9 Operation Details
9.1.
BASIC FUNCTION
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,
automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the
microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature
shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that
judging the condition according to internal setting temperature and intake air temperature.
9.1.1.
Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes.
These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value
will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

12 Installation and Servicing Air Conditioner Using R410A
12.1. OUTLINE
12.1.1. About R410A Refrigerant
1. Converting air conditioners to R410A
Since it was declared in1974 that chlorofluorocarbons (CFC), hydro chlorofluorocarbons (HCFC) and other substances pose a
destructive danger to the ozone layer in the earth’s upper stratosphere (20 to 40 km above the earth), measures have been
taken around the world to prevent this destruction.
The R22 refrigerant which has conventionally been used in ACs is an HCFC refrigerant and, therefore, possesses this ozonedestroying potential. International regulations (the Montreal Protocol on Ozone-Damaging Substances) and the domestic laws
of various countries call for the early substitution of R22 by a refrigerant which will not harm the ozone layer.
• In ACs, the HFC refrigerant which has become the mainstream alternative is called R410A. Compared with R22, the
pressure of R410A is approximately 1.6 times as high at the same refrigerant temperature, but the energy efficiency is about
the same. Consisting of hydrogen (H), fluorine (F) and carbon (C), R410A is an HFC refrigerant. Another typical HFC
refrigerant is R407C. While the energy efficiency of R407C is somewhat inferior to that of R410A, it offers the advantage
of having pressure characteristics which are about the same as those of R22, and is used mainly in packaged ACs.
2. The characteristics of HFC (R410A) refrigerants
a. Chemical characteristics
The chemical characteristics of R410A are similar to those of R22 in that both are chemically stable, non-flammable
refrigerants with low toxicity.
However, just like R22, the specific gravity of R410A gas is heavier than that of air. Because of this, it can cause an oxygen
deficiency if it leaks into a closed room since it collects in the lower area of the room. It also generates toxic gas when it is
directly exposed to a flame, so it must be used in a well ventilated environment where it will not collect.

b. Compositional change (pseudo-azeotropic characteristics)
R410A is a pseudo-azeotropic mixture comprising the two components R32 and R125. Multi-component refrigerants with
these chemical characteristics exhibit little compositional change even from phase changes due to vaporization (or
condensation), which means that there is little change in the circulating refrigerant composition even when the refrigerant
leaks from the gaseous section of the piping.
Accordingly, R410A can be handled in almost the same manner as the single-component refrigerant R22. However, when
charging, because there is a slight change in composition between the gas phase and the liquid phase inside a cylinder or
other container, charging should basically begin with the liquid side.
c. Pressure characteristics
As seen in Table 2, the gas pressure of R410A is approximately 1.6 times as high as that of R22 at the same refrigerant
temperature, which means that special R410A tools and materials with high-pressure specifications must be used for all
refrigerant piping work and servicing.

d. R410A refrigerating machine oil
Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because
of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the
refrigerating machine oil to collect in the refrigerating cycle. For this reason, polyester and other synthetic oils which have
a high compatibility with R410A are used as refrigerating machine oil.
Because of the high hygroscopic property of synthetic oil, more care must be taken in its handling than was necessary with
conventional refrigerating machine oils. Also, these synthetic oils will degrade if mixed with mineral oil or alkylbenzene,
causing clogging in capillary tubes or compressor malfunction. Do not mix them under any circumstances.
12.1.2. Safety Measures When Installing/Servicing Refrigerant Piping
Cause the gas pressure of R410A is approximately 1.6 times as high as that of R22, a mistake in installation or servicing could
result in a major accident. It is essential that you use R410A tools and materials, and that you observe the following precautions
to ensure safety.
1. Do not use any refrigerant other than R410A in ACs that have been used with R410A.
2. If any refrigerant gas leaks while you are working, ventilate the room. Toxic gas may be generated if refrigerant gas is exposed
to a direct flame.
3. When installing or transferring an AC, do not allow any air or substance other than R410A to mix into the refrigeration cycle. If
it does, the pressure in the refrigeration cycle can become abnormally high, possibly causing an explosion and/or injury.
4. After finishing the installation, check to make sure there is no refrigerant gas leaking.
5. When installing or transferring an AC, follow the instructions in the installation instructions carefully. Incorrect installation can
result in an abnormal refrigeration cycle or water leakage, electric shock, fire, etc.
6. Do not perform any alterations on the AC unit under any circumstances. Have all repair work done by a specialist. Incorrect
repairs can result in a water leakage, electric shock, fire, etc.
12.2. TOOLS FOR INSTALLING/SERVICING REFRIGERANT PIPING
12.2.1. Necessary Tools
In order to prevent an R410A AC from mistakenly being charged with any other refrigerant, the diameter of the 3-way valve service
port on the outdoor unit has been changed. Also, to increase its ability to withstand pressure, the opposing dimensions have been
changed for the refrigerant pipe flaring size and flare nut. Accordingly, when installing or servicing refrigerant piping, you must have
both the R410A and ordinary tools listed below.

12.2.2. R410A Tools
1. Copper tube gauge for clearance adjustment
(used when flaring with the conventional flaring tool (clutch
type))
• This gauge makes it easy to set the clearance for the
copper tube to 1.0-1.5 mm from the clamp bar of the
flaring tool.
Fig. 1 Copper tube gauge for clearance adjustment
2. Flaring tool (clutch type)
• In the R410A flaring tool, the receiving hole for the
clamp bar is enlarged so the clearance from the clamp
bar can be set to 0-0.5 mm, and the spring inside the
tool is strengthened to increase the strength of the pipeexpanding torque. This flaring tools can also be used
with R22 piping, so we recommend that you select it if
you are buying a new flaring tool.

5. Charging hose
• The pressure resistance of the charging hose has been
raised to match the higher pressure of R410A. The hose
material has also been changed to suit HFC use, and
the size of the fitting has been changed to match the
manifold ports.

6. Vacuum pump adaptor
• When using a vacuum pump for R410A, it is necessary
to install an electromagnetic valve to prevent the
vacuum pump oil from flowing back into the charging
hose. The vacuum pump adaptor is installed for that
purpose. If the vacuum pump oil (mineral oil) becomes
mixed with R410A, it will damage the unit.
Fig. 5 Vacuum pump adaptor
7. Electric gas leak detector for HFC refrigerant
• The leak detector and halide torch that were used with
CFC and HCFC cannot be used with R410A (because
there is no chlorine in the refrigerant).
• The present R134a leak detector can be used, but the
detection sensitivity will be lower (setting the sensitivity
for R134a at 1, the level for R410A will drop to 0.6).
• For detecting small amounts of gas leakage, use the
electric gas leak detector for HFC refrigerant. (Detection
sensitivity with R410A is about 23 g/year).
Fig. 6 Electric gas leak detector for HFC refrigerant
52
CS-TE9DKE CU-TE9DKE / CS-TE12DKE CU-TE12DKE
8. Electronic scale for refrigerant charging
• Because of the high pressure and fast vaporizing speed
of R410A, the refrigerant cannot be held in a liquid
phase inside the charging cylinder when charging is
done using the charging cylinder method, causing
bubbles to form in the measurement scale glass and
making it difficult to see the reading. (Naturally, the
conventional R22 charging cylinder cannot be used
because of the differences in the pressure resistance,
scale gradation, connecting port size, etc.)
• The electronic scale has been strengthened by using a
structure in which the weight detector for the refrigerant
cylinder is held by four supports. It is also equipped with
two connection ports, one for R22 (7/16 UNF, 20
threads) and one for R410A (1/2 UNF, 20 threads), so
it can also be used for conventional refrigerant charging.
Fig. 7 Electronic scale for refrigerant charging
• There are two types of electronic scales, one for 10-kg
cylinders and one for 20-kg cylinders. (The 10-kg
cylinder is recommended.)
Refrigerant charging is done manually by opening and
closing the valve.
9. Refrigerant cylinders
• The R410A cylinders are labeled with the refrigerant
name, and the coating color of the cylinder protector is
pink, which is the color stipulated by ARI of the U.S.
• Cylinders equipped with a siphon tube are available to
allow the cylinder to stand upright for liquid refrigerant
charging.
Fig. 8 Refrigerant cylinders
10. Charging orifice and packing for refrigerant cylinders
• The charging orifice must match the size of the charging
hose fitting (1/2 UNF, 20 threads).
• The packing must also be made of an HFC-resistant
material.

12.3. REFRIGERANT PIPING WORK
12.3.1. Piping Materials
It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use
pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog
the expansion valves or capillaries.
Because the pressure of ACs using R410A is higher than those using R22, it is essential that you select materials that are
appropriate for these standards.
The thickness of the copper tubing used for R410A is shown in Table 10. Please be aware that tubing with a thickness of only 0.7
mm is also available on the market, but this should never be used.

12.3.2. Processing and Connecting Piping Materials
When working with refrigerant piping, the following points must
be carefully observed: no moisture od dust must be allowed to
enter the piping, and there must be no refrigerant leaks.
1. Procedure and precautions for flaring work
a. Cut the pipe
Use a pipe cutter, and cut slowly so the pipe will not be
deformed.
b. Remove burrs and clean shavings from the cut surface
If the shape of the pipe end is poor after removing burrs,
or if shavings adhere to the flared area, it may lead to
refrigerant leaks.
To prevent this, turn the cut surface downward and
remove burrs, then clean the surface, carefully.
Fig. 10 Flaring dimensions
c. Insert the flare nut (be sure to use the same nut that is
used on the AC unit)
d. Flaring
Check the clamp bar and the cleanliness of the copper
pipe.
Be sure to use the clamp bar to do the flaring with
accuracy. Use either an R410A flaring tool, or a
conventional flaring tool. Flaring tools come in different
sizes, so be sure to check the size before using. When
using a conventional flaring tool, use the copper pipe
gauge for clearance adjustment, etc., to ensure the
correct A dimension (see Fig. 10)

a. Check to make sure there is no scratches, dust, etc., on the flare and union.
b. Align the flared surface with the axial center of the union.
c. Use a torque wrench, and tighten to the specified torque. The tightening torque for R410A is the same as the conventional
torque value for R22. Be careful, because if the torque is too weak, it may lead to a gas leak. If it is too strong, it may split
the flare nut or make it impossible to remove the flare nut.

12.3.3. Storing and Managing Piping Materials
1. Types of piping and their storage
The following is a general classification of the refrigerant pipe materials used for ACs.
Because the gas pressure of R410A is approximately 1.6 times as high as that of R22, copper pipes with the thickness shown
in Table 10, and with minimal impurities must be used. Care must also be taken during storage to ensure that pipes are not
crushed, deformed, or scratched, and that no dust, moisture or other substance enters the pipe interior. When storing sheathed
copper pipes or plain copper pipes, seal the openings by pinching or taping them securely.
2. Makings and management
a. Sheathed copper pipes and copper-element pipes
When using these pipes, check to make sure that they are the stipulated thickness. For flare nuts, be sure to used the same
nut that is used on the AC unit.
b. Copper pipes
Use only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe is
exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily
distinguished from other piping materials, to prevent mistaken use.
3. Precautions during refrigerant piping work
Take the following precautions on-site when connecting pipes. (Keep in mind that the need to control the entry of moisture and
dust is even more important that in conventional piping).
a. Keep the open ends of all pipes sealed until connection with AC equipment is complete.
b. Take special care when doing piping work on rainy days. The entering of moisture will degrade the refrigerating machine oil,
and lead to malfunctions in the equipment.
c. Complete all pipe connections in as short a time as possible. If the pipe must be left standing for a long time after removing
the seal, it must be thoroughly purged with nitrogen, or dried with a vacuum pump.

12.4. INSTALLATION, TRANSFERRING, SERVICING
12.4.1. Inspecting Gas Leaks with a Vacuum Pump for New Installations (Using New
Refrigerant Piping)
1. From the viewpoint of protecting the global environment, please do not release refrigerant into the atmosphere.
a. Connect the projecting side (pin-pushing side) of the charging hose for the manifold gauge to the service port of the 3-way
valve. (1)
b. Fully open the handle Lo of the manifold gauge and run the vacuum pump. (2) (If the needle of the low-pressure gauge
instantly reaches vacuum, re-check step a).)
c. Continue the vacuum process for at least 15 minutes, then check to make sure the low-pressure gauge has reached -0.1
MPa (-76 cmHg). Once the vacuum process has finished, fully close the handle Lo of the manifold gauge and stop the
vacuum pump operation, then remove the charging hose that is connected to the vacuum pump adaptor. (Leave the unit in
that condition for 1-2 minutes, and make sure that the needle of the manifold gauge does not return.) (2) and (3)
d. Turn the valve stem of the 2-way valve 90° counter-clockwise to open it, then, after 10 seconds, close it and inspect for a
gas leak (4)
e. Remove the charging hose from the 3-way valve service port, then open both the 2-way valve and 3-way valve. (1) (4) (Turn
the valve stem in the counter-clockwise direction until it gently makes contact. Do not turn it forcefully).
f. Tighten the service port cap with a torque wrench (18 N.m (1.8 kgf.m)). (5) Then tighten the 2-way valve and 3-way valve
caps with a torque wrench (42 N.m (4.2 kgf.m)) or (55 N.m (5.5 kgf.m)). (6)
g. After attaching each of the caps, inspect for a gas leak around the cap area. (5) (6)
Precautions
• Be sure to read the instructions for the vacuum pump,
vacuum pump adaptor and manifold gauge prior to use,
and follow the instructions carefully.
• Make sure that the vacuum pump is filled with oil up to
the designated line on the oil gauge.
• The gas pressure back flow prevention valve on the
charging hose is generally open during use. When you
are removing the charging hose from the service port, it
will come off more easily if you close this valve.

12.4.2. Transferring (Using New Refrigerant Piping)
1. Removing the unit
a. Collecting the refrigerant into the outdoor unit by pumping down
The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the
temperature of the room is low.
• Check to make sure that the valve stems of the 2-way valve and 3-way valve have been opened by turning them counterclockwise. (Remove the valve stem caps and check to see that the valve stems are fully opened position. Always use
a hex wrench (with 4-mm opposing sides) to operate the valve stems.)
• Press the TEST RUN button on the indoor unit, and allow preliminary operation for 5-6 minutes. (TEST RUN mode)
• After stopping the operation, let the unit sit for about 3 minutes, then close the 2-way valve by turning the valve stem in
the clockwise direction.
• Press the TEST RUN button on the indoor unit again, and after 2-3 minutes of operation, turn the valve stem of the 3way valve quickly in the clockwise direction to close it, then stop the operation.
• Tighten the caps of the 2-way valve and 3-way valve to the stipulated torque.
• Remove the connection pipes (liquid side and gas side).
b. Removing the indoor and outdoor units
• Disconnect the pipes and connecting electric cables from between the indoor and outdoor units.
• Put capped flare nuts onto all of the pipe connections of the indoor and outdoor units, to make sure no dust or other
foreign matter enters.
• Remove the indoor and outdoor units.
2. Installing the unit
Install the unit using new refrigerant piping. Follow the instructions in section 4.1 to evacuate the pipes connecting the indoor
and outdoor units, and the pipes of the indoor unit, and check for gas leaks.
12.4.3. AC Units Replacement (Using Existing Refrigerant Piping)
When replacing an R410A AC unit with another R410A AC unit, you should re-flare the refrigerant piping. Even though the
replacement AC unit uses the R410A, problems occur when, for example, either the AC unit maker or the refrigerating machine oil
is different.
When replacing an R22 AC unit with an R410A AC unit, the following checks and cleaning procedures are necessary but are
difficult to do because of the chemical characteristics of the refrigerating machine oil (as described in items c) and d) of section
About R410A Refrigerant). In this case, you should use new refrigerant piping rather than the existing piping.
1. Piping check
Because of the different pressure characteristics of R22 and R410A, the design pressure for the equipment is 1.6 times
different. The wall thickness of the piping must comply with that shown in Table 10, but this is not easy to check. Also, even if
the thickness is correct, there may be flattened or bent portions midway through the piping due to sharp curves. Buried sections
of the piping also cannot be checked.
2. Pipe cleaning
A large quantity of refrigerating machine oil (mineral oil) adheres to existing pipes due to the refrigeration cycle circulation. If the
pipes are used just as they are for the R410A cycle, the capacity will be lowered due to the incompatibility of this oil with the
R410A, or irregularities may occur in the refrigeration cycle. For this reason, the piping must be thoroughly cleaned, but this is
difficult with the present technology.
12.4.4. Refrigerant Compatibility (Using R410A Refrigerant in R22 ACs and Vice Versa)
Do not operate an existing R22 AC with the new R410A refrigerant. Doing so would result in improper functioning of the equipment
or malfunction, and might lead to a major accident such as an explosion in the refrigeration cycle. Similarly, do not operate an
R410A AC with R22 refrigerant. The chemical reaction between the refrigerating machine oil used in R410A ACs and the chlorine
that is contained in R22 would cause the refrigerating machine oil to degrade and lead to malfunction.
12.4.5. Recharging Refrigerant During Servicing
When recharging is necessary, insert the specified amount of new refrigerant in accordance with the following procedure.
1. Connect the charging hose to the service port of the outdoor unit.
2. Connect the charging hose to the vacuum pump adaptor. At this time, fully open the 2-way valve and 3-way valve.
3. Fully open the handle Lo of the manifold gauge, turn on the power of the vacuum pump and continue the vacuum process for
at least one hour.
4. Confirm that the low pressure gauge shows a reading of -0.1 Mpa (-76 cmHg), then fully close the handle Lo, and turn off the
58
CS-TE9DKE CU-TE9DKE / CS-TE12DKE CU-TE12DKE
vacuum pump. Wait for 1-2 minutes, then check to make sure that the needle of the Low pressure gauge has not returned. See
Fig. 13 for the remaining steps of this procedure.
5. Set the refrigerant cylinder onto the electronic scale, then connect the hose the cylinder and to the connection port for the
electronic scale. (1)(2)
Precaution:
Be sure to set up the cylinder for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquid
without having to turn the cylinder around
6. Remove the charging hose of the manifold gauge from the vacuum pump adaptor, and connect it to the connection port of the
electronic scale. (2)(3)
7. Open the valve of the refrigerant cylinder, then open the charging valve slightly and close it. Next, press the check valve of the
manifold gauge and purge the air. (2)(4) (Watch the liquid refrigerant closely at this point.)
8. After adjusting the electronic scale to zero, open the charging valve, then open the valve Lo of the manifold gauge and charge
with the liquid refrigerant. (2)(5) (Be sure to read the operating instructions for the electronic scale.)
9. If you cannot charge the stipulated amount, operate the unit in the cooling mode while charging a little of the liquid at a time
(about 150 g/time as a guideline). If the charging amount is insufficient from one operation, wait about one minute, then use the
same procedure to do the liquid charging again.
Precaution:
Never use the gas side to allow a larger amount of liquid refrigerant to be charged while operating the unit.
10. Close the charging valve, and after charging the liquid refrigerant inside the charging hose, fully close the valve Lo of the
manifold gauge, and stop the operation of the unit. (2)(5)
11. Quickly remove the charging hose from the service port. (6) If you stop midway through, the refrigerant that is in the cycle will
be discharged.
12. After putting on the caps for the service port and operating valve, inspect around the caps for a gas leak. (6)(7)

12.4.6. Brazing
As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person.
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.
<Brazing Method for Preventing Oxidation>
1. Attach a reducing valve to the nitrogen gas cylinder.
2. Apply a seal onto the clearance between the piping and inserted pipe for the nitrogen gas in order to prevent the nitrogen gas
from flowing backward.
3. When the nitrogen gas is flowing, be sure to keep the piping end open.
4. Adjust the flow rate of nitrogen gas so that it is lower than 0.05 m3/h, or 0.02 MPa (0.2 kgf/cm2) by means of the reducing valve.
5. After taking the steps above, keep the nitrogen gas flowing until the piping cools down to a certain extent (i.e. temperature at
which pipes are touchable with finger).
6. Completely remove the flux after brazing.
Fig. 14 Prevention of Oxidation during Brazing
Cautions during brazing
1. General Cautions
a. The brazing strength should be high as required.
b. After operation, airtightness should be kept under pressurized condition.
c. During brazing do not allow component materials to become damaged due to overheating.
d. The refrigerant pipe work should not become blocked with scale or flux.
e. The brazed part should not restrict the flow in the refrigerant circuit.
f. No corrosion should occur from the brazed part.
2. Prevention of Overheating
Due to heating, the interior and exterior surfaces of treated metal may oxidize. Especially, when the interior of the refrigerant
circuit oxidizes due to overheating, scale occurs and stays in the circuit as dust, thus exerting a fatally adverse effect. So,
make brazing at adequate brazing temperature and with minimum of heating area.
3. Overheating Protection
In order to prevent components near the brazed part from overheating damage or quality deterioration due to flame or heat,
take adequate steps for protection such as (1) by shielding with a metal plate, (2) by using a wet cloth, and (3) by means
of heat absorbent.
4. Movement during Brazing
Eliminate all vibration during brazing to protect brazed joints from cracking and breakage.
5. Oxidation Preventative
In order to improve the brazing efficiency, various types of antioxidant are available on the market. However, the
constituents of these are widely varied, and some are anticipated to corrode the piping materials, or adversely affect HFC
refrigerant, lubricating oil, etc. Exercise care when using an oxidation preventive.
12.4.7. Servicing Tips
The drier must also be replaced whenever replacing the refrigerant cycle parts. Replacing the refrigerant cycle parts first
before replacing the drier. The drier is supplied in a vacuum pack. Perform brazing immediately after opening the vacuum
pack, and then start the vacuum within two hours. In addition, the drier also needs to be replaced when the refrigerant has
leaked completely. (Applicable for drier model only.)

13 Servicing Information
13.1. About Lead Solder (PbF)
DISTINCTION OF PbF P.C. BOARD
P.C. Boards (manufactured) using lead free solder will have a PbF stamp on the P.C. Board.
CAUTION
• Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70 °F (30 - 40 °C) higher.
Please use a high temperature solder iron and set it to 700 ± 20 °F (370 ± 10 °C)
• Pb free solder will tend to slash when heated too high (about 1100 °F/ 600°C). If you must use Pb solder, please completely
all of the Pb free solder on the pins or solder area before applying Pb solder. If this is not practical, be sure to heat the Pb
free solder until it melts, before applying Pb solder.
