Warning:
• Ask the dealer or an authorized technician to install the air conditioner.
• Do not alter the unit. It may cause fire, electric shock, injury or water
leakage.
• Install the unit at a place that can withstand its weight.
• Use the specified cables for wiring.
• Use only accessories authorized by Mitsubishi Electric and ask the dealer
or an authorized technician to install them.
• Do not touch the heat exchanger fins.
• Install the air conditioner according to this Installation Manual.
• Have all electric work done by a licensed electrician according to local
regulations.
• Do not use intermediate connection of the electric wires.
• If the air conditioner is installed in a small room, measures must be taken
to prevent the refrigerant concentration from exceeding the safety limit
even if the refrigerant should leak.
• The cut face punched parts may cause injury by cut, etc. The installers are
requested to wear protective equipment such as gloves, etc.
• When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it
with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal
high pressure in the refrigerant line, and may result in an explosion and
other hazards.
The use of any refrigerant other than that specified for the system will
cause mechanical failure or system malfunction or unit breakdown. In the
worst case, this could lead to a serious impediment to securing product
safety.

3.2.2. Drilling the piping hole (Fig. 3-3)
Use a core drill to make a hole of 75-80 mm, 2-61/64~3-5/32 inch diameter
in the wall in the piping direction, at the position shown in the diagram to
the left.
The hole should incline so that the outside opening is lower than the
inside opening.
Insert a sleeve (with a 75 mm, 2-61/64 inch diameter and purchased
locally) through the hole.
Note:
The purpose of the hole’s inclination is to promote drain flow.

3.2.3. Installing the wall mounting fixture
Since the indoor unit weighs near 21 kg, 46 lbs selection of the mounting
location requires thorough consideration. If the wall does not seem to be
strong enough, reinforce it with boards or beams before installation.
The mounting fixture must be secured at both ends and at the centre, if
possible. Never fix it at a single spot or in any nonsymetrical way.
(If possible, secure the fixture at all the positions marked with a bold
arrow.)
Warning:
If possible, secure the fixture at all positions indicated with a bold arrow.
Caution:
• The unit body must be mounted horizontally.
• Fastenattheholesmarkedwith▲asshownbythearrows.
