• 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.

• To dispose of this product, consult your dealer.

INL

• 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 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 c leaner, 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.

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 alkylbenzene (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.

PGRRUTR

• 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 recovery 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.

- 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.

- 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

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.

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,
