• 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.
PRECAUTIONS FOR SAFETY
CAUTIONNew 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.
CAUTIONTo 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 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 short-circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.

• 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.

• The indoor/outdoor connecting pipes can be connected to 4 directions.
Take off the knock out part of the pipe cover in which
pipes or wires pass through the base plate.
• As shown in the figure, do not remove the pipe cover
from the cabinet so that the knockout hole can be
easily punched. To knock out, it is easily taken off by
hands by punching a position at the lower side of 3
connected parts with screwdriver along the guideline.
• After marking the knockout hole, remove the burr and
mount the attached protective bush and guard
material for pass-through part in order to protect
pipes and wires.
How to remove the front panel
1. Remove scre ws of the front panel.
2. Pull the front panel downward.
Removing the front panel, the electric parts appear at
the front side.
• The metal pipes are attachable to the piping holes.
If the size of the used power pipe does not match
with the hole, adjust the hole size to match with pipe
size.
• Be sure to fix the power cable and indoor/outdoor
connecting cable with bundling band sold on the
market so that they do not mak e contact with the
compressor and discharge pipe.
(Temperature of the compressor and discharge pipe
becomes high.)
In order to avoid the force applied to on the connecting section, be sure to fix the cables to the cord
clamps provided on the pipe valve fixing plate and the
electric parts box.

EVACUATING
Air Purge
This air conditioner can be installed up to the connecting pipe length and height difference in the following table.
Capacity rank
SM560 type
SM800 type
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 .)

FINAL INSTALLATION CHECKS
Check and Test Operation
For R410A, use the leak detector e xclusiv ely 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 appro x. 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

Installation/Servicing T ools
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, 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)

• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the
U.S. ’s ARI specified rose color (ARI color code: PMS 507).
• Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to
the charge hose’s port size.

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.
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.
As pressure is high and gasification speed is fast, it is difficult to read the
indicated value by means of charging cylinder, as air bubbles occur.
The sizes of opposite sides of flare nuts have been increased. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8.
By increasing the clamp bar’s receiving hole, strength of spring in the tool
has been improved.
Used when flare is made with using conventional flare tool.
Connected to the conventional vacuum pump. It is necessary to use an
adapter to prevent vacuum pump oil from flowing back to the charge hose.
The charge hose connecting part has two ports - one for conventional
refrigerant (7/16 UNF 20 threads per inch) and the other for R410A. If the
vacuum pump oil (mineral) mixes with R410A, sludge may occur and
damage the equipment.

PRECAUTIONS FOR SAFETY
CAUTIONNew Refrigerant Air Conditioner Installation
RAV-SM1100AT-E
RAV-SM1400AT-E
• 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.
CAUTIONTo 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 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.

• The indoor/outdoor connecting pipes can be connected to 4 directions.
Take off the knock out part of the pipe cover in which
pipes or wires pass through the base plate.
• As shown in the figure, do not remove the pipe cover
from the cabinet so that the knockout hole can be
easily punched. To knock out, it is easily taken off by
hands by punching a position at the lower side of 3
connected parts with screwdriver along the guide
line.
• After marking the knockout hole, remove the burr and
mount the attached protective bush and guard
material for pass-through part in order to protect
pipes and wires.
For Reference
If a heating operation would be continuously performed
for a long time under the condition that the outdoor
temperature is 0°C or lower, draining of defrosted water
may be difficult due to freezing of the bottom plate,
resulting in a trouble of the cabinet or fan.
It is recommended to procure an anti-freeze heater
locally for a safety installation of the air conditioner.
For details, contact the dealer.
After connecting the pipes, be sure to mount the pipe
cover. The pipe cover is easily mounted by cutting off
the slit at the lower part of the pipe cover.

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 .)

FINAL INSTALLATION CHECKS
Check and Test Operation
For R410A, use the leak detector e xclusiv ely 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, b ut is because the setup of the remote controller is being checked.
For the second pow er-ON time and after, approx. 1 munute is required to start the operation by the remote controller.
Useful Functions
In addition to the code checking by remote controller of the indoor unit, troub les of the outdoor unit can be diagnosed 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/Servicing T ools
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, 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)

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.
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.
As pressure is high and gasification speed is fast, it is difficult to read the
indicated value by means of charging cylinder, as air bubbles occur.
The size of opposite sides of flare nuts have been increased. Incidentally,
a common wrench is used for nominal diameters 1/4 and 3/8.

• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the
U,S. ’s ARI specified rose color (ARI color code: PMS 507).
• Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to
the charge hose’s port size.

Used when flare is made with using conventional flare tool.
Connected to the conventional vacuum pump. It is necessary to use an
adapter to prevent vacuum pump oil from flowing back to the charge hose.
The charge hose connecting part has two por ts-one for conventional
refrigerant (7/16 UNF 20 threads per inch) and one for R410A.
If the vacuum pump oil (mineral) mixes with R410A a sludge may occur
and damage the equipment.

AIR CONDITIONER OPERATIONS AND PERFORMANCE
3 minutes protection function
3-minutes protection function prev ents the air conditioner from starting for initial 3 minutes after the main
power switch/circuit break er is turned on for re-starting the air conditioner .
Power failure
Po wer 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 e xchanger w armed 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.
Air conditioner operating conditions
For proper perf ormance, operate the air conditioner under the following temperature conditions:
CoolingOutdoor temperature: –5°C to 43°C

PRECAUTIONS FOR SAFETY
CAUTIONNew 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.
CAUTIONTo 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.

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>
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.
Density of thermal
insulator (glass wool) is
25mm or more
24 kg/m³ or equivalent.
Ø150mm or more
<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 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.

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
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.
• Using the level, etc., install the main unit horizontally.
Failure to do this will cause water leakage
Washer

Nut
Hanging bracket
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.

REFRIGERANT PIPING
Refrigerant piping
1. If the outdoor units are to be mounted on a wall,
make sure that the supporting platform is
sufficiently strong. The platform should be
designed and manufactured to maintain its strength
over a long period of time, and sufficient
consideration should be given to ensuring that the
outdoor unit will not fall.
2. Use copper pipe with 0.8 mm or more
thickness.
3. Flare nut and flare works are also different from
those of the conventional refrigerant.
Take out the flare nut attached to the main unit of
the air conditioner, and use it.
CAUTION
IMPORTANT 4 POINTS FOR PIPING WORK
1. Remove dust and moisture from the inside of
the connecting pipes.
2. Tight connection (between pipes and unit)

EVACUATING
AIR PURGE
Evacuate the air in the connecting pipes and in the
indoor unit using vacuum pump.
Do not use the refrigerant in the outdoor unit.
For details, see the manual of vacuum pump.
Use a vacuum pump
Be sure to use a vacuum pump with counter-flow
prevention function so that inside oil of the pump does
not flow backward into pipes of the air conditioner
when the pump stops.
1. Connect the charge hose from the manifold valve
to the service port of the gas side packed valve.
2. Connect the charge hose to the port of vacuum
pump.
3. Open fully the low pressure side handle of the
gauge manifold valve.
4. Operate the vacuum pump to start evacuating.
Perform evacuating for about 35 minutes if the
piping length is 30 meters total for model SM560
and 50 meters for model SM800, SM1100, SM1400
(assuming a pump capacity of 27 liters per minute.)
Then confirm that the compound pressure gauge
reading is –101 kPa ( –76 cmHg).
5. Close the low pressure side valve handle of gauge
manifold.
6. Open fully the valve stem of the packed valves
(both sides of Gas and Liquid).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
Open valve fully
Open valves of the corresponding outdoor units fully.
Gas leak check
Using a lead detector or soap water, check there is no
gas leak from pipe connecting portion or caps of the
valves.
REQUIREMENT
For a leak detector, use one manufactured
exclusively for HFC refrigerant (R410A, R134a, etc.)
Thermal-insulating process
Perform pipe thermal-insulating process for liquid and
gas sides separately.
• For thermal insulator to pipes at gas side, use one
with heat resisting temperature 120°C or higher.
• Using the attached thermal insulator, perform surely
thermal insulation without gap for pipe connecting
portion of the indoor unit.
REQUIREMENT
Perform surely thermal insulation process so that
the naked end of pipe connecting portion of the
indoor unit does not appear.
(Exposure of the pipe may cause water leak.)
Packed valve handling precautions
• Open the valve stem all the way out ; do not try to
open it beyond the stopper.
• Securely tighten the valve stem cap at the torque as
follows:
15.9 mm (diam.)
12.7 mm (diam.)
9.5 mm (diam.)
6.4 mm (diam.)
68 to 82 N•m (6.8 to 8.2 kgf•m)
50 to 62 N•m (5.0 to 6.2 kgf•m)
33 to 42 N•m (3.3 to 4.2 kgf•m)
14 to 18 N•m (1.4 to 1.8 kgf•m)
Hexagonal wrench is required.
