Mitsubishi Electric MXZ-4F83VF Installation Manual page 4

CAUTION
I Install an earth leakage breaker depending on the installation place.
If an earth leakage breaker is not installed, it could cause electric shock.
I Perform the drainage/piping work securely according to the installation
manual.
If there is defect in the drainage/piping work, water could drop from the unit, soak-
ing and damaging household goods.
I Do not touch the air inlet or the aluminum fins of the outdoor unit.
This could cause injury.

*1 Connect to the power switch which has a gap of 3 mm or more when open to
interrupt the source power phase. (When the power switch is shut off, it must
interrupt all phases.)
*2 Use wires in conformity with design 60245 IEC 57. Use the indoor/outdoor
connecting wire in conformity with the wire specifications specified in the
installation manual of the indoor unit.
*3 Never use pipes with thickness less than specified. The pressure resistance
will be insufficient.
*4 Use a copper pipe or a copper-alloy seamless pipe.
1-3. SELECTING OPTIONAL DIFFERENT-DIAMETER JOINTS
If the diameter of connection pipe does not match the port size of outdoor unit, use optional different-diameter joints according to the following table.

1-4. SELECTING THE INSTALLATION LOCATION
• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where rain or direct sunshine can be avoided as much as possible.
• Where neighbours are not annoyed by operation sound or hot air.
• Where rigid wall or support is available to prevent the increase of operation
sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit, be sure to secure the unit legs.
• Where it is at least 3 m away from the antenna of TV set or radio. Operation
of the air conditioner may interfere with radio or TV reception in areas where
reception is weak. An amplifier may be required for the affected device.
• Install the unit horizontally.
• Please install it in an area not affected by snowfall or blowing snow. In areas
with heavy snow, please install a canopy, a pedestal and/or some baffle boards.
Note:
It is advisable to make a piping loop near outdoor unit so as to reduce vibration
transmitted from there.

I Do not install the outdoor unit where small animals may live.
If small animals enter and touch the electric parts inside the unit, it could cause a
malfunction, smoke emission, or fire. Also, advise user to keep the area around
the unit clean.
I Do not operate the air conditioner during interior construction and finish-
ing work, or while waxing the floor.
Before operating the air conditioner, ventilate the room well after such work is
performed. Otherwise, it may cause volatile elements to adhere inside the air
conditioner, resulting in water leakage or scattering of dew.

*8 Be sure to use the insulation of specified thickness. Excessive thickness may
cause incorrect installation of the indoor unit and insufficient thickness may
cause dew drippage.
*9 At least 2 indoor units must be connected when using indoor unit with capacity
lower than 25 class.

Refer to the installation manual of indoor unit for the diameter of connection pipe of indoor unit.
Note:
When operating the air conditioner in low outside temperature, be sure to
follow the instructions described below.
• Never install the outdoor unit in a place where its air inlet/outlet side may
be exposed directly to wind.
• To prevent exposure to wind, install the outdoor unit with its air inlet side
facing the wall.
• To prevent exposure to wind, it is recommended to install a baffle board
on the air outlet side of the outdoor unit.
Avoid the following places for installation where air conditioner trouble is
liable to occur.
• Where flammable gas could leak.
• Where there is much machine oil.
• Where oil is splashed or where the area is filled with oily smoke (such as
cooking areas and factories, in which the properties of plastic could be
changed and damaged).
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where there is high-frequency or wireless equipment.
• Where there is emission of high levels of VOCs, including phthalate
compounds, formaldehyde, etc., which may cause chemical cracking.
• The appliance shall be stored so as to prevent mechanical damage from
occurring.
