1.2. Precautions for devices that use
R410A refrigerant
1.4. Before installation (relocation) electrical work
• Do not use existing refrigerant piping.
- The old refrigerant and refrigerant oil in the existing piping contains a large
amount of chlorine which may cause the refrigerant 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.
• 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 refrigerant 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 refrigerant 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 refrigerant 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 refrigerant oil are mixed in the R410A,
the refrigerant may deteriorated.
- If water is mixed in the R410A, the refrigerant 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.
• 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.
• Never connect in reverse phases.
Never connect the Power Line L1, L2, and L3 to Terminal N.
- If the unit is miss wired, when power is supplied, some electrical parts will
be damaged.
• 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, 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.
- Tear apart and throw away plastic packaging bags so that children will not
play with them. If children play with a plastic bag which has not been torn
apart, they face the risk of suffocation.

Caution:
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.
Caution:
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.
2. About the product
• This unit uses R410A-type refrigerant.
• 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.
• 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.
12
• 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.
Caution:
• Do not vent R410A into the atmosphere.
• R410A is a Fluorinated Greenhouse gas, covered by the Kyoto Protocol
with a Global Warming Potential (GWP) = 1975.

<B> With detachable leg
M10 anchor bolt procured at the site. B Corner is not seated.
Fixing bracket for the hole-in anchor bolt (3 locations to fix with screws).
Detachable leg
• Fix unit tightly with bolts so that unit will not fall down due to earthquakes or
strong winds.
• Use concrete or an angle bracket as the foundation of unit.
• Vibration may be transmitted to the installation section and noise and
vibration may be generated from the floor and walls, depending on the
installation conditions. Therefore, provide ample vibrationproofing (cushion
pads, cushion frame, etc.).
• Build the foundation in such way that the corner of the installation leg is
securely supported as shown in the figure. (Fig. 8.1.1)
When using a rubber isolating cushion, please ensure it is large enough to
cover the entire width of each of the unit's legs. If the corners are not firmly
seated, the installation feet may be bent.
• The projecting length of the anchor bolt should be less than 30 mm.
• Hole-in anchor bolts are not compatible with this product. However, if fixing
brackets are mounted on the 4 locations (6 locations: P450, EP300) of the
unit attachment part, hole-in anchor bolts can be used.
• The detachable leg can be removed at the site.
• Detaching the detachable leg
Loosen the three screws to detach the detachable leg (Two (three: P450,
EP300) each in the front and back).
If the base leg finish is damaged when detaching, be sure to repair at the
site.
Warning:
• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a
personal injury.
• Have installation work in order to protect against strong winds and
earthquakes.
Any installation deficiency may cause unit to fall down, resulting in a
personal injury.
When building the foundation, give full attention to the floor strength, drain water
disposal <during operation, drain water flows out of the unit>, and piping and
wiring routes.
Precautions when routing the pipes and wires below the unit (Without
detachable leg)
When routing the pipes and wires below the unit, be sure that the foundation and
base work do not block the base through-holes. Also make sure the foundation
is at least 100 mm high so that the piping can pass under the unit.
9. Refrigerant piping installation
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 and liquid pipes for outdoor units, brazed connection. Note that
the branched sections are brazed.
Warning:
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.
Caution:
• Do not vent R410A into the atmosphere.
• R410A is a Fluorinated Greenhouse gas, covered by the Kyoto Protocol
with a Global Warming Potential (GWP) = 1975.
9.1. Caution
This unit uses refrigerant R410A. Follow the local regulations on materials and
pipe thickness when selecting pipes. (Refer to the table on the right.)
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).
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 radii as big as possible.
5 For indoor and outdoor branching, be sure to use the following twinning pipe
sets (sold separately).

- Mixing of water will cause the refrigerant 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 refrigerant oil will deteriorate.
Never use existing refrigerant piping.
- The large amount of chlorine in conventional refrigerant and refrigerant 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.

b 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 10.4 for thermal insulation of refrigerant piping).
c 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.
[Fig. 9.2.2] (P.6)
<A> Make sure the pipes from the twinning pipe to the outdoor unit are sloped
downwards (towards the twinning pipes).
<B> When the piping on the outdoor unit side (from the twinning pipe) exceeds 2 m,
ensure a trap (gas pipe only) within 2 m. Make sure the height of the trap is
200 mm or more.
If there is no trap, oil can accumulate inside the pipe, causing a shortage of
oil and may damage the compressor.

Warning:
When installing and moving the unit, do not charge the system with any
other refrigerant other than the refrigerant specified on the unit.
- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to
malfunction and may result in severe damage.
Caution:
10.Additional refrigerant charge
At the time of shipping, the outdoor unit is charged with refrigerant.
This charge does not include the amount needed for extended piping and
additional charging of 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.
10.1.Calculation of additional refrigerant
charge
• 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 right as a guide to calculating the amount of additional
charging and charge the system accordingly.

The pipe sizes listed in columns A1 to A3 in this table correspond to the sizes
for the models listed in the unit 1, 2, and 3 columns. When the order of the
models for unit 1, 2, and 3 change, make sure to use the appropriate pipe size.
Precautions for outdoor unit combinations
Refer to [Fig. 9.2.2] for the positioning of twinning pipes.
d 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 10.2. for details of the piping connection and valve operation)
• 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 refrigerant 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 refrigerant oil may cause the
refrigerant oil to deteriorate.

10.2.Precautions concerning piping
connection and valve operation
• Conduct piping connection and valve operation accurately and carefully.
• Removing the pinched connecting pipe
When shipped, a pinched connecting pipe is attached to the on-site liquid
and gas valves to prevent gas leakage.
Take the following steps 1 through 4 to remove the pinched connecting
pipe before connecting refrigerant pipes to the outdoor unit.
1 Check that the refrigerant service valve is fully closed (turned clockwise
all the way).
2 Connect a charging hose to the service port on the liquid/gas refrigerant
service valve, and extract the gas in the pipe section between the
refrigerant service valve and the pinched connecting pipe.
3 After vacuuming gas from the pinched connecting pipe, sever the
pinched connecting pipe at the location shown in [Fig.10.2.1] and drain
the refrigerant.
4 After completing 2 and 3 heat the brazed section to remove the
pinched connecting pipe.

Warning:
• The sections between the refrigerant service valves and the pinched
connecting pipes are filled with gas and refrigerant oil. Extract the gas
and refrigerant oil in the above-mentioned pipe section before heating
the brazed section to remove the refrigerant service valve pinched
connecting pipe.
- If the brazed section is heated without first extracting the gas and
refrigerant oil, the pipe may burst or the pinched connecting pipe may blow
off and ignite the refrigerant oil, causing serious injury.
•
Caution:
Place a wet towel on the refrigerant service valve before heating the brazed
section to keep the temperature of the valve from exceeding 120 ˚C.
• Direct the flame away from the wiring and metal sheets inside the unit
to prevent heat damage.
Caution:
• Do not vent R410A into the atmosphere.
• R410A is a Fluorinated Greenhouse gas, covered by the Kyoto
Protocol, with a Global Warming Potential (GWP) = 1975.
• Refrigerant pipe connection
This product includes connecting pipes for front piping and bottom postpiping. (Refer to [Fig.10.2.2])
Check the liquid/gas piping dimensions before connecting the refrigerant pipe.
Refer to item 9.2 Refrigerant piping system for piping dimensions.
Make sure that the refrigerant pipe is not touching other refrigerants pipes,
unit panels, or base plates.
Be sure to use non-oxidative brazing when connecting pipes.
Be careful not to burn the wiring and plate when brazing.

• After evacuation and refrigerant charging, 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.
17
• 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 so as not to
generate any gas leakage. (Refer to the table on the below for appropriate
tightening torque.)

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. 10.2.3] (P.7)
A Example of closure materials (field supply)
B Fill the gap at the site
Make sure to seal-off the space around areas where the wires and refrigerant
pipes enter the unit to ensure that small animals, rainwater, or snow cannot
enter the unit through such openings and cause damage to the unit.
Caution:
Make sure to seal-off the openings for the pipe and wire retrieval.
• Small animals, rainwater, or snow entering through the openings may
cause damage to the device.
Airtight test procedure
Restriction
(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 (Gupoflex, etc.) and visually check for bubbles.
(3) After the airtight test, wipe off the bubbling agent.
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.
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.

• If a flammable gas or air (oxygen) is used as the pressurization
gas, it may catch fire or explode.
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.10.3.3. 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.
[Fig. 10.3.3] (P.8)
A Syphon pipe
10.4.Thermal insulation of refrigerant piping
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.

* Installation of pipes in a high-temperature high-humidity environment, such
as the top floor of a building, may require the use of insulation materials
thicker than the ones specified in the chart above.
GB
* When certain specifications presented by the client must be met, ensure that
they also meet the specifications on the chart above.
11.Wiring (For details, refer to the installation manual of each unit and controller.)
11.1. Caution
1 Follow ordinance of your governmental organization for technical standard
related to electrical equipment, wiring regulations and guidance of each
electric power company.
2 Wiring for control (hereinafter referred to as transmission line) shall be (5 cm or more) apart from power source wiring so that it is not influenced by
electric noise from power source wiring (Do not insert transmission line and
power source wire in the same conduit).
3 Be sure to provide designated grounding work to the outdoor unit.
4 Give some allowance to wiring for electrical part box of indoor and outdoor
units, because the box is sometimes removed at the time of service work.
5 Never connect the main power source to terminal block of transmission line.
If connected, electrical parts will burn out.
6 Use 2-core shield cable for transmission line. If transmission lines of different
systems are wired with the same multiplecore cable, the resultant poor
transmitting and receiving will cause erroneous operations.
7 Only the transmission line specified should be connected to the terminal
block for outdoor unit transmission.
Erroneous connection does not allow the system to operate.
8 In the case of connecting with an upper class controller or to conduct group
operation in different refrigerant systems, the control line for transmission is
required between the outdoor units in different refrigerant systems.
Connect this control line between the terminal blocks for centralized control
(2-wire line with no polarity).
9 Group is set by operating the remote controller.
11.2.Control box and connecting position

1. Remove the front panel of the control box by removing the 4 screws and
pushing it up a little before pulling it out.
2. Connect the indoor - outdoor transmission line to the terminal block (TB3) for
the indoor - outdoor transmission line.
If multiple outdoor units are connected in the same refrigerant system, daisyTerminal) on the outdoor units. Connect the indoor chain TB3 (M1, M2,
Terminal)
outdoor transmission line for the outdoor units to TB3 (M1, M2,
of only one of the outdoor units.
3. Connect the transmission lines for centralized control (between the
centralized control system and the outdoor unit of different refrigerant
systems) to the terminal block for centralized control (TB7). If the multiple
outdoor units are connected to the same refrigerant system, daisy-chain TB7
(M1, M2, S Terminal) on the outdoor units in the same refrigerant system.
(*1)
*1: If TB7 on the outdoor unit in the same refrigerant system is not daisychained, connect the transmission line for centralized control to TB7 on
the OC (*2). If the OC is out of order, or if the centralized control is being
conducted during the power supply shut-off, daisy-chain TB7 on the OC,
OS1, and OS2 (In the case that the outdoor unit whose power supply
connector CN41 on the control board has been replaced with CN40
is out of order or the power is shut-off, centralized control will not be
conducted even when TB7 is daisy-chained).
*2: OC, OS1, and OS2 of the outdoor units in the same refrigerant system
are automatically identified. They are identified as OC, OS1, and OS2 in
descending order of capacity (If the capacity is the same, they will be in
ascending order of their address number).
4. In the case of indoor-outdoor transmission line, connect the shield ground to
the grounding terminal ( ). In the case of transmission lines for centralized
control, connect it to the shield terminal (S) on the terminal block for
centralized control (TB7). Furthermore, in the case of the outdoor units
whose power supply connector CN41 is replaced with CN40, short circuit the
shield terminal (S) and the grounding terminal ( ) in addition to the above.
5. Fix the connected wires securely in place with the cable strap at the bottom
of the terminal block. External force applied to the terminal block may
damage it resulting in a short circuit, ground fault, or a fire.

Use dedicated power supplies for the outdoor unit and indoor unit. Ensure OC and OS are wired individually.
Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.
The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter.
Make sure the power-supply voltage does not drop more than 10%.
Specific wiring requirements should adhere to the wiring regulations of the region.
Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57).
A switch with at least 3 mm contact separation in each pole shall be provided by the Air Conditioner installer.
Warning:
• Be sure to use specified wires for connections and ensure no external force is imparted to terminal connections. If connections are not fixed firmly,
heating or fire may result.
• Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
• Some installation sites may require attachment of an earth leakage breaker for the inverter. If no earth leakage breaker is installed, there is a danger of
electric shock.
• Do not use anything other than a breaker and fuse with the correct capacity. Using a fuse or wire of too large capacity may cause malfunction or fire.
Note:
• This device is intended for the connection to a power supply system with a maximum permissible system impedance shown in the above table at the
interface point (power service box) of the user’s supply.
• The user must ensure that this device is connected only to a power supply system which fulfils the requirement above. If necessary, the user can ask the public power supply company for the system impedance at the interface point.
• This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc (*2) at the interface point between
the user’s supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution
network operator if necessary, that the equipment is connected only to a supply with a short-circuit power Ssc greater than or equal to Ssc (*2).

12.1.The following phenomena do not represent faults.
GB
Phenomenon
Indoor unit does not perform cooling
(heating) operation.
The auto vane rotates and begins to blow air
horizontally.
Display of remote controller
“Cooling (heating)” flashes
Normal display
Fan setting changes during heating.
Normal display
Fan stops during heating operation.
Fan does not stop while operation has been
stopped.
No setting of fan while start SW has been
turned on.
Defrost display
No lighting
Indoor unit remote controller shows “H0”
or “PLEASE WAIT” indicator for about five
minutes when turning ON universal power
supply.
Drain pump does not stop when unit is
stopped.
Drain pump continues to operate while unit
has been stopped.
Indoor unit emits noise when switching from
heating to cooling and vice versa.
Immediately after startup, the indoor unit
emits the sound of the refrigerant flow.
Warm air comes from an indoor unit that is
not performing a heating operation.
“H0” or “PLEASE WAIT” flashes
Heat ready
Light out
Cause
When another indoor unit is performing the heating (cooling) operation, the
cooling (heating) operation is not performed.
If air has been blowing downward for 1 hour during cooling, the unit may
automatically change to horizontal blowing with the control operation of the
auto vane. During defrosting or immediately after heating start-up/shut-down,
the auto vane automatically rotates to blow air horizontally for a short period
of time.
Ultra-low speed operation is commenced at thermostat OFF.
Light air automatically changes over to set value by time or piping temperature
at thermostat ON.
The fan is to stop during defrosting.
The fan is set to run for 1 minute after stopping to exhaust residual heat (only in
heating).
Ultra low-speed operation for 5 minutes after SW ON or until piping
temperature becomes 35°C, low speed operation for 2 minutes thereafter, and
then set notch is commenced (Hot adjust control).
The system is being started up.
Operate remote controller again after “H0” or “PLEASE WAIT” disappear.
After cooling operation stops, the unit continues to operate drain pump for
three minutes and then stops it.
Unit continues to operate drain pump if drainage is generated, even during a
stop.
This is a switching sound of the refrigerant circuit and does not imply a
problem.
Unstable flow of the refrigerant emits a sound. This is temporary and does not
imply a problem.
The LEV is slightly open to prevent refrigerant, of the indoor unit that is not
performing the heating operation, from being liquefied. This does not imply a
problem.
