit may fall and cause personal injury
or property damage.

• Install the drain piping according to this Installation Manual to ensure
proper drainage. Wrap thermal insulation around the pipes to prevent
condensation.

- Improper drain piping may cause water leakage and damage to furniture

and other possessions.

• Be very careful about product transportation.

- Only one person should not carry the product if it weighs more than 20 kg.

- Some products use PP bands for packaging. Do not use an y PP bands f or a

means of transportation. It is dangerous.

- Do not touch the heat exchanger fins. Doing so may cut your fingers.

- When transporting the outdoor unit, suspend it at the specified positions on

the unit base. Also support the outdoor unit at four points so that it cannot
slip sideways.

• Safely dispose of the packing materials.

- Packing materials, such as nails and other metal or wooden parts, may cause

stabs or other injuries.

- Tear apart and throw away plastic packaging bags so that children will not

play with them. If children play with a plastic bag which was not torn apart,
they face the risk of suffocation.

1.5. Before starting the test run

Caution:

• Turn on the power at least 12 hours before starting operation.

- Starting operation immediately after turning on the main power switch can

result in severe damage to internal parts. Keep the power switch turned on
during the operational season.

• Do not touch the switches with wet fingers.

- Touching a switch with wet fingers can cause electric shock.

• Do not touch the refrigerant pipes during and immediately after opera­tion.

- During and immediately after operation, the refrigerant pipes are may be hot

and may be cold, depending on the condition of the refrigerant flowing through
the refrigerant piping, compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the refrigerant pipes.

• Do not operate the air conditioner with the panels and guards removed.

- Rotating, hot, or high-voltage parts can cause injuries.

• Do not turn off the power immediately after stopping operation.

- Always wait at least five minutes before turning off the power. Otherwise,

water leakage and trouble may occur.
