Indoor Unit
Selection of Installation Place
Outdoor Unit
Place, robust not causing vibration, where the body can be supported sufficiently. Place, not affected by heat or steam generated in the vicinity, where inlet and outlet of the unit are not disturbed. Place, possible to drain easily, where piping can be connected with the outdoor unit. [. . . ] Insert the drain hose into the dent of heat insulation materials of indoor unit. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then connect them. Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape
Heat insulation material signal wire Piping
Lid for right piping Lid for under piping
Drain hose Lid for left piping Indoor/outdoor electric cable Change-for-fresh-air tube
Fix with adhesive tape
Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.
[Other direction piping]
Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according to the position of wall hole. Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation of connecting part specially.
Fixing the indoor unit body
Hang surely the unit body onto the upper notches of the mounting plate. In order to fix the body onto the mounting plate, hold up the body aslant from the underside and then put it down perpendicularly.
4. Connecting the indoor/outdoor Electric Cable Removing the wiring cover
Remove terminal cover at right bottom corner of indoor unit, then take off wiring cover by removing its screws.
When connecting the cable after installing the indoor unit
1. Insert from outside the room cable into left side of the wall hole, in which the pipe has already existed. Pull out the cable on the front side, and connect the cable making a loop.
When connecting the cable before installing the indoor unit
Insert the cable from the back side of the unit, then pull it out on the front side. Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws. Pull the cable slightly to make sure the cables have been properly inserted and tightened. After the cable connection, never fail to fasten the connected cable with the wiring cover.
