REMOTE CONTROLLER MANUAL

NAMES AND FUNCTIONS OF REMOTE CONTROL UNIT

REMOTE CONTROLLER

• This controls the operation of the indoor unit. Signal range to reach indoor unit is about 7 meters. If inverter lamp is used, the range of control may be shorter.
• This unit can be fixed on a wall using the fixture provided. Before fixing it, make sure the indoor unit can be controlled from the remote controller.

COOLING OPERATION

• Use the device for cooling when the outdoor temperature is 21 ~ 46°C.
• If indoors humidity is very high (over 80%), some dew may form on the air outlet grille of the indoor unit.

NOTE

HI fan speed mode selected

• When unit has been operating for a long period of time and the difference between remote controller setting temperature and actual room temperature is continuously large, the fan speed may increase causing higher air blow sound.
• During the time, cooling capacity will be maximized. If the air blow sound causes any discomfort, please select “AUTO” or other than “HI” fan speed.

SILENT OPERATION

NOTE:
Under SILENT mode operation and quiet environment, phenomena like flowing noise of refrigerant in the refrigerating cycle may occur, but this is normal for the operation.

DEHUMIDIFYING OPERATION

• Use the device for dehumidifying when the room temperature is over 16°C.
• When it is under 15°C, the dehumidifying function will not work.

Dehumidifying Function

• When the room temperature is higher than the temperature setting: The device will dehumidify the room and reducing the room temperature to the preset level.
• When the room temperature is lower than the temperature setting: Dehumidifying will be performed at the temperature setting slightly lower than the current room temperature, regardless of the temperature setting. The function will stop (the indoor unit will stop emitting air) as soon as the room temperature becomes lower than the setting temperature.
• You might feel a bit colder in dehumidifying operation.

FAN OPERATION

In Fan operation mode the device is function as an air circulator.

FAN Function
During FAN operation, compressor does not run and there is no cooling operation with only indoor fan running.

ONE-TOUCH POWERFUL MODE

If feeling so cold, cancel this powerful mode as mentioned in “CANCELLATION of POWERFUL operation”.

CANCELLATION of POWERFUL Operation

HOW TO SET THE AIR SLEEP TIMER

Press the button, and the display changes as shown below.

• Air Sleep Timer: The device will continue working for the designated number of hours and then turn off.
• Point the signal window of the remote controller toward the indoor unit, and press the AIR SLEEP TIMER button.
• The timer information will be displayed on the remote controller. The TIMER lamp lights with a beep from the indoor unit.

Explanation of the air sleep timer

• The device will control the FAN SPEED and room temperature automatically so as to be quiet and good for people’s health.
• You can set the sleep timer to turn off after 1,2,3 –➞ 9 or 10 hours. The FAN SPEED and room temperature will be controlled as shown below.

Operation with the air sleep timer

REFRESH MODE OPERATION

To slightly reduce air blow temperature of air conditioner and room humidity if unit has been operating for a long period of time for the day.

NOTE
The effectiveness of Refresh operation may not be significant in the following situation:

1. Cooling operation operates for a short time.
2. Unit is operated under high load condition such as to cool a big room, room which is directly expose to sunlight and high outside temperature.
3. Temperature setting by the remote controller is lower than recommended temperature for cooling operation (refer page 3)

HOW TO SET THE TIMER

ON Timer and OFF Timer are available.

• OFF Timer Reservation
  Operation stop at setting time

• ON Timer Reservation
  Operation will start for setting temperature at setting time.

AIR FLOW LOUVERS ADJUSTMENTS

1. Adjustment of the conditioned air in the upward and downward directions.

   • The horizontal air deflector is automatically set to the proper angle suitable for each operation. The deflector can be swung up and down continuously and also set to the desired angle
     using the “ (AUTO SWING (HORIZONTAL))” button.

   • If the “ (AUTO SWING (HORIZONTAL))” button is pressed once, the horizontal air deflector swings up and down. If the button is pressed again, the deflector stops in its current position. Several seconds (about 6 seconds) may be required before the deflector starts to move.

   • Use the horizontal air deflector within the adjusting range shown on the right.

   • When the operation is stopped, the horizontal air deflector moves and stops at the position where the air outlet closes.

   • CAUTION
     In “Cooling” operation, do not keep the horizontal air deflector swinging for a long time. Some dew may form on the horizontal air deflector and dew may drop.

2. Adjustment of the conditioned air to the left and right.
   Hold the second vertical air deflector of each set of vertical air deflectors from right as shown in the figure and adjust the conditioned air to the left or right.

WARNING
Do not insert a finger, a rod or other objects into the air outlet or inlet as the fan is rotating at a high speed, it will cause injury. Before any cleaning or adjusting the deflectors, be sure to switch OFF the operation.

FROST WASH OPERATION (GENERAL INFORMATION)

Cleaning function by frosting the indoor exchanger and allowing melted water to wash away dust particles collected on surface of exchanger. This function only applicable during OFF mode.

Note

• Operate FROST WASH when under the following conditions
  • Outdoor temperature 21°C ~ 43°C
  • Indoor temperature 21°C ~ 32°C
• During FROST WASH operation, there could be sound generated during frosting and defrosting of heat exchanger.
• FROST WASH operation is only available when unit is in standby mode.
• During FROST WASH, LED Indicator will lit up.
• If air conditioner cumulative operation time has passed, LED indicator will blink as reminder to user to operate FROST WASH function. (Blinking remain for max. 4 min. after stopping operation)
• FROST WASH is recommended to be operated every 2 weeks. Not operate FROST WASH would cause accumulation of dust or particles which would be diffi cult to be removed. In this case, manual servicing will be recommended.
• Failure to operate FROST WASH regularly, heat exchanger would be difficult to be cleaned up. If operate FROST WASH when much dust has accumulated on heat exchanger, fallen dust would cause the clogging of the drain fl ow path.

CAUTION

• During “FROST WASH” operation, please do not open the door and windows. Water will condense on unit surface and drip down.
• During “FROST WASH” operation, please do not open and remove the Front Panel. It may cause injury or malfunction.

FROST WASH (MANUAL OPERATION)

HOW TO EXCHANGE THE BATTERIES IN THE REMOTE CONTROLLER

When using the remote control, if there is no response from the air conditioner unit and or the remote control has fading and dim displays, the batteries in the remote control device need to be removed and replaced with new ones

1. Remove the cover as shown in the figure and take out the old batteries.
2. Install the new batteries.
   The direction of the batteries should match the marks in the case.

CAUTION

1. Do not use new and old batteries, or different kinds of batteries together.
2. Take out the batteries when you do not use the remote controller for 2 or 3 months.
3. Use high quality and high performance AAA batteries to avoid short operating life and electrolyte leakages.
4. After batteries are replaced or when an operation is abnormal, press the reset button with a pen point.
