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 repair’s may result in water leakage,
electric shock and fire, etc.
As R410A’s 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.

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 A” by 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
Use either a flare tool for R410A or conven-
tional flare tool.

When it is strong, the flare nut may crack and
may be made non-removable. When choosing
the tightening torque, comply with values
designated by manufacturers.Table 7-2-7
shows reference values.
(2) Flare Connecting Procedures and Precautions
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 gauge’s pointer has indicated
–0.1 Mpa (–76 cmHg), place the handle Low in the
fully closed position, and turn off the vacuum pump’s
power switch.
Connect the charge hose to packed valve service
port at the outdoor unit’s gas side.
Keep the status as it is for 1 to 2 minutes, and ensure
that the compound gauge’s 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 pump’s
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-

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).

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

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

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.
