1. Safety precautions
After installation work has been completed, explain the
“Safety Precautions,” use, and maintenance of the unit to
the customer according to the information in the Operation
Manual and perform the test run to ensure normal opera-
tion. Both the Installation Manual and Operation Manual
must be given to the user for keeping. These manuals
must be passed on to subsequent users.
: Indicates a part which must be grounded.
Warning:
Carefully read the labels afxed to the main unit.
Warning:
• The unit must not be installed by the user. Ask a
dealer or an authorized technician to install the unit.
If the unit is installed incorrectly, water leakage,
electric shock, or re may result.
• For installation work, follow the instructions in the
Installation Manual and use tools and pipe compo-
nents specically made for use with R410A refrig-
erant. The R410A refrigerant in the HFC system is
pressurized 1.6 times the pressure of usual refrig-
erants. If pipe components not designed for R410A
refrigerant are used and the unit is not installed cor-
rectly, the pipes may burst and cause damage or
injuries. In addition, water leakage, electric shock,
or re may result.
•When installing the unit, use appropriate protec-
tive equipment and tools for safety. Failure to do so
could cause injuries.
• The unit must be installed according to the instruc-
tions in order to minimize the risk of damage from
earthquakes, typhoons, or strong winds. An incor-
rectly installed unit may fall down and cause dam-
age or injuries.
• The unit must be securely installed on a structure
that can sustain its weight. If the unit is mounted on
an unstable structure, it may fall down and cause
damage or injuries.
• If the outdoor unit is installed in a small room,
measures must be taken to prevent the refriger-
ant concentration in the room from exceeding the
safety limit in the event of refrigerant leakage. Con-
sult a dealer regarding the appropriate measures
to prevent the allowable concentration from being
exceeded. Should the refrigerant leak and cause the
concentration limit to be exceeded, hazards due to
lack of oxygen in the room may result.
• Ventilate the room if refrigerant leaks during opera-
tion. If refrigerant comes into contact with a ame,
poisonous gases will be released.

• All electric work must be performed by a qualied
technician according to local regulations and the
instructions given in this manual. The units must be
powered by dedicated power lines and the correct
voltage and circuit breakers must be used. Power
lines with insufcient capacity or incorrect electri-
cal work may result in electric shock or re.
• Use C1220 copper phosphorus, for copper and cop-
per alloy seamless pipes, to connect the refriger-
ant pipes. If the pipes are not connected correctly,
the unit will not be properly grounded and electric
shock may result.
• Use only specied cables for wiring. The wiring
connections must be made securely with no ten-
sion applied on the terminal connections. Also,
never splice the cables for wiring (unless otherwise
indicated in this document).
Failure to observe these instructions may result in
overheating or a re.
• The terminal block cover panel of the outdoor unit
must be rmly attached. If the cover panel is mount-
ed incorrectly and dust and moisture enter the unit,
electric shock or re may result.
•When installing or relocating, or servicing the out-
door unit, use only the specied refrigerant (R410A)
to charge the refrigerant lines. Do not mix it with any
other refrigerant and do not allow air to remain in
the lines.
If air is mixed with the refrigerant, then it can be the
cause of abnormal high pressure in the refrigerant
line, and may result in an explosion and other haz-
ards.
The use of any refrigerant other than that speci-
ed for the system will cause mechanical failure or
system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to se-
curing product safety.
• Use only accessories authorized by Mitsubishi
Electric and ask a dealer or an authorized techni-
cian to install them. If accessories are incorrectly
installed, water leakage, electric shock, or re may
result.
•Do not alter the unit. Consult a dealer for repairs. If
alterations or repairs are not performed correctly,
water leakage, electric shock, or re may result.
• The user should never attempt to repair the unit or
transfer it to another location. If the unit is installed
incorrectly, water leakage, electric shock, or re
may result. If the outdoor unit must be repaired or
moved, ask a dealer or an authorized technician.
• After installation has been completed, check for
refrigerant leaks. If refrigerant leaks into the room
and comes into contact with the ame of a heater
or portable cooking range, poisonous gases will be
released.
•When opening or closing the valve below freezing
temperatures, refrigerant may spurt out from the
gap between the valve stem and the valve body, re-
sulting in injuries.

1.1. Before installation
Caution:
• Do not use the unit in an unusual environment. If the
outdoor unit is installed in areas exposed to steam,
volatile oil (including machine oil), or sulfuric gas,
areas exposed to high salt content such as the
seaside, or areas where the unit will be covered by
snow, the performance can be signicantly reduced
and the internal parts can be damaged.
• Do not install the unit where combustible gases
may leak, be produced, ow, or accumulate. If com-
bustible gas accumulates around the unit, re or
explosion may result.
•The outdoor unit produces condensation during
the heating operation. Make sure to provide drain-
age around the outdoor unit if such condensation is
likely to cause damage.
• Remove the compressor’s xing component in ac-
cordance with the NOTICE attached to the unit. Run-
ning the unit with the xing component mounted
will result in increased noise.
• When installing the unit in a hospital or communi-
cations ofce, be prepared for noise and electronic
interference. Inverters, home appliances, high-
frequency medical equipment, and radio commu-
nications equipment can cause the outdoor unit to
malfunction or breakdown. The outdoor unit may
also affect medical equipment, disturbing medical
care, and communications equipment, harming the
screen display quality.
•When the unit is running, vibrations or the noise of
refrigerant running may be heard from the exten-
sion piping. Try to avoid installing the piping to thin
walls, etc. as much as possible and provide sound
insulation with the piping cover, etc.
1. Safety precautions
1.2. Before installation (relocation)
Caution:
• Be extremely careful when transporting or install-
ing the units. Two or more persons are needed to
handle the unit, as it weighs 20 kg or more. Do not
grasp the packaging bands. Wear protective gloves
to remove the unit from the packaging and to move
it, as you can injure your hands on the ns or the
edge of other parts.
• Be sure to safely dispose of the packaging mate-
rials. Packaging materials, such as nails and other
metal or wooden parts may cause stabs or other in-
juries.
1.3. Before electric work
Caution:
• Be sure to install circuit breakers. If not installed,
electric shock may result.
• For the power lines, use standard cables of suf-
cient capacity. Otherwise, a short circuit, overheat-
ing, or re may result.
•When installing the power lines, do not apply ten-
sion to the cables. If the connections are loosened,
the cables can snap or break and overheating or re
may result.
• The base and attachments of the outdoor unit must
be periodically checked for looseness, cracks or
other damage. If such defects are left uncorrected,
the unit may fall down and cause damage or inju-
ries.
• Do not clean the outdoor unit with water. Electric
shock may result.
• Tighten all are nuts to specication using a torque
wrench. If tightened too much, the are nut can
break after an extended period and refrigerant can
leak out.
•Be sure to ground the unit. Do not connect the
ground wire to gas or water pipes, lightning rods, or
telephone grounding lines. If the unit is not properly
grounded, electric shock may result.
• Use circuit breakers (ground fault interrupter, iso-
lating switch (+B fuse), and molded case circuit
breaker) with the specied capacity. If the circuit
breaker capacity is larger than the specied capac-
ity, breakdown or re may result.

1. Safety precautions
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours
before starting operation. Starting operation just
after turning on the power switch can severely dam-
age the internal parts. Keep the main power switch
turned on during the operation season.
• Before starting operation, check that all panels,
guards and other protective parts are correctly
installed. Rotating, hot, or high voltage parts can
cause injuries.
• Do not touch any switch with wet hands. Electric
shock may result.
•Do not touch the refrigerant pipes with bare hands
during operation. The refrigerant pipes are hot or
cold depending on the condition of the owing re-
frigerant. If you touch the pipes, burns or frostbite
may result.
• After stopping operation, be sure to wait at least ve
minutes before turning off the main power switch.
Otherwise, water leakage or breakdown may result.
1.5. Using R410A refrigerant outdoor units
Caution:
• Use C1220 copper phosphorus, for copper and cop-
per alloy seamless pipes, to connect the refrigerant
pipes. Make sure the insides of the pipes are clean
and do not contain any harmful contaminants such
as sulfuric compounds, oxidants, debris, or dust.
Use pipes with the specied thickness. (Refer to
5.1.) Note the following if reusing existing pipes that
carried R22 refrigerant.
- Replace the existing are nuts and are the ared sec-
tions again.
- Do not use thin pipes. (Refer to 5.1.)
•Store the pipes to be used during installation in-
doors and keep both ends of the pipes sealed until
just before brazing. (Leave elbow joints, etc. in their
packaging.) If dust, debris, or moisture enters the
refrigerant lines, oil deterioration or compressor
breakdown may result.
• Use ester oil, ether oil, alkylbenzene oil (small
amount) as the refrigeration oil applied to the ared
sections. If mineral oil is mixed in the refrigeration
oil, oil deterioration may result.
• Do not use refrigerant other than R410A refrigerant.
If another refrigerant is used, the chlorine will cause
the oil to deteriorate.
• Use the following tools specically designed for
use with R410A refrigerant. The following tools are
necessary to use R410A refrigerant. Contact your
nearest dealer for any questions.
Tools (for R410A)
Gauge manifold Flare tool
Charge hose Size adjustment gauge
Gas leak detector Vacuum pump adapter
Torque wrench Electronic refrigerant charg-
ing scale
•Be sure to use the correct tools. If dust, debris, or
moisture enters the refrigerant lines, refrigeration
oil deterioration may result.
•Do not use a charging cylinder. If a charging cylin-
der is used, the composition of the refrigerant will
change and the efciency will be lowered.

2.2. Choosing the outdoor unit installation location
•Avoid locations exposed to direct sunlight or other sources of heat.
•Select a location from which noise emitted by the unit will not inconvenience
neighbors.
•Select a location permitting easy wiring and pipe access to the power source and
indoor unit.
• Avoid locations where combustible gases may leak, be produced, ow, or ac-
cumulate.
•Note that water may drain from the unit during operation.
•Select a level location that can bear the weight and vibration of the unit.
•Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation loca-
tion or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the airow
and a malfunction may result.
•Avoid locations exposed to oil, steam, or sulfuric gas.
•Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or ngers may be pinched.

5. Installing the refrigerant piping
5.1. Precautions for devices that use R410A refrigerant
If air is mixed with the refrigerant, then it can be the
cause of abnormal high pressure in the refrigerant
line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specied
for the system will cause mechanical failure or sys-
tem malfunction or unit breakdown. In the worst case,
this could lead to a serious impediment to securing
product safety.

• Do not use pipes thinner than those specied
above.
• Use 1/2 H or H pipes if the diameter is 22.2 mm or
larger.
• Refer to 1.5. for precautions not included below on
using outdoor units with R410A refrigerant.
• Use ester oil, ether oil, alkylbenzene oil (small
amount) as the refrigeration oil applied to the ared
sections.
• Use C1220 copper phosphorus, for copper and cop-
per alloy seamless pipes, to connect the refrigerant
pipes. Use refrigerant pipes with the thicknesses
specied in the table to the below. Make sure the in-
sides of the pipes are clean and do not contain any
harmful contaminants such as sulfuric compounds,
oxidants, debris, or dust.
Always apply no-oxidation brazing when brazing
the pipes, otherwise, the compressor will be dam-
aged.
Warning:
When installing or relocating, or servicing the out-
door unit, use only the specied refrigerant (R410A)
to charge the refrigerant lines. Do not mix it with any
other refrigerant and do not allow air to remain in the
lines.
• After removing the COMP xed parts, be sure to tighten nuts, and make COMP
CASE TOP and COMP CASE FRONT back to the original state. (Fig. 4-2)

5. Installing the refrigerant piping
5.2. Connecting pipes (Fig. 5-1)
• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100 °C or
more, thickness of 12 mm or more). Direct contact with the bare piping may result
in burns on frostbite.
•The indoor parts of the drain pipe should be wrapped with polyethylene foam
insulation materials (specic gravity of 0.03, thickness of 9 mm or more).
•Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening
are nut. A
• Apply refrigerating machine oil over the entire are seat surface. B
• Use the are nuts for the following pipe size. C
• For connection, rst align the center, then tighten the rst 3 to 4 turns of are nut
by hand.
• Use 2 wrenches to tighten piping connections. D
•Use leak detector or soapy water to check for gas leaks after connections are
completed.

• When bending the pipes, be careful not to break them. Bend radii of 100 mm to
150 mm are sufcient.
•Make sure the pipes do not contact the compressor. Abnormal noise or vibration
may result.
1Pipes must be connected starting from the indoor unit.
Flare nuts must be tightened with a torque wrench.
2 Flare the liquid pipes and gas pipes and apply a thin layer of refrigeration oil (Ap-
plied on site).
• When usual pipe sealing is used, refer to Table 1 for aring of R410A refrigerant
pipes.

Remove the service panel D (4 screws) and the front piping cover A (2 screws) and
rear piping cover B (4 screws).
1Perform refrigerant piping connections for the indoor/outdoor unit when the out-
door unit’s stop valve is completely closed.
2Vacuum-purge air from the indoor unit and the connection piping.
3After connecting the refrigerant pipes, check the connected pipes and the indoor
unit for gas leaks. (Refer to 5.4 Refrigerant pipe airtight testing method)
4A high-performance vacuum pump is used at the stop valve service port to main-
tain a vacuum for an adequate time (at least one hour after reaching –101 kPa (5
Torr)) in order to vacuum dry the inside of the pipes. Always check the degree of
vacuum at the gauge manifold. If there is any moisture left in the pipe, the degree
of vacuum is sometimes not reached with short-time vacuum application.
After vacuum drying, completely open the stop valves (both liquid and gas) for the
outdoor unit. This completely links the indoor and outdoor refrigerant circuits.
•
If the vacuum drying is inadequate, air and water vapor remain in the refrigerant
circuits and can cause abnormal rise of high pressure, abnormal drop of low
pressure, deterioration of the refrigerating machine oil due to moisture, etc.
• If the stop valves are left closed and the unit is operated, the compressor and
control valves will be damaged.
• Use a leak detector or soapy water to check for gas leaks at the pipe connec-
tion sections of the outdoor unit.
• Do not use the refrigerant from the unit to purge air from the refrigerant lines.
• After the valve work is completed, tighten the valve caps to the correct torque:
20 to 25 N·m (200 to 250 kgf·cm).
Failure to replace and tighten the caps may result in refrigerant leakage. In
addition, do not damage the insides of the valve caps as they act as a seal to
prevent refrigerant leakage.
5Use sealant to seal the ends of the thermal insulation around the pipe connection
sections to prevent water from entering the thermal insulation.
Warning:
When installing the unit, securely connect the refriger-
ant pipes before starting the compressor.

5.4. Refrigerant pipe airtight testing method (Fig. 5-4)
(1) Connect the testing tools.
• Make sure the stop valves ABare closed and do not open them.
• Add pressure to the refrigerant lines through the service port Cof the liquid
stop valve A.
(2) Do not add pressure to the specied pressure all at once; add pressure little by
little.
1 Pressurize to 0.5 MPa (5 kgf/cm2G), wait ve minutes, and make sure the
pressure does not decrease.
2 Pressurize to 1.5 MPa (15 kgf/cm2G), wait ve minutes, and make sure the
pressure does not decrease.
3 Pressurize to 4.15 MPa (41.5 kgf/cm2G) and measure the surrounding tem-
perature and refrigerant pressure.
(3) If the specied pressure holds for about one day and does not decrease, the
pipes have passed the test and there are no leaks.
• If the surrounding temperature changes by 1 °C, the pressure will change by
about 0.01 MPa (0.1 kgf/cm2G). Make the necessary corrections.
(4) If the pressure decreases in steps (2) or (3), there is a gas leak. Look for the
source of the gas leak.
5.5. Stop valve opening method
The stop valve opening method varies according to the outdoor unit model. Use the
appropriate method to open the stop valves.
(1) Gas side (Fig. 5-5)
1Remove the cap, pull the handle toward you and rotate 1/4 turn in a counterclock-
wise direction to open.
2Make sure that the stop valve is open completely, push in the handle and rotate
the cap back to its original position.
(2) Liquid side (Fig. 5-6)
1Remove the cap and turn the valve rod counterclockwise as far as it will go with
the use of a 4 mm hexagonal wrench. Stop turning when it hits the stopper.
(ø9.52: Approximately 10 revolutions)
2Make sure that the stop valve is open completely, push in the handle and rotate
the cap back to its original position.
Refrigerant pipes are protectively wrapped
• The pipes can be protectively wrapped up to a diameter of ø90 before or after
connecting the pipes. Cut out the knockout in the pipe cover following the groove
and wrap the pipes.
Pipe inlet gap
•Use putty or sealant to seal the pipe inlet around the pipes so that no gaps re-
main. (If the gaps are not closed, noise may be emitted or water and dust will
enter the unit and breakdown may result.)
5.6. Addition of refrigerant
• Additional charging is not necessary if the pipe length does not exceed 10 m.
• If the pipe length exceeds 10m, charge the unit with additional R410A refrigerant
according to the permitted pipe lengths in the chart below.
* When the unit is stopped, charge the unit with the additional refrigerant through
the liquid stop valve after the pipe extensions and indoor unit have been vacu-
umized.
When the unit is operating, add refrigerant to the gas check valve using a
safety charger. Do not add liquid refrigerant directly to the check valve.
* After charging the unit with refrigerant, note the added refrigerant amount on
the service label (attached to the unit).
Refer to the “1.5. Using R410A refrigerant outdoor unit” for more information.
•Be careful when installing multiple units. Connecting to an incorrect indoor unit
can lead to abnormally high pressure and have a serious effect on operation
performance.
IDouble spanner section
(Do not apply a spanner other than to this section.
Doing so would cause coolant leaks.)

Warning:
· In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit de-
sign that has no electrical insulation between power line and communication signal line. Therefore, please
turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power
is energized. If isolator should be used between indoor unit and outdoor unit, please use 3-pole type.
Notes: 1. Wiring size must comply with the applicable local and national codes.
2.
Power supply cables and the cables between Interface unit/Flow temp. controller and outdoor unit shall not be lighter than polychloroprene sheathed
exible cables. (Design 60245 IEC 57
)
3. Be sure to connect the cables between
Interface unit/Flow temp. controller and outdoor unit directly to the units (no intermediate connections are al-
lowed).
Intermediate connections may result in communication errors. If water enters at the intermediate connection point, it may cause insufcient insulation
to ground or a poor electrical contact.
(If an intermediate connection is necessary, be sure to take measures to prevent water from entering the cables.)
4. Install an earth longer than other cables.
5. Do not construct a system with a power supply that is turned ON and OFF frequently.
6. Use self-extinguishing distribution cables for power supply wiring.
7. Properly route wiring so as not to contact the sheet metal edge or a screw tip.

9.1. Before test run
► After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power supply
or control wiring, wrong polarity, and no disconnection of one phase in the
supply.
► Use a 500-volt megohmmeter to check that the resistance between the
power supply terminals and ground is at least 1 MΩ.
► Do not carry out this test on the control wiring (low voltage circuit) termi-
nals.
Warning:
Do not use the outdoor unit if the insulation resistance
is less than 1 MΩ.
Insulation resistance
After installation or after the power source to the unit has been cut for an extended
period, the insulation resistance will drop below 1 MΩ due to refrigerant accumulat-
ing in the compressor. This is not a malfunction. Perform the following procedures.
1. Remove the wires from the compressor and measure the insulation resistance of
the compressor.
2. If the insulation resistance is below 1 MΩ, the compressor is faulty or the resist-
ance dropped due the accumulation of refrigerant in the compressor.
3. After connecting the wires to the compressor, the compressor will start to warm
up after power is supplied. After supplying power for the times indicated below,
measure the insulation resistance again.
• The insulation resistance drops due to accumulation of refrigerant in the com-
pressor. The resistance will rise above 1 MΩ after the compressor is warmed
up for 4 hours.
(The time necessary to warm up the compressor varies according to atmos-
pheric conditions and refrigerant accumulation.)
• To operate the compressor with refrigerant accumulated in the compressor,
the compressor must be warmed up at least 12 hours to prevent breakdown.
4. If the insulation resistance rises above 1 MΩ, the compressor is not faulty.
Caution:
• The compressor will not operate unless the power
supply phase connection is correct.
• 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.
► The followings must be checked as well.
•The outdoor unit is not faulty. LED1 and LED2 on the control board of the outdoor
unit ash when the outdoor unit is faulty.
•Both the gas and liquid stop valves are completely open.
9. Test run
9.2. Using remote controller
Refer to the indoor unit installation manual.
Note :
Occasionally, vapor that is made by the defrost operation may seem as if smoke come up from the outdoor unit.
10.1. Refrigerant collecting (pump down)
Perform the following procedures to collect the refrigerant when moving the indoor
unit or the outdoor unit.
1 Supply power (circuit breaker).
* When power is supplied, make sure that “CENTRALLY CONTROLLED” is not
displayed on the remote controller. If “CENTRALLY CONTROLLED” is dis-
played, the refrigerant collecting (pump down) cannot be completed normally.
* Start-up of the indoor-outdoor communication takes about 3 minutes after the
power (circuit breaker) is turned on. Start the pump-down operation 3 to 4
minutes after the power (circuit breaker) is turned ON.
* In the case of multi-units control, before powering on, disconnect the wiring
between the master indoor unit and the slave indoor unit. For more details
refer to the installation manual for the indoor unit.
2 After the liquid stop valve is closed, set the SWP switch on the control board of
the outdoor unit to ON. The compressor (outdoor unit) and ventilators (indoor and
outdoor units) start operating and refrigerant collecting operation begins. LED1
and LED2 on the control board of the outdoor unit are lit.
* Only set the SWP switch (push-button type) to ON if the unit is stopped. How-
ever, even if the unit is stopped and the SWP switch is set to ON less than 3
minutes after the compressor stops, the refrigerant collecting operation cannot
be performed. Wait until compressor has been stopped for 3 minutes and then
set the SWP switch to ON again.
3Because the unit automatically stops in about 2 to 3 minutes when the refrigerant
collecting operation is completed (LED1 off, LED2 lit), be sure to quickly close
the gas stop valve. If LED1 is lit and LED2 is off and the outdoor unit is stopped,
refrigerant collection is not properly performed. Open the liquid stop valve com-
pletely, and then repeat step 2after 3 minutes have passed.
* If the refrigerant collecting operation has been completed normally (LED1 off,
LED2 lit), the unit will remain stopped until the power supply is turned off.
4 Turn off the power supply (circuit breaker).
* Note that when the extension piping is very long with large refrigerant amount,
it may not be possible to perform a pump-down operation. When performing
the pump-down operation, make sure that the low pressure is lowered to near
0 MPa (gauge).
Warning:
• When pumping down the refrigerant, stop the com-
pressor before disconnecting the refrigerant pipes.
The compressor may burst if air etc. get into it.
• Do not perform pump down work when there is a
gas leak. The intake of air or other gases causes
abnormally high pressure in the refrigeration cycle,
which may cause explosion or injury.

1. Меры предосторожности
После окончания установочных работ проинструктируй-
те пользователя относительно правил эксплуатации и
обслуживания аппарата, а также ознакомьте с разде-
лом “Мера предосторожности” в соответствии с инфор-
мацией, приведенной в Руководстве по использованию
аппарата, и выполните тестовый прогон аппарата для
того, чтобы убедиться, что он работает нормально.
Обязательно передайте пользователю на хранение эк-
земпляры Руководства по установке и Руководства по
эксплуатации. Эти Руководства должны быть переданы
и последующим пользователям данного прибора.
: Указывает, что данная часть должна быть зазем-
лена.
Предупреждение:
Внимательно прочтите текст на этикетках главного
прибора.
Предупреждение:
• Прибор не должен устанавливаться пользова-
телем. Для выполнения установки прибора об-
ратитесь к дилеру или сертифицированному
техническому специалисту. Неправильная уста-
новка аппарата может повлечь за собой протеч-
ку воды, удар электрическим током или возник-
новение пожара.
• При установочных работах следуйте инструкци-
ям в Руководстве по установке. Используйте ин-
струменты и детали трубопроводов, специально
предназначенные для использования с хладаген-
том марки R410A. Хладагент R410A в HFC-системе
находится под давлением в 1,6 раза большим,
чем давление, создаваемое при использовании
обычных хладагентов. Если компоненты трубо-
проводов не предназначены для использования
с хладагентом R410A, и аппарат установлен не-
правильно, трубы могут лопнуть и причинить по-
вреждение или нанести травму. Кроме того, это
может привести к утечке воды, поражению элек-
трическим током или возникновению пожара.
• При установке прибора в целях безопасности
используйте соответствующие защитное обо-
рудование и инструменты. Невыполнение этого
требования может привести к травмам.
• Прибор должен быть установлен согласно ин-
струкциям, чтобы свести к минимуму риск по-
вреждения от землетрясений, тайфунов или
сильных порывов ветра. Неправильно установ-
ленный прибор может упасть и причинить по-
вреждение или нанести травму.
• Прибор должен быть установлен на конструк-
ции, способной выдержать его вес. Прибор,
установленный на неустойчивой конструкции,
может упасть и причинить повреждение или на-
нести травму.
• Если наружный прибор установлен в небольшом
помещении, необходимо принять меры для пре-
дотвращения концентрации хладагента свыше
безопасных пределов в случае утечки хладаген-
та. Проконсультируйтесь у дилера относительно
соответствующих мер, предотвращающих пре-
вышение допустимой концентрации. В случае
утечки хладагента и превышении допустимой
его концентрации из-за нехватки кислорода в по-
мещении может произойти несчастный случай.
• Если во время работы прибора произошла утеч-
ка хладагента, проветрите помещение. При кон-
такте хладагента с пламенем образуются ядови-
тые газы.
Осторожно:
• Не выпускайте R410A в атмосферу:

• Все электроработы должны выполняться ква-
лифицированным техническим специалистом в
соответствии с местными правилами и инструк-
циями, приведенными в данном Руководстве.
Приборы должны быть подключены к специ-
ально выделенным линиям электропитания с
соответствующим напряжением через автома-
тические выключатели. Использование линий
электропитания недостаточной мощности или
неправильно проведенных линий может приве-
сти к поражению электрическим током или воз-
никновению пожара.
• Для соединения медных или медносплавных
бесшовных труб, предназначенных для хлада-
гента, используйте медный фосфор C1220. Если
трубы соединены неправильно, прибор не будет
должным образом заземлен, что может приве-
сти к поражению электрическим током.
• Используйте для проводки указанные кабели.
Убедитесь, что кабели надежно соединены, а
оконечные соединения не натянуты. Никогда не
соединяйте кабели внахлест (если иное не ука-
зано в прилагаемой документации). Несоблюде-
ние этих инструкций может привести к перегреву
или возгоранию.
•
Крышка наружного прибора должна быть надеж-
но присоединена к прибору. Если крышка уста-
новлена неправильно, в прибор могут попасть
пыль и влага, что может привести к поражению
электрическим током или возникновению пожара.
• При монтаже или перемещении, а также при об-
служивании наружного прибора используйте
только указанный хладагент (R410A) для запол-
нения трубопроводов хладагента. Не смешивай-
те его ни с каким другим хладагентом и не допу-
скайте наличия воздуха в трубопроводах.
Наличие воздуха в трубопроводах может вызы-
вать скачки давления, в результате которых мо-
жет произойти взрыв или другие повреждения.
Использование любого хладагента, отличного от
указанного для этой системы, вызовет механиче-
ское повреждение, сбои в работе системы, или
выход устройства из строя. В наихудшем случае,
это может послужить серьезной преградой к обе-
спечению безопасной работы этого изделия.
• Используйте только те дополнительные принад-
лежности, на которые имеется разрешение от
Mitsubishi Electric; для их установки обратитесь
к дилеру или уполномоченному техническому
специалисту. Неправильная установка допол-
нительных принадлежностей может привести к
протечке воды, поражению электрическим то-
ком или возникновению пожара.
• Не изменяйте конструкцию прибора. При необхо-
димости ремонта обратитесь к дилеру. Если из-
менения или ремонт выполнены неправильно,
это может привести к протечке воды, удару элек-
трическим током или возникновению пожара.
• Пользователю не следует пытаться ремонтиро-
вать прибор или перемещать его на другое ме-
сто. Если прибор установлен неправильно, это
может привести к утечке воды, удару электри-
ческим током или возникновению пожара. Если
необходимо отремонтировать или переместить
наружный прибор, обратитесь к дилеру или
уполномоченному техническому специалисту.
• По окончании установки убедитесь в отсутствии
утечки хладагента. Если хладагент проникнет в
помещение и произойдет контакт его с пламенем
обогревателя или переносного пищевого нагре-
вателя, образуются ядовитых газов.
• При открытии или закрытии клапана при темпе-
ратуре ниже температуры замерзания хладагент
может выплеснуться из зазора между штоком и
корпусом клапана, из-за чего возможны травмы.

1. Меры предосторожности
1.2. Перед установкой (перемещением)
Осторожно:
• Соблюдайте особую осторожность при транс-
портировке или установке приборов. Прибор
должны переносить два или более человека, по-
скольку он весит не менее 20 кг. Не поднимайте
прибор за упаковочные ленты. При извлечении
прибора из упаковки или при его перемещении
используйте защитные перчатки, во избежание
травмирования рук о пластины или о другие вы-
ступающие части.
• Утилизируйте упаковочные материалы надлежа-
щим образом. Упаковочные материалы, такие,
как гвозди и другие металлические или деревян-
ные части, могут поранить или причинить дру-
гие травмы.
1.3. Перед электрическими работами
Осторожно:
• Обязательно установите автоматические вы-
ключатели. В противном случае возможно пора-
жение электрическим током.
• Используйте для электропроводки стандарт-
ные кабели, рассчитанные на соответствующую
мощность. В противном случае может произойти
короткое замыкание, перегрев или пожар.
• При монтаже кабелей питания не прикладывай-
те растягивающих усилий. Если соединения
ненадежны, кабель может отсоединиться или
порваться, что может привести к перегреву или
возникновению пожара.
• Необходимо периодически производить провер-
ку основного блока наружного прибора и уста-
новленных на нем компонентов на разболтан-
ность, наличие трещин или других повреждений.
Если такие дефекты оставить неисправленны-
ми, прибор может упасть и причинить поврежде-
ние или нанести травму.
• Не мойте наружный прибор водой. Это может
привести к поражению электрическим током.
•
Затягивайте все хомуты на муфтах в соответствии
со спецификациями, используя ключ с регулируе-
мым усилием. Слишком сильно затянутый хомут
муфты по прошествии некоторого времени может
сломаться, что вызовет утечку хладагента.
• Обязательно заземлите прибор. Не присо-
единяйте провод заземления к газовым или
водопроводным трубам, громоотводам или
телефонным линиям заземления. Отсутствие
надлежащего заземления может привести к по-
ражению электрическим током.
•
Используйте автоматические выключатели (преры-
ватель утечки тока на землю, разъединитель (плав-
кий предохранитель +B) и предохранитель корпуса)
с указанным предельным током. Если предельный
ток автоматического выключателя больше, чем не-
обходимо, может произойти поломка или пожар.
1.1. Перед установкой
Осторожно:
•
Не используйте прибор в нестандартной окружа-
ющей среде. Установка наружного прибора в ме-
стах, подверженных воздействию пара, летучих
масел (включая машинное масло) или сернистых
испарений, местах с повышенной концентраци-
ей соли (таких, как берег моря), или местах, где
прибор будет засыпан снегом, может привести к
значительному снижению эффективности работы
прибора или повреждению его внутренних частей
.
• Не устанавливайте прибор в местах, где возмож-
на утечка, возникновение, приток или накопле-
ние горючих газов. Если горючий газ будет нака-
пливаться вокруг прибора, это может привести к
возникновению пожара или взрыву.
• При использовании режима обогрева на наруж-
ном приборе образуется конденсат. Удостоверь-
тесь, что обеспечен хороший дренаж в районе
наружного прибора, если этот конденсат может
принести какой-либо вред.
• Снимите с компрессора элемент фиксации в
соответствии с прикрепленным к прибору УВЕ-
ДОМЛЕНИЕМ. При использовании прибора с
установленным элементом фиксации будет на-
блюдаться повышение уровня шума.
•
При монтаже прибора в больнице или центре связи
примите во внимание шумовое и электронное воз-
действие. Работа таких устройств, как инверторы,
бытовые приборы, высокочастотное медицинское
оборудование и оборудование радиосвязи может
вызвать сбои в работе наружного прибора или его
поломку. Наружный прибор также может повлиять на
работу медицинского оборудования и медицинское
обслуживание, работу коммуникационного оборудо-
вания, вызывая искажение изображения на дисплее
.
•
Во время работы прибора от удлинительных труб
может быть слышен шум движущегося хладагента
или вибрация. Старайтесь по возможности не
устанавливать трубопроводы на тонких стенах и т. п.,
а также не забывайте обеспечивать звукоизоляцию с
помощью крышки трубопровода и т. п
.
