1. PRECAUTIONS FOR SAFETY
For general public use
Power supply cord of Outdoor unit shall be more than 2.5mm²(H07RN-F or 245 IEC66) polychloroprene
sheathed flexible cord.
•Read this “Precautions for Safety”carefully before servicing.
•The precautions described below include the important items regarding safety. Observe them without fail.
•After the servicing work, perform a trial operation to check for any problem.
•Turn off the main power supply switch (or breaker) before the unit maintenance.
CAUTION New Refrigerant Air Conditioner Servicing
• THIS AIR CONDITIONER ADOPTSTHE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT
DESTROY OZONE LAYER.
The characteristics of R410A refrigerant is easy to absorb water, oxidizing membrane or oil, and its pressure
is approx.1.6 times of refrigerant R22. Accompanied with adoption of the new refrigerant, refrigerating oil
has been also changed. Therefore, during servicing work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter into the refrigerating cycle of new refrigerant air conditioner.
To prevent from mixing of refrigerant and refrigerating oil, the sizes of connecting sections of charging port of
the main unit or installation tools are different 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 materials with high pressure-tight force, which were made for
R410A only, so that water or dust does not enter. Moreover, do not use the existing piping because there are
problems about pressure-tight force and impurity it.
CAUTION To Disconnect the Appliance from the Main Power Supply.
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a
contact separation of at least 3 mm.
If this is not possible, a power supply plug with grounding must be used. This plug must be easily accessible
after installation. The plug must be disconnected from the power supply socket in order to disconnect the
appliance completely from the mains.
The installation fuse (25A D type ) must be used for the power supply line of this air
conditioner.
WARNINGS
• Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate servicing 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 by wrong way, electric parts may be damaged.
• When moving the air-conditioner for installing it in another place again, be very careful not to
get the specified refrigerant (R410A) with any other gaseous body 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 resultingly causes burst of the pipe and injuries on persons.

•Never 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 servicing may cause a short circuit.
Do not store it in a wet basement or expose to rain or water.
•After unpacking the unit, examine it carefully for possible damage.
•Do not install in a place that can increase the vibration of the unit.
•To avoid personal injury, be careful when handling parts with sharp edges.
•Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
•When installing the air conditioner in a small room, provide appropriate measures to ensure
that the concentration of refrigerant in the room does not exceed the critical level should
leakage occur.
It is not dangerous refrigerant;it has not toxicity or combustibility. However, a concentration above 0.3kg/m³
as criterion still causes suffocation. The volume of refrigerant charged to the Multi System air conditioner is
more than the volume charged to a conventional individual system.
•Install the air conditioner securely in a location where the weight of the unit can be sustained
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 servicing 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
may generate.
•The electrical work must be performed by a qualified electrician in accordance with the Instal-
lation Manual. Make sure the air conditioner uses an exclusive circuit.
An insufficient circuit capacity or inappropriate installation may cause fire.
•When wiring, use the specified cables and connect the terminals securely to prevent external
forces applied to the cable 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 combustible
gas.
Otherwise, the combustible gas may leak and a fire may occur.
