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 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.
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 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.
Gauge manifold Charge hose Gas leak detector
Torque wrench
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
Flare tool Size adjustment gauge Vacuum pump adaptor
Electronic refrigerant charging scale
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.
3
Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

·When performing replacement operation, make sure that DIP SW8-2 on outdoor unit controller board is set to ON. +Chemical compounds containing chlorine left in existing pipes are collected by replace filter.
The air conditioner automatically performs cooling operation through replace filter for about 2 hours.
Connecting a new air conditioner
Flaring work should be done so that flare meets the dimension for R410A. Use flare nut provided with indoor and outdoor unit.
When using gas piping of :19.05mm for HRP100, 125. Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.
This is to keep the pressure on pipes within permissible range.
Use different diameter joint or adjust the piping size by brazing. When using pipes larger than specified size for HRP71.
Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.
This is to prevent oil flow ratio from lowering due to the decrease in flowing refrigerant.
Use different diameter joint or adjust the piping size by brazing. When existing pipes are specified size.
The pipes can be reused referring to TECHNICAL DATA BOOK (OCS11).
Use different diameter joint or adjust the piping size by brazing.
* When using existing pipes for HRP71, 100, 125HA(2). Make sure that DIP SW8-2 on outdoor unit controller board is set to ON and perform replacement operation.

(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 0.7 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 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 has 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.

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 5 cm. 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 one circuit and the electric potential difference occurs due to the impedance difference among ground-
ing 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.

(1) Use 2-core × 1.25mm
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 A(M1) terminal and the other to B(M2). 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(M1), B(M2), S) on M-NET terminal block should be individually wired to the other

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”.)]

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).
w When 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.
Set the SWP switch (push-button type) to ON in order to perform refrigerant recovering operation only when the unit is
w
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.
w In 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.
w If 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.
4 Turn off the power supply (circuit breaker).
10-2. Unit replacement operation (except for PUHZ-HRP·HA2R1)
When reusing the existing pipes that carried R22 refrigerant for the HRP71, HRP100 and HRP125 models, replacement operation must be performed before performing a test run.
1 If new pipes are used, these procedures are not necessary. 2 During replacement operation, “C5” is displayed on “A-Control Service Tool (PAC-SK52ST)”.
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 replace­ment operation.
During the replacement operation, control board of the outdoor unit blink together.
3 Replacement operation requires at least 2 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.)
w The unit can be operated normally by remote controller even if SW8-2 remains ON. w If the indoor temperature is less than 15:, the compressor will operate intermittently but the unit is not faulty.
TEST RUN
is displayed on the remote controller and LED1 (green) and LED2 (red) on the
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.

Consider the temporary defects such as the work of protection devices in the refrigerant circuit including compressor, poor connection of wiring, noise and etc. Re-check the symptom, and check the installation environment, refrigerant amount, weather when the
trouble occurred, matters related to wiring and etc.
Reset error code logs and restart the unit after finishing service. There is no abnormality in electrical component, controller board, remote controller and etc.
Re-check the abnormal symptom.Conduct trouble shooting and ascertain the cause of the
trouble
according to “11-5. Troubleshooting
by inferior
phenomena”. Continue to operate unit for the time being if the cause is not ascertained. There is no abnormality concerning of parts such as electrical component, controller board, remote controller and etc.
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.
Do not use 500V Megger to indoor/outdoor connecting wire terminal block (S1, S2, S3) and remote controller terminal block
w
(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 power failure automatic recovery, make proper changes of set-
tings 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.)

Unit does not operate at all.
The operating display of remote
controller does not come on.
Unit cannot be restarted for a while after it has stopped.
Check if power is supplied to air conditioner. Nothing appears on the display unless power is supplied. 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 appears and blinks on the display of remote controller.
“PLEASE WAIT” is displayed
on the screen.
“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.)
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.
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.
Refer to “SELF-DIAGNOSIS ACTION TABLE”. Check if servicing is required for the error.
Display time of “FILTER” depends on the model. Long life filter: 2500 hrs. Regular filter: 100 hrs.

The fan speed does not match the setting of the remote controller during DRY operation.(No air comes out sometimes during DRY operation.)
The fan speed does not match
the setting of the remote controller in HEAT operation.
Check the set temperature of remote controller. The outdoor unit cannot be operated if the set temperature is not appropriate. The outdoor unit operates in the following modes. COOL: When the set temperature is lower than the room temperature. HEAT: When the set temperature is higher than the room temperature.
Check if filters are not dirty and clogged. If filters are clogged, the airflow amount will be reduced and the unit capacity will be lowered. See the instruction manual that came with the product for how to clean the filters.
Check there is enough space around the air conditioner. If there are any obstacles in the air intake or air outlet of indoor/outdoor units, they block the airflow direction so that the unit capacity will be lowered.
This is not a malfunction. This is the sound which is heard when the flow of refrigerant in the air conditioner is switched.
This is not a malfunction. This is the sound which is heard when internal parts of units expand or contract when the temperature changes.
This is not a malfunction. This is the sound which is heard when the outdoor unit starts operating.
This is not a malfunction. This is the sound which is heard when the fan of the outdoor unit is controlling the airflow amount in order to keep the optimum operating condition.
This is not a malfunction. This is the sound which is heard when the refrigerant is flowing inside the indoor unit.
This is not a malfunction.
During the DRY operation, the blower’s ON/OFF is controlled by the microcomputer to prevent overcooling and to ensure efficient dehumidification. The fan speed cannot be set by the remote controller during DRY operation.
This is not a malfunction.
1) When the HEAT operation starts, to prevent the unit from blowing cold air, the fan speed is gradually increased from zero to the set speed, in proportion to the temperature rise of the discharged air.
2) When the room temperature reaches the set temperature and the outdoor unit stops, the unit starts the LOW AIR operation.
3) During the HEAT operation, the DEFROST operation is performed to defrost the outdoor unit. During the DEFROST operation, the blower is stopped to prevent cold air coming out of the indoor unit.
The up/down vane will be automatically set to horizontal blow in these cases listed up on the left (1)~3)). After a while, the up/down vane will be automatically moved according to the setting of the remote controller.

· When linear expansion valve operation stops, all output phase become OFF.
· When the switch is turned on, 700 pulse closing valve signal will be sent till it goes to
A point in order to define the valve position.
(The pulse signal is being sent for about 20 seconds.)
When the valve moves smoothly, there is no sound or vibration
occurring from the linear expansion valve : however, when the pulse number moves from B to A or when the valve is locked, sound can be heard.
No sound is heard when the pulse number moves from
B to A in
case coil is burnt out or motor is locked by open-phase.

(3) How to attach and detach the coil of linear expansion valve
<Composition> Linear expansion valve is separable into the main body and the coil as shown in the diagram below.
Stopper
Coil
Lead wire
<How to detach the coil>
Hold the lower part of the main body (shown as A) firmly so that the main body does not move and detach the coil by pulling it upward. Be sure to detach the coil holding main body firmly. Otherwise pipes can bend due to pressure.
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 main body. (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 main body, 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.

Be sure to attach the stopper.

11-8. EMERGENCY OPERATION
(1) When the error codes shown below are displayed on outdoor unit or microcomputer for wired remote controller or indoor
unit has a failure, but no other problems are found, emergency operation will be available by setting the emergency opera­tion switch (SWE) on indoor controller board to ON and short-circuiting the connector (CN31) on outdoor controller board.
LWhen following abnormalities occur, emergency operation will be available.

(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.

• Heat mode setting
• 10 minutes have passed since compressor started operating or previous forced defrost 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, 4 ,6 usually. Trouble might be caused by the usage condition. w5 Only for HRP100VHA2(R1) [For HRP71VHA/71VHA2(R1)/100VHA model, breaker capacity should be 32A regardless of

Special function
(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.
NOTE: When the Dip SW 9-1 on the control board of the outdoor unit is ON, set Dip SW9-1 to OFF.
