7. REFRIGERANT R410A  
This air conditioner adopts the new refrigerant HFC  
(R410A) which does not damage the ozone layer.  
(6) When an air conditioning system charged with a  
large volume of refrigerant is installed in a small  
room, it is necessary to exercise care so that,  
even when refrigerant leaks, its concentration  
does not exceed the marginal level.  
The working pressure of the new refrigerant R410A  
is 1.6 times higher than conventional refrigerant  
(R22).The refrigerating oil is also changed in  
accordance with change of refrigerant, so be careful  
that water, dust, and existing refrigerant or refrigerat-  
ing oil are not entered in the refrigerant cycle of the  
air conditioner using the new refrigerant during  
installation work or servicing time.  
If the refrigerant gas leakage occurs and its  
concentration exceeds the marginal level, an  
oxygen starvation accident may result.  
(7) Be sure to carry out installation or removal  
according to the installation manual.  
The next section describes the precautions for air  
conditioner using the new refrigerant. Conforming to  
contents of the next section together with the  
general cautions included in this manual, perform  
the correct and safe work.  
Improper installation may cause refrigeration  
trouble, water leakage, electric shock, fire, etc.  
(8) Unauthorized modifications to the air conditioner  
may be dangerous. If a breakdown occurs  
please call a qualified air conditioner technician  
or electrician.  
7-1. Safety During Installation/Servicing  
Improper repairs may result in water leakage,  
electric shock and fire, etc.  
As R410As pressure is about 1.6 times higher than  
that of R22, improper installation/servicing may  
cause a serious trouble. By using tools and materi-  
als exclusive for R410A, it is necessary to carry out  
installation/servicing safely while taking the following  
precautions into consideration.  
7-2. Refrigerant Piping Installation  
7-2-1. Piping Materials and Joints Used  
For the refrigerant piping installation, copper pipes  
and joints are mainly used. Copper pipes and joints  
suitable for the refrigerant must be chosen and  
installed. Furthermore, it is necessary to use clean  
copper pipes and joints whose interior surfaces are  
less affected by contaminants.  
(1) Never use refrigerant other than R410A in an air  
conditioner which is designed to operate with  
R410A.  
If other refrigerant than R410A is mixed, pres-  
sure in the refrigeration cycle becomes abnor-  
mally high, and it may cause personal injury, etc.  
by a rupture.  
(1) Copper Pipes  
It is necessary to use seamless copper pipes  
which are made of either copper or copper alloy  
and it is desirable that the amount of residual oil  
is less than 40 mg/10 m. Do not use copper  
pipes having a collapsed, deformed or discol-  
ored portion (especially on the interior surface).  
Otherwise, the expansion valve or capillary tube  
may become blocked with contaminants.  
(2) Confirm the used refrigerant name, and use  
tools and materials exclusive for the refrigerant  
R410A.  
The refrigerant name R410A is indicated on the  
visible place of the outdoor unit of the air condi-  
tioner using R410A as refrigerant.To prevent  
mischarging, the diameter of the service port  
differs from that of R22.  
As an air conditioner using R410A incurs  
pressure higher than when using R22, it is  
necessary to choose adequate materials.  
(3) If a refrigeration gas leakage occurs during  
installation/servicing, be sure to ventilate fully.  
Thicknesses of copper pipes used with R410A  
are as shown in Table 7-2-1. Never use copper  
pipes thinner than 0.8 mm even when it is  
available on the market.  
If the refrigerant gas comes into contact with fire,  
a poisonous gas may occur.  
(4) When installing or removing an air conditioner,  
do not allow air or moisture to remain in the  
refrigeration cycle. Otherwise, pressure in the  
refrigeration cycle may become abnormally high  
so that a rupture or personal injury may be  
caused.  
(5) After completion of installation work, check to  
make sure that there is no refrigeration gas  
leakage.  
If the refrigerant gas leaks into the room, coming  
into contact with fire in the fan-driven heater,  
space heater, etc., a poisonous gas may occur.

(2) Joints  
b) Socket Joints  
For copper pipes, flare joints or socket joints are  
used. Prior to use, be sure to remove all con-  
taminants.  
Socket joints are such that they are brazed  
for connections, and used mainly for thick  
pipings whose diameter is larger than 20 mm.  
Thicknesses of socket joints are as shown in  
Table 7-2-2.  
a) Flare Joints  
Flare joints used to connect the copper pipes  
cannot be used for pipings whose outer  
diameter exceeds 20 mm. In such a case,  
socket joints can be used.  
Sizes of flare pipe ends, flare joint ends and  
flare nuts are as shown in Tables 7-2-3 to 7-  
2-6 below.

(1) Flare Processing Procedures and Precautions  
a) Cutting the Pipe  
7-2-2. Processing of Piping Materials  
When performing the refrigerant piping installation,  
care should be taken to ensure that water or dust  
does not enter the pipe interior, that no other oil  
other than lubricating oils used in the installed air  
conditioner is used, and that refrigerant does not  
leak. When using lubricating oils in the piping  
processing, use such lubricating oils whose water  
content has been removed. When stored, be sure to  
seal the container with an airtight cap or any other  
cover.  
By means of a pipe cutter, slowly cut the pipe  
so that it is not deformed.  
b) Removing Burrs and Chips  
If the flared section has chips or burrs,  
refrigerant leakage may occur. Carefully  
remove all burrs and clean the cut surface  
before installation.  
24  
c) Insertion of Flare Nut  
d) Flare Processing  
Flare processing dimensions differ according  
to the type of flare tool. When using a con-  
ventional flare tool, be sure to secure dimen-  
sion Aby using a gauge for size adjustment.  
Make certain that a clamp bar and copper  
pipe have been cleaned.  
ØD  
By means of the clamp bar, perform the flare  
processing correctly.

a) Make sure that the flare and union portions  
do not have any scar or dust, etc.  
b) Correctly align the processed flare surface  
with the union axis.  
NOTE:  
c) Tighten the flare with designated torque by  
means of a torque wrench.The tightening  
torque for R410A is the same as that for  
conventional R22. Incidentally, when the  
torque is weak, the gas leakage may occur.  
When applying oil to the flare surface, be sure to use  
oil designated by the manufacturer. If any other oil is  
used, the lubricating oils may deteriorate and cause  
the compressor to burn out.

7-3. Tools  
7-3-1. Required Tools  
The service port diameter of packed valve of the outdoor unit in the air conditioner using R410A is changed to  
prevent mixing of other refrigerant.To reinforce the pressure-resisting strength, flare processing dimensions and  
opposite side dimension of flare nut (For Ø12.7 copper pipe) of the refrigerant piping are lengthened.  
The used refrigerating oil is changed, and mixing of oil may cause a trouble such as generation of sludge,  
clogging of capillary, etc. Accordingly, the tools to be used are classified into the following three types.  
(1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))  
(2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)  
(3) Tools commonly used for R410A and for conventional refrigerant (R22)  
The table below shows the tools exclusive for R410A and their interchangeability.

7-4. Recharging of Refrigerant  
When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the  
following steps.  
Recover the refrigerant, and check no refrigerant  
remains in the equipment.  
When the compound gauges pointer has indicated  
0.1 Mpa (76 cmHg), place the handle Low in the  
fully closed position, and turn off the vacuum pumps  
power switch.  
Connect the charge hose to packed valve service  
port at the outdoor units gas side.  
Keep the status as it is for 1 to 2 minutes, and ensure  
that the compound gauges pointer does not return.  
Connect the charge hose of the vacuum pump  
adapter.  
Set the refrigerant cylinder to the electronic balance,  
connect the connecting hose to the cylinder and the  
connecting port of the electronic balance, and charge  
liquid refrigerant.  
Open fully both packed valves at liquid and gas  
sides.  
Place the handle of the gauge manifold Low in the  
fully opened position, and turn on the vacuum pumps  
power switch. Then, evacuating the refrigerant in the  
cycle.  
(For refrigerant charging, see the figure below.)  
Never charge refrigerant exceeding the specified amount.  

ƒ
If the specified amount of refrigerant cannot be charged, charge refrigerant bit by bit in COOL mode.  
Do not carry out additional charging.  
When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in the  
refrigeration cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the  
specified amount is charged, and working pressure in the refrigeration cycle becomes abnormally high  
pressure, and may cause a rupture or personal injury.

Be sure to make setting so that liquid can be charged.  

When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down.  
It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant.  
Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the  
cylinder upside down if cylinder is not equipped with siphon.

R410A refrigerant is HFC mixed refrigerant.  
Therefore, if it is charged with gas, the composi-  
tion of the charged refrigerant changes and the  
characteristics of the equipment varies.

7-5. Brazing of Pipes  
Phosphor bronze brazing filler tends to react  
with sulfur and produce a fragile compound  
water solution, which may cause a gas  
leakage. Therefore, use any other type of  
brazing filler at a hot spring resort, etc., and  
coat the surface with a paint.  

7-5-1. Materials for Brazing  
(1) Silver brazing filler  
Silver brazing filler is an alloy mainly composed  
of silver and copper. It is used to join iron,  
copper or copper alloy, and is relatively expen-  
sive though it excels in solderability.  
When performing brazing again at time of  
servicing, use the same type of brazing filler.  
(2) Phosphor bronze brazing filler  
Phosphor bronze brazing filler is generally used  
to join copper or copper alloy.  
7-5-2. Flux  
(1) Reason why flux is necessary  
(3) Low temperature brazing filler  
By removing the oxide film and any foreign  
matter on the metal surface, it assists the flow  
of brazing filler.  
Low temperature brazing filler is generally called  
solder, and is an alloy of tin and lead. Since it is  
weak in adhesive strength, do not use it for  
refrigerant pipes.  
In the brazing process, it prevents the metal  
surface from being oxidized.  
By reducing the brazing filler's surface tension,  
the brazing filler adheres better to the treated  
metal.  
29  
(2) Characteristics required for flux  
7-5-3. Brazing  
Activated temperature of flux coincides with  
the brazing temperature.  
As brazing work requires sophisticated techniques,  
experiences based upon a theoretical knowledge, it  
must be performed by a person qualified.  
Due to a wide effective temperature range, flux  
is hard to carbonize.  
In order to prevent the oxide film from occurring in  
the pipe interior during brazing, it is effective to  
proceed with brazing while letting dry Nitrogen gas  
(N2) flow.  
It is easy to remove slag after brazing.  
The corrosive action to the treated metal and  
brazing filler is minimum.  
It excels in coating performance and is harm-  
less to the human body.  
Never use gas other than Nitrogen gas.  
(1) Brazing method to prevent oxidation  
As the flux works in a complicated manner as  
described above, it is necessary to select an  
adequate type of flux according to the type and  
shape of treated metal, type of brazing filler and  
brazing method, etc.  
Attach a reducing valve and a flow-meter to  
the Nitrogen gas cylinder.  

ƒ
Use a copper pipe to direct the piping mate-  
rial, and attach a flow-meter to the cylinder.  
(3) Types of flux  
Apply a seal onto the clearance between the  
piping material and inserted copper pipe for  
Nitrogen in order to prevent backflow of the  
Nitrogen gas.  
• Noncorrosive flux  
Generally, it is a compound of borax and boric  
acid.  
It is effective in case where the brazing tem-  
perature is higher than 800°C.  
When the Nitrogen gas is flowing, be sure to  
keep the piping end open.  
• Activated flux  
Adjust the flow rate of Nitrogen gas so that it  
is lower than 0.05 m³/Hr or 0.02 MPa (0.2kgf/  
cm²) by means of the reducing valve.  
Most of fluxes generally used for silver brazing  
are this type.  
It features an increased oxide film removing  
capability due to the addition of compounds  
such as potassium fluoride, potassium chloride  
and sodium fluoride to the borax-boric acid  
compound.  
After performing the steps above, keep the  
Nitrogen gas flowing until the pipe cools  
down to a certain extent (temperature at  
which pipes are touchable with hands).  
Remove the flux completely after brazing.

Therefore, use a flux which does not contain  
chlorine.

When adding water to the flux, use water

9. OUTDOOR CONTROL  
9-1. Outline of Main Controls  
1. Pulse ModulatingValve (PMV) control  
1) PMV is controlled with 50 to 500 pulses during operation, respectively.  
2) In cooling operation, PMV is controlled with the temperature difference between TS sensor and TC  
sensor.  
3) In heating operation, PMV is controlled with the temperature difference between TS sensor and TE  
sensor.  
4) For the temperature difference in items 2) and 3), 1 to 5K is aimed as the target in both cooling and  
heating operations.  
5) When the cycle excessively rose in both cooling and heating operations, PMV is controlled by TD sensor.  
The aimed value is usually 105°C for SM560 and 100°C for SM800, SM1100, SM1400 in both cooling  
and heating operations.  
REQUIREMENT  
A sensor trouble may cause a liquid back-flow or abnormal overheat resulting in excessive shortening of the  
compressor life. In a case of trouble on the compressor, be sure to check there is no error in the resistance  
value an the refrigerating cycle of each sensor after repair and then start the operation.  
2. Discharge temperature release control  
TD [˚C]  
1) This function controls the operation frequency, that  
is, lowers the operation frequency when the dis-  
charge temperature has not lower or the discharge

temperature has rapidly risen during PMV control. It  
subdivides the frequency control up to a unit of  
0.6Hz to stabilize the cycle.  
Frequency down  
2) When the discharge temperature is detected in an  
abnormal stop zone, the unit stops the compressor  
and restarts after 2 minutes 30 seconds.The error  
counter is cleared when it has continued the opera-  
tion for 10 minutes.

6. Coil heating control  
1) This control function heats the compressor by turning on the stopped compressor instead of a case  
heater. It purposes to prevent slackness of the refrigerant inside of the compressor.  
2) As usual, turn on power of the compressor for the specified time before a test run after installation,  
otherwise a trouble of the compressor may be caused. As same as a test run, it is recommended to turn  
on power of the compressor beforehand when starting operation after power of the compressor has been  
interrupted for a long time.  
3) A judgment for electricity is performed by TD and TO sensors. If TO sensor is defective, a backup control  
is automatically performed by TE sensor. For a case of defective TO sensor, judge it with the outdoor LED  
display.  
4) Coil heating is controlled by TD and TE sensor.  
5) For every model, the power is turned off when TD is 30°C or more.

NOTIFICATION  
It is not an abnormal phenomenon that electro-noise may be heard while heating the coil.  
7. Short intermittent operation preventive control  
The compressor may not stop for preventing the compressor for 3 to 10 minutes after start of the  
operation even if Thermo-OFF signal has been received from the indoor. This phenomenon is not  
abnormal. (Continuous operation time of the compressor differs according to the operating status.)  

If the equipment is stopped from the remote controller, the operation does not continue.  
8. High-pressure suppressionTE control (For SM800)  
This control suppresses that pressure becomes abnormally higher during cooling operation.  

ƒ
Stop the compressor under condition of TE 67°C, and count 1 on the error count.  
After 2 minutes 30 seconds passed, if TE < 67°C, the compressor restarts and the error count is  
cleared when the operation continues for 10 minutes.  
When TE 67°C is detected again within 10 minutes, 1 is added to the error count and restart is  
repeated.  
If the error counts 10 are recognized, it is determined as an error and restart is not performed.  
Error code P04is displayed.  
After restarting the compressor, continue controlling by using 70% to 90% of the control value of the  
current release control for minimum 30 minutes.  
9. Over-current preventive control  
This control function stops the compressor when over-current preventive circuit has detected an  

abnormal current.  
The compressor restarts with error count 1 after 2 minutes 30 seconds.  
ƒ
If the error counts 4 are recognized, it is determined as an error and restart is not performed.  
Error code H01, H02or P26is displayed.  
10. Current release value shift control  
1) For SM800, SM1100, SM1400  
This control function prevents troubles of the electron parts such as G-Tr of inverter of compressor  
drive system and troubles of the compressor during cooling operation.

11. Defrost control  
In heating operation, defrost operation is performed when TE sensor temperature satisfies any  

condition in A zone to D zone.  
The defrost operation is immediately finished if TE sensor temperature has become 12°C or more, or  
it also is finished when condition of 7°C TE < 12°C has continued for 1 minute. The defrost operation  
is also finished when defrost operation has continued for 10 minutes even if TE sensor temperature  
has become 7°C or lower.  
After defrost operation has finished, the compressor and the outdoor fan start heating operation after  
stopped for approx. 50 seconds.

12-3. How to Set an Address Number  
When connecting indoor units to the central control remote controller by using a network adapter, it is required  
to set up a network address No.  
The network address No. should be agreed with the line No. of the central control remote controller.  
When the unit was shipped from the factory, the network address has been set to 1.  
The following two methods to set the network address are provided.  
1. How to set from the remote controller at indoor unit side  
* This method is effective only when  
of set switch SW01 on the network adapter P.C. board is turned off.  
<Procedure> Set the network address while the unit stops.
