1. Safety Considerations

IMPORTANT!

Please Read Before Starting

This air conditioning system meets strict safety and operating standards. As the installer or service person, your goal should be to install or service the system so that it operates safely and efficiently.

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

● 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 warnings and caution notices given in this manual.

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

This symbol indicates a hazard or unsafe practice which can result in personal injury, 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, reconnected, and/or checked.

● Highly dangerous electrical voltages are used in this system. Carefully refer to all wiring diagrams 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 securely. Loose wiring may cause overheating at connections and become a possible fire hazard.

› When Transporting:

Be careful when picking up and moving indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Watch for sharp edges or thin aluminum fins, as they 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 reinforce it using a strong wood or metal frame to provide added support.

● In a Room

Properly insulate any tubing run inside a room to prevent “sweating” - condensation that can collect and drip, leading to possible 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 unwanted vibration.

● In an Area with High Winds

Securely anchor the outdoor unit down with bolts and additional framing (not supplied). Provide a suitable air baffle.

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

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

› When Connecting Refrigerant Tubing:

△ Use flare method for connecting tubing. △ Apply refrigerant lubricant to matching surfaces of the flare and union tubes before connecting them, then tighten the

nut with a torque wrench for leak-free connection. △ Check carefully for leaks before starting a 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. As stated above, 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.

NOTE:

The figure, size, and parameters of the actual product may not be identical with the service manual; please take actual product as the standard where applicable.

5-2.2 Function Instructions

5-2.2 A - General Technical Parameters

• Maximum distance between remote and receiver (on front of indoor air conditioner): 8m.

• Remote receiver angle: Less than 60 degrees.

• Temperature control accuracy: ±1ºC.

• Time error: Less than 1%.

5-2.2 B - Functions of the controller

• Display panel of the remote

· Control functions of the remote controller (See operating and installation manual)

• Display of the indoor unit Information on the screen:

· 7-segment tube: Displays set temperature or indoor temperature; also displays fault code when a problem is detected.

The error code is displayed when the indoor unit CPU receives a diagnostic alert signal, and will flash for 5 seconds.

· Running LED: Turns on during operation; flashes when the unit defrosts.

· TIMER LED: When timer mode is active, the LED is lit.

· Sleep LED: When sleep mode is active, the LED will be lit; after 10s, the LED will turn itself off.

· Compressor LED: When compressor is running, the LED will be lit.

· Remote control receiver: This component receives signals from the remote control and is wired onto the display board.

5-2.2 C - Control functions

• Emergency switch

When the system is connected to power the first time and turned on, it will automatically be in Auto mode. If you

press the “ON/OFF” button during normal operation, the system enters 'Stand-by state' and settings are saved.

When the system enters Stand-by state (due to an emergency power loss or other shutdown event), most settings will be saved and restored when power is restored and the unit is turned back on. Settings saved include: Operation Mode, Air Volume, Temperature Setting, and Forced Cooling. The only setting lost is Air Flow Direction.

To turn on the system without a remote from Stand-by state, press and hold the emergency switch for 5 seconds. A buzzer will sound once, and it will begin operating in cooling mode, with the indoor fan speed set to HIGH; in this emergency mode, you will not be able to adjust the temperature.

If the emergency switch is pressed again or the system receives a remote control signal, it will exit this mode, and

will operate as usual based on the new corresponding commands from the remote.

• Operator-machine communication

If the system has the i-Feel function, when set to i-Feel mode by the remote control, the room temperature must be set using the remote control, and the indoor unit will detect the temperature setting from the remote using its sensor. Normally the remote will automatically transmit the control signal at a 10 minute interval (H1 model remotes only; all other models have a 9 minute interval). However, if the room temperature changes in excess of 1°C in a very short period, the remote will detect this and transmit signal every 2 minutes. If the indoor unit has not received a remote signal within 30 minutes, the system room temperature will be set using the internal sensor of indoor unit.

• Timer function

1 Max Timer Length is 24 hours, but can but set in 1 minute increments. 2 Timer can be turned ON or OFF, and set to recur on a regular schedule. 3 Timer accuracy is above 97%. 4 System can have a Timer-ON and Timer-OFF points set at the same time, but no timer setting will be indicated.

32

• Sleep 1 Sleep mode can only be set in Cool, Heat, and Dehumidify ('Dry') mode. 2 When the system runs in Sleep mode, it will stop after 8 hours operation, canceling the Sleep setting. If the

system has a programmed Timer-OFF setting when Sleep mode runs, one of two things will occur:

· If Timer-OFF is set to less than 8 hours away when Sleep mode is engaged, the system will run in Sleep mode only until the TIMER-OFF shutdown triggers.

· If Timer-OFF is set to more than 8 hours away when Sleep mode is engaged, the system will run in Sleep mode until it ends, turning off the system and canceling the Timer-OFF setting trigger.

3 When the Sleep mode is selected with Cooling mode, if the room temperature not less than 26ºC, the

setting temperature will not be adjusted, otherwise, the setting temperature will be raised by 1ºC per hour, but the max setting temperature raise is 1ºC.

4 When the Sleep mode is select with Heat mode, the setting temperature will be decreased by 1ºC per hour

during the successive 3 hour, but the max setting temperature decrease is 3ºC.

5 When the appliance operate with Sleep mode, the indoor fan run in the LOW setting, and the air flow

direction same as the last setting and the temperature and air flow direction can be adjusted by user. The Running indicator will be flashed 10 times per 1 Hz frequency, then all the indicators turn OFF except the Sleep light after 5 min elapse. Those indicators will be recovery when the temperature or Time setting is adjusted, after the setting, the indicators will be lit in 10 sec, then turn OFF.

• Automatic run (SMART) mode

When the appliance operates in Smart Mode, the air flow direction can be adjusted.

1 H/C appliance a. When the temperature setting is 26ºC, the unit will run in Cool mode if the room temperature exceeds 26ºC. b. When the room temperature exceeds 23ºC, but is below 26ºC, it will run in Dry mode.

(It will switch to Automatic setting after 3 min LOW air volume running.)

c. When the room temperature exceeds 21ºC, but is below 23ºC, it will run in Fan only mode, with the air volume set to LOW and fan speed can be adjusted.

d. When room temperature is not more than 21ºC, it will run in Heat mode, and the temperature is set to 22ºC. 2 Cool only appliance a. When the room temperature exceeds 26ºC, it will be ran in Cool mode, and the temperature is set to 26ºC.

b. When the room temperature exceeds 23ºC, but not more than 26ºC, it will be operated in the Dry mode. c. When the room temperature is not more than 23ºC, it will be operated in the Fan only, the air volume set to LOW and the fan speed can be adjusted

After the appliance start the smart operation, the setting temperature can be adjusted 2ºC or 7ºC (based on the remote mode; min accuracy is 1ºC) up and down base on the automatic temperature setting, also the presetting temperature of PCB circuit.

In case of the specific operation selected, it could be re-select the other modes after the compressor ceased for 5

min or the setting temperature changed.

33

• Cooling-run mode

Outdoor Fan Operation

The outdoor fan’s speeds except the single speed motor can be changed according to outdoor ambient temperatures. When operating at a fixed frequency, the outdoor fan is forced to operate at the high speed.

Indoor Fan Operation

· When the indoor fan keep in running condition, this operation state could be controlled by the remote control with

High, Median, Low and Automatic setting.

· When the appliance is set Automatic condition in the Cool mode for the first time, the fan speed will run at Low

setting. After that, temperature and fan speed is shown as following.

When the difference between setting temperature and room temperature equal 2ºC or 4ºC, indoor fan speed will

remain steady.

Air flow direction control

The louver is derived by a step motor, and it swings the horizontal louver automatically. Press the SWING button to

swing or stop the louver.

During the louver swing in normal operation, the current position will be stored. When the appliance turn off and

louver swing automatically to the default position, it will position at the close position plus 5º.

4-way valve

· State: It is interrupted in cooling.

· Switchover: When initially powered on for cooling, the 4-way valve is interrupted immediately.

When the heating is changed to the cooling, it needs an interval of 50 seconds for the 4-way valve to change over from being activated to being interrupted.

34

• Heating-run mode

Temperature compensation

The temperature compensation is 5º in heating mode. For example, if the set temperature is 25ºC by the remote control, when the room temperature is detected with 31ºC, the compressor will turn off. The main reason is that the hot air is condensed at the top of the house.

› Note: The compensation is available only if the room temperature sensor of indoor unit is used and it is not available when it is subject to the sensor on the remote control.

Indoor fan motor operation

· Anti-cold air system:

When the appliance run in Heat mode condition, the indoor fan motor operation is shown as following to prevent the cooling air come out during the appliance operation.

When the appliance turn in the anti-cold air system in the Extra-LOW (Tapped motor set in LOW, sic passim) during the compressor operation, the louver swing to the Cool air protection position, the louver recovers to the original position after the air volume change to LOW. When the room temperature reach to the setting temperature, the compressor will be turn off, and the air flow change to LOW, the louver swing to the Cool air protective position to prevent the air drop into human body directly; when the indoor pipe coil temperature drop continuously, it will turn in the Cooling air protective system in the Extra-LOW or stop the fan motor.

The indoor fan motor is only controlled by the signal of indoor pipe coil temperature, no matter the compressor turn ON/OFF, even the appliance turn in Heat mode at first time.

The indoor fan motor will operate according to the different setting(High, Median, Low and Automatic) by the remote control, but the anti-cold air system is prior.

When the appliance run in the Heat mode with the Automatic setting at first time, the fan speed will be in the LOW setting, and the operation diagram is shown as following

When the difference between the setting temperature and the room temperature equal to 2℃ or 4℃, the indoor fan speed will keep in current speed.

7-2. Testing the jumper terminals

» Note:

When the whole machine is powered up, if the external unit does not work, to rule out the communications failures, adopt screening method such as short circuit on the jumper terminals to see if the external unit can be started normally or similar method.

There are two blue terminals on the outdoor control panel, as shown above. Application: Short out the terminals, and power up the outdoor unit, then the outdoor unit may run independently. It can be determined that there is no internal and external communication faults.

7-3. Automatic Protection System Diagnosis and Troubleshooting

· Protection diagnosis of the complete machine - (all types of protection during operation, i.e. under-voltage, over-voltage and overcurrent protection)

» Note: List all types of protection that may occur to the complete machine and describe the conditions and signs of the start, course and end of such protection.

7-3.1 Voltage protection

› Protection against AC input over-voltage/under-voltage

¹ • Conditions for protection against AC input over-voltage/under-voltage:

· If the input AC voltage is greater than “protective over-voltage value” or less than “protective under-voltage value” for five seconds, over-voltage/under-voltage protection starts. ² • Protection actions against AC input over-voltage/under-voltage:

· The system stops operation. ³ • Conditions for ending AC input over-voltage/under-voltage:

· If the input AC voltage is lower than “the protective over-voltage value” -10V, or higher than “the protective under-voltage value” +10V, the over-voltage/under-voltage protection will be released.

7-3.2 Current protection:

› Protection against over-current

¹ • Conditions for over-current protection:

· If the current is equal to or greater than “current value for starting the refrigeration current protection (E2 value)” for six seconds, over-current protection starts. ² • Protection actions against over-current:

· Indoor display screen and outdoor indicator give indications, the compressor and outdoor fan stop, but indoor fan runs normally. ³ • Condition for ending over-current protection:

· When the current drops below “current value for releasing the refrigeration current protection (E2 value)”, over-current protection will be released.

› Frequency decreasing for over-current

¹ • Conditions for over-current frequency decreasing:

· If the current is equal to or greater than “current value for starting the refrigeration current protective frequency decreasing (E2 value)”, over-current frequency decreasing starts. ² • Over-current frequency decreasing actions:

55

· The compressor will decrease frequency at rate of (E2 value)Hz/S. The indoor and outdoor fans run. ³ • Conditions for ending over-current frequency decreasing:

· When the current drops below “current value for starting the refrigeration current protective prohibition of frequency rising (E2 value)”, over-current under-clocking will be released.

7-3.3 Prohibition of frequency increasing of compressor exhausting

¹ • Conditions for prohibition of frequency rising of compressor discharge:

· Condition 1: in the case of frequency decreasing of compressor discharge, the discharge temperature of the compressor drops below X4℃.

· Condition 2: in normal operation, the discharge temperature of compressor reaches X5℃.

· If either of the above two conditions is met, prohibition of frequency rising of compressor discharge begins. ² • Actions relates to prohibition of frequency rising of compressor discharge:

· The frequency of compressor maintains at the current level, which may decrease as the case requires while cannot rise. The indoor and outdoor fans run. ³ • Condition for ending prohibition of frequency rising of compressor discharge:

· If the temperature of compressor discharge drops below X6℃, prohibition of frequency rising of compressor discharge will be released.

7-3.4 Prohibition of frequency for anti-overload of outdoor coiled pipe

¹ • Condition for anti-overload prohibition of frequency of outdoor coiled pipe

· In the case of anti-overload frequency decreasing of outdoor coiled pipe, anti-overload prohibition of

frequency of the unit begins when the temperature of outdoor coiled pipe drops below “the anti-overload frequency decreasing temperature of outdoor coiled pipe”.

² • Actions related to anti-overload prohibition of frequency of outdoor coiled pipe

· The frequency of compressor maintains at the current level, which may decrease as the case requires while cannot rise. The indoor and outdoor fans run. ³ • Condition for ending anti-overload prohibition of frequency of outdoor coiled pipe:

· If the temperature of outdoor coiled pipe drops below "temperature to release the anti-overload state of outdoor coiled pipe," anti-overload prohibition of frequency of outdoor coiled pipe will be released.

7-4. Troubleshooting Diagnosis for Compressor

Judging the connecting terminals of inverter compressor:

It is impossible to identify terminals U, V and W of inverter compressor with multi-meter. Just connect the terminals in the same way as the original unit when replacing the compressor. A wrong connection will lead to reverse and loud noise of the compressor.

Resistance of compressor coil:

• Measure the resistance between any two terminals, which are about a few Ohms, three phases having the same resistance.

7-5. Troubleshooting Diagnosis for Electric Filter Board

Visual examination: As the circuit is simple, the connection may be checked visually to see whether any loose or

poor connection.

Voltage test: The voltage at the input end shall be the same as the voltage at the output end.

7-6. Troubleshooting Diagnosis for Electric Communication Issues

Step 1. Determine whether the connecting cables and tether cables of indoor/outdoor units are correctly

wired. If not, change wiring order and test connection.

Step 2. Determine whether there is loose connection. Fasten the connection in the case of loose connection and

then conduct verification.

Step 3. Measure the voltage between SI and N with multi-meter and see whether the voltage fluctuates

between 0V and 24V. Please directly replace indoor and outdoor control boards if there are not voltage fluctuations.
