• This appliance must not be used by children; the appliance and its power cord must be kept away from children.

• This appliance has been designed for air conditioning domestic environments (indoor operation only) and must not be used for any other purpose, such as for drying clothing, cooling food, etc.

The installation must be in accordance with regulations of the country where the unit is used. If case of doubt about the electrical installation, it shall

be checked and if necessary modified by a qualified electrician.

• The appliance must be plugged into an outlet that is properly installed and earthed.

• Before plugging into a socket, it shall be ensured that the mains voltage matches the voltage specified on the rating plate of the appliance.

• The appliance shall not be operated with a damaged cord or plug, or after the appliance malfunctions, or has been damaged in any manner. It shall be returned to the nearest authorized service facility for examination, repair or adjustment.

- INSTALLATION

General information

• When moving the machine, make sure that it is in an upright position.
  Do not install the air conditioner in a room where frost may occur. There is a risk of damage if the condensate water freeze in the device or its pipe.
  While adjusting the upper and lower wind-guide strips of the air outlet, pluck it with hands gently to avoid damaging wind-guide strips.

Instructions

Select mounted place

Install the air conditioner in a flat and dry place, with a minimum clearance of 50cm around the unit to enable smooth circulation of air, as shown in Fig. 3 (before connection of exhaust pipe).

Assembly method of exhaust pipe (For COOL Mode)

• Extend either side of the pipe and screw the pipe to adaptor (Fig. 4).
  Insert the round ending of the exhaust pipe into the rear air outlet of the air conditioner, as shown in Fig. 5.
• Connect the oval ending of the connected exhaust pipe with the window slide bar connector.

Fig. 3
Fig. 4

Fig. 5

• Make sure the exhaust pipe is firmly attached to the oval connector that fits into the window slide bar. Snap pipe connector into the window slide bar opening.

Caution

To ensure proper drainage, make sure that the exhaust pipe does not have any sharp bends or sags.
The pipe can be extended from 60~cm to 170~cm (including adapter). Consider keeping the length of the pipe to minimum required to save energy.
This length has been designed especially to the specifications of the air conditioner. Do not use an extension or exchange for a different pipe as that may lead to malfunctioning.

Installation of window sealplate

Design of window sealplate complies with most standard horizontal or vertical windows, and the installation methods are shown in Fig.8 and 9.

After selecting the COOL mode, press SLEEP on the remote control (or Timer button + Down button together on the control panel) to choose Sleep mode. Both upper and lower fans are forcibly set at LOW speed. Under this mode, after the unit operates for 2 hours, the setting temperature raises 1^ automatically. After operating for another 2 hours, the setting temperature raises 1^ again. After that, the setting temperature won't change. Press SLEEP again to cancel this function.

Caution:

• When WATER FULL indication is displayed, the air conditioner will stop operating until the condensate water has been drained. After drainage, the air conditioner will start automatically.
  If you turn the air conditioner off and immediately restart it, or in the event of a power failure during use, allow 3 minutes for the compressor to restart cooling. There is an electronic device in the unit that keeps the compressor turned off for three minutes for safety.

DEHUMIDIFY mode

Press MODE until the DEHUMIDIFY indicator lights on the panel.
o Temperature and speed are not adjustable when this mode is selected.

Important: for best efficiency in dehumidifying mode, make sure that windows and doors are kept closed.

FAN mode

Press MODE until the indicator lights on the panel.
Press SPEED to select appropriate speed. LOW and HIGH speeds can be circularly selected (high > low > high).
o Temperature is not adjustable when this mode is selected.
The sleep function is not available for the fan mode.

Timer setting

Timer on

• When the unit is in standby, first press TIMER button to go to delay stop setting (from 0.5h to 24h), until the indicator LED lights. The display will blink.
• Tap or hold the UP or the DOWN arrow to change delay stop timer at 0.5 hour increments up to 3 hours, then at 1 hour increments up to 24 hours.
  During this setting procedure, the operating modes after start can be selected; if the cool mode is selected, the temperature can be adjusted simultaneously. After the set time expires, the air conditioner starts automatically and runs in the selected operating mode.

Timer off

• When the air conditioner is running, press the TIMER button, the timer indicator LED is on, and the display will blink.
  Press UP and DOWN to adjust time as shown previously.

o Condensation water that forms during cooling or dehumidifying will drop into an inbuilt bottom tray.
- When the appliance is activated in humid weather, more condensate water is produced. The WATER FULL alarm will be issued if the water level of the bottom tray reaches a predetermined level; the air conditioning/dehumidification process will immediately stop, however, the fan motor will continue to operate (this is normal).
The WATER FULL indicator will light up on the display and an signal will be issued simultaneously 10 times every 5 min, until the level in the water tray gets lower than the alarm level or the water tray has been drained manually.
Carefully move the unit to a drain location, unscrew nut and pull out the water plug to drain all water.
- When the alarm is relieved, the air conditioner will resume normal operation automatically.
o Be sure to reinstall the nut and the water plug before using the unit.

Caution: when the WATER FULL indicator light turns on, please move the air conditioner steadily, otherwise, the water may overflow from the inside.

Advice

• Never remain exposed directly to the flow of cold air for a long time, as direct and prolonged exposure to cold air from the air conditioner could be dangerous for your health. Take particular care in rooms where there are children, old, or sick people.
  Do not direct the airflow into plants or animals, as long and direct exposure to cold air from the air conditioner could adversely affect them.
  To help cooling efficiency, keep blinds and curtains closed during the sunniest part of the day.
• Do not drink or cook with water drained from air conditioner; It contains contaminants and could make you sick.
• Ventilate the room periodically during use, especially if using gas appliances in conjunction with the air conditioner, as an oxygen shortage may occur.

- CLEANING AND MAINTENANCE

Cleaning

Clean the surface of the air conditioner with duster or semi-wet soft cloth. Do not use chemical solvents such as gasoline and alcohol.
If the machine is indeed very dirty, wipe it with neutral cleaner.

Fig. 15

Maintenance

If the strainers are blocked by dust, the air circulation will be impeded, reducing the efficiency of the air conditioner.

Cleaning the strainers once every two weeks is recommended.

Take out the strainers frame gently in the direction shown by the arrow in Fig.15.
First take out the strainer unit 1 and then the strainer unit 2.
Put strainers into warm water with neutral detergent (about 40^ ), rinse and then dry them in the shade.
Reinstall the strainers in their original position.
O First replace the strainer unit 2 and then the strainer unit 1.

Caution: please turn off the air conditioner and pull out the plug before cleaning and maintenance.

STORAGE

At the end of the season or if the air conditioner is no longer used, follow the simple steps below before storing the portable air conditioner.

Drain water from the bottom tray and the unit (water can be poured out by slowly leaning the body backward during drainage).
o Keep the appliance running on FAN mode for half a day in a warm room to dry the appliance inside and prevent mold formation.
Clean the strainers if necessary.
Turn off the air conditioner and unplug it, wrap the power cord around the hooks at the back of the device.
○ Remove the exhaust pipe and store it aside.
o Remove the batteries from the remote control
o Cover the air conditioner with a plastic bag. Store in a dry place, keep it out of the reach of children and take dust control measures.
