dealer and install the ventilation system, otherwise lack of oxygen
can occur, which can cause serious accident.

When installing in small rooms, take prevention measures not v
to exceed the density limit of refrigerant in the event of leakage,
referred by the formula (accordance with ISO5149).

If the density of refrigerant exceeds the limit, please consult the
dealer and install the ventilation system, otherwise lack of oxygen
can occur, which can cause serious accident.

After completed installation, check that no refrigerant leaks v
from the system.

If refrigerant leaks into the room and comes into contact with an
oven or other hot surface, poisonous gas is produced.

Use the prescribed pipes, flare nuts and tools for R410A.v

Using existing parts (for R22 or R407C) can cause the unit failure
and serious accidents due to burst of the refrigerant circuit.

Tighten the flare nut by torque wrench with specified method.v

If the flare nut were tightened with excess torque, this may cause
burst and refrigerant leakage after a long period.

Do not open the operation valves for liquid line and gas line v
until completed refrigerant piping work, air tightness test and
evacuation.

If the compressor is operated in state of opening operation valves
before completed connection of refrigerant piping work, air can be
sucked into refrigerant circuit, which can cause burst or personal
injury due to anomalously high pressure in the refrigerant.

The electrical installation must be carried out by the qualifiedv
electrician in accordance with “the norm for electrical work” and
“national wiring regulation”, and the system must be connected
to the dedicated circuit.

Power supply with insufficient capacity and incorrect function done
by improper work can cause electric shocks and fire.

Be sure to shut off the power before starting electrical work.v

Failure to shut off the power can cause electric shocks, unit failure or
incorrect function of equipment.

Be sure to fix up the service panels.v

Incorrect fixing can cause electric shocks or fire due to intrusion of
dust or water.

Be sure to switch off the power supply in the event of v
installation, inspection or servicing.

If the power supply is not shut off, there is a risk of electric shocks,
unit failure or personal injury due to the unexpected start of fan.

Stop the compressor before removing the pipe after shutting v
the service valve on pump down work.

If the pipe is removed when the compressor is in operation with the
service valve open, air would be mixed in the refrigeration circuit and
it could cause explosion and injuries due to abnormal high pressure
in the cooling cycle.

Only use prescribed option parts. The installation must be v
carried out by the qualified installer.

If you install the system by yourself, it can cause serious trouble
such as w

ater leaks, electric shocks, fire.

Be sure to wear pr

otective goggles and gloves while at work.v

Earth leakage breaker must be installed.v

If the earth leakage breaker is not installed, it can cause electric
shocks.

Do not put the drainage pipe directly into drainage channelsv
where poisonous gases such as sulphide gas can occur.

Poisonous gases will flow into the room through drainage pipe and
seriously affect the user’s health and safety. This can also cause the
corrosion of the indoor unit and a resultant unit failure or refrigerant
leak.

Ensure that no air enters in the refrigerant circuit when the unit v
is installed and removed.

If air enters in the refrigerant circuit, the pressure in the refrigerant
circuit becomes too high, which can cause burst and personal injury.

Do not bundling, winding or processing for the power cord. Or,v
do not deforming the power plug due to tread it.

This may cause fire or heating.

Do not processing, splice the power cord, or share a socketv
with other power plugs.

This may cause fire or electric shock due to defecting contact,
defecting insulation and over-current etc.

Do not vent R410A into the atmosphere : R410A is a fluorinatedv
greenhouse gas, covered by the Kyoto Protocol with Global
Warming Potential (GWP)=1975.

Do not run the unit with removed panels or protections.v

Touching rotating equipments, hot surfaces or high voltage parts can
cause personal injury due to entrapment, burn or electric shocks.

Insulation of connecting portion

① Cover the connection portion of the refrigerant piping with the

pipe cover and seal them.

If neglecting to do so, moisture occurs onthe piping and water will
drip out.

② Finishing and fixing

ⓐ Tie up the piping with wrapping tape, and shape it so that it conforms

to which the pipe is attached.

ⓑ Fix them with clamps as right figure.

Vinyl tape

To cover the connecting portion with insulation
materials, cut u pper porti on and then sea l it
with insulation materials.

Cover the exterior portion with cov­ering tape and shape the piping so it
will match the contours of the route
that the piping to take. Also fix the
wiring and pipings to the wall with
clamps.

How to relocate or dispose of the unit

•

In order to protect the environment,be sureto pumpdown (recovery
of refrigerant).

•

Pump down is the method of recovering refrigerant from the indoor
unit to the outdoor unit when the pipes are removed from the unit.

<How to pump down>

① Connect charge hose to check joint.
② Liquid side : Close the liquid valve with hexagon wrench key.

Gas side : Fully open the gas valve.
Carry out cooling operation. (If indoor temperature is low, operate

forced cooling operation.)

③ After low pressuregauge become 0.01MPa, close thegas valve then

stop cooling operation.

• Forced cooling operation

Turn on a power supply again after a while after turn off a power supply.
Then press continually the ON/OFF button 5 seconds or more.

Connect operation valve, charge hose, manifold valve ②
and vacuum pump as is illustrated right.
Open manifold valve handle Lo to its full width, and ③
perform vacuum or evacuation.
Continue the vacuum or evacuation operation for
15 minutes or more and check to see that the vacuum
gauge reads -0.1MPa.
After completing vacuum operation, close the Lo handle ④
and stop operation of the vacuum pump.
After completing vacuum operation, fully open ⑤
operation valve (Both gas and liquid sides) with
hexagon headed wrench.
Check for possible leakage of gas in the connection ⑥
parts of both indoor and outdoor.

Since the system uses check joints differing in diameter •
from those found on the conventional models, a charge
hose (for R22) presently in use is not applicable. Please
use one designed specifically for R410A.
Please use an anti-reverse flow type vacuum pump adapter •
so as to prevent vacuum pump oil from running back into
the system. Oil running back into an air-conditioning
system may cause the refrigerant cycle to break down.

(1) Cautions

(a) If you are disassembling and checking an air conditioner, be sure to turn off the power before beginning. When work

-

ing on indoor units, let the unit sit for about 1 minute after turning off the power before you begin work. When work

-

ing on an outdoor unit, there may be an electrical charge applied to the main circuit (electrolytic condenser), so begin

work only after discharging this electrical charge (to DC 10 V or lower).

(b) When taking out printed circuit boards, be sure to do so without exerting force on the circuit boards or package

components.

(c) When disconnecting and connecting connectors, take hold of the connector housing and do not pull on the lead wires.

(2) Items to check before troubleshooting

(a) Have you thoroughly investigated the details of the trouble which the customer is complaining about?

(b) Is the air conditioner running? Is it displaying any self-diagnosis information?

(c) Is a power supply with the correct voltage connected?

(d) Are the control lines connecting the indoor and outdoor units wired correctly and connected securely?

(e) Is the outdoor unit’s service valve open?

(3) Troubleshooting procedure (If the air conditioner does not run at all)

If the air conditioner does not run at all, diagnose the trouble using the following troubleshooting procedure. If the air

conditioner is running but breaks down, proceed to troubleshooting step (4).

the aps open manually,

then close again when
the power is turned on?

Is the r e a re c e pt i o n
sound emitted from the
unit when it is operated
by the remote control?

Replace the indoor PCB and
perform an operation check.

Make sure the correct volt­age is connected, then per­form an operation check.

Is the current fuse on the in­door unit PCB blown?

Proceed to the indoor PCB
check.

Proceed to the wireless remote
control troubleshooting proce­dure.

procedure.

(2) After making sure the DC fan motor and indoor PCB are

normal, connect the co nnectors and confirm that the fan
motor is turning.

(If power is turned on while one or the other is broken down,

it could cause the other to break down also.)

* Disc onne ct the fan mo to r

connec tor, then investigate
the DC fan motor and indoor
PCB separately.

(9) How to make sure of wireless remote control

(C) Power transistor inspection procedure

[Use a tester with a needle indicator for the inspection. (Do not use a digital tester. Check in the AC 300 volt range.)]
(1) If there is a self-diagnosis display, inspect the compressor system (burns, wiring mistakes, etc.) If no problems are found, check the

output of the power transistor.

(2) Output inspection procedure

Disconnect the terminals for the compresseor.
If an output such as the one shown in the figure on the below can be measured, the power transistor and the circuit board for the
outdoor unit are normal.

(Example)
