• 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.
PRECAUTIONS FOR SAFETY
ENGLISH
CAUTION
• 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
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.
• 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.
New refrigerant air conditioner installation
To disconnect the appliance from main power supply
WARNING
• 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.

• 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.

For addition of the refrigerant, add refrigerant “R410A” referring to the attached Installation Manual of outdoor unit.
Be sure to use a scale to charge the refrigerant of specified amount.
REQUIREMENT
• Charging an excessive or too little amount of refrigerant causes a trouble of the compressor.
Be sure to charge the refrigerant of specified amount.
• A personnel who charged the refrigerant should write down the pipe length and the added refrigerant amount
in the nameplate attached to the service panel of the outdoor unit. It is necessary to troubleshoot the
compressor and refrigeration cycle malfunction.
Open the valve fully
Open the valve of the outdoor unit fully. A 4 mm hexagonal wrench is required for opening the valve.
For details, refer to the Installation Manual attached to the outdoor unit.
Gas leak check
Check with a leak detector or soap water whether gas leaks or not, from the pipe connecting section or cap of the
valve.
REQUIREMENT
Use a leak detector manufactured exclusively for HFC refrigerant (R410A, R134a, etc.).
Thermal insulation process
Apply thermal insulation for the pipes separately at liquid side and gas side.
For the thermal insulation to the pipes at gas side, be sure to use the material with heat-resisting temperature
120°C or higher.
Using the attached thermal insulation material, apply the thermal insulation to the pipe connecting section of the
indoor unit securely without gap.
REQUIREMENT
Apply the thermal insulation to the pipe connecting section of the indoor unit securely up to the root without
exposure of the pipe. (The pipe exposed to the outside causes water leak.)
