Note 1 : The cooling capacities and electrical characteristics are measured under the conditions speciied by JIS B 8616 based

on the reference piping. The reference piping consists of 3 m of main piping and 2 m of branch piping connected with 0 meter height.

Note 2 : The sound level is measured in an anechoic chamber in accordance with JIS B8616. Normally, the values measured in

the actual operating environment become larger than the indicated values due to the effects of external sound.

Note : Rated conditions Cooling : Indoor air temperature 27°C DB/19°C WB, Outdoor air temperature 35°C DB

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 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.

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 materials 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, pressure in the refrigeration cycle becomes abnormally 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 conditioner 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 discolored 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 contaminants.

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.

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.

– 31 –

Page 32

c) Insertion of Flare Nut d) 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.

Table 7-2-3 Dimensions related to flare processing for R410A

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.

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.

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.

Connect the charge hose to packed valve service port at the outdoor unit’s gas side.

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 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.

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.



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.

(For refrigerant charging, see the figure below.)

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 composition of the charged refrigerant changes and the characteristics of the equipment varies.

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 expensive 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.

Fig. 7-4-2

7-5-2. Flux

(1) Reason why flux is necessary

Electronic

balance

Siphon

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.

• 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 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.

(3) Types of flux

• Noncorrosive 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.

(4) Piping materials for brazing and used braz-

ing filler/flux

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.

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.

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 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

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 frequency control up to a unit of 0.6Hz to stabilize 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.

1) Cooling fan control The 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).

At 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.

When the discharge temperature sensor is

abnormal or the sensor comes off the holder, the fan does not rotate with high speed, but a protective device works.

When 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.

This control function lowers fan tap according to

TE sensor value when outdoor temperature is high.

When a status TE > 20°C is detected continuously for 5 minutes, the operation may stop. This 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.

If 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.

This control function does not work for 30 minutes after activation, 1 minute after defrosting, and during defrost operation.

2. Outdoor fan control (Object: SM560)

The outdoor fan is controlled by TO sensor and the revolutions frequency of the compressor (rps). The outdoor fan is controlled by every 1 tap of DC fan control (8 taps). According to each operation mode, the fan is operated by selecting an outdoor fan operation tap in the following table based upon the conditions of TO sensor and the compressor operation (rps).

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

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.

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

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

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 ‘P04’ is 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.

6. 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.

If 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

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.

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

value.

The value to be corrected is based upon the following control diagram and correction value table.

8. 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.

11. REPLACEMENT OF SERVICE INDOOR P.C. BOARD

[Requirement when replacing the service indoor P.C. board assembly]

In the non-volatile memory (Hereinafter said EEPROM, IC10) installed on the indoor P.C. board before replacement, the type and capacity code exclusive to the corresponding model have been stored at shipment from the factory and the important setup data such as system/indoor/group address set in (AUTO/MANUAL) mode or setting of high ceiling selection have been stored at installation time. Replace the service indoor P.C. board assembly according to the following procedure.

After replacement, check the indoor unit address and also the cycle by a test run.

CASE 1

Before replacement, power of the indoor unit can be turned on and the setup data can be readout from the wired remote controller.

Read EEPROM data *1 (ref. P89)

Replace service P.C. board & power ON *2 (ref. P89)

Write the read data to EEPROM *3 (ref. P90)

Power reset (All indoor units in the group when group operation)

CASE 2

Before replacement the setup data can not be readout from the wired remote controller.

Replace service P.C. board & power ON *2 (ref. P89)

Write the data such as high ceiling setup to EEPROM (According to the customers’ information) *3

Power reset (All indoor units in the group when group operation)

SET DATA

R.C. No.

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.

Push

In the group control, the unit No and then all the indoor units in the group control are selected. In this time, fans of all the selected indoor units are turned on. (Fig. 1)

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

and OFF of 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.
