- Inadequate connection and fastening may generate heat and
cause a fire.

• Prepare for typhoons and other strong winds and earthquakes
and install the unit at the specified place.

- Improper installation may cause the unit to topple and result in

injury.

• Always use an air cleaner, humidifier, electric heater, and other
accessories specified by Mitsubishi Electric.

- Ask an authorized technician to install the accessories. Improper

installation by the user may result in water leakage, electric shock,
or fire.

• Never repair the unit. If the air conditioner must be repaired,
consult the dealer.

- If the unit is repaired improperly, water leakage, electric shock, or

fire may result.

• Do not touch the heat exchanger fins.

- Improper handling may result in injury.

• If refrigerant gas leaks during installation work, ventilate the
room.

- If the refrigerant gas comes into contact with a flame, poisonous

gases will be released.

• Install the air conditioner according to this Installation Manual.

- If the unit is installed improperly, water leakage, electric shock, or

fire may result.

• Have all electric work done by a licensed electrician according
to “Electric Facility Engineering Standard” and “Interior Wire
Regulations”and the instructions given in this manual and al­ways use a special circuit.

- If the power source capacity is inadequate or electric work is per-

formed improperly, electric shock and fire may result.

• Securely install the cover of control box and the panel.

- If the cover and panel are not installed properly, dust or water

may enter the outdoor unit and fire or electric shock may result.

• When installing and moving the air conditioner to another site,
do not charge the it with a refrigerant different from the refrig­erant (

- If a different refrigerant or air is mixed with the original refrigerant,

the refrigerant cycle may malfunction and the unit may be dam­aged.

• 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.

- Consult the dealer regarding the appropriate measures to pre-

vent the safety limit from being exceeded. Should the refrigerant
leak and cause the safety limit to be exceeded, hazards due to
lack of oxygen in the room could result.

• When moving and reinstalling the air conditioner, consult the
dealer or an authorized technician.

- If the air conditioner is installed improperly, water leakage, elec-

tric shock, or fire may result.

• After completing installation work, make sure that refrigerant
gas is not leaking.

- If the refrigerant gas leaks and is exposed to a fan heater, stove,

oven, or other heat source, it may generate noxious gases.

• Do not reconstruct or change the settings of the protection
devices.

- If the pressure switch, thermal switch, or other protection device

is shorted and operated forcibly, or parts other than those specified
by Mitsubishi Electric are used, fire or explosion may result.

SAFETY PRECAUTIONS

2. Precautions for devices that use

Caution:

• Do not use the existing refrigerant piping.

- The old refrigerant and refrigerator oil in the existing piping con­tains a large amount of chlorine which may cause the refrigerator
oil of the new unit to deteriorate.

• Use refrigerant piping made of C1220 (Cu-DHP) phosphorus
deoxidized copper as specified in the *JIS H3300 “Copper and
copper alloy seamless pipes and tubes”. In addition, be sure
that the inner and outer surfaces of the pipes are clean and
free of hazardous sulphur, oxides, dust/dirt, shaving particles,
oils, moisture, or any other contaminant.

- Contaminants on the inside of the refrigerant piping may cause

the refrigerant residual oil to deteriorate.

*JIS: Japanese Industrial Standard

• Store the piping to be used during installation indoors and keep
both ends of the piping sealed until just before brazing. (Store
elbows and other joints in a plastic bag.)

- If dust, dirt, or water enters the refrigerant cycle, deterioration of

the oil and compressor trouble may result.

• Use ester oil, ether oil or alkylbenzene (small amount) as the
refrigerator oil to coat flares and flange connections.

- The refrigerator oil will degrade if it is mixed with a large amount of

mineral oil.

• Use liquid refrigerant to fill the system.

- If gas refrigerant is used to seal the system, the composition of

the refrigerant in the cylinder will change and performance may
drop.

• Do not use a refrig

- If another refrigerant (R22, etc.) is used, the chlorine in the refrig-

erant may cause the refrigerator oil to deteriorate.

• Use a vacuum pump with a reverse flow check valve.

- The vacuum pump oil may flow back into the refrigerant cycle and

cause the refrigerator oil to deteriorate.

• Do not use the following tools that are used with conventional
refrigerants.
(Gauge manifold, charge hose, gas leak detector, reverse flow
check valve, refrigerant charge base, vacuum gauge, refriger­ant recovery equipment)

- If the conventional refrigerant and refrigerator oil are mixed in the

• Do not use a charging cylinder.

- Using a charging cylinder may cause the refrigerant to deteriorate.

• Be especially careful when managing the tools.

- If dust, dirt, or water gets in the refrigerant cycle, the refrigerant

may deteriorate.

- Since R410A does not contain any chlorine, gas leak detectors
for conventional refrigerants will not react to it.

Warning:

Note the following when building a heater in the air
conditioning system.

- Leave enough space between units for proper ventilation so that
the indoor unit temperature does not exceed 40

˚C when

windless.

- Keep the heater clean, and take appropriate measures so that
the indoor unit does not suck in the dust particles that
accumulate on the heater.

- Use the optional heater cable (PAC-YU24HT) to perform an
interlocked operation with indoor units.

- Do not build a heater inside the indoor unit.

<Output pulse signal and the valve operation>

➁

Linear expansion valve operation

➂

Trouble shooting

Symptom

Check points

Operation circuit fail­ure of the micro
processor.

Disconnect the connector on the controller board, then con­nect LED for checking.

Pulse signal will be sent out for 10 seconds as soon as the
main switch is turn on. If there is LED with lights on or lights
off, it means the operation circuit is abnormal.

Countermeasures

Exchange the indoor con­troller board at drive circuit
failure.

Linear expansion
valve mechanism is
locked.

Valve doesn

´t close

completely (thermis­tor leaking).

Wrong connection of
the connector or
contact failure.

To check the linear expansion valve, operate the indoor unit in
fan mode and at the same time operate other indoor units in
cooling mode, then check the pipe temperature <liquid pipe

temperature> of the indoor unit by the out­door multi controller board operation moni­tor. During fan operation, linear expansion
valve is closed completely and if there are
some leaking, detecting temperature of the
thermistor will go lower. If the detected
temperature is much lower than the temper-

ature indicated in the remote controller, it
means the valve is not closed all the way. It is not necessary
to exchange the linear expansion valve, if the leakage is small
and not making any trouble.

Motor will idle and make ticking noise when motor is operated
while the linear expansion valve is locked. This ticking sound
is the sign of the abnormality.

Check the color of lead wire and missing terminal of the con­nector.

Exchange the linear
expansion vale.

Exchange the linear
expansion valve.

If large amount of refriger­ation is leaked, exchange
the linear expansion valve.

Disconnect the connector
at the controller board,
then check the continuity.

Measure the resistance between the each coil (red-white,
red-orange, brown-yellow, brown-blue) using a tester. It is
normal if the resistance is in the range of

Short or breakage of
the motor coil of the
linear expansion
valve.

Closing a valve : 1 → 2 → 3 → 4 → 1
Opening a valve : 4 → 3 → 2 → 1 → 4

The output pulse shifts in above order.

1. When linear expansion valve operation stops, all output phase
become OFF.

2. At phase interruption or when phase does not shift in order,
motor does not rotate smoothly and motor will locks and vibrates.

When the switch is turned on, 2200 pulse closing valve signal
will be send till it goes to A point in order to define the valve
