2. Maximum allowable voltage variation between phases is 2%.
3. Select wire size based on the larger value of MCA.
4. Instead of fuse, use circuit breaker.
5. Be sure to install an earth leak detector. (One that can handle
higher harmonics.)
(This unit uses an inverter, which means that it must be used an
earth leak detector capable handling high harmonics in order to
prevent malfunctioning of the earth leak detector itself.

12.1.1 Safety Precautions
SAFETY PRECAUTIONS
• Read these Safety Precautions carefully to ensure correct installation.
• This manual classifies the precautions into WARNING and CAUTION.
Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNING...............Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.
CAUTION...............Failure to follow any of CAUTION may in some cases result in grave consequences.
• The following safety symbols are used throughout this manual:
Be sure to observe this instruction.
Be sure to establish an earth connection.
Never attempt.
• After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use and cleaning of the unit
according to the Operation Manual.
WARNING
• Installation should be left to the dealer or another professional.
Improper installation may cause water leakage, electrical shock, or fire.
• Install the air conditioner according to the instructions given in this manual.
Incomplete installation may cause water leakage, electrical shock, or fire.
• Be sure to use the supplied or specified installation parts.
Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or fire.
• Install the air conditioner on a solid base that can support the weight of the unit.
An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
• Electrical work should be carried out in accordance with the installation manual and the national electrical wiring
rules or code of practice. Insufficient capacity or incomplete electrical work may cause electrical shock or fire.
• Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
• For wiring, use a cable length enough to cover the entire distance with no connection.
Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock or fire.)
• Use the specified types of wires for electrical connections between the indoor and outdoor units.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.
• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force
on the electrical covers or panels.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire.
• When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the
specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
• If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to flames.)
• After all installation is complete, check to make sure that no refrigerant is leaking out.
(The refrigerant produces a toxic gas if exposed to flames.)
• During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the shut-off valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.
• During installation, attach the refrigerant piping securely before running the compressor.
If the compressor is not attached and the shut-off valve is open during pump-down, air will be sucked in when the compressor is run, causing
abnormal pressure in the freezer cycle which will lead to breakage and even injury.
• When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into
refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.
• Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth.
Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks, or fire.
CAUTION
• Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage.
If the gas leaks and builds up around the unit, it may catch fire.
• Establish drain piping according to the instructions of this manual.
Inadequate piping may cause flooding.
• Tighten the flare nut according to the specified method such as with a torque wrench.
If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage.

12.2.1 Safety Precautions
Safety Precautions
• Read these Safety Precautions carefully to ensure correct installation.
• This manual classifies the precautions into WARNING and CAUTION.
Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNING
Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.
CAUTION
Failure to follow any of CAUTION may result in grave consequences in some cases.
• The following safety symbols are used throughout this manual:
Be sure to observe this instruction.
Be sure to establish an earth connection.
Never attempt.
• After completing installation, test the unit to check for installation errors. Give the user adequate instructions
concerning the use and cleaning of the unit according to the Operation Manual.
WARNING
• Installation should be left to the dealer or another professional. Improper installation may cause water leakage, electrical shock, or fire.
• Install the air conditioner according to the instructions given in this manual. Incomplete installation may cause water leakage, electrical shock, or fire.
• Be sure to use the supplied or specified installation parts. Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or fire.
• Install the air conditioner on a solid base that can support the weight of the unit. An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
• Electrical work should be carried out in accordance with the installation manual and the national electrical wiring
rules or code of practice. Insufficient capacity or incomplete electrical work may cause electrical shock or fire.
• Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
• For wiring, use a cable length enough to cover the entire distance with no connection. Do not use an extension cord.
Do not put other loads on the power supply, use a dedicated power circuit. (Failure to do so may cause abnormal heat, electric shock or fire.)
• Use the specified types of wires for electrical connections between the indoor and outdoor units. When installing
wiring for the outdoor unit, after cutting the wires for each connection point, a length of 3mm or longer is required.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.
• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force on the electrical covers or panels.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire. When electrical appliances are connected in Y formation,
if the power supply is damaged in some way, to avoid danger the power supply must be replaced by the maker or by someone with an equivalent certification.
• When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the specified
refrigerant (R410A), such as air. (Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
• If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to flames.)
• After all installation is complete, check to make sure that no refrigerant is leaking out.
(The refrigerant produces a toxic gas if exposed to flames.)
• During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during
pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.
• During installation, attach the refrigerant piping securely before running the compressor. If the compressor is not attached and the stop valve is
open during pump-down, air will be sucked in when the compressor is run, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.
• Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth.
Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.
• Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks, or fire.
CAUTION
• Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage.
If the gas leaks and builds up around the unit, it may catch fire.
• Establish drain piping according to the instructions of this manual. Inadequate piping may cause flooding.
• Tighten the flare nut according to the specified method such as with a torque wrench. If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage.
• Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.

Precautions for Selecting the Location
1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will
not be amplified.
2) Choose a location where the hot air discharged from the unit or the operation noise will not cause a
nuisance to the neighbors of the user.
3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.
4) There must be sufficient spaces for carrying the unit into and out of the site.
5) There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
6) The site must be free from the possibility of flammable gas leakage in a nearby place.
7) Install units, power cords and inter-unit cables at least 3 meter away from television and radio sets. This is
to prevent interference to images and sounds. (Noises may be heard even if they are more than 3 meter
away depending on radio wave conditions.)
8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the
air conditioner.
9) Since drain flows out of the outdoor unit, do not place under the unit anything which must be kept away
from moisture.
NOTE
Cannot be installed hanging from ceiling or stacked.
CAUTION
When operating the air conditioner in a low outdoor ambient
temperature, be sure to follow the instructions described below.
1) To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
2) Never install the outdoor unit at a site where the suction side
may be exposed directly to wind.
3) To prevent exposure to wind, it is recommended to install a
baffle plate on the air discharge side of the outdoor unit.
4) In heavy snowfall areas, select an installation site where the
snow will not affect the unit.
Construct a large canopy.
Construct a pedestal.
Install the unit high enough off the
ground to prevent burying in snow.
Precautions on Installation
20
• Check the strength and level of the installation ground so that the unit will not cause any operating vibration
or noise after installed.
• In accordance with the foundation drawing, fix the unit securely by means of the foundation bolts. (Prepare
four sets of M8 or M10 foundation bolts, nuts and washers each which are available on the market.)
• It is best to screw in the foundation bolts until their length are 20mm from the foundation surface.

It is a mixed refrigerant, so adding it in gas form may cause the
refrigerant composition to change, preventing normal operation.
1) Before filling, check whether the cylinder has a siphon attached or not.
(It should have something like “liquid filling siphon attached” displayed on it.)
Filling a cylinder with an
attached siphon
Filling other cylinders
Stand the cylinder upright
when filling.
Turn the cylinder
upside-down when filling.
There is a siphon pipe
inside, so the cylinder
need not be upsidedown to fill with liquid.
• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.

3)
4)
Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle.
To prevent air pollution, a vacuum pump should be used for air purging wherever possible.
Refrigerant gas leaks during air purging, ventilate the room as soon as possible.
Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants
may damage the vacuum pump or the unit.
• If using additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a
vacuum pump, then charge additional refrigerant.
• Use a hexagonal wrench (4mm) to operate the stop valve rod.
• All refrigerant pipe joints should be tightened with a torque wrench at the specified tightening torque.
1) Connect projection side of charging hose (which comes from gauge manifold) to gas stop valve’s service port.
2) Fully open gauge manifold’s low-pressure valve (Lo) and completely close its high-pressure valve (Hi).
(High-pressure valve subsequently requires no operation.)
3) Do vacuum pumping and make sure that the compound pressure gauge reads – 0.1MPa (– 76cmHg)*1.
4) Close gauge manifold’s low-pressure valve (Lo) and stop vacuum pump.
(Keep this state for a few minutes to make sure that the compound pressure gauge pointer does not swing back.)*2.
5) Remove covers from liquid stop valve and gas stop valve.
6) Turn the liquid stop valve’s rod 90 degrees counterclockwise with a hexagonal wrench to open valve.
Close it after 5 seconds, and check for gas leakage.
Using soapy water, check for gas leakage from indoor unit’s flare and outdoor unit’s flare and valve rods.
After the check is complete, wipe all soapy water off.
7) Disconnect charging hose from gas stop valve’s service port, then fully open liquid and gas stop valves.
(Do not attempt to turn valve rod beyond its stop.)
8) Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the specified torques.

Operation Manual
Trouble Shooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Case
Explanation
Operation does not start soon.
• When ON/OFF button was
pressed soon after
operation was stopped.
• When the mode was
reselected.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
The outdoor unit emits water or
steam.
„ In COOL or DRY mode
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
Mist comes out of the indoor
unit.
„ This happens when the air in the room is cooled into mist by
the cold air flow during cooling operation.
„ This is because the air in the room is cooled by the heat
exchanger and becomes mist during defrost operation.
The indoor unit gives out odour. „ This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged with the
air flow.
(If this happens, we recommend you to have the indoor unit
washed by a technician. Consult the service shop where you
bought the air conditioner.)
The outdoor fan rotates while
the air conditioner is not in
operation.
„ After operation is stopped:
• The outdoor fan continues rotating for another 60
seconds for system protection.
„ While the air conditioner is not in operation:
• When the outdoor temperature is very high, the outdoor
fan starts rotating for system protection.
The operation stopped
suddenly.
(OPERATION lamp is on.)
„ For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

„ About batteries
• When replacing the batteries, use batteries of the same type, and replace the two old batteries
together.
• When the system is not used for a long time, take the batteries out.
• We recommend replacing once a year, although if the remote controller display begins to fade or if
reception deteriorates, please replace with new alkali batteries. Using manganese batteries reduces
the lifespan.
• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air
conditioner.

Use this when making the noise quieter.
The unit might lose capacity when the air flow rate is set to a weak level.
NOTE
„ Note on HEAT operation
• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating
capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is
recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the
start of heating operation, it takes some time before the room gets warmer.
• In heating operation, frost may occur on the outdoor unit and lower the heating capacity. In that case,
the system switches into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of indoor unit.
„ Note on COOL operation
• This air conditioner cools the room by blowing the hot air in the room outside, so if the
outside temperature is high, performance drops.
„ Note on DRY operation
• The computer chip works to rid the room of humidity while maintaining the temperature as
much as possible. It automatically controls temperature and fan strength, so manual
adjustment of these functions is unavailable.
„ Note on AUTO operation
• In AUTO operation, the system selects a temperature setting and an appropriate operation mode
(COOL or HEAT) based on the room temperature at the start of the operation.
• The system automatically reselects setting at a regular interval to bring the room temperature to
user-setting level.
• If you do not like AUTO operation, you can manually select the operation mode and setting

Operation Manual
Trouble Shooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Case
Explanation
Operation does not start soon.
• When ON/OFF button was
pressed soon after
operation was stopped.
• When the mode was
reselected.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
Hot air does not flow out soon
after the start of heating
operation.
• The air conditioner is warming up. You should wait for 1 to 4
minutes.
(The system is designed to start discharging air only after it
has reached a certain temperature.)
The heating operation stops
suddenly and a flowing sound
is heard.
• The system is taking away the frost on the outdoor unit.
You should wait for about 4 to 12 minutes.
The outdoor unit emits water or
steam.
„ In HEAT mode
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
„ In COOL or DRY mode
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
Mist comes out of the indoor
unit.
„ This happens when the air in the room is cooled into mist by
the cold air flow during cooling operation.
„ This is because the air in the room is cooled by the heat
exchanger and becomes mist during defrost operation.
The indoor unit gives out odour. „ This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged with the
air flow.
(If this happens, we recommend you to have the indoor unit
washed by a technician. Consult the service shop where you
bought the air conditioner.)
The outdoor fan rotates while
the air conditioner is not in
operation.
„ After operation is stopped:
• The outdoor fan continues rotating for another 60
seconds for system protection.
„ While the air conditioner is not in operation:
• When the outdoor temperature is very high, the outdoor
fan starts rotating for system protection.
The operation stopped
suddenly.
(OPERATION lamp is on.)
„ For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

If one of the following symptoms takes place, call the service shop immediately.
The power cord is abnormally hot or damaged.
An abnormal sound is heard during operation.
The safety breaker, a fuse, or the earth leakage breaker
cuts off the operation frequently.
A switch or a button often fails to work properly.
There is a burning smell.
Water leaks from the indoor unit.
„ After a power failure
The air conditioner automatically resumes
operation in about 3 minutes. You should just
wait for a while.
Turn the breaker
OFF and call the
service shop.
„ Lightning
If lightning may strike the neighboring area,
stop operation and turn the breaker OFF for

Disposal requirements
Dismantling of the unit, treatment of the refrigerant, oil and eventual other parts, should be done in accordance with
the relevant local and national regulations.
We recommend periodical maintenance.
In certain operating conditions, the inside of the air conditioner may get foul after several seasons of

ensuring safety.
WARNING
• Installation should be left to the dealer or another qualified professional.
Improper installation by yourself may cause malfunction, electrical shock, or fire.
• Install the set according to the instructions given in this manual.
Incomplete or improper installation may cause malfunction, electrical shock, or fire.
Precaution
1.When reading the Operating / error signals, a separate external power source
(DC 12V) is needed.
2.A separate timer power source (DC 16V) is needed when using the schedule
timer independently, and not in conjunction with other central controllers.
3.The range of temperatures that can be set from the central controller is 18°C to
32°C in cooling and 14°C to 28°C in heating.
4.Fan operation cannot be selected from the central controller or wired remote controller.
5.Group control (i.e., control of multiple indoor units with a single remote controller) is
not available.
6.Monitoring is not available of the thermo status, compressor operating status,
indoor fan operating status, electric heater, or humidifier operating status.
7.Forced thermo off, filter sign display and reset, fan direction and speed settings,
air conditioning fee management, energy savings instructions, low-noise
instructions, and demand instructions cannot be made.
• Be sure to use the standard attachments or the genuine parts.
Use of other parts may cause malfunction, electrical shock, or fire.
• Disconnect power to the connected equipment before starting installation.
Failure to do so may cause malfunction, electrical shock, or fire.
CAUTION
• An earth leakage circuit breaker should be installed.
If the breaker is not installed, electrical shock may occur.
• Do not install the set in a location where there is danger of exposure to
inflammable gas.
Gas accumulated around the unit at the worst may cause fire.

Recommended power source: Omron S82J-01015A. (Should be used with the
output voltage adjusted to the center, DC 16V.)
(3) Settings when recovering from a power outage (SW2-4)
This selects whether to restart operation when the power comes back on after a
power outage occurred during operation. This setting is given priority in cases
where the indoor unit has an auto start ON / OFF jumper. Note also that
regardless of whether switch SW2-4 is on or off, the operating mode, set
temperature, fan direction and speed settings, and remote control prohibition
status are stored.

What Happens
NOTE1: Since central equipment and HA JEM-A-compatible equipment both use
last command priority, the contact status and operating status of the air
conditioner might not match sometimes.
Example: If the unit is run from the central controller while the air
conditioner is stopped with an open contact, the contact will be
open and the unit will be running.
NOTE2: Operating mode and fan direction and speed settings can be changed.
