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 dedicated power supply.
- If the power source capacity is inadequate or electric work is performed improperly, 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 it with a refrigerant different from the refrigerant 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 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
or 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.
The installer and system specialist shall secure safety against leakage
according to local regulation or standards.
- The size of the wire and capacities of the switch for the main power supply
are applicable if local regulations are not available.
Pay special attention to the place of installation, such as a basement,
etc. where refrigeration gas can accumulate, since refrigeration is heavier
than the air.
For outdoor units that allow fresh air intake to the indoor unit, the
installation site must be carefully chosen because outdoor air can directly
blow into the room when the thermostat is turned off.
- Direct exposure to outdoor air may have harmful effects on people or food.
1.2. Precautions for devices that use R410A
refrigerant
Caution:
•
Do not use 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.
- R410A is a high-pressure refrigerant and can cause the existing piping to
burst.
•
•
•
•
1.3. Before installation
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.
- 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. Perform collective drainage work
together with the outdoor unit, as required.
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 irreversible damage to internal parts. Keep the power switch turned
on during the operational season. Make sure of the phase order of power
supply and voltage between each phase.
Do not touch the switches with wet fingers.
- Touching a switch with wet fingers can result in an electric shock.
Do not touch the refrigerant pipes during and immediately after operation.
- During and immediately after operation, the refrigerant pipes may be hot or
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 5 minutes before turning off the power. Otherwise,
drainage water leakage or mechanical failure of sensitive parts may occur.
Do not touch the surface of the compressor during servicing.
- If unit is connected to a supply and not running, the crank case heater located
at the base of the compressor may still be operating.
Some of the tools and equipment used for installation with systems that use
other types of refrigerant cannot be used with the systems using R410A. Refer
to the Data Book for more information.
•
Do not use the existing piping, as it contains chlorine, which is found in conventional refrigerating machine oil and refrigerant. This chlorine will deteriorate
the refrigerant machine oil in the new equipment. The existing piping must not
be used as the design pressure in systems using R410A is higher than that in
the systems using other types of refrigerant and the existing pipes may burst.
GB
SL
•
HG
Piping for systems using R410A may be different from that for systems using
conventional refrigerant because the design pressure in systems using R410A
is higher. Refer to the Data Book for more information.

- Tension may cause the cable to break and generate heat and cause a fire.
Install a leak circuit breaker, as required.
- If a 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 the use of a substitute simple
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 causing damage to furniture
and other possessions.
Be very careful about transporting the product.
- One person should not carry the product. Its weight is in excess of 20kg.
- Some products use PP bands for packaging. Do not use any PP bands as 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, support 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.

1.4. Before installation (relocation) - electrical work
TR
•
Use refrigerant piping made of phosphorus deoxidized 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 failure may result.
Apply a small amount of ester oil, ether oil, or alkyl benzene to flares. (for
indoor unit)
- Infiltration of a large amount of mineral oil may cause the refrigerator oil to
deteriorate.
Use liquid refrigerant to fill the system.
- If gas refrigerant is used to fill the system, the composition of the refrigerant
in the cylinder will change and performance may drop.
Do not use a refrigerant other than R410A.
- If another refrigerant (R22, etc.) is mixed with R410A, 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 R410A,
the refrigerant may deteriorated.
- If water is mixed in the R410A, the refrigerator oil may deteriorate.
- Since R410A does not contain any chlorine, gas leak detectors for 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 into the refrigerant cycle, the refrigerant may deteriorate.

height difference, and piping diameter) to prevent equipment failure or a decline in heating/cooling performance.
6 Either a lack or an excess of refrigerant causes the unit to make an emergency
stop. Charge the system with an appropriate amount of refrigerant. When servicing, always check the notes concerning pipe length and amount of additional
refrigerant at both locations, the refrigerant volume calculation table on the
back of the service panel and the additional refrigerant section on the labels
for the combined number of indoor units (Refer to item 8.2. for detailed information on refrigerant piping system).
•
•
Use a vacuum pump with a reverse flow check valve.
- If the vacuum pump does not have a reverse flow check valve, the vacuum
pump oil may flow back into the refrigerant cycle and cause deterioration of
the refrigerator oil.
Do not use the tools shown below used with conventional refrigerant.
(Gauge manifold, charge hose, gas leak detector, check valve, refrigerant
charge base, vacuum gauge, refrigerant recovery equipment)
- Mixing of conventional refrigerant and refrigerator oil may cause the refrigerator oil to deteriorate.
- Mixing of water will cause the refrigerator oil to deteriorate.
- R410A refrigerant does not contain any chlorine. Therefore, gas leak detectors for conventional refrigerants will not react to it.
Manage the tools used for R410A more carefully than normal.
- If dust, dirt, or water gets in the refrigerant cycle, the refrigerator oil will deteriorate.
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 deteriorate and
the compressor may fail.
Do not use a charging cylinder.
- Using a charging cylinder may cause the refrigerant to deteriorate.
Do not use special detergents for washing piping.

1 Use the following materials for refrigeration piping.
• Material: Use copper alloy seamless pipes made of phosphorus deoxidized copper. Ensure the inner and outer surfaces of the pipes are clean
and free from hazardous sulfur, oxide, dusts, shaving particles, oils, and
moisture (contamination).
• Size: Refer to item 8.2. for detailed information on refrigerant piping system.
NL
This unit uses refrigerant R410A. Follow the local regulations on materials and
pipe thickness when selecting pipes. (Refer to the table below.)
A Braze only with non-oxide brazing material for piping. Failure to do so
may damage the compressor. Be sure to perform the non-oxidation brazing with a nitrogen purge.
Do not use any commercially available anti-oxidizing agent since it may
cause pipe corrosion and degrading of the refrigerant oil.
Please contact Mitsubishi Electric for more details.
(Refer to item 9.2. for details of the piping connection and valve operation)
P
8.1. Caution
0 When connecting the refrigerant piping, make sure the valve of the outdoor
unit is completely closed (the factory setting) and do not operate it until the
refrigerant piping for the outdoor and indoor units has been connected, a refrigerant leakage test has been performed and the evacuation process has
been completed.
GR
Always use extreme care to prevent the refrigerant gas from leaking while
using fire or flame. If the refrigerant gas comes in to contact with a flame
from any source, such as a gas stove, it breaks down and generates a poisonous gas which can cause gas poisoning. Never weld in an unventilated
room. Always conduct an inspection for gas leakage after installation of the
refrigerant piping has been completed.
9 Always insulate the piping properly. Insufficient insulation will result in a decline in heating/cooling performance, water drops from condensation and other
such problems (Refer to item 9.4 for thermal insulation of refrigerant piping).
RU
Warning:
8 Never use refrigerant to perform an air purge. Always evacuate using a
vacuum pump.
TR
The pipe is connected via a terminal-branch type connection in which refrigerant
piping from the outdoor unit is branched at the terminal and is connected to each
of the indoor units.
The method of pipe connection is as follows: flare connection for the indoor units,
gas pipes for outdoor units, brazed connection; liquid pipes, flare connection. Note
that the branched sections are brazed.

When connecting a pipe to the service valve, be sure to use only the supplied
open-end flare nut, with small holes cut into the flats.
* Using a regular flare nut (i.e., non-supplied) will result in any water that naturally flows into the nut being unable to escape.
Consequently, when the temperature becomes low, this water inside the nut
may freeze and cause damage to the joint. This, in turn, may result in a gas
leakage.

Always remove the connecting pipe from the valve and braze it outside
the unit.
- Brazing the connecting pipe while it is installed will heat the valve and cause
trouble or gas leakage. The piping, etc. inside the unit may also be burned.
Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerating machine oil to coat flares and flange connections.
- The refrigerating machine oil will degrade if it is mixed with a large amount of
mineral oil.
Keep the valve closed until refrigerant charging to the pipes to be added
on site has been completed. Opening the valve before charging the refrigerant may result in unit damage.
Do not use a leak detection additive.

Observe the following restrictions when conducting an air tightness test to prevent
negative effects on the refrigerating machine oil. Also, with nonazeotropic refrigerant (R410A), gas leakage causes the composition to change and affects performance. Therefore, perform the airtightness test cautiously.
Airtight test procedure
Restriction
• If a flammable gas or air (oxygen) is used as the pressurization
gas, it may catch fire or explode.
GB
(1) After pressurizing to the design pressure (4.15 MPa) using nitrogen gas, allow it to stand for
about one day. If the pressure does not drop, airtightness is good.
However, if the pressure drops, since the leaking point is unknown, the following bubble test
may also be performed.
(2) After the pressurization described above, spray the flare connection parts, brazed parts, and
other parts that may leak with a bubbling agent (Kyuboflex, etc.) and visually check for bubbles.
(3) After the airtight test, wipe off the bubbling agent.

2 Evacuation
Evacuate with the valve of the outdoor unit closed and evacuate both the connection piping and the indoor unit from the service port provided on the valve
of the outdoor unit using a vacuum pump. (Always evacuate from the service
port of both liquid pipe and gas pipe.) After the vacuum reaches 650 Pa [abs],
continue evacuation for at least one hour or more. Then, stop the vacuum
pump and leave it for 1 hour. Ensure the degree of vacuum has not increased.
(If the degree of vacuum increase is larger than 130 Pa, water might have
entered. Apply pressure to dry nitrogen gas up to 0.05 MPa and vacuum
again.) Finally, seal in with the liquid refrigerant through the liquid pipe, and
adjust the gas piping to obtain an appropriate amount of the refrigerant during
operation.
* Never perform air purging using refrigerant.
Be sure to add insulation work to refrigerant piping by covering liquid pipe and gas
pipe separately with enough thickness heat-resistant polyethylene, so that no gap
is observed in the joint between indoor unit and insulating material, and insulating
materials themselves. When insulation work is insufficient, there is a possibility of
condensation drip, etc. Pay special attention to insulation work in the ceiling plenum.
D
9.4. Thermal insulation of refrigerant piping
Caution:
Only use refrigerant R410A.
- The use of other refrigerants such as R22 or R407C, which contains chlorine,
will deteriorate the refrigerating machine oil or cause the compressor to malfunction.

• Use a graviometer. (One that can measure down to 0.1 kg.)
• Use a vacuum pump with a reverse flow check valve.
(Recommended vacuum gauge: ROBINAIR 14830A Thermistor Vacuum
Gauge)
Also use a vacuum gauge that reaches 65 Pa [abs] or below after operating for five minutes.
3 Refrigerant Charging
Since the refrigerant used with the unit is nonazerotropic, it must be charged in
the liquid state. Consequently, when charging the unit with refrigerant from a
cylinder, if the cylinder does not have a syphon pipe, charge the liquid refrigerant by turning the cylinder upside-down as shown in Fig. 9.3.3. If the cylinder
has a syphon pipe like that shown in the picture on the right, the liquid refrigerant can be charged with the cylinder standing upright. Therefore, give careful
attention to the cylinder specifications. If the unit should be charged with gas
refrigerant, replace all the refrigerant with new refrigerant. Do not use the refrigerant remaining in the cylinder.
