Installing interunit wiring

1) Remove the service lid from the front grill.
2) Take off the electric parts box service lid.
3) After attaching the mounting plate, connect the interunit wiring as shown
in the figure at right.

Laying piping, hoses, and wiring
• Lay the piping and drain hose according to the orientation of the piping
coming out of the unit, as shown below.
• Make sure the drain hose is sloped downward.
• Wrap the piping and the drain hose using insulating tape.
• Bind and then shape the pipes, hoses, and wires so that they can fit through
the piping through-hole.
• When cutting out the piping through-hole, cut out Part A using nippers along
the cut-out groove as shown in the figure at right.
Stopping the nippers part-way through Part A may cause it to break.
4-1. 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) Put all the pipes through the through-hole in the wall and attach the
indoor unit to the mounting plate.
(See p5 Installing and removing the indoor unit)
4) Connect the pipes.
5) Store any excess power cord behind the indoor unit.
6) Making sure not to pinch the interunit wiring and the power cord, push
on the bottom of the indoor unit with both hands and attach the tabs.
If the indoor unit won't attach to the mounting plate, fix the bottom
panel to the mounting plate with screws. (In one place on the left side
or the right side.)
4-2. Left-Side, Left-Back, or Left-Bottom Piping
1) Attach the drain hose to the underside of the refrigerant pipes with
adhesive vinyl tape.
2) Be sure to connect the drain hose to the drain port in place of a drain
plug.
1. Pull out the drain plug.
2. Pull out the drain hose and reattach it on the left side.
3. Reattach the drain plug on the right side.
3) Pull in the refrigerant piping and lay it so that it matches the
liquid and gas piping marked on the mounting plate.
4) Attach the indoor unit to the mounting plate.
5) Connect the pipes. If it is difficult to do, remove the front grill
first.
