Indoor Unit Installation
1) Cut off the pipe port cover from inside the front grille using a copping saw.
Apply the blade of the copping saw to the notch, and cut off the pipe port cover
along the uneven inner surface.
2) After cutting off the pipe port cover, perform filing. Remove the burrs along the
cut section using a half round needle file.
CAUTION
• If the pipe port cover is cut off using nippers, the front grille will be damaged. Please do not use nippers.
• Wear gloves during the pipe port cover removal.
3-1. 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 preparation before installation.)
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.
