PRECAUTIONS FOR SAFETY
• Ensure that all Local, National and International regulations are satisfied.
• Read this “PRECAUTIONS FOR SAFETY” carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DE-
STROY OZONE LAYER.
The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure
is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil
has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust
does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance
force and impurity in it.
CAUTION
To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of
at least 3 mm.
The installation fuse (25A D type
) must be used for the power supply line of this conditioner.
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may be damaged.
• When moving the air conditioner for the installation into another place, be very careful not
to enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnor-
mally high and it may resultingly causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the
safety interlock switches.
• Exposure of unit to water or other moisture before installation may cause short-circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.
4
• After unpacking the unit, examine it carefully if there are possible damage.
• Do not install in a place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• When the air conditioner is installed in a small room, provide appropriate measures to
ensure that the concentration of refrigerant leakage occur in the room does not exceed the
critical level.
• Install the air conditioner securely in a location where the base can sustain the weight
adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas
might generate.
• Electrical work must be performed by a qualified electrician in accordance with the Installa-
tion Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified cables for wiring connect the terminals securely fix. To prevent external
forces applied to the terminals from affecting the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible
gas.
If a combustible gas leaks, and stays around the unit, a fire may occur.

With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge (Evacuate air in
the connecting pipes) when installing the unit.
• Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.
• Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains, the capacity
may decrease.
For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump does not backflow
into the pipe of the air conditioner when the pump stops. (If oil in the vacuum pump is put in an air conditioner
including R410A, it may cause trouble on the refrigeration cycle.)
Vacuum pump
As shown in the right figure, connect the charge hose after the manifold valve are closed completely.
Attach the connecting port of the charge hose with a projection to push the valve core (setting pin) to the charge port of the set.
Open the handle Low fully.
Turn ON the vacuum pump (*1)
Loosen the flare nut of the packed valve (Gas side) a little to check the air passes through. (*2)
Tighten the flare nut again.
Execute vacuuming until the compound pressure gauge indicates –101kPa (–76cmHg). (*1)
Close handle Low completely.
Turn OFF the vacuum pump.
Leave the vacuum pump as it is for 1 or 2 minutes, and check the indicator of the compound pressure gauge does not return.
Open fully the valve stem or the valve handle. (First, at liquid side, then gas side)
Disconnect the charge hose from the charge port.
Tighten valve and caps of the charge port surely.

FINAL INSTALLATION CHECKS
Check and Test Operation
Valve cover
For R410A, use the leak detector exclusively manufactured for
HFC refrigerant (R410A, R134a, etc.).
Piping
cover
The conventional leak detector for HCFC refrigerant (R22,
etc.) cannot be used because its sensitivity for HFC refrigerant
lowers to approx. 1/40.
*
Flare nut
connections
(Indoor unit)
• Pressure of R410A is approx. 1.6 times higher than that of
R22.
If installation work is incompletely finished, a gas leakage may
occur when pressure rises during operation.
Therefore, be sure to test the piping connections for leakage.
Check points
of outdoor unit
• Check gas leakage at the flare nut connections, valve stem
cap connections and service port cap fittings with a leak
detector or soap water.
CAUTION
When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power
supply has been turned on.
It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx. 1 minute is required to start the operation by the remote controller.
Useful Functions (SM800AT-E only)
Self-Diagnosis by LED Indication
In addition to the code checking by remote controller of the indoor unit, troubles of the outdoor unit can be diag-
nosed by LED indications on the cycle control P.C. board of the outdoor unit. Utilize them for various checks.
For the check by remote controller of the indoor unit, refer to the Installation Manual of the indoor unit.
Before a check, confirm each bit of the DIP switch is set to OFF position.

Installation/ServicingTools
Changes in the product and components
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged acciden-
tally, service port diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads
per inch)
• In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of
opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)
New tools for R410A
New tools for R410A

Changes
As pressure is high, it is impossible to measure by means of conventional
gauge. In order to prevent any other refrigerant from being charged, each
port diameter is changed.

PRECAUTIONS FOR SAFETY
• Ensure that all Local, National and International regulations are satisfied.
• Read this “PRECAUTIONS FOR SAFETY” carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DE-
STROY OZONE LAYER.
The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure
is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil
has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust
does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance
force and impurity in it.
CAUTION
To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of
at least 3 mm.
The installation fuse (25A D type
) must be used for the power supply line of this conditioner.
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may be damaged.
• When moving the air conditioner for the installation into another place, be very careful not
to enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnor-
mally high and it may resultingly causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the
safety interlock switches.
• Exposure of unit to water or other moisture before installation may cause a short-circuit of
electrical parts.

• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• When the air conditioner is installed in a small room, provide appropriate measures to
ensure that the concentration of refrigerant leakage occur in the room does not exceed the
critical level.
• Install the air conditioner securely in a location where the base can sustain the weight
adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas
might generate.
• Electrical work must be performed by a qualified electrician in accordance with the Installa-
tion Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified cables for wiring connect the terminals securely fix. To prevent external
forces applied to the terminals from affecting the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible
gas.

With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge (Evacuate air in
the connecting pipes) when installing the unit.
• Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.
• Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains, the capacity
may decrease.
For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump does not backflow
into the pipe of the air conditioner when the pump stops. (If oil in the vacuum pump is put in an air conditioner
including R410A, it may cause trouble on the refrigeration cycle.)
Vacuum pump
As shown in the right figure, connect the charge hose after the manifold valve are closed completely.
Attach the connecting port of the charge hose with a projection to push the valve core (setting pin) to the charge port of the set.
Open handle Low fully.
Turn ON the vacuum pump (*1)
Loosen the flare nut of the packed valve (Gas side) a little to check the air passes through. (*2)
Tighten the flare nut again.
Execute vacuuming until the compound pressure gauge indicates –101kPa (–76cmHg). (*1)
Close handle Low completely.
Turn OFF the vacuum pump.
Leave the vacuum pump as it is for 1 or 2 minutes, and check the indicator of the compound pressure gauge does not return.
Open fully the valve stem or the valve handle. (First, at liquid side, then gas side)
Disconnect the charge hose from the charge port.

FINAL INSTALLATION CHECKS
Check and Test Operation
For R410A, use the leak detector exclusively manufactured for HFC refrigerant (R410A, R134a, etc.).
The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC
refrigerant lowers to approx. 1/40.
*
• Pressure of R410A is approx. 1.6 times higher than that of R22.
If installation work is incompletely finished, a gas leakage may occur when pressure rises during operation.
Therefore, be sure to test the piping connections for leakage.
• Check gas leakage at the flare nut connections, valve stem cap connections and service port cap fittings with a
leak detector or soap water.
CAUTION
When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power
supply has been turned on.
It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx. 1 munute is required to start the operation by the remote controller.
Useful Functions
Self-Diagnosis by LED Indication
In addition to the code checking by remote controller of the indoor unit, troubles of the outdoor unit can be diag-
nosed by LED indications on the cycle control P.C. board of the outdoor unit. Utilize them for various checks.
For the check by remote controller of the indoor unit, refer to the Installation Manual of the indoor unit.
Before a check, confirm each bit of the DIP switch is set to OFF position.

FINAL INSTALLATION CHECKS
Installation/ServicingTools
Changes in the product and components
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged acciden-
tally, service port diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads
per inch)
• In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of
opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)
New tools for R410A
New tools for R410A
Applicable to R22 model
Changes
As pressure is high, it is impossible to measure by means of conventional
gauge. In order to prevent any other refrigerant from being charged, each
port diameter is changed.
Gauge manifold
×
In order to increase pressure resisting strength, hose materials and port
size are changed (to 1/2 UNF 20 threads per inch).
When purchasing a charge hose, be sure to check the port size.

WARNINGS ABOUT OPERATION
• Cleaning of the air filter and other parts of the air filter involves dangerous work in
high places, so be sure to have a service person do it. Do not attempt it yourself.
The cleaning diagram for the air filter is there for the service person, and not for
the customer.
• Avoid cooling the room too strong or exposing the human body to cool breeze for
a long time as it is bad for the health.
• When you notice something abnormal with the air conditioner (smells like some-
thing scorching, poor cooling, etc.), immediately turn off the main switch, the
circuit breaker, from the mains to stop the air conditioner, and contact the dealer.
If the air conditioner is continuously operated with something abnormal, it may
cause machine failure, electric shock, fire, and so on.
WARNINGS ABOUT MOVEMENT AND REPAIR
• Do not move or repair any unit by yourself.
Since there is high voltage inside the unit, you may get electric shock when
removing the cover and main unit.
• Whenever the air conditioner needs repair, make sure to ask the dealer to do it.
If it is repaired imperfectly, it may cause electric shock or fire.
• When moving the air conditioner for re-installing at another place, ask the dealer
to do it. If it is imperfectly installed, it may cause electric shock or fire.

CAUTION
CAUTIONS ABOUT INSTALLATION
• Be sure to confirm the following cautions.
• Certainly lay the drain hose for perfect draining.
Bad drainage may cause flooding in the house and getting furniture
wet.
• Make sure to connect the air conditioner to an exclusive power
supply of the rated voltage, otherwise the unit may break down or
cause a fire.
• Do not install the unit in a place where inflammable gas may leak.
If inflammable gas accumulates around the unit, it may cause a fire.
CAUTIONS ABOUT OPERATION
• Carefully read this manual before starting the air conditioner. There
are many important things to keep in mind for daily operation.
• Do not use this air conditioner for special purposes such as preserv-
ing food, precision instruments, art objects, breeding animals,
growing potted plants, etc.
• Avoid exposing potted plants and animals to the wind of the air
conditioner, since it badly affects the health and growth of them.
• When the air conditioner is operated with a combustion appliance in
the same place, be careful of ventilation to let fresh air enter the

Checks before operation
(1) Check that the air filters are installed.
(2) Check that the air outlet or inlet is not blocked.
(3) Turn on the main power switch or the circuit breaker for the main
power supply to the air conditioner.
FAN ONLY operation
WARNING
Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure
to have a service person do it. Do not attempt it yourself.
NOTE
For Air conditioning system which is operated regularly, cleaning and maintenance of the indoor/outdoor
units are strongly recommended.
As a general rule, if an indoor unit is operated for about 8 hours daily, the indoor/outdoor units will need to
be cleaned at least once every 3-MONTH. This cleaning and maintenance shall be carried out by a
qualified person.
Failure to clean the indoor/outdoor units regularly will result in poor performance, icing, water leaking and
even compressor failure.
40
AIR CONDITIONER OPERATIONS AND PERFORMANCE
3 minutes protection function
3-minutes protection function prevents the air conditioner from starting for initial 3 minutes after the main
power switch/circuit breaker is turned on for re-starting the air conditioner.
Power failure
Power failure during operation will stop the unit completely.
• To restart the operation, push the START/STOP button on the remote controller.
• Lightning or a wireless car telephone operating nearby may cause the unit to malfunction. Turn off the main
power switch or circuit breaker and then turn them on again. Push the START/STOP button on the remote
controller to restart.
Heating characteristics
Preheating operation
The air conditioner will not deliver warm air immediately after it is turned on. Warm air will start to flow out
after approximately 5 minutes when the indoor heat exchanger warmed up.
Warm air control (In heating operation)
When the room temperature reaches the set temperature, the fan speed is automatically reduced to prevent
to blow cold draft. At this time, the outdoor unit will stop.
Defrosting operation
If the outdoor unit is frosted during the heating operation, defrosting starts automatically (for approximately
2 to 10 minutes) to maintain the heating capacity.
• The fans in both indoor and outdoor units will stop during the defrosting operation.
• During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor
unit.
Heating capacity
In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating
is called heat pump system. When the outside temperature is too low, it is recommended to use another
heating apparatus in combination with the air conditioner.
Attention to snowfall and freeze on the outdoor unit
• In snowy areas, the air inlet and air outlet of the outdoor unit are often covered with snow or frozen up.
If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming.
• In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside
for freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine
failure or poor warming.

PRECAUTIONS FOR SAFETY
• Ensure that all Local, National and International regulations are satisfied.
• Read this “PRECAUTIONS FOR SAFETY” carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT
DESTROY OZONE LAYER.
The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure
is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil
has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does
not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force
and impurity in it.
CAUTION
To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of
at least 3 mm.
The installation fuse (25A D type
) must be used for the power supply line of this conditioner.
WARNINGS
• Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may be damaged.
• When moving the air conditioner for the installation into another place, be very careful not
to enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes
abnormally high and it may resultingly causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the
safety interlock switches.
• Exposure of unit to water or other moisture before installation may cause a short-circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.
46
• After unpacking the unit, examine it carefully if there are possible damage.
• Do not install in a place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• When the air conditioner is installed in a small room, provide appropriate measures to
ensure that the concentration of refrigerant leakage occur in the room does not exceed the
critical level.
• Install the air conditioner securely in a location where the base can sustain the weight
adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might
generate.
• Electrical work must be performed by a qualified electrician in accordance with the
Installation Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified cables for wiring connect the terminals securely fix. To prevent external
forces applied to the terminals from affecting the terminals.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible
gas.
If a combustible gas leaks, and stays around the unit, a fire may occur.

SELECTION OF INSTALLATION PLACE
WARNING
• Install the air conditioner at enough strong place to withstand the weight of the unit.
If the strength is not enough, the unit may fall down resulting in injury.
• Install the air conditioner at a height 2.5m or more from the floor.
If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous
because you may contact with revolving fan or active electricity.
CAUTION
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and stays around the unit, a fire may occur.
Upon approval of the customer, install the air conditioner in a place that satisfies the following conditions.
• Place where the unit can be installed horizontally.
• In the process after removing the ceiling panel, it important to reinforce the groundwork (framework) and keep
a level correctly of the existing ceiling to prevent vibration of the ceiling panel.
• Place where a sufficient servicing space can be ensured for safety maintenance and check.
• Place where drained water will not cause any problem.
Avoid installing in the following places.
• Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas
(hot spring). (Should the unit be used in these places, special protective measures are needed.)
• Place exposed to oil, vapor, oil smoke or corrosive gas.
• Place where organic solvent is used nearby.
• Place close to a machine generating high frequency.
• Place where the discharged air blows directly into the window of the neighboring house. (For outdoor unit)
• Place where noise of the outdoor unit is easily transmitted.
(When installing the air conditioner on the boundary with the neighbor, pay due attention to the level of noise.)
• Place with poor ventilation. (Before air ducting work, check whether value of air volume, static pressure and
duct resistance are correct.)

Installation reference
(Example for RAV-SM801BT model)
The air supply ducting work is classified in two ways, one is branched by the round ducts, and the other is branched
by the square ducts. (Be sure to divide the air supply duct into three or more branches.)
<Round duct>
<Square duct> (Reference for square duct)
When using the square duct, change the type of the air
supply flange from round type to square flange at the
local site.
In case of the round duct, use the thermal insulator of
thickness 25mm or more and inner diameter 150mm
or more to the duct board.
(If the inner diameter is not enough, resistance
increase, as the result, air does not flow smoothly and
loss of the static pressure increases.) For the thermal
insulator, use high-density glass wool of 24kg/m3 or
equivalent.
In case of the square duct, apply the thermal insulator
of thickness 25mm or more to the duct board. For the
thermal insulator, use high-density glass wool of
weight 64kg/m3.
Density of thermal
insulator (glass wool) is
24 kg/m³ or equivalent.

Points at installation work
n General cautions
1. Considering installation places of indoor unit supply chamber, structure of the building and determine the duct
path.
2. In order to utilize the static pressure characteristics of the air supply in the indoor unit, design the duct branching
having the large size of the air supply chamber or setting distance to the first branch as long as possible
(Min. : 200mm or longer) so that an even air volume can be obtained.
Especially, when branching just after air supply of the indoor unit, air concentrates at the center part and is
difficult to flow to the ducts at both sides.
3. Connect each connecting section surely, and apply sufficient thermal insulation.
In this model of which the duct is branched in the ceiling, compared with the model for ordinary houses, the high
temperature generates on the periphery in the cooling time (Especially, at attic and etc.), temperature difference
increases between the supply air and outside of the duct, and dewing may occur.
Dewing on the surface of the thermal insulator covering the metal connecting section or leaking portion of the
cooled air may cause a trouble such as water drops.
4. Thermal insulation of screwing sections is necessary.
Prevent dewing by applying thermal insulation to 6 screws those fix the duct flange of the air supply chamber.
• For duct parts, the flexible branch duct (thermal insulation, 25mm or more thickness) is recommended.
• Adjust the duct length to 6m or less even for straight pipe, and avoid sharp bending (Air flow resistance is
large.) if bending.
56
Hanging of indoor unit
Nut
Lift up the unit with a lifter, etc., and set the hanging metal in the
hanging bolt.
• Hook nut of the hanging bolt to the groove of the hanging metal on
the main unit.
Washer
Hanging bolt
Hanging bracket
• Using the level, etc., install the main unit horizontally.
Failure to do this will cause water leakage
Mounting of filter and canvas for suction port
1. Mount a long-life filter or a high-performance filter according to each Installation Manual.
2. Mount the canvases for suction port to the lower side of the above filter.
Mounting of remote controller
For the mounting of the wired remote controller, refer to the Installation Manual attached to the remote controller.
• Take out the remote controller cord together with the refrigerant pipe or drain pipe. Be sure to set the remote
controller cord so that it passes through the upper side of the refrigerant pipe and drain pipe.
