[. . . ] 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. Tightening torque : 1. 2 Nm (0. 12 kgfm) 7. Secure the connecting cable with the cord clamp. Fix the terminal cover, rear plate bushing and air inlet grille on the indoor unit. Piping and drain hose installation <Piping and Drain Hose Forming> * Since dewing results in a machine trouble, make sure to insulate both the connecting pipes. (Use polyethylene foam as insulating material. ) Rear right Left Bottom right Right Fig. 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. Changing drain hose For left connection, bottom-leftward connection and rear-leftward connection's piping, it is necessary to change the drain hose and drain cap. <How to remove the Drains Cap> Clip drain cap by needle-nose pliers, 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. Fig. 9-2-9 <How to install the Drain Hose> Firmly insert drain hose connecting part until hitting on a heat insulator.

SVM-05027 <How to fix the Drains Cap> <Left-hand connection with piping> 1) Insert hexagonal wrench (4 mm) in a center head. Bend the connecting pipe so that it is laid within 43 mm above the wall surface. If the connecting pipe is laid exceeding 43 mm above the wall surface, the indoor unit may unstably be set on the wall. When bending the connecting pipe, make sure to use a spring bender so 4 mm as not to crush the pipe. Bend the connection pipe within a radius of 30 mm (6. 35) 40 mm (9. 52). Fig. 9-2-11 2) Firmly insert drains cap. To connect the pipe after installation of the unit (figure) (To the forefront of flare) 270 mm No gap Do not apply lubricating oil (refrigerant machine oil) when inserting the drain cap. Application causes deterioration and drain leakage of the plug. 43 mm Liquid side Gas side 170 mm Outward form of indoor unit R 30 mm or less (6. 35) R 40 mm or less (9. 52) (Use polisin (polyethylene core) or the like for bending pipe. ) Insert a hexagon wrench (4 mm) Fig. 9-2-12 80 CAUTION Firmly insert the drain hose and drain cap; otherwise, water may leak. Use the handle of screwdriver, etc. Fig. 9-2-15 NOTE: If the pipe is bent incorrectly, the indoor unit may <In case of right or left piping> After scribing slits of the front panel with a knife or a unstably be set on the wall.
