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.
Usage
(Be sure to hand over to customers)
For insulating pipe connecting section
For hanging down the unit
For connecting drain pipe
For adjustment of drain pipe centering
For insulating drain connecting section
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.
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 wire correctly.
If the connecting wire 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 as a result 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.
• 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 wires 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.
