PRECAUTIONS FOR SAFETY

Power supply cord of Outdoor unit shall be 2.5mm² (H07RN-F or 245 IEC66) polychloroprene sheathed flexible
cord.
• 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 to the customer how to use and maintain the unit.
• 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
• THIS AIR CONDITIONER ADOPTS THE 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 installation 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
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
• 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 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 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.
