NOTE:

1. Optimum performance will be achieved within these operating temperatures. If air conditioner is used outside of the above conditions, certain safety protection features might come into operation and cause the unit to function abnormally.
2. If the air conditioner runs for a long time in cooling mode and the humidity is high (over 80%), condensed water may drip out of the unit. In this case, set the vertical air flow louver to its maximum angle (vertical toward the floor), and set it to HIGH fan mode.

Manual Operation
Units are equipment with a switch to run emergency operation mode. It can be accessed by opening the front panel. This switch is used for manual operation in case the remote fails to work or maintenance is necessary.

NOTE: The unit must be turned off before operating the manual control button. If the unit is operational, continue pressing the manual control button until the unit is off.

1. Open and lift the front panel up to an angle until it remains fixed with a clicking sound.
2. One press of the manual control switch will lead to the forced AUTO operation. If the switch is pressed twice within five seconds, the unit will operate under forced COOL operation.
3. Close the panel firmly to its original position.

CAUTION

• This switch is used for testing purposes only. /
  Please do not use it unless necessary.

•  To restore the remote control operation, use the remote control directly.

Airflow Directional Control

• Adjust the airflow direction properly.
  Otherwise, it might cause discomfort or uneven room temperatures.

• Adjust the vertical louver using the remote.

• Adjust the horizontal louver manually.

Adjust Vertical (Up / Down) Air Flow using Vertical Louver (fig2.2):
Perform this function while the unit is in operation. Use the remote control to adjust the Vertical Louver / Vertical Air Flow direction. The vertical louver can move in small increments for each press, or continuously swing up and down automatically. Please refer to the “REMOTE CONTROL USER MANUAL” for details.

Adjust Horizontal (Left/ Right) Airflow using Horizontal Louver (fig 2.3, fig 2.4):
Move the Deflector Rod manually to adjust the air flow side to side (left / right) as desired.

CAUTION
DO NOT Do not put your fingers into the panel of the blower and suction side. The high speed fan inside may cause injury.
DO NOT operate the unit for long periods of time with the airflow direction set downward in cooling or dehumidifying mode. Otherwise, condensation might occur on the surface of the vertical louver causing moisture to drop on to the floor or furnishings .
DO NOT move the vertical louver manually.
Otherwise, the vertical louver will be out of sync. IF this happens, cease operation, turn off power to the unit, remove the wireless module from the front cover, turn off power to the circuit (at the breaker), wait for a few seconds and turn power back on at the breaker, reinstall wireless module and power the unit back on.

1. After a quick restart, the vertical louver may remain static for approximately 10 seconds.
2. Open angle of the vertical louver should not be set too small, as it will restrict airflow and reduce COOLING and HEATING performance.

How the air conditioner works

Basic Operation MODEs:
AUTO / COOL / DRY / HEAT (Model dependent).

Auto Operation:
When you set the air conditioner in AUTO mode, it will automatically select cooling, heating or fan-only operation depending on set temperature and room temperature.
The unit will control the room temperature automatically, according to the temperature point you set.

SLEEP Operation:
When selected, the temperature will increase while cooling or decrease while heating by 1C / 2F per hour for the first 2 hours. Thereafter it keeps this new temperature for 5 hours before SLEEP mode switches off.

DRYING Operation:
The temperature is regulated while dehumidifying by intermittently switching the cooling or fan-only operation on and off. The fan speed is set to LOW.

HEATING Operation:
This unit is a heat pump by design. By reversing the air conditioning process, it absorbs heat from outdoors and transfers it to the indoor unit. As a result, the operating performance and efficiency is reduced as the outdoor air temperature drops. If you feel that the heating performance is insufficient, it is recommended that you supplement heating with other appliances.

Optimal Operation:
To achieve optimal performance, please note the following:

• Adjust the airflow direction correctly, so that it is not towards people or at an extreme angle.

• Adjust the temperature to achieve moderate comfort levels. An excessively low or high temperature setting wastes energy.

• Keep windows and doors closed, as this improves performance.

• Limit energy usage (run time) by using the TIMER function.

• Do not put any objects near the air inlets / outlets.
  Doing so would impair performance and possible shut down the unit.

• Inspect the air filters periodically, and clean them as needed.

Special Functions
Refrigerant Leakage Detection:
When refrigerant leakage is detected, the indoor unit will display “EC” code or flash LEDs.

Louver Angle Memory Function (optional):
Within the scope of the safe operation angle, the horizontal louver angle is memorized and will return to the position last selected by the user. If it exceeds the safe operation angle, it will default within the safe operation range. However, it will not return to  safe operation angle when Turbo mode is set or the unit is in manual control or after a power interruption. Subsequently, it is strongly recommended that the horizontal louver angle not be set too small, to avoid possible condensation leakage.

Self Clean Function:
Airborne bacteria can grow in the moisture on indoor heat exchangers. Regular drying of the exchanger prevents growth. By simply pressing the SELF CLEAN button on the remote, the system will automatically manage the process. This cleaning function can be performed as often as desired.

• The unit will operate in the following sequence:
  FAN mode on LOW then HEAT mode with LOW fan speed then FAN mode on LOW then STOP operation and turn off.

• This function can only be activated in COOL or DRY modes

• It is recommended to allow the unit to run in COOL mode for at least 30 minutes before activation.

• Pressing the SELF CLEAN button again will cancel the operation.

Optimal Operation:
In the event of a power interruption such as a blackout, the air conditioner will stop. It will then restart automatically and resume the previous operation when the power supply returns.

WIFI Control Function
Connect the wireless control module via the USB port in the back of the front cover of the indoor unit for the unit to be controlled by remote control and/or smartphone app.

Mute Function (optional)
Press the LED button on the remote to turn off the LED display and silence the buzzer of the indoor unit, creating a quiet comfortable environment.

Care and Maintenance

Before maintenance turn the power off to the unit. Then, disconnect the power to the circuit at the breaker.

Cleaning the Unit:
Wipe the unit with a soft dry cloth. If the unit is very dirty, wipe it with a cloth soaked in warm water. Do not use bleach or abrasives.

Cleaning the Air Filter and Air Freshener:
A clogged air filter can greatly reduce the heating and cooling efficiency of this unit. It is recommended to clean the unit every 2 weeks.

1. Open the front panel by carefully lifting both ends at the same time. At a certain angle, there will be an audible click and the lid becomes self-supporting. For some models suspension bars are provided and required to prop up the lid.

2. Use the filter tabs to lift the filter slightly upward and then toward you.

3. Then, extract the filter by gently drawing it downward. Replace as necessary.

4. Unclip the small air freshening filter from the the larger air filter.
   Replace as necessary. Otherwise, clean it with a vacuum and clip it back into place after cleaning the larger air filter as outlined in step 5.

5. Clean the large air filter with soapy water. Rinse with fresh water.
   Shake off excess water and dry in a cool area.

6. Re-clip air freshening filter into large air filter.
   CAUTION
   • Power supply must be disconnected before attempting to clean or service.
   • Do not use benzene, thinner, polishing powder, or similar solvents for cleaning. These may cause the plastic to crack and/or deform.
   • Do not use chemically treated cloth or duster to clean the unit.
   • Never use water hotter than 40°C / 104°F to clean the front panel, it could cause deformation and/or discoloration. CAUTION
   • DO NOT touch the metal parts of the unit when removing the filter. Injuries can occur when handling the sharp metal edges.
   • DO NOT use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.
