Mitsubishi Electric NTXUKS06A112A Series Installation Manual page 3

This manual only describes the installation of indoor unit.
When installing the outdoor unit, refer to the installation manual of outdoor unit.
Depending on the installation area, install a Ground
I
Fault Interrupt (GFI) circuit breaker.
If the Ground Fault Interrupt (GFI) circuit breaker is not
installed, an electric shock could occur.
I Perform the drainage/piping work securely accord-
ing to the installation manual.
If there is defect in the drainage/piping work, water could
drop from the unit, soaking and damaging household
goods.
1-2. SELECTING THE INSTALLATION LOCATION
INDOOR UNIT
• Where airflow is not blocked.
• Where cool (or warm) air spreads over the entire room.
• Where it is not exposed to direct sunshine. Do not expose to direct sunshine also
during the period following unpacking to before use.
• Where easily drained.
• At a distance 3 ft. (1 m) or more away from your 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. In order
to make the infrared remote control operate the air conditioner normally. The heat
from the lights may cause deformation or the ultraviolet may cause deterioration.
• Where the air filter can be removed and replaced easily.
• Where it is away from the other heat or steam source.
1-3. SPECIFICATIONS
1-3-1. INDOOR/OUTDOOR WIRE CONNECTION
• 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 conductors only.
* Follow local electrical codes.
Note:
When the indoor unit is powered from the outdoor unit, depending
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.
Note:
Be sure to use the insulation of specified thickness (table on the right).
Excessive insulation may cause incorrect installation of the indoor
unit, and too little insulation may cause condensate to form.
• 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.
CAUTION
I Do not touch the air inlet or the aluminum fins of
the outdoor unit.
This could cause injury.
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.
REMOTE CONTROLLER
• Where it is easy to operate and easily visible.
• Where children cannot touch it.
• Select a position about 4 ft. (1.2 m) above the floor and check that signals from
the remote controller are surely received by the indoor unit from that position
('beep' or 'beep beep' receiving tone sounds). After that, attach remote controller
holder to a pillar or wall and install wireless remote controller.
Note:
In rooms where inverter type fluorescent lamps are used, the signal from the
wireless remote controller may not be received.
Note:
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 cook-
ing 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, including phthalate compounds,
formaldehyde, etc., which may cause chemical cracking.
• The appliance shall be stored so as to prevent mechanical damage from oc-
curring.

(Could lead to serious injury in particular environments when operated incorrectly.)
I Do not operate the air conditioner during interior
construction and finishing 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 condi-
tioner, resulting in water leakage or scattering of dew.
