Indoor Unit Installation
3) Pass the drain hose and refrigerant pipes through the wall hole, then
set the indoor unit on the mounting plate hooks by using the
markings at the top of the indoor unit as a guide.
4) Open the front panel, then open the service lid.
(Refer to preparation before installation.)
5) 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.)
6) Press the bottom frame of the indoor unit with both hands to
set it on the mounting plate hooks. Make sure the wires do
not catch on the edge of the indoor unit.
3-2. Left-side, left-back, or left-bottom piping
1) Attach the drain hose to the underside of the refrigerant pipes
with adhesive vinyl tape.
2) Be sure to connect the drain hose to the drain port in place of
a drain plug.
How to replace the drain plug and drain hose
• Replacing onto the left side
1) Remove the insulation fixing screw on the
right and remove the drain hose.
2) Remove the drain plug on the left side and
attach it to the right side.
3) Insert the drain hose and tighten with
included insulation fixing screw.
* (Forgetting to tighten this may cause
water leakages.)

How to set 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 and cause drain leakage
from the plug.
Insert a hexagonal wrench (4mm).
