1.The supply voltage must be the same as the rated voltage of the air conditioner.

2.Prepare the power source for exclusive use with the air conditioner.

NOTE

•Wire type : More than H07RN-F or 245IEC66 (2,0mm² or more)

Wiring of the connecting cable can be carried out without removing of the front cabinet.

1.	Remove the front cabinet.
	Fully open the front cabinet. Disengage the
	support arm located in the upper center while
	pushing its handle leftwards, and then remove
	the panel toward you.
2.	Remove the terminal cover and cord clamp.

In case of rightward piping

•After scribing slits of the front cabinet and the rear panel by a knife or a marking-off pin, cut them by a pair of nippers or the like.

1.	Pass the pipe through the hole in the wall, and
	hook the indoor unit on the installation plate at
	the upper hooks.
2.	Swing the indoor unit to right and left to confirm
	that it is firmly hooked up on the installation plate.
3.	While pressing the indoor unit onto the wall,
	hook it at the lower part on the installation plate.
	Pull the indoor unit toward you to confirm that it
	is firmly hooked up on the installation plate.

CAUTION

• Use power specified above table.

• This appliance can be connected to the mains

3.	Insert the connecting cable (according to local
	cords) into pipe hole on the wall.
4.	Take out the connecting cable through the cable
	slot on the rear panel so that it is exploded by
	about 15 cm long in the front side.

in either of the following two ways.

(1) Connection to fixed wiring :

A switch or circuit breaker which

disconnects all poles and has a contact

separation of at least 3 mm must be

incorporate in the fixed wiring.

An approved circuit breaker or switches

must be used.

(2) Connection with power supply plug :

Attach power supply plug with power cord

5.	Insert the connecting cable fully into the
	terminal block and secure it by screw tightly.
6.	Tightening torque : 1,2 N•m (0,12 kgf•cm)
7.	Secure the connecting cable with the cord clamp.
8.	Fix the wiring cover, rear plate bushing and

Left-hand connection with piping

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 spring bender so as not to crush the pipe.

How to install the front cabinet on the indoor unit

• Install the front cabinet through the opposite order of “How to remove the front cabinet”.

When the panel is removed and mounted again, take the following actions:

After fastening the two screws, one each at the left and right of the air outlet be sure to push the upper center Q, right end R, left end S and the lower center T of the air outlet, and confirm that no gap is left between the front cabinet and the rear plate.

• If cooling (dry) operation is made without pushing

cable with facing tape tightly. In case of leftward piping and rear-leftward piping, bind the auxiliary pipes (two) only with facing tape.

•Carefully arrange pipes so that any pipe does not stick out of the rear plate of the indoor unit.

•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.

CAUTION

Arrange the drain pipe for proper drainage from the unit.

Improper drainage can result in dew-dropping.

This air conditioner has the structure designed to drain water collected from dew,

which forms on the back of theWall indoor unit, to the drain pan.

Therefore, do not store the power cord and other parts at a height above the drain
