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 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
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.
The installer and system specialist shall secure safety against leakage
according to local regulation or standards.
- Following standards may be applicable if local regulation 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.
With Freshair intake type, 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.
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.
•
•
•
•
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.

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.
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.
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 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 five minutes before turning off the power. Otherwise,
water leakage and trouble may occur.
Do not touch the surface of the compressor during servicing.
- If unit is connected to the supply and not running, crank case heater at compressor base is operating.

The reverse phase of L lines (L1, L2, L3) can detected (Error cord: 4103),
but the reverse phase of L lines and N line can not be detected.
- Some electric parts may be damaged when power is supplied during miss
wiring.
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 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, 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 causing damage to furniture
and other possessions.
Be very careful about transporting the product.
- One person should not carry the product as it weighs more than 20 kg.
- 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.
- 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.

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 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.
TR
•
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 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.
SV
•
•
SL
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 Data Book for more information.

Corner is not seated.
Down piping and down wiring precautions
When down piping and down wiring are performed, be sure that foundation and
base work does not block the base through holes. When down piping is performed,
make the foundation at least 100 mm high so that the piping can pass under the
bottom of the unit.
Caution:
•
•
8.1. Caution
This unit uses refrigerant R410A. Follow the local regulations on materials and
pipe thickness when selecting pipes.
2 Commercially available piping often contains dust and other materials. Always
blow it clean with a dry inert gas.
•
•
•
3 Use care to prevent dust, water or other contaminants from entering the piping
during installation.
4 Reduce the number of bending portions as much as possible, and make bending radius as big as possible.
5 Always observe the restrictions on the refrigerant piping (such as rated length,
the difference between high/low pressures, and piping diameter). Failure to do
so can result in 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. At such a
time, always properly charge the unit. 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.
•
•
8.2. Refrigerant piping system
TR
1 Use the following materials for refrigeration piping.
• Material: Use refrigerant piping made of phosphorus deoxidized copper.
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.
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 and other trouble.
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 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.

Warning:
Always use extreme care to prevent the refrigerant gas from leaking while
using fire or flame. If the refrigerant gas comes into 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.
Warning
When installing and moving the unit, do not charge it with refrigerant other
than the refrigerant specified on the unit.
- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to malfunction and result in severe damage.
SV
City Multi R2 Series is constituted by an end branching system in which the refrigerant piping from outdoor unit is branched at BC controller and connected to each
indoor unit.
The connection method adapted is brazing connection for high pressure pipe and
low pressure pipe between outdoor unit and BC controller, and flare connection
between BC controller and indoor unit. Brazing connection is employed for joint
pipe set and branch pipe set.

such problems.
HG
0 When connecting the refrigerant piping, make sure the ball 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.
PO
A Residues in commercially available antioxidants may have adverse effects on
the equipment. Braze only with non-oxide brazing material. The use of other
brazing material may result in compressor damage.
(Refer to item 9.2. for detailed information on pipe connections and valve operations.)
B Never perform outdoor unit piping connection work when it is raining.

9. Additional refrigerant charge
At the time of shipping, the outdoor unit is charged with the refrigerant. As this
charge does not include the amount needed for extended piping, additional charging for each refrigerant line will be required on site. In order that future servicing
may be properly provided, always keep a record of the size and length of each
refrigerant line and the amount of additional charge by writing it in the space provided on the outdoor unit.
9.2. Precautions concerning piping connection and valve operation
9.1. Calculation of additional refrigerant
charge
1 For brazing to the connecting pipe with flange, remove the connecting pipe
with flange from the ball valve, and braze it outside of the unit.
•
Calculate the amount of additional charge based on the length of the piping
extension and the size of the refrigerant line.
•
Use the table to the below as a guide to calculating the amount of additional
charging and charge the system accordingly.
•
If the calculation results in a fraction of less than 0.1 kg, round up to the next
0.1 kg. For example, if the result of the calculation was 10.62 kg, round the
result up to 10.7 kg.
•
Conduct piping connection and valve operation accurately.
•
Flange type side connecting pipe is assembled in factory before shipment.
2 During the time when removing the connecting pipe with flange, remove
the seal attached on the rear side of this sheet and paste it onto the flange
surface of the ball valve to prevent the entry of dust into the valve.
3 The refrigerant circuit is closed with a round, close-packed packing upon
shipment to prevent gas leak between flanges. As no operation can be
done under this state, be sure to replace the packing with the hollow packing attached at the piping connection.
4 At the mounting of the hollow packing, wipe off dust attached on the flange
sheet surface and the packing. Coat refrigerating machine oil (Ester oil,
ether oil or alkylbenzene [small amount]) onto both surfaces of the packing.

•
After evacuation and refrigerant charge, ensure that the handle is fully open. If
operating with the valve closed, abnormal pressure will be imparted to the
high- or low-pressure side of the refrigerant circuit, giving damage to the compressor, four-way valve, etc.
•
Determine the amount of additional refrigerant charge by using the formula,
and charge refrigerant additionally through the service port after completing
piping connection work.
•
After completing work, tighten the service port and cap securely not to generate gas leak.
•
Flare machining dimension for systems using R410A is larger than that for
systems using other types of refrigerant in order to increase the air tightness.
•
Refer to the table on the below for flare machining dimensions, and follow the
regulations set forth by the local authorities. Seal off the opening of the pipe
with a closure material (not supplied) to keep small animals from entering the
pipe if that is a concern.

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.
[Fig. 9.2.3] (P.3)
GB
K
Always remove the connecting pipe from the ball valve and braze it outside the unit.
- Brazing the connecting pipe while it is installed will heat the ball 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 ball 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.

Restriction
• If a flammable gas or air (oxygen) is used as the pressurization
gas, it may catch fire or explode.
2. Pressurization using refrigerant gas and nitrogen gas
(1) Pressurizing to a gas pressure of approximately 0.2 MPa, pressurize to the design pressure
(4.15 MPa) using nitrogen gas.
However, do not pressurize at one time. Stop during pressurization and check that the pressure does not drop.
(2) Check for gas leaks by checking the flare connection parts, brazed parts, flanges, and other
parts which may leak using an R410A compatible electric leak detector.
(3) This test may be used together the with bubble type gas leak test.
• Do not use a refrigerant other than that indicated on the unit.
• Sealing with gas from a cylinder will cause the composition of
the refrigerant in the cylinder to change.
• Use a pressure gauge, charging hose, and other parts especially
for R410A.
• An electric leak detector for R22 cannot detect leaks of R410A.
• Do not use a haloid torch. (Leaks cannot be detected.)

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.
SL
[Fig. 9.3.2] (P.4)
•
•
Use a gauge manifold, charging hose, and other parts for the refrigerant
indicated on the unit.
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.
HG
2 Evacuation
Evacuate with the ball valve of the outdoor unit closed and evacuate both the
connection piping and the indoor unit from the service port provided on the ball
valve of the outdoor unit using a vacuum pump. (Always evacuate from the
service port of both the high press pipe and the low press pipe.) After the
vacuum reaches 650 Pa [abs], continue evacuation for at least one hour or
more.
* Never perform air purging using refrigerant.

Caution:
Only use refrigerant R410A.
- The use of other refrigerant such as R22 or R407C, which contains chlorine, will
deteriorate the refrigerating machine oil or cause the compressor to malfunction.

Airtight test procedure
1. Nitrogen gas pressurization
(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, flanges,
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.
NL
I
E
Note:
If a torque wrench is not available, use the following method as a standard:
When you tighten the flare nut with a wrench, you will reach a point where
the tightening torque will abruptly increase. Turn the flare nut beyond this
point by the angle shown in the table above.

9.4. Thermal insulation of refrigerant piping
Penetrations
Be sure to give 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 to ceiling plenum.

Be sure to use specified wires to connect so that no external force is imparted to terminal connections. If connections are not fixed firmly, it may cause
heating or fire.
Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Some installation site may require attachment of an earth leakage breaker. If no earth leakage breaker is installed, it may cause an electric shock.
Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or copper wire with too large capacity may cause a malfunction
of unit or fire.
