DRILLING 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) Drill a feed-through hole of 2-9/16" (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.

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 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 installation tips.)
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.
Left-side, left-back, or left-bottom piping.
How to replace the drain plug and drain hose
• Removal method
1) Rotate to detach wire clip from hook 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 by rotating the
wire clip to hook.
Forgetting to tighten this may cause water
leakages.
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.
3) Shape the refrigerant pipe along the pipe path marking on
the mounting plate.
4) Pass drain hose and refrigerant pipes through the wall hole,
then set the indoor unit on mounting plate hooks, using the
markings at the top of indoor unit as a guide.
5) Pull in the inter-unit wiring.
6) Connect the inter-unit piping.

How to set drain plug
●
Do not apply lubricating oil (refrigerant
machine oil) when inserting.
Application causes deterioration and
drain leakage of the plug.
