Do not use the existing refrigerant piping.

The old refrigerant and lubricant in the existing piping contains a large amount of chlorine which may cause the lubricant deterioration of the new unit.

Use “low residual oil piping”

If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricant will result.

Use ESTER , ETHER or HAB as the lubricant to coat flares and flange connection parts.

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

Use liquid refrigerant to charge the system.

If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop.

Do not use a refrigerant other than R407C.

If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricant deterioration.

Use a vacuum pump with a reverse flow check valve.

The vacuum pump oil may flow back into the refrigerant cycle and cause the lubricant deterioration.

Store the piping to be used during installation indoors with keep both ends sealed until just before brazing. (Store elbows and other joints in a plastic bag.)

If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.

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

CHARGELESS SYSTEM PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT.

PU/PUH-P25, P35, P50, P60 : max 20m PU/PUH-P71, P100, P125, P140 : max 30m

The refrigerant circuit with LEV(Linear Expansion Valve) and a large accumulator always control the optimal refrigerant

level regardless of the length (20/30m 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.

Be sure to connect the indoor-outdoor connecting cables directly to the units (no intermediate connections). Intermediate connections can lead to communication errors if water enters the cables and causes insufficient insulation to ground or a poor electrical contact at the intermediate connection point. (If an intermediate connection is necessary, be sure to take measures to prevent water from entering the cables.)

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

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

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.

(Excluding the case connecting to system controller.)

(2) Connect the wire to the M-NET terminal block.Connect one core of the

transmission wire (non-polar) to Aterminal and the other to B. Peel the shield wire, twist the shield part to a string and connect it to S terminal.

(3) In the system which several outdoor units are being connected, the terminal

(A, B, S) on M-NET terminal block should be individually wired to the other

shield wire for electric wires.

8-3-1. 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”.)

8-3-2. 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”.)]

8-3-3. 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”.

10-1. TROUBLESHOOTING

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.

10-2. 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 Merger and check that it is 1.0M" or over.

wDon’t use 500V Merger 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 twelve 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 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 for correct motion of auto-vanes.

Cooling mode:

Check if cool air blows and water is drained. Heating mode: Check if warm air blows. (It takes a little while until warm air blows.)

The TEST RUN appears on the screen.

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 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.

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 rebris that collects 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 one 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.

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 two 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
