3-1. ALWAYS OBSERVE FOR SAFETY
Before obtaining access to termnal, all supply
ciucuits must disconnected.
3-2. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
Use new refrigerant pipes.
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.
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.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
Store the piping to be used indoors during
installation and both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
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.
Tools for R410A
Gauge manifold
Charge hose
Gas leak detector
Torque wrench
Flare tool
Size adjustment gauge
Vacuum pump adaptor
Electronic refrigerant
charging scale
Handle tools with care.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.
Ventilate the room if refrigerant leaks during
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.
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
[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.)

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 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 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 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.

9-4. 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 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 1.25mm
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 two earthing spots on the shield wire, noise may enter into the shield wire because the earth wire
and shield wire form one circuit and the electric potential difference occurs due to the impedance difference among earth-
ing spots. In case of single spot earthing, noise does not enter into the shield wire because the earth wire and shield wire
do not form one circuit.
To avoid communication errors caused by noise, make sure to observe the single spot earthing method described in the
installation manual.

(2) Connect the wire to the M-NET terminal block.Connect one core of the
transmission wire (non-polar) 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

part
(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.
9-4-1. 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 ones digit and SW12 for tens digit), which
is located on the M-NET board of outdoor unit.
(Initial 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. [Initial setting: all
switches are OFF. (All refrigerant addresses are “00”.)]
