Specifications - Mitsubishi Electric MSZ-GS09NA Installation Manual

1-2. Selecting the Installation Location
Indoor Unit
• Where airflow is not blocked.
• Where cool (or warm) air spreads over the entire room.
• On a rigid wall to reduce the possibility of vibration.
• Where it is not exposed to direct sunlight. Do not expose
to direct sunlight also during the period following unpack-
ing to before use.
• Where it can be easily drained.
• At a distance 3 feet (1 m) or more away from a TV and
radio. Operation of the air conditioner may interfere with
radio or TV reception. An amplifier may be required for
the affected device.
• In a place as far away as possible from fluorescent and
incandescent lights (so the infrared remote control can
operate the air conditioner normally).
• Where the air filter can be removed and replaced easily.
• Where it is away from the other heat or steam source.
Note:
Install the indoor unit high on the wall where air can
distribute over the entire room.
Remote Controller
• Where it is convenient to operate and easily visible.
• Where children cannot easily touch it.
• Select a position about 4 feet (1.2 m) above the floor.
Check that signals from the remote controller from
that position are received by the indoor unit ('beep' or
'beep beep' receiving tone sounds). When the remote
controller holder is supplied, install it at a position from
which the indoor unit can receive signals.

1-3. Specifications

1-3-1. Power Supply and Indoor/Outdoor Wire Con-
nection
• Power should be taken from an exclusive branched circuit.
• Wiring work should be based on applicable technical standards.
• Wiring connections should be made following the diagram.
• Securely tighten screws.
Connecting wires and the ground wire
• Use solid conductor Min. AWG14 or stranded conductor
Min. AWG14.
• Use double insulated copper wire with 600 V insulation.
• Use copper supply wire.
* Follow local electrical codes.
Power supply cable and ground wire
• Use solid or stranded conductor Min. AWG14.
• Use copper supply wire.
* Follow local electrical codes.
Note:
When the indoor unit is powered from the outdoor unit, depend-
ing on local code, a disconnect switch needs to be installed to a
power supply circuit.
1-3-2. Refrigerant Pipes
• To prevent condensation, insulate the two refrigerant pipes.
Caution
Be sure to use the insulation of specified thickness (table on
the right). Excessive insulation may cause incorrect instal-
lation of the indoor unit, and too little insulation may cause
condensate to form.
• Refrigerant pipe bending radius must be 4 inches (100 mm) or
more.
• The unit has flared connections on both indoor and outdoor
sides.
• Remove the valve cover from the outdoor unit, then connect
the pipe.
• Refrigerant pipes are used to connect the indoor and outdoor
units.
• Be careful not to crush or over bend the pipe in pipe bending.
• Refrigerant adjustment... If pipe length exceeds 25 feet (7.5
m), additional refrigerant (R410A) charge is required.
(The outdoor unit is charged with refrigerant for pipe length up
to 25 feet [7.5 m])
• Please carefully consider the indoor unit location when piping
lengths are less than 16 feet (5 m) as there could be intermit-
tent noises during normal operation that would be noticeable
in very quiet environments.
Note:
In rooms where inverter type fluorescent lamps are used,
the signal from the wireless remote controller may not be
received.
Outdoor Unit
• Where it is not overly exposed to strong winds. If the
outdoor unit is exposed to a wind during defrosting, the
defrosting time will be longer.
• Where airflow is good and dustless.
• Where neighbours are not annoyed by operation sound
or hot (or cool) 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.
• If installing the unit in a location high above the ground,
be sure to secure the unit legs.
• Where it is at least 10 feet (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 recep-
tion 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 baffle boards.

Note:
• It is advisable to make a piping loop near outdoor unit
so as to reduce vibration.
• For increased efficiency, install the outdoor unit in a
location where continuous direct sunlight or excessive
water can be avoided as much as possible.
Note:
When operating the air conditioner in low outside tem-
perature, 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 and a baffle board
on the air outlet side.
Avoid the following places for installation where air
conditioner trouble is liable to occur.
• Where flammable gas could leak.
• Where there is an excessive amount of machine oil
in the air.
• 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 hot spring,
sewage, waste water.
• Where there is high-frequency or wireless equipment.
• Where there is emission of high levels of VOCs, includ-
ing phthalate compounds, formaldehyde, etc., which
may cause chemical cracking.
