Indoor Unit Installation
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 fire.
• Be sure to caulk the gaps around the pipes with caulking material to prevent
water leakage.
1) Bore a feed-through hole of 2-9/16 inch (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 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.
5) Pass the inter-unit wiring 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 wiring
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.
