IMPORTANT! Please Read Before Starting

This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.

For safe installation and trouble-free operation, you must:

●

Carefully read this instruction booklet before beginning.

●

Follow each installation or repair step exactly as shown.

●

Observe all local, state, and national electrical codes.

●

Pay close attention to all warning and caution notices given in this manual.

This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.

This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage.

If Necessary, Get Help

These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.

SPECIAL PRECAUTIONS

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.

• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death.

• Ground the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire

hazard.

When Transporting

Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.

When Installing…

…In a Ceiling or Wall

Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.

…In a Room

Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.

…In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration.

…In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.

…In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

• Use the flare method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leakfree connection.

• Check carefully for leaks before starting the test run.

When Servicing

• Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.

• Keep your fingers and clothing away from any moving parts.

• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.

Others

• Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.

• Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.

Insulation of Refrigerant Tubing

IMPORTANT

Because capillary tubing is used in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. To prevent heat loss and wet floors due to dripping of

condensation, both tubes must be well insulated with a

proper insulation material. The thickness of the insulation should be a min. 8 mm.

After a tube has been insulated,

CAUTION

never try to bend it into a narrow curve because it can cause the tube to break or crack.

NOTE

• The fan speed is forcibly changed to “LL” beginning 30 seconds after the thermostat turns OFF.

• Normal operation refers to operation when the room temperature has approached the set temperature.

• When HEAT operation starts, the indoor fan is stopped until the

temperature of the indoor heat exchanger reaches 20°C or higher, or until the room temperature reaches 15°C or higher.

This function controls the operation frequency to prevent the compressor discharge temperature from rising more than a specified temperature.

Area: Automatic capacity control.

When the temperature rises above Point A, the operation frequency is reduced at a specified rate.

Area: Further frequency increase is prohibited.

When the temperature falls below Point B, prevention of a rise in frequency is released and the air conditioner operates as in

area.

The compressor will stop if the temperature of the compressor

discharge exceeds 120°C due to shortage of gas or other

reason.

■ Defrost detection and release

• This function prevents the circuit breaker or fuse from operating to open the circuit. This function works when electrical current has increased due to an increase in the cooling / heating load, or to a decrease in the power supply voltage. In these cases, operation frequency is reduced or operation is interrupted automatically to control the electrical current for operation.

• When the cause of the increase in electrical current is rectified, the system will resume operation in the original mode.

10. TROUBLESHOOTING

■ Precautions before performing inspection or repair

NOTE

Executing self-diagnostics

● After checking the self-diagnostics monitor, turn the power OFF before starting inspection or repair.

● High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge

(charging voltage DC 310 V) even after the power is turned OFF, and some time is required for the charge to dissipate. Be careful not to touch any electrified parts before the controller LED (red) turns OFF.

If the outdoor controller is normal, approximately 30 seconds will be required for the charge to dissipate. However, allow at least 5 minutes for the charge to dissipate if there is thought to be any trouble with the outdoor controller.

1: If the operation lamp blinks every 0.5 seconds immediately when the power

is turned ON, there is an external ROM (OTP data) failure on the indoor circuit board, or a ROM socket insertion problem, or the ROM has not been installed.

2: The failure mode is stored in memory even when the power is not ON.

Follow the procedure below to perform diagnostics.

“oP-1” to “oP-3” (self-diagnostics). (The display continues to blink.)

Step 3: Finally press the ON/OFF button to engage self-diagnostics mode.

• The self-diagnostics function utilizes the 3 indicator lamps on the main unit, in combinations of ON lamps, blinking lamps, and OFF lamps, to report the existence of sensor trouble or a protective operation. (The lamps blink or remain ON for 5 seconds, then turn OFF for 2 seconds.) Self-diagnostics is completed when the buzzer sounds 3 short beeps.

• A maximum of 3 self-diagnostics reports are displayed, for 5 seconds each, beginning with the most recent report. Following this display the lamps turn OFF. In order to view the self-diagnostics results again, press the ON/OFF button again.

• The 3 lamps remain OFF if no trouble has occurred.

<IMPORTANT> After self-diagnostics is completed, be sure to press the ACL

(reset) button to return to normal mode. The air conditioner will not operate if this is not done.

After turning on power to the air conditioner, use the remote controller and follow the steps below to execute self-diagnostics.

●

This outdoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil resistance, and the following procedure should be used to check the motor.

●

To perform diagnosis, follow the instructions in “Checking the Outdoor Unit” on the previous page and set the outdoor unit to Test Run mode (compressor ON, outdoor fan motor ON).

Important: (A) Turn OFF the power before connecting or disconnecting the motor connectors.

(B) When performing voltage measurement at the outdoor controller connector for (3) in the table

below, the DC motor will trip and voltage output will stop approximately 10 seconds after operation is started. For this reason, to measure the voltage again, first turn OFF the outdoor unit power, then follow the instructions in “Checking the Outdoor Unit” and again set the unit to Test Run mode.

[Trouble symptom 1] The fan does not stop when the outdoor unit stops.

→

Outdoor unit controller trouble

[Trouble symptom 2] The fan motor does not rotate when the outdoor unit is operating.

(Diagnostic procedure)

* Disconnect the motor connectors and measure the voltage at the DC motor connectors on the outdoor

unit controller (3 locations).

Measurement location Normal value

(1) Vs-Gnd: Between pin 1 and pin 4 DC 230 V or more

(2) Vcc-Gnd: Between pin 5 and pin 4 DC 14 V or more

(3) Vsp-Gnd: Between pin 7 and pin 4 After fluctuating 4 times between DC 1.0 – 4.3 V

(1 sec. ON) and DC 0 V (1 sec. OFF), the DC motor trips.

(Diagnostic results)

All of the above measured values are normal. →Fan motor trouble (Replace the motor.)

Any one of the above measured values is not normal. →Outdoor unit controller trouble

(Replace the controller .)

[Trouble symptom 3] Motor rotates for some time (several seconds), but then quickly stops, when the outdoor

unit operates. (There is trouble in the system that provides feedback of motor rotation speed from the motor to the outdoor unit controller.)

[Trouble symptom 4] Fan motor rotation speed does not change during outdoor unit operation.

[Trouble symptom 5] Fan motor rotation speed varies excessively during outdoor unit operation.

(Remedy for symptom 3 to 5)

It is not possible to identify whether the trouble is outdoor unit controller trouble or motor trouble. Therefore, first replace the outdoor unit controller, then (if necessary) replace the DC motor.

An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices.

A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these effects may still occur. Please pay attention to the points listed below.

■ Noise malfunction

This refers to the application of high-frequency noise to the signal wires, resulting in abnormal signal pulses and malfunction.

Locations most susceptible to noise

1. Locations near broadcast stations where there are strong electromagnetic waves

2. Locations near amateur radio (short wave) stations

3. Locations near electronic sewing machines and arc-welding machines

Correction

(The fundamental concept is to make the

system less susceptible to noise.)

— Insulate for noise or

distance from the noise source. —

1. Use shielded wires.

2. Move unit away from the noise source.

Trouble

Either of the following trouble may occur.

1. The unit may stop suddenly during operation.

2. Indicator lamps may flicker.

■ Electromagnetic interference

This refers to noise generated by high-speed switching of the microcomputer and compressor. This noise radiates through space and returns to the electric wiring, affecting any wireless devices (televisions, radios, etc.) located nearby.

Locations most susceptible to noise

1. A television or radio is located near the A/C and A/C wiring.

2. The antenna cable for a television or radio is located close to the A/C and A/C wiring.

3. Locations where television and radio signals are weak.

Correction

1. Select a separate power source.

2. Keep the A/C and A/C wiring at least 1 meter away from wireless devices and antenna cables.

3. Change the wireless device’s antenna to a highsensitivity antenna.

4. Change the antenna cable to a BS coaxial cable.

5. Use a noise filter (for the wireless device).

6. Use a signal booster.

Trouble

1. Noise appears in the television picture, or the picture is distorted.

2. Static occurs in the radio sound.

11-1. Measurement of Insulation

Resistance

●

The insulation is in good condition if the resistance

exceeds 1MΩ.

11-1-1. Power supply cord

Clamp the grounding wire of power cord with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the two power wires. (Fig. 1)

Then also measure the resistance between the grounding and other power terminals. (Fig. 1)

11-1-2. Indoor unit

Clamp an aluminum plate fin or copper tube with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on each terminal screw where power supply lines are connected on the terminal plate. (Fig. 2)

11-1-3. Outdoor unit

Clamp an aluminum plate fin or copper tube with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on each terminal screw on the terminal plate. (Fig. 2)

Note that the ground line terminal should be skipped for the check.

11-1-4. Measurement of insulation

resistance for electrical parts

Disconnect the lead wires of the desired electric part from terminal plate, capacitor, etc. Similarly disconnect the connector. Then measure the insulation resistance. (Figs. 3 and 4)

Refer to Electric Wiring Diagram.

If the probe cannot enter the poles because the hole is too narrow then use a probe with a thinner pin.

12. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SERVICING UNIT

12-1. Characteristics of New Refrigerant R410A

12-1-1. What is New Refrigerant R410A?

R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22.

12-1-2. Components (mixing proportions)

HFC32 (50%) / HFC125 (50%)

12-1-3. Characteristics

●

Less toxic, more chemically stable refrigerant

●

The composition of refrigerant R410A changes whether it is in a gaseous phase or liquid phase. Thus, when there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in composition of the remaining refrigerant.

Therefore, do not add new refrigerant.

Instead, recover the remaining refrigerant with the refrigerant recovery unit. Then, after evacuation, totally recharge the specified amount of refrigerant with the new refrigerant at its normal mixed composition state (in liquid phase).

●

When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or liquid phase, and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in gaseous state.

Thus, always charge the refrigerant while it is in liquid phase.

12-2. Checklist Before Servicing

Use a clutch-type flare tool for R410A or the conventional flare tool. Note that sizes of the resultant flares differ between these two tools. Where a conventional flare tool is used, make sure to observe A Specification (amount of extrusion) by using the flare spacer.

●

Size of flare

Ether-type oil is used for compressor oil for R410A-type units, which is different from the mineral oil used for R22. Thus more attention to moisture prevention and faster replacement work compared with conventional models are required.

●

Tubing precautions

Refrigerant R410A is more easily affected by dust or moisture compared with R22, thus be sure to temporarily cover the ends of the tubing with caps or tape prior to installation.

Never use 0.7mm-thick copper tubing or tubing which is less than 0.8mm in thickness, since air conditioners with R410A are subject to higher pressure than those using R22 and R407C.

●

No addition of compressor oil for R410A

No additional charge of compressor oil is permitted.

●

No use of refrigerant other than R410A

Never use a refrigerant other than R410A.

●

If refrigerant R410A is exposed to fire

Through welding, etc., toxic gas may be released when R410A refrigerant is exposed to fire. Therefore, be sure to provide ample ventilation during installation work.

●

Caution in case of R410A leak

Check for possible leak points with the special leak detector for R410A. If a leak occurs inside the room, immediately provide thorough ventilation.

12-3. Tools Specifically for R410A

●

For servicing, use the following tools for R410A

●

To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, sizes of the service ports and flare nuts of the narrow tube service valve and wide tube service valve have been altered.

12-4. Tubing Installation Procedures

When the tubes are connected,

always apply HAB oil on the flare portions to improve the sealing of tubing.

The following is the HAB oil generally used:

Esso: ZERICE S32

For details on tubing installation procedures, refer to the installation manuals attached to the indoor unit and outdoor unit.

Tools specifically for R410A

Tools which can be commonly used for R22, R407C, and R410A

●

The above tools specifically for R410A must not be used for R22 and R407C. Doing so will cause malfunction of the unit.

●

For the above vacuum pump (*1, *2) and vacuum pump adapter (*3), those for R22-type units can be used for R407C-type. However, they must be used exclusively for R410A and never alternately with R22 and R407C.

CAUTION

12-5. In Case of Compressor Malfunction

12-5-1. Procedure for replacing compressor

(1) Recovering refrigerant

● Any remaining refrigerant inside the unit should not be

released to the atmosphere, but recovered using the refrigerant recovery unit for R410A.

● Do not reuse the recovered refrigerant, since it will

contain impurities.

(2) Replacing Compressor

● Soon after removing seals of both discharge and suc-

tion tubes of the new compressor, replace it quickly.

(3) Checking for sealing

● Use nitrogen gas for the pressurized gas, and never

use a refrigerant other than R410A. Also do not use oxygen or any flammable gas.

(4) Evacuation

●

Use a solenoid valve-installed vacuum pump

so that even if power is cut off in the middle of evacuation of air due to a power interruption, the valve will prevent the pump oil from flowing back.

● The equipment may be damaged if moisture remains

in the tubing, thus carry out the evacuation thoroughly.

● When using a vacuum pump with exhaust air volume

more than 25L/min. and ultimate vacuum pressure rate of 0.05Torr:

Standard time for evacuation

●

Should the compressor malfunction, be sure to make the switch to a replacement compressor as quickly as possible.

●

Use only the tools indicated exclusively for R410A. ➞See “12-3. Tools Specifically for R410A.”

CAUTION

(1) Recover refrigerant

(2) Replace compressor

(3) Check for sealing

(4) Evacuation

(5) Recharge

(5) Recharging

●

Be sure to charge the specified amount of refrigerant in liquid state

using the service port of the wide tube service valve. The proper amount is listed on the unit's nameplate.

When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.

● When charging with a refrigerant cylinder, use

an electronic scale for charging refrigerant. In this case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change. Thus,

do not use the refrigerant if the amount in the charging cylinder is less than 20%.

Also, charge the minimum necessary amount to the charging cylinder before using it to charge the air conditioning unit.

Example:

In case of charging refrigerant to a unit requiring

0.76Kg using a capacity of a 10Kg cylinder, the minimum necessary amount for the cylinder is:

0.76 + 10 × 0.20 = 2.76Kg

For the remaining refrigerant, refer to the instructions of the refrigerant manufacturer.

● If using a charging cylinder, transfer the speci-

fied amount of liquid refrigerant from the refrigerant cylinder to the charging cylinder.

Prepare an evacuated charging cylinder beforehand.

Do not use the refrigerant if the amount in the charging cylinder is less than 20%.

Never charge a large amount of liquid refrigerant at once to the unit. This may cause damage to the compressor.

●

To prevent the composition of R410A from changing, never bleed the refrigerant gas into the atmosphere while transferring the refrigerant. (Fig. 3)

12-6. In Case Refrigerant is Leaking

(1) Detecting Leaks

● Use the detector for R410A to locate refrigerant leak

points.

(2) Recovering refrigerant

● Never release the gas to the atmosphere; recover

residual refrigerant using the refrigerant recovery unit for R410A, instead.

● Do not reuse the recovered refrigerant because its

composition will have been altered.

(3) Welding leaking points

● Confirm again that no residual refrigerant exists in the

unit before starting welding.

● Weld securely using flux and wax for R410A.

● Prevent oxide film from forming inside the tubes utiliz-

ing substitution with nitrogen (N2) in the refrigerant circuit of the unit. Leave ends of tubes open during welding.

(4) Checking for sealing

● Use nitrogen gas for the pressurized gas, and never

use a refrigerant other than R410A. Also do not use oxygen or any flammable gas.

(5) Evacuation

●

Use a solenoid valve-installed vacuum pump

so that even if power is cut off in the middle of evacuation of air due to a power interruption, the valve will prevent the pump oil from flowing back.

● The equipment may be damaged if moisture remains

in the tubing, thus carry out the evacuation thoroughly.

● When using a vacuum pump with exhaust air volume

more than 25L/min. and ultimate vacuum pressure rate of 0.05Torr:

Standard time for evacuation

(6) Recharging

● Recharge unit in the same manner explained on the

previous page “(5) Recharging.”

Never attempt to charge additional refrigerant when refrigerant has been leaking from the unit. Follow the procedure described below to locate points of leaks and carry out repairs, then recharge the refrigerant.

12-7. Charging Additional Refrigerant

12-7-1. When Tubes are Extended

●

Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came with the indoor unit.

Charge additional refrigerant in liquid state only.

12-8. Retro-Fitting Existing Systems

12-8-1. Use of Existing Units

●

Never use new refrigerant R410A for existing units which use R22.

This will cause the air conditioner to

operate improperly and may result in a hazardous condition.

12-8-2. Use of Existing Tubing

●

If replacing an older unit that used refrigerant R22 with a R410A unit,

do not use its existing tubing.

Instead,

completely new tubing must be used.

Never charge additional refrigerant if refrigerant is leaking from the unit. Follow instructions given in “12-6. In Case Refrigerant is Leaking” and completely carry out repairs. Only then should you recharge the refrigerant.

‘‘DRY’’ ( ) Operation

How it works? • Once the room temperature reaches the level that was set, the unit’s

operation frequency is changed automatically.

• During DRY operation, the fan speed is automatically runs at lower speed for providing a comfortable breeze.

• ‘‘DRY’’ operation is not possible if the indoor temperature is 15 °C or less.

Heating ( ) Operation

Heating performance • Because this air conditioner heats a room by drawing in the heat of the

outside air (heat pump system), the heating efficiency will fall off when the outdoor temperature is very low. If sufficient heat cannot be obtained with this air conditioner, use another heating appliance together with it.

Defrosting • When the outdoor temperature is low, frost or ice may form on the heat

exchanger coil, reducing heating performance. When this happens, a microcomputer defrosting system operates. At the same time, the fan on the indoor unit stops and the OPERATION lamp lights up red and orange alternately until defrosting is completed. Heating operation restarts after several minutes. (This interval will vary slightly depending upon the outdoor temperature and the way in which frost forms.)

Cold draft prevention • For several minutes after the start of heating operation, the indoor fan runs

• In the event of power failure, the unit will stop. When the power is resumed, the unit will restart automatically within five minutes by the remote control unit.

• In heating or cooling operation, any plastic parts may expand or shrink due to a sudden temperature change. In this event, a clicking sound may occur. This is normal, and the sound will soon disappear.

• The remote control unit sends the setting condition to the air conditioner regularly at five minute intervals.
