Process them so that they do not touch any electrical or metal parts. Stripping length of power cord 90mm 10mm Earth line N L 10mm 80mm NOTE · Use standard wire only. · Wire type : 3, 5 mm² or more AWG-12. · Do not apply excess torque. Otherwise, the nut may crack depending on the conditions. CAUTION Valve body Valve stem 5m m ­ 19 ­ Fig. 8-4-8 WARNING To plug the cable in the plug receptacle, take the following precaution.

Refrigerant Piping Connection Flaring 1. Cut the pipe with a pipe cutter. 90° Obliquity Roughness Warp Fig. 8-4-5 10mm 50mm Connecting cable CAUTION · KEEP IMPORTANT 4 POINTS FOR PIPING WORK (1)Take away dust and moisture (Inside of the connecting pipes. ) (2)Tight connection (between pipes and unit) (3)Evacuate the air in the connecting pipes using VACUUM PUMP. (4)Check gas leak (connected points) A Fig. 8-4-9 As the colors of the flexible cord of this appliance may not correspond with the colored markings, to identify terminals in your plug, as follows : Connect BROWN colored core to plug terminal marked letter "L". Power Supply Voltage The line voltage must be AC 220­240V (RAS18YKH-E, RAS-18YAH-E), 240V (RAS-18YKH-A, RL938). If the line voltage is not within this range, this air conditioner may not work normally. 9-1-3. Misleading but Good Operations (Program Controlled Operation) The microcomputer performs the operations listed in Table 9-1-1 to control the air conditioner. If a claim is made on the operation, check whether it corresponds to the contents in the Table 9-1-1. If it does, it is an indispensable operation for the control and maintenance of the air conditioner: it is not a failure of the unit. Table 9-1-1 No. 1 Operation of air-conditioner When the breaker is turned on, the OPERATION lamp on the setting indication part flashes. Fan speed remains unchanged in the dry mode. Room temperature is in the range under which the compressor is turned off, but the compressor will not stop. The compressor will not switch on or off even when the thermo control is operated in the dry operation. lamp comes on when the heating operation is started. Description The OPERATION lamp flashes, indicating that power is turned on. [. . . ] YES NO Short-circuit the metal terminal at the side of the battery compartment (all-clear terminal) with a pencil. (wait about 10 seconds) Is there any thyristor fluorescent light near by?YES NO NO Is operation possible when the transmitter is moved nearer to the infrared signal receiver of the air conditioner?YES Battery life Push the START/ STOP button NO Is operation possible when setting the temporary switch of the air conditioner main unit to "TEST RUN" or "TEMPORARY AUTO"?
