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 ESTER , 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 charge 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.

CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT.
PU/PUH-P25, P35, P50, P60 : max 20m
PU/PUH-P71, P100, P125, P140 : max 30m
The refrigerant circuit with LEV(Linear Expansion Valve) and a large accumulator always control the optimal refrigerant
level regardless of the length (20/30m 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.

Warning:
In case of A-control wiring, there is high v oltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between power line
and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power is
energized. If isolator should be used between indoor unit and outdoor unit, please use 3-poles type.

Be sure to connect the indoor-outdoor connecting cables directly to the units (no intermediate
connections).
Intermediate connections can lead to communication errors if water enters the cables and causes
insufficient insulation to ground or a poor electrical contact at the intermediate connection point.
(If an intermediate connection is necessary, be sure to take measures to prevent water from entering
the cables.)

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
(A, B, S) on M-NET terminal block should be individually wired to the other

8-3-1. 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”.)
8-3-2. 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”.)]
8-3-3. 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”.

Present and past error codes are logged and displayed on the wired remote controller and control board of outdoor unit.
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.
10-2. 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 Merger and
check that it is 1.0M" or over.
wDon’t use 500V Merger 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 twelve 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.)
