4.1. Connecting pipes (Fig. 4-1)
• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100°C or more,
thickness of 12 mm or more).
• The indoor parts of the drain pipe should be wrapped with polyethylene foam
insulation materials (specifi c gravity of 0.03, thickness of 9 mm or more).
• Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening
fl are nut.
• Use two wrenches to tighten piping connections.
• Use refrigerant piping insulation provided to insulate indoor unit connections.
Insulate carefully.

• Be sure to insulate the connecting pipes and place them near the rear of the indoor unit so that they do not contact the front panel.
• Be careful not to crush the connecting pipes when bending them.
3) For left or left-rear piping (Fig. 4-5)
Bundle the connecting pipes and drain hose together, and then wrap them in felt
tape.
Make sure that the drain hose is not routed upward.
A
Felt tape
B
* Wrap the felt tape tightly around the pipes and hose starting near where the
pipes and hose are routed from the indoor unit. (The overlap width of the felt
tape should not be more than 1/2 of the tape width.)
Start wrapping the piping tape around the pipes and hose 10 mm inside the
C
indoor unit.
Fasten the end of the felt tape with a bandage stopper.
D
Cut and use the lower side panels on the left and right sides of the indoor unit as
shown.
Smooth the cut edges of the side panels so that they will not damage the insulation
coating. (Fig. 4-6)
Cut the lower side panels to match the height of the modelling.

5.1. Drainage piping work
• Be sure to route the drain piping slightly downward (1/100 or more) so that the
drain water fl ows easily.
• Do not route the drain piping as shown in the examples mark with an “X” in the
fi gure. (Fig. 5-1)
• If the drain hose is too short, refer to Fig. 5-2 to extend the length of the hose.
• If the indoor unit is installed in a high location such as a high-rise apartment,
strong winds may cause the drain water to fl ow back through the drain hose and
leak from the unit. If necessary, contact your nearest Mitsubishi Electric representative for the optional parts to prevent this problem.
• If the drain hose is routed indoors, be sure to wrap it in commercially-available
insulation.
• Do not connect the drain piping directly to a septic tank, sewage tank, etc., where
ammonia gases or hydrogen sulfi de are produced.
• If there is slack in the drain hose or the end of the drain hose is raised up, the
drain water may not fl ow smoothly and some drain water may collect in the hose.
This can lead to a strange sound (burbling) being produced during strong winds
or when a ventilation fan, etc., is used in a residence that is well-sealed. If necessary, contact your nearest Mitsubishi Electric representative for the optional parts
to prevent this problem.

• Make sure that the drain hose is not routed upward and that there are no waves
in the hose.
• Do not pull the drain hose, and then wrap tape around it.
• Route the piping so that it does not project past the rear of the indoor unit. (Refer
to the fi gure to the left.)

6.1. Embedding the indoor unit in a wall (Fig. 6-1)
• On the indoor unit and right and left space (100 mm or more) are the service
space.
• On a right side of the indoor unit, there is a hole for the room temperature sensor,
and do not close it, please.
• When installing a grating, use a grating with narrow upper and lower horizontal
bars so that the airfl ow from the upper and lower air outlets does not contact the
bars. If the horizontal bars will block the lower air outlet, use a stand, etc., to adjust the height of the indoor unit. If the upper or lower air outlet is blocked, the air
conditioner will not be able to cool or warm the room well.
• Use a grating with vertical bars, etc., that has at least 75% open area. If the grating has horizontal bars or if the open area is less than 75%, performance could
be reduced.
• When the indoor unit is embedded in a wall (built-in), the time it takes for the room
temperature to reach the set temperature will increase.

vane for the upper air outlet so that it only operates horizontally.
• If this setting is not performed, heat will build up in the wall and the room will not
be cooled or warmed properly.
• Remove the electrical part cover and pull out the control board.
• Set DIP switches 3-5 and 3-6 on the control board to ON.
• After setting the switches, reinstall the control board in its original position and
install the electrical part cover.
Caution:
To avoid damage to the control board due to static electricity, be sure to discharge the static buildup before handling it.
