[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.
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.)
Gravimeter
Unit
Make sure that the inside and outside of refrigerant piping is clean and it has no contaminants
such as sulfur, oxides, dirt, shaving particles, etc,
which are hazard to refrigerant cycle.
In addition, use pipes with specified thickness.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
Store the piping indoors, 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.
The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbenzene oil in a small amount.
If large amount of mineral oil enters, that 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.
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.
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.
Do not use refrigerant other than R410A.
If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
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.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Flare tool
Electronic refrigerant
charging scale
Vacuum pump adaptor
Size adjustment gauge
Gauge manifold
Torque wrench
Gas leak detector
Charge hose
Tools for R410A
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.
Use the specified refrigerant only.

Measure the existing pipe thickness and
check for damage.
The existing pipe thickness meets specifi ca-
tions and the pipes are not damaged.
Check if the existing air conditioner can operate.
After operating the cooling system for about 30
minutes, do a pump down work.
Disconnect the existing air conditioner from the
pipes.
Attach the new air conditioner
Test run
The existing pipes cannot be reused.
Use new pipes.
* If the existing air conditioner cannot operate, use a
refrigerant recovery device to collect the refrigerant.
* In case existing pipes were used for gas or oil
heat pump systems, be sure to clean the pipes for
ZRP100-140 models.
Use new pipes for ZRP35-71 models.
The existing pipe thickness does not meet
specifi cations or the pipes are damaged.

(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 times 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 has 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.

Notes: 1. Wiring size must comply with the applicable local and national code..
2. Power supply cables and Indoor/Outdoor unit connecting cables shall not be lighter than polychloroprene sheathed flexible cable.
3. Install an earth longer than other cables.
Warning:
In case of A-control wiring, there is high voltage 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-pole type.

8-4. 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 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 × 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.
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 2 earthing spots on the shield wire, noise may enter into the shield wire because the earth wire and
shield wire form 1 circuit and the electric potential difference occurs due to the impedance difference among earthing 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
1 circuit.
To avoid communication errors caused by noise, make sure to observe the single spot earthing method described in the
installation manual.

8-4-3. Regulations in address settings
In the 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.
* Refrigerant addresses can be overlapped if they are in the different group.
* 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”.
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 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 1st digit and SW12 for 2nd digit), which
is located on the M-NET board of outdoor unit.
(Initial setting: all addresses are set to “0”.)
8-4-2. Refrigerant address setting
In the case of multiple grouping system (multiple refrigerant circuits in 1 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”.)]

(1) Use 2-core × 1.25mm² 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 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 (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 earth
wire on the plate as shown on the right figure.

9-2. 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.)

9-1. REFRIGERANT COLLECTING (PUMP DOWN)
Perform the following procedures to collect the refrigerant when moving the indoor unit or the outdoor unit.
1 Supply power (circuit breaker).
* When power is supplied, make sure that “CENTRALLY CONTROLLED” is not displayed on the remote controller. If “CEN-
TRALLY CONTROLLED” is displayed, the refrigerant collecting (pump down) cannot be completed normally.
* Start-up of the indoor-outdoor communication takes about 3 minutes after the power (circuit breaker) is turned on. Start the
pump-down operation 3 to 4 minutes after the power (circuit breaker) is turned ON.
* In the case of multi-units control, before powering on, disconnect the wiring between the master indoor unit and the slave
indoor unit. For more details refer to the installation manual for the indoor unit.
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 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.
* Only set the SWP switch (push-button type) to ON if the unit is stopped. However, even if the unit is stopped and the SWP
switch is set to ON less than 3 minutes after the compressor stops, the refrigerant collecting operation cannot be performed.
Wait until compressor has been stopped for 3 minutes and then set the SWP switch to ON again.
3 Because the unit automatically stops in about 2 to 3 minutes when the refrigerant collecting operation is completed (LED1
off, LED2 lit), be sure to quickly close the gas stop valve. If LED1 is lit and LED2 is off and the outdoor unit is stopped,
refrigerant collection is not properly performed. Open the liquid stop valve completely, and then repeat step 2 after 3 minutes have passed.
* If the refrigerant collecting operation has been completed normally (LED1 off, LED2 lit), the unit will remain stopped until the
power supply is turned off.
4 Turn off the power supply (circuit breaker).
* Note that when the extension piping is very long with large refrigerant amount, it may not be possible to perform a pump-down
operation. When performing the pump-down operation, make sure that the low pressure is lowered to near 0 MPa (gauge).
Warning:
When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes. The compressor
may burst if air etc. get into it.

10-2. CHECK POINT UNDER TEST RUN
10-2-1. 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
(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 require higher ceiling settings or auto-recovery feature from power failure, make proper changes of
settings referring to the description of “11. FUNCTION SETTING”.
Make sure to read operation manual before test run. (Especially items to secure safety.)
