1) Switch around the drain plug and drain hose.
2) Attach the drain hose to the underside of the refrigerant
pipes with adhesive vinyl tape.
3) Shape the refrigerant pipes along the pipe path marking
on the mounting plate.
4) Pass the drain hose and refrigerant pipes through the
wall hole, then position the indoor unit on the mounting
plate hooks, using the markings at the top of the indoor
unit as a guide.
5) Open the front panel, then open the service lid. (Refer to
“Service lid” on page 4.)
6) Pass the inter-unit wire from the outdoor unit through the
feed-through wall hole and then through the back of the
indoor unit. Pull them through the front side. Bend the ends of
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.)
7) Connect the refrigerant pipes.
8) In case of pulling the drain hose through the back of the
indoor unit, wrap the refrigerant pipes and drain hose
together with insulation tape as shown in the figure.
9) Press the bottom frame of the indoor unit with both hands
until it is firmly caught by the mounting plate hooks. Make
sure that the wires do not catch on the edge of the indoor
unit.

Drain plug
No gap
Do not apply lubricating oil
(refrigerant oil) to the drain
plug when inserting it.
The application of lubrication
oil to the drain plug will
deteriorate the plug to cause
drain leakage from the plug.
Insert a hexagonal
wrench (3/16 inch (4mm)).
2) Pull out
