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.
• Do not strongly press the refrigerant pipes onto the bottom frame.
• Do not strongly press the refrigerant pipes on the front grille, either.
3-1. Right-side, right-back, or right-bottom piping
1) Attach the drain hose to the underside of the refrigerant pipes with
adhesive vinyl tape.
2) Wrap the refrigerant pipes and drain hose together with insulation tape.
3) Pass the drain hose and refrigerant pipes through the wall hole, then
position the indoor unit on the
markings at the top of the indoor unit as a guide.
4) Open the front panel, then open the service lid (Refer to "Indoor Unit
Installation" on page 4).
5) Pass the inter-unit wire from the outdoor unit through the feed-through
wall hole and pass to the front of indoor unit from the back. Then pull
them at front side. Bend the ends of cable tie wires upward for easier
work in advance. (If the inter-unit wire ends are to be stripped first,
bundle wire ends with adhesive tape.)
6) Press the bottom frame of the indoor unit with both hands until it is firmly
caught by the
catch on the edge of the indoor unit.
3-2. Left-side, left-back, or left-bottom piping
1) Switch around the drain plug and drain hose.
