The figures quoted are emission level and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e. the number of equipment and other adjacent processes and the length of time for which an operator exposed to the noise. Also, the permissible exposure level can vary from country to country. This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk. Limiting concentration (for R410A) Limiting concentration is the limit of Freon gas concentration where immediate measures can be taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall be described in the unit of kg/m3 (Freon gas weight per unit air volume) for facilitating calculation. Limiting concentration: 0.44 kg/m3(R410A) n Calculate refrigerant concentration Total amount of replenished Refrigerant refrigerant in refrigerant facility (kg) concentration = Capacity of smallest room where 3 (kg/m ) indoor unit is installed (m3) IMPORTANT SAFETY INSTRUCTIONS 3 Read the precautions in this manual carefully before operating the unit.

When none are available, follow the instructions below. - Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power wiring may cause abnormal heat.) - When connecting wiring which is the same thickness, do as shown in the figure below. Connect same thickness wiring to both sides. It is forbidden to connect two to one side. It is forbidden to connect wiring of different thicknesses. • If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer of its service agent. - For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being exerted on the terminal block. - Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small head will strip the head and make proper tighterning impossible. - Over-tightening the terminal screws may break them. ENGLISH ! 16 MAINTENANCE ENGLISH MAINTENANCE When the air conditioner is not going.... Clean the product regularly to maintain optimal performance and to prevent possible breakdown. When air conditioner is not going to be used for a long time. 1 Operate the air conditioner at the following settings for 2 to 3 hours. • Type of operation: Fan operation mode.(Refer to page "Fan Mode") • This will dry out the internal mechanisms. ! CAUTION • Turn off the power and unplug the power cord before you perform any maintenance; otherwise it may cause electric shock. • Never use water that is hotter than 40 °C when you clean the filters. It may cause deformation or discoloration. • Never use volatile substances when you clean the filters. They may damage the surface of the product. Operation Tips! • Do not overcool the room. This is not good for the health and wastes electricity. • Keep blinds or curtains closed.
