Indoor Unit Installation

2. Boring a wall hole and installing wall embedded pipe.

• For walls containing metal frame or metal board, be sure to use a wall

embedded pipe and wall cover in the feed-through hole to prevent possible

heat, electrical shock, or fire.

• Be sure to caulk the gaps around the pipes with caulking material to prevent

water leakage.

1) Bore a feed-through hole of 65mm in the wall so it has a down slope

toward the outside.

2) Insert a wall pipe into the hole.

3) Insert a wall cover into wall pipe.

4) After completing refrigerant piping, wiring, and drain piping, caulk pipe

hole gap with putty.

3. Installing the indoor unit.

• In the case of bending or curing refrigerant pipes, keep the following

precautions in mind.

Abnormal sound may be generated if improper work is conducted.

1) Do not strongly press the refrigerant pipes onto the bottom frame.

2) Do not strongly press the refrigerant pipes on the front grille, either.

• Remove the pipe port cover as shown below.

1) Cut off the pipe port cover from inside the front grille using a copping

saw.

Apply the blade of the copping saw to the notch, and cut off the pipe

port cover along the uneven inner surface.

2) After cutting off the pipe port cover, perform filing. Remove the burrs

along the cut section using a half round needle file.

CAUTION

• If the pipe port cover is cut off using nippers, the front grille will be damaged. Please do not use nippers.

• Wear gloves during the pipe port cover removal.
