7. REFRIGERANT 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 refrigerat-

ing 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.

7-1. 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 materi-

als exclusive for R410A, it is necessary to carry out

installation/servicing safely while taking the following

precautions into consideration.

(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.

(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.

(3) 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.

(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.

(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.

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.

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.

Improper repair’s may result in water leakage,

electric shock and fire, etc.

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) 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.

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 7-2-1. Never use copper

pipes thinner than 0.8 mm even when it is

available on the market.

(2) Joints

For copper pipes, flare joints or socket joints are

used. Prior to use, be sure to remove all con-

taminants.

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.

b) 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 7-2-2.

Table 7-2-2 Minimum thicknesses of socket joints

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.

(1) Flare Processing Procedures and Precautions

a) Cutting the Pipe

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.

(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.

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 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.

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.

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.

Tools exclusive for R410A (The following tools for R410A are required.)

Tools whose specifications are changed for R410A and their interchangeability

(Note 1) When flaring is carried out for R410A using the conventional flare tools, adjustment of projection

margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary.

(Note 2) Charging cylinder for R410A is being currently developed.

General tools (Conventional tools can be used.)

In addition to the above exclusive tools, the following equipments which serve also for R22 are necessary

as the general tools.

(1) Vacuum pump

Use vacuum pump by

attaching vacuum pump adapter.

(2) Torque wrench

(3) Pipe cutter

(4) Reamer

Connect the charge hose of 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.

7-4. Recharging of Refrigerant

When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the

following steps.

Never charge refrigerant exceeding the specified amount.

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.

Fig. 7-4-2

7-5. Brazing of Pipes

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.

(2) Phosphor bronze brazing filler

Phosphor bronze brazing filler is generally used

to join copper or copper alloy.

(3) 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.

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.

7-5-2. Flux

(1) 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.

(2) 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 harm-

less 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.

(3) Types of flux

•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.

•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.

(4) Piping materials for brazing and used braz-

ing filler/flux

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.

7-5-3. 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.

Never use gas other than Nitrogen gas.

(1) Brazing method to prevent oxidation

Attach a reducing valve and a flow-meter to

the Nitrogen gas cylinder.

Use a copper pipe to direct the piping mate-

rial, and attach a flow-meter to the cylinder.

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.

When the Nitrogen gas is flowing, be sure to

keep the piping end open.

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.

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.

9-2-2. Outline of Main Controls

1. Pulse Modulating Valve (PMV) control

1) For PMV, SM560 is controlled with 45 to 500 pulses and SM800 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 in both cooling and heating opera-

tions.

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

1) This function controls the operation frequency,

that is, lowers the operation frequency when

the discharge temperature has not lower or

the discharge temperature has rapidly risen

during PMV control. It subdivides the fre-

quency control up to a unit of 0.6Hz to stabi-

lize the cycle.

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 operation for 10 minutes.

If the abnormal stop zone has been detected

by 4 times without clearing of counter, an

error ‘P03’ is displayed.

* The cause is considered as excessively little

amount of refrigerant, defective PMV, or

clogging of cycle.

3. Current release control

The output frequency and the output voltage are

controlled by AC current value detected by T02

on the outdoor P.C. board so that input current of

the inverter does not exceed the specified value.

status does not output an error code and is

assumed as usual status of thermo-OFF. The fan

restarts after approx. 2 minutes 30 seconds and

this intermittent operation is not a trouble.

SIf the status in item R is frequently found, it is

considered that the filter of suction part of the

indoor unit is dirty. Clean the filter and restart the

operation.

TThis control function does not work for 30 min-

utes after activation, 1 minute after defrosting,

and during defrost operation.

Control for fan tap by outdoor temperature in normal operation

1) Cooling fan control

QThe outdoor fan is controlled by TE sensor.

(Cooling: Temperature conditions after medium

term)

The cooling fan is controlled by every 1 tap of DC

fan control (14 taps).

RAt the activation time, although the maximum fan

tap in the following table are fixed for 60 seconds,

after then the fan may not rotate with high speed

for several minutes because the fan is controlled

by TE sensor value. It is not an abnormal status.

SWhen the discharge temperature sensor is

abnormal or the sensor comes off the holder, the

fan does not rotate with high speed, but a protec-

tive device works.

TWhen the outdoor fan does not rotate with high

speed, judge a fan error by comparing the control

data in the following table with TO and TE values.

3. 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.

4. Short intermittent operation preventive control

QThe 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.)

RIf the equipment is stopped from the remote controller, the operation does not continue.

5. High-voltage suppression TE control (Only for SM800)

QThis control suppresses that voltage becomes abnormally higher during cooling operation.

RStop the compressor under condition of TE ≥ 67°C, and count 1 on the error count.

SAfter 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.

TWhen TE ≥ 67°C is detected again within 10 minutes, 1 is added to the error count and restart is

repeated.

UIf the error counts 10 are recognized, it is determined as an error and restart is not performed. Error

code ‘P04’ is displayed.

VAfter restarting the compressor, continue controlling by using 70% to 90% of the control value of the

current release control for minimum 30 minutes.

6. Over-current preventive control

QThis control function stops the compressor when over-current preventive circuit has detected an

abnormal current.

RThe compressor restarts with error count 1 after 2 minutes 30 seconds.

SIf the error counts 4 are recognized, it is determined as an error and restart is not performed. Error

code ‘H01’, ‘H02’ or ‘P26’ is displayed.

7. Current release value shift control

1) Object: SM800

Q 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.

R This control function corrects the current release control value ( 1) in item 3 of 9-2-2 by TO sensor

value.

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.

2. How to set by the switch on the network adapter P.C. board

When the remote controller cannot be found or when you don’t want to change setting of the network address

No. from the remote controller, use the setup switch SW01 on the network adapter P.C. board (Network address

No. setup switch) to set the address No.

(1) Turn off the power.

(2) Turn  of the address No. setup switch SW01 to ON

side. Accordingly the address No. set on the remote

controller is invalidated. (See Fig. 2.)

(3) Set the network address No. with combination of ON

and OFF of  to  of the address No. setup switch

SW01. The relation between combination of ON/OFF

and address No. is described in Table 2. The right

figure (Fig. 3) shows an example of case that the

address No. is set to 16.

When the network address No. has been changed,

be sure to turn of power of the central control remote

controller again or to reset the remote controller using

the reset hole on the operation panel of the central

control remote controller.

12-4. Display and Operation of Main Remote Controller and Central Control Remote

Controller

1. Turn on all the power supplies of the air conditioner, and then turn on power of the central control remote

controller (Line 16 RBC-SXC1P, Line 64 TCB-SC641). If both power supplies are simultaneously turned on or

if they are turned on reversely, the check code [97] may be temporarily displayed on the central remote

controller. When settings of connecting cables and central control address are correct, the connected air

conditioner is displayed on the central control remote controller.

2. As shown in the following table, there is difference of LCD between main remote controller (RBC-AMT21)

and the central control remote controller and also there are restriction and others of operation.

3. When using the remote controller together with the former one (RBC-AM1, AT1), the display on the main

remote controller differs if [Last-push priority/Center/Operation Prohibited] is selected from the central control

remote controller.

Cautions

Display of air speed selection differs.

In duct type

Air speed becomes [H] and [FIX].

When handling main remote controller, [AUTO] is

not displayed. If [AUTO] is selected at center side,

[AUTO] is displayed on the main remote controller.

In this time, the air speed becomes [HH].

On the central remote controller, only [AUTO] is

displayed. The display on the main remote

controller changes to [AUTO] by changing the

setup temperature/louver, and the air speed is

automatically selected.

On the central remote controller, only [LOUVER] is

displayed. It is displayed while flap is swinging,

and the setup operation of [LOUVER] becomes

selection of swing ON/OFF.

To set up the air direction, use the main remote

controller.

In a model type without air direction adjustment

The function of long-pushing operation for the

check button differs. If the check reset operation

on the central remote controller is performed

during operation of air conditioner, the operation

stops once, and then the operation restarts. (Error

of air conditioner is cleared.)

Display of check code differs.
