WARNINGS ON REFRIGERANT LEAKAGE

Check of Concentration Limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.

The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power etc. Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (m³)

≤ Concentration limit (kg/m³)

The concentration limit of R410A which is used in multi air conditioners is 0.3kg/m³.

NOTE 1 :

If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

e.g., charged amount (10kg)

Room A Room B Room C Room D Room E Room F

For the amount of charge in this example:

The possible amount of leaked refrigerant gas in rooms A, B and C is 10kg. The possible amount of leaked refrigerant gas in rooms D, E and F is 15kg.

Outdoor unit

e.g., charged amount (15kg)

Indoor unit

Important

NOTE : 2

The standards for minimum room volume are as follows.

(1) No partition (shaded portion)

(2) When there is an effective opening with the

adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).

Refrigerant piping

Indoor unit

(3) If an indoor unit is installed in each partitioned

room and the refrigerant tubing is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

NOTE

A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner. Caused from its characteristics, a current limit works on the direct current motor . When replacing the highperformance filter or when opening the service board, be sure to stop the fan. If an above action is executed during the fan operation, the protective control w orks to stop the unit oper ation, and the check code “P12” may be issued. However it is not a trouble. When the desired operation has finished, be sure to reset the system to clear “P12” error code using the leak breaker of the indoor unit. Then push the operation stop button of the remote controller to return to the usual operation.

Refrigerant

Check the used refrigerant name and use tools and materials of the parts which match with it.

For the products which use R410A refrigerant, the refrigerant name is indicated at a position on the outdoor unit where is easy to see. To prevent miss-charging, the route of the service por t is changed from one of the former R22.

For an air conditioner which uses R410A, never use other refrigerant than R410A. For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.

If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating cycle and an injury due to breakage may be caused.

Do not charge refrigerant additionally.

If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over the specified standard amount is charged and an abnormal high pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage or injury. Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute vacuuming, and then newly recharge the specified amount of liquid refrigerant. In this time, never charge the refrigerant over the specified amount.

When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other than R410A into the specified refrigerant.

If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating cycle resulted in cause of injury due to breakage.

After installation work, check the refrigerant gas does not leak.

If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

Never recover the refrigerant into the outdoor unit.

When the equipment is moved or repaired, be sure to recover the refr igerant with recovering device. The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as breakage or injury is caused.

Assembly/Cabling

After repair work, surely assemble the disassembled parts, and connect and lead the removed cables as before. Perform the work so that the cabinet or panel does not catch the inner cables.

If incorrect assembly or incorrect cable connection was done, a disaster such as a leak or fire is caused at user’s side.

WARNING

Insulator check

Ventilation

Be attentive to

electric shock

Compulsion

After the work has finished, be sure to use an insulation tester set (500V mugger) to check the resistance is 2M metal section (Earth position).

If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.

When the refrigerant gas leaks during work, execute ventilation.

If the refrigerant gas touches to a fire, poisonous gas generates. A case of leakage of the refrigerant and the closed room full with gas is dangerous because a shortage of oxygen occurs. Be sure to execute ventilation.

When checking the circuit inevitably under condition of the power-ON, use rubber gloves and others not to touch to the charging section.

If touching to the charging section, an electric shock may be caused.

When the refrigerant gas leaks, find up the leaked position and repair it surely.

If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the service valve, otherwise the refrigerant gas may leak into the room. The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

When installing equipment which includes a large amount of charged refrigerant such as a multi air conditioner in a sub-room, it is necessar y that the density does not the limit even if the refrigerant leaks.

If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.

For the installation/moving/reinstallation work, follow to the Installation Manual.

If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or fire is caused.

After repair work has finished, check there is no trouble.

If check is not executed, a fire, electric shock or injury may be caused. For a check, turn off the power breaker.

After repair work (installation of front panel and cabinet) has finished, execute a test run to check there is no generation of smoke or abnormal sound.

If check is not executed, a fire or an electric shock is caused. Before test run, install the front panel and cabinet.

Check the following items after reinstallation.

1) The earth wire is correctly connected.

2) The power cord is not caught in the product.

3) There is no inclination or unsteadiness and the installation is stable. If check is not executed, a fire, an electric shock or an injury is caused.

• New Refrigerant (R410A)

This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer.

1. Safety Caution Concerned to New Refrigerant

The pressure of R410A is high 1.6 times of that of the former refrigerant (R22). Accompanied with change of refrigerant, the refrigerating oil has been also changed. Therefore, be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into the refrigerating cycle of the air conditioner with new refrigerant during installation work or service work. If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident. Use the tools and materials exclusive to R410A to purpose a safe work.

2. Cautions on Installation/Service

(1) Do not mix the other refrigerant or refrigerating oil.

For the tools exclusive to R410A, shapes of all the joints including the service port differ from those of the former refrigerant in order to prevent mixture of them.

(2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools which are

specified for R410A.

(3) In the installation time, use clean pipe materials and work with great attention so that water and others do

not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc. Use the clean pipes.

Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.) (4) For the earth protection, use a vacuum pump for air purge. (5) R410A refrigerant is azeotropic mixture type refrigerant. Therefore use liquid type to charge the refrigerant.

(If using gas for charging, composition of the refrigerant changes and then characteristics of the air condi-

tioner change.)

3. Pipe Materials

For the refrigerant pipes, copper pipe and joints are mainly used. It is necessary to select the most appropriate pipes to conform to the standard. Use clean material in which impurities adhere inside of pipe or joint to a minimum.

(1) Copper pipe

The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type. When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe without

seam” and one with bonded oil amount 40mg/10m or less. Also do not use crushed, deformed, discolored (especially inside) pipes. (Impurities cause clogging of expansion valves and capillary tubes.)

Use the flare nuts which are attached to the air conditioner unit.

(2) Joint

The flare joint and socket joint are used for joints of the copper pipe. The joints are rarely used for installa-

tion of the air conditioner. However clear impurities when using them.

Page 8

4. Tools

(1) Required T ools for R410A

Mixing of different types 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 conv entional refrigerant (R22))

2) Tools exclusiv e 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.

3-10. Re-Installation

DANGER

Ask the dealer or an installation professional to re-install the air conditioner to a new place or move it to another place and to observe the following items. If the air conditioner is inappropriately by installed by yourself, it may cause electric shock or fire.

Do not install the air conditioner in the following places

• Do not install the air conditioner in any place within 1 m from a TV, stereo, or radio set. If the unit is installed in such place, noise transmitted from the air conditioner affects the operation of these appliances .

• Do not install the air conditioner near a high frequency appliance (sewing machine or massager for business use, etc.), otherwise the air conditioner may malfunction.

• Do not install the air conditioner in a humid or oily place, or in a place where steam, soot, or corrosive gas is generated.

• Do not install the air conditioner in a salty place such as seaside area.

• Do not install the air conditioner in a place where a great deal of machine oil is used.

• Do not install the air conditioner in a place where it is usually exposed to strong wind such as in seaside area

or on the roof or upper floor of a building.

• Do not install the air conditioner in a place where sulfureous gas generated such as in a spa.

• Do not install the air conditioner in a vessel or mobile crane. Be careful with noise or vibrations

• Do not install the air conditioner in a place where noise by outdoor unit or hot air from its air outlet annoys

your neighbors.

• Install the air conditioner on a solid and stable foundation so that it prevents transmission of resonating, operation noise and vibration.

• If one indoor unit is operating, some sound may be audible from other indoor units that are not operating.

3-11. Troubles and Causes

CAUTION

If any of the following conditions occur, turn off the main power supply switch and immediately contact the dealer :

• The operation lamps flash at short intervals (5 Hz) even though you have tried turning off the power

supply and turning on again after 2 or 3 minutes.

• Switch operation does not work properly.

• The main power fuse often blows out, or the circuit breaker is often activ ated.

• A foreign matter or water fall inside the air conditioner.

• Any other unusual conditions are observed.

Page 41

3-12. Information

Confirmation before operation

• Turn on the power switch 12 hours before starting the operation.

• Make sure whether earth wire is connected.

• Make sure the air filter is connected to the indoor

unit.

Heating capacity

• A heat pump system which absorbs heat from outside of the room and then discharges heat into the room is adopted for heating. If the outside temperature falls, the heating capacity decreases .

• When the outside temperature is too low, it is recommended to use this air conditioner together with other heating equipment.

Defrost during heating operation

• In heating operation, if there is frost on the outdoor unit, the operation changes automatically to the defrost operation (Approx. 2 to 10 minutes) to increase the heating efficiency.

• During defrost operation, the fan of the indoor unit stops.

3-minutes protection

Protective device (High pressure switch)

This device stops automatically an operation when excessive force is applied on the air conditioner.

If the protective device works , the operation stops and the operation lamp flashes.

When the protective device works, the indication

and the check code are displayed on the

display section of the remote controller. In the following cases, the protective device may work.

In cooling operation

• The suction port or discharge port of the outdoor unit is closed.

• A strong wind continuously blows to the discharge port of the outdoor unit.

In heating operation

• Dust or waste adheres excessively to air filter of the indoor unit.

• The discharge port of the indoor unit is closed.

If the protective device works, turn off the main power switch, solve the cause, and then start the operation again.

• When restarting the operation just after the operation has been stopped or the main power switch has turned on, the outdoor unit does not work for approx. 3 minutes in order to protect the air conditioner.

Power failure

• If a power failure occurred during operation, all operations stop.

• When the power is returned after a power f ailure, the operation lamp notifies the power-ON by flashing operation lamp on the remote controller.

• When restarting the operation, push button again.

Fan rotation in stopped unit

• In heating operation even in the stopped indoor unit, the fan rotates once for several minutes per approx. an hour when the other indoor unit is operating to protect the air conditioner.

Cooling/Heating operation of Super Modular Multi system air conditioner

• Although each indoor unit can be individually controlled in the Super Modular Multi system air conditioner, the cooling oper ation and the heating operation cannot be simultaneously performed in the multiple indoor units which are connected to an outdoor unit.

• If the cooling operation and the heating operation are simultaneously performed, the indoor unit

which executes cooling operation stops, and on the operation section lights up. On the other hand, the indoor unit which executes heating operation continues running. In a case that the manager of the air conditioner has fixed the operation to cooling or heating, an operation other than that set up is unavailab le. If an operation other than that

set up is executed, on the operation section lights up and the operation stops.

Characteristics of heating operation

• The wind is not out just after starting an operation. The hot wind starts to blow 3 to 5 minutes after (Time differs according to indoor/outdoor temperature.) the indoor heat exchanger has warmed up.

• During operation, the outdoor unit may stop if the outside temperature rises.

Page 42

3-13. Adjustment of Air Direction

To increase the cooling/heating efficiency , be sure to make proper use of the discharge flap for cooling or heating operation.

As the characteristics of air, cool air collects at lower levels, and hot air collects at higher levels.

Set t h e flap so that air blows out horizontally.

If cooling operation is performed with the flap blowing air downwards, the air outlet or surface of the flap will be wet with dew, and dewdrop may fall down.

CAUTION

[4-way Air Discharge Cassette Type]

In cooling operation

• Use the discharge flap with horizontal set point.

• When the air conditioner stops, the flap (adjustment plate of up/down air direction) directs downward automatically.

• When the heating operation is in READY states, the flap (adjustment plate of up/down wind direction) directs upward. The swinging starts after HEAT READY status cleared, SWING is displayed on the remote controller even if the heating operation is in READY status.

How to set up the air direction

Push during operation.

The air direction changes for every push of the button.

In heating operation

• Use the discharge flap with downward set point.

In HEAT operation

Direct the flap (adjustment plate of up/down air direction) downward. If directing at upward, hot air may not come to the foot.

3-14. Air Conditioner Operations and Performance

3 minutes protection function

3-minutes protection function prevents the air conditioner from starting for initial 3 minutes after the main power switch/circuit breaker is turned on f or re-starting the air conditioner .

Power failure

P o wer failure during operation will stop the unit completely.

• To restart the operation, push the START/STOP button on the remote controller.

• Lightning or a wireless car telephone operating nearby may cause the unit to malfunction. Turn off the main

power switch or circuit breaker and then turn them on again. Push the START/STOP button on the remote controller to restart.

Heating characteristics Preheating operation

The air conditioner will not deliver warm air immediately after it is turned on. Warm air will start to flow out after approximately 5 minutes when the indoor heat exchanger warmed up.

Warm air control (In heating operation)

When the room temperature reaches the set temperature, the fan speed is automatically reduced to prevent to blow cold draft. At this time, the outdoor unit will stop.

Defrosting operation

If the outdoor unit is frosted during the heating operation, defrosting starts automatically (for approximately 2 to 10 minutes) to maintain the heating capacity.

• The fans in both indoor and outdoor units will stop during the defrosting operation.

• During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor unit.

Heating capacity

In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating is called heat pump system. When the outside temperature is too low, it is recommended to use another heating apparatus in combination with the air conditioner.

Attention to snowfall and freeze on the outdoor unit

• In snowy areas, the air inlet and air outlet of the outdoor unit are often covered with snow or frozen up. If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming.

• In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside for freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or poor warming.

Air conditioner operating conditions

For proper performance, operate the air conditioner under the following temperature conditions:

Cooling operation

Dry operation

Outdoor temperature : –5°C to 43°C Room temperature : 21°C to 32°C (Dry valve temp.), 15°C to 24°C (Wet valve temp.)

CAUTION

Outdoor temperature : 15°C to 43°C (Maximum suction air temp. 46°C) Room temperature : 17°C to 32°C

Room relative humidity – less than 80 %. If the air conditioner operates in excess of this figure, the surface of the air conditioner may cause dewing.

Heating operation

If air conditioner is used outside of the above conditions, safety protection may work.

Outdoor temperature : –15°C to 15°C (Wet valve temp.) Room temperature : 15°C to 28°C (Dry valve temp.)

Capacity control

4 Oil level detection

control

1) According to the capacity demand command from the indoor controller, the inverter frequency control of the header and follower units is determined. The header unit sets the start order of the follower unit connected to the system and then starts the operation.

2) Two compressors in the outdoor unit rotate every stop of compressor and exchanges the start order when the compressor will be ON in the next time.

3) When two or more follower units are connected, if the system thermostat is OFF, the rotation is judged every compressor-OFF of the follower unit and the start priority order of the follower units in the next start time is exchanged.

1) Based upon the detected temperature of TK1 to TK4 sensors, whether the right amount of oil is included in the compressor case or not is judged. The header unit and follower unit perform this control individually.

2) From relation between the detected temperature of the operating compressor TK1 or TK2 and detected temperature of TK3, TK4, whether oil level in the compressor case is right or not is judged. If it is insufficient, the control shifts to the oil equation control.

3) This control is usually performed during operation of the compressor.

• Min. frequency: 26Hz

• The detection is per-

formed in both cases of operation of a compressor and operation of two compressors.

Oil equation control

6 Refrigerant/Oil

recovery control

This control is provided to prevent the oil short in the compressor of each outdoor unit. This control is basically performed by ON/OFF operation of the solenoid valves SV3A, SV3B, SV3C, SV3D. (For the schematic diagram of oil equation control.)

(1) Normal oil equalizing operation

This control is used when the oil level down has been detected for a long time.

(2) Oil equation control

This control supplies oil accumulated in the oil cylinder of each outdoor unit to the outdoor unit in which oil level moved down. This control is performed during compressor-ON of the header unit when oil level judgment result of the header unit shows “Short” or the oil equation demand is issued from the system of even a header unit. In a case of system with a header unit (No follower unit is connected.), this control is not executed.

(3) Oil-short protective control

If an oil equation control is executed, the protection stops when the status of oil short continues for 30 minutes, and it restarts after 2 minutes and 30 seconds after. After then, if the protection stop is repeated 3 times, an error is determined. (Restart is not performed.) The error code is “H07”.

(1) In cooling operation, this control is executed to regularly

recover the refrigerating oil stagnated in gas inter-unit pipe or indoor unit to the outdoor unit when the compressor driving command is weak, and to prevent refrigerant accumulation in the outdoor heat exchanger while low ambient cooling operation is performed. This control is managed by the header outdoor unit.

1) Control conditions

• Cooling oil recovery control is executed every 2 hours approximately.

2) Contents of control

• Recovery time continues for approx. 2 or 3 minutes though it differs according to the system capacity.

(2) Refrigerant recovery control in heating room

During heating operation, this is executed to recover liquid refrigerant stagnated in the stopped indoor unit. It is also used to recover oil in the outdoor heat exchanger in heating overload operation except with defrost condition. This control is managed by the header outdoor unit.

1) Heating refrigerant recovery control is executed every an hour approximately.

2) Recovery time continues for approx. 2 to 10 minutes though it differs according to the load condition.

7 Defrost control

(Reverse defrost method)

(1) Defrost start condition

In heating operation, the operating time is integrated when the detected TE sensor temp was lower than -2°C, and when 25 minutes have passed in the initial time after the compressor started and 55 minutes in the second time and after.

(2) Contents of control

• If the outdoor units are combined, the defrost operation

forcedly continues for 2 minutes if the defrost operation has been once started.

(3) Stop conditions of defrost operation

• If the outdoor units are combined, the fan drive and compres-

sor inverter frequency may be controlled by Pd pressure during defrost operation.

• Dur ing defrosting operation, all the solenoid valves of 4-way are OFF and all compressors are driven.

(1) SV2 gas balance control

This control is executed to balance the gas when opening SV2 while the compressor is off, in order to decrease the activation load in the next compressor-ON time. This control is individually executed by the header outdoor unit and each follower outdoor unit.

(2) SV2 high pressure release control

This control is to control pressure rising in low-frequency operation of the inverter.

(3) SV2 low pressure release control

This control is to prevent quick pressure dropping in transient operation. This control is individually executed by the header outdoor unit.

This control is executed as necessary except during stop time and thermostat-OFF time.

(4) SV41, 42 low pressure release control

This control is to prevent low pressure dropping and is individually executed by the header unit and each follower unit.

This control is executed during defrost operation, heating start pattern control operation, and cooling operation.

(5) SV5 high pressure release control

This control is to prevent high pressure rising and is executed for the header unit only.

This control is to forcedly stop the compressor in each outdoor unit according to Pd pressure. It is individually executed by the header unit and each follower unit.

(1) Contents of control

• The compressor stops when Pd pressure is over 3.5MPa.

10 Case heater

control

11 IPDU control IPDU controls the inverter compressor by command frequency,

The case heater output includes compressor case heater and accumulator case heater. This control is to prevent accumulation of refrigerant in the compressor case by turning of the power of heater while the compressor stops, and it is executed in all the outdoor units.

If electricity is not turned on for a specified time before the test run after installation, a trouble of the compressor may be caused. When the power has been interrupted for a long time and the operation starts from the status as it was, it is desirable to turn on the power before start of operation as per the test run time.

This control is used often together with the compressor winding heating control. In this case, the power sound may be heard but it is not a trouble.

(1) Contents of control

• Turns on during compressor-OFF

• Turns off when the detected TO sensor temp is 28°C or higher, and turns on when it is 25°C or lower

• The operation continues for 10 minutes after compressor-

OFF changed to compressor-ON.

The main controls of IPDU control P.C. board are described below.

(1) Current release control

The output frequency is controlled by AC input current value which is detected by inputting current sensor (CT) on the control P.C. board to prevent the inverter input current from rising higher than the specified value.

1) This control protects IGBT overheat preventive protection by the thermistor (TH temp) on the compressor driving module in IPDU.

∗ For TH temperature, the higher one of IPDU1 temperature and

IPDU2 temperature is applied.

(3) Over-current protective control

1) The compressor stops when IPDU control P.C. board detects over-current.

(4) Compressor case thermo control

1) When the compressor case thermostat works, the compressor stops.

2) When the compressor stops, 1 is counted to the error count, and the compressor reactivates after 2 minutes and 30 seconds. After reactivated, the error count is cleared if the operation continues for 10 minutes or more.

3) The error is determined with error count 4. The error “H04” is displayed in compressor 1 and “H14” in compressor 2, respectively.

(1) High pressure SW control

• The high-pressure SW is usually closed and connected to IPDU.

1) The compressor driver stops when high pressure SW at inverter compressor operates.

2) When the compressor driver stops, 1 is counted to the error count, and the compressor driver reactivates after 2 minutes 30 seconds. After reactivated, the error count is cleared if the operation continues for 10 minutes or more.

3) The error is determined with error count 4. The error “P04” is displayed.

• TH sensor is provided to IPDU1 and 2 each.

• The case thermostat is usually closed and connected to the interface P.C. board.

1. Cooling operation in low ambient temperature

1) When low pressure is lowered, the freeze pre vention control by the indoor unit TC sensor may decrease the frequency.

2) When low pressure is lowered, the cooling capacity control may decrease the frequency.

3) When discharge temp. sensor value lowers below 60°C, the frequency may be increased over the receive command from the indoor unit.

2. PMV (Pulse Motor Valve) for outdoor unit

1) When the power is turned on, a tap sound to initialize PMV is heard. If this sound is not heard, PMV operation error is considered. However, this sound may not be heard at a place where outside sound takes precidence.

2) Do not remove the driving part (Head part) of PMV during operation. It may cause error in opening.

3) When transporting (replacing) the set, never keep the driving part removed. The valve is closed, and the valve is damaged by sealed liquid compression.

4) When removing the driving part and attaching it again, push in it securely until a “click” sound can be heard. Then, turn off the power once, and turn on the power again.

8-3. Check at Main Power-ON

After turning on the main power of the indoor units and outdoor unit in the refrigerant line to be ex ecuted with a test operation, check the following items in each outdoor and indoor unit.

(After turning on the main power, be sure to check in order of indoor unit <Check on outdoor unit>

1. Check that all the rotary switches, SW01, SW02, and SW03 on the interface P.C. board of the header unit are set up to “1”.

2. If other error code is displayed on 7-segment [B], remove the cause of troub le referring to “9. T roubleshooting”.

3. Check that [L08] is displayed on 7-segment display [B] on the interf ace P.C. board of the header unit. (L08: Indoor address unset up)

(If the address setup operation has already finished in service time, etc, the above check code is not displayed, and only [U1] is displayed on 7-segment display [A].)

If a frame is not displayed as shown in the above right figure, the power of the remote controller is not normally turned on. Therefore check the following items.

• Check power supply of indoor unit.

• Check cabling between indoor unit and remote controller.

• Check whether there is cutoff of cable around the indoor control P.C. board or not, and check connection

failure of connectors.

• Check failure of transformer for the indoor microcomputer.

• Check indoor control P.C. board failure.

8-4. Address Setup

After power-ON, set up the indoor address from the interface P.C. board of the header unit.

(The address setup operation cannot be performed by power-ON only.)

8-4-1. Cautions

1. It requires approx. 5 minutes usually for 1 line to automatically set up address. Howe ver in some cases, it may require maximum 10 minutes.

2. It is unnecessary to operate the air conditioner for address setup.

3. Manual address setup is also available besides automatic setup. Automatic address: Setup from SW15 on the interface P.C. board of the header unit Manual address: Setup from the wired remote controller.

Turn on power of indoor unit in refrigerant line to which address is set up. Turn on power of all the outdoor units in refrigerant line to which address is set up. Check that [L08] is displayed on 7-segment display [B] on the interface P.C. board of the header

unit in the system to which address is set up. Confirm the corresponding items in “8-4-3 Address setup procedure”, and then set up address

according to the operation procedure. (Be sure that the setup operation may differ in group control or central control.) Note) Address cannot be set up if switches are not operated.

• After address setup, [U1] is displayed in 7-segment display section.

• For follower outdoor units, [U2] to [U4] are displayed in 7-segment display [A].

• If an error code is displayed in 7-segment display [B], remove the cause of trouble referring to

“9. Troubleshooting”.

Using 7-segment display function, check the system infor mation of the scheduled system. (This check is executed on the interface P.C. board of the header unit.)

8-4-3. Address Setup Procedure

In this air conditioner, it is required to set up address to the indoor unit before starting operation. Set up the address according to the following setup procedure.

CAUTIONS

1. Set up address after wiring work.

2. Be sure to turn on the power in order of indoor unit → outdoor unit. If turning on the power in the reverse order, a check code [E19] (Error of No. of header units) is output. When a check code is output, turn on the power again.

3. It requires maximum 10 minutes (Usually, approx. 5 minutes) to set up automatically an address to 1 line .

4. To set up an address automatically, the setup at outdoor side is necessary. (Address setup cannot be performed by power-ON only.)

5. To set up an address, it is unnecessary to operate the air conditioner.

6. Manual address setup is also available besides automatic setup. Automatic address : Setup from SW15 on the interface P.C. board of the header unit Manual address : Setup from the weird remote controller ∗ It is temporarily necessary to set the indoor unit and wired to 1 : 1.

(In group operation and in time without remote controller)

Automatic Address Setup

Without central control : To the address setup procedure 1 With central control : To the address setup procedure 2

(However, go to the procedure 1 when the central control is performed in a single refrigerant line.)
