• For walls containing metal frame or metal board, be sure to use a wall
embedded pipe and wall hole 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) Bore a feed-through hole of 65mm in the wall so it has a down slope
toward the outside.
2) Insert a wall embedded pipe into the hole.
3) Insert a wall hole cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk pipe
hole gap with putty.
1) Remove the screw cover and then the
service lid.
2) Pull out the inter-unit wire from the back of
the indoor unit to the front. It is easier to
pull out if bending up the wire edge in
advance.
3) To connect the inter-unit wire after hooking
the unit onto the
A
mounting plate,
connect the inter-unit wire as shown in the
figure.
Hang indoor unit’s
hook here.
Lift the indoor unit
slightly by placing it on
packing or other similar
materials.
When stripping the
ends of inter-unit
wire in advance,
bind right ends of
wires with insulation
tape.
