2. Boring 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 fi re.
Be sure to caulk the gaps around the pipes with caulking material to
prevent water leakage.
1) Bore 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
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.
1) Do not strongly press the refrigerant pipes onto the bottom frame.
2) 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 an adhesive vinyl tape.
2) Wrap the refrigerant pipes and drain hose together with an
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 wiring from the outdoor unit through the
feedthrough 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
wiring ends are to be stripped fi rst, 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.
