*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/out-
door 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 resist-
ance will be insufficient.
*4 Use a copper pipe or a copper-alloy seamless pipe.
*5 Be careful not to crush or bend the pipe during pipe bending.
*6 Refrigerant pipe bending radius must be 100 mm or more.
*7 Insulation material : Heat resisting foam plastic 0.045 specific gravity
*8 Be sure to use the insulation of specified thickness. Excessive thick-
ness may cause incorrect installation of the indoor unit and insufficient
thickness may cause dew drippage.
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.
Port size of outdoor unit
MXZ-6D Liquid / Gas
A UNIT 6.35 (1/4) / 12.7 (1/2)
B - F UNIT 6.35 (1/4) / 9.52 (3/8)

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 opera-
tion 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. Op-
eration 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.

*9 If the outdoor unit is installed higher than the indoor unit, max. height
difference is reduced to 10 m.
*10 If pipe length exceeds 30 m, additional refrigerant (R410A) charge is
required. (No additional charge is required for pipe length less than
30 m.)
Additional refrigerant = A × (pipe length (m) - 30)
*11 The piping specification table does not provide a minimum line set
length. However, indoor units with connected piping length less than
3 m could produce intermittent noise during normal system operation in
very quiet environments. Please be aware of this important information
when installing and locating the indoor unit within the conditioned space.

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.
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot spring, sewage, waste
water.
• 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.
