a fire.
• Prepare for earthquakes and install the unit at the specified place.
- Improper installation may cause the unit to result in injury.
• Always use 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.
• 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 always 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.
- 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 refrigerant (R407C or 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 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, w ater 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 con-
tains 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 alloy seamless pipes and tubes”. In addition, be sure
that the inner and outer surfaces of the pipes are clean and free
of hazardous sulphur, oxides, dust/dirt, shaving particles, oils,
moisture, or any other contaminant.
- Contaminants on the inside of the refrigerant piping may cause the
refrigerant 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.
ENGLISH
3
• 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
refrigerant 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
check valve, refrigerant charge base, 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
ENGLISH
conventional 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 deteriorate.
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 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 f ail 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 or BC controller. P erform collective drainage w ork together with the outdoor unit,
as required.
• 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 any PP
bands for a means of transportation. It is dangerous.
- Do not touch the heat exchanger fins. Doing so may cut your fin-
gers.
- When transporting the outdoor unit, suspend it at the specified po-
sitions 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.
- T ear apart and throw aw ay 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 min utes before turning off the power. Oth-
erwise, water leakage and trouble may occur.
1.4. Before getting installed (moved) electrical 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.
- T ension 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.

4.1. Connecting refrigerant pipes
1. Connect the liquid and gas pipes of each indoor unit to the same end
connection numbers as indicated on the indoor unit flare connection
section of each BC controller. If connected to wrong end connection
numbers, there will be no normal operation.
2. List indoor unit model names in the name plate on the BC controller
control box (for identification purposes), and BC controller end connection numbers and address numbers in the name plate on the
indoor unit side.
3. If the number of connected indoor units is less than the number of
branch holes, it does not matter which end connections you leave.
Seal unused end connections using flare nuts with end caps just as
they were capped when shipped from the factory . No end cap means
refrigerant leakage.
4. When using branch pipes (CMY-Y102S-F), be sure to connect them
at level.
5. Be sure to tighten the flare nuts using a double spanner. Otherwise
ENGLISH
the refrigerant may leak.
6. Be sure to use non-oxidative brazing where necessary. If you do not
use non-oxidative brazing, it may clog the pipes.
7. After completing pipe connection, support the pipes to prevent that
load is imparted to the BC controller’s end connections (particularly
to the gas pipes of indoor units).
Warning :
When installing and moving the unit, do not charge it with refrigerant other than the refrigerant (R407C or R22) specified on the unit.
- Mixing of a different refrigerant, air, etc. may cause the refrigerant cy-
cle to malfunction and result in severe damage.
Caution:
• Use refrigerant piping made of C1220 (CU-DHP) phosphorus
deoxidized copper as specified in the JIS H3300 “Copper and
copper alloy seamless pipes and tubes”. In addition, be sure
that the inner and outer surfaces of the pipes are clean and free
of hazardous sulphur, oxides, dust/dirt, shaving particles, oils,
moisture, or any other contaminant.
• Never use existing refrigerant piping.
- The large amount of chlorine in conventional refrigerant and refrigerator oil in the existing piping will cause the new refrigerant to
deteriorate.
• Store the piping to be used during installation indoors and keep
both ends of the piping sealed until just before brazing.
- If dust, dirt, or water gets into the refrigerant cycle, the oil will dete-
riorate and the compressor may fail.
• Use Suniso 4GS or 3GS (small amount) refrigerator oil to coat
the flare and flange connection part. (For models using R22)
• Use ester oil, ether oil or alkylbenzene (small amount) as the
refrigerator oil to coat flares and flange connections. (For models using R407C)
- The refrigerant used in the unit is highly hygroscopic and mixes
with water and will degrade the refrigerator oil.
