3 SAFETY PRECAUTION

3-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

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

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.

Handle 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.

The refrigerant oil applied to flare and flange connections must be ester oil, ether oil or alkylbenzene oil in a small amount.

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

Use the specified refrigerant only.

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of. Correct refrigerant is specified in the manuals and on the spec labels provided with our products. We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to follow the instructions.

3-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuits must disconnected.

[3] Service tools

Use the below service tools as exclusive tools for R410A refrigerant.

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 times 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.)

[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.)

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 refrigerants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A has been specified separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also has 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.

CHARGELESS SYSTEM PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT. (Max.30m)

The refrigerant circuit with LEV (Linear Expansion Valve) and accumulator always control the optimal refrigerant level regardless of the length (30m max. and 5m min.) of piping. The additional refrigerant charging work during installation often causes problems. Heretofore it is completely eliminated. This unique system improves the quality and reliability of the work done. It also helps to speed up the installation time.

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

2

shield 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) 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 earthing 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.

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.

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

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”.

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

(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,;/ 3 phase: L1,L2,L3,;) and the ground with a 500V Megger and check that it is 1.0M

or more. Do not operate the equipment if measurement is less than 1.0m . *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.

11-3. HOW TO PROCEED "SELF-DIAGNOSIS"

11-3-1. When a Problem Occurs During Operation

If a problem occurs in the air conditioner, the indoor and outdoor units will stop, and the problem is shown in the remote controller display.

[CHECK] and the refrigerant address are displayed on the temperature display, and the error code and unit number are displayed alternately as shown below.

 If the outdoor unit is malfunctioning, the unit number will be "00".

 In the case of group control, for which one remote controller controls

multiple refrigerant systems, the refrigerant address and error code of the unit that first experienced trouble (i.e., the unit that transmitted the error code) will be displayed.

 To clear the error code, press the

ON/OFF

button.

When using remote-/local-controller combined operation, cancel the error code after turning off remote operation. During central control by a MELANS controller, cancel the error code by pressing the

ON/OFF

button.

11-3-2. Self-Diagnosis During Maintenance or Service

Since each unit has a function that stores error codes, the latest check code can be recalled even if it is cancelled by the remote controller or power is shut off.

Check the error code history for each unit using the remote controller.



ing circuit is defective.

The remote controller must be replaced with a new one.

[Where the remote controller is not defective, but cannot be operated.] (Error display 2) [E3], [6833] or [6832] flashes.→ Transmission is not possible.

There might be noise or interference on the transmission path, or the indoor unit or other remote controllers are defective. Check the transmission path and other controllers.

(Error display 3)

"ERC" and the number of data errors are displayed. → Data error has occurred.

[for wired remote controller]

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

Problem Solution

The room neither gets cool nor warm very much.

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 does not blow air out right away in the heating mode.

The unit is preparing to deliver warm air.

The unit stops operating before arriving at the set temperature in the heating mode.

Frost forms when the outdoor temperature is low and humidity is high. Wait for about 10 minutes for the frost to melt.

The airflow direction suddenly changes.

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.

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

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.

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

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

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

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

Unit occasionally makes a gurgling sound.

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

Unit occasionally thuds. Not an error. This sound is emitted

when the air conditioner (outdoor unit) starts operating.

Outdoor unit occasionally rattles.

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

Problem Solution

A ticking noise is heard from inside of the unit.

This sound is made when internal parts of the unit expand or contract when the temperature changes.

An odour is detected in the room.

This is caused when the unit expels odours that have been absorbed from the walls, carpets, furniture or clothing.

A white mist is expelled from the indoor unit.

This may occur just after the unit is turned on when a high level of humidity is present in the room.

Water or moisture is expelled from the outdoor unit.

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.

The indicators of the remote controller do not light up when operated.

Turn on the power switch “ “ will be displayed.

CENTRALLY CONTROLLED indicator is displayed in the remote controller.

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

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

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

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

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.

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

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

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 Solution

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

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.

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

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.

The remote controller`s timer cannot be set.

Set the schedule timer if one is connected.

"FILTER" is displayed. 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.

"STAND BY" is displayed. 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.

Problem Solution

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

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.

An error code is displayed in the remote controller.

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.

A

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.

Be sure to attach the stopper.

A

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.
