direction
Note: Screw adapter into right position, at least 3 laps, to keep good connection of exhaust hose assembly and
its adapter
1.2 Installation of the exhaust hose assembly into unit
1) Determine window seal-plate position, vertical or horizontal direction.
2) If window seal-plate will be in horizontal position, the slant panel Aof adapter should be upwards.

10
3) If window seal-plate will be in vertical position, and will be at left side of window, the slant panel A of adapter
should be at right direction.
4) If window seal-plate will be in vertical position, and will be at right side of window, the slant panel A of
adapter should be at left direction.
1. Take two ends of exhaust hose and its adapter assembly
2. Put front end of exhaust hose assembly onto jugged position of exhaust outlet of back panel.
Remark: Keep the right direction of slant side A of adapter, for ease installation of window seal-plate.
3. Hold the unit by one hand, carry the exhaust hose assembly with another hand and push it into unit gently,
for good lock of two parts.

1.4 Installation of the unit
1. Move the unit together with its exhaust hose assembly infront of the window and keep the unit at least 50cm
away from the walls or other objects. (As Photo).
2. Install the rectangle end of exhaust hose adapter into the corresponding rectangle hole in window seal-plate
assembly, fix it with screw and close the window (as Photo).
A. Align the 4 openings on window seal-plate with corresponding 4 openings on exhaust hose adapter
and set them together, then slide adapter downwards, to make 2 set of openings locked for 2 parts
good connection.
B. Lock self-tapping screw φ4mm into adapter hole.
Remarks:
Slide the adapter downwards and assure the adapter installed in good position.
Lock the screw tightly to avoid fall off.
Exhaust hose can’t be bent or with flexure higher than 45°, in order to keep good ventilation of exhaust
hose.

12
Important notes:
The exhaust hose is 280mm-1500mm long and which is determined by the specification of the
air-conditioner (s). Do not use prolonged the hose or replace it with other different hoses as this may affect the
functions of the air-conditioner. The exhaust hose must be smooth or it may lead air-conditioner overheat and
trip because exhaust hose is obstructed.
VIII. Drainage Instruction
This portable air conditioner has two drain ports - an upper drain port and a lower drain port. It also has two
drainage methods that can be used - manual drainage and continuous drainage.
1. Manual drain:
This unit is designed with a highly efficient self-evaporative system and it is suggested to use manual drainage in
cooling mode. Condensate will recycle in the unit to cool the condenser and enhance cooling performance.
However in extreme humidity, the water tank in the chassis will fill up and “FL” will show on the LED display. When
this happens the water tank needs to be drained manually from lower drain port.
Put a shallow tray below the lower drain port at the back of the unit.
Screw off the drain port cover and then remove the water stopper to allow water flow into the tray.
After water has stopped flowing, plug in the water stopper back in and screw the drain port cover back onto
the drain port tightly.
NOTE:
To avoid leaks, if it is necessary to move the unit always turn off the unit and make sure it is drained properly
before moving.
If the drain port cover or water stopper are damaged during use, they should be replaced with new ones.
Tilt the unit slightly backwards when draining.
If the shallow tray has insufficient capacity to hold all the water that is draining, block the drain port with the
water stopper before the tray is full, empty the tray, and then restart the draining process.
The water stopper and drain port cover must be fitted properly to avoid leakages.
2. Continuous drain:
1) Screw off the drain cover and unplug the water stopper.
2) Connect drain-hole drain hose
3) Pull the drain hose to bathroom or outdoor.

Drain hose must be installed before unit starts working.
When unit is operating in cooling mode, to ensure enough water to recycle in the unit to cool condenser and
enhance cooling performance, so it is not suggested to use continuous drainage
Put the drain hose in an inaccessible place, not higher than drainage hole and keep drain hose straight
without any flexure.
Keep the drain cover and its stopper properly installed when continuous drainage is adopted.
IX. Maintenance and Service
Turn off the unit and pull out the plug before maintain or send the unit to service center.
1. Surface cleaning

avoid any damage to unit.
2. Filter cleaning
Clean the filter every two weeks, otherwise it would influence the unit performance if filter clogged with dust.
2.1 How to clean filter
Grip the filter handle and take it out gently in correct direction shown by the arrow.
Take out filters of back panel at first then side panel.
Clean the filters gently in warm water (about 40℃(104℉)) mixed with detergent, and dry in the shade
Use even force to take out the filter to avoid any twist or damage to filter.
Notes:
Do not squash the mesh.
