Drilling A Wall Hole And Installing Wall Embedded Pipe
2.
• 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 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 Indoor Unit
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 cable tie wires upward for easier work in advance. (If the
inter-unit wire ends are to be stripped first, bundle the wire
lead 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 wire leads
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.
