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: • 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). • Connect indoor and outdoor units with field-supplied copper pipes by means of flare connections. Use insulated seamless refrigeration grade pipe only, (Cu DHP type according to ISO1337), degreased and deoxidized, suitable for operating pressures of at least 4200 kPa and for burst pressure of at least 20700 kPa. Under no circumstances must sanitary type copper pipe be used. Moreover, do not use the existing piping because there are problems with pressure-resistance force and impurity in it. • Check that the impedance of the mains power supply is in conformance with the unit power input indicated in the electric data (EN 61000-3-11). • This unit complies with low-voltage (EEC/73/23) and electromagnetic compatibility (EEC/89/336) directives. • This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm. ) must be used for The installation fuse (25A D type the power supply line of this conditioner. 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 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 cause 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 for 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. GB - 2 • 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 occurred 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 correctly, 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 and connect them firmly to the terminals. To prevent external forces applied to the terminals 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 a combustible gas. If a combustible gas leaks, and stays around the unit, a fire may occur.
