CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE
LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure
of R410A refrigerant is approx. 1.6 times of refrigerant R22. Accompanied with the adoption of the new refrigerant, the
refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former
refrigerant, or refrigeration machine oil does not enter into the new type refrigerant R410A air conditioner circuit.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main unit and
installation tools are different from those used for the conventional refrigerant units.
Accordingly, special tools are required for the new refrigerant (R410A) units. For connecting pipes, use new and clean piping
materials with high pressure fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the
existing piping because there are some problems with pressure fittings and possible impurities in existing piping.

CAUTION
• Exposure of unit to water or other moisture before installation may result in an electrical short.
Do not store in a wet basement or expose to rain or water.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level
of the unit or where noise or discharged air might disturb neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
For Reference: RAS-∗∗ PAVP-E model
If a heating operation would be continuously performed for a long time under the condition that the outdoor
temperature is 0°C or lower, drainage of defrosted water may be difficult due to freezing of the bottom plate,
resulting in a trouble of the cabinet or fan.
It is recommended to procure an antifreeze heater locally for a safe installation of the air conditioner.
For details, contact the dealer.
(RAS-∗∗ PAVP-ND model has a heater on the bottom plate of the outdoor unit.)

2REFRIGERANT R410A
This air conditioner adopts the new refrigerant HFC (R410A) which does not damage the ozone layer.
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 refrigerating oil are not entered in the refrigerant cycle of the air conditioner using the new
refrigerant during installation work or servicing time.
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.
2-1. Safety During Installation/Servicing
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 materials exclusive for R410A, it is necessary to carry out installation/servicing
safely while taking the following precautions into consideration.
• Never use refrigerant other than R410A in an air conditioner which is designed to operate with R410A.
If other refrigerant than R410A is mixed, pressure in the refrigeration cycle becomes abnormally high, and it may
cause personal injury, etc. by a rupture.
• 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 conditioner using
R410A as refrigerant. To prevent mischarging, the diameter of the service port differs from that of R22.
• If a refrigeration gas leakage occurs during installation/servicing, be sure to ventilate fully.
If the refrigerant gas comes into contact with fire, a poisonous gas may occur.
• 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.
• 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.
• 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.
If the refrigerant gas leakage occurs and its concentration exceeds the marginal level, an oxygen starvation
accident may result.
• Be sure to carry out installation or removal according to the installation manual.
Improper installation may cause refrigeration trouble, water leakage, electric shock, fire, etc.
• Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a
qualified air conditioner technician or electrician.
Improper repair’s may result in water leakage, electric shock and fire, etc.

2-2. Refrigerant Piping Installation
2-2-1. 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.
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 discoloured portion (especially on the interior surface).
Otherwise, the expansion valve or capillary tube may become blocked with contaminants.
As an air conditioner using R410A incurs pressure higher than when using R22, it is necessary to choose adequate
materials.
Thicknesses of copper pipes used with R410A are as shown in Table 2-2-1. Never use copper pipes thinner than
0.8 mm even when it is available on the market.
Table 2-2-1 Thicknesses of annealed copper pipes
Joints
For copper pipes, flare joints or socket joints are used. Prior to use, be sure to remove all contaminants.
•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 2-2-3 to 2-2-6 below.
•Socket Joints
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 2-2-2.
Table 2-2-2 Minimum thicknesses of socket joints
2-2-2. 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 than lubricating oils used in the installed air-water heat pump 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.

Flare processing procedures and precautions
1) Cutting the Pipe
By means of a pipe cutter, slowly cut the pipe so that it is not deformed.
2) 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.
3) Insertion of Flare Nut
Table 2-2-3 Dimensions related to flare processing for R410A
Table 2-2-4 Dimensions related to flare processing for R22
Table 2-2-5 Flare and flare nut dimensions for R410A
4) Flare Processing
Make certain that a clamp bar and copper pipe have been
cleaned.
By means of the clamp bar, perform the flare processing
correctly.
Use either a flare tool for R410A or conventional flare tool.
Flare processing dimensions differ according to the type of flare
tool. When using a conventional flare tool, be sure to secure
“dimension A” by using a gauge for size adjustment.

Flare Connecting Procedures and Precautions
1) Make sure that the flare and union portions do not have any scar or dust, etc.
2) Correctly align the processed flare surface with the union axis.
3) 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 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 3-2-7 shows reference values.
NOTE
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.

2-3. Tools
2-3-1. Required Tools
The service port diameter of packed valve of the outdoor unit in the air-water heat pump 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.
• Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))
• Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)

2-4. Recharging Refrigerant
When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the
following steps.
CAUTION
• Never charge refrigerant exceeding the specified amount.
• If the specified amount of refrigerant cannot be charged, charge refrigerant in COOL mode.bit by bit
• 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.
Fig. 2-4-1 Configuration of refrigerant charging
Connect the charge hose to packed valve service
port at the outdoor unit’s gas side.
Recover the refrigerant, and check no refrigerant
remains in the equipment.
(For refrigerant charging, see the figure below.)
Connect the charge hose to the vacuum pump
adapter.
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.
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.
Keep the status as it is for 1 to 2 minutes, and ensure
that the compound gauge’s pointer does not return.
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.

NOTE
• 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.
Fig. 2-4-2
Cylinder with siphon

Cylinder without siphon
NOTE
R410A refrigerant is HFC mixed refrigerant.
Therefore, if it is charged with gas, the composition of
the charged refrigerant changes and the
characteristics of the equipment varies.

2-5. Brazing of Pipes
2-5-1. Materials for Brazing
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 expensive though it
excels in solder ability.
Phosphor bronze brazing filler
Phosphor bronze brazing filler is generally used to join
copper or copper alloy.
Low temperature 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.
REQUIREMENT
• 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.
• When performing brazing again at time of servicing,
use the same type of brazing filler.
2-5-2. Flux
Reason why flux is necessary
• By removing the oxide film and any foreign matter on
the metal surface, it assists the flow of brazing filler.
• 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.
Characteristics required for flux
• Activated temperature of flux coincides with the
brazing temperature.
• Due to a wide effective temperature range, flux is
hard to carbonize.
• 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 harmless to
the human body.
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.
Types of flux
•Non corrosive flux
Generally, it is a compound of borax and boric acid.
It is effective in case where the brazing temperature
is higher than 800°C.
•Activated flux
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.
Piping materials for brazing and used brazing
filler/flux
NOTE
• Do not enter flux into the refrigeration cycle.
• When chlorine contained in the flux remains within
the pipe, the lubricating oil deteriorates.
Therefore, use a flux which does not contain
chlorine.
• When adding water to the flux, use water which
does not contain chlorine (e.g. distilled water or ion-
exchange water).
• Remove the flux after brazing.
2-5-3. Brazing
As brazing work requires sophisticated techniques,
experiences based upon a theoretical knowledge, it
must be performed by a person qualified.
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.
CAUTION
Never use gas other than Nitrogen gas.

Copper - Copper Phosphor copper Do not use
Copper - Iron Silver Paste flux
Iron - Iron Silver Vapour flux

Brazing method to prevent oxidation
1) Attach a reducing valve and a flow-meter to the
Nitrogen gas cylinder.
2) Use a copper pipe to direct the piping material,
and attach a flow-meter to the cylinder.
3) 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.
4) When the Nitrogen gas is flowing, be sure to
keep the piping end open.
5) 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.
6) 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).
7) Remove the flux completely after brazing.

8OPERATION DESCRIPTION
8-1. Outline of Air
Conditioner Control
This air conditioner is a capacity-variable type air
conditioner, which uses DC motor for the indoor fan
motor and the outdoor fan motor. And the Variable
Cylinder Management Compressor (VCM Comp.)
which can change the motor speed in the range from
10 to 100 rps at 2 cylinder operation and the range from
10 to 50 rps at 1 cylinder operation is mounted. The DC
motor drive circuit is mounted to the indoor unit. The
compressor and the inverter to control fan motor are
mounted to the outdoor unit.
The entire air conditioner is mainly controlled by the
indoor unit controller.
The indoor unit controller drives the indoor fan motor
based upon command sent from the remote controller,
and transfers the operation command to the outdoor
unit controller.
The outdoor unit controller receives operation
command from the indoor unit side, and controls the
outdoor fan and the pulse motor valve. (P.M.V)
Besides, detecting revolution position of the
compressor motor, the outdoor unit controller controls
speed of the compressor motor by controlling output
voltage of the inverter and switching timing of the
supply power (current transfer timing) so that motors
drive according to the operation command.
And then, the outdoor unit controller transfers reversely
the operating status information of the outdoor unit to
control the indoor unit controller.
NOTE
As the compressor adopts four-pole brushless DC
motor, the frequency of the supply power from inverter
to compressor is two-times cycles of the actual number
of revolution.
8-1-1. Role of Indoor Unit
Controller
The indoor unit controller judges the operation
commands from the remote controller and assumes
the following functions.
• Judgment of suction air temperature of the indoor
heat exchanger by using the indoor temp. sensor.
(TA sensor)
• Judgment of the indoor heat exchanger temperature
by using heat exchanger sensor (TC sensor)
(Prevent-freezing control and super heat control,
etc.)
• Judgment of inlet indoor heat exchanger
temperature by using heat exchanger sensor (TCj
sensor)(Super heat control etc.)
• Judgment of suction air humidity of the indoor heat
exchanger by using humidity sensor. (Hu sensor)
• Louver motor control
• Indoor fan motor operation control
• LED (Light Emitting Diode) display control
• Transferring of operation command signal (Serial
signal) to the outdoor unit
• Reception of information of operation status (Serial
signal including outside temp. data) to the outdoor
unit and judgment/display of error
• Air purifier operation control
• Moving panel control
8-1-2. Role of outdoor unit
controller
Receiving the operation command signal (Serial
signal) from the indoor unit controller, the outdoor unit
performs its role.
• Detection of inverter input current and current
release operation
• Over-current detection and prevention operation to
IGBT module (Compressor stop function)
• Compressor and outdoor fan stop function when
serial signal is off (when the serial signal does not
reach the board assembly of outdoor control by
trouble of the signal system)
• Transferring of operation information (Serial signal)
from outdoor unit controller to indoor unit controller
• Detection of outdoor temperature and operation
revolution control
• Defrost control in heating operation (Temp.
measurement by outdoor heat exchanger and
control for 4-way valve and outdoor fan)
• Compressor operation control
• Operation control of outdoor
fan motor
• P.M.V. control
• 4-way valve control
Operations followed

8-1-3. Contents of Operation
Command Signal (Serial
Signal)
From indoor unit controller to outdoor unit
controller
The following three types of signals are sent from the
indoor unit controller.
• Operation mode set on the remote controller
• Compressor revolution command signal defined by
indoor temperature and set temperature (Correction
along with variation of room temperature and
correction of indoor heat exchanger temperature are
added.)
• Temperature of indoor heat exchanger
• For these signals ([Operation mode] and
[Compressor revolution] indoor heat exchanger
temperature), the outdoor unit controller monitors
the input current to the inverter, and performs the
followed operation within the range that current does
not exceed the allowable value.
From outdoor unit controller to indoor unit
controller
The following signals are sent from the outdoor unit
controller.
• The current operation mode
• The current compressor revolution
• Outdoor temperature
• Existence of protective circuit operation
For transferring of these signals, the indoor unit
controller monitors the contents of signals, and
judges existence of trouble occurrence.
Contents of judgment are described below.
• Whether distinction of the current operation status
meets to the operation command signal
• Whether protective circuit operates
When no signal is received from the outdoor unit
controller, it is assumed as a trouble.
8-2. Basic Operation
