3-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to termnal, all supply ciucuits must disconnected.

3-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

Use new refrigerant pipes.

In case of using the existing pipes for R22, be careful with the followings.

· Be sure to clean the pipes and make sure that the insides of the pipes are clean.

· Change flare nut to the one provided with this product. Use a newly flared pipe.

· Avoid using thin pipes.

Make sure that the inside and outside of refrigerant piping is clean and it has no contamination such as sulfur hazardous for use, oxides, dirt, shaving particles, etc. In addition, use pipes with specified thickness.

Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.

Store the piping to be used indoors during installation and both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.)

If dirt, dust or moisture enter into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Do not use refrigerant other than R410A.

If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.

Use a vacuum pump with a reverse flow check valve.

Vacuum pump oil may flow back into refrigerant cycle and that can cause deterioration of refrigerant oil etc.

Use the following tools specifically designed for use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Tools for R410A Gauge manifold Charge hose

Gas leak detector

Torque wrench

Flare tool Size adjustment gauge Vacuum pump adaptor

Electronic refrigerant charging scale

Handle tools with care.

If dirt, dust or moisture enter into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigerant oil applied to flares and flange connections.

If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.

Ventilate the room if refrigerant leaks during

Charge refrigerant from liquid phase of gas cylinder.

If the refrigerant is charged from gas phase, composition change may occur in refrigerant and the efficiency will be lowered.

operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

[1] Cautions for service

(1) Perform service after collecting the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

· Check that cylinder for R410A on the market is syphon type.

· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

Cautions for refrigerant piping work

New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working pressure of R410A is 1.6 time higher than that of R22, their sizes of flared sections and flare nuts are different.

1Thickness of pipes Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness shown below. (Never use pipes of 0.7mm or below.)

2Dimensions of flare cutting and flare nut The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that, R410A is a refrigerant, which has higher risk of leakage because of its working pressure higher than that of other refriger ants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A have been speci fied separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also have partly been changed to increase intensity as shown below. Set copper pipe correctly referring to copper pipe flaring dimensions for R410A below. For 1/2” and 5/8”, the dimension B changes. Use torque wrench corresponding to each dimension.

9-4. M-NET WIRING METHOD

(Points to note) (1) Outside the unit, transmission wires should stay away from electric wires in order to prevent electromagnetic noise from

making an influence on the signal communication. Place them at intervals of more than 5cm. Do not put them in the same

conduit tube. (2) Terminal block (TB7) for transmission wires should never be connected to 220~240V power supply. If it is connected, electronic parts on M-NET P.C. board may be burn out. (3) Use 2-core x 1.25mm

received normally if different types of transmission wires are put together in the same multi-conductor cable. Never do this

because this may cause a malfunction.

It would be ok if M-NET wire (non-polar, 2-cores) is arranged in addition to the wiring for A-control.

(4) Earth only one of any appliances through M-NET transmission wire (shield wire). Communication error may occur due to

the influence of electromagnetic noise. “Ed” error will appear on the LED display of outdoor unit. “0403” error will appear on the central-control remote controller.

If there are more than two earthing spots on the shield wire, noise may enter into the shield wire because the earth wire

and shield wire form one circuit and the electric potential difference occurs due to the impedance difference among earth-

ing spots. In case of single spot earthing, noise does not enter into the shield wire because the earth wire and shield wire

do not form one circuit.

To avoid communication errors caused by noise, make sure to observe the single spot earthing method described in the

installation manual.

M-NET wiring

(1) Use 2-core × 1.25mm² shield wire for electric wires. (Excluding the case connecting to system controller.)

(A, B, S) on M-NET terminal block should be individually wired to the other outdoor unit’s terminal, i.e. A to A, B to B and S to S.In this case, choose one of those outdoor units and drive a screw to fix an ground wire on the plate as shown on the right figure.

9-4-1. M-NET address setting

In A-control models, M-NET address and refrigerant address should be set only for the outdoor unit. Similar to CITY MULTI system, there is no need to set the address of outdoor unit and remote controller. To construct a central control system, the setting of M-NET address should be conducted only upon the outdoor unit. The setting range should be 1 to 50 (the same as that of the indoor unit in CITY MULTI system), and the address number should be consecutively set in a same group.

Address number can be set by using rotary switches (SW11 for ones digit and SW12 for tens digit), which is located on the M-NET board of outdoor unit. (Initial setting: all addresses are set to “0”.)

9-4-2. Refrigerant address setting

In case of multiple grouping system (multiple refrigerant circuits in one group), indoor units should be connected by remote controller wiring (TB5) and the refrigerant address needs to be set. Leave the refrigerant addresses to “00” if the group setting is not conducted. Set the refrigerant address by using DIP SW1-3 to -6 on the outdoor controller board.

11-2. CHECK POINT UNDER TEST RUN

(1) Before test run

• After installation of indoor and outdoor units, piping work and electric wiring work, re-check that there is no refrigerant leak-

age, loosened connections and incorrect polarity.

• Measure impedance between the ground and the power supply terminal block (L, N) on the outdoor unit by 500V Megger

and check that it is 1.0M" or over.

wDo not use 500V Megger to indoor/outdoor connecting wire terminal block (S1, S2, S3) and remote controller terminal block (1, 2). This may cause malfunction.

• Make sure that test run switch (SW4) is set to OFF before turning on power supply.

• Turn on power supply 12 hours before test run in order to protect compressor.

• For specific models which requires higher ceiling settings or auto-recovery feature from power failure, make proper changes

of settings referring to the description of “12. FUNCTION SETTING”.

Check for correct motion of auto-vanes.

The outdoor unit features automatic capacity control to provide optimum fan speeds. Therefore, the fan keeps running at a low speed to meet the current outside air condition unless it exceeds its available maximum power. Then, in actuality, the fan may stop or run in the reverse direction depending on the outside air, but this does not mean malfunction.

Check if cool air blows and water is drained.

• In case of test run, the OFF timer will be activated, and the test run will automatically stop after two hours.

• The room temperature display section shows the pipe temperature of indoor units during the test run.

• Check that all the indoor units are running properly in case of simultaneous twin and triple operation. Malfunctions may not be displayed regardless of incorrect wiring. w1 After turning on the power supply, the system will go into startup mode, “PLEASE WAIT” will blink on the display section of the room temperature, and lamp(green) of the remote controller will flash.

remote controller indicate the controller that detected abnormality.

(Note) “Indoor unit” in the text indicates M-NET P.C. board in outdoor unit.

Case Judgment and action

1 There are two or more same

address of controller of outdoor unit, indoor unit, FRESH MASTER, or LOSSNAY.

2 Noise has entered into trans-

mission signal and signal was transformed.

1 Error is detected if waveform is

transformed when wiring works of transmission wire of outdoor unit, indoor unit, FRESH MASTER or LOSSNAY are done, or polarity is changed with the power on and transmission data collide each other.

2

Defective transmitting receiving circuit of transmission processor

3 Transmission data is changed

by the noise on transmission.

1 Transmission processor could

not transmit because short cycle voltage of noise and the like have entered into transmission wire continuously.

2 Transmission quantity has

increased and transmission is not possible because there was wiring mistake of terminal block for transmission wire (TB3) and terminal block for central control (TB7) in outdoor unit.

3 Transmission are mixed with

others and occupation rate

on transmission wire rose

because of defective repeater (a function to connector or

disconnect transmission of

control and central control

system) of outdoor unit, then

abnormality is detected.

1 Data of transmission proces-

sor or unit processor is not transmitted normally because of accidental trouble such as noise or thunder surge.

2 Address forwarding from unit

processor is not transmitted normally because of defective transmission processor hardware.

Search the unit with same address as abnormality occurred. If the same address is found, shut of the power supply of outdoor unit and indoor unit and FRESH MASTER or LOSSNAY at the same time for 2 minutes or more after the address is corrected, and turn the power on again. Check transmission waveform or noise on transmission wire. 1 If the works of transmission wire is done

with the power on, shut off the power supply of outdoor unit and indoor unit and FRESH MASTER or LOSSNAY at the same time for 2 minutes or more, and turn the power on again.

2 Check transmission waveform or noise on

transmission wire.

1 Check if transmission wire of indoor unit,

FRESH MASTER, LOSSNAY, or remote

controller is not connected to terminal block

for central control (TB7) of outdoor unit.

2 Check if transmission wire of indoor unit,

FRESH MASTER or LOSSNAY is not

connected to terminal block for transmission

wire of outdoor unit.

3 Check if terminal block for transmission wire

(TB3) and terminal block for central control (TB7) is not connected.

4 Check transmission waveform or noise on

transmission wire.

Turn off the power supply of outdoor unit and indoor unit and FRESH MASTER or LOSSNAY at the same time for 2 minutes or more, and put the power on again. System returns normally if abnormality was accidental malfunction. If the same abnormality generates again, abnormality-generated controller may be defective.

[for wired remote controller]

Check the following table to see whether there is a simple solution to your problem.

The room neither gets cool nor

Problem

warm very much.

The unit does not blow air out right away in the heating mode. The unit stops operating before arriving at the set temperature in the heating mode.

The airflow direction suddenly changes.

Air direction does not move (change). (Up/down vane, left/right louver)

When changing the airflow direction, the vanes make at least a complete rotation before stopping in place.

There is a “swishing” noise that occurs from the unit when water flows.

Unit occasionally makes a gurgling sound.

Unit occasionally thuds.

Outdoor unit occasionally rattles.

Clean the filter. (Dust and debris that are collected in the filter will decrease air-flow.) Check the temperature setting and adjust it if necessary. Increase the space surrounding the outdoor unit. Is the air intake or air outlet blocked? Is a window or door open? The unit is preparing to deliver warm air. Frost forms when the outdoor temperature is low and humidity is high. Wait for about 10 minutes for the frost to melt. After 1 hour of cooling-mode operation with the airflow in a downward direction, the unit will automatically change to the “Horizontal air-flow” mode. This is to prevent any moisture that may have collected from dripping. When the unit is in the heating or defrosting mode, it will automatically change to the “Horizontal airflow mode”. The vanes will go through a test run before they situate into the specified angle.

1) Check whether the vane has been set to a fixed position (check whether the vane motor connector has been removed).

2) Check whether the unit has a function for switching the air direction. If the unit does not have this function, "FUNCTION DOESN'T EXIST" appears when you press the remote control's UP/DOWN VANE or LOUVER button.

The vanes will go through a test run before they situate into the specified angle.

This sound is made when refrigerant inside of the unit is flowing or refilling.

Not an error. This sound is caused by the flow of the refrigerant in the air conditioner being switched.

Not an error. This sound is emitted when the air conditioner (outdoor unit) starts operating.

Not an error. This sound is caused by the blower air volume control that the outdoor unit performs to maintain the optimum operation status.

Solution Problem Solution

A ticking noise is heard from inside of the unit.

An odour is detected in the room.

A white mist is expelled from the indoor unit.

Water or moisture is expelled from the outdoor unit.

The indicators of the remote controller do not light up when operated. CENTRALLY CONTROLLED indicator is displayed in the remote controller.

The start and stop functions are not available just after restarting the unit.

Fan speed does not match set fan speed during DRY operation. (Sometimes no air comes out during DRY operation.)

Fan speed does not match set fan speed during HEAT operation. (Sometimes no air comes out during HEAT operation.)

Air sometimes comes out when operation is stopped after HEAT operation.

This sound is made when internal parts of the unit expand or contract when the temperature changes. This is caused when the unit expels odours that have been absorbed from the walls, carpets, furniture or clothing. This may occur just after the unit is turned on when a high level of humidity is present in the room. This occurs to expel water or moisture that may have collected in the pipes or around piping fixtures. This occurs to dispel water from the heat exchanger.

Turn on the power switch “ “ will be displayed.

The start and stop function of the remote controller are not available when the CENTRALLY CONTROLLED indicator is displayed.

Wait about three minutes (operation has stopped to prevent damage to the air conditioner).

Not an error. During the DRY operation, blower ON/OFF is controlled by a microprocessor to prevent overcooling and to ensure efficient dehumidification. The fan speed can't be set by the remote controller during DRY operation.

Not an error.

1) When the HEAT operation starts, to prevent the unit from emitting cold air, the fan speed is gradually increased from zero to the set speed, in proportion to the temperature rise of the air emitted.

2) When the room temperature reaches the set temperature and the outdoor unit stops, the unit starts the LOW AIR operation.

3) During the HEAT operation, the DEFROST operation is performed to melt the frost adhering to the outdoor unit. During the DEFROST operation, the blower is stopped to prevent cold air coming from the indoor unit.

Not an error. The blower operates to eliminate the residual heat in the heated air conditioner. It stops after about 1 minute. This operation is performed when operation is stopped with the electric heater ON.

Solution Problem Solution

Is this timer on? Press the start/stop button to stop the unit. Was a distant commend sent from the remote controller? Find out if the remote controller was used. Is the CENTRALLY CONTROLLED indicator displayed? Find out if the remote controller was used. Is the automatic (cooling/heating) mode selected? Press the start/ stop button to stop the unit. Is the timer on? Press the start/stop button to restart the unit. Was a distant command sent from the remote controller? Find out if the remote controller was used. Is the CENTRALLY CONTROLLED indicator displayed? Find out if the remote controller was used. Set the schedule timer if one is connected. An automatic startup test is being performed (will last for about 2 minutes).

Indicates that it is time to clean the air filter. Clean the air filter. Press the FILTER button on the remote controller twice to make the display disappear. See the instruction manual that came with the product for how to clean the filter.

Displayed when the unit starts HEAT operation, when the air conditioning function puts the compressor in operation mode, or when the outdoor unit ends DEFROST operation and returns to HEAT operation. The display disappears after about 10 minutes. "STAND BY" displayed on the remote controller indicates that the indoor unit's heat exchanger hasn't fully heated up, so the blower air volume is restricted. To prevent cold air from being felt at this time, the up/down vane is automatically set to horizontal blow. When "STAND BY" is released, the up/ down vane returns to the setting specified by the remote controller.

"DEFROST" is displayed (no air comes out the unit).

An error code is displayed in the remote controller.

No display appears on the wireless remote controller. Signals are not received by the thin sensor unless sent from close up.

The operating display of the wireless remote controller`s receiver is flashing.

Frost adheres to the outdoor unit when the outside air temperature is low and the humidity is high. This display indicates that the DEFROST operation is being performed to melt this frost. The DEFROST operation ends after about 10 minutes (15 minutes maximum). During the DEFROST operation, the indoor unit's heat exchanger becomes cold, so the blower is stopped. The up/down vane is automatically set to horizontal blow. When the DEFROST operation ends, the unit switches to the HEAT SETUP operation.

A self-diagnostic function is being performed to preserve the air conditioner. * Do not attempt to make repairs

yourself. Turn the main switch off and contact the dealer from whom you bought the air conditioner. Provide him or her with the name of the unit and the information displayed in the remote controller.

The batteries are becoming weak. Replace the batteries and press the reset button. * If the display does not appear

NOTE: After a power cut, the unit will not restart automatically. You will have to restart it by pressing the POWER - ON/OFF button

on the remote controller.

If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the nature of the problem. Do not try to fix the unit yourself.

In any of the following cases, turn off the main power switch and contact your local dealer for service:

• The operation lamp (on the main unit) flashes.

• The switches do not work properly.

• The circuit breaker trips frequently (or the fuse blows frequently).

• Water has accidentally been splashed into the unit.

• Water leaks from the unit.

• Something is accidentally dropped into the air-conditioner.

• An unusual noise is heard during operation.

The following do not indicate any malfunction:

· Odours : Smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit.

· Sound of liquid flowing inside indoor unit : This can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit.

· Ticking sound coming from indoor unit : This can occur when cooling or heating has just begun or has just stopped. It is caused by the indoor unit shrinking or expanding slightly due to the change in temperature.

· The CENTRALLY CONTROLLED indicator appearing on the LCD panel : From time to time, this message may come up on the LCD panel. This does not indicate any malfunction.

Liquid-crystal display indicates that the unit operates.

A door or window has been open. Unit is waiting 3 minutes before restarting.

Clean the filter and resume operation.

Remove the obstruction.

Shut door or window. Wait until the unit restarts automatically. The compressor may hesitate resuming because a 3-minute resume prevention circuit is incorporated in the outdoor unit for protection of the compressor.

The output pulse shifts in above order.

* 1. When linear expansion valve operation stops, all output phase

become OFF.

* When the switch is turned on, 700 pulse closing valve signal will

be sent till it goes to A point in order to define the valve position.

(The pulse signal is being sent for about 20 seconds.)

When the valve moves smoothly, there is no noise or vibration

occurring from the linear expansion valve ; however, when the pulse number moves from B to A or when the valve is locked,

more noise can be heard than normal situation. No noise is heard when the pulse number moves from B to A in case coil is burn out or motor is locked by open-phase.

* Noise can be detected by placing the ear against the screw driv-

er handle while putting the screw driver to the linear expansion

valve.

(3) How to attach and detach the coil of linear expansion valve

<Composition> Linear expansion valve is separable into the main body and the coil as shown in the diagram below.

Stopper

Coil

Lead wire

Hold the lower part of the main body (shown as A) firmly so that the main body does not move and detach the coil by pulling it upward. Be sure to detach the coil holding main body firmly. Otherwise pipes can bend due to pressure.

Main bod

Hold the lower part of the main body (shown as A) firmly so that the main body does not move and attach the coil by inserting it downward into the main body. Then securely attach the coil stopper to main body. (At this time, be careful that stress is not added to lead wire and main body is not wound by lead wire.) If the stopper is not firmly attached to main body, coil may be detached from the main body and that can cause defective operation of linear expansion valve. To prevent piping stress, be sure to attach the coil holding the main body of linear expansion valve firmly. Otherwise pipe may break.

A

Be sure to attach the stopper.
