Wiring Connection How to connect the connecting cable Wiring of the connecting cable can be carried out without removing the front panel. 1. Insert the connecting cable (according to the local cords) into the pipe hole on the wall. Take out the connecting cable through the cable slot on the rear panel so that it protrudes about 15 cm from the front. Insert the connecting cable fully into the terminal block and secure it tightly with screws. Fix the terminal cover, rear plate bushing and air inlet grille on the indoor unit. 1. Die-cutting Front panel slit Cut out the slit on the left or right side of the front panel for the left or right connection and the slit on the bottom left or right side of the front panel for the bottom left or right connection with a pair of nippers. 2. Changing drain hose For left connection, left-bottom connection and rear-left connection's piping, it is necessary to change the drain hose and drain cap. How to remove the Drain Cap Clip drain cap by needle-nose plier, and pull out. CAUTION · Be sure to refer to the wiring system diagram labeled inside the front panel. · Check local electrical cords and also any specific wiring instructions or limitations.

Heat insulator How to fix the Drains Cap Screw Earth wire 4 mm 1) Insert hexagonal wrench (4 mm) in a center head. Connecting cable Screw NOTE · Wire type : More than H07RN-F or 245IEC66 (1. 0 mm2 or more) 80 mm 10mm 10mm 2) Firmly insert drains cap. No gap Do not apply lubricating oil (refrigerant machine oil) when inserting the drain cap. Insert a hexagon wrench (4 mm) Earth line Connecting cable 3 abou 2 t 15 cm 1 10mm 50 mm Fig. · Carefully connect the auxiliary pipes and connecting pipes to each other and cut off the insulating tape wound on the connecting pipe to avoid double-taping at the joint, moreover, seal the joint with the vinyl tape, etc. · Since dewing results in a machine trouble, make sure to insulate both the connecting pipes. (Use polyethylene foam as insulating material. ) · When bending a pipe, carefully do it not to crush it. Fig. Setting of Remote Controller Selector Switch When two indoor units are installed in the separated rooms, there is no need to change the select switches. (1) Stop the operation of the air conditioner and turn turn off its main power supply. (2) Pull the air inlet grille toward you to open it and remove the air inlet grille. (3) First open the horizontal louver and then remove the front panel from the back body by pulling it toward you. Remote Controller Selector Switch · When two indoor units are installed in the same room or adjacent two rooms, if operating a unit, two units may receive the remote controller signal simultaneously and operate. In this case, the operation can be preserved by setting either one indoor unit and remote controller to B setting (Both are set to A setting in factory shipment). · The remote control signal is not received when the settings of indoor unit and remote controller are different. · There is no relation between A setting/B setting and A room/B room when connecting the piping and cables. Position of Remote Control Selector Switch 1. Setting of remote controller switch at the indoor unit side How to remove the front cabinet Fig. 9-2-20 How to mount the front panel Push the front panel back in and make sure all hook are locked. Adhesion of B label (When setting to [B]) Be sure to affix the B label on the front panel same as the below figure. Fig. [. . . ] 2) Remove the front cabinet, and put it down so that fan guard side directs downward. Minus screwdriver Perform work on a corrugated cardboard, cloth, etc. 3) Remove the hooking claws by pushing minus screwdriver according to the arrow mark in the right figure, and remove the fan guard. Attachment 1) Insert claw of the fan guard in the hole of the front cabinet. Check that all the hooking claws are fixed to the specified positions. Hooking claw ­ 78 ­ No. 11 Part name Replacement of temperature sensor for servicing only Procedure Remarks 1) Cut the sensor 100 mm longer than old one. [. . . ]
