Unit Parts And Major Functions

The air conditioner turns to FAN ONLY mode from COOL or HEAT (for cooling and heating models only) mode.
When the indoor temperature reaches the set temperature setting, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode to the set point.
Droplets of water may form on the surface of the indoor unit when cooling occurs in relatively high humidity (defined as higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.

Heating mode (For cooling and heating
models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature cannot be achieved with the air conditioner alone, it is recommended that you use a supplementary heating device.
Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit from its power source and then re-connect the unit with the power source again. Push the ON/OFF button on the remote controller to restart operations.

Energy Saving Tips
· DO NOT set the unit to excessive temperature levels. · While cooling, close the curtains to avoid direct sunlight. · Doors and windows should be kept closed to keep cool or warm air in the room. · DO NOT place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit. · Set a timer and use the built-in SLEEP/ECONOMY mode if applicable. · If you don’t plan to use the unit for a long time, remove the batteries from the remote control. · Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency. · Adjust louvers properly and avoid direct airflow.

Closing curtains during heating also helps keep the heat in

Doors and windows should be kept closed

Manual Operations And Maintenance

Manual Operations And Maintenance

Operation mode selection

Optimal operation

While two or more indoor units are simultaneously operating, make sure the modes do not conflict with each other. The heat mode claims precedence over all other modes. If the unit intially started to operate in HEAT mode, the other units can operate in HEAT mode only. For example: If the unit intially started operates under COOL (or FAN) mode, the other units can operate under any mode except HEAT. If one of the unit selects HEAT mode, the other operating units will stop operation and diplay “–” (for units with display window only) or the auto and operation indication light will flash rapidly, the defrost indication light will turn off, and the timer indication light will remain on (for units without a display window). Alternatively, the defrost and alarm indication light (if applicable) wil light up, or the operation indication light will flash rapidly, and the timer indication light will turn off ( for the floor and standing type).

To achieve optimal performance, please note the following:
· Adjust the direction of the air flow so that it is notblowing directly on people.
· Adjust the temperature to achieve the highest possible level of comfort. Do not adjust the unit to excessive temperature levels.
· Close doors and windows in COOL mode or HEAT mode.
· Use the TIMER ON button on the remote controller to select a time you want to start your air conditioner.
· Do not place any object near the air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner may stop running.
· Clean the air filter periodically, otherwise cooling or heating per formance may be reduced.
· Do not operate unit with horizontal louvre in closed position.

Maintenance
If you plan to leave the unit idle for a long time, perform the following tasks: 1. Clean the indoor unit and air filter. 2. Select FAN ONLY mode and let the indoor fan
run for a time to dry the inside of the unit. 3. Disconnect the power supply and remove the
battery from the remote control. 4. Check components of the outdoor unit
periodically. Contact a local dealer or a customer service centre if the unit requires servicing.
NOTE: Before you clean the air conditioner, be sure to switch off the unit and disconnect the power supply plug.

Suggestion: For units that feature an electric heater, when the outside ambient temperature is below 0°C (32°F), it is strongly recommended that you to keep the machine plugged in so as to guarantee smooth operation.
When the air conditioner is to be used again:
· Use a dry cloth to wipe off the dust accumulated on the rear air intake grille in order to avoid the dust being dispersed from the indoor unit.
· Check that the wiring is not broken off or disconnected.
· Check that the air filter is installed. · Check if the air outlet or inlet is blocked after
the air conditioner has not been used for a long time.

Common Issues The following problems are not a malfunction and in most situations will not require repairs.

Problem
Unit does not turn on when pressing ON/ OFF button

Possible Causes
The unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/ Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s anti-cold wind is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor temperature is too cold and the unit’s anti-freeze protection is activated in order to defrost the unit.

The unit changes from COOL mode to FAN mode

The unit changes its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit will resume operating when the temperature fluctuates again.

The indoor unit emits white mist

In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.

Both the indoor and outdoor units emit white mist

When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.

Troubleshooting

Problem
The indoor unit makes noises

Possible Causes
A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.

Both the indoor unit and outdoor unit make noises

A low hissing sound may occur during operation. This is normal and is caused by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard when the system starts, has just stopped running or is defrosting. This noise is normal and is caused by the refrigerant gas stopping or changing direction.

The outdoor unit makes noises

The unit will make different sounds based on its current operating mode.

Dust is emitted from The unit may accumulate dust during extended periods of non-use, which

either the indoor or will be emitted when the unit is turned on. This can be mitigated by covering

Outdoor Unit Installation

Refrigerant Piping Connection

NOTE: For quick-connect models, please refer to the internal machine manual for the installation method of the connecting pipe. The external machine manual does not repeat the instructions.
When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.
Connection Instructions ­ Refrigerant Piping
CAUTION
· The branching pipe must be installed horizontally. An angle of more than 10° may cause malfunction.
· DO NOT install the connecting pipe until both indoor and outdoor units have been installed.
· Insulate both the gas and liquid piping to prevent water leakage.
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure efficient operation and minimize the need for future maintenance. 1. Measure the distance between the indoor 2. and outdoor units.
Using a pipe cutter, cut the pipe a little longer than the measured distance.
3. Make sure that the pipe is cut at a perfect 90° angle.

DO NOT DEFORM PIPE WHILE CUTTING
Be extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce the heating efficiency of the unit.
Step 2: Remove burrs. Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed. 1. Hold the pipe at a downward angle to
prevent burrs from falling into the pipe. 2. Using a reamer or deburring tool, remove
all burrs from the cut section of the pipe.
Pipe Reamer
Point down
Step 3: Flare pipe ends Proper flaring is essential to achieve an airtight seal. 1. After removing burrs from cut pipe, seal
the ends with PVC tape to prevent foreign materials from entering the pipe. 2. Sheath the pipe with insulating material. 3. Place flare nuts on both ends of pipe. Make sure they are facing in the right direction, because you can’t put them on or change their direction after flaring.

3. Tighten the flare nut as tightly as possible by hand.
4. Using a spanner, grip the nut on the unit tubing.
5. While firmly gripping the nut, use a torque wrench to tighten the flare nut according to the torque values in above table.
NOTE: Use both a spanner and a torque wrench when connecting or disconnecting pipes to/from the unit.

CAUTION
· Ensure to wrap insulation around the piping. Direct contact with the bare piping may result in burns or frostbite.
· Make sure the pipe is properly connected. Over tightening may damage the bell mouth and under tightening may lead to leakage.

1. When connecting the flare nuts, apply a thin coat of refrigeration oil to the flared ends of the pipes.
2. Align the center of the two pipes that you will connect.

Common Issues

The following problems are not a malfunction and in most situations will not require repairs.

Issue Unit does not turn on when pressing ON/OFF button The unit changes from COOL/HEAT mode to FAN mode
The indoor unit emits white mist

Possible Causes
The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.

Both the indoor and outdoor units emit white mist

When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.

The indoor unit makes noises

A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.

Both the indoor unit and outdoor unit make noises

Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.

Indoor Unit Installation

Installation Instructions ­ Indoor unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the label on the product box to make sure that the model number of the indoor unit matches the model number of the outdoor unit.
Step 1: Select installation location Before installing the indoor unit, you must choose an appropriate location. The following are standards that will help you choose an appropriate location for the unit.
Proper installation locations meet the following standards:
Good air circulation Convenient drainage Noise from the unit will not disturb other
people Firm and solid–the location will not vibrate Strong enough to support the weight of the
unit A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
DO NOT install unit in the following locations:
Near any source of heat, steam, or combustible gas
Near flammable items such as curtains or clothing
Near any obstacle that might block air circulation
Near the doorway
In a location subject to direct sunlight

NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you should leave ample room for a wall hole (see Drill wall hole for connective piping step) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit). However, the unit can accommodate piping to both the left and right.
Refer to the following diagram to ensure proper distance from walls and ceiling:
15cm (5.9in) or more

12cm (4.75in) or more

12cm (4.75in) or more

2.3m (90.55in) or more
Step 2: Attach mounting plate to wall The mounting plate is the device on which you will mount the indoor unit.
Remove the screw that attaches the mounting plate to the back of the indoor unit.

Screw
Secure the mounting plate to the wall with the screws provided. Make sure that mounting plate is flat against the wall.
NOTE FOR CONCRETE OR BRICK WALLS: If the wall is made of brick, concrete, or similar material, drill 5mm-diameter (0.2in-diameter) holes in the wall and insert the sleeve anchors provided. Then secure the mounting plate to the wall by tightening the screws directly into the clip anchors.

Indoor Unit Installation

Page 19

Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions.
2. Using a 65mm (2.5in) or 90mm(3.54in) (depending on models )core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 5mm to 7mm (0.2-0.275in). This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

CAUTION
When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

Step 4: Prepare refrigerant piping The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall. 1. Based on the position of the wall hole relative
to the mounting plate, choose the side from which the piping will exit the unit. 2. If the wall hole is behind the unit, keep the knock-out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand.
Knock-out Panel
3. If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose step. If there is no embedded piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions.
NOTE ON PIPING ANGLE Refrigerant piping can exit the indoor unit from four different angles:Left-hand side,Right-hand side, Left rear, Right rear.

Step 5:Connect drain hose
By default, the drain hose is attached to the lefthand side of unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. Attach drain hose extension (purchased separately) to the end of drain hose.
Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks.
For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation. Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.
NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according to the follo.wing figures.

CORRECT
Make sure there are no kinks or dent in drain hose to ensure proper drainage.

NOT CORRECT
Kinks in the drain hose will create water traps.

Indoor Unit Installation

CAUTION
Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect the unit’s performance.

NOT CORRECT
Kinks in the drain hose will create water traps.

NOT CORRECT Do not place the end of the drain hose in water or in containers that collect water. This will prevent proper drainage.

PLUG THE UNUSED DRAIN HOLE

To prevent unwanted leaks you must plug the unused drain hole with the rubber plug provided.

resulting in product malfunction and possible fire. 10. Do not let wires touch or rest against refrigerant
tubing, the compressor, or any moving parts within the unit. 11. If the unit has an auxiliary electric heater, it must be installed at least 1 meter (40in) away from any combustible materials. 12. To avoid getting an electric shock, never touch

CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal cable, fuse, and switch needed is determined by the maximum current of the unit. The maximum current is indicated on the nameplate located on the side panel of the unit. NOTE: In North America, please choose the right cable size according to the Minimum Circuit

supply has been turned off. After turning off

the power, always wait 10 minutes or more before you touch the electrical components.

WARNING ALL WIRING MUST BE PERFORMED

STRICTLY IN ACCORDANCE WITH THE

WIRING DIAGRAM LOCATED ON THE

BACK OF THE INDOOR UNIT’S FRONT

Back view (For some units only)
Knock-out panel
NOTE: For the units with conduit tube to connect the cable, remove the big plastic konck-out panel to create a slot through which the conduit tube can be installed. For the units with five-core cable, remove the middle small plactic knock-out panel to create a slot through which the cable can exit. Use needle nose pliers if the plastic panel is too difficult to remove by hand.
3. Unscrew the cable clamp below the terminal block and place it to the side.
4. Facing the back of the unit, remove the plastic panel on the bottom left- hand side.
5. Feed the signal wire through this slot, from the back of the unit to the front.
6. Facing the front of the unit, connect the wire according to the indoor unit’s wiring diagram, connect the u-lug and firmly screw each wire to its corresponding terminal.
CAUTION
DO NOT MIX UP LIVE AND NULL WIRES This is dangerous, and can cause the air conditioning unit to malfunction.
7. After checking to make sure every connection is secure, use the cable clamp to fasten the signal cable to the unit. Screw the cable clamp down tightly.
8. Replace the wire cover on the front of the unit, and the plastic panel on the back.

NOTE ABOUT WIRING
THE WIRING CONNECTION PROCESS MAY DIFFER SLIGHTLY BETWEEN UNITS AND REGIONS.
Step 7: Wrappiping and cables Before passing the piping, drain hose, and the signal cable through the wall hole, you must bundle them together to save space, protect them, and insulate them(Not applicable in North America). 1. Bundle the drain hose, refrigerant pipes, and
signal cable as shown below:
Indoor Unit
Space behind unit
Refrigerant piping Insulation tape
Signal wire Drain hose
DRAIN HOSE MUST BE ON BOTTOM Make sure that the drain hose is at the bottom of the bundle. Putting the drain hose at the top of the bundle can cause the drain pan to overflow, which can lead to fire or water damage.
DO NOT INTERTWINE SIGNAL CABLE WITH OTHER WIRES While bundling these items together, do not intertwine or cross the signal cable with any other wiring. 2. Using adhesive vinyl tape, attach the drain
hose to the underside of the refrigerant pipes. 3. Using insulation tape, wrap the signal wire,
refrigerant pipes, and drain hose tightly together. Double-check that all items are bundled.
DO NOT WRAP ENDS OF PIPING When wrapping the bundle, keep the ends of the piping unwrapped. You need to access them to test for leaks at the end of the installation process (refer to Electrical Checks and Leak Checks section of this manual).

Step 8: Mount indoor unit
If you installed new connective piping to the outdoor unit,do the following:
1. If you have already passed the refrigerant piping through the hole in the wall, proceed to Step 4.
2. Otherwise, double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through the hole in the wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that unit is hooked firmly on mounting by applying slight pressure to the left and right-hand sides of the unit. The unit should not jiggle or shift.
6. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.
7. Again, check that the unit is firmly mounted by applying slight pressure to the left and the right-hand sides of the unit.
If refrigerant piping is already embedded in the wall, do the following:
1. Hook the top of the indoor unit on the upper hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit, giving you enough room to connect the refrigerant piping, signal cable, and drain hose.

3. Connect drain hose and refrigerant piping (refer to Refrigerant Piping Connection section of this manual for instructions).
4. Keep pipe connection point exposed to perform the leak test (refer to Electrical Checks and Leak Checks section of this manual).
5. After the leak test, wrap the connection point with insulation tape.
6. Remove the bracket or wedge that is propping up the unit.
7. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.

UNIT IS ADJUSTABLE
Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the unit. If you find that you don’t have ample room to connect embedded pipes to the indoor unit, the unit can be adjusted left or right by about 30-50mm (1.18-1.96in), depending on the model.
