3 SAFETY PRECAUTION

Use new refrigerant 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.

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

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

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.

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.

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.

Keep the tools with care.

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

Do not use a charging cylinder.

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

Tools for R410A

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

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

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

Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

3-1. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

[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.)

: Prepare a new tool. (Use the new tool as the tool exclusive for R410A.) : Tools for other refrigerants can be used under certain conditions. : Tools for other refrigerants can be used.

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 specified 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.

Good example 2 (Single spot grounding of shield wire)

(Points to notice) (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 1.25mm2shield wire (CVVS, CPEVS) for the transmission wire. Transmission signals may not be sent or

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) Ground 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 grounding spots on the shield wire, noise may enter into the shield wire because the ground wire and shield wire form one circuit and the electric potential difference occurs due to the impedance difference among grounding spots. In case of single spot grounding, noise does not enter into the shield wire because the ground wire and shield wire do not form one circuit.

To avoid communication errors caused by noise, make sure to observe the single spot grounding method described in the installation manual.

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 Free Combo 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 Free Combo 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. (Factory 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. [Factory setting: all switches are OFF. (All refrigerant addresses are “00”.)]

9-4-3. Regulations in address settings

In case of multiple grouping system, M-NET and refrigerant address settings should be done as explained in the above section. Set the lowest number in the group for the outdoor unit whose refrigerant address is “00” as its M-NET address.

w Refrigerant addresses can be overlapped if they are in the different group.

w In group B, M-NET address of the outdoor unit whose refrigerant address is “00” is not set to the minimum in the group. As

“3” is right for this situation, the setting is wrong. Taking group A as a good sample, set the minimum M-NET address in the group for the outdoor unit whose refrigerant address is “00”.

Present and past error codes are logged and displayed on the wired remote controller and control board of outdoor unit. Actions to be taken for service, which depends on whether or not the inferior phenomenon is reoccurring at service, are summarized in the table below. Check the contents below before investigating details.

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.

wDon’t 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 “Selection of Functions through Remote Controller”.

Make sure to read operation manual before test run. (Especially items to secure safety.)

The TEST RUN appears on the screen. Cooling mode:

Heating mode: Check if warm air blows. (It takes a little while until warm air blows.)

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.

(2) Outdoor Unit

1) Check Items

• After installation of indoor and outdoor units, and tubing and electric wiring work, check that the unit is free from leaks of refrigerant, loosened connections, and incorrect polarity.

• Check that there is no negative phase and open phase. (The F1 message for negative phase and the F2 message for open phase will flash at digital indicator LED 1 on the outdoor substrate. If this happens, rewire correctly.)

• Measure the impedance between power terminals (Single phase: L,N,;;/ triple phase: L1,L2,L3,;;) and the ground with a 500V Megger and check that it is 1.0MΩ or more. Do not operate the equipment if measurement is less than 1.0mΩ. *Never conduct this operation on the out- door connection wiring terminals (S1,S2,S3) as this causes damage.

• When there is no error at the outdoor unit. (If there is an error at the outdoor unit, it can be evaluated at LED 1 [digital display] of the outdoor substrate.)

• The stop valves are open both the liquid and gas sides. After checking the above, execute the test run in accordance with the following.

2) Test run start and finish

• Operation from the indoor unit Execute the test run using the installation manual for the indoor unit.

• Operation from the outdoor unit. Execute settings for test run start, finish and operation mode (cooling, heating) using the DIP switch SW 4 on the outdoor substrate.

1 Set the operation mode (cooling, heating) using SW4-2. 2 Turn ON SW 4-1, The operation mode for SW 4-2 will be adhered to, and the test run will commence. 3 Turn OFF SW 4-1 to finish the test run.

• There may be a faint knocking noise emitted from the proximity of the fan during the test run. This is torque fluctuation occurring due to control of fan revolutions. There is no problem with the product.

Note: The SW 4-2 operation mode cannot be changed during the test run. (To change run mode, stop the equipment with SW 4-1, change the operation mode, then restart test run with SW 4-1.)

2 Defective transmitting receiv-

ing 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.

[for wired remote controller]

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

Problem The room neither gets cool nor 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 doesn't 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 doesn't 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 doesn't match set fan speed during DRY operation. (Sometimes no air comes out during DRY operation.)

Fan speed doesn't 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.

Problem The unit started even though the start/stop button was not pushed.

The unit stopped even though the start/stop button was not pushed.

The remote controller`s timer cannot be set. “PLEASE WAIT” is displayed in the remote controller.

"FILTER" is displayed.

"STAND BY" is displayed.

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

after replacing the batteries, make sure that the (+,–) cells are aligned correctly.

(1) Operation summary of the linear expansion valve

• Linear expansion valve open/close through stepping motor after receiving the pulse signal from the outdoor controller board.

• Valve position can be changed in proportion to the number of pulse signal. <Connection between the indoor controller board and the linear expansion valve>

(2) Linear expansion valve operation

Opening a valve : 8 → 7 → 6 → 5 → 4 → 3 → 2 → 1 → 8 Closing a valve : 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 1

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 dri-

ver 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 body

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.

Be sure to attach the stopper.
