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.
ENGLISH
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.

PRECAUTIONS FOR SAFETY
• 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.
• 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.)

AIR DUCTING WORK
Installation Reference (exp. for RAV-SM800BT-E 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>
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/m
equivalent.
Density of thermal
insulator (glass wool) is
25mm or more
24 kg/m³ or equivalent.
Ø150mm or more
3
or
<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/m
