2 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.

· For RP100, 125 and 140, be sure to perform replacement
operation before test run.

· 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 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 refriger­ants. 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(PUHZ-RP35~RP140))

The refrigerant circuit with LEV(Linear Expansion Valve) and power receiver 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.

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.

outdoor unit’s terminal, i.e. Ato 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.

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 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”.)

8-4-2. 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”.)]

8-4-3. 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”.

A Stop C operation
B Cooling D Heating

Perform the following procedures to collect the refrigerant when moving the indoor unit or the outdoor unit.
1Turn on the power supply (circuit breaker).

wWhen power is supplied, make sure that “CENTRALLY CONTROLLED” is not displayed on the remote controller. If

“CENTRALLY CONTROLLED” is displayed, the refrigerant collecting (pump down) cannot be completed normally.

2After the liquid stop valve is closed, set the SWP switch on the control board of the outdoor unit to ON. The compressor

(outdoor unit) and ventilators (indoor and outdoor units) start operating and refrigerant collecting operation begins. LED1 and
LED2 on the control board of the outdoor unit are lit.
wSet the SWP switch (push-button type) to ON in order to perform refrigerant collecting operation only when the unit is

stopped. However, refrigerant collecting operation cannot be performed until compressor stops even if the unit is stopped.
Wait three minutes until compressor stops and set the SWP switch to ON again.

3Because the unit automatically stops in about two to three minutes after the refrigerant collecting operation (LED1 is not lit

and LED2 is lit), be sure to quickly close the gas stop valve.
wIn case the outdoor unit is stopped when LED1 is lit and LED2 is not lit, open the liquid stop valve completely, and then

repeat step 2 three minutes later.

wIf the refrigerant collecting operation has been completed normally (LED1 is not lit and LED2 is lit), the unit will remain

stopped until the power supply is turned off.

4Turn off the power supply (circuit breaker.)

2. Unit replacement operation

When reusing the existing pipes that carried R22 refrigerant for the RP100, RP125 and RP140 models, replacement
operation must be performed before performing a test run.

1If new pipes are used, these procedures are not necessary.
2If existing pipes that carried R22 refrigerant are used for the RP71 model, these procedures are not necessary.

(The replace-ment operation cannot be performed.)

3During replacement operation, “C5” is displayed on “A-Control Service Tool(PAC-SK52ST)”. (This is applied to only RP100,

RP125 and RP140 models.)

• Replacement operation procedures

1Turn on the power supply.
2Set DIP switch SW8-2 on the control board of the outdoor unit to ON to start replacement operation.

• The replacement operation is performed using the cooling system. Cool air will flow from the indoor unit during the replace­ment operation.

• During the replacement operation, is displayed on the remote controller and LED1 (green) and LED2 (red) on the
control board of the outdoor unit flash together.

3Replacement operation requires at least two hours to complete.

• After setting switch SW8-2 to ON, the unit automatically stops after two hours.

• Replacement operation can be performed repeatedly by setting switch SW8-2 from OFF to ON. Make sure to perform the

operation more than 2 hours. (If the operation is performed less than 2 hours, the existing pipes cannot be cleaned
enough and the unit may be damaged.)

• If replacement operation is performed over 2 hours, this action is recorded into nonvolatile memory of control board.

4Set switch SW8-2 to OFF. (Replacement operation is completed.)

wThe unit can be operated normally by remote controller even if SW8-2 remains ON.
wIf the indoor temperature is less than 15:, the compressor will operate intermittently but the unit is not faulty.

3. 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.

1Set the operation mode (cooling/heating) using SW4-2.
2Turn on SW4-1 to start test run with the operation mode set by SW4-2.
3Turn off SW4-1 to finish the test run.

• There may be a faint knocking sound around the machine room after power is supplied, but this is
no 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, but this is no problem with product because the check valve, itself, generates the
sound because pressure difference is small 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.)

<Error code display by self-diagnosis and actions to be taken for service (summary)>

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.)
