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.
· For RP60/71VHA3 and RP100/125/140, 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.
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 enters 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

Handle tools with care.
If dirt, dust or moisture enters 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 enters, 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 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.

(2) 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.
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 0.7mm 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 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 inch, 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-RP35/50/60/71/100/125/140)
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. It is completely eliminated by chargelss system. 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 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 burn out.
(3) Use 2-core x 1.25mm2 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.
Group
remote
controller
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 2 grounding spots on the shield wire, noise may enter into the shield wire because the ground wire
and shield wire form 1 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 1 circuit.
To avoid communication errors caused by noise, make sure to observe the single spot grounding method described in the
installation manual.

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”.)]

10-1. Refrigerant recovering (pump down)
Perform the following procedures to recover the refrigerant when moving the indoor unit or the outdoor unit.
1 Turn 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 recovering (pump down) cannot be completed normally.
2 After 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 fans (indoor and outdoor units) start operating and refrigerant recovering 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 recovering operation only when the unit is
stopped. However, refrigerant recovering operation cannot be performed until compressor stops even if the unit is stopped.
Wait 3 minutes until compressor stops and set the SWP switch to ON again.
3 Because the unit automatically stops in about 2 to 3 minutes after the refrigerant recovering 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 3 minutes later.
wIf the refrigerant recovering 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.
4 Turn off the power supply (circuit breaker.)
10-2. Unit replacement operation
When reusing the existing pipes that carried R22 refrigerant for the RP60/71VHA3 and RP100/125/140 models, replacement operation must be performed before performing a test run.
1 If new pipes are used, these procedures are not necessary.
2 If existing pipes that carried R22 refrigerant are used for the RP35-71VHA2 and RP35/50VHA3 model, these procedures
are not necessary.
(The replacement operation cannot be performed.)
3 During replacement operation, “C5” is displayed on “A-Control Service Tool (PAC-SK52ST)”. (This is applied to only RP60/
71VHA3 and RP100/125/140 models.)
Replacement operation procedures
1 Turn on the power supply.
2 Set 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 replace ment 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.
3 Replacement operation requires at least two hours to complete.
• After setting switch SW8-2 to ON, the unit automatically stops after 2 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.
4 Set 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.
TEST RUN
10-3. 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.
1 Set the operation mode (cooling/heating) using SW4-2.
2 Turn on SW4-1 to start 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, 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.)

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 “12. FUNCTION SETTING”.

Wait around 3 minutes to restart unit.
The air conditioner is in a state of being protected
by the microcomputer’s directive. Once the
compressor is stopped, the unit cannot be
restarted for 3 minutes. This control is also applied
when the unit is turned on and off by remote
controller.
Error code will be displayed if any protection
devices of the air conditioner are actuated.
What is error code?
Wait around 2 minutes.
An automatic startup test will be conducted for
2 minutes when power is supplied to the air
conditioner. “PLEASE WAIT” will be kept being
displayed while that time.
Refer to “SELF-DIAGNOSIS

Check if servicing is
required for the error.
“FILTER” is displayed on the
screen.
“STANDBY” is displayed on the
screen.
“DEFROST” is displayed on
the screen. (No air comes out of
the unit.)
This indicates that it is time to clean the air filters.
Clean the air filters. Press the FILTER button on
the remote controller twice to clear “FILTER” from
the display.
See the operation manual that came with the
product for how to clean the filters.
This is displayed when the unit starts HEAT
operation, when the thermostat puts the
compressor in operation mode, or when the
outdoor unit ends DEFROST operation and
returns to HEAT operation.
The display will automatically disappear around
10 minutes later.
While “STANDBY” is displayed on the remote
controller, the airflow amount will be restricted
because the indoor unit’s heat exchanger is not
fully heated up. In addition to that, the up/down
vane will be automatically set to horizontal blow
in order to prevent cold air from directly blowing
out to human body. The up/down vane will return
to the setting specified by the remote controller
when “STANDBY” is released.
The outdoor unit gets frosted when the outside
temperature is low and the humidity is high.
“DEFROST” indicates the DEFROST
operation is being performed to melt this frost. The
DEFROST operation ends in around 10 minutes
(at most 15 minutes).
During the DEFROST operation, the indoor unit’s
heat exchanger becomes cold, so the fan is
stopped. The up/down vane will be automatically
set to horizontal blow in order to prevent cold air
from directly blowing out to human body. The
display will turn into “STANDBY” when DEFROST
operation ends.
Display time of “FILTER”
depends on the model.
Long life filter: 2500 hrs.
Regular filter: 100 hrs.

Main body
<How to attach the coil>
Hold the lower part of the main body (shown as A) firmly so that
the main body does not move and attach the coil by inserting it
downward into the main body. Then securely attach the coil stopper to pipe B. (At this time, be careful that stress is not added to
lead wire and main body is not wound by lead wire.) If the stopper is not firmly attached to pipe B, coil may be detached from
the main body and that can cause defective operation of linear
expansion valve.
To prevent piping stress, be sure to attach the coil holding the
main body of linear expansion valve firmly. Otherwise pipe may
break.

(2) Check the following items and cautions for emergency operation
1
Make sure that there is no abnormality in outdoor unit other than the above abnormalities. (Emergency operation will
not be available when error code other than the above are indicated.)
2 For emergency operation, it is necessary to set the emergency operation switch (SWE) on indoor controller board. Refer
to the electrical wiring diagram of indoor unit for how to set the indoor unit.
3 During emergency operation, the air-conditioner will continuously be operated by supplying power and stopping it: It can
not be turned on or off by remote control, and temperature control is not possible.
4 Do not perform emergency heating operation for an extended period of time: If the outdoor unit starts defrosting during
this period, cold air will blow out from the indoor unit.
5
Do not perform emergency cooling operation for more than 10 hours: Neglecting this could result in freezing the heat
exchanger in indoor unit.
(3) Emergency operation procedure
Turn the main power supply off.
1
2 Turn on the emergency operation switch (SWE) on indoor controller board.
3 Set the shorting pins of emergency operation connector (CN31) on outdoor controller board to ON.
4 Use SW4-2 on outdoor controller board to set the operation mode (cooling or heating). (SW4-1 is not used.)

(5) Operation data during emergency operation
During emergency operation, no communication is performed with the indoor unit, so the data items needed for operation
are set to the following values:
Operation data
Intake temperature (TH1)
Indoor pipe temperature (TH2)
Indoor 2-phase pipe temperature (TH5)
Set temperature
Outdoor pipe temperature (TH3)
Outdoor discharge pipe temperature (TH4)
Outdoor 2-phase pipe temperature (TH6)
Outdoor ambient temperature (TH7)
Temperature difference code
(room temperature - set temperature) (∆Tj)
Discharge superheat (SHd)
Sub-cool (SC)
+1: If the thermistor temperature data is normal (not open/short), that data is loaded into the control as valid data.
When the unit enters emergency operation and TH values are mismatched, set the thermistors to open/short.
And the unit runs emergency operation with the values listed above.
+2: If one thermistor is set to open/short, the values for SHd/SC will be different from the list above.
[Example] When liquid temperature thermistor (TH3) has an open or short circuit.

w1 Forced defrost should be done as follows.
1Change the DIP SW1-1 on the outdoor controller board from OFF to ON.
2Forced defrost will start by the above operation 1 if all these conditions written below are satisfied.
• Heat mode setting
• 10 minutes have passed since compressor started operating or previous compulsory defrosting finished.
• Pipe temperature is less than or equal to 8:.
Forced defrost will finish if certain conditions are satisfied.
Forced defrost can be done if above conditions are satisfied when DIP SW1-1 is changed from OFF to ON.
After DIP SW1-1 is changed from OFF to ON, there is no problem if DIP SW1-1 is left ON or changed to OFF again. This
depends on the service conditions.
w2 ‘Power failure automatic recovery’ can be set by either remote controller or this DIP SW. If one of them is set to ON,
‘Auto recovery’ activates. Please set “Auto recovery” basically by remote controller because all units do not have DIP SW.
Please refer to the indoor unit installation manual.
w3 SW7-1,2 are used for demand control. SW7-1,2 are effective only at the demand control.
(Refer to next page : Special function (b))
w4 Please do not use SW7-3~6 usually. Trouble might be caused by the usage condition.

(a) Low-level sound priority mode (Local wiring)
Unit enters into Low-level sound priority mode by external signal input setting.
Inputting external signals to the outdoor unit decreases the outdoor unit operation sound 3 to 4 dB lower than that of usual.
Adding a commercial timer or on-off switch contactor setting to the CNDM connector which is optional contactor for demand
input located on the outdoor controller board enables to control compressor operation frequency.
W The performance depends on the load of conditioned outdoor temperature.
