Do not use the existing refrigerant piping.
The old refrigerant and lubricant in the existing piping
contains a large amount of chlorine which may cause the
lubricant deterioration of the new unit.
Use “low residual oil piping”
If there is a large amount of residual oil (hydraulic oil, etc.)
inside the piping and joints, deterioration of the lubricant
will result.
Use ESTR , ETHER or HAB as the lubricant to
coat flares and flange connection parts.
If large amount of mineral oil enter, that can cause
deterioration of refrigerant oil etc.
Use liquid refrigerant to seal 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 refrigerant other than R407C.
If another refrigerant (R22, etc.) is used, the chlorine in the
refrigerant may cause the lubricant deterioration.
Use a vacuum pump with a reverse flow check valve.
The vacuum pump oil may flow back into the refrigerant
cycle and cause the lubricant deterioration.
Store the piping to be used during installation
indoors with keep both ends 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.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

SAFETY PRECAUTION
CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R407C
[1] Cautions for service
·After recovering the all refrigerant in the unit, proceed to working.
·Do not release refrigerant in the air.
·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.
[2] Refrigerant recharging
(1) Refrigerant recharging process
1Direct charging from the cylinder.
·R407C cylinder are available on the market has a syphon pipe.
·Leave the syphon pipe cylinder standing and recharge it.
(By liquid refrigerant)
(2) Recharge in refrigerant leakage case
·After recovering the all refrigerant in the unit, proceed to working.
·Do not release the refrigerant in the air.
·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.

Cautions for units utilizing refrigerant R410A
Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
Charge refrigerant from liquid phase of gas
cylinder.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
Do not use refrigerant other than R410A.
If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
Use a vacuum pump with a reverse flow check
valve.
Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil etc.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Keep the tools with care.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.

Note
1. At servicing for outdoor unit,always follow the wiring diagram of outdoor unit.
2. In case of using MA-Remote controller,please connect to TB15.
(Remote controller wire is non-polar.)
3. In case of using M-NET,please connect to TB5.(Transmission line is non-polar.)
4. Symbol[S] of TB5 is the shield wire connection.
5. Symbols used in wiring diagram above are, :terminal block, :connector.
6. The setting of the SW2 dip switches differs in the capacity.
For the detail,refer to the fig: w 1.
7. Please set the switch SW5 according to the power supply voltage.
Set SW5 to 240V side when the power supply is 230 and 240 volts.
When the power supply is 220 volts,set SW5 to 220V side.
8. Fasten terminal of the terminal board "TB5" equips lock system.
To remove the fasten terminal,pull it while pressing the protruding portion (locking level)
of the terminal. Connection of the fasten terminal,protruding portion shouid face upward.
• Linear expansion valve open/close through stepping motor after receiving the pulse signal from the indoor controller board.
• Valve opening can be changed in proportion to the number of pulse signal.
<Connection between the indoor controller board and the linear expansion valve>
Note : Since the number of the connector at the controller board side and the relay connector are different, follow the color of
❈ 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 lock and vibrate.
❈ 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
position.
When the valve move smoothly, there is no noise or vibration
occur from the linear expansion valve : however, when the pulse
number moves from E to A or when the valve is locked, more
noise can be hear than normal situation.
❈ Noise can be detected by placing the ear against the screw dri-
ver handle while putting the screw driver to the linear expansion
valve.
Trouble shooting
33
Symptom
Operation circuit failure of the micro
processor.
Linear expansion
valve mechanism is
locked.
Short or breakage of
the motor coil of the
linear expansion
valve.
Valve doesn't close
completely (thermistor leaking).
Wrong connection of
the connector or
contact failure.
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.
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.
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 150"I10%
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
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.
Check the color of lead wire and missing terminal of the connector.
Check points
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 temperature indicated in the remote
19
Countermeasures
Exchange the indoor controller board at drive circuit
failure.
Exchange the linear
expansion vale.
Exchange the linear
expansion valve.
If large amount of thermistor is leaked, exchange the
linear expansion valve.
Disconnect the connector
at the controller board,
then check the continuity.
