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 piping 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.

Connect the cut-off lead wires with crimp contact, etc, put the closed end side upward and then apply a water-cut method, otherwise a leak or production of fire is caused at the users’ side.

When repairing the refrigerating cycle, take the following measures.

1) Be attentive to fire around the cycle. When using a gas stove, etc, be sure to put out fire before work; otherwise the oil mixed with refrigerant gas may catch fire.

2) Do not use a welder in the closed room. When using it without ventilation, carbon monoxide poisoning may be caused.

3) Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch the inflammables.

(For more details, please refer Page 7 to Page 9)

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

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 port 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 refrigerant with recovering device. The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as breakage or injury is caused.

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 electr ic 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 necessary that the density does not the limit even if the refrigerant leaks.

If the refrigerant leaks and exceeds the limit density, an accident of shor tage 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.

Put on gloves

Cooling check

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.

CAUTION

Be sure to put on gloves (

If not putting on gloves, an injury may be caused with the parts, etc. (∗) Heavy gloves such as work gloves

When the power was turned on, start to work after the equipment has been sufficiently cooled.

As temperature of the compressor pipes and others became high due to cooling/heating operation, a burn may be caused.

• New Refrigerant (R410A)

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 e xclusive to R410A, shapes of all the joints including the service port differ from those of the

former refrigerant in order to prev ent 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 refriger ant. Therefore use liquid type to charge the refrigerant. (If using gas for charging, composition of the refrigerant changes and then characteristics of the air conditioner 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.

4. Tools

(1)Required T ools for R410A

Mixing of different types of oil ma y cause 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 conventional refrigerant (R22))

2) Tools exclusive for R410A, but can be also used for conv entional 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.

R410A refrigerant is consisted with HFC mixed refrigerant. Therefore if the refrigerant gas is charged, the composition of the charged refrigerant changes and characteristics of the equipment changes.

6. Environmental concern

Use “Vacuum pump method” for an air purge (Discharge of air in the connecting pipe) in installation time.

• Do not discharge flon gas into the air to protect the earth environment.

• Using the vacuum pump method, clear the remaining air (Nitrogen, etc.) in the unit. If the air remains , the

pressure in the refrigerating cycle becomes abnormally high and an injury could occur through failure of the product.

3-9. Adjustment of Wind Direction

To increase the cooling or heating effect, be sure to use the discharge louver in different directions when in cooling or heating operation.

The characteristics of air are such that cold air will accumulate in the lower half of the room, while hot air will accumulate in the upper half.

Set the louver horizontally in cooling operation.

If a cooling operation is performed with a downwards discharge, the surface of the discharge port or louver will become wet with dew, and water may drip down.

• If a heating operation is performed with a horizontal discharge, unevenness the room temperature may not be equal i.e. there may be a large variance between one side of the room with the other.

4-way Air Discharge Cassette Type

• When the air conditioner is not in operation, the discharge louver will automatically directs downwards.

• When the air conditioner is in ready status for heating, the discharge louver will be directed upwards. The swinging operation will begin after heating ready status has been cleared. Please note the “SWING symbol will still be displayed on the remote controller even when the unit status is ready to begin the heating operation.

3-13. Air Conditioner Operations and Performance

Check before operation

• Check whether earth wire is disconnected or out of place.

• Check that air filter is installed to the indoor unit.

Heating capacity (for Heat-pump model only)

• During heating operation the heat pump system operates by absorbing the heat from the outside air and discharging it into the room. Therefore if the outside temperature drops, the units heating capacity will decrease.

• When temperature of the outside air is low, it is recommended that you use other forms of heating in conjunction with the air conditioner.

Turn on the power supply 12 hours or more before starting the air conditioner.

Defrost operation during heating operation (for Heat-pump model only)

• If the outdoor unit has a build up of frost during the heating operation, the operation mode changes automatically to defrost mode to increase the heating effect (for approximately 2 to 10 minutes).

• During defrost operation, fans of the indoor and the outdoor units will stop.

Protection for 3 minutes

• The outdoor unit will not operate for approximately 3 minutes after the air conditioner has been immediately restarted after being stop, or the power supply has been turned on. This is to protect the system.

Main power failure

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

• When restarting the unit, push the ON/OF F button again.

Fan rotation of stopped unit

• When other indoor units within the same system are in operation, the fan on the indoor units that are on “standby” will rotate to protect the machine once approximately 1 hour for several minutes.

Protective device (High pressure switch)

The high pressure switch operates the unit automatically when excessive load is applied to the air conditioner. If the protective device operates, the operation lamp will stay but the operation will stop. When the protective device operates, check characters “

The protective device may operate in the following cases.

” on the remote controller display.

In Cooling operation

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

• When strong winds blow continuously against the discharge port of the outdoor unit.

In Heating operation (For Heat-pump model only)

• When excessive dirt or dust is adhered to the air filter of the indoor unit.

• When the discharge port of the indoor unit is blocked.

Cooling/heating operation of MiNi-SMMS air conditioner

In MiNi-SMMS air conditioner, each indoor unit can be individually controlled. However, cooling operation and heating operation cannot be performed concurrently for the indoor units, which are connected to the same outdoor unit.

When cooling operation and heating operation are performed concurrently, the indoor unit which is performing cooling operation stops, and the “ continue operation.

If the manager has fixed the setting to COOL or HEAT, no other operation can be performed. When another operation other than the set up one is performed, the “

the indoor unit.

” on the unit display will be lit. The indoor unit that is in heating mode will

” light is displayed on the display part of

Characteristics of heating operation (For Heat-pump model only)

• Hot air will not be blown out immediately from the indoor unit. It will take between 3 to 5 minutes (depending on temperature conditions of the room and the outside) before the indoor heat exchanger warms up sufficiently, to allow hot air to be blown.

• During operation, the outdoor unit may stop if the outside temperature becomes to high.

• When other indoor units are in heating operation, the fan operation of the indoor unit on fan only operation may be stopped temporarily to prevent hot air from being blown out.

WARNING

It’s strange.

Silent

The slot provided at side surface of the outdoor unit is an air intake for cooling the electrical parts.

If the air intake would be clogged, a trouble is caused on the electrical parts. Therefore nev er close the air intake or do not place any obstacle near the air intake.

Outdoor temperature : –5°C to 43°C (Dry-bulb temp.)

Room temperature : 21°C to 32°C (Dry-bulb temp.), 15°C to 24°C (Wet-bulb temp.)

CAUTION

Outdoor temperature : –15°C to 15.5°C (Wet-bulb temp.)

Room temperature : 15°C to 28°C (Dry-bulb temp.)

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.

If air conditioner is used outside of the above conditions the units, safety protection devices may operate.

3-14. Re-Installation

DANGER

If the unit position is to be changed and re-located to a new position ask your local dealer or installation specialist. Do not attempt to move the air conditioner yourself, as incorrect installation 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 places, noise transmitted from the air conditioner may effect the operation of these appliances.

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

• Do not install the air conditioner in a salty place such as a 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 winds such as in a seaside area or on the roof / upper floor of a building.

• Do not install the air conditioner in a place where sulfureous gas may be 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 the noise or the hot air created by the outdoor unit will come into contact with your neighbours.

• Install the air conditioner on a solid and stable foundation as this will reduce the transmission of noise and vibration that is produced from the outdoor unit.

• If one indoor unit is operating, some sound may be audible from other indoor units that are connected within the same system (even when not in operation).

• When the unit is in operation,a sound such as the movement of water from one area to another may be heard. This sound may become larger after a period of 2 to 3 minutes once the unit has begun operation. This is not a cause for concern, but is the movement of the refrigerant or the draining sound of the dehumidifier.

• When the air conditioner system is operating, the stopping indoor unit in the same system needs temporary flow of refrigerant to prevent the stay of oil or refrigerant.

Therefore, refrigerant flow sound “shaa/cyu” may be heard, or white vapor may come out when other indoor unit heating, or cool air may come out when other indoor unit cooling.

• This sound is generated when the heat exchanger, etc. expands and contracts slightly due to the change of temperature.

• V arious odurs such as those from a carpet, clothes, cigarette, or cosmetics will adhere to the air conditioner.

• When cooling operation cannot be performed because another indoor unit performs heating operation.

• When the manager of the air conditioner has fixed the operation to either COOL or HEAT, but a request or demand contrary to the setup operation is requested.

• When the fan operation is stopped to prevent the discharge of hot air.

• Sound is generated when the expansion valve operates when the power supply has been turned on.

• Is the timer “ON” or “OF F”?

• Is there a power failure to the unit?

• Has the power supply been turned off?

• Has the power fuse or breaker blown?

• Has the protective device operated? (The operation lamp goes on.)

• Is the timer “ON”? (The operation lamp goes on.)

Item

Operation explanation and applied data, etc.

(1) PMV control

• PMV is controlled between 45 to 500 pulses during

operation.

• In cooling operation, PMV opening is dependent upon

detected readings from the TL sensor and Pd pressure sensor (sub-cool control).

• In heating operation, PMV opening is dependent upon

detected readings from the TS and TD sensors and the Ps pressure sensor (super-heat control).

• PMV will be fully closed when the system is in ‘Standby’ or

‘No demand’ modes and when a malfunction in the system has occurred.

(1) Fan control in all cooling operation

1) The outdoor fan speed/mode is determined by the

detected Pd pressure value.

2) When cooling operation has star ted, the outdoor fan

speed of the master unit is controlled using the detected Pd pressure value.

(2) Fan control in all heating operation

1) The outdoor fan speed/mode is determined by the

detected TE sensor value.

2) If a TE value > 25°C has been continuously detected for 5

minutes, the operation may stop.

3) After star t up, this control is not available during the

specified time after a defrost operation.

4) This operation may start and stop repeatedly when the

system is undercharged.

(3) Fan control for mainly cooling, part heating operation

Operation explanation and applied data, etc.

(1) Defrost start condition

The defrost function is initiated when the measurement temperature taken from the TE sensor is lower than –1°C for a period of 25 minutes after compressor initial start up and 55 minutes after subsequent start ups.

(2) Contents of control

• If the outdoor units are combined, the minimum duration for the defrost operation is 2 minutes.

(3) Defrost stop condition

• The outdoor fan speed and compressor inverter frequency are determined by the measurement of Pd pressure during defrost operation.

(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 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 transient operation. This control is individually executed by the outdoor unit.

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

(4) SV4 low-pressure release control

This control is to prevent low-pressure dropping and is individually executed by unit.

Case heater control

IPDU control

Operation explanation and applied data, etc.

Heating is provided for both the compressor case and accumulator. When the compressor in any outdoor unit is stopped, the heater is switched on to prevent accumulation of refrigerant. After installation of a system, it should be powered for the specified period of time prior to operating a test run to prevent damage to the system.

If the system has not been powered for a prolonged period of time, it is important to apply power for the specified period of time before resuming operation.

This function is often performed in conjunction with the compressor winding heating control. When this occurs, a noise may be heard which is not an indication of a malfunction.

(1) Contents of control

• The function is performed during when the compressor is off.

• When the TO sensor temp measures 28°C or higher the heater turns off and turns on when it change:measures 25°C or lower

• The heater remains ‘ON’ for 10 minutes after the compressor

has changed mode from Off to On.

The IPDU controls the inverter compressor by communicating a command frequency that controls the compressor speed, depending on any active releases.

The main controls of the IPDU P.C. board are:

(1) Current release control

Feedback from the AC input current sensor (CT) is used to prevent the inverter input current exceeding its specified limit

(2) Heat sink temperature detection control

• Feedback from the thermistor (TH) on the compressor driving module is used to prevent the IGBT from overheating. The highest value is taken from IPDU TH sensors.

(3) Over-current protective control

• When an over-current condition is detected by the IPDU, the compressor is stopped.

(4) Compressor case thermo control

• The compressor stops when the compressor case thermostat is activated.

• Whenever this condition occurs, a 1 count is added to the system error count.

• After a period of 2 minutes and 30 seconds, the compressor is reactivated and the error count cleared if the operation continues without further error for a period of 10 minutes or more.

• If the error count reaches 4, the check code [H04] is displayed.

Remarks

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

High pressure prevention control

(1) High pressure SW control

• The high pressure switch is connected to the IPDU board and is in the normally closed condition.

• When the high pressure switch is activated, the compressor is stopped.

• Whenever this condition occurs, a 1 count is added to the system error count.

• After a period of 2 minutes and 30 seconds, the drive to the compressor is reactivated and the error count is cleared if the operation continues with further error for a period of 10 minutes or more.

• If the error count reaches 4, the check code [P04] is displayed.

Other cautions

1. Cooling operation in low ambient temperatures

1) The indoor unit freeze prevention control system (TC sensor) may decrease the command frequency to the outdoor unit when low coil temperatures are detected.

2) The cooling capacity control may decrease the command frequency to the outdoor unit when low ambient temperature is detected.

3) When the discharge temperature sensor value reaches 60°C or below, the frequency may be increased above the required demand from the indoor unit.

2. PMV (Pulse Motor Valve) for outdoor unit

1) When the system power is turned on an audible “clicking” sound is omitted due to the PMV initializing, this is a normal condition. When the outdoor unit is situated near other sources of noise, this sound may not be noticeable.

2) Do not remove the driving part (head) of the PMV during operation as it may cause the PMV to malfunction.

3) When transporting or replacing the outdoor unit, never keep the driving part (head) removed from the PMV body as the valve will be closed and ma y result in damage or failure due to sealed liquid compression.

4) When refitting the driving part (head) to the body of the PMV, apply pressure until a “click” sound can be heard, complete the process by resetting the power to the system.

8. PMV KIT OUT LINE

8-1. Purpose of Using

In the case of very quiet room, and also very nervous for indoor unit noise lev el, PMV Kit should be installed before indoor unit which should become lower noise level.

Multi-indoor units have Pulse Motor Valve (PMV) for control refrigerant flow. Multi-air conditioner, on unstable condition, for example starting time, flowing noise of refrigerant can be heard

conspicuously. This refrigerant noise mainly comes from PMV. Especially ve ry quiet room, for example bed room, somebody

feels uncomf ortable for this refrigerant noise from PMV. Main purpose of PMV Kit restrains refrigerant noise which comes from PMV installed in indoor unit.

PMV Kit should be installed at out of residence area, for e xample back of ceiling board. After installed PMV Kit, control function of refrigerant shifts to PMV of PMV Kit and PMV in indoor unit does not

be used. After that, refrigerant noise of PMV will be coming from back ceiling board, and refrigerant noise of indoor unit

may be restrained.

8-3. Effect of Connecting PMV Kit without Fully Opening of

Indoor Unit PMV

Effect of miss-installation which PMV of indoor unit was not fully opened (1500 pulse) are as follows. Following symptom occurred, PMV of indoor unit should be fully opened.

1. Cooling operation

1) Even though command of PMV is fully open (1500 pulse), actual SH is larger than aim SH.

2) Even though command of PMV is fully open (1500 pulse), cool air does not discharge.

3) Ps is abnormally low, or outdoor unit stops by Ps protection.

2. Heating operation

1) Even though command of PMV is fully open (1500 pulse), actual UC is larger than aim UC.

2) Even though command of PMV is fully open (1500 pulse), hot air does not discharge.

3) Pd is abnormally high, or outdoor unit stops by Pd protection.

8-4. How to Fully Open PMV of Indoor Unit

1. Stop indoor and outdoor units operation and turn off power supply to each units.

2. Remove connection cable of PMV Kit from P.C. board of indoor unit and connect PMV of indoor unit to P.C. board.
