3 SAFETY PRECAUTION
Use new refrigerant pipes.
Make sure that the inside and outside of refrigerant piping is clean and it has no contamination
such as sulfur hazardous for use, oxides, dirt,
shaving particles, etc.
In addition, use pipes with specified thickness.
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.
In case of using the existing pipes for R22, be careful with
the followings.
· Be sure to clean the pipes and make sure that the insides
of the pipes are clean.
· Change flare nut to the one provided with this product.
Use a newly flared pipe.
· Avoid using thin pipes.
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.

Tools for R410A
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
3-1. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
[1] Cautions for service
(1) Perform service after collecting the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) When performing service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder
· Check that cylinder for R410A on the market is syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

: Tools for other refrigerants can be used.
New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same
as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working
pressure of R410A is 1.6 time higher than that of R22, their sizes of flared sections and flare nuts are different.
1Thickness of pipes
Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness
shown below. (Never use pipes of 0.7mm or below.)
2Dimensions of flare cutting and flare nut
The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that,
R410A is a refrigerant, which has higher risk of leakage because of its working pressure higher than that of other refriger-
ants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A have been specified separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also
have partly been changed to increase intensity as shown below. Set copper pipe correctly referring to copper pipe flaring
dimensions for R410A below. For 1/2” and 5/8”, the dimension B changes.
Use torque wrench corresponding to each dimension.

CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT.
(Max.30m)
The refrigerant circuit with LEV(Linear Expansion Valve) and Accumlator always control the optimal refrigerant
level regardless of the length (30m max. and 5m min.) of piping. The additional refrigerant charging work during
installation often causes problems. Heretofore it is completely eliminated. This unique system improves the quality
and reliability of the work done. It also helps to speed up the installation time.

Good example 2 (Single spot grounding of shield wire)
(Points to notice)
(1) Outside the unit, transmission wires should stay away from electric wires in order to prevent electromagnetic noise from
making an influence on the signal communication. Place them at intervals of more than 5cm. Do not put them in the same
conduit tube.
(2) Terminal block (TB7) for transmission wires should never be connected to 220~240V power supply. If it is connected,
electronic parts on M-NET p.c. board may be burn out.
(3) Use 2-core x 1.25mm2shield wire (CVVS, CPEVS) for the transmission wire. Transmission signals may not be sent or
received normally if different types of transmission wires are put together in the same multi-conductor cable. Never do this
because this may cause a malfunction.
It would be ok if M-NET wire (non-polar, 2-cores) is arranged in addition to the wiring for A-control.
(4) Ground only one of any appliances through M-NET transmission wire (shield wire). Communication error may occur due to
the influence of electromagnetic noise.
“Ed” error will appear on the LED display of outdoor unit.
“0403” error will appear on the central-control remote controller.
If there are more than two grounding spots on the shield wire, noise may enter into the shield wire because the ground
wire and shield wire form one circuit and the electric potential difference occurs due to the impedance difference among
grounding spots. In case of single spot grounding, noise does not enter into the shield wire because the ground wire and
shield wire do not form one circuit.
To avoid communication errors caused by noise, make sure to observe the single spot grounding method described in the
installation manual.

shield wire for electric wires.
(Excluding the case connecting to system controller.)
(2) Connect the wire to the M-NET terminal block.Connect one core of the
transmission wire (non-polar) to Aterminal and the other to B. Peel the
shield wire, twist the shield part to a string and connect it to S terminal.
(3) In the system which several outdoor units are being connected, the terminal

9-4-1. M-NET address setting
In A-control models, M-NET address and refrigerant address should be set only for the outdoor unit. Similar to Free Combo
system, there is no need to set the address of outdoor unit and remote controller. To construct a central control system, the
setting of M-NET address should be conducted only upon the outdoor unit. The setting range should be 1 to 50 (the same as
that of the indoor unit in Free Combo system), and the address number should be consecutively set in a same group.
Address number can be set by using rotary switches
(SW11 for ones digit and SW12 for tens digit), which
is located on the M-NET board of outdoor unit.
(Factory setting: all addresses are set to “0”.)
9-4-2. Refrigerant address setting
In case of multiple grouping system (multiple refrigerant circuits in one group), indoor units should be connected by remote
controller wiring (TB5) and the refrigerant address needs to be set. Leave the refrigerant addresses to “00” if the group setting is not conducted. Set the refrigerant address by using DIP SW1-3 to -6 on the outdoor controller board. [Factory setting:
all switches are OFF. (All refrigerant addresses are “00”.)]
9-4-3. Regulations in address settings
In case of multiple grouping system, M-NET and refrigerant address settings should be done as explained in the above section. Set the lowest number in the group for the outdoor unit whose refrigerant address is “00” as its M-NET address.
w Refrigerant addresses can be overlapped if they are in the different group.
w In group B, M-NET address of the outdoor unit whose refrigerant address is “00” is not set to the minimum in the group. As
“3” is right for this situation, the setting is wrong. Taking group A as a good sample, set the minimum M-NET address in
the group for the outdoor unit whose refrigerant address is “00”.

Actions to be taken for service, which depends on whether or not the inferior phenomenon is reoccurring at service, are summarized in the table below. Check the contents below before investigating details.
11-2. CHECK POINT UNDER TEST RUN
(1) Before test run
• After installation of indoor and outdoor units, piping work and electric wiring work, re-check that there is no refrigerant leak-
age, loosened connections and incorrect polarity.
• Measure impedance between the ground and the power supply terminal block(L, N) on the outdoor unit by 500V Megger and
check that it is 1.0M" or over.
wDon’t use 500V Megger to indoor/outdoor connecting wire terminal block(S1, S2, S3) and remote controller terminal block
(1, 2). This may cause malfunction.
• Make sure that test run switch (SW4) is set to OFF before turning on power supply.
• Turn on power supply 12 hours before test run in order to protect compressor.
• For specific models which requires higher ceiling settings or auto-recovery feature from power failure, make proper changes
of settings referring to the description of “Selection of Functions through Remote Controller”.
Make sure to read operation manual before test run. (Especially items to secure safety.)

Heating mode: Check if warm air blows. (It takes a little
while until warm air blows.)
Check for correct motion of auto-vanes.
The outdoor unit features automatic capacity control to
provide optimum fan speeds. Therefore, the fan keeps
running at a low speed to meet the current outside air
condition unless it exceeds its available maximum power.
Then, in actuality, the fan may stop or run in the reverse
direction depending on the outside air, but this does not
mean malfunction.
Check if cool air blows and water is drained.
• In case of test run, the OFF timer will be activated, and the test run will automatically stop after two hours.
• The room temperature display section shows the pipe temperature of indoor units during the test run.
• Check that all the indoor units are running properly in case of simultaneous twin and triple operation. Malfunctions may not
be displayed regardless of incorrect wiring.
w1 After turning on the power supply, the system will go into startup mode, “PLEASE WAIT” will blink on the display section of
the room temperature, and lamp(green) of the remote controller will flash.
As to INDOOR BOARD LED, LED1 will be lit up, LED2 will either be lit up in case the address is 0 or turned off in case the
address is not 0. LED3 will blink.
As to OUTDOOR BOARD LED, LED1(green) and LED2(red) will light up. (After the startup mode of the system finishes,
LED2(red) will be turned off.)
In case OUTDOOR BOARD LED is digital display, — and — will be displayed alternately every second.

Test run [for wireless remote controller]
Measure an impedance between the power supply terminal block on
the outdoor unit and ground with a 500V Megger and check that it is
equal to or greater than 1.0M".
1 Turn on the main power to the unit.
2 Press the button twice continuously.
(Start this operation from the status of remote controller display
turned off.)
A and current operation mode are displayed.
3 Press the ( ) button to activate mode, then
check whether cool air is blown out from the unit.
4 Press the ( ) button to activate mode, then
check whether warm air is blown out from the unit.
5 Press the button and check whether strong air is blown out
from the unit.
6 Press the button and check whether the auto vane operates
properly.
7 Press the ON/OFF button to stop the test run.
Note:
• Point the remote controller towards the indoor unit receiver
while following steps
• It is not possible to run the in FAN, DRY or AUTO mode.

(2) Outdoor Unit
1) Check Items
• After installation of indoor and outdoor units, and tubing and electric wiring work, check that the unit is free from leaks of refrigerant, loosened
connections, and incorrect polarity.
• Check that there is no negative phase and open phase. (The F1 message for negative phase and the F2 message for open phase will flash
at digital indicator LED 1 on the outdoor substrate. If this happens, rewire correctly.)
• Measure the impedance between power terminals (Single phase: L,N,;;/ triple phase: L1,L2,L3,;;) and the ground with a 500V Megger and
check that it is 1.0MΩ or more. Do not operate the equipment if measurement is less than 1.0mΩ. *Never conduct this operation on the out-
door connection wiring terminals (S1,S2,S3) as this causes damage.
• When there is no error at the outdoor unit.
(If there is an error at the outdoor unit, it can be evaluated at LED 1 [digital display] of the outdoor substrate.)
• The stop valves are open both the liquid and gas sides.
After checking the above, execute the test run in accordance with the following.
2) Test run start and finish
• Operation from the indoor unit
Execute the test run using the installation manual for the indoor unit.
• Operation from the outdoor unit.
Execute settings for test run start, finish and operation mode (cooling, heating) using the DIP switch SW 4 on the outdoor substrate.
1 Set the operation mode (cooling, heating) using SW4-2.
2 Turn ON SW 4-1, The operation mode for SW 4-2 will be adhered to, and the test run will commence.
3 Turn OFF SW 4-1 to finish the test run.
• There may be a faint knocking noise emitted from the proximity of the fan during the test run. This is torque
fluctuation occurring due to control of fan revolutions. There is no problem with the product.
Note:
The SW 4-2 operation mode cannot be changed during the test run. (To change run mode, stop the equipment with SW 4-1, change
the operation mode, then restart test run with SW 4-1.)

11-3. HOW TO PROCEED "SELF-DIAGNOSIS"
11-3-1. When a Problem Occurs During Operation
If a problem occurs in the air conditioner, the indoor and outdoor units will stop,
and the problem is shown in the remote controller display.
[CHECK] and the refrigerant address are displayed on the temperature
display, and the error code and unit number are displayed alternately as
shown below.
1 If the outdoor unit is malfunctioning, the unit number will be "00".
2 In the case of group control, for which one remote controller controls
multiple refrigerant systems, the refrigerant address and error code of the
unit that first experienced trouble (i.e., the unit that transmitted the error
code) will be displayed.
3 To clear the error code, press the
button.
When using remote-/local-controller combined operation, cancel the error code after turning off remote operation. During
central control by a MELANS controller, cancel the error code by pressing the
button.
11-3-2. Self-Diagnosis During Maintenance or Service
