Cautions for units utilizing refrigerant R410A
2-2. CAUTIONS RELATED TO NEW REFRIGERANT
Use new refrigerant pipes.
Store the piping indoors, and both ends of the
piping sealed until just before brazing.
(Leave elbow joints, etc. in their packaging.)
In case of using the existing pipes for R22, be careful with
the following:
· 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.
Handle tools with care.
If dirt, dust or moisture enters 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 enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If large amount of mineral oil enters, 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.
Make sure that the inside and outside of refrigerant piping is clean and it has no contaminants
such as sulfur, oxides, dirt, shaving particles, etc,
which are hazard to refrigerant cycle.
In addition, use pipes with specified thickness.
The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbenzene oil in a small amount.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.
Use the specified refrigerant only.

[3] Service tools
Use the below service tools as exclusive tools for R410A refrigerant.
[1] Cautions for service
(1) Perform service after recovering 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 a syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

Cautions for refrigerant piping work
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 times higher than that of R22, their sizes of flared sections and flare nuts are different.
1 Thickness 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 0.7 mm or below.)
2 Dimensions 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 its working pressure is higher than that of other refrigerants. Therefore, to enhance airtightness and strength, flare cutting dimension of copper pipe for R410A have been speci-
fied 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 strength as shown below. Set copper pipe correctly referring to copper pipe flaring
dimensions for R410A below. For 1/2 and 5/8 inch pipes, the dimension B changes. Use torque wrench corresponding to
each dimension.

8-4. M-NET WIRING METHOD
(Points to note)
(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 5 cm. Do not put them in the same
conduit tube.
(2) Terminal block (TB7) for transmission wires should never be connected to V power supply. If it is connected, electronic
parts on M-NET P.C. board may burn out.
(3) Use 2-core × 1.25 mm² shield 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) Earth 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 2 grounding spots on the shield wire, noise may enter into the shield wire because the earth wire
and shield wire form 1 circuit and the electric potential difference occurs due to the impedance difference among earthing
spots. In case of single spot grounding, noise does not enter into the shield wire because the earth wire and shield wire do
not form 1 circuit.
To avoid communication errors caused by noise, make sure to observe the single spot grounding method described in the
installation manual.

8-4-3. Regulations in address settings
In the 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.
* Refrigerant addresses can be overlapped if they are in the different group.
* 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”.
8-4-1. M-NET address setting
In A-control models, M-NET address and refrigerant address should be set only for the outdoor unit. Similar to CITY MULTI
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 CITY MULTI system), and the address number should be consecutively set in a same group.
Address number can be set by using rotary switches
(SW11 for 1s digit and SW12 for 10s digit), which
is located on the M-NET board of outdoor unit.
(Factory setting: all addresses are set to “0”.)
8-4-2. Refrigerant address setting
In the 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. [Initial
setting: all switches are OFF. (All refrigerant addresses are “00”.)]

(1) Use 2-core × 1.25 mm² 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 trans-
mission wire (no-polarity) to A terminal 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
(A, B, S) on M-NET terminal block should be individually wired to the other
outdoor unit’s terminal, i.e. A to A, B to B and S to S. In this case, choose one of those outdoor units and drive a screw
to fix an ground wire on the plate as shown on the right figure.

9-2. START AND FINISH OF TEST RUN
• Operation from the indoor unit
Execute the test run using the installation manual for the indoor unit.
• Operation from the outdoor unit
By using the DIP switch SW4 on the control board of outdoor unit, test run can be started and finished, and its operation
mode (cooling/heating) can be set up.
1 Set the operation mode (cooling/heating) using SW4-2.
2 Turn on SW4-1 to start the test run with the operation mode set by SW4-2.
3 Turn off SW4-1 to finish the test run.
•
There may be a faint knocking sound around the machine room after power is supplied. However,
this is not a problem with product because the linear expansion pipe is just moving to adjust opening pulse.
•
There may be a knocking sound around the machine room for several seconds after compressor
starts operating. However, this is not a problem with product because the check valve itself gener-
ates the sound due to small pressure difference in the refrigerant circuit.
Note:
The operation mode cannot be changed by SW4-2 during test run. (To change test run mode,
stop the unit by SW4-1, change the operation mode and restart the test run by SW4-1.)

9-1. REFRIGERANT COLLECTING (PUMP DOWN)
When relocating or disposing of the indoor/outdoor unit, pump down the system following the procedure below so that no refriger-
ant is released into the atmosphere.
1 Turn off the power supply (circuit breaker).
2 Connect the low-pressure valve on the gauge manifold to the charge plug (lowpressure side) on the outdoor unit.
3 Close the liquid stop valve completely.
4 Supply power (circuit breaker).
• When power is supplied, make sure that “CENTRALLY CONTROLLED” is not displayed on the remote controller. If “CEN-
TRALLY CONTROLLED” is displayed, the refrigerant collecting (pump down) cannot be completed normally.
• Start-up of the indoor-outdoor communication takes about 3 minutes after the power (circuit breaker) is turned on. Start the
pump-down operation 3 to 4 minutes after the power (circuit breaker) is turned on.
5 Perform the refrigerant collecting operation (cooling test run).
• Push the pump-down SWP switch (push-button type) on the control board of the outdoor unit. The compressor and ventilators
(indoor and outdoor units) start operating (refrigerant collecting operation begins). (LED1 and LED2 on the control board of
the outdoor unit are lit.)
• Only push the pump-down SWP switch if the unit is stopped. However, even if the unit is stopped and the pump-down SWP
switch is pushed less than 3 minutes after the compressor stops, the refrigerant collecting operation cannot be performed.
Wait until the compressor has been stopped for 3 minutes and then push the pump-down SWP switch again.
6 Fully close the stop valve on the gas pipe side of the outdoor unit when the pressure gauge on the gauge manifold shows 0.05
to 0 MPa [Gauge] (approx. 0.5 to 0 kgf/cm²) and quickly stop the air conditioner.
• Because the unit automatically stops in about 3 minutes when the refrigerant collecting operation is completed (LED1 off,
LED2 lit), be sure to quickly close the gas stop valve. However, if LED1 is lit, LED2 is off, and the unit is stopped, open the
liquid stop valve completely, close the valve completely after 3 minutes or more have passed, and then repeat step 5. (Open
the gas ball valve completely.)
• If the refrigerant collecting operation has been completed normally (LED1 off, LED2 lit), the unit will remain stopped until the
power supply is turned off.
• Note that when the extension piping is very long with a large refrigerant amount, it may not be possible to perform a pumpdown operation. In this case, use refrigerant recovery equipment to collect all of the refrigerant in the system.
7 Turn off the power supply (circuit breaker), remove the gauge manifold, and then disconnect the refrigerant pipes.
Warning:
When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.
• If the refrigerant pipes are disconnected while the compressor is operating and the stop valve (ball valve) is open, the
pressure in the refrigeration cycle could become extremely high if air is drawn in, causing the pipes to burst, personal
injury, etc.

10-2. CHECK POINT UNDER TEST RUN
10-2-1. 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 500 V Megger
and check that it is 1.0 M" or over.
*Do not 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.)
